Abstract

The objectives of this research were to analyses the rice farming income and the rice marketing system in Karawang district. Primary data were collected in this research involved  34 paddy farmers in Karawang and 12 rice traders and secondary data that is relevant to the research were collected.  The analysis of rice farming was conducted for the first growing season of 2011. Most of rice farmers are the selfowner with an area of ​​between 1 to 5 acres. The selling price of unhusked rice crop received by farmers ranged between Rp 2.200,00 to Rp 3.800,00 with an average of Rp 2.720,54. Value of R / C ratio is 1.50 based on total cost. The actors in rice marketing are paddy farmers, local rice mill, sub-district’s and Cipinang’s market wholesaler and retailer.   The biggest margin obtained by the local rice mill.  The biggest farmer’s share found at the market flows from farmer à sub-district wholesaler à Karawang retailer.  The biggest benefit cost ratio of marketing found at market flow from farmers à local rice mill à Cipinang wholesaler à Jabodetabek’s retailer.  The market structure at farmer level is nearly perfect, however at the other level (rice mill, wholesaler and retailer) the market structure is oligopoly and oligopsony.  The selling price of grain has a significant impact on farmers income, so the role of the Government is expected to overcome this, such as by optimizing the role of the “Lumbung Desa Modern” (LDM), which is the existence still not optimal yet.

Abstract

The objectives of the research are (1) to analyze the income of sweetpotatoes farming in Cikarawang Village, (2) to analyze factors that influence the sweetpotatoes production, and (3) to analyze the technical efficiency sweetpotatoes farming. Research are carried out during March-April of 2012 in Cikarawang Village, Bogor District, West Java. The primary dataareobtained through interview with 35 sweetpotatoes farmers. To analyze the data, the stochastic frontier production function approach and farming income analysis are applied. The result shows that, first,the income of farmers with land more than 0,5 hectare are Rp 12.344.377 per hectare per season. However, farmersthat own less than 0,5 hectare only obtained Rp 1.909.161 per hectare per season. Second, the R/C quotient of sweetpotatoes production that reach >1shows that the sweetpotatoes production are profitable. Third, factors that influence the sweetpotatoes production are land size, labor, fertilizer, and pesticide. Fourth, the average technical efficiency that reach 0.564 shows thatthe sweetpotatoes farming onlyreach 56.4 percent of the maximum productivity. The research reveals that low technical efficiency of the sweetpotatoes farming are related with experience and age of the farmer. To increase the sweetpotatoes production, government should strongly promote and disseminate the production innovation and post harvest technology.

Abstract

The objectives of this paper are (1) to analyze the relationship of “dust grade” tea price at Jakarta, Colombo and Guwahati Tea Auction Markets, and (2) to perform Vector Autoregression (VAR) models in order to forecast the “dust grade” tea price at Jakarta Tea Auction Market. Grade dust tea is used to make the tea bag. The average weekly price of dust grade tea from the third week of February 2009 until the second week of April 2011 was used in this analysis. The results showed that firstly, there was no significant price transmission from Colombo and Guwahati Tea Auction Markets to Jakarta Tea Auction Market. There was no significant co-integration among the three markets. As a matter of fact, the price of dust grade tea at Jakarta Tea Auction Market was affected by its price of one week earlier at its own market. Secondly, Naïve model was more accurate compared to VAR model in order to forecast the price of dust grade tea at Jakarta Tea Auction Market. Further research is needed in order to perform the more accurate forecasting model to predict the price of dust grade tea at Jakarta Tea Auction Market.

Abstract

The purpose of this paper is to assess whether the national program on beef self sufficiency could be achieved at 2014. A dynamic system model with Vensim computer program is applied. The model validated by Mean Absolute Percentage Error. The results shows high accuracies of the model. The assessment show that, first, the beef self sufficiency would not be achieved at 2014 if the program are treated and running as usual (Scenario I). Second, the beef self sufficiency would be achieved at 2015 if government increase the cow population by reducing the slaughter of local cows and expanding the cross breeding program through artificial insemination (Scenario II). Third, the beef self sufficiency would not be achieved at 2014 if the actual beef consumption are higher than the supply that produce through Scenario II (Scenario III). Another innovative solution for increasing local cow population is needed.

Abstract

The purpose of this research is to design and implementation Maximum Solar Power Tracking system using photovoltaic panel, in order to increase solar panel efficiency and power. Data collection is done for the condition in Semarang city. The result of the research is expected to be base in planning of solar power system in Semarang city, whether it is for lighting lamp planning and for Solar Home System (SHS). This MPPT system design uses standard 180 degree servo motor to drive photovoltaic panel and control circuit using ATmega IC, while simulation using MATLAB program. Tracking is done by online tracking method by moving the photovoltaic panel to the radiation of the sun. Tracking simulation is done with step 20, 50 and 180 step. The average of voltage generated by system without tracking is 3.97 Volt while the average voltage generated by tracking system is 4.72 Volt. Efficiency between system without tracking and tracking system is 66.28% for tracking system and 78.78% for tracking system

Abstract

The spread of earthworm habitat much larger on the banks of the rivers in Central Kalimantan.The aim of this study was to characterize the habitat of earthworm located on banks of the rivers of Kahayan and Barito. Preparation of soil profile with dimension 1x1 m and a depth of 20 cm was conducted using transect procedure and positioned from dried riverbed up to river embankment. The results showed that earthworms with a larger size identified as Lumbriscus terrestris was mainly found in Kahayan river, while for relatively smaller species, it was found at Barito river identified as Lumbriscus rubellus. The number of L .rubellus populations is more 12 and 522 earthworms per layer than L. terrestris. The shallow of water level for ground water and rough texture was not suitable condition for earthworm habitat at both location. The level of protein and ash content are 30.30 % and 42.78 % respectively and higher compared to L. rubellus i.e 13.28 % and 6.27% respectively.

Abstract

Persoalan pangan merupakan persoalan kritis yang saat ini dihadapi oleh semua Negara di dunia. Tidak lepas dari ingatan, bagaimana pada tahun 2013 terjadi keriuhan di pasar Indonesia terkait harga daging, terutama daging sapi. Persoalan tersebut muncul karena terjadinya permintaan daging sapi yang terus meningkat. Sayangnya, peningkatan tersebut tidak diimbangi peningkatan produksi daging sapi dalam negeri. Selisih permintaan pasar dan ketersediaan daging sapi secara nasional menyebabkan pemerintah mengambil kebijakan impor sapi dan daging sapi sebesar 35% dari kebutuhan daging sapi secara nasional. Untuk jangka panjang, pemerintah telah mengambil kebijakan untuk mewujudkan swasembada daging sapi berbasis sumberdaya domestik. Kebijakan ini dilakukan untuk mengurangi ketergantungan terhadap sapi dan daging sapi impor. Tantangan kemudian muncul untuk mengoptimalkan peternak rakyat, yang merupakan bagian paling besar dari sistem peternakan Indonesia.
