ABSTRACT
East Java province is one of the development centre of dairy farming in Indonesia. In 2008, dairy farming activities in East Java constitue is about 88,148 dairy farmers, 29 dairy cooperatives, 130,000 dairy cows, and produces 600,000 litres freshmilk per day, from that amount 410,000 litres marketed to PT. Nestle. This study was conducted to analysis macro impact of milk district model Nestle on 1) labor absorption, natural resources conservation, and regional economic growth and 2) on capital assets accessibility of dairy farmers. Analysis methods that we used in this study were 1) field survey using questionnaire; 2) collecting secondary data; 3) in depth interview using checklist; and 4) measuring accesssibility on livelihood assets (human, natural, physics, social and financial accesss). Areas of study located on three regencies in East Java Province: Malang, Blitar and Kediri, 97 smallscale dairy farmers were surveyed. The impacts of milk district model on livelihood assets accessibilities remain significants especially on financial and social capitals. This means that dairy farmers accesssibilities on financial sources were improved because it provide regular source of income, something the dairy farmers would not receive from their seasonal crops. Accessibility level of social capital were improved too, this means that smallscale dairy farming activities capables to create many collective activities on the rural communities based on dairy farming issues through variety efforts on Artificial Insemination (AI), feeding process, freshmilk handling, freshmilk collecting, forages management, breeding, animal healthcares, etc. Accessibility level on human, physical and natural capitals remainds lower than social and financial capitals because there are a lack of human capital (knowledge, skills, creativity and adaptive strategy); a lack of physical capital (rural infrastructures); and natural capital (clean water availability).

Keywords:livelihood assets, milk district model, smallscale dairy farming

ABSTRACT
During for the past 10 years, milk production in Indonesia has been on the increase of approximately 70% (FAO, 2002), but it can only meet 30% of domestic needs for milk. The remaining 70% is still imported, mostly from  Australia and New Zealand. Milk production in Indonesia is expected to increase to achieve an average of 15-20 liters/cow/day.  It is necessary to analyze dairy enterprises to assess its feasibility. The objectives of this study were: (1) to evaluate production technology of small holder dairy farm in  West Java, Central Java and East Java;  (2) to analyze the efficiency of the existing dairy farming. Twenty farmers from each localities with ownership less than or equal to 10 cows, consisted of small (<4 cows), medium (4-6 cows), and large (> 6 cows) scales were interviewed on their  businesses. Economic analysis on net profit indicated by BC-Ratio, and IRR values. The dairy farming in West Java, Central Java and East Java was carried out traditionally without technological diversification, the main products were pasteurised fresh milk. Milk production was low (10 liters/cow/day). Net income of Rp 1,521,820/m/farmers, BC-Ratio 1.32,  and IRR  17% indicated a low result. Improving cows ownership should be in line with the improved management and technology application.

ABSTRACT

         In response to the failure of the Green Revolution which led to leveling off land productivity, damage the environment, and income of farmers who did not turn up, then introduction the sustainable agriculture development, namely how to manage farms to maintain long-term stability of ecology, biodiversity and improving local wisdom through integrated farming, biotechnology , holistic management, organic farming, animal husbandry based on the principles of animal welfare, food safety and other organics.
The insistence of global issues concerning animal walfare, back to nature, low fat, low cholesterol, presence of residual effects, antibiotics, hormones and other additives in food, can direct our movement towards organic poultry, especially with the utilization of native chicken, because potential indigenous chicken and maintenance system is suitable for conversion into the provision of organic chicken production in accordance to environmental sustainability without using feed ingredients which are modified gene.
Facing the era of organic poultry, local chicken can be relied upon by Indonesia in the future because it has many advantages; great potential and wide spread among the farmers, have the power of adaptation to local environments is high, tolerant of low quality feed, more tolerant to disease, however; productivity is still low, there is no adequate system poultry breeding. Through an integrated farming organic poultry feed ingredients in the environment can take advantage of farmers, non-conventional waste; earthworms, slugs, snails, waste oil, cattle (rumen contents), forestry, and other nutritious enough.
Required number of strategies for the development of local and broiler chickens on a small scale as organic poultry in the future, namely; immediately apply Permentan No. 49/2006 regarding poultry breeding, empowerment of farmers will add value compared to traditional organic poultry, lack of regulation and control of organic poultry, there is need for an organic chicken farmer associations as container consultancy, mentoring, education, technological innovation, joint marketing, and protecting the interests of members , as well as empowerment and awareness by consumers willing to pay more to the advantage of organic chicken.
Key words; sustainable livestock farming, organic food, integrated farming, organic poultry.

ABSTRACT

The Pesisir cattle are indigenous West Sumatera cattle. Their quality needs to be improved since they can live in local environment with sufficiently available feed resources. A research has been done to study the effects of feeding level and fattening period to the growth and the carcass characteristics of the Pesisir cattle. This research was designed by using block design with three blocks. The first factor was two levels of feeding, i.e: A1 = 50 % concentrate + 50 % ammoniated rice straw, A2 = 75 % concentrate + 25 % ammoniated rice straw. The second was time period of fattening, i.e: B1 = 3 months and B2 = 4 months. The results showed that there was no interaction between the level of feeding and fattening period to the growth, percentage of carcass, the back fat thickness and the rib eye area of the Pesisir cattle (P> 0.05). The higher of concentrate percentage, the higher the growth of the cattle, the thicker the back fat and the wider the rib eye area will be (P<0.05). Similarly, the longer the fattening, the higher the percentage of carcass, the thicker the back fat and the wider rib eye area will be.

ABSTRACT
The research purpose was analyzed the utilization of production factors in dairy cow farming in economies of scale at Ompie dairy cow farming in Tanjung Bonai village, North of Lintau Buo subdistrict, Tanah Datar regency. The samples were 18 lactating dairy cows. Data obtained through case study by observing and calculated the consumption of grass and concentrate as well as the lactating month and the cow’s weight directly, and interviewed Farm’s caretaker. Production factors estimated by using ordinary least square by using SPSS 17. Result shown, production function Y= 0,0012 H1,671K0,405M-0,187W0,119 was obtained. R Square test determination, coefficient (R2) was 0.721, which was means 71,2% of production variation can be explained through green food variable, concentrate, month of lactation, and different cows’ weight. The F test showed that overall, independent variables has significant impact on milk production (P<0,01). The t test result showed that green foods variable and month of lactation has real impacts on level of trust 99% while concentrate and cow’s weight did not have significant impact. This farm is experiencing increasing return to scale which means increasing the amount of input will generate additional output with bigger proportion. We can observe this on Σbi value of 2,076.
