Abstract

Sungai memiliki peranan penting dalam kehidupan manusia dan mahluk hidup lainnya. Makrozoobentos menempati habitat di dasar sungai. Keanekaragaman makrozoobentos berperan penting pada ekosistem sungai. Penelitian ini bertujuan untuk menganalisis keanekaragaman makrozoobentos Sungai Lowatag berdasarkan Indeks Keanekaragaman Shannon-Wiener (H’). Penelitian ini menggunakan metode purposive random sampling di sepanjang Sungai Lowatag. Stasiun penelitian sejumlah tiga stasiun yaitu hulu, tengah dan hilir dengan ulangan di tiap stasiun berjumlah tiga kali ulangan. Makrozoobentos yang ditemukan di Sungai Lowatag memiliki kelimpahan total sebanyak 1.115 individu (35 taksa). Kelimpahan makrozoobentos di Stasiun I, II, dan III berturut-turut yaitu 26,37%, 44,39 % dan 29,24%. Nilai Indeks Keanekaragaman Shannon (H’) dari Stasiun I, II dan III berturut-turut yaitu 2,97; 2,69; dan 2,61. Nilai H’ untuk Sungai Lowatag yaitu 2, 94Rivers have important role for humans and wildlife. Macrozoobenthos occupies habitat at the bottom of the rivers. Biodiversity of macrozoobentos is important in river ecosystem. This study aimed to analyze biodiversity of macrozoobenthos of Lowatag River based on the Shannon-Wiener Diversity Index (H’). This study used a purposive random sampling method along Lowatag River. There were three research stations, namely upstream, middle and downstream with three replications each station. Macrozoobenthos found in the Lowatag River have total abundance of 1,115 individuals (35 taxa). The abundance of macrozoobenthos at Station I, II, and III were 26.37%, 44.39% and 29.24% respectively. The Shannon Diversity Index (H ') values of Station I, II and III respectively were 2.97; 2.69; and 2.61. The H’ value of Lowatag River was 2. 94

Abstract

Fauna tanah menggunakan tanah sebagai habitat alami untuk keberlanjutan hidupnya. Aktivitas pertanian yang menggunakan pupuk dan pestisida dapat menjadi penyebab penurunan keanekaragaman fauna tanah. Penelitian ini bertujuan untuk menganalisis keanekaragaman fauna tanah pada agroekosistem tanaman tomat (Solanum lycopersicum L.) di Desa Raringis, Langowan Barat, Minahasa, Sulawesi Utara. Pengambilan sampel dilakukan di lima stasiun pada Desember 2018 – Januari 2019 dengan metode purposive sampling dengan pitfall trap. Fauna tanah yang ditemukan di agroekosistem tanaman tomat terdiri atas tiga filum, delapan kelas, 19 bangsa, dan 36 suku. Total fauna tanah sejumlah 41 taksa.  Keanekaragaman fauna tanah berdasarkan Indeks Shannon- Wiener (H’) berturut-turut dari Stasiun I, II, III, IV dan V yaitu 1,93; 2,02, 2,04, 1,97 dan 2,06. Indeks keanakeragaman fauna tanah di Desa Raringis tergolong sedang (H’: 2,00). Keanekaragaman fauna tanah dipengaruhi oleh faktor-faktor lingkungan misalnya suhu tanah, curah hujan, penggunaan pupuk kimia, pestisida sintetik dan pola penanaman tomat secara monokulturSoil fauna occupy soil as their natural habitat for their sustainability. Agricultural activities that use fertilizers and pesticides can cause decrease in the diversity of soil fauna. This study aimed to analyze the diversity of soil fauna in the tomato agroecosystem (Solanum lycopersicum L.) in Raringis Village, West Langowan, Minahasa, North Sulawesi. The soil fauna sampling was conducted at five stations in December 2018 - January 2019 with a purposive sampling method with pitfall traps. Soil fauna found in the agroecosystem of tomato plants consisted of three phyla, eight classes, 19 orders, and 36 families. Total soil fauna tanah was 41 taxa. The diversity of soil fauna based on the Shannon-Wiener Index (H ') respectively from Stations I, II, III, IV and V were 1.93; 2.02; 2.04; 1.97 and 2.06. The index of diversity of soil fauna in Raringis Village was classified as moderate (H ': 2.00). The diversity of soil fauna was influenced by environmental factors such as soil temperature, rainfall, chemical fertilizers, synthetic pesticides and tomato monoculture farming
