Pertumbuhan anak usia 24–59 bulan merupakan periode penting yang dipengaruhi oleh kecukupan asupan zat gizi, salah satunya protein. Kekurangan protein dalam jangka panjang dapat menyebabkan gangguan pertumbuhan linier berupa stunting yang berdampak terhadap kualitas tumbuh kembang anak. Penelitian ini bertujuan untuk mengetahui hubungan asupan protein dengan status pertumbuhan anak usia 24–59 bulan. Penelitian ini menggunakan desain observasional analitik dengan pendekatan cross sectional yang dilakukan di wilayah kerja Puskesmas Bambu Kabupaten Mamuju. Sampel penelitian berjumlah 30 anak usia 24–59 bulan yang dipilih menggunakan teknik purposive sampling. Data asupan protein diperoleh melalui food record, sedangkan status pertumbuhan diukur menggunakan indikator antropometri berat badan menurut umur (BB/U), tinggi badan menurut umur (TB/U), dan berat badan menurut tinggi badan (BB/TB). Analisis data menggunakan uji Spearman’s Rho dan Fisher’s Exact dengan tingkat kemaknaan ?=0,05. Hasil penelitian menunjukkan bahwa 70% anak mengalami stunting berdasarkan indikator TB/U, terdiri dari kategori stunted sebesar 50% dan severely stunted sebesar 20%. Terdapat hubungan antara asupan protein dengan BB/U (p=0,05; r=0,593) dan TB/U (p=0,000; r=0,601), sedangkan tidak terdapat hubungan antara asupan protein dengan BB/TB (p=1,000; r=0,023). Kesimpulan penelitian ini adalah asupan protein berhubungan dengan status pertumbuhan anak terutama pada indikator TB/U. Pemenuhan protein yang cukup dan berkualitas, terutama protein hewani, perlu menjadi perhatian dalam upaya mendukung pertumbuhan dan mencegah gangguan pertumbuhan pada balita

Korosi pada aluminium dalam lingkungan air laut merupakan permasalahan serius yang dapat menurunkan umur pakai material. Berbagai inhibitor alami telah dikembangkan sebagai alternatif ramah lingkungan, tetapi kajian mengenai penggunaan ekstrak labu kuning sebagai inhibitor korosi aluminium dalam media air laut, terutama dengan mempertimbangkan pengaruh temperatur, masih terbatas. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi inhibitor ekstrak labu kuning dan temperatur terhadap laju korosi aluminium menggunakan metode weight loss. Variasi konsentrasi inhibitor yang digunakan adalah 0 ppm, 1000 ppm, 2000 ppm, dan 3000 ppm, dengan variasi temperatur 27°C, 35°C, dan 45°C selama waktu perendaman 24 jam. Hasil penelitian menunjukkan bahwa peningkatan konsentrasi inhibitor secara signifikan menurunkan laju korosi, dengan nilai optimum pada 3000 ppm yang menghasilkan laju korosi sebesar 0,448 mm/year dan efisiensi inhibisi sebesar 74,06%. Sebaliknya, peningkatan temperatur menyebabkan kenaikan laju korosi dan penurunan efisiensi inhibitor. Analisis parameter aktivasi menunjukkan bahwa penambahan inhibitor meningkatkan energi aktivasi (Ea) dari 17,075 kJ/mol menjadi 28,432 kJ/mol, yang mengindikasikan bahwa proses korosi menjadi lebih sulit terjadi. Secara keseluruhan, ekstrak labu kuning terbukti efektif sebagai inhibitor korosi ramah lingkungan yang bekerja melalui mekanisme adsorpsi dan pembentukan lapisan pelindung pada permukaan logam.

Tax avoidance presents a unique challenge, as it is morally acceptable and does not violate the law, yet it is detrimental to the government. There are loopholes (grey areas) in the tax code that are exploited. To further examine the influence of factors including institutional ownership, audit committees, firm age, and debt (leverage) on tax avoidance, this study aims to gather data. The analysis uses multiple regression at a 5% significance level on data obtained from 177 of 59 consumer goods sector companies listed on the IDX for the 2022–2024 period. A partial and statistically significant relationship was found between fiscal policy and factors such as firm age, institutional ownership, audit committees, and leverage. Penghindaran pajak menghadirkan tantangan khusus, karena secara moral dapat diterima serta tidak pemerintah tidak melanggar hukum, namun merugikan pemerintah. Ada celah (grey area) dalam kode pajak yang dimanfaatkan. Guna mempelajari lebih lanjut berkaitan dengan berpengaruhnya faktor termasuk kepemilikan institusional, komite audit, firm age, serta utang (leverage) atas penghindaran pajak, penelitian ini bermaksud untuk mengumpulkan fakta. Analisis menggunakan regresi berganda pada tingkat signifikansi 5% pada data yang diperoleh sebanyak 177 dari 59 perusahaan sektor barang konsumsi terdaftar di BEI periodisasi 2022-2024. Ditemukan hubungan parsial serta sinifikan secara statistik kebijakan fiskal serta faktor seperti umur perusahaan, kepemilikan institusional, komite audit, serta leverage.

