Abstract

The greatest governmental investments to farming were irrigation facilities. Those were important to developed and built Indonesian farming. To preserved the conditions,it needed caring from everyone especially their user. It means that farmer’s participation,and user organizations were the most important thing. The research was conducted in Molek irrigated zone, on Kepanjen, Malang regency.Used three independent variables i.e. irrigation facilities, farmer’s participation, anduser organizational climate, and one dependent variable that was farming goals, thenanalyzed by statistics included validity and reliability test, correlation and linearregression. The result showed that irrigation facilities (X1), farmer’s participation (X), and userorganizational climate (X) had a positive correlation (direct relationship) with thefarming goals (Y), followed equation Y = 0.455 + 0.3322 X31 + 0.2845 X.Keyword: irrigation, farmer’s participation, and  organizational climate

Abstract

The export of orchids increased from about US$ 3 million in 1999 to US$ 4,1 million in 2002. An improvement in any aspects of its culture techniques is important to increase its productivity. One of the techniques need to develop is related to the irrigation system. The research was conducted to develop a sprinkle type irrigation system for Cattelya orchids of 6-7 years old, cultured in Batu, Malang. The system was then designed, constructed and tested.   It was found that, the daily water requirement of this particular orchid was 0.12 L. Based on the water requirement, the irrigation system was designed and constructed. At a design level, the measurements showed that the daily discharges of the sprinkle, lateral pipe and main pipe were 0.49 L, 4.88 L and 24.37 L respectively. The total head loss resulted from the sprinklers, lateral pipe, main pipe, 90 angles and joints was 2.46 x 10-4 m, at a total head of pump of 10.00024631 m. The results of the performance tests on the constructed system showed that the discharge levels were lower than that at the designed level. It was probably due to the pump efficiency which was recorded as low as 29.31%. It was found that at 25 Psi, the water sprayed diameter was 0.8 m, with the respective values of the uniformity coefficient, uniformity distribution, PELQ and AELQ were 88.76%, 57.87%, 10.53% and 8.53%. The total cost needed for the irrigation system was 4,197.22 rupiahs/m2.Key words: design, sprinkler irrigation, orchid

Abstract

Various factors need to consider in running an agriculture system sustainable.  The objective of the study was to determine the most important factor on the farming decision making to run a sustainable agriculture system. Descriptive and inferential analytic methods were chosen as the research methodology. The data collected includes several variables covering economical, ecological, human resources and social aspect. A questionnaire was used as a tool to collect the prime data, and then followed by an evaluation of the multiple regressions in order to know the relationship level amongst economy, ecology, human resource and social variable to farming decision making. The result shows that the relationship amongst the variables may be expressed in a linear mathematical model as follows: Farming Dec. Making = - 0.585 + 1.01 Economy + 1.08 Ecology + 0.969 HR + 1.02 Social. The equation model indicates that the ecological variable is to be the most dominant factor in running a sustainable agriculture. Therefore, such variables must be defined to ensure that the agriculture system is run sustainable.   Key Words: farming decision making, sustainable agriculture

Abstract

Tobacco farming supported 70-80% of yearly farmer’s income. Irrigation system application to tobacco was to reduced worker and  increased the efficiency of water use so could reach the quality and quantity of tobacco. As a new technology, it was expensive so that financial analysis is needed in order to know the feasibility of the technology. There were no influenced from watering method application to tobacco’s productivity, quality index and farmer’s income, but gave an influenced to tobacco’s quality (Sugar/Nicotine ratio). The financial analysis showed that Micro sprayer Irrigation were not feasible to be applied on paddy field tobacco on Madura because the NPV was under zero and the B/C ratio was under 1.   Keywords: micro sprayer, irrigation method, tobacco

Abstract

ABSTRAKLimbah merkuri merupakan suatu limbah berbahaya yang sering digunakan sebagai proses amalgamasi dalam penambangan emas. Dampak dari merkuri akan semakin meningkat terlebih para penambang tidak pernah mengolah limbah merkuri tersebut sebelum dibuang ke lingkungan, sehingga diperlukan suatu metode untuk menjadikan limbah merkuri tersebut tidak beracun atau bahkan hilang. Salah satu metode yang dapat dilakukan yaitu melakukan proses bioremediasi. Pada penelitian ini, proses bioremediasi dilakukan dengan menggunakan bakteri indigenous yang diisolasi dari limbah penambangan emas Tumpang Pitu, Banyuwangi. Bakteri indigenous tersebut didapatkan dengan mengambil sampel berupa sedimen dan sampel cair dari penambangan emas, dan kemudian dilakukan proses isolasi dan seleksi menggunakan merkuri dengan kadar 0-130 ppm. Proses ini untuk mendapatkan bakteri yang resisten terhadap kadar merkuri tertinggi dan mampu untuk melakukan proses degradasi merkuri terbaik. Selanjutnya, dilakukan proses identifikasi bakteri yang terbukti mampu untuk melakukan proses bioremediasi. Penelitian ini memiliki tujuan untuk mendapatkan bakteri indigenous dari limbah penambangan emas pada proses bioremediasi limbah merkuri di suatu lingkungan sehingga tidak berbahaya bagi lingkungan. Hasil penelitian menunjukkan bahwa bakteri jenis Morganella morganii yang resisten terhadap merkuri dan mampu melakukan bioremediasi merkuri hingga mencapai 92.46% ABSTRACTMercury waste is a hazardous waste that often used as an amalgamation process in gold mining. Impact from mercury will increase, especially a miner never to process mercury waste before it is discharged into the environment, so the method is needed to make the mercury waste can non-toxic or even lost. One method that can be done is doing bioremediation process. In this research, bioremediation process was done by using indigenous bacteria isolated from Tumpang Pitu gold mining waste, Banyuwangi. To get the bacteria Indigenous samples taken in the form of sediment samples and liquid samples from gold mining and then processed isolation and selection using mercury with levels of 0-130 ppm. This process is to obtain bacteria that are resistant to the highest mercury levels and are able to perform the best mercury degradation process. Then carried out the identification process of bacteria that proved able to perform bioremediation process. This study aims to obtain indigenous bacteria from gold mining waste for bioremediation process of mercury waste in an environment so as not to be harmful to the environment. It was found that Morganella morganii bacteria were resistant to mercury and able to do mercury bioremediation up to 92.46%
