Abstract

Oyster mushroom as a source of nutritious food and medicinal source is known since Chow Dynasti in China.However, its potential for environmental rehabilitation as known as mycorestoration is being investigatedby Paul Stamets in 2005. If oyster mushroom can control the world that could support from the smallestthings as food becoming bigger roles in the future, such as poverty eradication, improving soil fertility, andrehabilitating environmental condition, degrading toxic pollutant, protecting human health from diseases,and helping community to integrate complex waste recycle, so oyster mushroom is emerging as a strongcommodity to improve our welfare. This paper is trying to promote the role of oyster mushroom to provideits strength for both as nutrious food and medicinal source, and also for its ability to restore degraded soilfertility, and improving to remediate contaminated soils. In line with those things, and the most importantfor the people of Indonesia is trying to help increase their income through promoting mushroom cultivation,because Indonesia has a hugh potential for lignocelluslose materials and agricultural waste, and then itsspent mushroom can be used for animal feed and soil amelioration and soil remediation. Based on theStamet investigation this spent mushroom can be used for environmental rehabilitation of toxic pollutantssuch as PCB (Polychlorinated Biphenils), PAH (Polycyclic Aromatic Hydrocarbon), Azo dyes, and otherpersistent organic pollutants (POP?s).Key words:  Oyster mushroom, Pleurotus ostreatus, mycorestoration, soil remediation, environmentalrehabilitation.

Abstract

Reformation democracy guides Indonesian government in one decade of duration, even a little bit more, and also in that time it brings the autonomy region existent with aims to spread out development. Based on this concept that the justice of development of every region can be achieved no exception, and then Indonesian government is able to be an advanced country. Due to Indonesian wish to be an advanced country, the academic society right now has very critical opinion to discuss on ever any scientifi c meeting about how to measure the achievement of a good government performance. To evaluate government performance, an instrument is needed to measure governmentactivities, which that measurement must be based on the determinant object. In this case that the determinant object is an environment of entrepreneur as indicator of measurement. The output of measurement can be used as well as input to government to make decision, then implication of policy can be made. In order to apply that instrument, so must be taken an sample district ascase i.e ?Pemerintah Kota Bekasi?. The conclusion of this assessment are : Public services for permission of trade in Kota Bekasi must be improved. Public services in specifi cally for wealth of intelectual right must be improved(clearly in law). A minimum substance wage of district / region must be improved. Rearrangement to taxation has to soon be done. There is more information about assessments conclusion.Ket words : Model, environment of entrepreneur

Abstract

Onggok merupakan sisa dari proses penyarian singkong dengan cara pengepresan dalam produksi tapioka. Komposisinya yang didominasi oleh pati dan serat kasar membuka peluang pemanfaatan limbah onggok sebagai medium fermentasi padat untuk produksi PUFA. Periptaan PUFA secara biologik lazim menggunakan kapang Aspergillus. Aspergillus mampu menghasilkan asam lemak menyerupai asam lemak yang diperoleh dari minyak kelapa sawit, yakni linolenat dan linoleat. Kapang Aspergillus juga dikenal memiliki kemampuan mendegradasi bahan organik termasuk limbah sehingga berpotensi untuk diterapkan dalam mengolah limbah onggok, ampas tahu, molase serta dedak padi. Dengan memanfaatkan onggok sebagai media fermentasi padat seta sumber karbon dalam produksi PUFA maka terdapat potensi pengurangan biaya operasional dalam produksi PUFA. Hal ini akan meningkatkan keunggulan daya saing dalam produksi PUFA termasuk meningkatnya aspek kinerja dari sudut pandang lingkungan. Memanfaatkan limbah sebagai bahan baku dalam proses produksi merupakan penerapan nyata konsep waste to product atau waste exchange dalam membangun industri proses yang selaras dengan kaidah Sustainanle Consumption and Production. kata kunci : onggok, asam lemak tak jenuh, fermentasi padat, waste exchange, sustainable consumption and production, kualitas lingkungan

