Abstract

An experiment was done at Cage Rabbit Trial and Laboratory of Animal Husbandry, Departement of Animal Husbandry, The State of Politechnic Lampung. The first experiment began in 10th until 30th July 2010. The second experiment began 27th August until 15 September 2010.The first experiment were conducted to know some treatments to made cassava leaf meal silage. The second experiment to know dry matter, crude protein, and crude fibre digestible on using of the cassava leaf meal silage in male local rabbit. The treatment and method two steps by used: In experiment 1, P1= 0% corn meeal, P2= 5% corn meal, P3= 10% corn meal, and P4=15% corn meal. In experiment 2, These used 16 male local rabbit. The rabbit were placed randomizely in battery cage. Parameter measured were : dry matter, crude protein , and crude fibre digestile. The nutrient digestibility determined by Harris (1983). The result of this experiment showed that ensilage processing increased quality of nutrien conten and its digestibility on local rabbit.. Keywords : Silage of cassava leaf meal, local rabbit, digestibility

Abstract

Gisting Dairy Farm (GDF) merupakan UMKM, bergerak dalam usaha sapi perah di Desa Sidokaton Gisting, Tanggamus dan dikelola secara mandiri. System pemeliharaan sudah tertata dan tersedia sumber air bor yang setiap saat digunakan untuk pembersihan kandang dan memandikan sapi. Populasi saat ini 41 ekor (25 ekor sapi dewasa). Jika rata- rata per ekor sapi menghasilkan feses 15 - 20 kg setiap hari, artinya akan dihasilkan 615 – 1.230 kg kotoran sapi per hari (224.475 – 448.950 kg/tahun), belum termasuk urin dan air memandikan sapi dan membersihkan kandang yang dilakukan setiap hari. Dengan lahan yang sangat terbatas, usaha ternak sapi perah GDF sangat berpotensi mencemari lingkungan disekitarnya. Tidak optimalnya pengolahan limbah disebabkan :1) Minimnya pengetahuan SDM Gisting Dairy farm mengenai pengelolaan limbah, kaitannya dengan perbaikan kualitas lingkungan. 2) SDM Gisting Dairy Farm belum mengetahui model dan teknologi pengolahan limbah dan manfaat pengolahan kaitannya dengan produksi bersih usaha sapi perah; 3) SDM Gisting Dairy Farm belum mengerti mengolah limbah menjadi pupuk organik maka perlu dilakukan pendampingan. Solusi yang ditawarkan : 1) Mensosialisasikan model dan teknologi pengolahan limbah dan manfaat pengolahan kaitannya dengan produksi bersih usaha sapi perah; 2) Merancang dan membuat model pengelolaan limbah di GDF; 3) Mendemonstrasikan pengolahan limbah menjadi pupuk organic dan membuat demplot percontohan tanman hijauan pakan ternak. 4) Melakukan pendampingan dalam proses penerapan/implementasi produksi bersih melalui pengelolaan terpadu limbah yang diproduksi pada usaha mitra, disertai dengan evaluasi. Berdasarkan hasil dan pembahasan dapat disimpulkan bahwa : (1) Pemahaman SDM mitra terkait produksi bersih pada usaha sapi perah meningkat; (2) SDM mitra mampu mengoah limbah menjadi pupuk organic (kompos); (3) Terjadi perbaikan lingkungan yang signifikan melalui penerapan produksi bersih, limbah yang terbuang ke lingkungan menurun; (4) Implementasi produksi bersih pada usaha sapi perah di GDF mampu meningkatkan tanbahan pendapatan bagi sistem tersebut (B/C Ratio >0,12).

Abstract

Recently, the productivity of porang tuber-based products has been growing well, especially after the Indonesian Government released a policy to prohibit the export of porang plants and their harvested products. One of the porang-based products is in the form of chips. Before processing, the porang tubers must be washed thoroughly to remove soil/dirt from the surface. The conventional washing process of each tuber can take up to 3-5 minutes. Therefore, the purpose of this activity is to design and manufacture porang washing equipment based on centrifuge washing model with rubber vibration. Four stages to carried out the program, i.e. designed and manufactured the washing machine, run the machine in laboratory, training activities to the porang farmers, and evaluation process. From the observation to porang farmers as our partner during the activity, it can be seen that the partners can operate the washing machine well. The results show that the washing process of porang tuber using this technology can save the washing time up to 90% compared to the conventional washing. The surface cleanliness of porang tubers resulted from the developed washing machine is the same as the conventional one. The noise level of the machine has met the requirement of Indonesian Government. It is clear that the usage of  the machine can increase the production capacity of products-based porang tuber. In addition, the use of this technology may promote a more comfortable and healthy work environment due to ergonomic reason, however, based on RULA analysis, the machine is still need to be improved in the future. Overall, the partners were satisfied with this activity and expected to have further programs in the future.
