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.

The energy crisis demands the development of an alternative energy that can meet daily needs. The existence of rice straw biomass waste and corncob is a potential to be utilized as bioenergy in the briquettes form. This research was conducted to develop and 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 by carbonation and compaction with starch adhesive by 10%. To know the best quality of briquettes, a mixture of rice straw (100%) was used, mixed rice straw: corncobs (25%: 75%, 50%: 50%, and 75%: 25%), and corncobs (100 %). Test parameters used are ash content, volatile matter content, and calorific value. The results showed that briquettes from corncobs 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 is rice straw briquettes that is equal to 3562 Kcal / kg but has the highest volatile matter and ash content which can decrease the quality of briquette.

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 becomes tasteless. 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 (20cm), silica sand (15cm), zeolite (15cm), and gravel (10cm). laying the reactor upright and tilted 45 degrees. The results showed that the reactor filter was effective in reducing coli 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.

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.

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.

The existence of waste in the environment, especially household waste needs to be addressed by waste management using a simple method, namely waste sorting. The training in this community service aims to: (1) Increase the knowledge of the community of Kedung Sumur Village regarding household waste management. (2) Empowering the community in sorting household waste. The target audience of PPM activities is Mr. and Housewives in Kedungsumur Village as many as 35 people. The PPM activity method uses the lecture method and question and answer discussion. The steps of PPM activities are lectures to explain the concept of the environment, classification of waste, types of organic waste, types of inorganic waste, examples of sorted waste bins. To measure the level of understanding, questionnaire analysis was carried out by the participants. Overall service activities can be said to be good and successful, seen from the success of the target number of trainees (> 100%), the activeness of participants in discussion sessions (> 50%), and the ability of participants in mastering the material seen from the results of the questionnaire, where > 80% participants successfully answered correctly > 5 questions for each category of questions.

Waste has become material considered useless anymore. The rate of waste generation continually increase along with the increase of population, making it increasingly threaten the environment. This situation has been exacerbated by the poor handling of the government and society towards waste. Management of waste sources has become an alternative that can be used to handle the waste problem. The community service program has been carried out in the village of Medalem, Tulangan, Sidoarjo to overcome the occurring of waste problem. The public understanding and awareness of waste issues has been improved through the explanation of material, direct practice and the discussion how to process and sort the household waste. The material that has been explained, includes the waste, the classification of the waste based on its nature, and how to manage waste. It was found out that the Community Service program has improved the public understanding of waste, it was shown that more than 65% of participants had answered the questions correctly. The results of the analysis showed that the public attitude and behavior towards waste problems was good. It was supported by the presence of waste facilities that have been provided by the Village Devices.
