Judul: Analisis Neraca Air dan Pendugaan Erosi Taman Keanekaragaman Hayati di Pabrik Mekarsari PT Aqua Golden Mississippi - Sukabumi.
Abstrak: Sebagai upaya pengelolaan kelestarian sumber mata air dan keanekaragaman hayati, pabrik aqua di sumber mata air kubang membuat suatu kawasan penyangga sumber mata air berupa Taman Keanekaragaman Hayati. Tujuan dari penelitian ini adalah mengetahui neraca hidrologi, mengetahui besarnya erosi di Taman Kehati. Simpanan air tanah diketahui dengan model SWAT, dan erosi dengan metode MUSLE. Taman Kehati Mekarsari memiliki ratarata aliran pemukaan 721.0 mm/tahun. Resapan rata-rata pertahun sebesar 1468.8 mm/ha. Perubahan simpanan air tanah di Taman Kehati Mekarsari mengalami fluktuasi dengan rata-rata perubahan simpanan air tanah sebesar 304.6 mm/tahun atau 1 ha mampu menyimpan 3046 m3. Laju erosi di Taman Kehati 4.8 ton//ha/tahun sehingga Taman Kehati sangat efektif dalam penurunan laju erosi.

Judul: The Role of Mekarsari Biodiversity Park as a Wildlife Habitat in Sukabumi District, West Java
Abstrak: PT Aqua Golden Mississipi pabrik Mekarsari merupakan industri air minum dalam kemasan yang telah membangun Taman Keanekaragaman Hayati (Kehati) tahun 2012 dengan tujuan konservasi tumbuhan langka dan perlindungan mata air. Keberadaan taman kehati diharapkan mampu mengembalikan satwa yang hilang dan/atau mendatangkan satwa baru. Penelitian ini bertujuan untuk mengkaji peran taman kehati sebagai habitat satwa liar dengan inventarisasi satwa berdasarkan taksanya. Penelitian ini dilaksanakan di Taman Kehati Mekarsari pada bulan Mei-Juni 2018. Alat yang digunakan adalah termometer dry wet, GPS, kamera, kamera jebakan, binocular, pita ukur, Arcgis 10.5 dan microsoft office. Analisis data dilakukan untuk memperoleh struktur dan komposisi vegetasi, indeks keanekaragaman, indeks kemerataan vegetasi dan satwa liar, serta status perlindungan satwa liar. Hasil penelitian ditemukan 23 spesies tumbuhan dari 15 famili. Satwa liar ditemukan 21 spesies yang terdiri dari 5 mamalia, 9 burung dan 7 herpetofauna. Terdapat 2 spesies satwa yang dilindungi oleh PP Nomor 7 Tahun 1999, dan 2 spesies yang masuk kategori Appendix CITES., Aqua Golden Mississipi Inc, Mekarsari factory, a bottled drinking water industry, has built a Biodiversity Park in 2012 with the aim of conserving rare plants and protecting springs. The existence of the park is expected to be able to return the lost wildlife and/or bring in new wildlife. This study aims to examine the role of the biodiversity park as a wildlife habitat by taking an inventory of wildlife based on their taxa. This research was conducted at Taman Kehati Mekarsari in May-June 2018. The tools used were dry wet thermometer, GPS, camera, camera trap, binocular, measuring tape, Arcgis 10.5 and microsoft office. Data analysis was carried out to obtain the structure and composition of vegetation, diversity index, evenness index of vegetation and wildlife, and wildlife protection status. The results showed 23 plant species from 15 families. Wildlife were found 21 species consisting of five mammals, nine birds and seven herpetofauna. There are two species that are protected by Government Regulation Number 7 of 1999 and two species that are included in the CITES Appendix.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
