Lead (Pb²⁺) contamination in wastewater is a major environmental concern due to its toxicity, persistence, and ability to accumulate in living organisms. Adsorption using biomass-based materials has been developed as an alternative treatment method because it is efficient, economical, and environmentally friendly. This study aimed to analyze the effect of bioadsorbent dosage and contact time on Pb²⁺ removal efficiency and evaluate Pb²⁺ mass distribution using mass balance analysis in a batch adsorption system. Ramie leaf (Boehmeria nivea) was utilized as a bioadsorbent due to its lignocellulosic content, which provides active sites for metal ion adsorption. The research was conducted experimentally through bioadsorbent preparation, chemical activation, and batch adsorption using artificial Pb²⁺ solutions with variations in bioadsorbent dosage and contact time. Pb²⁺ concentrations before and after adsorption were analyzed using Atomic Absorption Spectroscopy (AAS). The obtained data were used to determine removal efficiency and Pb²⁺ distribution between the liquid phase and bioadsorbent. The results showed that ramie leaf bioadsorbent effectively reduced Pb²⁺ concentration, with the optimum condition obtained at 4 g/L bioadsorbent dosage and 90 minutes contact time, achieving 98.46% removal efficiency. Mass balance analysis indicated that Pb²⁺ ions were successfully transferred from the solution phase onto the bioadsorbent surface. These findings demonstrate that ramie leaf bioadsorbent has potential as a sustainable alternative material for heavy metal removal in wastewater treatment.

This research is motivated by the importance of implementing Standard Operating Procedures (SOP) in speed boat maintenance activities as a supporting facility for ship agency operations at PT. Sinar Pasific. The high intensity of speed boat usage makes the fleet vulnerable to damage if maintenance is not carried out regularly and according to procedures. Based on initial observations, inconsistencies in maintenance implementation, incomplete documentation, and damage to the engine, electrical systems, and hull were still found, which can disrupt company operations. This study aims to determine the implementation of SOPs, the obstacles encountered, and the efforts made to optimize speed boat maintenance at PT. Sinar Pasific. This research was conducted at PT. Sinar Pasific during the author’s Onboard Practical Training (PRADA) from August 2024 to July 2025. The research method used is a descriptive qualitative method. The data sources were obtained through direct field observation, semi-structured interviews with personnel involved in speed boat operations, and documentation studies related to fleet maintenance activities. The results show that the implementation of Standard Operating Procedures (SOP) in speed boat maintenance at PT. Sinar Pasific has been carried out but has not yet run optimally. This is indicated by inconsistent maintenance schedules, lack of supervision, and incomplete maintenance documentation. In addition, several problems were still found, such as damage to the engine, electrical systems, and speed boat hulls, which can hinder company operations. To overcome these obstacles, the company has made efforts by improving discipline in SOP implementation, conducting regular supervision and evaluation, improving maintenance documentation, and increasing technicians’ understanding of the importance of preventive maintenance so that speed boat conditions are maintained and operational activities run smoothly.

