Abstract

This study aims to calculate the value of the abundance of macrozoobenthos in the Intertidal Musi River Estuary in Sungsang Village, Banyuasin II District, Banyuasin District, South Sumatra Province and to analyze the effect of water salinity on macrozoobenthos in Intertidal Musi River Estuary, Sungsang Village, Ba-nyuasin II District, Banyuasin District, South Sumatra Province. The study was conducted from January 2018 to August 2018, at the Laboratory of Ecology, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University, Indralaya. This study includes the test of morishita index and correlation. The results of the study were 4 genera from Bivalvia class, 4 genera from Gastropod class, and 2 families from Poly-chaeta class. The macrozoobenthos abundance in the intertidal Muara Sungsai Musi ranged between 456-854 ind/m2 and the morphic index of each station was included in the grouping and random criteria. Based on the analysis between abundance and salinity, the bottom coefficient (r) is equal to 0.943 which is very strong be-tween salinity and abundance.

Abstract

Musi River Sungsang Village which is located near the settlement makes people throw garbage into the sea during high tides so that it will affect water quality and have an impact on macrozoobenthos. It is im-portant to know the diversity of macrozoobenthos in the waters of the Musi River in Sungsang Village, South Sumatra. This research was carried out from January 2018 to August 2018 in the Musi River in Sungsang Vil-lage, South Sumatra by using the method of direct observation and randomized group design. The research location was determined by purposive sampling method and divided into 4 stations, each station had 1 line transect and each line transect was taken as many as 10 samples. ANOVA, overley and correlation analysis are used to process data. Based on research conducted in the Musi River in Sungang Village, there were 14 ma-crozoobenthos taxa consisting of 3 classes: bivalves, gastropods and polychaeta. Index of macrozoobenthos di-versity in Musi River in Sungsang Village is classified as ranging from 0,000 – 1,733. Organic matter does not af-fect macrooobenthic in the Musi River in Sungsang Village, South Sumatra

Abstract

Waders migrate to maintain survival, to find new food sources and avoid extreme environmental changes. Waders population in a location varies according to environmental conditions. The study was con-ducted using the point count method. The observation time of each location is 30 minutes with repetition 3 times. There are four observation locations, namely Bungin River Estuary, Solok Buntu Estuary, Barong Kecil River Estuary, and Siput River Estuary. Data analysis technique uses correlation analysis. The results showed the number of wader birds at the end of the season migration in the Siput River Estuary was 886 individuals, while the Barong Kecil River Estuary was 536 individuals, Bungin River Estuary 140 individuals, and Solok Buntu Estuary 105 individuals. Tringa totanus, Limosa laponica, and Numenius arquata can be found at each observation location. Wader birds population found correlated with macrozoobenthos density had a correla-tion coefficient of 0.73.

Abstract

Pakan ikan berbasis tepung maggot merupakan salah satu solusi untuk mengatasi kelangkaan dan tingginya harga pakan ikan komersial. Kegiataan pengabdian ini bertujuan untuk  melakukan pelatihan, pendampingan dan mmelatih ketrampilan khalayak sasaran  dalam membuat pakan ikan berbasis tepung maggot BSF Hermentia illucens.  Kegiataan ini  diikuti oleh 27 ibu-ibu kelompok PKK. Kegiataan ini menggunakan metode penyuluhan, pembimbingan dan demontrasi dan pelatihan seperti teknik pemeliharaan, pembuatan media tumbuh maggot, teknik pemanenan dan teknik pembuatan tepung BSF serta pembuataan pakan ikan. Kegiataan ini memberikan hasil yang memuaskan dilihat dari semangat dan antusias peserta dalam bertanya dan dari hasil quisioner yang diberikan. Terjadi peningkatan pengetahuan peserta dari yang tidak tahu menjadi mengerti dari 60-100 %. Peserta dapat melakukan teknik pemeliharaan maggot, pembuataan tepung dan percetakkan pakan sebanyak 60 sampai 100 %, Tingkat kepuasaan akan produk meliputi kurang suka, suka dan sangat suka terhadap  bentuk, bau dan manfaatnya berkisar antara 20-90%. Kegiataan ini ternyata telah  memberikan tambahan ilmu pengetahuan dan pemahaman serta membuat khalayak sasaran trampil dalam membuat pakan ikan berbasis tepung  maggot BSF, ada keinginan kuat dari peserta untuk membuat pakan ikan berbasis tepung maggot secara mandiri.
