This study explores the contribution of regional taxes and levies to Regional Original Revenue (PAD) in Surabaya City and their role in fostering fiscal independence within the framework of regional autonomy. Employing a descriptive qualitative approach, data were collected from the Surabaya City Regional Revenue Agency and relevant local government offices, complemented by secondary sources such as regulatory documents and literature on regional finance. The data analysis process followed McNabb’s (2002) framework, which consists of categorization, interpretation, generalization, testing alternative perspectives, and refining theoretical insights. The findings reveal that PAD acts as a crucial financial backbone for the implementation of regional autonomy, with taxes and levies serving as the primary contributors. On average, these sources accounted for 89.08% of the total PAD during the 2021–2024 period. The growth trend observed is driven by several factors, including the presence of a comprehensive legal and regulatory framework, diversification of tax types and structures, adequate institutional and human resource capacity, as well as increasing public awareness of tax obligations. Although there was a temporary decline in proportional contribution in 2023, overall tax and levy collections exceeded their targets, underscoring their vital role in supporting government administration and regional development programs. This study emphasizes the need for strengthening regulatory frameworks, enhancing administrative capacity, encouraging greater community participation, and optimizing the use of digital technologies to improve efficiency in revenue collection. These strategies are essential to reduce reliance on central government transfers and to promote greater fiscal independence for Surabaya City.

Breast carcinoma, commonly known as breast cancer, is a type of malignancy that occurs in the milk-producing ducts and sacs of the breast. Breast cancer is the second leading cause of death in Indonesia, after lung cancer. One of the early steps in detecting breast cancer is through breast self-examination (BSE). Although BSE can help detect lumps or abnormalities in the breast, many adolescent girls are unaware of how to perform this examination or its importance. One reason for this is the lack of education regarding the correct method and the significance of performing BSE regularly. Therefore, an effective educational approach is needed, such as peer education, where peers provide information to their fellow students about the importance of self-breast examination. The purpose of this study is to analyze the impact of a peer education program on improving adolescent girls' knowledge of BSE. This research uses a quantitative method with a quasi-experimental design, specifically a one-group pretest-posttest design. The population in this study consisted of female students from grades X and XII at SMK Nurul Islami Semarang, with a sample of 35 students selected through simple random sampling. Data collection was carried out using a questionnaire that included questions about the students' knowledge of self-breast examination. The results were analyzed using the Wilcoxon test, which showed an Asymp Sig (2-tailed) value of 0.000, which is smaller than 0.05. This indicates that the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted, meaning there is a significant effect of the peer education program on increasing adolescent girls' knowledge of BSE. The findings of this study suggest that peer education is an effective method for raising awareness among adolescent girls about the importance of early breast cancer detection, thus encouraging them to perform self-breast examinations more regularly.

The low reading interest and literacy skills of elementary school children in Indonesia remain a problem that requires creative and sustainable solutions. Factors such as limited access to quality books, a lack of reading habits at home, and uninteresting learning approaches are often the causes of a weak literacy culture among students. To address this problem, the Student Community Service Program (KKN) of Sebelas Maret University students in Singodutan Village implemented an activity aimed at fostering a culture of literacy in children through a Reading Book Content-Based Project at SDN 3 Krisak. The concept of this activity integrates reading activities with the creation of creative projects that are appropriate to the content of the reading, so that students not only understand the text but are also able to process the information into real products. This study used a qualitative approach with a phenomenological research type to understand students' experiences during the activity. Data were collected through observation, documentation, and literature review, which were then analyzed descriptively. Activities included selecting reading books appropriate to students' ability levels, shared reading, discussions about the reading content, and the creation of creative projects such as posters, picture stories, or artwork inspired by the reading material. The results of the activity showed an increase in student participation in reading activities, an increase in interest in books, and an improvement in their ability to process information into creative works. Furthermore, students demonstrated greater self-confidence when presenting their work to their classmates.

