Abstract

ABSTRACT            Utilization of the area by human needs has resulted in a narrowing of the habitat of long-tailed monkeys and monkeys which has triggered human and wildlife conflicts such as in Petai Village and Pulau Padang Village which are around the Bukit Rimbang Bukit Baling Wildlife Reserve. This conflict between humans and wildlife has a negative impact, both in the form of a decrease in the population of long-tailed monkeys and monkeys in their natural habitat as well as in the form of economic losses for the community. Such conditions require the calculation of the economic value due to human and wildlife conflicts as part of the consideration in obtaining efforts to resolve the conflict. This study aims to determine the prevention efforts of long-tailed monkey andmonkey conflicts with humans and to determine the value of losses due to disturbance of long-tailed monkeys and monkeys in Petai Village and Pulau Padang Village. This study uses purposive sampling method, using the Slovin formula as many as 74 respondents. Methods of data analysis using descriptive analysis to determine conflict mitigation techniques for long-tailed and monkey monkeys and quantitative analysis to be used to calculate the value of human losses and conflicts with long-tailed and monkey monkeys, namely the value of agricultural damage losses in rupiah units. Damage to agricultural commodities in Petai Village and Padang Island, namely oil palm, rubber, banana, papaya, chilli, eggplant, long beans and cassava. The results of the calculation of the average damage in Petai Village / one attack obtained a value of Rp. 1,786,413 per household, while in Pulau Padang village the average calculation of damage / attack was Rp. 2,645,009 per household. Efforts to control conflict by the community are in the form of guarding and controlling the gardens, making barriers in the form of installing wire fences and evictions.Keywords :Conflict, Long Tailed Monkey, monkey, Mitigation, Damage Costs, wildlife.

Abstract

Aren (Arenga pinnata Merr) is a type of palm plant that produces fruit, sap and starch or flour in the stems. Peat from its natural formation process has a low fertility rate because it contains high organic acids. Rice husk ash is the result of burning rice husk which can improve soil properties, so that it can support more optimal plant growth and development. The purpose of this research was to determine the effect of the application and the best composition of rice husk ash on the growth of palm seedlings on peat medium. This study used a non-factorial completely randomized design (CRD), which consisted of one factor, namely the dose of rice husk ash with 5 treatment levels and 4 replications in order to obtain 20 experimental units. The treatment of rice husk ash (T) consists of 5 levels with the following dosages: T0 = without application of rice husk ash (control) 100% peat, T1 = application of rice husk ash 10% polybag + 90% peat, T2 = application of rice husk ash 20 % polybag + 80% peat, T3 = application of rice husk ash 30% polybag + 70% peat, T4 = application of rice husk ash 40% polybag + 60% peat. The application of rice husk ash affects the dry weight of palm (Arenga pinnata Merr) on peat medium. The best application of rice husk ash at a dose of 40% rice husk ash plus 60% peat can increase the growth of increase in diameter 0.29 mm, plant dry weight of 1.92 g, crown ratio root 2.25. Keywords : Arenga pinnata, rice busk, growth.
