ASOSIASI KERANG LOKAN (Geloina erosa) PADA EKOSISTEM MANGROVE DI TANJUNG UNGGAT KECAMATAN BUKIT BESTARI KOTA TANJUNGPINANG

Kerang Lokan (Geloina erosa) merupakan salah satu biota yang hidup pada ekosistem mangrove. Ekosistem mangrove di Tanjung Unggat telah mengalami pengurangan luasan diakibatkan aktivitas manusia seperti pemukiman, transportasi kapal, aktivitas bongkar muat, aktivitas galangan kapal dan reklamasi. Penelitian ini dilaksanakan pada bulan Februari – Mei 2020 pada ekosistem mangrove di Tanjung Unggat Kecamatan Bukit Bestari Kota Tanjungpinang. Penelitian ini bertujuan untuk mengetahui asosiasi Kerang Lokan (Geloina erosa) pada ekosistem mangrove. Penentuan titik sampling diambil dengan metode purposive sampling sedangkan pengambilan data vegetasi mangrove digunakan transek garis sepanjang 50 m dengan transek 10x10m (Pohon), 5x5m (Anakan) serta pengambilan sampel Kerang Lokan diambil dengan menggunakan plot 5x5m didalam area mangrove. Hasil penelitian menunjukkan bahwa kerapatan mangrove di Tanjung Unggat tergolong jarang dan terdapat 8 jenis mangrove (Avicennia lanata, Rhizophora apiculata, Sonnetaria alba, Rhizophora stylosa,  Rhizophora mucronata, Bruguiera parviflora, Xylocarpus granatum dan Avicennia alba). Kerang Lokan berasosiasi pada mangrove dan jenis substrat di lokasi penelitian. Kata Kunci : Asosiasi, Geloina erosa, Mangrove, Tanjung Unggat

Pemanfaatan Kulit Ari Kedelai sebagai Bahan Pembuatan Nugget untuk Peningkatan Gizi Anak Stunting: Soybean Husk as the Nugget Basic Ingredient to Improve the Nutrition of Stunting

Reducing the incidence of stunting in Indonesia is a top priority in overcoming health problems. Mesjid Ward, Samarinda City, is one of the areas that has a high prevalence of stunting, with as many as 34 children in 2020. Efforts to overcome this problem need to use unconventional food ingredients that contain adequate nutrition, are affordable, and are easy to obtain. Soybean husk, which has a high protein and fiber content, has the potential to be utilized in efforts to fulfill stunting children's nutrition. Community service activities aim to increase the utilization of soybean husk as processed healthy nuggets, increase public knowledge regarding stunting, and improve community skills in processing soybean husk-based nuggets—activities carried out by providing counseling and training. The results of this activity indicated that there was a significant change in the community's knowledge after giving the material (p-value <0.001). The knowledge about stunting and how to use soybean husk in processed food products has increased among the public
