Abstract

Aceh Patchouli is a C3 plant that does not require high water input and full light intensity to grow optimally, making it suitable for intercropping under main crops. This study aimed to determine the water requirements and adaptability of two Aceh patchouli varieties (Tapak Tuan and Sidikalang) under low light conditions using artificial shade. The experiment employed a nested box design with two factors: shade levels and plant varieties. Observed variables include macroclimate, microclimate, and agronomic parameters such as plant height, number of leaves, leaf area, dry leaf weight, and total biomass. Water requirement and water use efficiency (WUE) were also analyzed. Results showed that shading reduced plant water needs: 33.29% L/plant without shade, 32.80 L/plant under 30% shade (1.5% reduction), and 30.30 L/plant under 60% shade (9% reduction). The Tapak Tuan variety had a higher water requirement (33.30 L/plant) compared to Sidikalang (30.96 L/plant). Importantly, increasing shade levels led to improved water use efficiency, although the variety did not significantly influence WUE.  The findings indicate that the use of shade in patchouli cultivation not only conserves water but also enhances efficiency, supporting its potential for sustainable intercropping systems in shaded or water-limited environments.

Abstract

Land use change significantly affects water quality, particularly in watersheds. This study assessed the water quality of the Upper Welang Watershed, East Java, using the STORET method in relation to land use types. Water quality assessment involves comparing measured data with the National Water Quality Standard (Government Regulation No. 22 of 2021). Water samples were collected during the dry season (March to July 2023) from forest, plantation, rice field, dry field, settlement, and industrial areas. Parameters analyzed included pH, DO, BOD, COD, NO3, TDS, Pb, Cd, and coliforms. Results showed that water quality declined in areas with high anthropogenic activity, particularly in industrial and settlement zones, with COD and NO3 levels exceeding national standards. Rivers with stable substrates and sufficient habitats exhibit better water quality. The findings highlight the importance of land use management in watershed conservation

Abstract

The growing population and improving living standards are resulting in higher demand for energy and materials. Renewable energy addresses this challenge while reducing greenhouse gas emissions. Organic waste has significant potential to be converted into pellet-based renewable energy, but sustainable production is essential to minimize environmental impact. This study aims to evaluate the environmental impact using a life cycle assessment with 5 categories, namely Global Warming Potential (GWP), Stratospheric Ozone Depletion (SOD), Terrestrial Acidification (TAC), Freshwater Eutrophication (FEU), and Human Carcinogenic Toxicity (HCT) for each pellet. The results of twig and leaf pellets were, respectively, GWP of 3.05 kg CO2-eq and 0.54 kg CO2-eq; SOD of 1.6×10–6 kg CFC11 eq and 1.35×10–7 kg CFC11-eq; TAC of 0.0131 kg SO2-eq and 0.0018 kg SO2-eq; FEU of 0.0059 kg P-eq and 0.0006; HCT 0.538 kg 1.4-DCB-eq and 0.0130 kg 1.4-DCB-eq. Based on the result, the production of twig pellets has a higher environmental impact than that of leaf pellets. However, when compared to conventional fuels, the impact caused by twig pellets is still within acceptable limits and is comparatively lower.

Abstract

Application of fertilizers and mulches can potentially improve crop productivity. However, the effectiveness and sustainability of these inputs depend on how they are managed. The objective of this study is to evaluate the effects of organic and chemical fertilizers, and plastic and bamboo leaf mulches, on the physiological growth and productivity of curly chili (Capsicum annuum L.). Experiment was performed according to a randomized block design with two factors. First factor was fertilizer (P) types consisting of three levels, namely: P0 (no fertilizer), P1 (ecoenzyme organic fertilizer), and P2 (NPK fertilizer). The second factor is the type of mulch (M) consisted of three levels, including M0 (without mulch), M1 (bamboo leaf mulch), and M2 (plastic mulch). Independent parameters included plant height, leaf number, and fruit weight. Results showed that fertilizer type had no significant effect, while plastic mulch significantly improved all parameters. No interaction was observed. These results suggest that plastic mulch effectively enhances chili growth and yield, particularly in the vegetative stage, but its long-term effects warrant further research.   Keywords: Bamboo leaf mulch, Chemical fertilizer, Curly chili, Organic fertilizer, Plastic mulch.

