Abstract

Mount Slamet is an active volcano in Java Island, Indonesia. Slamet volcanic rocks comprise various igneous and pyroclastic rocks, including basaltic lava, andesitic lava, pyroclastic rocks, and intrusions. Geochemical analysis of rocks in the studied area (301300 mE - 303300 mE and 9189400 mN - 9191400 mN) showed the presence of high calcium and iron elements. This geological study aims to determine the potential of material resources contained to be used for agricultural needs. The potential nutrients to be found such as P, K, Mg, Ca, Fe, Ti, Na, Mn, and Si with a DHL conductivity value of 0.0473 - 0.1318 mmhos /cm are classified as non-salinity, which is safe for soil improvement. Then the neutralization value relative to calcite is between 15.45 - 27.27 %, and the abrasion pH value is between 8.05 - 8.91. The agrogeological analysis shows that the Slamet volcanic rock in Baturraden area has good prospects as an ameliorant for highly weathered (acid) soils.

Abstract

Environmental message media programs aim to foster students' attitudes of environmental care. Waste management within the campus environment remains a major challenge in realizing a sustainable Green Campus concept. This study aims to analyze the role of environmental message media in supporting the Green and Clean movement as an effort to cultivate environmental awareness among Biology students at Universitas Negeri Surabaya, particularly regarding campus cleanliness and waste management. The study employed a quantitative approach using a one-group pretest–posttest design. The intervention was implemented through the installation of educational banners and waste-sorting labels in strategic areas of the Biology Building, FMIPA UNESA, containing positive persuasive messages about cleanliness and environmental conservation, along with clean-up and waste recycling activities. The results indicate a statistically significant increase in students' levels of awareness and participation in environmental management after the intervention, although the observed improvement was not statistically significant. Environmental message media with attractive and contextual designs were shown to enhance students' attention, understanding, and emotional engagement with campus cleanliness issues. This study provides an initial overview of the effectiveness of visual communication in building a culture of environmental care in higher education settings and supports the implementation of SDGs 12.5 through waste reduction, prevention, and recycling activities.

Abstract

Catfish farming still faces the problem of high feed costs, so economical and sustainable alternative feeds are needed. Lemna minor has the potential to be used as an alternative feed due to its high nutritional content, but its growth productivity is relatively low without added nutrients. The use of eco-enzymes made from household organic waste as organic liquid fertilizer is a solution to increase the productivity of Lemna minor while supporting sustainable waste management. This study aims to describe the content of eco-enzymes from organic waste, describe the effect and determine the most effective concentration of eco-enzymes in increasing the cover area (LCA) and biomass of Lemna minor, as well as assess its impact as an alternative feed supporting SDG 2. The research was conducted from September to November 2025 at Kampoeng Pintar Oase and consisted of two stages, namely observation of the eco-enzyme production process and experimentation with its implementation in Lemna minor cultivation. The parameters observed included the macro nutrient content of eco-enzymes, cover area (LCA), Lemna minor biomass, and cultivation media quality. Nutrient content analysis was conducted at the Surabaya Laboratory of the Agency for Standardization and Industrial Services (BSPJI) based on the 2011 standard for liquid organic fertilizer quality. The data were analyzed descriptively quantitatively, followed by one-way analysis of variance and Duncan's test at a 5% level. The results showed that eco-enzyme met the standards for liquid organic fertilizer and had a significant effect on the growth of Lemna minor. A concentration of 20 ml of eco-enzyme produced the highest LCA and biomass values, while a concentration of 60 ml showed the lowest growth. These findings indicate that eco-enzyme at the optimal concentration effectively increases Lemna minor production and supports sustainable food security in line with SDG 2.

Abstract

High consumption of rice in Indonesia produces rice washing water waste, which provides an incentive to utilize rice washing water waste into Liquid Organic Fertilizer (LOF). Research at Kampoeng Pintar Oase aims to describe the quality of Rice Washing Water Waste (RWWW) LOF, the effective concentration of RWWW LOF application on plant height, number of leaves, weight and morphology of curly lettuce, and the role of RWWW LOF in curly lettuce cultivation to support SDG 2. The research was analyzed descriptively quantitatively. The research went through two stages, production of LOF through observation with parameters of N, P, K, Fe, organic C, and C/N ratio, and the implementation of LOF on curly lettuce plants through experimentation conduted with four treatments (P0: control, P1: 25%, P2: 50%, P3: 75%) and three repetition. Nutrient testing was carried at the BSPJI Laboratory. Quality test results showed that the nutrient content of LOF was low compared to the Ministry of Agriculture's standard quality No. 261 of 2019. Despite the low nutrient content, LOF implementation affected curly lettuce growth, as observed through plant height, number of leaves, wet weight, and the morphology. The most effective concentration was P3 (75%), which yielded the best results with an average height of 17.6 cm, 9 leaves, and a fresh weight of 33 gram. Beyond biological growth, utilizing RWWW LOF provides substantial economic benefits by reducing cultivation costs. This circular economy model promotes community level zero waste practices and directly contributes to sustainable agricultural targets under SDG 2.

Abstract

Banana utilization is mainly focused on the fruit, while other parts such as banana heart are often considered waste. Banana heart waste is abundant but has not been optimally utilized, even though it contains fiber, crude protein, flavonoids, tannins, vitamins, and minerals including calcium, phosphorus, and iron. Probiotics are live microorganisms that provide health benefits when administered in sufficient amounts and play important role in improving digestive health and livestock productivity, including Balitbangtan’s Superior Village Chicken. This study aimed to process banana heart waste into probiotics through fermentation using Lactobacillus sp., which functions to break down complex compounds into simpler forms and enrich metabolites. Fermentation was carried out for seven days with the addition of Lactobacillus sp. Parameters observed included microbial viability, pH, and colony morphology. Data were analyzed descriptively using quantitative methods by calculating average values and comparing them with probiotic standards. The results showed that banana heart-based probiotics had microbial viability 10⁶–10⁷ CFU/mL and pH 4.89. Colony morphology exhibited typical characteristics of Lactobacillus sp., including opaque, smooth and shiny surface, circular, flat elevation, entire margin, and diameter 2 mm. These results indicate that banana heart probiotics meet probiotic quality standards and have potential application for KUB chickens.
