Abstract

Abstract Land cover type is a factor that needs to be taken into account in an effort to rehabilitate a watershed as it can affect planting activities, resulting in varying use of working time.  Nevertheless, technical instructions applied to reforestation are still general. Therefore there is a need for a standard working time in reforestation (planting) as a guideline in determining policies in planting activities. This research was conducted in Bantik Village, Bolaang Timur District, Bolaang Mongondow Regency during one month. to analyze the work performance of planting on several types of land cover. The study used repetitive timing for data collection method which is then analyzed and furtherly tested with ANOVA. The results showed that land cover has a significant effect on work performance, the work performance of planting on young shrub land cover has the highest achievement of 16 seeds per hour followed by an old shrub of 15 seeds per hour and bush of 12 seeds per hour. Keywords: Work performance, plantation, land cover

Abstract

ABSTRACT   Macaca nigra is one of the macaca species on the island of Sulawesi. There are 8 types of macaca on the island of Sulawesi, namely M. nigra, M. hecki, M. nigrescens, M. maura, M. ocrheata, M. tongkeana, M. brunescens, M. togeaus (Nowak, 1999). The study was carried out in the buffer zone of Bogani Nani Wartabone Natural Landscape, South Bolaang Mongondow, North Sulawesi with the aim of finding out the distribution of M. nigra in Pinolosian sub-district, sub-districts of Central Pinolosian and Bolaang Uki sub-district by using a camera trap. 37 camera traps were installed scattered in the Pinolosian sub-district, sub-district Central Pinolosian and Bolaang Uki sub-district for three months. What is observed is how much M. nigra passes through the camera trap.   The result showed that highest level encounter M. nigra found in sub-district Central Pinolosian while in  Bolaang Uki sub-districtwas foundM. nigra. The level of encounter in forest land cover types and APL has no difference. The level of encounter in the closest area of Bogani Nani Wartabone National Park has a high level of encounter on the middle distance. Keywords: Macaca nigra, Camera Trap, Encounter Rate, Roaming Area.

ABSTRACT The Worat-Worat Village community still uses plants in their daily lives as medicines, household appliances, wicker, clothing, food, shelter, and traditional ceremonies. Traditional ceremonies in Woratworat village which are still used today are: traditional eating ceremonies (Orom Sasadu) and traditional wedding ceremonies. This study aims to determine the types and benefits of plants and animals at a traditional ceremony in Worat-worat Village, Sahu District, West Halmahera Regency. The method used in the study was interviews and field observations. The technique of selecting informants using purposive sampling technique. Informants were chosen with certain considerations, in this case the informants chosen to be interviewed were traditional leaders, village leaders and the community. The results showed that plants and animals used in traditional ceremonies included 18 types of plants, namely: rice, sugar palm, betel, areca nut, banana forest, gofasa, sago, cempaka, yellow bamboo, bamboo stone, talang bamboo, balsam tree, durian, melinjo , rattan, kayu besi, coconut and langsat and 4 types of animals namely: wild boar, deer, gosong kelam, and rice snail. The use of plant and animal species in traditional ceremonies is very diverse. The use of these plants starts from the stem, bark, leaves, fruit, and sap. While the animal parts that are utilized are: rice conch shells are used as lime meal, dusky megapode eggs are used as food, wild boar is used as food and deerskin is used for making tifa.

Abstract

ABSTRAC The purpose of this study was to modify and test the evaporator on the production of plam sugar; comparing the processing time of plam sugar between using traditional and modified evaporators to compare the fuel requirements. The result of this study indicated that the process of plam sugar processing using 3 kg LPG gas fuel still take by a long time which was 3 hours 24 minutes using a modified evaporator and 3 hour 9 minutes using a traditional evaporator. Whereas, the process of processing palm sugar  traditionally using wood fuel  was 1 hour 45 minutes. The fuel consumption rate using modified evaporator with 3 kg LPG gas fuel was 1.06 kg/hour; the fuel consumption rate when processing plam sugar using a traditional evaporator with 3 kg   LPG gas fuel was 1.17 kg/hour; while the fuel consumption rate when processing palm sap traditionally with wood fuel was 25.88 kg/hour. The  efficiency of processing palm sugar using  modified evaporator with 3 kg LPG gas fuel was 46%, the efficiency of processing palm sap using a traditional evaporator with 3 kg LPG gas fuel was 45% and the efficiency of traditional processing of palm sap with wood fuel was 11% . Keywords: processing time, fuel consumption, evaporator efficiency
