Judul: Potential Area Producing Feed Supporting the Development of Cattle Population in Tanah Laut Regency
Abstrak: Forage has very important role as a ruminant feed that can not be replaced by the concentrate. Almost 90% of ruminant ratio comes from forage. There is a continuing conversion of forage producing areas into other uses resulting in the reduction of forage availability 30 %. Remote Sensing (RS) technology and Geographical Information System (GIS) can be used in agricultural mapping to manage natural resources in certain. This study aimed to identify the potential of areas producing feed and determine its availability in supporting the development of cattle population in Tanah Laut Regency. The showed 72,902 ha of the area including pasture (6,324 ha) maize field (25,622 ha), paddy field (40,956 ha) has potential to produce forage of 234,404 tons dry matter per year. One sub district in the regency was classified as moderate CCI area. The RS technology and GIS can be used to calculate feed availability development of cattle population. Tanah Laut regency has a potential capacity to accommodate more cattle population.

Judul: Ruminant Livestock Development Model in Tasikmalaya Regency Based on Feed Availability
Abstrak: Tasikmalaya Regency has not yet achieved beef independence because the demand for beef for consumption is higher than its production. Local farmers have not been able to meet these needs due to various factors, namely maintenance management and feed availability. The development of ruminants needs to be improved through the potential of natural resources and human resources so that both are in harmony and able to build beef cattle farms for the better. The purpose of this study was to analyze the natural resources and human resources owned by calculating the capacity factor of ruminant livestock in Tasikmalaya Regency. This study uses primary and secondary data obtained from observations, interviews, and analysis. Primary data was obtained from a survey of 43 beef cattle breeders, while secondary data was obtained from the Department of Agriculture, Food Security, and Fisheries of Tasikmalaya Regency. This study uses descriptive analysis and LQ (Location Quation) analysis, as well as a KPPTR (Capacity to Increase Ruminant Livestock Population) analysis which ends with a SWOT (Strength Weakness Opportunity Threat) analysis. From the results of the descriptive analysis illustrates if the supporting factors in the form of natural resources and human resources are closely related to the development of beef cattle in Tasikmalaya Regency. The results obtained through LQ analysis from 39 sub-districts there are 25 sub-districts with LQ<1 and 14 sub-districts with LQ>1, so it can be concluded that the 25 sub-districts are base areas with great potential for development areas, while the remaining 14 subdistricts are areas non-base with less potential for development areas. From the KPPTR analysis, it was found that the effective KPPTR value was 209,184.90 ST which illustrates that in Tasikmalaya Regency it is still feasible to add livestock according to the effective KPPTR value. SWOT analysis of internal and external factors obtained results in the form of group I with a KPPTR + value, LQ> 1 and group III with a KPPTR value -, LQ> 1 getting an aggressive strategy position that has high strengths and opportunities, while group II with a KPPTR + value, LQ<1 and group IV with KPPTR value -, LQ<1 are in a

Judul: Pengaruh kecepatan putar atomiser dan laju aliran terhadap karakteristik butiran pada atomiser piringan berputar
Abstrak: Penelitian ini didasarkan pada pentingnya karakteristik butiran dalam mempengaruhi mutu penyemprotan. Tujuan dari penelitian ini adalah mendapatkan pola hubungan antara kecepatan putar atomiser dan laju aliran semprotan dengan VMD butiran. Untuk pengamatan ini digunakan dua jenis piringan atomiser yaitu piringan terbuka dan piringan dengan penutup. Penyemprotan pada masing-masing piringan dilakukan dengan tiga tingkat laju aliran dan empat tingkat kecepatan putaran atomizer. Pola hubungan antar faktor dianalisa menggunakan analisis regresi berganda. Type piringan yang digunakan sangat mempengaruhi keragaman VMD butiran. Dengan menggunakan piringan terbuka didapatkan semprotan dengan VMD butiran yang lebih kecil dibanding jika menggunakan piringan tertutup. Tingkat keseragaman yang diperoleh relatif lebih baik dibanding pada piringan tertutup. Pada masing-masing piringan penyemprotan dengan beberapa tingkat kecepatan atomizer berbeda nyata pada selang kepercayaan 95%. Hubungan VMD butiran dengan kecepatan putaran atomizer menunjukkan korelasi negatif dengan tingkat penurunan yang semakin mengecil. Terhadap tingkat keseragaman butiran faktor N menghasilkan nilai ..dst
