Judul: Model penjadwalan produksi di PT.Gasandry, Bogor
Abstrak: Penjadwalan produksi merupakan suatu unsur yang penting dalam perencanaan produksi pada suatu industri. Dalam hierarki pengambilan keputusan, penjadwalan merupakan langkah terakhir sebelum dimulainya proses produksi. Banyak perusahaan mengalami permasalahan tidak dapat merealisasikan pengiriman barang tepat pada waktunya, banyak pekerjaan terlambat, overtime, dan jumlah stasiun kerja yang menganggur. Hal ini akan menyebabkan terjadinya pemborosan aktivitas maupun biaya produksi. PT.Gasandry (GS) Bogor merupakan perusahaan yang bergerak dalam industri minuman kemasan yaitu industri kopi. Banyaknya waktu menganggur (idle time) yang terdapat pada lantai produksi PT. Gasandry menjadi salah satu masalah penjadwalan produksi. Untuk mencapai utilitas dan efektifitas produksi, maka diperlukan adanya pengaturan mekanisme terhadap rangkaian aktifitas. Aktifitas-aktifitas tersebut terdiri dari aktifitas transformasi bahan baku dengan urutan tertentu, penggunaan fasilitas mesin, peralatan dan tenaga kerja. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang terkait dengan penjadwalan di perusahaan dan mendapatkan model penjadwalan produksi yang sesuai dengan kondisi dan karakteristik perusahaan. Metode yang digunakan dalam penelitian ini adalah metode heuristik yang merupakan pengembangan dari proses aritmatika dan matematika logika. Penggunaan metode ini di anggap mampu untuk mengefektifkan penjadwalan produksi di PT Gasandry. PT.Gasandry memproduksi 6 jenis produk yaitu kopi jahe susu, kopi susu, kopi moka, kopi instan, kopi gula dan gula jahe. Terdapat 3 jenis proses produksi kopi kemasan di PT.Gasandry yaitu melalui tahapan penggilingan, tidak melalui tahapan penggilingan dan proses produksi yang hanya melalui proses pengemasan…

Judul: Model Penjadwalan Produksi Di PT. Gasandry, Bogor.
Abstrak: Production scheduling is an important element in industry planning production. In the hierarchy of decision making, scheduling is the last step before the commencement of production. Many companies have problems to deliver goods on time, late of work, overtime, and the number of idle workstations. All these will lead to wasteful activities and the high production cost. PT.Gasandry (GS) Bogor is a beverage packaging coffee company. Number of idle time is becoming one of the production scheduling problems. There should be mechanisms of activities to achieve an efficiency and effectiveness of production. Those activities consist of the transformation of raw materials with a particular sequence, use of machinery facilities, equipment and labor. This research is aimed to identify factors associated with the company scheduling and find the best production alternative scheduling model, which is appropriate with the conditions and characteristics of the company. This research is using heuristic method which is developed from the process of arithmetic and mathematical logic. This method is considered as a good method to streamline the production scheduling in PT Gasandry. PT.Gasandry is producing six products, such as ginger coffee milk, coffee milk, coffee mocha, instant coffee, original coffee and sugar ginger. There are three types in the coffee production process. They are milling process, without milling process and packaging process only. The result of this research is production scheduling model that can minimize the idle time. The model was called GSPS 1.0 (Gasandry Production Schedule) which had several models, consisted of product master model, a master model material, model master working days, production needs model, product model in and out of warehouses, enter the material model, material model and message scheduling model. GSPS 1.0 will help the production scheduling easier. For implementation purposes, GSPS 1.0 is an integrated system of a computer program Borland Delphi 7.0 as the software for user interfaces and Ms. Access 2007 as base data. From the result of scheduling that has been made, PT Gasandry will be able to optimize the working time of workers by reducing the number of workers to a maximum of 18 person / days of the initial 30 man / days in average of demand is 22.935 dozen/month. Production scheduling in PT.Gasandry is influenced by product varian, products demand, product tolerance store, production time, and capacity of packaging machinery. Critical factor in the preparation of production scheduling in PT.Gasandry is the capacity of packaging machinery.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