Abstract

Seagrass beds, particularly those found in Pulau Pahawang Village, serve as vital marine ecosystems that support diverse marine life. This study aims to investigate the composition and diversity of macrozoobenthos within these seagrass ecosystems. Seagrass and macrozoobenthic data were gathered through a 30 m line transect and 1m×1m. The samples were identified to the species or genus level, and the data were analyzed for composition and diversity using the Shannon-Wiener (H’), Dominance (C), and Evenness (E) indices. To assess the relationship between seagrass cover and macrozoobenthic density, a Pearson correlation test was performed. The seagrass species found is Enhalus acoroides. The macrozoobenthic community found in the seagrass ecosystem consists of 2 classes: 22 Gastropoda and 16 Bivalvia. The diversity index of macrozoobenthos (1.47-2.81) show moderate diversity, with high similarity (0.638–0.917), amd low dominance (0.059–0.265) indicates a balance community. The environmental conditions, including water temperature (30.8°C–31.8°C), salinity (30–31), and dissolved oxygen (5.8–6.8 mg/L), strongly support the growth of seagrasses and macrozoobenthos. This study emphasizes the importance of monitoring water quality and species diversity to ensure the sustainability of the seagrass ecosystem and other in Pulau Pahawang Village.   Keywords: Biodiversity, Enhalus acoroides,  Macrozoobenthos, Seagrass beds, Water quality.

Abstract

This study explores the diversity of Non-Timber Forest Products (NTFPs) in the Forest Zone with Special Purpose (KHDTK) of Getas-Ngandong, East Java, Indonesia, with the aim of optimizing resource allocation, livelihood diversification, and biodiversity conservation in its planning and management. By conducting a six-month (May–October 2018) biophysical survey through direct observation, coupled with structured social surveys and interviews with key informants in adjacent community-managed forest area. We identified a wide range of NTFPs that are critical for sustainable forest management. Understanding the diversity and distribution of NTFPs is necessary to inform strategic interventions that enhance forest sustainability while supporting the economic resilience of surrounding communities. The findings reveal a rich variety of NTFPs within the region, with agricultural and food crops such as corn, sugarcane, rice, and cassava prevalent inside forest areas, while fruits like mangoes and bananas dominate the surrounding non-forest areas. These insights can serve as valuable inputs, such as integrating fruit tree cultivation into agroforestry zones to enhance income stability, for developing a KHDTK management plan that diversifies income sources, supports local livelihoods, and promotes sustainable forest management practices by balancing economic, ecological, and social benefits.   Keywords: Non-Timber Forest Products (NTFPs); Sustainable Forest Management; KHDTK Getas-Ngandong.

Abstract

Processing palm fruit produces crude palm oil. Crude palm oil levels continue to increase during the fruit ripening process. The parameters used in determining the maturity criteria for palm oil harvest are color change and fruit breaking off from the bunch. Harvest quality is determined by the mature fraction. One of the problems that occurs in palm oil factories is the selection of palm fruit bunches (FFB), which are divided into three classes, namely unripe, ripe and over ripe. Selection of FFB is done manually, namely visually. The quality of palm oil is greatly influenced by the level of ripeness of the fruit at the time of harvest and post-harvest handling until the mill. This research aims to evaluate the use of variations in palm fruit maturity used in PKS which are related to yield and quality as well as oxidative stability and color. The research results showed that the variation in palm fruit maturity used resulted in the highest yield, namely 17% in P2. The quality of crude palm oil obtained from variations in fruit maturity shows different results, where the highest free fatty acid content of 2.57% is located in P2, namely a mixture of ripe and overripe fruit, while the highest water content is found in P2, namely 0.65 %. P3 has the highest impurity content of 0.68%. The oxidative stability and color obtained from using variations in fruit maturity that were heated for 24 hours decreased in value to red and yellow