Economic exploitation of children remains a serious issue within the child protection system in Indonesia, particularly in urban areas experiencing high socio-economic pressure. This study aims to analyze the forms of legal protection provided to children who become victims of economic exploitation by their parents in Manado City and to identify the factors that cause children to become involved in street-based economic activities. The research employed an empirical legal method with a socio-juridical approach. Data were collected through semi-structured interviews, documentation, library research, and case-handling records from the Office of Women’s Empowerment and Child Protection of Manado City. The data were analyzed using a qualitative descriptive method to understand the relationship between child protection legal norms and social practices within society. The findings reveal that legal protection has been implemented through preventive and repressive measures, including public outreach, legal education, psychological assistance, social rehabilitation, and inter-agency coordination. However, its implementation has not yet been optimal due to family poverty, low parental education, weak legal awareness, permissive social environments, and limited institutional capacity at the regional level. This study emphasizes that protecting children from economic exploitation requires stronger law enforcement, social protection for vulnerable families, community economic empowerment, and an integrated child protection system to ensure children’s rights to education, welfare, and development are sustainably protected.

Strawberries are horticultural commodities that are highly susceptible to postharvest deterioration due to their high respiration rate, microbial activity, and oxidative degradation, resulting in a relatively short shelf life. This study aimed to evaluate the effectiveness of edible coatings in extending strawberry shelf life through a systematic literature review (SLR) approach. Literature was collected from several scientific databases using keywords related to edible coating, shelf life, and strawberry, covering publications from 2019–2026. From an initial 109 articles, a selection process based on inclusion and exclusion criteria resulted in 35 articles specifically discussing the application of edible coatings on strawberries. The synthesis results showed that all studies reported an extension of shelf life after edible coating application, although the effectiveness was influenced by the type of material, formulation, and storage conditions. Chitosan was the most widely used coating material due to its natural antimicrobial activity and excellent film-forming ability. The incorporation of bioactive compounds such as essential oils, plant extracts, and phenolic compounds was proven to enhance antifungal and antioxidant activities. In addition, nanotechnology-based systems demonstrated better preservation performance compared to conventional systems. However, methodological standardization and industrial-scale validation are still required to support commercial implementation.

Korosi pada material stainless steel dalam lingkungan basa dan temperatur tinggi menjadi salah satu faktor yang memengaruhi umur pakai peralatan pada sistem netralisasi minyak sawit. Penelitian ini bertujuan menganalisis pengaruh temperatur dan kecepatan pengadukan terhadap laju korosi serta membandingkan ketahanan korosi baja tahan karat SS304 dan SS316 dalam larutan NaOH 1 M. Pengujian dilakukan menggunakan metode weight loss berdasarkan standar ASTM G31–72 selama 49 hari dengan variasi temperatur 70°C, 90°C, dan 110°C serta kecepatan pengadukan 100 rpm, 200 rpm, dan 300 rpm. Laju korosi dihitung berdasarkan kehilangan massa spesimen dan dianalisis menggunakan klasifikasi ketahanan korosi. Hasil penelitian menunjukkan bahwa peningkatan temperatur dan kecepatan pengadukan menyebabkan peningkatan laju korosi pada kedua material. Nilai laju korosi tertinggi diperoleh pada SS304 sebesar 0,0247 mm/tahun pada kondisi 110°C dan 300 rpm, sedangkan nilai terendah diperoleh pada SS316 sebesar 0,0124 mm/tahun pada kondisi 70°C dan 100 rpm. Secara umum, SS316 menunjukkan ketahanan korosi yang lebih baik dibandingkan SS304 karena kemampuan mempertahankan lapisan pasif yang lebih tinggi. Berdasarkan klasifikasi ketahanan korosi, sebagian besar kondisi pengujian berada pada kategori sangat baik sehingga kedua material masih layak digunakan pada sistem netralisasi minyak sawit, dengan SS316 lebih direkomendasikan untuk kondisi operasi yang lebih agresif.