Prasman (Peperomia pellucida) merupakan tanaman obat yang diketahui mengandung berbagai senyawa metabolit sekunder seperti alkaloid, flavonoid, saponin, tanin, dan terpenoid yang berpotensi memiliki aktivitas biologis. Penelitian ini bertujuan untuk mengetahui tingkat toksisitas ekstrak metanol batang prasman terhadap mortalitas larva udang (Artemia salina L.) menggunakan metode Brine Shrimp Lethality Test (BSLT). Penelitian dilakukan secara eksperimental dengan memberikan ekstrak metanol batang prasman pada berbagai konsentrasi, yaitu 10, 100, 500, 1000, 5000, dan 10000 ppm serta kontrol. Parameter yang diamati adalah persentase mortalitas larva setelah 24 jam perlakuan. Data dianalisis menggunakan metode interpolasi dan analisis probit untuk menentukan nilai LC₅₀. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi ekstrak menyebabkan peningkatan mortalitas larva secara bertahap hingga mencapai 100% pada konsentrasi 10.000 ppm. Perhitungan LC₅₀ dengan metode interpolasi menghasilkan nilai 680,2 ppm pada pengujian pertama dan 529,66 ppm pada pengujian duplo. Analisis probit pada pengujian duplo menghasilkan nilai LC₅₀ sebesar 198,97 ppm. Nilai LC₅₀ yang berada di bawah 1000 ppm menunjukkan bahwa ekstrak metanol batang prasman bersifat toksik terhadap larva Artemia salina dengan kategori moderat atau racun sedang. Aktivitas toksik tersebut diduga berasal dari kandungan metabolit sekunder yang terdapat dalam batang prasman seperti Flavonoid, saponin, tanin dan minyak atsirinya. Dengan demikian, ekstrak metanol batang prasman berpotensi sebagai sumber senyawa bioaktif yang dapat dikembangkan lebih lanjut dalam bidang farmasi, khususnya sebagai kandidat antikanker, antimikroba, dan bioinsektisida alami.

D Dowry (mahar) is an obligation of a groom to his bride in Islamic marriage, symbolizing respect and responsibility. In the Buton community, mahar also develops as a customary tradition known as boka, which carries both symbolic and socio-cultural meanings. This study aims to analyze the concept of mahar according to the Shafi’i school of law and its implementation in Taduasa Village, South Buton Regency. This research uses a qualitative method with data collection techniques including interviews, documentation, and literature review. The findings show that mahar is viewed as a symbol of respect for women and is determined based on lineage and social status. According to the Shafi’i school, such practices are permissible as long as they are based on mutual agreement and do not burden the groom. However, excessively high dowry amounts in some cases may hinder marriage. This study concludes that the mahar tradition in Taduasa Village remains consistent with Shafi’i principles but should be adjusted to the Islamic values of ease and public welfare.

High consumption of sugar-sweetened beverages (SSBs) has become an increasing public health concern, particularly among adolescents. Excessive SSB intake is a major risk factor for various non-communicable diseases, including type 2 diabetes mellitus, cardiovascular diseases, obesity, dental caries, and certain types of cancer. This study aimed to analyze the factors associated with the level of sugar-sweetened beverage (SSB) consumption among adolescents. This study employed a descriptive literature review approach. Data were obtained from national and international journals relevant to the topic of SSB consumption among adolescents. The selected articles were analyzed to identify factors associated with SSB consumption. The findings indicated that SSB consumption among adolescents is influenced by several factors, including individual factors (gender and knowledge), socioeconomic factors (peer influence and pocket money allowance), environmental factors (mass media exposure and beverage availability), and psychological factors (stress level and preference for sweet tastes). This study highlights that SSB consumption is a multifactorial behavior influenced by various interacting determinants. Therefore, comprehensive interventions targeting both individual and environmental factors are needed to reduce SSB consumption among adolescents.

Indonesia is currently experiencing an emergency situation regarding sexual violence, which compromises national social resilience. The enactment of the Sexual Violence Crimes Law (UU TPKS) creates new legal mandates for healthcare professionals. Midwives, serving as frontline providers in primary care and remote areas, act as the first professional contact for survivors, yet they lack adequate legal certainty regarding medico-legal duties and preparedness within the midwifery educational framework. Objectives: This study aims to analyze the regulatory synchronization concerning the limited medico-legal authority of midwives in implementing the UU TPKS and to formulate reconstruction strategies for professional standards and the national midwifery curriculum. Methods: This normative juridical (doctrinal) research utilizes statute, conceptual, analytical, and comparative approaches. Data analysis was conducted qualitatively-normatively through systematic and teleological interpretations, evaluated using coherence and prescriptive frameworks. Results: The study reveals a significant disharmony of norms between the UU TPKS and Minister of Health Regulation (Permenkes) No. 2 of 2025, which imposes bureaucratic barriers on safe abortion access for rape victims. Additionally, the Midwife Professional Standards (Kepmenkes No. 320/2020) fail to integrate basic clinical forensic authorities, compounded by a national techno-centric curriculum that overlooks Trauma-Informed Care (TIC). Conclusions: Legal certainty for midwives and comprehensive justice for survivors can only be accomplished by reconstructing inclusive competency standards, eliminating administrative boundaries through the "Medical First" principle, and integrating primary health law and trauma-sensitive care modules into the national midwifery curriculum.