Writing is a complex and fundamental language skill that plays a central role in developing students’ literacy, particularly in the context of producing negotiation texts. Negotiation texts are one of the text types taught in the Indonesian language curriculum that demand mastery of varied vocabulary, logical coherence, and persuasive language structures. Despite its importance, many students continue to face challenges in composing negotiation texts effectively. Difficulties are often found in choosing the right vocabulary, applying grammatical rules accurately, and constructing arguments that are logically consistent and persuasive. This study aims to analyze the extent to which students’ mastery of Indonesian vocabulary and grammar contributes to their ability to write negotiation texts. The research was conducted on class X students of MAN Kota Mojokerto using a qualitative method with a descriptive approach. Data were collected through three techniques: analysis of students’ written negotiation texts, interviews with teachers and students, and classroom observations during the learning process. The results of the study reveal that most students demonstrate limited mastery of vocabulary, which results in repetitive word choices and restricted expression. In addition, weaknesses in grammar application often lead to inaccurate sentence construction, lack of cohesion, and unclear argument flow. These shortcomings significantly affect the quality of negotiation texts, which tend to be less persuasive, poorly structured, and unable to fulfill the standard criteria of negotiation text writing. Based on these findings, it can be concluded that vocabulary mastery and grammar proficiency play a crucial role in supporting students’ negotiation text writing skills. To address this issue, Indonesian language learning needs to adopt strategies that consistently emphasize writing practice, provide opportunities for vocabulary enrichment, and strengthen students’ grammatical competence. Such approaches are expected to improve students’ literacy levels, particularly in the production of negotiation texts.

Sharia financing is a key instrument that Islamic banks must promote in channeling third-party funds. This aligns with the basic principles of Islamic banking, which emphasize fairness, partnership, and business sustainability. Therefore, it is crucial to examine how various Islamic financing schemes impact Islamic bank profitability. This study focuses on Bank Mega Syariah, using secondary data sourced from quarterly financial reports for the period 2017 to 2024. The financing variables analyzed include musyarakah, mudharabah, murabahah, and ijarah, while profitability is measured using relevant financial performance indicators. The analysis method used is a quantitative approach using regression techniques to examine the effect of each type of financing on bank profitability. The results show that musyarakah, mudharabah, and murabahah-based financing have a positive and significant impact on profitability, meaning that the higher the distribution of these three types of financing, the greater their contribution to increasing bank profits. These findings indicate that the business partnership model, profit-sharing system, and profit margin stipulated in the murabahah contract significantly contribute to maintaining profit growth. Conversely, ijarah financing did not significantly impact profitability. This may be due to the characteristics of ijarah, which tends to be oriented towards fixed assets or leases, resulting in a relatively limited contribution to increasing short-term profits. Overall, this study provides important implications for Islamic bank management to further optimize the proportion of musyarakah, mudharabah, and murabahah financing as a strategy to boost financial performance and maintain business continuity amidst the competitive Islamic banking industry.

Acute Respiratory Infection (ARI) is a disease that attacks the respiratory system and is classified as an infectious disease. This disease can be caused by various types of microorganisms such as viruses, bacteria, or fungi, but most cases of ARI are caused by viral infections. ARI includes conditions such as the common cold, bronchitis, pharyngitis, and pneumonia. In developing countries, ARI is a leading cause of death, especially in children under the age of five. Lack of access to health services, poor sanitation, and malnutrition are factors that contribute to this condition. Therefore, efforts to prevent and treat ARI are crucial, both through conventional and alternative medicine. One herbal plant that has long been used in complementary therapy for ARI is Echinacea, which comes from the flowering plant Echinacea purpurea and is native to the United States. Echinacea is believed to have immunostimulant properties, meaning it can stimulate the immune system, thereby helping to prevent and accelerate the healing of upper respiratory tract infections. Several studies have shown that the use of Echinacea can reduce the duration and severity of ARI symptoms, as well as reduce the risk of recurrent infections. However, research findings on the effectiveness and safety of Echinacea continue to show significant variation. Some clinical trials report significant benefits, while others find no significant effect compared to placebo. Therefore, a systematic review aims to gather the latest evidence regarding the effectiveness and safety of Echinacea in the treatment and prevention of acute respiratory infections (ARI). This approach is expected to yield stronger and more reliable conclusions to support the use of Echinacea as a safe and effective alternative therapy.