Type 2 Diabetes Mellitus (T2DM) is a public health problem with a continuously increasing prevalence, and it is higher in women than in men. This study aimed to analyze the risk factors for T2DM in women aged ≥15 years in Indonesia based on data from the 2023 Indonesian Health Survey. This study was a secondary data analysis with a cross-sectional design involving 346,760 women who met the inclusion criteria. Univariate and bivariate analyses were performed using the Chi-Square test with calculation of the Prevalence Odds Ratio (POR) at a 95% confidence level. The results showed the prevalence of T2DM was 1.3%. Factors significantly associated included age ≥40 years (POR=22.4), low education level (POR=1.34), unemployed status (POR=1.18), urban residence (POR=1.91), mild physical activity (POR=1.15), obesity (POR=1.27), and overweight (POR=1.27). Protective factors included vigorous physical activity (POR=0.77) and underweight BMI (POR=0.65), while marital status was not significantly associated (p=0.135). T2DM in women is a multifactorial disease influenced by the interaction of biological, social, behavioral, and environmental factors, thus requiring risk-based promotive and preventive interventions.

The performance of Asphalt Concrete – Wearing Course (AC-WC) is greatly influenced by the characteristics of the mixture, one of which is the void value which plays a role in stability, durability, and resistance to damage. Rainwater is the most dominant environmental factor accelerating pavement damage through stripping mechanisms, bond release, and a decrease in the structural strength of the layer. Therefore, it is necessary to conduct a study on changes in void value with soaking duration, the relationship of void value to the design life of the road pavement, and an empirical model of the design life based on void value with variations in soaking in the mixture using a laboratory test approach. Based on the results of laboratory tests, it can be seen that changes in void values ​​due to variations in soaking time using rainwater indicate that the longer the mixture is soaked, the changes in VIM and VMA values ​​tend to decrease, while VFA increases. The relationship between VIM values ​​and the design life of road pavements in AC-WC layers due to soaking variations shows that the design life decreases sharply when the VIM value is <3%. Thus, long-term immersion can reduce the road life by more than 35% of its ideal design life and based on a simple empirical model equation to estimate the design life of the pavement based on the void value and immersion conditions, N0 = 12.5 years is obtained (Ideal mix design life at VIM = 4%).

Protecting the rights of children in inheritance cases is very important in Indonesian civil law. It involves things like legal ability, who takes care of the child, and making sure the child's rights are properly respected and met. This study looks into how the law protects young people in fights over inheritance, including how guardians are used, any problems where someone might benefit unfairly, and how judges should make sure the child's best interests are always considered. The study uses a normative legal approach, looking at laws and ideas by checking related civil law rules and child protection guidelines. The study shows that children cannot make their own legal decisions in court and need their parents or guardians to act on their behalf. But in real situations, there can be problems where the parents' interests might conflict with what's best for the child, which could affect the child's right to inherit property. Judges are important in checking if the guardian has the right to be in the case and making sure the claim doesn't harm the child. Legal protection in inheritance matters needs to be both official, by having proper representatives, and real, by ensuring fair treatment, clear laws, and special care for children's rights as legal beings who need extra protection.

 Sexual violence against women and children is still a serious problem in Indonesia. Girls are among the most vulnerable groups because of their young age, emotional dependence, and the imbalance of power with perpetrators who are generally older or close to the victim. Cases of violence often occur in various environments, such as within the family, early marriage, or social relationships such as dating or friendships with older men. This situation often places girls in a weak position, making it difficult for them to resist or report the violence they experience. This research aims to examine forms of sexual violence against girls in relationships with large age differences and examine legal protection based on Law Number 12 of 2022 concerning Crimes of Sexual Violence. The research uses qualitative methods through literature study by reviewing books, scientific journals, regulations, and data from the Ministry of Women's Empowerment and Child Protection. The results of the study show that unequal age relations often give rise to power inequalities that trigger domination, control and various forms of violence, such as sexual coercion, physical violence, psychological manipulation and domestic exploitation. The TPKS Law plays an important role as a basis for legal protection and fulfillment of rights for victims

The highest mortality cases during pregnancy until the postpartum period are caused by several factors such as hypertension, infection, bleeding, anemia and KEK. Data obtained from pregnant women at the Bumiayu Community Health Center in 2023 were 30 cases, in 2024 there was an increase of 183 cases and in 2025 from January to February there were 30 KEK cases (Bumiayu Community Health Center profile, 2025). The purpose of the study was to provide comprehensive midwifery care to pregnant women, childbirth, newborns, postpartum and family planning (KB) using the Varney and SOAP management approaches. The method used in this study is a qualitative descriptive method with a comprehensive case study approach. The results of the study of comprehensive midwifery care to Mrs. S found problems in pregnancy with KEK have been given management according to the mother's needs. In labor, newborns, postpartum to KB Mrs. S there were no complications. Conclusion Comprehensive midwifery care to Mrs. S with KEK has been carried out in accordance with Standard Operating Procedures with the condition of the mother and baby being good.  

