Introduction: This study analyzes the disparity between Personal Protective Equipment (PPE) regulations and field practices among Live-Line Maintenance workers (PDKB) at PT PLN (Persero) UP3 Sukoharjo. The research was motivated by a fatal incident in Lubuk Pakam in 2023 and three near-miss incidents at the research location caused by negligence in the use and supervision of PPE. Research Method: This study employed a qualitative approach with a case study design. Data were collected through in-depth interviews with five informants selected purposively (technicians, preparators, team leaders, and OHS officers), field observations, and documentation review. The data were analyzed using the Miles and Huberman model. Data validity was ensured through source and method triangulation. Research Results: The findings indicate a strong organizational commitment through the provision of internationally standardized PPE, certified training, periodic testing every six months, and multi-layered supervision in accordance with Law No. 1/1970, Government Regulation No. 50/2012, and Minister of Manpower Regulation No. 8/2010. The level of worker compliance is relatively high due to awareness of the risks associated with 20 kV electrical voltage and the safety culture of “one opens, three remind,” with PPE internalized as a “second life.” However, two main disparities were identified. First, PPE storage in operational vehicles and basecamps has not yet met the ideal standard of controlled storage facilities; this condition is compensated through adaptive mechanisms such as special storage boxes, air-conditioned rooms, and psychological ownership among workers. Second, regarding PPE materials, safety sleeves that should be made of insulating rubber are still made of plastic due to previous procurement. The multi-layered supervision system, supported by peer monitoring, has proven effective in detecting three near-miss incidents before they escalated into fatal events. Conclusion: This study concludes that the effectiveness of OHS implementation is not solely determined by formal compliance based on regulations (rules-based approach), but also by organizational safety culture (safety culture-based approach) and the synergy of social capital. Recommendation: The study recommends accelerating the transition to PPE that meets current standards, improving storage facilities, and strengthening the quality of double-check procedures.

The diversity of family medicinal plants in Indonesia represents an important biological resource that supports public health and has considerable potential as a learning resource in biology; however, it has not been optimally utilized in senior high school biodiversity education. This study aims to identify medicinal plant species in Bulusari Village, analyze their distribution, and evaluate their potential as a biology learning resource based on local wisdom. The study employed an exploratory descriptive method with direct field observation and semi-structured interviews. Data collection was conducted using a total sampling technique, in which all medicinal plant species found in home gardens and surrounding village environments were recorded and identified. Data were analyzed descriptively based on botanical classification, distribution patterns, and medicinal uses. The results identified 25 medicinal plant species belonging to 19 families and 6 classes, with Asteraceae as the dominant family. The plants were distributed across cultivated home gardens and wild habitats. These findings indicate that the diversity of family medicinal plants in Bulusari Village has strong potential as a contextual biology learning resource for senior high school, supporting authentic, environment-based, and locally relevant learning.

The global shift toward sustainable and functional foods has encouraged the development of innovative alternative ingredients in bakery products. In Indonesia, the high dependence on imported wheat flour poses challenges to food security, driving the exploration of local substitutes. This systematic literature review aims to analyze the potential, characteristics, and challenges of utilizing alternative ingredients derived from tubers, legumes, and insects for sustainable bakery production in Indonesia. The study reviewed 25 national and international scientific publications from 2015–2025, focusing on nutritional composition, sensory acceptance, and technological applications. Findings indicate that tuber-based flours (such as modified cassava flour and taro) and legume-based flours (soybean, mung bean) can replace up to 30% of wheat flour without significantly affecting product quality. In contrast, insect-based flours particularly cricket flour offer high protein and micronutrient potential but still face consumer acceptance barriers. This review contributes by consolidating multidisciplinary evidence and proposing a practical framework for reducing wheat dependency through local ingredient utilization offering actionable insights for researchers, policymakers, and the bakery industry toward a more sustainable food system in Indonesia.

Commercial concentrates have different nutrient formulations, which may potentially affect body tissue growth and the development of internal organs in broiler chickens, ultimately influencing the percentage of carcass parts and internal organs. This study aimed to determine the effect of feeding two different types of commercial concentrates on the percentage of carcass parts and internal organs of broiler chickens. The experimental design used was a Completely Randomized Design with a one-way pattern consisting of three treatments and four replications. The treatments were P1: 100% commercial concentrate A; P2: 100% commercial concentrate B; and P3: 50% commercial concentrate A + 50% commercial concentrate B. The observed variables included the percentages of thigh, wing, and breast parts, as well as the percentages of heart, gizzard, and liver. The obtained data were statistically analyzed using analysis of variance (ANOVA), and when significant differences were detected, Duncan’s Multiple Range Test was applied. The results showed that the percentages of breast and thigh parts among P1, P2, and P3 did not differ significantly; however, the percentage of wing parts in P1 was significantly lower than in P2 and P3. The percentages of heart and liver in P1, P2, and P3 did not show significant differences, whereas the gizzard percentage in P1 was significantly different compared to P3. It can be concluded that feeding two different types of commercial concentrates significantly affected the percentages of wing and gizzard parts but did not significantly affect the percentages of breast, thigh, heart, and liver.