Abstract

This research is aimed at overcoming the limited forage problem at marginal land that adversly affects the sustainability of forest. The research was done at Gerokgak District, Buleleng Regency, Bali Province from April 2010 until March 2011. Because the feed problem is complex and dynamic, systems dynamic modelling was used as the method. This method supported with participatory rural appraisal methods for system identification, mean absolute percentage error method for analysis validity of model, and sensitivity analysis to determine the scenarios of feed scenarios. Simulation results showed that the feed available on the actual conditions (in 2009) is only able to meet 64.5% of the total feed required, and potentially to 48.5% in the long term (year 2034). In that period, the feed supply of 52,629 tons / year increased to 74,886 tons/year while consumption increased from 81,403 tons/year to 155,834 tons/year, thus it potentially increases the damage of forest because the burden of forests as the source of feed would increase from 35.5% to 51.5%. To overcome these problems, five scenarios was developed to increase the feed supply. From the five alternative scenarios, the highest increase of feed supply successively given by Scenario 2 (planting field boundary with forage plants), followed by Scenario 1 (introducing the new technology in maize and rice cultivation), Scenario 5 (building feed storages), Scenario 4 (increasing the number of forest community groups from four to 14) and the last is the Scenario 3 (plantingcorn in the dry season by utilizing irrigation ponds) Those scenarios give the potential additional supply of feed 51.6%, 30.1%, 10.1 %, 3.1% and 0.1% respectively. Partially, no single scenario can provide sustainable feed supply; to do so the combination of at least two scenarios must be implemented.keywords: forage supply model, Bali cattle, marginal land, system dynamicRai

Abstract

Clean water to poor communities who live in crowded municipal area is stillexpensive and a luxury. This condition is evidenced by the number of people whouse ground water for their daily water, because water taps still seems expensivefor them. Diarrheal disease is still relatively high for Indonesia, where nearly 16thousand people suffer from diarrhea due to poor sanitation. To help the poor inthe city, there are several alternative technologies that can be applied to publicaccess to clean water and adequate low-cost, including ground water treatmenttechnology with a filter system equipped with an ultraviolet sterilizer, or ozonegenerators, or using ultrafiltration, if possible can also use the reverse osmosismembrane that for fresh water. Arsinum is the best alternative should be chosenfor fulfilled potable water in slump area.Keywords : Sanitation, water treatment technology, portable water, low-cost, slump area

Abstract

Kualitas air sungai harus tetap dijaga dari pencemaran dengan pengelolaan dan pengendalian yang bijak. Beberapa zat pencemar di sungai yang harus dikendalikan adalah nitrit, nitrat dan fosfat. Jumlah nitrit, nitrat, dan fosfat yang berlebihan akan merugikan karena berpengaruh terhadap kesehatan dan biodiversitas ekosistem perairan tersebut. Salah satu upaya pengendalian pencemaran zat pecemar tersebut adalah fitoremediasi menggunakan rumput vetiver dengan sistem pulau apung. Vetiver ditumbuhkan pada tiga pulau apung yang berbentuk persegi panjang dengan panjang masing-masing 4,5 m. Pulau apung ditempatkan pada badan sungai. Akar vetiver yang tumbuh dibawah permukaan air sungai akan menyerap berbagai bahan pencemar. Pengambilan sampel air dilakukan pada ketiga ujung awal dan akhir pulau apung (inflow dan outflow) untuk mengetahui perubahan kadar nitrit, nitrat, dan fosfat yang dipengaruhi oleh akar vetiver. Jarak pengambilan sampel adalah 4,5 m, 9 m, dan 13,5 m. Pulau apung dengan rumput vetiver yang diujicoba mampu menurunkan jumlah nitrit, nitrat dan fosfat. Penurunan optimum terjadi pada nitrat yang mencapai 18% dengan jarak pengambilan sampel pulau apung 9 meter. Tiga jarak pengambilan sampel awal dan akhir pulau apung yang berbeda efektif untuk menurunkan fosfat.Kata kunci: nitrit, nitrat, fosfat, pulau apung, rumput vetiver
