This study aims to analyze implementation of digital advertising licensing in Yogyakarta City based on Regional Regulation Number 6 of 2022 and to identify challenges faced in the process. Research employs a normative juridical approach with qualitative methods. Legislative approach examines regulations such as the 1945 Constitution, Law No. 1 of 2024 on Electronic Information and Transactions, Regional Regulation No. 6 of 2022, while the conceptual approach analyzes authority, supervision, legal compliance. Bahan hukum were collected through interviews, observations, document studies, analyzed qualitatively via bahan hukum reduction, narrative presentation, conclusion drawing. The findings indicate digital advertising licensing in Yogyakarta City has a robust legal foundation, but implementation is hindered by low compliance among business actors (31.9% of digital advertisements were unlicensed in 2024), complex procedures, and inadequate coordination among agencies such as DPMPTSP, BPKAD, and Satpol PP. Key challenges include unclear technical regulations, overlapping authorities, limited monitoring technology, and low legal awareness among business actors due to high licensing costs. Study recommends revising Regional Regulation, digitizing licensing system through OSS, strengthening inter-agency coordination, conducting socialization programs to enhance compliance, thereby supporting orderliness, city aesthetics, increased local revenue, legal certainty. These measures can strengthen Yogyakarta’s efficient and harmonious digital advertising governance.

The problem of organic waste remains a serious issue in Indonesia, including in rural areas. Jatitamban Village, Bondowoso Regency, faces similar challenges due to household waste and residual by-products from local small enterprises producing tape and cassava chips, which are not yet optimally managed. The Community Service Program (KKN) of the University of Jember implemented an initiative to empower village youth through maggot cultivation as an environmentally friendly and economically valuable solution for organic waste management. This study employed a Community-Based Research (CBR) approach by engaging local youth as active partners in every stage of the program, including observation, planning, socialization, technical training, workshops, and monitoring. The results indicate that Black Soldier Fly (BSF) maggot cultivation serves as an effective strategy to reduce the volume of organic waste while producing value-added products such as alternative animal feed and organic fertilizer. The involvement of youth not only enhanced their knowledge and skills but also fostered environmental awareness and created new entrepreneurial opportunities. Furthermore, the program successfully established a solid and independent youth group capable of sustainably managing organic waste through maggot cultivation practices. The implications of this program extend beyond environmental improvement to promoting village economic independence through the utilization of organic waste. Therefore, youth empowerment through maggot cultivation can serve as a strategic model for sustainable waste management as well as strengthening community capacity in rural areas.

This study aims to analyze the role of communication in Customer Relationship Management (CRM) systems in creating customer satisfaction at PT Bangkit Jaya Teknik Indonesia, a business-to-business (B2B) cold storage installation service company. The research background lies in the increasing number of customer complaints during 2022–2024, mainly due to delayed responses, suboptimal after-sales service, and the absence of a centralized communication record system. This study employed a qualitative approach with a case study design. Data were collected through observation, semi-structured interviews with internal parties (marketing project, project manager, project PIC) and customers, as well as company archival documentation. The findings reveal that responsive, open, and two-way communication plays a significant role in enhancing customers’ sense of being valued, trust, and loyalty, which ultimately fosters satisfaction. However, communication barriers such as delays in after-sales service, gaps between customer expectations and company procedures, and the lack of a communication database remain major challenges. To overcome these, the company has initiated strategies including the development of a customer communication database, improved after-sales monitoring, and the adjustment of communication standard operating procedures to align with customer needs. These results reinforce the relevance of Relationship Management theory and the IDIC model, both of which emphasize communication as the core of CRM. Theoretically, this study contributes to organizational communication studies, while practically, it provides recommendations for B2B service companies to prioritize communication in CRM strategies to strengthen customer satisfaction and loyalty.

