The energy crisis demands the development of an alternative energy that can meet daily needs. The existence of rice straw biomass waste and corn cob are potential to be utilized as bioenergy in the briquettes form. This research was conducted to develop and to test the characteristics of biomass briquettes as alternative fuels. Biomass used in this research is rice straw and corn cob. The making of briquettes is done through carbonation and compaction with 10% starch adhesive. To know the best quality of briquettes, a mixture of rice straw (100%) was used, mixed rice straw:corn cobs (25%:75%, 50%:50%, and 75%:25%), and corn cob (100 %). Test parameters used were ash content, volatile matter content, and calorific value. The results showed that briquettes from corn cobs were the best briquettes from ash content and volatile matter content of 9.52% and 9.7% respectively. While based on calorific value, briquettes with highest heating value was rice straw briquettes which was equal to 3562 Kcal/kg. Keywords: Biomass Briquette, Rice Straw, Corn cob, Ash Content, Volatile Matter, Calorific Value, Bioenergy.

Seawater intrusion causes groundwater in coastal areas to be brackish, so it requires special processing to remove salt levels in raw water so that the water becomestasteless. In addition to salinity, the presence of bacteria in water can cause disease if consumed without proper processing. Brackish water treatment called desalination can be done by ion exchange using an activated carbon filter. The purpose of this study was to determine the efficiency of the performance of brackish water processing filters in setting aside water quality parameters in the form of: coli bacteria and total bacteria expressed in the Total Plate Count (TPC). The filtration reactor is made using filter media in the form of activated charcoal (20 cm), silica sand (15 cm), zeolite (15 cm), and gravel (10 cm). laying the reactor upright and tilted 45 degrees. The results showed that the reactor filter was effective in reducing Coliform bacteria and total bacteria in raw water up to 100% and 97%, respectively, although it did not meet drinking water quality standards PERMENKES No.492/Menkes/Per/IV/2010. Both reactor variations have performance effectiveness that is not significantly different in processing raw water, but overall reactors with upright variations have better performance. Keywords: Active Carbon Filtration, Coliform, Total Plate Count.

Biofilm is proven to be effective to be used in water and wastewater treatment. Different raw water’s organic compound contents will affect to the heterogenity of the biofilm. This heterogenity is caused by different abilities of the microbial biofilm constituent in decomposing organic coumpound in raw water. Analysis of structures and components can be done to study the heterogenity of the biofilm.This analysis is not only able to describe the quantity but also the quality of the biofilm. The purpose of this review is to compare the various techniques in analyzing the structure and components of the biofilm. Analysis techniques can be performed with image analysis, chemical analysis, biochemical and population analysis. Method that commonly used is the image analysis by Scanning Electron Microscopy (SEM) to observe the structure of the biofilm. Chemical analysis using colorimetry, and analysis of total protein is using Lowry’s method and Bradford’s method, and molecular analysis by PCR that is used to characterize the components of biofilm’s constituent.

Waste is a global problem that is very hard to solve. Waste generation produces leachate that is harmful to the environment. Leachate can seep into the soil causing direct soil and groundwater pollution. Phytoremediation is an effort to use certain plants and their parts to reduce chemical substances in waste and environmental pollution problems. In this study, the plants used were Typha latifolia by varying the number of plants: without plants, four, and five plants. The leachate used comes from the Griyo Mulya landfill, Sidoarjo. The reactor used was 30´30´50 cm and the discharge used was 15 L/day. The reactor used is a continuous system. The parameters analyzed included TDS and NH3. The results showed that the most significant decrease in TDS and NH3 levels was obtained from the reactor of four and five plants with 700 mg/L of TDS and 10.65 mg/L of NH3.

Allowance for COD content in raw water can use a dual media sand filter. Sand filters have various advantages, namely low-cost and environmentally friendly operational costs and are able to produce quality processed water that meets quality standards. This study uses a dual media sand filter with dimensions of sand and gravel depth of 40 cm and 20 cm respectively, running the reactor for 15 days (sampling every 2 days) with 14 days of acclimation. The purpose of this research is to obtain the optimum flow rate from the sand filter reactor in setting aside COD in raw water. The results showed a dual media sand filter reactor unit with a flow rate of 0.3 m3 / m2.hour has a higher efficiency in setting aside COD compared to a reactor with a flow rate of 0.2 m3 / m2.hours which is 52.3%, where the magnitude This removal efficiency is influenced by biological processes in the form of bacterial activity in the schmutzdecke layer and chemical processes in the form of adsorption.

Sidoarjo is one of the largest fish-producing districts in East Java. The high productivity of fisheries is in line with the increasing amount of waste produced. Both solid waste and liquid waste. Generally, liquid waste comes from water used for washing fish, usually brownish, cloudy and smells fishy. In addition, the concentration of organic matter is very high in the waste. The purpose of this study was to determine the reduction in levels of Total Suspended Solid (TSS), Total Dissolved Solid (TDS) and Biocamical Oxigen Demand (BOD) in these wastes using Scirpus grossus. The independent variable used is the variation in the number of plants (without plants, 5 plants and 10 plants). The waste used comes from the Fish Market Depot Kab. Sidoarjo. The research begins with the acclimatization process, then the phytoremediation test is carried out. Based on laboratory analysis, it was found that the best decrease in TSS, TDS and BOD was obtained from the reactor with 10 plants.

The raw water used as drinking water is currently contaminated with industrial, domestic, and agricultural waste, resulting in high concentrations of nitrogen, phosphate, detergent, COD and pesticides. Slow sand filters can be used as an effort to treat drinking water. This study aims to determine the effect of the variables used on the reactor performance for the removal of COD and BOD nutrients. In this study, the variation of gravel (with and without gravel) is used, so that the performance of each type of reactor can be seen. While the parameters to be measured are COD and BOD. The results showed that SSF gave a good reduction performance in reducing BOD up to 60% and COD up to 68.33% on the 6th day.