Butterfly pea (Clitoria ternatea L.) is a type of ornamental plant characterized by flowers in shades of purple, blue, pink, and white. Besides being an ornamental plant, butterfly pea is also commonly used in traditional medicine. Several previous studies have confirmed its health benefits. Therefore, it is necessary to conduct phytochemical screening for flavonoids, saponins, and alkaloids using the Wilstater method, foam test, Dragendorff’s reagent, and Wagner's test. This study demonstrates the presence of flavonoid, saponin, and alkaloid compounds in butterfly pea flowers, indicated by positive results in various tests conducted.

Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal diseases, characterized by recurrent and painful ulcerations of the mobile or non-keratinized oral mucosa. These lesions are often found on the tongue, labial, and buccal mucosa. Clinically, RAS is divided into three types: minor, major, and herpetiform. The minor type is the most common and has smaller lesions, while the major type has larger lesions and often leaves scars. The herpetiform type is characterized by numerous small lesions appearing simultaneously. Factors influencing the immunological response in RAS include genetic predisposition, viral and bacterial infections, food allergies, vitamin and microelement deficiencies, systemic diseases, stress, and hormonal disorders. Several studies have shown that these factors can trigger or worsen the occurrence of RAS lesions. In addition, emotional and physical stress can contribute to increasing the frequency or duration of ulceration. A 36-year-old female patient presented with pain on the inside of the lower lip that had lasted for 10 days. An intraoral examination revealed a unilateral, yellowish-white ulcer on the inner lower lip surrounded by a distinct, reddish erythema. The lesion was approximately 2-3 mm in size, single in size, soft in consistency, and symptomatic. Based on these findings, the treatment plan includes a complete blood count (CBC), which measures various blood components, including red blood cells, white blood cells, and platelets. This examination is necessary to obtain further information regarding the cause of RAS in this patient. RAS is a multifactorial lesion that can occur in the oral mucosa. Supportive tests such as a complete blood count (CBC) are very useful in establishing the diagnosis and providing further guidance in planning appropriate therapy. Appropriate medication is expected to help the patient recover from complaints and prevent recurrence.   Keywords : Recurrent Apthous Stomatitis, Laboratory, Stress

Mochi-based food products are increasingly popular in Indonesia due to their chewy texture and distinctive sweet taste, making them a popular snack among various groups. As consumer interest in mochi increases, innovation in the production process is crucial, particularly in the selection of liquid ingredients as one of the main components. The use of different liquids has the potential to affect the organoleptic characteristics of mochi, such as color, aroma, texture, and taste, thereby increasing the product's appeal and selling value. This study aims to analyze the effect of the type of liquid used on the organoleptic quality of mochi. The study was conducted using a quantitative approach through an experimental method using a one-factor completely randomized design (CRD) with three replications. The study sample consisted of 30 untrained panelists selected through a total sampling technique from among students of the Culinary Arts Study Program, Padang State University. The four types of liquids used for treatment were water, soy milk, coconut milk, and coconut water. Assessment was carried out using an organoleptic test with a 7-point hedonic scale, covering five aspects: color, aroma, texture, taste, and overall acceptability. Data were analyzed using a one-way ANOVA test to determine the significance of differences between treatments. The results showed that mochi with coconut water scored the highest in color (5.88), texture (6.39), flavor (6.07), and overall acceptability (5.88), while the highest aroma was obtained from mochi with soy milk (6.50). Although statistical results showed no significant difference between treatments (p > 0.05), mochi with coconut water was subjectively preferred by panelists. Therefore, coconut water is recommended as an alternative liquid ingredient that has the potential to improve mochi sensory. Therefore, coconut water is recommended as an alternative liquid ingredient that has the potential to enhance the sensory qualities of mochi.