The DH Building of the Electrical Engineering Study Program at Udayana University faces significant challenges in energy efficiency, as it still relies on conventional electrical systems. User negligence, such as forgetting to switch off lights and air conditioners (AC) after use, often results in unnecessary energy waste and increased operational costs. This issue highlights the urgent need for smart solutions capable of automating energy management, reducing waste caused by human error, and supporting the creation of a more efficient and sustainable campus environment. To address this problem, this study designs and implements a smart building system based on the Internet of Things (IoT). The system employs a NodeMCU ESP32 microcontroller as the main processing unit, integrated with a series of sensors including a DHT22 sensor for monitoring temperature and humidity, an MQ2 sensor for smoke detection, a PIR sensor for motion detection, and a PZEM-004T sensor for monitoring energy consumption. Control of electronic devices such as lights and AC units is carried out both automatically and manually through relay modules connected to the system. All sensor data and control functions are accessed via a web interface developed using the Laravel framework and a MySQL database. The testing results indicate that the designed system was successfully implemented and functions as expected. Sensor testing demonstrated high accuracy compared to standard measuring instruments, while the electronic device control system achieved an average response time of approximately 3.6 seconds, proving its reliability. Overall, the system provides a comprehensive solution for energy consumption monitoring and control, while also enhancing comfort and safety in the DH Building, in line with the goals of energy efficiency and facility modernization.

The integration of Internet of Things (IoT) with cloud computing has revolutionized healthcare systems, offering scalable and real-time patient monitoring. However, optimizing response times and energy consumption remains crucial for efficient healthcare delivery. This research evaluates various algorithmic approaches for workload migration and resource management within IoT cloud-based healthcare systems. The performance of the implemented algorithm in this research, Hybrid Dynamic Programming and Long Short-Term Memory (Hybrid DP+LSTM), was analyzed against other six key algorithms, namely Gradient Optimization with Back Propagation to Input (GOBI), Deep Reinforcement Learning (DRL), improved GOBI (GOBI2), Predictive Offloading for Network Devices (POND), Mixed Integer Linear Programming (MILP), and Genetic Algorithm (GA) based on their average response time and energy consumption. Hybrid DP+LSTM achieves the lowest response time (82.91ms) with an energy consumption of 2,835,048 joules per container. The outcome of the analysis showed that Hybrid DP+LSTM have significant response times improvement, with percentage increases of 89.3%, 79.0%, 83.8%, 97.0%, 99.8%, and 99.94% against GOBI, GOBI2, DRL, POND, MILP, and GA, respectively. In terms of energy consumption, Hybrid DP+LSTM outperforms other approaches, with GOBI2 (3,664,337 joules) consuming 29.3% more energy, DRL (2,973,238 joules) consuming 4.9% more, GOBI (4,463,010 joules) consuming 57.4% more, POND (3,310,966 joules) consuming 16.8% more, MILP (3,005,498 joules) consuming 6.0% more, and the GA (3,959,935 joules) consuming 39.7% more. The result of ablation of the Hybrid DP+LSTM model achieves a 47.05% improvement over DP-only (156.57ms) and a 70.64% improvement over LSTM-only (282.41ms) in response time. On the energy efficiency side, Hybrid DP+LSTM shows 22.80% improvement over LSTM-only (3,671,51 joules), but 7.34% underperformance compared to DP-only (2,640,93). These research findings indicate that the Hybrid DP+LSTM technique provides the best trade-off between response time and energy efficiency. Future research should further explore hybrid approaches to optimize these metrics in IoT cloud-based healthcare systems.

The banana chip business in Ledokombo Village, Jember Regency, is one of the sources of livelihood for the local community. However, increasingly fierce business competition has led to a decrease in demand and has an impact on declining turnover of MSME actors. Marketing that is still conventional is one of the factors limiting product reach. This community service activity aims to increase the marketing capacity of MSME actors through digital marketing training. The training was carried out for four weeks with stages: problem analysis, provision of branding and digital marketing materials, assistance in making packaging labels, marketplace accounts (Shopee) and social media (Instagram), as well as monitoring and evaluation. The results of the activity show that MSME actors understand the importance of digital marketing strategies, are able to create "The King" product packaging labels, and have Shopee and Instagram accounts that are actively used for online sales. Business actors are also getting used to operating digital application features that support the marketing process. This activity has a positive impact on increasing product attractiveness and expanding consumer reach. Thus, digital marketing training has proven to be effective as an innovative solution in facing MSME marketing challenges, as well as being a model for local economic empowerment that can be replicated in other regions with similar characteristics.

