Judul: Program Evaluasi Pemberian Pakan Sapi Perah Untuk Tingkat Peternak Dan Koperasi Menggunakan Microsoft Access
Abstrak: The demand on animal products increases in line with the increase in human population and their awareness on their nutritive value. Milk is a highly nutritive animal product which has high economic value. However, milk yield and its nutritive value are influenced by the nutritional status of the cows. Computer can be used as a tool to evaluate efficiently and accurately the nutritional status of dairy herd. In the present study, a computer program was developed using Microsoft Access by analyzing system, creating solution design, test and implementation program. System analysis and solution design were used to evaluate the nutrient requirement and reproduction status of the animal by entering the data of farmer identity (name, date and place of birth, education status, start of farming, animals ownership and address), animal identity (code, date of birth, physiology status body score and body weight), feeding aspects (feeding and nutrient requirement), and animal reproduction status (age at first calving, lactation period, lactation month and daily milk yield). The available data was used to evaluate the developed program. The output of the program indicated the ownership of the animal, population, nutritional and physiological status and milk yield. Key words: program, cows, feed, milk, farmer, cooperative

Judul: Analisis efisiensi produksi dan peran koperasi terhadap usaha ternak Sapi Perah di Kecamatan Cibungbulang Kabupaten Bogor
Abstrak: Indonesia has a potency to develops the dairy industry in the future, however Indonesia still imports about 73% of its dairy need and produces the 27% remaining domestically (Kementerian Pertanian, 2013). Kawasan Usaha Ternak (KUNAK) Cibungbulang, Bogor District is purposively established by the Koperasi Peternak Susu (KPS) Bogor as a national pilot area of an environmentally friendly dairy farm. Further, it is also expected that its milk production can support national milk supply. However, as the milk production in KUNAK Cibungbulang still highly depends on the input usage, therefore the influencing factors of milk production analyses are interesting to be examined. Moreover, this study also analyses the farmer’s income level, the optimum input usage, and also the dairy cooperative’s role in supporting the farmer’s activity. This study applies the double linear regression which has been transformed into the natural logarithm form, the farm management income analysis, the efficiency analysis of production factor, and the descriptive analysis. The result of the study indicates that the significant production factors which influence the milk production are: the amount of the feed, concentrate, tofu dregs, and workers. The analysis is resulting an evidence of profitable dairy farm. However, it is also important to increase the usage of optimum input and the cooperative roles, thus the KUNAK Cibungbulang can reach its optimum profit. The research found that inputs farm have not been used optimally, even the dairy cooperatives have supported the farms well.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
