Abstract

Diversity bird is indicator important in evaluate habitat quality and stability ecosystem forests, especially in the area conservation. Research this aim for analyze diversity type birds on two different habitat types, namely forest and plantation habitat types, in the Patok National Park Management Resort (RPTN) area Picis, Bromo Tengger National Park Semeru (TNBTS). Research done for identify influence difference condition structure vegetation and intensity activity man to composition community bird. Data collection using point count method on points specified observations in a way purposive sampling, with analysis covering index Shannon-Wiener diversity (H'), index evenness (E), and index dominance (D). Research results show that in the forest habitat type own diversity type and quantity more individuals tall compared to plantation habitat type, with a total of 40 species and 163 individuals, while in the plantation habitat type only 15 species and 73 individuals were found. The differences the influenced by the availability of higher vegetation strata complex in forest habitat, whereas condition plantation more homogeneous and potential increase dominance species certain. Problems identified ecological that is decline riches types in fragmented landscapes, particularly in edge zones and wetlands cultivation community. Research This recommend the need improvement effort habitat management in the area RPTN Patok support Picis through conservation mosaic vegetation, reduction pressure anthropogenic, as well as strengthening collaboration with society. Overall, research This confirm importance quality of habitat in maintain diversity of avifauna in the area conservation.

Abstract

Limbah vinasse merupakan hasil samping industri bioetanol yang memiliki kandungan bahan organik tinggi dan berpotensi mencemari lingkungan apabila tidak dikelola dengan baik. Penelitian ini bertujuan mengevaluasi pemanfaatan limbah vinasse sebagai bahan baku pupuk organik cair (POC) melalui proses fermentasi anaerob dengan penambahan kotoran sapi, sekam padi, dan Effective Microorganisms 4 (EM4). Penelitian dilakukan secara eksperimental dengan variasi waktu fermentasi selama 7, 14, dan 21 hari. Parameter yang dianalisis meliputi Chemical Oxygen Demand (COD), C-organik, N-total, P₂O₅, K₂O, N-organik, serta unsur mikro sesuai Keputusan Menteri Pertanian Nomor 261/KPTS/SR.310/M/4/2019. Hasil penelitian menunjukkan bahwa seluruh perlakuan mengalami penurunan COD selama fermentasi. Perlakuan terbaik diperoleh pada fermentasi 21 hari dengan kombinasi vinasse, kotoran sapi, sekam padi, dan EM4 yang menghasilkan nilai COD sebesar 286,246 ppm. Produk POC yang dihasilkan dari formula LV+KS+EM4 dan LV+KS+SP+EM4 memenuhi persyaratan mutu pupuk organik cair berdasarkan standar yang berlaku. Hasil penelitian menunjukkan bahwa limbah vinasse berpotensi dimanfaatkan sebagai bahan baku pupuk organik cair yang bernilai guna sekaligus mendukung pengelolaan limbah industri yang lebih berkelanjutan.

Abstract

An ethnic group is a community of people connected by similarities in race, religion, national origin, or a combination of these elements, and bound by a shared cultural value system. According to the Encyclopedia of the Indonesian Language, an ethnic group refers to a social group within a society or cultural context that holds specific meanings or positions due to lineage, customs, religion, language, and other factors. This study aims to identify the processes of interreligious harmony occurring among the Tenggerese indigenous community through their existing intellectual and social capital, and to examine the structure of social capital within the indigenous community in fostering social harmony. The research employs an analytical method with data collected through literature review and fieldwork. The findings demonstrate that the Tenggerese indigenous community preserves its local wisdom through values upheld in the process of harmonization, and that such wisdom is sustained within society largely through the influence of prevailing myths.
