Judul: Produktivitas Kerbau Rawa di Kecamatan  Muara Muntai, Kabupaten Kutai Kartanegara, Kalimantan Timur
Abstrak: The purpose of this reseach was to investigate productivity of swamp buffalo in Pulau Harapan Village. The reseach was conducted from February to May 2009 in Muara Muntai Subdistric, Kutai Kartanegara Regency, East Kalimantan. The number of observation were 16 buffaloes (bull, dam, male and female calves 4 each). The results were as follow: the ratio between male and female was 1:4; first oestrus was at 2.6 years of age with the average duration of heat about 8 days and the oestrous cycle about 18.5 days. The first conception occured at 2.8 years with the gestation period about I year. Birth rate and calf crop were relatively high: 75% and 67%. The difference of birth rate and calf crop caused mortality about 11% at 1.7 months of age. Service per conception and conception rate were not known because the buffalo does not use artificial insemination and natural mating was not controlled by breeder. An average body weight of calves at 0 to 24 months were 201.58±81.27 kgs and adult buffaloes at 3-10 years were 372.66±95.25 kgs. The development prospect of buffalo in Muara Muntai was analysed with SWOT from internal and external aspects. Internal aspect include livestock land natural resource, man power, institution, and maintenance system, whereas external aspect include climate, meat demand, price, rivalry, sociocultural, and socioeconomy. The strategies formula of development livestock based on the result of SWOT analysis are reduced mortality, increasing productivity of forage with high quality, increasing harvest weight, repairing reproduction aspect, and deciding prohibition order disimissal and slaughtering breed of bufallo.

Judul: Produktivitas, Potensi Dan Strategi Pengembangan Kerbau Belang Di Kecamatan Sanggalangi’, Kabupaten Toraja Utara, Sulawesi Selatan
Abstrak: Spotted buffaloes (Tedong Bonga) is one of local livestock that has the highest value in Torajan’s culture. Population of Torajan's spotted buffalo has been decreasing since several years ago. The aim of this research was to analyze the productivity and reproductivity performances of Torajan’s spotted buffalo. Secondly, to analyze how the potency and development strategy of Torajan's spotted buffalo in Sanggalangi subdistrict, North Toraja. This research was conducted from July to September 2010 in the Sanggalangi’ subdistrict, North Toraja District, South Sulawesi. This research used sampling method were purposive sampling method for subdistrict samples and farmers samples ( 90 farmers). Two kinds of data were obtained in this research. The primary data was collected from the farmers by interview using questioner and observation. The secondary data was collected from North Toraja Livestock and Fishing Departement, Central Statistics Departement, Agricultural Departement and Subdistrict Departement. Data collected were analyzed with descriptive analysis, reproduction characteristic analysis, dynamics of buffalo population analysis, Capacity of Additional Ruminant Population (CARP) analysis, and SWOT (strength, weaknesses, opportunities, and threats) analysis. The result showed that as follow : the ratio between male and female was 1:3; first oestrus was at 2,48 years of age with the average duration of heat about 22,6 hours and the oestrous cycle about 18.5 days. The first conception occured at 2.87 years with the gestation period about 387,4 days. Birth rate and calf crop were relatively high: 89% and 77%. The difference of birth rate and calf crop caused mortality about 2,35%. Service per conception (S/C) was 1,85 time and conception rate was 86,5%. CARP estimation showed that Sanggalangi’ subdistrict’s CARP value was negative. The strategies formula of development spotted buffalo is turnaround strategies or stability of weaknesses and opportunities.

Judul: Karakteristik Kristal Fotonik Satu Dimensi dengan Apodisasi Menggunakan Piranti Lunak C++
Abstrak: Cahaya merupakan gelombang elektromagnetik ( EM ) memiliki perambatan radiasi dalam kristal fotonik yang menarik untuk dipelajari dan memiliki banyak kegunaan dalam kehidupan. Metode yang digunakan yaitu analisis grafik yang dihasilkan piranti lunak c++. Piranti lunak yang digunakan yaitu hasil karya sendiri yang menggunakan bahasa pemrograman c++. Pada penelitian ini, ditemukan pola transmitansi kristal fotonik dengan apodisasi. Pada kontras indeks bias yang tinggi, pola yang diperoleh berbeda dengan pola transmitansi kristal fotonik regular. Pola transmitansi apodisasi simetris kecil ke besar bersifat transmiter yaitu dapat mengangkat band gap , mengangkat side lobe, mengurangi jumlah side lobe, dan memperlebar band gap. Sementara itu, pola transmitansi apodisasi simetris besar ke kecil bersifat reflektor bahkan dapat menghilangkan band gap. Pada kondisi tertentu, diperoleh hasil grafik yang menggambarkan side lobe yang datar. Fenomena ini dapat dimanfaatkan untuk optimasi side lobe.