UD. Indokarya Brass is a company engaged in the brass handicraft industry with its main products being door handles and bells. The main raw materials used in the production process include brass, copper, tin, and aluminum, which are obtained from suppliers both within and outside the city. On average, raw materials are received weekly with quantities of 50–100 kg of brass, 7–10 kg of copper, 10–15 kg of tin, and 3–5 kg of aluminum. In addition, the company also uses additional materials in the form of thinner and epoxy purchased from nearby hardware stores with less frequent purchases, namely 5–10 liters of thinner every month and around 5 kg of epoxy every two months. To date, the company has not had a structured policy for procurement and control of raw material inventory. This condition results in excess inventory of several types of raw materials which actually incurs high costs, both in terms of storage costs and warehouse maintenance costs. This excess inventory ultimately has an impact on reduced efficiency and decreased company profits. This study was conducted to analyze the existing inventory system and compare the company's current policy with a proposed method for more optimal inventory control. The calculation results show that the proposed method is able to provide significant inventory cost savings, namely 83.25% in brass raw materials, 15.28% in copper, 14.6% in tin, 43.37% in aluminum, 4.66% in epoxy, 4.2% in thinner, and 40.7% in other raw materials. Thus, the implementation of the right inventory control method can improve operational efficiency and help companies reduce cost burdens, so that profits can be more optimal.

The high mortality and morbidity rates of infants in Indonesia remain a serious public health problem. One of the main causes of this condition is the emergence of infectious diseases that can actually be prevented through basic immunization. Diseases such as diphtheria, pertussis, tetanus, tuberculosis, poliomyelitis, measles, and hepatitis B are types of diseases that can be prevented by immunization, yet many children still have not received complete immunizations. This study was conducted to determine the relationship between maternal knowledge levels and the completeness of basic immunization status of children aged 12–24 months in RW 13 Kp. Sapan, Sumbersari Village. This study used a quantitative approach with a cross-sectional design and was conducted in August 2024. A total of 39 mothers with children aged 12–24 months became the study respondents through a total sampling technique. Data collection was carried out using a questionnaire, and the data obtained were analyzed using the Chi-square test. The results showed that the majority of mothers had a sufficient level of knowledge, namely 21 mothers (53.8%). In addition, the majority of toddlers, 28 children (71.85%), had received complete basic immunizations. The results of statistical analysis showed a significant relationship between maternal knowledge and the completeness of children's basic immunizations with a p value of 0.006 (p < 0.05). This indicates that the higher the mother's knowledge regarding the importance of immunization, the greater the likelihood of the child receiving complete basic immunizations. Therefore, it is important for mothers to continue to increase their knowledge about immunizations through various sources of information such as books, counseling, or consultations with health workers, so that efforts to prevent infectious diseases in children can be optimally achieved.

This community service activity was carried out with the primary objective of improving the Qur'an reading skills of the women of the Majelis Taklim (Islamic study group) through systematically designed intensive training. Reading the Qur'an properly and correctly is an obligation for every Muslim, but in reality, many people, especially the women of the Majelis Taklim (Islamic study group), still face obstacles in aspects of makhraj, tajwid, and fluency. This condition encourages the need for a targeted coaching program to improve the quality of Qur'an reading, so that the values ​​of Islamic teachings can be understood and practiced more accurately. The training was held in early July 2025 with a total of 35 participants from the Majelis Taklim (Islamic study group) with diverse reading ability backgrounds. The methods used included lectures, demonstrations, reading practice, individual guidance, and ongoing evaluation at each meeting. This approach was chosen so that participants not only gain theoretical knowledge but also practical skills that can be immediately applied. Evaluation was carried out through observing reading ability, courage to ask questions, and active participation in group exercises. The results of the activity showed a significant improvement in the participants' Qur'an reading skills, both in terms of letter pronunciation, application of Tajweed rules, and fluency in reading holy verses. The participants' enthusiasm was evident in their eagerness to participate in all sessions, their sincerity in practicing, and their active interaction during the learning process. Furthermore, this activity also fostered new motivation for participants to continue improving their reading quality independently and create a conducive learning environment in the Islamic study groups. Thus, this training proves that the right learning strategy, supported by high motivation from participants, can have a positive and sustainable impact on improving the quality of Quran reading. It is hoped that this type of program can be replicated in other Islamic study groups so that its benefits are even broader for the community.

