Judul: Model Perbaikan Penjadwalan Produksi di PT. MDS,Cikarang - Bekasi
Abstrak: Production scheduling is an important aspect to support the success of a manufacturing company in achieving the target of production planning and affects the implementation of the production process over a period of time. The amount of idle time in scheduling are considered less effective in the production line and detailed production scheduling becomes a problem to be solved with rearrangment of the daily activities in PT. MDS. Preliminary research results indicate that production scheduling in PT. MDS influenced by demand of products, stock products, a number of production, downtime of machine cause of change over time, the order of production scheduling, transportation delay between machines, and working time of machine. A Critical ratio method, the next grouping of products, and re-sequencing of production process with Shortest Processing Time method is the right method in response to a scheduling problem in PT. MDS. A Critical ratio method is useful to sort the product type, while the grouping of products and the Shortest Processing Time method useful to maximize the use of equipments as well as reducing of idle time. The results showed a decreased machine utilization of 64% to 60% and downtime of machine decreased to 5%.

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: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
