Cattle Density Analysis for Development of Cattle Farming in Coconut Land Area in South Minahasa Regency, Indonesia

In an effort to develop livestock in a region in a developing country, it is necessary to analyze the potential of the area and density of livestock for the development of livestock business in a development area. This study aims to determine the potential of the region regarding cattle livestock density consisting of: economic density, farming density and regional density for the development of beef cattle farming in coconut plantations in South Minahasa Regency. The method used to carry out the analysis used livestock density analysis and analysis of regional potential using the primary and secondary data needed. The results of the study can be concluded based on the calculation of the combination of economic, farming and region densities, it is known that the sub-districts that receive the first priority in the development of beef cattle are the Sinonsayang and Amurang Barat sub-districts including the southern part of South Minahasa Regency, because this region can develop cattle farming and forage for both grasses and legumes in coconut fields which are mostly located in this region, which can be applied in an integrated manner through the coconut and beef cattle (coco-beef) integration system model. Whereas in Tatapaan Subdistrict and other sub-districts in the North and East regions of South Minahasa Regency it is not a priority for cattle development, because this region is more dominant with clove plantations and food crops such as paddy fields and other food crops. Keywords—cattle density, coconut land, farming.


I. INTRODUCTION
North Sulawesi Province, Indonesia sets coconuts as one of the leading commodities. The area of coconut plantation in North Sulawesi is around 270 thousand hectares (Marbun, 2014). Most of the coconut area is only cultivated in monoculture even though it has the potential of integration with livestock (Polakitan, 2012 andSalendua et al., 2018), even the land under coconut trees is only overgrown with vegetation for wild pastures both grass and local legume that grows wild, although the yield and quality of these types of forages are low and some of them are low edible for cattle, but due to lack of forages then the farmers are forced to feed or provide feed for local species ). The potential of livestock in South Minahasa Regency is quite adequate, especially cattle, where according to BPS data in 2016 there were 17,345 (BPS, 2017), as one of the largest areas and has the potential for cattle development because of the availability of land in the coconut area which can be used as land for forages and feed crops. Potential areas for developing cattle in South Minahasa Regency are in the area of extensive coconut plantations, which is the influence of the potential of the region on the capacity and density of cattle in the South Minahasa Regency. Through this research, it is expected to obtain findings and innovations, which consist of: (1) the density of cattle that is divided into three types, namely economic density, farming density and regional density; (2) the potential for developing forage crops in coconut fields; and (3) the potential of the region for the development of beef cattle business in coconut land areas in South Minahasa Regency. The research problems are as follows: (1) How is the level of cattle density divided into three types, namely economic density, farming density and regional density in South Minahasa Regency; (2) How wide is the potential of the development area of cattle in the coconut plantation area in South Minahasa Regency. The potential for developing livestock production, including farming the cattle-plant integration system, especially with plantation crops in Indonesia, is very large, supported by the potential of land resources for agricultural development, which is 100.7 million ha, which can feed biomass for cattle about 1-3 head / ha throughout the year. If not utilized, agricultural waste will become a problem and obstacle in agribusiness, because at the time of harvest it is wasted and becomes a polluter (BBLSBP, 2009). In addition, cow manure can be processed into bioslurry and biogas, according to Osak and Hartono (2016) that contribute to environmental sustainability is reduction in greenhouse gas emissions (GHG). Greenhouse gas emissions cause of global warming lately. Global warming is warming of the earth's atmosphere, due to accumulation principally of carbon dioxide and methane. Meanwhile, diversified systems according to FAO (2001) consist of components such as crops and livestock that coexist independently from each other.

MATERIALS AND METHODS This research was carried out on cattle farms in South Minahasa Regency, North Sulawesi Province, Indonesia, where 3 (three) sample sub-districts were selected which had the most cattle population in the East, Central and West regions, namely Sub District of Tatapaan (North region), Sub District of West Amurang (Central region) and Sub District of Sinonsayang (Southern region). The data used in this research includes primary data and secondary data. Sources of data collected are primary data from farmers and secondary data from relevant agencies that are related to this research. Economic valuation methods use primary data obtained from direct observation in the field, with the method of in-depth interviews with respondents based on the questionnaire that has been prepared in accordance with the objective of the study (Hidayatullah, et al., 2011). Determination of sample villages and sample farmers was carried out by purposive sampling. The sample villages were selected by the criteria of the village which had a large cattle population, while the sample farmers with the criteria of having cattle and coconut plantations. This study analyzed the potential for developing cattle based on livestock density using the analytical method used by Ashari et al., (1995), where livestock density is divided into three types, namely (i) economic density; (ii) farming density; and (iii) regional density, based on other statistical and secondary data, the formula can be seen in Table 1. Table 1. Formulas and Criteria for Cattle Density *) AU= animal unit.

III. RESULTS
The environment and climate in South Minahasa supports the development of tropical agriculture. In general, commodity crops and plantations cultivated in this area are food crops (rice, corn, potatoes, cassava, sweet potatoes, peanuts and soybeans), horticultural plants (carrots, beans, spices and onion stems), fruit plants (banana, pineapple, orange, avocado, papaya, mango, durian and rambutan), and plantation crops (coconut, cloves, and vanilla). South Minahasa Regency has the highest planting area of coconut which reaches 45,041 ha, with total production per hectare of 49,375 tons. Corn is a food crop that has the largest harvest area among other types of food crops, which is as much as 20,882 ha with a total production of 3.94 tons per hectare. Coconut plants have the largest planting area in South Minahasa Regency, because this regency is one of the centers of coconut production in North Sulawesi province. Coconut plant area has great potential for cattle development, because the area can be planted with grass and legumes for forage under coconut trees. Productivity of Pennisetum purpureum cv. Mott in coconut field that has been fertilized with cattle manure based compost, produces the yield of fresh forage per year can reach 661,947.64 kg per hectare per year, then the stocking rate per hectare of land under coconut trees can be given to around 45.34 heads of cattle a year  The development of cattle in the research area can be done by taking into account the existing values and density criteria of livestock. Determination of values and criteria is based on potential economic density, farming density, and regional density in a region. The results of the study on the value and density criteria of cattle in South Minahasa Kabupaen the res ults of the analysis can be seen in Table 2. Table 2

. Values and Levels of Cattle Density in South Minahasa Regency
The economic density of the sample sub-districts in South Minahasa Regency is in the rarely and medium level categories, farming densities generally include level rarely, and regional density including still rarely and medium density. This shows that economic density for cattle is still rarely and medium density compared to the population. If seen from the density of farming, which is generally still rarely density, so it still has a great opportunity to continue to be developed, whereas it is

IV.
CONCLUSION The combination of economic, farming and regional densities is known that the sub-districts that receive the first priority in the development of beef cattle are Sinonsayang and Amurang Barat sub-districts including the southern part of South Minahasa Regency, because this region can develop good cattle farming and forage grass and legumes in coconut fields which are mostly located in this region through a system of integration of coconuts and beef cattle (coco-beef integration system). Whereas in Tatapaan Subdistrict and other sub-districts in the North and East regions of South Minahasa Regency it is not a priority for cattle development, because this region is more dominant with clove plantations and food crops such as paddy fields and other food crops .