The Titanic drama contains many figurative expressions that reflect deep emotions, life values, and internal conflicts. These figures of speech are used to describe love, fear, sadness, and hope in a more vivid and memorable way. The emotional experiences of the characters, especially Jack and Rose, are shown not only through direct dialogues but also through creative figurative language. This study aims to examine the types of figures of speech found in Titanic, a drama film directed by James Cameron. Using a qualitative descriptive method, this study analyzes the film's dialogues based on the conceptual figurative theory proposed by Lakoff and Johnson. This study identified three main types of figures of speech: structural, ontological (including personification and metonymy), and orientational figures of speech. The results showed that structural figures of speech were the most dominant type, appearing in 45.9% of the total data, followed by ontological figures of speech at 29.7%, and orientational figures of speech at 24.3%. This finding proves that figures of speech are not only used to beautify language but also to express feelings and views on life in a deeper and more emotional way. The allusions in Titanic help the audience understand the characters' thoughts and experiences better.

Negotiation is the most fundamental form of Alternative Dispute Resolution (ADR), emphasizing the peaceful settlement of conflicts through direct dialogue between disputing parties without involving a third party. In Indonesia, negotiation has become one of the most widely used ADR mechanisms and has developed across various fields, including civil law, labor relations, administrative disputes, and environmental issues. This study aims to analyze negotiation as an ADR forum from two main perspectives. First, a theoretical review that examines the principles of negotiation, its stages, as well as its advantages and limitations compared to other dispute resolution mechanisms. Second, a practical review that elaborates on the implementation of negotiation within the Indonesian legal context through case studies of disputes resolved through negotiation. The research employs a normative-juridical approach to analyze the legal foundations and principles governing negotiation, combined with an empirical review through case data exploration and interviews with legal practitioners. The findings indicate that negotiation offers several advantages, including efficiency in time and cost, procedural flexibility, and the potential for mutually beneficial solutions (win–win solutions). However, this study also identifies challenges such as unequal bargaining positions between parties, limited legal recognition of negotiation outcomes, and the insufficient capacity of negotiators or informal mediators to fully grasp legal aspects. Based on these findings, the study recommends several strategic steps: enhancing legal recognition and protection for negotiation outcomes, strengthening the capacity and competence of negotiators through legal and communication skills training, and expanding the use of negotiation as an initial step in resolving various types of disputes. With stronger legal frameworks and improved human resources, negotiation has the potential to become a more effective, efficient, and sustainable dispute resolution instrument in Indonesia.

This article aims to examine in depth the implementation of moral values in Islamic educational institutions as a strategic step in shaping students who are not only intellectually intelligent, but also excel morally and spiritually. This research uses a qualitative approach with a library study type, through analysis of Islamic literature, articles on moral education, and relevant research results that discuss moral values. The results of the study indicate that the implementation of moral values in Islamic education includes three main aspects. First, morals towards Allah, including instilling piety, sincerity, and obedience through worship, spiritual habits, and strengthening religious ethics. Second, morals towards fellow human beings, which are realized by fostering honesty, justice, tolerance, empathy, and social responsibility through daily interactions, cooperation, and social activities. Third, morals towards nature, which includes instilling an attitude of love for the environment, preserving God's creation, and building ecological awareness as part of a Muslim's moral responsibility. Strategies for implementing moral values include integrating values into all subjects, providing role models by teachers and other educational staff, fostering positive behavior within the school environment, and continuously evaluating student attitudes and behavior. This strategy is designed to instill moral values not only at the cognitive level but also as concrete habits in daily life. This article's contribution lies in developing a conceptual and practical framework for building an Islamic education system oriented toward holistic character formation. With this approach, moral values are expected to be thoroughly internalized in students' personal, social, and environmental lives.  

