Distributional mapping and impacts of invasive alien fish in Indonesia : an alert to inland waters sustainability

Inland water ecosystems in Indonesia face an increasing threat of alien and invasive alien fish species. Their existence have been found in Indonesian waters since before 1900, and their introduction is rapid and ongoing. In this review, we mapped the distribution of alien and invasive alien fish in different inland waters ecosystem types and islands in Indonesia, based on available literature indexed by Google Scholar. Impacts of invasive alien fish and how to control them are also discussed. This data mining exercise resulted in the successful mapping of alien and invasive alien fish in 72 lakes and 57 river systems, covering 28 provinces. A total of 50 species have spread with different compositions in each type of ecosystem and island. Oreochromis niloticus is the most commonly encountered alien species. Moreover, invasive cichlid fish are most frequently found in lakes, while Pterygoplichthys spp. are more frequently found in rivers although they can also inhabit many lakes. Java Island is a hotspot of alien and invasive alien fish distribution, with 39 species reported. Invasive alien fish harm native and endemic fish in Indonesia through competition for food, space and direct predation. The gradual reduction of established populations of invasive alien species is necessary to protect Indonesia’s freshwater ecosystems

Perancangan Aplikasi Perpustakaan di SMK Negeri 10 Bekasi Berbasis Java Netbeans

Perpustakaan di sekolah-sekolah memilliki peranan yang sangat penting.  Terdapat beberapa perpustakaan yang masih memiliki kekurangan dalam pengelolaannya, salah satunya pada perpustakaan SMK Negeri 10 Kota Bekasi. Pada perpustakaan sekolah tersebut masih menggunakan sistem manual yaitu dengan menggunakan buku induk catatan secara tertulis sehingga pendataan anggota dan pendataan buku pada perpustakaan  SMK Negeri 10 Kota Bekasi masih belum terdata secara menyeluruh dengan baik. Proses pencarian buku serta proses transaksi peminjaman  dan pengembalian buku masih manual serta membutuhkan waktu yang cukup lama sehingga menyebabkan antrian dalam proses tersebut. Dalam pembuatan laporan masih menggunakan pencatatan dengan merekap data-data yang sudah ada, sehingga adanya  resiko kehilangan data karena kerusakan pada penyimpanan data dalam buku induk dapat terjadi. Tujuan dari penelitian ini yaitu merancang sebuah aplikasi perpustakaan yang terkomputerisasi. Dalam perancangan aplikasi perpustakaan pada SMK Negeri 10 Kota Bekasi ini menggunakan metode waterfall dengan menggunakan aplikasi java netbeans sebagai alat bantu pembuatan sistem informasi perpustakaan tersebut. Dari hasil penelitian diketahui bahwa aplikasi ini dapat membantu dan memudahkan petugas perpustakaan dalam proses pendataan anggota,  proses pendataan buku, proses transaksi peminjaman dan pengembalian buku serta proses pembuatan laporan
