Abstract

Sun Bear (Helarctos malayanus) is found in Indonesia such as in Sumatra and Kalimantan. Helarctos malayanus is the smallest bear in the world and listed as vulnerable animal. Baloo is a sun bear that is rescued and raised at Bali Animal Rescue Centre located in Tabanan Bali. Before it will be released to the natural habitat, it is important to understand its behaviour, so it will be survived in their natural habitat. This study aimed to investigate the daily activity of sun bear rais at Bali Animal Rescue Centre. Research has been conducted at Bali Animal Rescue Centre from 2nd – 26th January 2019. Observation o daily activities of sun bear was conducted from 08.00 – 16.00 local time. It has been found that most of daily time was spent on grooming (35%), followed by feeding/eating (27%), moving (26%), and stationary (24%). Baloo has hardly found vocalized or defacate/urinate. Baloo was resting around 11.00 am and active feeding/eating along the day as well as moving. She moved a lot at 08.00 am, as she was provisioned by the carer, less moving in the middle of the day (12.00 am) and before resting at 17.00 pm. The variation of time spent on the daily activities of the sun bear at the rescue center can be used as reference before she will be release to its natural habitat.

Abstract

Estuary ecosystem has an important role in supporting the life of shrimp. High productivity and the availability of natural food in the estuary ecosystem, will indirectly affect the growth of shrimp. Penaeus monodon and Penaeus merguiensis were two species of shrimp that had economic value with high demand. The purpose of this study was to determine the biological aspects of Penaeus monodon and Penaeus merguiensis shrimp at estuary of Tukad Aya, Bali. Data collection was carried out in February-March 2019 using quantitative descriptive research methods. The determination of the research station was done by purposive sampling. The results showed the total number of shrimps were caught 1,756 individuals, which consist of Penaeus monodon 151 individuals, Penaeus merguiensis 224 individuals and 1,325 individuals of other shrimp. The composition of Penaeus monodon (8.6%) was less than Penaeus merguiensis (12.76%). Shrimp length measurements were divided into 9 groups with a range of values of 55.15-189.95 mm in Penaeus monodon and 31.3-140.1 mm in Penaeus merguiensis. The results of the length and the weight regression in both species of shrimp obtained the value of b <3 so that the growth pattern of shrimp was categorized as negative allometric where length growth was faster than weight gain.

Abstract

This research aims to determine the financial feasibility on the farming business of breeding balinese cattle who uses KUPS Credit Scheme. Data was collected through observation and interview. Respondents were all members of the “Satwa Winangun” farmers in Tangkas village, Klungkung Regency. Financial feasibility is determined by evaluating the eligibility criteria such: NPV, Net B/C, IRR, and payback period. The assessment was based on 2 calculation systems, (1) calculation of cash costs in which forage and labor are not calculated as the cost (existing condition), and (2) total cost calculation, in which two components are calculated as cost. Based on the calculation of cash costs, cultivation of Bali cattle by utilizing KUPS credit in this village is financially feasible to be implemented. This was indicated by the NPV value of Rp. 274.103.000, IRR 20.16%, Net B/C 1.55, and investments has been able to return within 3.52 years. The result of sensitivity analysis shows that as far as KUPS interest rate is lower than 18.37% per year, this farming is still financially feasible. Breakeven point can be achieved when the number of cattle parents maintained is 37, or when the price of calves at the age of 6 months is an average of Rp. 1.764.022 per cattle. However, based on the calculation of total cost, this farming system is not financially feasible. This is shown by the negative NPV of Rp. -285.721.000, IRR 2.87%, and Net B/C 0,54. This farming system is not financially feasible despite the 0% / year KUPS rate. The break-even point can be reached when the price of calves at the age of 6 months averages Rp. 4.288.367 per cattle.
