Fenol is a hazardous substance that can pollute the environment. Traditional herb Industry is one of industries produces liquid waste with high pollution level, the fenol content more than 9 mg/L. Biological treatment with anaerobic activated sludge method is one effective way of processing waste.This research was aimed to study the effect of MLSS variable and fenol load, the efficiency of fenol decrease in anaerobic waste processing system. The experiment is conducted by synthetic herbs waste with COD content of ± 3610 mg/L, retention time of 6 hours at a temperature of 30oC, atmospheric pressure in anaerobic baffle reactor continuously. The reactor volume is 60 L, the MLSS content of 3000; 4000; 5000 mg/L, fenol load at 0, 3, 6; 9; 12 mg/L. Result of research show that active sludge of mixture breeding from cage manure effective for the processing of waste with the low rate fenol (less than 6 mg/L) with the efficiency of degradation fenol 89,7-99,87% but less be effective at high burden fenol (more than 6 mg/L) with the efficiency of degradation fenol equal to 18-52%. The results obtained compared well with other reduction process.

Bioethanol is one type of biofuel that developed significantly. The utilization of bioethanol is not only limited for fuel, but also could be used as material for various industries such as pharmaceuticals, cosmetics, and food. With wide utilization and relatively simple production technology has made bioethanol as the most favored biofuel currently. The use of lignocellulosic biomass, microalgae, seaweeds, even GMO (Genetically modified organisms) as substrates for bioethanol production has been widely tested. Differences in the materials eventually led to change in the production technology used. Pretreatment technology in the bioethanol production using lignocellulosic currently experiencing rapid development. It is a key process and crucial for the whole next steps. Based on the advantages and disadvantages from all methods, steam explotion and liquid hot water methods are the most promising pretreatment technology available.

One of the largest applications of detergent is for cleaning clothes. By society, waste water containing detergent dumped directly into the ground or river. This can lead to pollution of soil or river so that can degrade the quality of the environment. Wastewater treatment has been carried out by the community one of them using the well diffusion because it is cheap. The downside of this treatment is not suitable to be applied in areas with high groundwater level and swampy areas. This study aims to determine the efficiency of wastewater treatment by anaerobic filter and up flow detergent acclimatization activated sludge. Anaerobic system is a biological process that uses the activity of microorganisms that can grow and live in environments without oxygen. Anaerobic bacteria living in the stone surface and oxidized past wastewater. The method used was neutralized waste water until the pH 7 followed by adding it to anaerobic tank and closed. Inside anaerobic tank occurred inoculation by activated sludge and remaining it until 6 days. The temperature then must be watched between 37oC – 40oC in order of successfully acclimatization and it’s indicated by formation of gas. After acclimatization, the wastewater in anaerobic tank was stream down to up flow anaerobic filter through bottom to the top of the tank. The sample was then retaining in 2, 4, 6, 8, 10, 12 and 14 days followed by the detergent content analysis. The result showed that it could degrade the detergent rate from 21,03 mg/L to 3,83 mg/L and the efficiency until 81,8 % with the maximum retention time was 14 days.

Edible film based on beeswax and carrageenan has been made using two types of plasticizers namely glycerol and sugar. Glycerol at a fixed concentration of 1% was combined with sugar (fructose, glucose and sucrose) each at three concentration levels of 0.5%, 1% and 1.5% w /vt. Edible film has water content, thickness, tensile strength, elongation and vapor transmission rate respectively 13.69-14.91%, 0.059-0.102 mm, 12.62-32.40 MPa, 13.34-43.57% and 17.65-25.38 g/m2/24 hours. The enhancement in plasticizer concentration resulted increasement of moisture content, thickness, elongation and water vapor transmission rate but decreased its tensile strength. All edible films showed lightness in range 84.45-85.61. Edible films with glycerol-sucrose plasticizer showed the lowest lightness. The scanning electron microscopy results indicated that edible films treated with plasticizer glycerol-fructose and glycerol-glucose have more homogeneous and smoother surface than edible control films and edible films with a glycerol-sucrose plasticizer.Keywords: edible film, fructose, glucose, plasticizer, sucrose ABSTRAKEdible film (lembaran tipis dapat dimakan) berbasis karagenan-lilin lebah telah dibuat dengan menggunakan dua jenis plasticizer (bahan pemlastis) yaitu gliserol dan gula. Gliserol pada konsentrasi tetap 1% dikombinasikan dengan gula (fruktosa, glukosa dan sukrosa) masing-masing pada tiga level konsentrasi yaitu 0,5%, 1% dan 1,5% b/vt. Edible film mempunyai kadar air, ketebalan, kuat tarik, elongasi dan kecepatan transmisi uap air masing-masing sebesar 13,69-14,91%, 0,059-0,102 mm, 12,62-32,40 MPa, 13,34-43,57% dan 17,65-25,38 g/m2/24 jam. Kenaikan konsentrasi plasticizer menghasilkan kenaikan kadar air, ketebalan, elongasi dan kecepatan transmisi uap air namun menurunkan kuat tariknya. Semua edible film menunjukkan sifat warna yang baik dengan lightness antara 84,45-85,61 sedangkan edible film dengan plasticizer gliserol-sukrosa memperlihatkan lightness paling rendah. Hasil scanning electron microscopy menunjukkan bahwa edible film yang diberi perlakuan Plasticizer gliserol-fruktosa dan gliserol-glukosa memiliki permukaan yang lebih homogen dan halus daripada edible film kontrol dan edible film dengan plasticizer gliserol-sukrosa.

So far, most of West Kalimantan cocoa beans sold raw to collectors in Malaysia at a price that is less competitive, so it was necessary to study the processing of cocoa into chocolate bars with products utilizing palm fat as a fat substitute. The purpose of this study was to determine the effect of the formulation of palm fat and cocoa fat on the physical properties of chocolate bars. The research was conducted by varying the concentration of palm fat to total fat namely 0%, 25%, 50% and 75%. The products were tested on melting point and hedonic. Based on research data it can be concluded that the treatment of palm fat concentrations to total fat by 25% produces chocolate bars with a melting point of 36.0 ° C and preferred by the panelist.
