The Asiatic softshell turtle Amyda cartilaginea (Boddaert, 1770) is one of the reptile commodities included in CITESAppendix II with vulnerable status according to IUCN. The species has been harvesting, especially for export purposein South Sumatera. The reseach was aimed to know the population characteristics of the Asiatic softshell turtleharvested in South Sumatera. The study was carried out based on enumerators approach from July to Desember2012 in South Sumatera. The data enumeration also has been collected from the 1st collectors. Data analysis includedthe size distribution of carapace curve length (CCL), carapace curve width (CCW), body weight, sex ratio, agestructure, CCL-weight relationship and von Bertalanffy growth parameters. The results showed that there wererecorded 306 individuals of A. cartilaginea (92% adult) with sex ratio male and female is 42:58. Its has carapacecurve length range from 10 to 75.5 cm, carapace curve width 9 to 59.5 cm and body weight 0.02 to 40 kg. A.cartilaginea growth pattern was negatively allometric (b = 2.727). The von Bertalanffy growth formula of A.cartilaginea in South Sumatera was PLK(t) = 78,75{1-exp[-0,18(t-(-0,72)]} cm.Keywords: Amyda cartilaginea, population characteristics, South Sumatera

The research aimed to identify the community structure and ecological status of the introduced fish in Lake Batur, Bali. The study was carried out on May, July and October 2011 using survey method. The fishes were obtained using experimental gill nets and by fishermen. Data analysis included index of diversity, evenness, dominance, species richness and the abc (abundance-biomass comparison) curve. The results showed the tilapia (Oreochromis niloticus) was the dominant species. The status of introduced fish community suggested to ecological stress but it was relatively undisturbed.

Presiden melalui Peraturan Presiden (Perpres) Nomor 59 Tahun 2019 tentang Tujuan Pembangunan Berkelanjutan. Ada tiga hal besar yang ditargetkan dalah satunya terkait Program Prioritas Nasional sesuai dengan kewenangan desa adalah yaitu pendataan desa, pemetaan sumberdaya dan pengembangan teknologi informasi komunikasi (TIK). Untuk itu, banyak Desa berrinovasi dengan menggunakan TIK dalam kegiatan pelayanan yang ada di Desa, salah satunya adalah layanan menggunakan Sistem Informasi Desa berbasis website. Saat ini, ada banyak sekali layanan Sistem Informasi Desa, baik yang diberikan secara gratis atau dikelola secara professional oleh perusahaan tertentu. Dan dengan adanya Sistem Informasi Desa ini, menjadikan salah satu indikasi Desa masuk kedalam katogori maju atau tidak. Desa Margo Mulyo adalah salah satu Desa yang menggunakan Sistem Informasi Desa (SID )dengan platform OpenSID yaitu layanan SID yang memiliki lisensi terbatas tetapi dapat dikembangkan oleh pengguna / Opensources. Namun beberapa kendala dihadapi oleh Desa pengguna layanan SID ini karena beberapa factor, diantaranya kemampuan dalam penggunaan teknologi, belum siapnya sarana dan prasarana, masalah jaringan, dan lain sebagainya. Untuk itu penulis melakukan penelitian Analisis Sentimen Opini Masyarakat Terhadap Penerapan Pelayanan Digital Di Desa Margo Mulyo Menggunakan Algoritma K-Nearest Neighbor dengan menggunakan kuisioner Google Form. Hasil analisis menggunakan Algoritma KNN menunjukkan memperoleh akurasi sebanyak 0.743333 masyarakat desa Margo Mulyo menyatakan opini mereka dengan data diperoleh data negatif 759, positif 498, dan netral 240. persentase sentimen positif: 33.27%, persentase sentimen negatif: 50.7%, persentase sentimen netral: 16.03%.
