Judul: Pemilihan Pemasok Berdasarkan Kualitas Bahan Baku dalam Supply Chain Network dengan Integer Linear Programming
Abstrak: Supplier is a provider of raw materials needed by company to produce goods and services. Raw materials shipped from supplier to manufactures have different qualities. The quality of raw materials affects purchasing costs for raw materials and reprocessing cost in manufactures. Raw material with high quality does not require reprocessing but its purchasing price is higher than other raw material. Although their purchasing prices are lower, raw materials with medium or low quality still need reprocessing. In this manuscript, supplier selection problem is formulated in term of integer linear programming, where the objective is to maximize the company profit. As an implementation, we considered a Noodle XYZ company with supply chain consisting of 5 potential suppliers, 3 manufactures, 3 warehouses, and 4 customers. The company selects suppliers based on the quality of raw materials offered, cost of hired suppliers, and distribution of the product. The optimal solution is obtained in term of suppliers to be selected and distribution of the product which maximizing profits.

Judul: Berat Badan Dan Morfometrik Leopard Gecko (Eublepharis Macularius) Pada Berbagai Umur
Abstrak: Leopard gecko (Eublepharis macularius) adalah jenis tokek yang hidup di permukaan tanah dan aktif saat fajar dan senja. Studi morfometrik dalam leopard gecko masih terbatas. Tujuan dari penelitian ini adalah untuk mengukur dan membandingkan berat badan dan morfometrik leopard gecko dari berbagai umur. Sebanyak 14 ekor leopard gecko (3 ekor jantan dan 11 ekor betina) dikelompokkan menjadi empat kelompok: 0-6 bulan, 7-12 bulan, 13-18 bulan, dan 19-24 bulan. Pengukuran dilakukan setiap bulan selama tiga bulan sehingga hewan dapat ditimbang dan diukur lebih dari sekali. Selama 90 hari pascatetas, pengukuran berat dan panjang dilakukan setiap hari, dua hari, atau setiap minggu tergantung dengan tingkat pertumbuhan. Hasil penelitian menunjukkan bahwa kelompok umur 0-6 bulan memiliki berat badan 10.69±5.68 g dan total panjang 12.79±3.68 cm; 7-12 bulan memiliki berat badan 16.57±4.52 g dan total panjang 16.7±1.23 cm; 13-18 bulan memiliki berat badan 21.12±3.13 g dan total panjang 19.4±1.15 cm; dan 19-24 bulan memiliki berat badan 27.9±1.53 g dan total panjang 20.8±1.51 cm. Dapat disimpulkan pada leopard gecko kelompok umur 0- 6 bulan memiliki pertumbuhan yang lebih bervariasi pada berat badan, panjang kepala, panjang kaki belakang, dan panjang ekor dibandingkan dengan yang lain.