This study aims to analyze the implementation of the fruit receiving and storage process in the cold kitchen section at PT. Aerofood Indonesia (ACS) Surabaya, which is one of the important units in the raw material supply chain in the aviation catering industry. The study used a qualitative descriptive method with data collection techniques through in-depth interviews, direct field observations, and documentation of work procedures. Informants in the study consisted of the Cold Kitchen Supervisor and two staff members who directly handle the fruit receiving and storage activities. The results showed that the fruit receiving process was carried out through three main stages, namely checking documents (delivery orders and purchase orders), physical inspection of the fruit such as color, texture, and aroma, and recording the details of the receipt into a special form. This inspection is important to ensure that the fruit received is in a condition suitable for consumption and in accordance with the established specifications. During the storage stage, the fruit is arranged according to type and level of durability. Small fruits such as strawberries or grapes are stored at a temperature of 0–6°C, while large fruits such as watermelons and melons are stored at a temperature of 18–21°C. This arrangement aims to maintain freshness and extend shelf life. In addition, the FIFO (First In, First Out) system is consistently implemented to prevent the accumulation of old stock that can reduce quality. Storage room temperature monitoring is carried out every 4 hours to ensure temperature stability according to standards. Overall, the implementation of the fruit receiving and storage process at ACS Surabaya has met the principles of good raw material management (Good Reception & Storage Practice). This implementation procedure supports the achievement of quality and food safety standards in flight catering services, which are highly dependent on the timeliness and quality of ingredients.

This study aims to describe the effect of the cooperative learning model of the Teams Games Tournament (TGT) type on the learning outcomes of fifth-grade elementary school students. The research method used was experimental with a quasi-experimental approach. The research design employed was a non-equivalent control group design. The study involved two classes: the experimental class (VA), which was taught using the Teams Games Tournament (TGT) cooperative learning model, and the control class (VB), which was taught without using the TGT model. The sample consisted of 50 students from classes VA and VB at SD YPI Darussalam. The data collection technique used was a learning outcomes test, designed to measure students’ mastery of the learning material. Data analysis was conducted using the Independent Sample T-test to determine differences in learning outcomes between the two groups. The analysis results showed a Sig. (2-tailed) value of 0.000 ≤ 0.05, which is less than the significance threshold of 0.05. Therefore, H₀ was rejected and Hₐ was accepted, indicating that the cooperative learning model of the Teams Games Tournament (TGT) type has a significant effect on students’ learning outcomes. The findings of this study highlight that the TGT model can create an engaging and competitive learning atmosphere, enhancing student participation and motivation in the learning process. Furthermore, the structured stages in the TGT model—comprising presentation, group formation, game sessions, and tournaments—allow students to interact more actively, share knowledge, and strengthen their understanding of the material collaboratively. Thus, the implementation of the Teams Games Tournament (TGT) cooperative learning model is recommended as an effective alternative strategy for improving learning outcomes in elementary schools, especially for fifth-grade students.