Maternal mortality remains a major global health concern and an important indicator of health system performance. The World Health Organization reported in 2023 that approximately 290,000 maternal deaths occurred worldwide, highlighting persistent challenges in maternal health services. In the ASEAN region, the maternal mortality rate in 2023 was recorded at 16.85 per 1,000 live births. In Indonesia, the Maternal Mortality Rate in 2023 reached 189 per 100,000 live births according to the Ministry of Health of the Republic of Indonesia. Significant progress has been observed in Central Java Province, where the rate decreased from the United Nations Sustainable Development Goals target of 226 per 100,000 live births to 88.11 per 100,000 live births in 2023. At the district level, Brebes Regency recorded 54 cases per 100,000 live births in 2023 and reported 54 maternal deaths in 2024. Meanwhile, the Kaliwadas Community Health Center reported no maternal deaths during 2023 and 2024, indicating relatively effective maternal health services at the local level.

This study examines the juridical aspects of guardianship applications by parents to obtain permission to sell a minor’s inherited land and analyzes the judicial considerations in Decision Number 199/Pdt.P/2025/PN Blt. The research employs an empirical juridical method with a sociological legal approach. Primary data were collected through interviews and case documents at the Blitar District Court, while secondary data consist of statutes, doctrine, and related literature. Qualitative-descriptive analysis was applied to interpret the findings. The study reveals that the guardianship application process involves both administrative and judicial stages. Judges scrutinize material evidence and the probity of sale objectives, weighing important principles such as utility, legal certainty, fairness, and justice. Guardians are granted limited authority to sell a minor’s property only if it can be proven to be in the child's best interest and legal protections are assured. Recommendations include strengthening post-decision monitoring, enhancing legal outreach, improving procedural transparency, and ensuring comprehensive implementation.

This study aims to analyze the investigation process involving children as perpetrators of trafficking in persons at the Women and Children Protection Unit (PPA) of Bukittinggi Police Resort and to assess the forms of legal protection provided at each stage of the examination. This research applies an empirical juridical approach by combining literature review and field research through interviews with investigators and related parties. The findings indicate that the investigation process has been conducted in accordance with Law Number 11 of 2012 concerning the Juvenile Criminal Justice System, while upholding the principle of the best interests of the child. Legal protection is implemented through legal assistance, closed hearings, limited detention periods, and coordination with relevant institutions to support the child’s recovery and rehabilitation. However, several obstacles remain, including the limited number of investigators, restricted investigation timeframes, and difficulties in presenting witnesses. This study concludes that legal protection for children involved as perpetrators of trafficking in persons has been carried out in line with normative regulations, yet it requires strengthened institutional capacity and inter-agency coordination to ensure more effective implementation.

Male reproductive performance serves as a foundational metric for predicting the reproductive quality traits of progeny. This study aimed to investigate the interaction between semen quality in Etawa Grade (PE) and Boer bucks and non-genetic factors, specifically age and season. The research utilised secondary data on fresh semen production collected from 2018 to 2022. Quality parameters evaluated included ejaculate volume and individual sperm motility. Data were obtained from the Central Java Artificial Insemination Center and analysed using the Statistical Analysis System On Demand for Academics to determine the interactive effects of age and season on fresh semen production. The results indicated that bucks in the younger age category tended to produce higher semen volumes compared to other age groups. In conclusion, there is a general interaction between age and season on the semen quality of PE and Boer bucks. The interaction observed in fresh semen volume and motility was significantly influenced by individual age differences and seasonal factors based on rainfall levels. Further research is warranted to investigate these interactions across additional macroscopic and microscopic parameters.

A high-risk pregnancy is a pregnancy that can affect both the pregnancy, delivery, newborn, and postpartum period. There are several high-risk pregnancies, including pregnant women who are <145cm tall, have low birth weight, are too young, and give birth too closely spaced, or what is known as the 4T. Prevention is carried out by conducting comprehensive supervision, this is a way to reduce MMR and IMR. The Central Java government has developed the One Student One Client (OSOC) program, it is hoped that the implementation of this program can reduce MMR in Central Java. MMR according to WHO in 2023 reached 189/100,000 live births, MMR based on ASEAN reached 235/100,000 live births, MMR according to the Indonesian Ministry of Health reached 205/100,000 live births, MMR in Central Java in 2023 has reached 485/100,000 live births, MMR in Brebes in 2023 54/100,000 live births and at the Bantarkawung Community Health Center MMR in 2023 amounted to 2 cases of maternal death. In this study, researchers used Varney and SOAP to document midwifery care comprehensively, with direct qualitative descriptive approach methods such as observation, interviews, and documentation.
