Abstract

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.

Abstract

Sludge from citric acid industry can be purified to be gypsum. Purification was done by calcination process at the condition 1 atm pressure and 110 °C of temperature to get calcium sulphate hernihydrat or Plester de Paris. Calcium sulphate specification that we got are grew color, hygroscopis, unsoluble in water, unflammable, and will be hard if mixed with water.

Abstract

The living environment must be managed in order that it may be in harmony with the concept of sustainable development. Heavy metals is one of a toxic materials including on the list a hazardous and toxic waste relation by a Government Regulation. The pollution a heavy metals in the water area increase by industrial activities, where to discharge they waste to the ilegal dumping. Effect accumulation of a heavy metals in the marine biota such as fish, kind of mollusca (anadara sp), etc was absorbed, to caused a hazardous and toxic, that may endanger the environment and the health of human beings.

Abstract

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.

Abstract

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.

Abstract

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.
