Abstract

ABSTRAKTujuan penelitian ini adalah untuk menentukan mutu fisik yang meliputi keadaan bau, warna dan rasa serta mutu kimia yang meliputi komposisi asam-asam lemak, kadar air, FFA dan bilangan peroksida virgin coconut cooking oil (VCCO) hasil pemanfaatan limbah VCO (ampas kelapa) dari varietas kelapa Dalam Mapanget, kelapa Dalam Tenga, kelapa Hibrida KB-3 dan kelapa Kenari. Penelitian ini diharapkan dapat memberikan informasi tentang mutu fisik dan kimia VCCO serta dapat memberikan nilai tambah bagi limbah ampas kelapa sebelum dijadikan pakan ternak atau dibuang. Penelitian ini menggunakan metode deskriptif mutu fisik dan kimia VCCO dari keempat varietas kelapa diatas terhadap SNI 01-3741-2002 tentang standar mutu minyak goreng. Hasil penelitian menunjukan bahwa mutu fisik meliputi warna, bau dan rasa dari VCCO yang dihasilkan dari beberapa varietas kelapa (ampas kelapa) memenuhi SNI 01-3741-2002 tentang minyak goreng yaitu normal untuk bau dan rasa serta berwarna putih hingga kuning pucat. Mutu kimia VCCO dari keempat varietas kelapa (ampas kelapa) memiliki komposisi asam lemak yang didominasi asam laurat antara 42.16% – 47.39%, kadar air antara 0.19% – 0.27%, asam lemak bebas (FFA) antara 0.19%– 0.30% dan Bilangan Peroksida 0.20 mg ek/kg – 1.80 mg ek/kg. Dengan demikian memenuhi standar mutu yang disyaratkan dalam SNI 01.3741-2002 tentang minyak goreng sehingga dapat dinyatakan baik dan layak diterima.Kata Kunci : kelapa, minyak kelapa, limbah VCO (ampas kelapa)

ABSTRACTThe objective of this research is to analyze the industry prospect of processing fried banana in Manado City by taking samples in the research region : Klabat Stadium and Malalayang Beach. Forty respondents were interviewed as representatives to the amount of consumer in Manado.This research was carried out at Klabat Stadium and Malalayang Beach from each location, two sellers were taken as samples start from September to October 2012. This research used primary and secondary data. Primary data were through directly interviewed with the owner and the employees of the sampel location and the forty respondents as the population of fried banana lovers. Secondary data taken through the literatures and institutions related with this reacerch. Analyzes data was showed in tables form.This research result showed that industry of processing fried banana in Manado City has a good prospect because it gained profit. Revenue Cost Ratio that obtained from each location is bigger than others. In condition like this business of fried banana deserves is feasible. Besides the profit sellers would obtain the opportunity doing this business is high because there are many consumers of this product in Manado City.

Abstract

ABSTRACTThe main problem in the post-harvest handling of paddy that often facing by the farmers is the high value of looses during post harvest. The looses occur when the paddy grains scattered during harvest or post harvest handling. This study aimed to calculate the losses of paddy grains during drying and milling in Minahasa Region. The research was conducted in Karondoran village, the east part of Langowan, Tolok village of Tompaso and in the Post Harvest Laboratory, Faculty of Agriculture, Sam Ratulangi University for 3 months. The drying looses was determined by the weight and the moisture content of the paddy samples before and after the drying process. While the looses during milling was determined by comparing the rendemen of millling and the milling yield generated in the laboratory. The result indicated that the average looses of drying in Minahasa was 2,19% while the average looses of milling in Minahasa was 2,12%.Keywords : drying, milling, looses

ABSTRACTCork fish balls (Ophiocephalus striatus) is one of the products processed from fish meat shaped cork sphere obtained from fish meat mixed formulations of existing cork and starch in tapioca flour and adding pureed carrots. This study aims to get the fish balls in physicochemical and sensory panelists preferred the addition of pureed carrots treated as a source of natural dyes in fish balls cork. Organoleptic test results, treatment was continued with an analysis of selected physical properties and chemical analysis. Organoleptic test results for fish balls cork that is treated E (10g carrot porridge: 5g tapioca flour) is the most preferred treatment by the panelists. The results for the test fish balls cork texture for fish balls cork on the chosen treatment is the treatment formula E = (10g carrot porridge: tapioca flour 5g) was 1.69 mm / gr / sec. With the analysis of the chemical properties of the water content of 77.36%, ash content 1.54%, 13.38% protein, 1.19% fat, 0.57% crude fiber, total carbohydrate 5.96%, and the content of vitamin A <0.5 IU.Keywords : Cork fish ball, pureed carrots, tapioca flour

Abstract

AbstractThe objective this study was to predict erosion rate and erosion hazard level in DumogaSub-watershed. The study is expected to provide spatial information on erosion rateand erosion hazard level in Dumoga Sub-watershed, particularly for spatial planning as wellas soil and water conservation. Erosion was predicted employing USLE while spatial analysiswas conducted using Geographic Information Systems (ArcView 3.3). Rainfall data were collectedfrom three weather stations, erodibility values obtained by analyzing samples fromthree soil types, slope categories were determined using DEM (Digital Elevation Model), valuesof the landuse and soil conservation were determined by means of satellite image interpretationin and field survey as well. It was found that soil erosion ranged from 0.39 to16.800 tonnes /ha/year. The lowest erosion rate occurred on forest land and ricefield withhacingflatslope. The highest erosion rate was identified on farm land having very steep slope.Erosion hazard level varied from verylow to very severe. It is necessary to perform soil andwater conservation measured on the land experiencing severe to very severe erosion hazardas to reduce soil erosion.Keywords: Erosion, Geographic Information System, Watersheed

Abstract

ABSTRACT The purpose of this study was to determine the effect of compost on land mined gold and knowing which one is the best type of compost to the early growth of the plant jackfruit. This research used Completely Randomized Design (CRD) factorial with 2 faktoral namely Factor A: types of compost with three levels while the B factors and three levels of fertilization and repeated 3 times so have 27 pot experiment. The results composting on mined land can improve soil chemical properties in this case the addition of the nutrients N, P, K and C-organic. Nutrient content of compost can be seen that the highest N content contained in compostable materials made of peanuts is 0.8%. While the highest available P in compost bins gamal is 16.79 ppm, the highest available K in compost market is 55.3 ppm and C-gamal organic compost is the highest at 9.11%. Jackfruit plant growth height and number of leaves both the best in the mined soil compost bins given market.
