Sep[erti telah diketahui bensin bertimbal merupakan penghasil bahan berbahaya SPM dilingkungan pada sektor transportasi, dimana dilain pihak dapat menimbulkan banyak problem kesehatan seperti menurunnya IQ, kanker, cognitive effect dan sebagainya. Ternyata bensin tanpa timbal lebih efisien dalam penggunaan dan memelihara kualitas lingkungan.

In Indonesia, pesticide formulation mostly used is Emulsifiable Concentrate (EC). In order to get a suitable formulation in application, effective in use, stable in certain period of time and economically, stabilization of emulsion become an important thing. The stabilization is influenced specially by variety and optimum amount of emul sifier used. The Industry has been interested in emulsions stabilized by blends of anionic and nonionic emulsifier.

Lim bah industri klor alkali termasuk limbah 83 dari sumber yang spesifik. Pembakaran lirnbah padat industri kimia terpadu, yang memproduksi kaustik soda, VCM dan PVC akan menghasilkan abu. Limbah cair media proses polimerisasi PVC setelah pengendapan disebut spent pure water (SPW). Abu sisa pernbakaran, Solid Waste /ncenerator (SWI) ini dapat dimanfaatkan sebagai adsorben untuk SPW. Sesuai dengan model Freundlich isoterm, SW! mempunyai daya adsorpsi terhadap biru metilen lebih baik dari pada karbon aktif, dan mampu menurunkan turbiditas SPW sampai sekitar 95%.

The adjuvant usage gives an effect in the Water Dispersible Granule of pesticide formulation, both for types of adjuvant or its concentration. Binding agents as a part of adjuvant use in this research are Poly Vinyl Pirolidone, Poly Vinyl Alcohol, CMC and Gum Arabic. The best sequence formulation for water dispersible granule on active ingredient, speed of desintegration and pH (before and after storage) is A1 formula with polyvinyl pirolidon 2 %, A2formula with polyvinyl pirolidone 2,5 % and B1 formula with CMC 2,0 %. Generally the result shows that the local binding agents give a bit lower performance as adjuvant compared with the existing water dispersible granule formulations.

The Function of stabilization is to decrease leachate or chemical reaction which is potential to produce pollutant from waste. Three kinds of stabilization such as addition of the cement, lime and organic sludge had been done before. The result showed that the sludge can bind heavy metal. Analysis result showed that the decrease 'in presentation of heavy metal are Zn (79%), Cu (83,5 %), Fe (99,97 %), Mn (JOO %) and Cr (98,2 %). This experiment is continued to find the optimum amount of cement added to the sludge. The result showed that by addition of 5 % cement in textile sludge can hold the heavy metal.

As the first step in tackling environmental issues related to the protection of the ozone layer have been reviewed internationally. In Indonesia under the "Law concerning the Protection of the Ozone Layer by Means of Regulation on Specified Substance", regulations on the production and importation of controlled CFCs have been enforced since March 1991. The problems with CFCs are primarily environmental. CFCs destroy the stratospheric ozone layer that protects people from harmful ultraviolet rays from the sun. Already, holes and breaks in the ozone layer are apparent to scientists. Without the ozone layer's protective shild, skin cancer and eye damage are more likely among people,and the marine food chain could be profoundly disrupted. In addition, CFCs are responsible for about one-fifth of the greenhouse gases emitted into the atmosphere every year.

Energi yang dihasilkan dari pembakaran limbah padat industri gula berupa bagas dengan tungku pembakaran yang didesain sedemikian rupa dapat memanaskan air menjadi steam dengan suhu ruang bakar 435°C dan suhu steam 140°C. Steam yang terbentuk disimpan di header. Header dapat menyimpan steam yang dihasilkan dari pembakaran bagase secara kontinyu 10 kg/jam suhmaksimum yang dapat dicapai 150°C dan tekanan maksimum 4-5 kg/cm2. Panas yang hilang dari cerobong gas buang digunakan untuk alat pengering hasil agro yang didesain khusus. Suhu diruang alat pengering dapat dijaga konstan 70°C sebagai mana yang dibutuhkan.
