Abstract

Chicken is one of the most sought-after livestock commodities in Indonesia. However, it hasn’t been optimally implemented due to the high price of feed and chicken stocks that still depend on imports. One solution is to find an alternative feed (coffee husk) and cultivate hybrid chickens, for example Golden Kamper from Gama Ayam Research Team. Coffee is a popular trading commodity in Indonesia. However, the use of coffee husk is still not optimal. Coffee husk contains crude protein in the range of 11% and will increase if fermented. Therefore, coffee husk has the potential to be an alternative feed for chickens. The purpose of this study was to determine the effect of fermented coffee husk feed on body weight and cGH (Chicken Growth Hormone) gene expression in F6 Golden Kamper chickens and to determine the effectiveness and potential of coffee husk as an alternative feed for chickens. The study was conducted by making coffee skin fermentation with EM4, making feed composition, raising DOC at the starter point (three weeks old), collecting chicken weight data, and analyzing of gene expression. The results showed that the fermentation process was able to reduce the crude fiber content in coffee husk by up to 12%. Feeding with 10% coffee husk gave better results than the 20%​. Meanwhile, the results of body weight and carcass in chickens were not significantly different in the two treatments. Gene expression analysis showed that feeding with 10% coffee husk treatment resulted in a gene expression level twice as high as 20%. The correlation test showed no correlation between chicken weight and cGH gene expression levels.

Abstract

Sayangheulang Beach, located in Garut Regency, features a diverse intertidal zone that plays a crucial role in maintaining coastal ecosystem balance. The area serves as an important habitat for marine hydrophytes and various macrozoobenthos, whose interactions are essential for understanding ecological dynamics. This study examines the biodiversity of marine hydrophytes and their relationship with macrozoobenthos at Sayangheulang Beach in Pameungpeuk District. Data was collected in three days using line transect and quadrat methods at two stations (east and west). Environmental parameters, including temperature, salinity, depth, and brightness, were measured. Diversity analysis utilized the Shannon-Wiener index, Simpson's dominance index, and evenness index, with Spearman's correlation applied to explore relationships between variables. Results indicated that both hydrophytes and macrozoobenthos exhibited moderate to high levels of biodiversity, characterized by low dominance and high evenness, suggesting a stable community. The data showed that the hydrophytes community was dominated by the Phaeophyceae class, and the macrozoobenthos was dominated by Gastropods. Interestingly, the correlation test revealed a low association between brown macroalgae and macrozoobenthos at the eastern station. This implies that hydrophytes and macrozoobenthos can coexist independently, forming intricate ecological interactions in the intertidal zone of Sayangheulang Beach.

Abstract

Cicalengka Biodiversity Park (Kehati) is a conservation area with great potential for preserving local flora and fauna, especially in Kampung Ciseupang. The community’s knowledge of utilizing traditional medicinal plants is an important local wisdom that supports conservation efforts. This study aims to identify the types, uses, processing methods, and plant parts utilized by the Kampung Ciseupang community for traditional medicine, as well as to identify the distribution of medicinal plant families in Kehati Cicalengka. The method used was qualitative descriptive through semi-structured interviews, with informants selected by purposive sampling. Data collection techniques included direct observation, exploration, and documentation. Based on exploration results, 126 species of medicinal plants from 48 families were found in Kehati Cicalengka, dominated by Fabaceae, Euphorbiaceae, and Malvaceae families. Interviews showed that 67 plant species utilized by the community as traditional medicine come from 33 different families, with Lamiaceae, Asteraceae, and Myrtaceae as the most abundant families. The most frequently used plant part was the leaf, commonly processed by boiling as a simple extraction method. The use of medicinal plants is mostly aimed at treating skin diseases. This study reveals that local knowledge passed down through generations plays an important role in conserving medicinal plants and maintaining sustainable local wisdom.

Abstract

Amyda cartilaginea is a species of softshell turtle commonly found in rivers and swamps. However, data on its population and distribution in the Special Region of Yogyakarta (DIY), especially in Sidorejo Village, Kulon Progo, remain limited. This research aimed to understand the population and distribution of Amyda cartilaginea in the two main rivers of Sidorejo Village, which are Kedung Ingas River and Sidorejo River. Research was done from December 2024 to June 2025 using combination of VES (Visual Encounter Survey) with Time-constrained Search method. Sampling was done twice day and night. Analysis using QGIS, NNI and density formula. The population of Amyda cartilaginea was higher in the Kedung Ingas River compare to Sidorejo River. The distribution of Amyda cartilaginea was evenly distributed on the upstream to midstream part of both rivers.

Abstract

The city of Yogyakarta is an endemic area for Dengue Fever (DF) as one of the vector-borne diseases. Various vector control strategies have been carried out for this disease, including the use of synthetic insecticides. However, long-term and continuous use of insecticides, as well as uncontrolled dosing, can lead to resistance in mosquito populations. This study aims to examine the characteristics of breeding sites and the resistance status of Ae. aegypti mosquitoes from Sorosutan Sub-district against permethrin using the CDC Bottle Bioassay. Observations of breeding site characteristics and egg collection were conducted in 100 randomly selected households. Mosquito rearing and resistance testing were carried out at the Entomology and Vector Control Laboratory, Public Health Laboratory Center, Yogyakarta. The breeding site characteristics found consisted of open water bodies, with larvae most frequently found in plant vases and cement bathtubs, rainwater storage buckets, and used items (plastic packaging, jars). In Sorosutan Subdistrict, the Entomological Index shows a CI value of 23.33%, HI 37%, and BI 42%, indicating that this area has a high vector density. Resistance test results show that Ae. aegypti mosquitoes have developed resistance to permethrin at 1x dose (0.75μg/bottle) and 5x dose (3.75μg/bottle), a condition that potentially results in moderate to high disease transmission.
