Abstract

National energy security can be achieved by improving energy security at the village scale. Village energy independence can be achieved if at least 60% of the village's energy needs can be met by utilizing local energy potential. To determine the energy independence of a village, it is necessary to collect data on total energy usage and the potential generation of existing energy source. Medowo Village was chosen as a case study because this village actively use biogas as energy source for cooking. This study was conducted using a mixed method approach with an explanatory sequential design type. The descriptive method is used to describe the condition of energy supply in Medowo Village. The quantitative method is used to determine the condition of supply-demand and the potential for biogas generation. Primary data collection was carried out through questionnaires and direct observation at the location. Meanwhile, secondary data collection was obtained from literature studies, KUD Kertajaya, and related government agencies. It was found from the study that current biogas production only reach 40.31% of the theoretical biogas production potential. As for total energy mix, biogas contribution is 15,37%. Therefore alternatives are offered to achieve energy independence by paying attention to problems encountered during research.

Abstract

Embung Bandung Bondowoso Tourism offers water tourism which originates from the Pacal River, Bojonegoro Regency. The choice for developing Embung Bandung Bondowoso tourism is because it is to utilize the embung which has been owned since 2020. Even though Bandung Bondowoso tourism has been open since February 1st 2022 and is currently still in the development process. The development of tourist villages is also a form of accelerating integrated village development to encourage social, cultural and economic transformation of villages. This research uses quantitative research methods. In this research, this was done by filling out a Multidimensional Scaling questionnaire and then analyzing the quantitative data obtained to answer the problem formulation regarding the sustainability status of the research location. The resulting index value shows that the 5 dimensions (ecological, social, economic, institutional and technological) of Embung Bandung Bondowoso Tourism already have very good sustainability status. The sensitive attributes that most influence sustainability and need to be considered are green open spaces, condition and availability of clean water, landslides, erosion and damage to water resources, conflicts of interest between residents, level of education, development of local products, community service providers and ease of reaching the location.

Abstract

Farming the shrimp, fish and another commodity could produce large quantities of waste. Aquaculture waste can be formed as feces, residual feed and dead organism which are accumulated in a cultivation area. Generally, the waste is discharged directly into the water without filtration. Thus, one of the problems that are often faced by farmer is the low quality of pure water due to the high content of nutrients. Moreover, suspended solid pollutant will be formed that lead to eutrophication, oxygen depletion, and precipitation. The aim of this research is to analyze the solid waste pond tiger shrimp as fertilizer for the growth of Caulerpa lentiilifera. Here, the Random Design complete (RAL) and three times in Deuteronomy are used in the experiment. The parameters of one control and three treatment doses are used 0, 2, 4, and 6 g.L-1 respectively. The results showed that solid waste shrimp ponds can be used as fertilizer to meet the needs of Caulerpa lentillifera for growth and the results show the highest value is found in the dose of 6 g.L-1 with NO3- (4.58 ppm), NH4+ (3.34 ppm), PO43-  (2.03 ppm) and the value of the rate of growth and the PH are obtained (3.64 g.day-1) and (6,4-8), respectively. Keywords: Caulerpa lentillifera, growth rate, Nitrification, solid waste, Tiger Shrimp.

Abstract

Acne vulgaris is a common inflammatory skin disorder largely associated with the proliferation of Propionibacterium acnes. Although antibiotics are widely used for acne treatment, the increasing incidence of antibiotic resistance necessitates the exploration of effective natural alternatives. Mangrove plants are known to contain diverse bioactive compounds with antimicrobial potential. This study aimed to evaluate the antibacterial activity of Natural Deep Eutectic Solvent (NADES) extracts derived from young and old leaves of Avicennia marina against P. acnes. Extraction was conducted using citric acid–glucose-based NADES with different molar ratios: P1 (1:1), P2 (2:1), P3 (3:1), and P4 (4:1), to assess the effect of solvent composition on antibacterial performance. Antibacterial activity was determined using inhibition zone assays, while molecular docking analysis was performed to investigate interactions between extracted metabolites and P. acnes target proteins. The results showed that both young and old leaf extracts exhibited significant antibacterial activity, strongly influenced by the NADES formulation. Young leaf extracts produced the largest inhibition zone with the P4 formulation (24.51±0.75 mm) and the smallest with P1 (21.63±0.67 mm). Similarly, old leaf extracts showed maximum inhibition in P4 (37.38±4.34 mm) and minimum inhibition in P1 (22.62±1.40 mm). Increasing the proportion of citric acid enhanced the extraction of bioactive compounds responsible for antibacterial activity. Molecular docking confirmed strong binding affinities between key metabolites and P. acnes target proteins, supporting the experimental findings. Thus, NADES extracts of A. marina leaves, particularly those prepared using a 4:1 citric acid–glucose ratio, demonstrate strong potential as natural antibacterial agents for acne prevention and treatment.