This study aims to analyze the effect of public satisfaction on political participation in the 2024 single-candidate regional election (Pilkada) in Batanghari Regency. Political participation in elections is an important indicator of democratic quality, especially in a single-candidate contest where electoral competition is limited. The research employed a quantitative explanatory approach with a sample of 151 respondents selected through simple random sampling. Data were collected using structured questionnaires and analyzed using simple linear regression with IBM SPSS Statistics to determine the relationship between public satisfaction and political participation. The results indicate that public satisfaction has a positive and significant effect on political participation, with a coefficient of determination (R²) of 0.510. This means that 51% of the variation in political participation can be explained by public satisfaction, while the remaining percentage is influenced by other factors not included in this study. However, voter turnout in the 2024 election declined compared to the previous regional election. These findings suggest that public satisfaction is not the sole factor influencing political participation, as the level of political competition in a single-candidate election also plays an important and contextual role in shaping voter behavior and turnout.

Preeclampsia is a pregnancy complication that significantly contributes to maternal and neonatal morbidity and mortality worldwide. Globally, it affects approximately 3–8% of pregnancies and causes more than 70,000 maternal deaths each year. In Indonesia, preeclampsia accounts for around 30% of the 4,151 maternal deaths reported in 2024. In Padang City, there were 254 cases in 2023 and 129 cases in 2024, with Puskesmas Bungus having the highest prevalence (7.2% and 3.77%). This study aimed to analyze the association between body mass index (BMI), history of hypertension, and history of preeclampsia with the incidence of preeclampsia among pregnant women at Puskesmas Bungus, Padang. This study used a quantitative case-control design involving 50 cases and 50 controls. Data were analyzed using chi-square and logistic regression tests. The results showed significant associations between obesity (p=0.031; OR=2.897), history of preeclampsia (p=0.006; OR=13.821), and history of hypertension (p=0.002; OR=17.216) with the incidence of preeclampsia. Multivariate analysis identified history of hypertension as the most dominant factor associated with preeclampsia. This study concludes that obesity, history of hypertension, and history of preeclampsia are significant risk factors for preeclampsia among pregnant women. Strengthening early detection and routine antenatal care for high-risk pregnancies is necessary to reduce maternal complications associated with preeclampsia.

This study aims to analyze in-depth cognitive learning theory and its implications for improving the effectiveness of Islamic Religious Education (PAI) teaching at the elementary school level. The adopted methodological approach is qualitative through library research, with the application of content analysis and theoretical synthesis techniques. Primary data sources were obtained from academic literature including textbooks, scientific journals, and the latest empirical research relevant within the last decade. The results of the analysis indicate that cognitive learning theory positions cognitive processes as the core of learning activities, allowing students to function as active agents in constructing knowledge through understanding, analysis, memory representation, and integration with pre-existing cognitive schemas. In the context of PAI, this approach enables meaningful learning through interactive pedagogical strategies such as collaborative discussions, problem-solving, case studies, and metacognitive reflection, which are empirically adapted to the stages of students' cognitive development. The implementation of cognitive theory significantly contributes to strengthening conceptual understanding, increasing learning engagement, developing critical thinking skills, transferring knowledge, and internalizing Islamic values. Thus, cognitive learning theory makes a substantial contribution to optimizing the effectiveness of PAI teaching in elementary schools through an interactive, systematic, and understanding-oriented approach.