Hypertension is one of the most common non-communicable diseases, with a high incidence rate that has become a major global health concern. It is often referred to as a “silent killer” because many patients are unaware of their condition until serious complications arise. In Indonesia, the prevalence of hypertension is relatively high, yet many sufferers remain undiagnosed or do not receive proper medical treatment. Several risk factors contribute to hypertension, including age, heredity, high-salt diet, obesity, lack of physical activity, and unhealthy lifestyles such as smoking and alcohol consumption. Without proper management, hypertension may lead to severe complications such as stroke, heart failure, and chronic kidney disease. Management of hypertension generally involves pharmacological therapy, such as the administration of antihypertensive drugs, as well as non-pharmacological interventions through lifestyle modifications. Nurses play a crucial role in patient education, monitoring, and preventing complications through comprehensive nursing care. The purpose of this study is to describe the nursing care provided to Mr. R, who experienced a cardiovascular system disorder, namely hypertension, in the Dahlia Ward of RSUD dr. Soeselo, Tegal Regency. The research method used was descriptive with a case study approach, allowing for a systematic and clear presentation of the patient’s condition. The case findings showed that the patient’s main complaint was a headache radiating to the nape of the neck. Based on nursing assessment, two nursing diagnoses were identified: acute pain and lack of knowledge regarding the disease and its management. Interventions were determined using national standards such as SDKI, SLKI, and SIKI, which are expected to reduce symptoms and improve the patient’s understanding of hypertension.

The Mosque Youth Organization (REMAS) plays an important and strategic role as an agent of social and religious change among the younger generation. This study aims to improve the governance of the Mosque Youth Organization in Blitar City to be more professional and Islamic through the synergy of public administration and Islamic values. The main problems faced include a lack of coordination with the mosque administrators, a lack of effective leadership, and low community participation, which are influenced by internal factors such as the busyness of members and external factors such as limited funds and facilities. The method used is a participatory approach through needs analysis with 20 REMAS and mosque administrators, followed by training on professional Islamic governance, management skills, and evaluation assistance for its implementation. The training was held at the Al Mugi Barokah Mosque in Blitar City in September 2025, in collaboration with the Indonesian Mosque Youth Communication Agency (BKPRMI) as a stakeholder. The results of the community service showed significant improvements, namely the formation of a clear organizational structure, community-based work programs such as skills training and innovative social activities, and effective coordination with mosque administrators through regular forums to increase community participation. This approach integrates good governance principles such as transparency, accountability, and documentation using Trello or Google Sheets with Islamic values such as deliberation, trustworthiness, benevolence, and the example set by the Prophet Muhammad SAW. These activities contribute to sustainable social transformation among mosque youth, strengthening their role as agents of socio-religious change, although challenges such as limited resources, internal conflicts, and slow technological adaptation still need to be addressed through regular monitoring and further technological integration.

Based on the results of initial interviews and observations, it was found that several students still experienced difficulties in writing procedural texts effectively. These difficulties included a lack of understanding of the structure and characteristics of procedural texts, challenges in expressing ideas in written form, limited ability to compose coherent and communicative sentences, and the use of monotonous learning models that failed to stimulate student motivation. This study aims to describe the implementation of the Project Based Learning (PjBL) model based on the Tri N approach (Niteni, Niroke, and Nambahake) to improve the procedural text writing skills of fourth-grade students at Sidomukti Elementary School, Ambal Sub-district, Kebumen Regency, as well as to identify the improvement in writing skills after its application. The research employed a descriptive qualitative method with data collection techniques including observation, tests, and documentation. Data analysis was conducted through the stages of data reduction, data display, and conclusion drawing. The findings revealed that the application of the PjBL model integrated with Tri N values significantly improved students’ ability to write procedural texts. The learning process was carried out through six main stages of PjBL: formulating essential questions, planning projects, creating schedules, monitoring student activities, testing results, and evaluating learning experiences. The integration with Tri N principles encouraged students to understand, imitate, and develop their writing skills gradually. Thus, the PjBL model based on Tri N proved effective in helping students overcome writing difficulties while also fostering creativity, independence, and active participation in the learning process.

