Abstract

The objective of this study was to identify factors involving in production, marketing, margin of marketing and efficiency of marketing in Labuan Toposo, district of Tavaeli, Regency of Donggala. Samples were purposively chosen from a corn prroducer area. The total number of samples used were 39 people, consisted of 30 farmers, 4 collecting seller, and 5 retailing seller. Primary and secondary data were collected by direct interview with the farmers. The results indicated that all variables were significance at α 1% on corn production with F-test (156.37) > F-table (4.18). Partially, farm area size (X1) was highly significance with t-test (2.88)>t-table (2.78). Others variables shown significance were seed (X2) with t-test (2.36) > t-table (2.06) and manure (X4) with t-test (2.41)>t-table (2.06). The only variable shown not significance was employer (X3) with t-test (1.74)>t-table (2.06). Marketing analysis showed that type one marketting channel which has margin of IDR 250 was as followed farmer, collecting seller, and consumer, respectively.  It is more efficient than type two channel: farmer, collecting seller, retail seller, and consumer, respectively, having margin of IDR 750.

Abstract

Solar thermal energy is one of the potential energy to be explored and developed further as a source of backup energy. To be able to directly utilize solar thermal energy to heat water can be used in a device that can collectsolar energy to the Earths surface and convert it back into useful heat energy. This device is called the solarcollector. Solar collectors can be defined as a heat transfer system that generates thermal energy by harnessingthe Suns radiation as the main source of energy. After testing by varying the flow capacity of 3 litters /minute upto 10 liters/minute, then in the temperature of the fluid can come out (Tout) is the highest of 61,9 C, which ispresent on the stream discharge 7,5 litters/minute. And the highest efficiency in the discharge flow of 5 litters/minute is equal to 86,54%. The results of this test indicate the efficiency of the collector surya.

Abstract

Rooftop solar copra dryer tool is an instrument used for drying copra with capacity ± 40 kg, for one drying. The purpose of this research is to see how to efficiency drying in a series connectivity on copra process of drying. Using the dryer solar can exsiccate drain agricultural products. Where the work plase, sunlight absorbed or strored through solar collectors, heat will come from the collector come into a system of air flow to the piping system and forward to the drying. Design tool dryer aims to exsiccate copra of the water is decreased from 52.68 % until 5-6 %. Medium dryer is the heat produced by the capture of the sun and distributed for ciblyin to the drying chamber they would be used for drying copra. After doing research with the experimental method to directly observe and measure the way things are done in the dryer and then do the processing and evaluation of test data. From the results of tests and calculations, drying wits series to get a final moisture content of the materiall is achieved after 25 hours of drying by using a tool maker Rooftop wits 5.97 %. Final moisture content of the materiall is achieved after 25 hours of drying with direct drying wits 24%. Rooftop solar copra dryer appliance is more Effective and Efficient. Un contaminated by air environment (dust, sand, vermin and its other)

Abstract

Heat Exchanger is a device that is used to transfer heat from one medium to another. At Environment ITP there are many kinds of dryers, but they are still depend on the intensity of sunlight. The Heat exchanger is an alternative to the drying process in rainy season. Base on the direction of fluid flow, heat exchanger is includes a heat exchanger types of cross flow. Then the air entering the dryer chamber does not mix with the smoke produced by burning sawdust on the furnace fuel. Air enters through the input with the of a blower and continue towards the composition of the pipe as a heat transfer, hot air continues to flow towards the output. In this tool comes two heat transfer process of heat transfer is natural convection and forced convection heat transfer. To determine the effectiveness of this tool, is influenced by several variables such as : speed, burnbing time, the mass of sawdust, pipe surface temperature, the temperature of the cold air and out, the temperature of hot air inside and outside.

Abstract

Seiring dengan perkembangan peradaban manusia, tingkat kebutuhan energi juga semakin meningkat dan mengakibatkan menipisnya bahan bakar fosil sebagai sumber energi utama. Oleh karena itu diperlukan energi alternative yang terbarukan. Sungai Batang Kularian Kinali Pasaman Barat mempunyai potensi daya yang dapat dimanfaatkan sebagai sumber energy yang terbarukan. Pembangkit listrik tenaga mikro hidro (PLTMH) merupakan salah satu bentuk energi alternatif yang mengolah energi potensial air berubah menjadi energi listrik yang berguna untuk kebutuhan hidup masyarakat. Perencanaan PLTMH dimulai dari survey lokasi perencanaan di Sungai Kularian Kinali Pasaman Barat. Survey dilakukan untuk mendapatkan data perancangan berupa head dan debit air. Data tersebut dapat digunakan untuk menentukan besarnya potensi energi pada lokasi perencanaan PLMTH. Pada perencanaan PLTMH di Sungai Kularian Kinali Pasaman Barat diperoleh data debit air seluruhnya 0,4 m3 /s dan potensi energi listrik sebesar 25 kW. Perencanaan pipa penstock menggunakan pipa berdiameter 500 mm.

Abstract

Abstrak. Penyebaran globalisasi tentu berbeda dari segi intensitas dan cakupannya. Proses tersebut telah menyentuh hampir seluruh sendi kehidupan melainkan juga telah memasuki ketataran systems, processes, actors, dan events. biaya sosial dan politik yang terjadi akibat terbukanya pasar barang dan pasar finansial menjadi tantangan bagi negara-negara berkembang. Liberalisme sangat memperlemah posisi pekerja dan serikat pekerja. Di lain pihak, tenaga kerja tidak terampil (unskilled labor) tidak bebas berpindah ke negara-negara yang tingkat upah rata-ratanya lebih tinggi. Dapat disimpulkan bahwa liberalisasi yang terjadi lebih bersifat kearah yang merugikan kepentingan negara-negara berkembang. Abstract. The spread of globalization is absolutely different in terms of the intensity and the scope. The process has affected not only the all aspects of life but also the sphere systems, processes, actors, and other great events. In addition, the social and political costs of the open society for goods and financial markets are the other challenge for the developing countries. The liberalization weakens increasingly the position of workers and the trade unions. On the other hand, unskilled labours are not free to move to countries that the average wage level is higher. To short, liberalization is detrimental to the interests of developing countries.