Indonesia merupakan produsen padi terbesar di kawasan ASEAN dengan produksi mencapai 60,3 juta ton pada tahun 2025. Meskipun demikian, tingginya produksi tersebut belum mampu meningkatkan ekspor beras secara signifikan dan Indonesia masih menghadapi tantangan dalam memenuhi kebutuhan pangan secara berkelanjutan. Kondisi ini menunjukkan bahwa peningkatan output pertanian belum tentu mencerminkan efektivitas penggunaan faktor-faktor produksi yang mendukungnya. Penelitian ini bertujuan untuk menganalisis pengaruh luas lahan sawah, jumlah petani, dan penyaluran pupuk bersubsidi terhadap produksi padi di Indonesia menggunakan pendekatan fungsi produksi Cobb-Douglas. Penelitian ini menggunakan metode kuantitatif dengan data cross section pada 10 provinsi penghasil padi terbesar di Indonesia tahun 2025. Analisis dilakukan menggunakan regresi linier berganda setelah model memenuhi pengujian asumsi klasik. Hasil penelitian menunjukkan bahwa luas lahan sawah berpengaruh positif dan signifikan terhadap produksi padi dengan elastisitas sebesar 1,038743. Sebaliknya, jumlah petani berpengaruh negatif dan tidak signifikan, sedangkan penyaluran pupuk bersubsidi berpengaruh positif namun tidak signifikan. Temuan ini mengindikasikan bahwa peningkatan produksi padi lebih dipengaruhi oleh ketersediaan dan pemanfaatan lahan yang produktif dibandingkan penambahan tenaga kerja maupun subsidi input pertanian. Penelitian ini menyimpulkan bahwa peningkatan produksi padi memerlukan kebijakan yang berfokus pada efisiensi penggunaan sumber daya, perlindungan lahan pertanian produktif, serta penerapan teknologi pertanian yang mampu meningkatkan produktivitas secara berkelanjutan.

This study aims to analyze the effect of cutting parameters on surface roughness in the turning process of AISI 1045 steel. The investigated parameters include cutting speed, feed rate, and depth of cut. A quantitative approach was employed using multiple linear regression analysis with SPSS software. The dataset consisted of 30 simulated experimental observations with varying cutting parameter conditions. Prior to regression analysis, classical assumption tests including normality, multicollinearity, and heteroscedasticity tests were conducted to ensure the validity of the model. The results indicated that all assumptions were satisfied. The findings reveal that simultaneously, all independent variables have a significant effect on surface roughness with a coefficient of determination of 82.1%. Partially, Feed rate and cutting speed significantly influence surface roughness, while depth of cut does not show a significant effect. Feed rate is identified as the most dominant variable affecting surface roughness, where an increase in Feed rate leads to higher roughness values. In contrast, increasing cutting speed tends to reduce surface roughness. This study highlights the importance of controlling cutting parameters, particularly Feed rate and cutting speed, to improve machining quality. The results provide practical implications for manufacturing industries in optimizing machining parameters to achieve better surface quality and process efficiency.

Vector-borne infectious diseases remain a public health concern, particularly in tropical regions such as Indonesia. Sanitation clinics at public health centers (Puskesmas) play a role in identifying environmental risk factors and planning interventions to support vector-borne disease control. This study aimed to evaluate the performance of sanitation clinics in environmental intervention planning. The method used was a literature review of scientific articles, journals, and related documents published between 2015-2025. Data were analyzed descriptively to identify forms of environmental interventions and their effectiveness. The results showed that sanitation clinics play an important role in environmental health counseling, sanitation inspections, health education, and environmental intervention planning. However, their implementation still faces challenges, including limited numbers of sanitarians, inadequate facilities and infrastructure, and suboptimal environmental interventions. Nevertheless, sanitation clinics continue to contribute to the prevention of environment-based diseases and vector control. Therefore, strengthening resources and improving the quality of intervention planning are necessary to enhance the effectiveness of sanitation clinic programs.