The production of pharmaceutical sterile products requires strict procedures to minimize the risk of microbial, particulate and pyrogen contamination that can be harmful to the user's health. The selection of the right sterilization method is the key to achieving the desired stability of the final product. Filtration sterilization is one of the oldest methods used for pharmaceutical sterile products. There are two types of feed flow in the method, namely through flow filtration and tangential flow filtration. This review article is prepared through literature search and download of national or international journals with inclusion or exclusion criteria that have been set. Literature sources are accessed online from various sites such as Google Scholar and Pubmed in the range of 2014-2024. The keywords used for journal searches are sterilization, through flow filtration, and tangential flow filtration. This review article reviews and compares the two methods to understand the differences, mechanism of action, and research objectives based on the review article on membrane filtration sterilization. This review aims to provide a better insight into the advantages and disadvantages of each membrane filtration sterilization method, as well as guidance in choosing the appropriate method based on the characteristics of the product to be sterilized. The results showed that through flow filtration is more commonly used in small volume and batch processes because of its simple design, but has limitations in reducing membrane fouling. In contrast, tangential flow filtration allows for continuous processing of larger volumes, with the advantage of minimizing particle build-up on the membrane surface, thus extending membrane life. The choice of method is also influenced by factors such as particle size, viscosity of the solution, sensitivity to heat, as well as operating costs. An in-depth understanding of the Working Principle and application of each method is essential for the pharmaceutical industry to ensure the quality, safety and efficiency of the production process. Thus, this review is expected to be a reference for researchers and practitioners in determining the optimal filtration sterilization strategy according to product needs.

Bekasam is a traditional fermented fish product commonly produced in South Sumatra and South Kalimantan, known for its distinctive sour taste resulting from the metabolic activity of lactic acid bacteria (LAB). LAB play a crucial role in the fermentation process, contributing to the product’s flavor, texture, and safety. This study aimed to isolate, identify, and characterize LAB from bekasam made using tilapia (Oreochromis niloticus). Isolation of bacterial strains was performed using the pour plate method on Nutrient Agar (NA) medium at various serial dilutions to obtain discrete colonies. The colonies were observed macroscopically to assess their morphological characteristics, including shape, size, color, surface texture, and edge profile. Further identification involved Gram staining to determine cell wall type and microscopic morphology. The results revealed that the bacterial colonies were generally small, round, white to cream in color, with smooth surfaces and flat edges. Gram staining demonstrated that the dominant isolates were Gram-positive bacteria, exhibiting rod-shaped or oval morphology. These characteristics are consistent with members of the genus Lactobacillus sp., a common LAB group in fermented fish products. Additional phenotypic traits observed included catalase-negative reactions, absence of spore formation, and the ability to produce lactic acid as the main metabolic end product. The combination of morphological, staining, and basic biochemical characteristics supports the initial identification of the isolates as LAB. The presence of Lactobacillus sp. in bekasam suggests their significant contribution to the fermentation process, influencing the product’s sourness, safety, and preservation. The findings of this study provide a basis for further molecular characterization and potential selection of LAB strains as starter cultures to improve the quality, consistency, and safety of bekasam in traditional and industrial production.

Batam City, as an industrial hub in the Riau Islands Province, plays a vital role in the region’s economic growth. However, a surge in inflation can affect investment interest, as investors tend to avoid areas with economic uncertainty. One of the main contributors to inflation in Batam is the food component, which experiences high demand, especially during certain periods such as religious holidays and the arrival of international tourists. Batam, which is not a food-producing area, faces significant challenges in meeting agricultural needs and currently remains dependent on supplies from outside the region. Geographic constraints, such as inefficient logistics, weather disruptions, and institutional weaknesses in the food sector, further aggravate inflation control efforts. In addition, hilly terrain and less fertile land limit the types of crops that can be cultivated, making food price stability critically important. This study aims to evaluate the effectiveness of the Low-Cost Market Operation Team Program (Tim Operasi Pasar Murah) in Batam City in 2024. The method used is Sequential Explanatory Design with a mixed-methods approach. Quantitative findings indicate that the average success rate of the program is 85.93%, with a target achievement rate of 90.12% and a satisfaction level of 86.11%. Qualitative results suggest that the policy of conducting low-cost market operations has been appropriate and carried out by authorized institutions, with strong collaboration between the government and the private sector. The program has succeeded in maintaining price stability ahead of the fasting month and Eid al-Fitr, receiving positive responses from the community and demonstrating good internal coordination. In conclusion, the low-cost market operation program in Batam City has been effective in curbing inflation before the fasting month and Eid al-Fitr. However, for comprehensive inflation control, relying solely on this program is insufficient. Additional strategies are needed to ensure sustainable food price stability.