Abstract

Stunting is a chronic nutritional deficiency that impedes growth and affects the development of body and brain cells. Addressing stunting requires multisectoral collaboration to reduce and prevent stunting among children under 5 years old, the critical "Golden Age" period. Malang City's stunting rate was 18% in 2022, 16% in 2023, with a 2024 target of 14%. Achieving zero stunting involves a multidisciplinary approach, considering environmental, social, and economic factors within a sustainable development framework. This study examines the roles of the community, stakeholders, and government in stunting management. A quantitative approach using explanatory research was conducted on pre-school children in Karangbesuki Village, with a sample of 112 families at risk of stunting from a population of 584. Data was collected through offline questionnaires, and analysis was performed using SEM-PLS software. The study found that environmental sanitation had no significant direct effect on stunting management but positively influenced women's intervention and food security. Both women's intervention and food security significantly impacted stunting management. Furthermore, women's intervention and food security played a perfect mediating role in the relationship between environmental sanitation and stunting management. Future research should consider expanding the sample size and exploring additional independent variables beyond the current framework.

Abstract

Shrimp aquaculture generates wastewater that may affect coastal ecosystem quality if not properly managed. This study aimed to analyze the relationship between shrimp pond effluent quality and macrozoobenthos diversity as an indicator of habitat suitability in the coastal waters of Situbondo, Indonesia. Wastewater samples were collected from pond outlet wastewater treatment plants (WWTP) in triplicate and analyzed for physicochemical parameters, including phosphate (PO₄), ammonia (NH₃), total suspended solids (TSS), biochemical oxygen demand (BOD), and pH. Macrozoobenthos samples were collected at three distances from the discharge point and analyzed using the Shannon–Wiener diversity index (H'). Data were further analyzed using multiple linear regression and Canonical Correspondence Analysis (CCA) to evaluate the relationship between environmental variables and macrozoobenthos diversity. The results showed that PO₄ concentrations at all stations exceeded the environmental quality standard (0.5 mg/L), while NH₃ concentrations exceeded the standard (5 mg/L) at four stations. TSS levels also exceeded the permitted threshold (100 mg/L) at several stations, whereas BOD and pH remained within acceptable limits. The macrozoobenthos diversity index indicated moderate diversity at stations 1 and 2 (H' ≈ 2), suggesting moderate environmental stress, while stations 3, 4, and 5 showed low diversity (H' < 1), indicating polluted conditions. Regression analysis indicated that nutrient and suspended solid parameters negatively influenced macrozoobenthos diversity, with PO₄ and NH₃ showing the strongest effects. The findings demonstrate that shrimp pond effluent can alter benthic community structure and confirm that macrozoobenthos are effective bioindicators for assessing ecological impacts in coastal ecosystems.

Abstract

Safe sanitation is crucial for protecting public health and the environment, particularly in densely populated urban areas where inadequate facilities heighten contamination risks. Cemorokandang Urban Village represents such a vulnerable area, requiring a comprehensive assessment to inform local sanitation planning. This study evaluates the condition of safe sanitation and identifies spatial and social factors influencing its achievement using a mixed-method approach that integrates surveys, field observations, water quality testing, and GIS-based spatial analysis. Primary data covered household sanitation facilities, open defecation practices, and water quality, while secondary data were obtained from local institutions. Findings indicate that although all households have toilets with domestic wastewater systems, only 3,25% (211 of 6.497 buildings) met safely managed sanitation criteria despite 96.75% having adequate facilities. Spatial analysis reveals significant variation in sanitation risk across neighborhoods, strongly linked to differences in education, income, and community behavior. Communities with stronger socio-economic capacity demonstrate better understanding and adoption of safe sanitation practices, supported by training and balanced gender participation. Integrating spatial and social data provides a detailed picture of local challenges and supports the design of community-based, location-specific, and gender-responsive interventions. The study recommends targeted actions in high-risk areas, strengthened behavioral training, and inclusive financing mechanisms to accelerate progress toward Sustainable Development Goal 6.2.1.
