Abstract

The aim of the study was to test the provision of feed made from kelakai with the best probiotic dose for the growth of climbing perch. It is expected that the feed formulation made from kelakai in the form of pellets will increase its growth by administering probiotics. The research method used a completely randomized design (CRD) with 4 treatments and 3 replications, rearing for 30 days in an aquarium. Treatment A: feeding pellets with 20% kelakai flour and 0% probiotics, treatment B: feeding pellets with 20% kelakai flour and 5% probiotics treatment C: feeding pellets with 20% kelakai flour and 10% probiotics, treatment D: giving pelleted feed with 20% kelakai flour and 15% probiotics. The results showed that all treatments were not significantly different, the highest relative length growth was in treatment C (20% kelakai flour; 10% probiotics), the highest relative weight growth of climbing perch was in D treatment (20% kelakai; 15% probiotics), survival 100 % in all treatments. Water quality is within a range that supports the growth and survival of climbing perch.

Abstract

Abstract. This study aims to analyze the presence Manis javanica based on environmental factors in the post-mining revegetation area of PT Arutmin Indonesia Tambang Kintap in various crop years (2016, 2018, 2020, and 2024). The methods used in this study were field surveys with primary data collection using camera traps and spatial analysis using Maxent and ArcMap software. The results of the study show variations in the suitability of M.javanica habitat between different years of planting, which are influenced by improvements in vegetation structure. Revegetation areas planted in 2016 and 2018, characterized by well-developed and dense canopy structures, serve as important habitat components for M.javanica. The results underscore the role of revegetation as an effective ecological restoration strategy for supporting M.javanica conservation in post–coal mining environmentsAbstrak. Penelitian ini bertujuan untuk menganalisis keberadaan trenggiling (Manis javanica) berdasarkan karakteristik tutupan lahan (tutupan tajuk) di areal revegetasi pascatambang PT Arutmin Indonesia Tambang Kintap pada berbagai tahun tanaman (2016, 2018, 2020, dan 2024). Metode yang digunakan dalam penelitian ini adalah survei lapangan dengan pengambilan data primer menggunakan kamera trap dan analisis spasial menggunakan software Maxent dan ArcMap. Hasil penelitian menunjukkan adanya variasi dalam kesesuaian habitat trenggiling antara tahun tanaman yang berbeda, yang dipengaruhi oleh struktur vegetasi. Tanaman revegetasi tahun tanam 2018 dan 2016 dengan tutupan tajuk rapat berkontribusi bagi penyediaan habitat trenggiling. Hasil penelitian ini memberikan kontribusi terhadap pemahaman tentang keberhasilan upaya revegetasi dalam mendukung konservasi trenggiling di lahan pasca tambang batu bara.
