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

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.

Abstract

Logam Pb atau timbal merupakan logam yang berbahaya bagi kesehatan manusia dan organisme lainnya. Salah satu metode pemulihan kualitas lingkungan yang dapat menstabilkan dan mentransformasi polutan yaitu fitoremediasi. Tanaman rumput raja (Pennisetum purpurhoides) berfungsi untuk meremediasi tanah tercemar Pb. Penelitian ini bertujuan untuk mengamati pengaruh variasi perlakuan pada pertumbuhan dan penyerapan logam pada tanaman. Dalam penelitian ini digunakan perlakuan dengan variasi kadar Pb sebesar 0 ppm, 100 ppm, dan 200 ppm dan penambahan EDTA sebesar 5 mmol selama 8 minggu. Variasi perlakuan cenderung tidak memberikan pengaruh nyata pada variabel banyak daun dan luas daun. Perlakuan memberikan pengaruh signifikan pada peningkatan hasil konsentrasi dan akumulasi tanaman, terutama pada bagian perakaran tanaman. Tanaman rumput raja memiliki nilai BCF (Bioconcentratioon Factor) 1.211 ketika dilakukan penambahan EDTA, dimana rumput raja termasuk dalam kategori tanaman akumulator logam berat. Nilai TF (Translocation Factor)  didapatkan kurang dari 1 sehingga tanaman rumput raja cenderung mengakumulasi logam berat yang diekstrak pada bagian perakaran.

Batu City has a potential livestock (rabbits, beef cattle, and dairy cows). Brau  Village in Batu City is one of the centers of dairy cow farmers and they are the member of business cooperative "Margo Makmur Mandiri" which is a partner with KUD "DAU". The need of concentrate for feed is 60% in addition to elephant grass. Purchasing price of animal feed in KUD "DAU" is Rp.85.000, - per zak @ 50 kg while the animal feed from KSU Rp.75.000/zak with profits 12,000, - up to 20,000/zak. The number of dairy cows in the Brau Village is 500 cows with the need of 6 kg per cow per day.  Therefore at least it is needed 18 tons for 10 days feeding.  Especially during the dry season, the demand is 20-25 tons per 10 days. Technology transfer is required for improving capacity and efficiency of feed production including grinders (cap crusher/hammer mill), genset power plants, conveyor, cyclone and blower. The coaching was pursued about quality standards, marketing and commercial business management. This program can improve the quality, quantity and profits that impact on the welfare of society, especially cow dairy farmers in Brau Village.
