ABSTRACTJelita Lapadjawa, 100314045, Role of the Agricultural Sector of the Economy East Bolaang Mongondow Regency under the guidance of Olfie L.S Benu as chairman, Grace A. J Rumagit and Welson M. Wangke as members. This study aims to determine (1) the role of the agricultural sector in the East Bolaang Mongondow Regency Economy, (2) the development of the agricultural sector within 5 years, from 2008 to 2012, and (3) whether the agricultural sector is a base or non base sector. The research was conducted in the East Bolaang Mongondow Regency. The data used was secondary data, collected from Statistics Indonesia (BPS) both at Kotamobagu City Office and North Sulawesi Province Office. The data was then analyzed using the contribution formula, the growth formula, and Location Quotient (LQ).The results showed that the agricultural sector was not the biggest contributor to the regional economy of the East Bolaang Mongondow Regency. The results of the study alsonoted that the development of the agricultural sector to the GRDP showed an increase from the year 2008- 2012, with the largest increase occurred in 2010 with the growth rate of 6%, and in 2012 it reached 4.66%. This could mean that the agricultural sector in the East Bolaang Mongondow already had good productivity. From the LQ analysis, it was shown that Agriculture was a base sector in the East Bolaang Mongondow, meaning that the role of agriculture in the East Bolaang Mongondow was larger compared its role in the province of North Sulawesi. Moreover, within Agriculture sector, it was shown that forestry, plantations and farms were the leading subsectors.

ABSTRACTThis research was conducted to test the relation between salinity and distribution pattern of mangrove vegetation in Teling, district of Tombariri. This research aimed to describe the distribution of main zones of mangrove plant species in relation to the salinity of sea water in Teling, district of Tombariri. This research was conducted from July to August 2014 at the mangrove forest at Teling, the district of Tombariri, North Sulawesi. This research used the combination of plot and line method. There is mangrove zonation in Teling District of Tombariri which consists of (from the sea to the mainland) Sonneratia zone (zone 1), Rhizophora zone (zone 2), and Bruguiera zone (zone 3). Zone 1 is located in the outer portion or directly adjacent to the sea. Zone 2 is between Sonneratia zone and the adjecent land. Zone 3 is located at the rear of Rhizophora zone and only found on one track at the research site. The average salinity values on Sonneratia zone range from 33 ‰ to 35,5 ‰, whereas the range for Rhizophora is from zone 31,8 ‰ to 33,7‰ and Bruguiera zone is 33‰.Keywords: Mangrove, Bunaken National Park, Zoning, Salinity

Abstract

ABSTRACTSoil tillage aims to create physical soil condition suitable for plant growth. It does that by improving soil water and air association as well as water movement in soil. Mechanical soil tillage requires lots of energy; therefore, good tillage practice needs to carefully consider a proper soil condition in order to get the required result. A technical test to Kubota tractor type M9540 with 95 horsepower was done in this research, as it has never been done before in specific soil condition, topography, and climate of the North Sulawesi. The objectives of this research were to measure aspects of effective field capacity and field efficiency, fuel consumption, to calculate tillage cost and tractor Break Even Point. Soil tillage results were also evaluated by measuring soil bulk density, water infiltration and moisture content before and after tillage. The test was done by cultivating the dry land through performing primary and secondary tillage, each was carried out in three replications. The results show that average effective field capacity for first primary tillage was 1.55 m2/second (0.56 ha/hour), second primary tillage was 1.75 m2/second (0.63 ha/hour), and the secondary tillage was 2.72 m2/second (0.98 ha/hour) with average field efficiency was 77.40%, 80.72%, and 56.17% respectively.Total time to complete the first and second primary tillage was 0.11 hour and 0.10 hour, with diesel fuel consumption of 64.17 liters/ha, and 55.44 liters/ha. The secondary tillage required 0.06 hour and fuel consumption of 28.72 liters/ha.The primary and secondary tillage were found to influence the soil moisture content, bulk density, and rate of water infiltration. Tillage basic cost is calculated as Rp.1.765.683 /ha to result a hire charge of Rp. 1.942.251 /ha, and the tractor break-even point was found to be 552 ha/year.Keywords: Tractor, tillage

Abstract

ABSTRACTNutmeg syrup is one way to diversify products of nutmeg. IKM “Sari Fruit” is one of nutmeg syrup producers in North Sulawesi, especially in the District Sitaro. However, nutmeg syrup in the market has not specified expiration date. One method that can be used to determining the shelf life of food product is ASLT (Accelerated Shelf Life Testing). This research aims to determine the shelf life of nutmeg syrup production IKM "Sari Fruit" Sitaro using ASLT (Accelerated Shelf Life Testing) with the Arrhenius approach. The benefit of this research is to give information and advice to the industry of nutmeg syrup to determine the shelf life of the product before it is marketed. In this research, nutmeg syrup stored at 30 ° C, 35 ° C and 40 ° C for 4 weeks. The parameters used to analyze the decline in the quality of nutmeg syrup are pH, sugar content, viscosity, total yeast and organoleptic tests. The results showed that the shelf life calculations are based on the pH because it has the smallest activation energy, ie 4,025.66 cal / mol. Shelf life of nutmeg syrup at room temperature storage (27 ° C) was 13.6 weeks.Keywords : Nutmeg syrup, shelf life, ASLT, Arrhenius