Background: Pregnant women with poor nutritional status are at risk of experiencing low breast milk production, which in turn can affect the fulfillment of infant nutrition from an early age. Suboptimal breast milk production impacts the growth and development of infants and has the potential to increase the incidence of malnutrition. Based on preliminary data in the Siti Hajar Room of Sultan Hadlirin Islamic Hospital, Jepara, it was found that several postpartum mothers experienced delayed breast milk production with a history of malnutrition. This condition shows the importance of maternal nutritional status during pregnancy as a factor that directly influences lactation. Objective: This study aims to determine the relationship between the nutritional status of pregnant women and postpartum breast milk production in the Siti Hajar Room of Sultan Hadlirin Islamic Hospital, Jepara. Method: The study used a cross-sectional design with a total sampling technique. A total of 30 postpartum mothers were selected as respondents. The independent variable consisted of the nutritional status of pregnant women as measured by Body Mass Index (BMI), Upper Arm Circumference (LILA), and hemoglobin (Hb) levels. The dependent variable was postpartum breast milk production as observed clinically. Data analysis was performed using the Chi-Square test with a significance level of p < 0.05. Results: The results of the study showed a significant relationship between the nutritional status of pregnant women and breast milk production. Statistical tests found that BMI (p = 0.018), LiLA (p = 0.027), and Hb levels (p = 0.006) had a significant association with the adequacy of breast milk production. Conclusion: The nutritional status of pregnant women was proven to be closely related to postpartum breast milk production. Mothers with good nutritional status tend to produce sufficient breast milk production. This finding emphasizes the need for routine nutritional monitoring of pregnant women and nutritional education during pregnancy to support the success of exclusive breastfeeding.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder whose prevalence continues to rise, making it a major challenge for health systems worldwide. This disease results from a combination of insulin resistance and impaired pancreatic β-cell function, leading to persistent hyperglycemia and increased risk of long-term complications affecting the kidneys, cardiovascular system, nervous system, and eyes. This report describes the case of a 52-year-old woman diagnosed with T2DM for approximately ten years. The patient presented with fatigue, nocturnal polyuria, nausea after meals, significant weight loss, and tingling in her extremities. Laboratory findings revealed an HbA1c level of 12%, reflecting very poor glycemic control. A family medicine approach was applied through detailed history taking, physical and laboratory examinations, home visits, and completion of a family folder to assess clinical, personal, social, and functional aspects. Interventions included counseling on balanced diet, encouragement of regular physical activity, education on diabetic foot care, and pharmacological treatment with metformin and insulin. The family received counseling about hereditary risk factors, the importance of emotional support, and the need for consistent monitoring of health status. The patient was still capable of light daily activities, supported by a highly functional family environment with an APGAR score of 10. A holistic family medicine–based approach was shown to improve treatment adherence, patient knowledge, and overall quality of life. Therefore, management of T2DM requires a comprehensive strategy that integrates promotive, preventive, curative, and rehabilitative components, emphasizing the active involvement of family and community at the primary care level to reduce complications, slow disease progression, and enhance patient well-being.   Keywords: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder whose prevalence continues to rise, making it a major challenge for health systems worldwide.

A partnership agreement is a form of business collaboration, either directly or indirectly, that is established based on the principles of mutual need, mutual trust, mutual reinforcement, and mutual benefit. Such partnerships generally involve Micro, Small, and Medium Enterprises (MSMEs) working with larger businesses in order to create a fairer and more sustainable business relationship. However, in practice, the implementation of partnership agreements often does not reflect these fundamental principles. This is also evident in the nucleus-plasma scheme within the palm oil plantation sector, where the relationship between the nucleus companies and plasma farmers tends to show an imbalance of bargaining power. This study aims to examine the application of partnership principles in the implementation of nucleus-plasma agreements in palm oil plantations, viewed from the perspective of prevailing legislation, particularly the Law on Micro, Small, and Medium Enterprises (MSME Law). The findings indicate that the application of partnership principles has not yet been fully implemented consistently. The partnership relationship remains unequal and is largely dominated by the nucleus companies, creating a sense of injustice for plasma farmers. In terms of supervision, the Indonesian Business Competition Supervisory Commission (KPPU) plays a crucial role in ensuring that partnership agreements are carried out in line with these principles. One of the measures taken is monitoring the implementation of behavioral change commitments by business actors. KPPU ensures that nucleus companies do not abuse their dominant position and continue to provide fair opportunities for plasma farmers. Therefore, this study highlights the importance of strengthening oversight and enforcing regulations so that the objectives of nucleus-plasma partnerships in palm oil plantations can truly be realized in accordance with the principles mandated by law.

