Abstract

This study aims to determine the growth response and Plant Production of Broccoli (Brassica oleracea Var. Botrytis) with application of Azolla composting in some plant spacing. This research used a Factorial Randomized Block Design with two factors namely: Azolla Composting Factor (A) with 4 levels 0, 32, 64, 96 and A4 = 128 g/plant. Plant spacing factor with 3 levels 45 cm x 45 cm, 50 cm x 50 cm and 55 cm x 55. The results showed that the application of Azolla compost 128 g/plant had significant effect on the stem height, stem diameter and flower weight. Plant spacing in 55 cm x 55 cm only affected the flower weight. There was no interaction between Azolla compost and plant spacing for all parameter observed.

Abstract

Abstract. The purpose of this research was to analyze the marketing system and marketing channel of chicken eggs and to analyze marketing efficiency based on marketing margin, price share and profit ratio of chicken egg cost in Pematangsiantar Municipality of Simalungun District. This research was conducted for two months, from July to August 2017. The methods used in data collection were: sampling of breeders and other marketing institutions selected by snowballing sampling technique and data collection methods was done by interviewing techniques using questionnaire. Data analysis included: marketing costs, marketing margin,farmer share and profit cost ratio of each marketing channel. The results of this study indicated that there were four marketing channels. The marketing margin on the Channel II showed the smallest cost margin and the largest profit margin so that it showed the largest cost-benefit ratio. The largest farmer share was obtained on the Channel IV but this channel used only the retailers as an intermediate channel (one level) and relatively few exchanged eggs. So it was concluded that the Channel II was the most efficient channel becauseof the smallest cost and that the profits were spread evenly among all the marketing institutions that play a role. The need for chicken eggs in Pematangsiantar Municipality was supplied from outside the city (63.33%) and filled by breeders from within the city(36.66%).

Abstract

The study aims to analyze the economic value of dried fish business by considering its added value of Hayami and marketing. This study uses primary data by surveying 55 dried fish producers in Bengkulu city. The results show that the average output price of dried fish is Rp6,586.61/kg. Using formula of Hayami’s added value, the average added value gained is Rp3,486.14/kg. This informs that every a kilogram of fresh fish processed into dried fish will create added value of Rp3,486.14. When labor under consideration, labor added value in fish dried industries is Rp651.37 informing that an average of labor income for every kilogram of fish dried produced. The research also found that there are four patterns of marketing channels. From weekly average production of dried fish, i.e., 4,345 kg, 43.73 % is distributed to big traders while the remaining, 56.27%, is consumed directly. From big traders, dried fish are then distributed through three channel, namely, (1) 43.11 % are marketed to the first intermediate trader, then, to intercity merchants, retailers and end customers in Bengkulu city, (2) 26.32% are distributed to second intermediate trader who then marketed to retailers and end customers; and (3) 31.58 % are marketed to third intermediate trader who, then, market to the intercity merchants and consumers. Marketing margins of this dried fish is Rp1,000/kg from producers to traders and Rp2,000/kg per kg of fish from traders to retailers.

Abstract

Curcuma aeruginosa is one of the herbs with health benefits and has been used in traditional medicine, has the characteristic bitter taste, so that limited use was. The formation of walls in the active component coating process can minimize direct contact of bitter receptor cells in the oral peripherals so the perception of bitterness can be reduced. This study used a variation of the WPI concentration as the coating wall materials 10%, 15% and 20%. Formation of coating walls was analyzed using SEM later in the sensory test for effectiveness decreased level of bitterness. The addition of 10% WPI results in the best wall formation was in Curcuma aeruginosa, which could decrease perception of significant bitterness. In contrast to the addition of WPI 15% and 20% were found in an oval shape, craters and ruptures form on coating wall, reducing the protection of the core component and contact with bitter receptor cells in the oral peripheral resulting in bitters taste perception increasing.

Abstract

Poultry is an important sub sector of livestock and is ahead of all other sub sectors in economic growth. Broilers production is a specialized branch of poultry farming. This research was conducted in Mansehra is the region where considerable amount of commercial broiler production takes place. The region of the study has a high concentration of commercial activities, infrastructural facilities like veterinary care as well as climate that favor the production and marketing of poultry meat products. This research was conducted in nine villages of district Mansehra namely Kotli Pain, KotliBala, Kheil, Tanda, Bafa, Chatar Plain, Ahl, Batal and Mongandawraha. The purpose of the research was to analyze the competitive advantage of broiler farming. There were 276 broiler farms in District Mansehra. Simple Random Sampling Technique was used for data collection from 70 respondents. Average total cost of production was found Rs. 738238.11 having average farm size of 3605 broilers. Feed and one day old chick costs constitute 90.01% of the total cost. Average expenditure on production per broiler was Rs. 220.20 having net profit per broiler of Rs. 24.11.Based on Porter study (1990), average variable cost (C) was used as a proxy for competitive advantage. Results of regression analysis show that the main factors that significantly affect competitive advantage of broiler farming in the study area was feed cost, day old chick cost, labor and medication cost while capacity utilization and extension service contacts negatively and significantly affect cost. It means that reducing the above mentioned costs and using installed capacity and extension service contacts will reduce production cost and will promote competitive advantage of broiler production. Broiler production should be encouraged through better feed management practices and also by feeding broilers with nutritious feed. Broiler farmers should be encouraged to fully use their installed capacity of their farm.

Abstract

The development of the implementation of non-tariff measure policy, in the world market which has a trend, increased every year. There are seven (7) NTM policies mostly implemented in the international market. The most policy application is the implementation of Technical Barriers to Trade and Sanitary and Phytosanitary. Agricultural commodities both vegetables and live animal products are commodities mostly become subject to NTM policy in the form of SPS (Sanitary and Phytosanitary) and TBT (Technical Barriers on Trade) in the international market. Indonesia as an agricultural country that has advantages in agriculture and fisheries cannot avoid the implementation of SPS and TBT policies. This research was aimed to analyze the effect of SPS and TBT on Indonesia’s shrimp export using the gravity model. The results showed that the GDP of exporters and the exchange rate have negative influences on Indonesia’s shrimp exports. Meanwhile, the GDP of the importers and trade cost have positive influences on the export of shrimp Indonesia. while the SPS policy and TBT don’t affect Indonesia's exports of shrimp in the international market. This indicates that Indonesian shrimp exporters are able to quickly adjust the SPS and TBT policies applied by importing countries.

Abstract

One of the organisms that helps in decomposition of oil palm empty fruit bunches is Oryctes rhinoceros L. larvae. This is because of in the gut of the larvae there are many cellulolytic bacteria and lignoliytic. The process of accelerating the decomposition of oil palm empty fruit bunches into compost can be done by optimizing the work of the bacteria. The aim of this research is to obtain cellulolytic and lignolytic bacteria from larvae O. rhinoceros L.. The research succeeded to isolate 24 isolates of cellulolytic bacteria and lignolytic bacterial isolates from the gut of O. rhinoceros larvae. Based on qualitative test, 9 isolate bacteria produced cellulolytic index above 2. The highest cellulolytic index was generated by ORL19 isolate, while the lignolytic index obtained ORL6 isolate. Based on macroscopic and microscopic identification of bacteria, biochemical and physiological tests, it was found ORL 6 belongs to the genus Bacillus sp. while the ORL 19 belongs to the genus Citrobacter sp..
