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

Mung beans are legumes that known and cultivated in Indonesia. This plant is an important commodity. Utilization of oil palm processing plant sludge is still not optimal, therefore sludge can be utilized as an alternative supply of nutrients for the development of green bean plants. PKS sludge is the waste from the byproduct of the processing of fresh fruit bunches (FFB) in the form of solid objects that sink at the bottom of the sedimentation plant of a palm oil mill into crude palm oil or Crude Palm Oil (CPO). The study was conducted at the Technical Implementation Unit (UPT) Experimental Garden of the Faculty of Agriculture, University of Riau from August to October 2018. The research was an experiment in the pattern of a 4x3 factorial using a split plot design. As the main plot, PKS sludge solid waste consists of 4 levels (0, 8, 16, and 24 tons.ha-1), as subplots namely three varieties of green bean plants consist (varieties Vima-1, Kutilang and Vima-3) , each repeated 3 times. The results showed there were variations among varieties of green beans, which were observed in which Vima-1 variety gave better results for the age of emergence of flowers, age of harvest, and weight of 100 seeds. Varieties of Kutilang on the parameters of percentage of pith pods and Vima-3 varieties on parameters of plant height, number of branches, number of seeds per pod and weight of seeds per plot. Of the three varieties tested, Vima-3 produced the highest plant height of 65.12 cm and yieldof 493.74 gr.m-2. Keywords: Green beans, varieties, sludge

Abstract

Aquilaria malaccensis is one of the plants used for peatland restoration activities. Provision of quality A.malaccensis seeds is needed in conservation activities. To get a good quality of A.malaccensis must use proper cultivation techniques. Mycorrhizae and Trichoderma spp. can improve seedling growth and suppresses pathogenic. Application of mycorrhizae and Trichoderma spp. are on of the success techniques of cultivation, but need to know the potential time to apply. For this reason, this research was conducted to determine the potential time application of mycorrhizal and Trichoderma spp. to increase seddling growth. This research used a completely randomized design (CRD), which consist of 5 treatmens, 10 replications and each replication consisted of 1 seedling. The treatments used were : T1 = Trichoderma spp. on S-5 and mycorrhiza on S-1, T2 = Trichoderma spp. on S-3 and mycorrhiza on S-1, T3 = Trichoderma spp. and mycorrhiza on S-1 , T4 = Trichoderma spp. on S-1 and mycorrhiza on S-3, T5 = Trichoderma spp. on S-1 and mycorrhiza  on S-5, where S = seedlings were transferred to polybags after treatment. The parameters measured were seedling survival percent, seedling height increase, seedling diameter increase, plant dry weight, and root canopy ratio. The results of this research that the application of Trichoderma spp. in 5 days before the seedling were transferred to polybags and mycorrhizae 1 day before the seedlings were transferred to polybags showed the best result for the growth of A.malaccensis seedlings with seedling height increase is 5,13 cm, plant dry weight is 1,14 g and top-root ratio is 3,09. Keywords : Aquilaria malaccensis, mycorrhizae, Trichoderma spp., peat medium