The Student Evaluation of Lecturers (EDOM) at the Faculty of Engineering, Universitas Dr. Soetomo has historically been conducted via Google Forms and processed manually, resulting in slow response times, repetitive recap procedures, and insufficiently documented reporting validity. This study aims to design, build, and evaluate a web-based EDOM system using the Prototype Model (MODEL PROTOTYPE) to improve data collection efficiency, recap accuracy, and the effectiveness of feedback for teaching quality assurance. The development method comprises requirements elicitation with the Quality Assurance Unit through a review of SPMI documents and brief interviews, architectural and interface design (Laravel, MVC pattern, and MySQL), staged prototyping, and rapid iterations based on stakeholder feedback until functional conformity is achieved. The resulting system provides authentication and role-based authorization (Admin, GPM, Lecturer, Student), odd/even period management, a question bank employing a Likert scale, anonymous questionnaire submission, score recap per lecturer and per category (pedagogical, professional, personal, social), dashboard visualizations, and report export to support governance needs. Functional evaluation was conducted through black-box testing on core scenarios (login, period scheduling, submission, recap, and export) and indicated conformance to specifications. User acceptance evaluation employed the Technology Acceptance Model (TAM) to examine perceived usefulness, perceived ease of use, attitude toward use, and behavioral intention; the results indicate positive acceptance and potential for operational adoption. Practically, the prototype approach accelerates requirement alignment, reduces the risk of mis-specification, and facilitates change control, while the Laravel-based implementation supports maintainability, role-based access security, and further feature development. The study is limited to a single faculty; future work may include SSO integration, audit trails, and longitudinal, cross-semester analytics for more comprehensive monitoring of lecturer performance.

In the Candi Village community, there is still a phenomenon of a lack of awareness in understanding, exploring, and experiencing the historical values contained in Gedong Songo Temple. This condition has implications for the less than optimal use of historical sites as educational facilities and media for forming local cultural identity. Efforts to increase historical awareness are considered more effective if instilled from an early age through a contextual and applied educational approach. This study focused on students of SDN Candi 03, most of whom come from four hamlets around the area, namely Talun, Nglarangan, Ngipik, and Ndarum. The community service program designed aims to provide solutions to the partner's priority problem, namely low historical awareness among students, through the application of educational tourism and Project Based Learning (PjBL) methods. Educational tourism is positioned as a learning strategy that integrates recreational and educational aspects, allowing students to gain firsthand experience in interpreting historical sites. Meanwhile, PjBL is oriented towards project-based activities that encourage active student involvement in exploring real-world problems and producing creative products or solutions. The program is divided into three main stages: preparation, activity implementation, and monitoring and evaluation. The results of these activities are expected to increase students' knowledge, awareness, and concern for local cultural heritage, while fostering a sense of responsibility in preserving Gedong Songo Temple. Thus, educational tourism and PjBL-based education can be a relevant alternative model for fostering historical awareness among the younger generation in areas surrounding historical sites.

Liver cirrhosis is a chronic disease characterized by progressive fibrosis, altered liver architecture, and the formation of regenerative nodules. Although it develops slowly, cirrhosis often leads to serious complications such as ascites, variceal bleeding, jaundice, and hepatic encephalopathy. According to the Global Burden of Disease Study 2019, cirrhosis is among the leading causes of death worldwide, with more than 1.4 million deaths annually. In Indonesia, the prevalence of cirrhosis is reported at 0.4% (Riskesdas, 2021) and shows an increasing trend over the years. This case study aims to describe the application of comprehensive nursing care in a patient diagnosed with liver cirrhosis using the nursing process approach. The research design was a case study conducted on Mr. R, who was admitted to Dahlia Ward at RSUD dr. Soeselo, Tegal. Data collection was carried out through interviews, observations, physical examinations, and medical record reviews. The results revealed that the main nursing problems identified were ineffective peripheral perfusion, ineffective breathing pattern, and knowledge deficit. Nursing interventions provided included positioning the patient in semi-fowler, monitoring vital signs, educating the patient about low-sodium diet and fluid restriction, and collaborating in the administration of diuretics and albumin. After three days of nursing care, the evaluation indicated clinical improvement, evidenced by reduced edema, decreased shortness of breath, and increased patient understanding of his disease and treatment plan. In conclusion, nursing care with a comprehensive process approach has a significant positive impact on the condition of patients with liver cirrhosis. Nurses play an essential role in assessment, planning, implementation, evaluation, and providing health education to prevent complications and improve patients’ quality of life.

