Judul: Study on supplier selection and evaluation  in paper supply chain
Abstrak: Over the last decade a major change has stricken pulp and paper industry. Increasing demand, more selective raw materials acquisition, and more competitive environment of the industry are three leading dimension that fill the change. In such condition, all actors involved in pulp and paper industry are required to pay more attention in their functions and activities to run effectively and efficiently. Supply chain management (SCM) is an approach through which such this objective can be achieved. In SCM perspective, inter-parties integration becomes a necessity to deal with any conflicting objective between different functions. In line with this, a good relationship with suppliers could ultimately improve competitiveness of the entire supply chain. Selecting right suppliers is the first strategic decision that determines the success in implementation of SCM. It plays a key role in any organization because it significantly reduces the unit price and improves corporate competitiveness. Furthermore, emphasis on quality and delivery, beside of cost consideration, in today’s globally competitive market adds the complexity of supplier selection decision.

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: Morphometrics and Body Weight Gain of Female Tokay Gecko (Gekko gecko) at Different Temperatures
Abstrak: Tokek rumah (Gekko gecko) adalah salah satu reptil yang tersebar di hampir semua pulau di Indonesia. Tokek adalah hewan pemakan serangga dan hewan arboreal. Sebagai makhluk ektotermik, Tokek menggunakan suhu sekitar untuk mendukung aktivitas makan dan metabolismenya. Penelitian ini bertujuan untuk menganalisis pengaruh suhu yang berbeda terhadap morfometrik dan pertambahan bobot badan tokek rumah betina. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan suhu yang berbeda, yaitu P1 (27,0-28,9 ?), P2 (29,0-30,9 ?), dan P3 (31,0-32,9 ?). Setiap perlakuan terdiri dari 4 ulangan, sehingga total terdapat 12 tokek rumah betina dengan rentang berat badan 45-65 g. Peubah yang diamati meliputi panjang ekor, panjang tubuh, panjang lengan atas, panjang paha, panjang total, panjang moncong sampai kloaka, dan berat badan. Perbedaan suhu tidak berpengaruh nyata terhadap morfometrik tokek rumah betina tetapi berpengaruh nyata (P<0,05) terhadap bobot badan. Suhu 29,0-30,9 ? memberikan pertambahan bobot badan (7,79±3,84 g) yang cukup tinggi dibanding dengan perlakuan suhu 27,0-28,9 ? dan 31,0-32,9 ?., The Tockay gecko (Gekko gecko) is one of the reptiles found on almost every island in Indonesia. Geckos are insectivorous and arboreal animals. As ectothermic creatures, geckos use the surrounding temperature to support their feeding activity and metabolism. This study aimed to analyze the effect of different temperatures on the morphometrics and weight gain of female house geckos. The study used a Completely Randomized Design (CRD) with three different temperature treatments: P1 (27,0-28,9 ?), P2 (29,0-30,9 ?), and P3 (31,0-32,9 ?). Each treatment consists of 4 replications, resulting in a total of 12 female house geckos with a weight range of 45-65 g. The observed variables included tail length, body length, forelimb length, thigh length, total length, snout-to-vent length, and body weight. The temperature differences did not significantly affect the morphometrics of female house geckos but did significantly affect (P<0.05) their body weight. The temperature of 29,0-30,9 ? resulted in a relatively high weight gain (7,79±3,84 g) compared to the temperature treatments of 27,0-28.9 ? and 31,0-32,9 ?.