Noise is a physical hazard in the work environment that caan reduce hearing loss, especially in the rubber processing industry. The research aims to describe the noise level and control efforts in the production area of PT. Karet XYZ Palembang City in 2025. This study uses a descriptive design with a cross-sectional approach.  Data were collected through direct noise level measurements using sound level meters at wet and dry production areas by taking 8 measurements and questionnaires on 75 selected purposive sampling workers.  Data analysis was carried out univariately. It shows that most of the measurement points have a noise level above the threshold value of 85 dBA in accordance with the Regulation of the Minister of Health of the Republic of Indonesia Number 70 of 2016. The highest values were recorded in the Hummer Mill engine (89,76 dBA) and the Cooling Tunnel (89,70 dBA). All respondents were exposed to noise for ≥8 hours/day. Noise control has been carried out with administrative techniques and the use of personal protective equipment (PPE) but has not been fully effective from the complaints of 7 workers regarding suboptimal protection. The noise level at PT. Karet XYZ and duration of exposure exceeding threshold values that increase the risk to workers health. It is necessary to increase the effectiveness of noise control with a technical, administrative approach and monitoring the optimal use of personal protective equipment (PPE).

Background: There are still shortcomings in the implementation of a truly safe and optimal thoracic examination protocol for toddlers in certain hospital settings. Furthermore, data related to direct radiation dose measurements and evaluation of the effectiveness of thoracic examination techniques for toddlers specifically in the local context in Indonesia are very limited. Objective: To examine the thoracic examination procedure that can be performed with a high level of safety without compromising the quality of diagnostic results and to evaluate the radiation exposure dose and thoracic examination techniques in toddlers at Hospital. Methodology: This study used a mixed methods approach with a convergent parallel design. Quantitative data were obtained from radiation dose measurements and examination parameters, while qualitative data were collected through observation, interviews, and group discussions, then analyzed thematically to understand the factors that influence radiation dose in infant thoracic examinations. Results: Research on thoracic radiology examinations in toddlers at Heart and Vascular Hospital was conducted systematically and in accordance with established procedures. Some limitations emerged from limited radiation dose records and inconsistent use of protective shields. Efforts to reduce radiation exposure include optimizing examinations, proper collimation, selecting exposure parameters, and educating families and staff. Continuous training and strict implementation of standard operating procedures (SOP) are essential to raise awareness of the ALARA principle. Internal policies and routine oversight are also needed to improve radiation dose monitoring, with the hope of improving the quality of radiology services and optimizing protection for toddler patients.

This study aims to analyze the effect of fishing ground differences between WPPNRI 711 and 712 on squid (Loligo spp) catches using boat-operated falling nets landed at Nusantara Fishing Port Muara Angke, Jakarta. The research employed a quantitative approach with a two-treatment experimental design, involving fishing operations in two different areas with an equal number of trips (six trips each), analyzed using an independent samples t-test. The results indicated no statistically significant difference in catches between WPPNRI 711 and 712 (p = 0.747 > 0.05). However, production data revealed variations in catch differences, with CPUE (Catch Per Unit Effort) in WPP 711 being higher than in WPP 712. These variations are likely influenced by environmental factors, oceanographic conditions, fishing pressure, and squid spawning seasons. The implications of this study highlight that differences in fishing grounds do not always produce significant statistical impacts on catches but remain crucial for sustainable squid fisheries management. Policy recommendations include regulating fishing efforts based on spawning seasons, routine stock monitoring through CPUE, and adopting advanced fishing technologies to enhance efficiency and sustainability. This research provides valuable input for fisheries management and supports sustainable utilization of squid resources at Muara Angke.

Successful pollination in oil palm depends heavily on the availability of Elaeidobius kamerunicus pollinator insects that require anthesis male flowers as habitat and food sources. This study aimed to analyze the relationship between anthesis male flower availability on E. kamerunicus beetle population and its impact on parthenocarpy bunch formation at PT. Graha Inti Jaya, Central Kalimantan. Observational method with descriptive and correlational approaches was conducted on 484.57 hectares of oil palm plants varieties Socfindo and Lonsum planted in 2007-2008 during February-July 2025 period. Data collection included anthesis male flower census, beetle population monitoring using yellow traps, and parthenocarpy bunch analysis from mill sorting. Data analysis used linear regression, Pearson correlation, and two-way ANOVA with 95% confidence level. Results showed significant relationship between anthesis male flower availability and E. kamerunicus beetle population (R² = 0.728, p < 0.05), where each unit increase of anthesis male flower increased beetle population by 2,667 individuals per hectare. However, relationship between beetle population and parthenocarpy bunches was not significant (R² = 0.114, p > 0.05), indicating complexity of pollination factors. Variety and planting year differences showed no significant effect. This study recommends maintaining anthesis male flower availability >5% per hectare for optimal natural pollinator beetle population.
