Attempting to get low price of raw material for producing polyhydroxybutyrate is always studied. Tapioca starch is one of the raw material with low price. The objective of this research was to study the effects of initial ammonium concentration and dissolved oxygen tension (doT) on producing PHB by Bacillus cereus IFO 13690 with tapioca starch as the carbon source. This fermentation was carried out in 5 L fementors with a 2 L working volume, temperature of 30 oC, and agitation of 500 rpm. The pH medium was controlled at 5.6 after it came down from the initial pH of 6.8. Meanwhile, the initial doT was 100 % air saturation and also came down to and maintained at doT of experiment, i.e. 1 , 5 , or 10 % air saturation. The best result was obtained when the initial ammonium concentration was 5 g/L and the doT value maintained at 5 % air saturation. By this conditions, the cell growth reached 5,457 g cell dry weight/L containing PHB of 2.42 % cell dry weigh after 29 hours fermentation.

TPA Benowo is a final disposal site for solid wastes generated by Surabaya community, located at KelurahanRomokalisari, Kecamatan Benowo Kota Surabaya. Every day nearly 1,200 tonnes of wastes are thrown intoTPA Benowo. This site was prepared with a land of approximately 39,7 hectares. The recent problemencountered by TPA Benowo is the leachate from the dump site that is normally discharge into Kali Lamong,now it turned out that such leachate is far above the allowable limit. Water is said to be turbid if it containslarge amount of suspended particles. Reduction of turbidity is normally done by filtering it through sandmedia. Clampshells offer an alternative for use as water filter media.This was a quasi-experimental study, using three different diameter, 1 mm, 0,5 mm, 0,3 mm. As much as 24samples were examined in this study, they were grouped into prior-to and after treatment groups, and acontrol group Sampling was performed in the morning to avoid excessive sunlight. Water was filtered throughon the same day, and followed by shipment to the laboratory right away. Data were tabulized, processedintographs, to facilitate descriptive analyses.The study found that one particular clampshell, kerang Tothok, at a diameter of 1 mm was proven to be mosteffective during treatment C, marked as 94,5% with recorded detention time of 90 minutes. Those havingdiameter of 0,5 mm is most effective during treatment C, marked at 95,8 % with recorded detention time of90 minutes. The 0,3 mm diameter is most effective at treatment C, marked at 85,7 % with recorded detentiontime of 90 minutes. The study concluded that the most effective diameter as a clampshell granules filtermedia is 0.5 mm, with reduction of 369.62 NTU or 95,8%. Further investigation is needed to learn theappropriate thickness of the clampshell granule filter.

Water purification is typically carried out using chemical coagulants like Tewes. localname for Aluminum sulfate. In many parts of the world experts are looking into coagulantmaterials derived from plants. Among many of them is the Moringa seeds. Moringa seedscontain water-soluble proteins, when crushed and dissolved in water it will form a positivelycharged solution. Electrophoreses Test proved that positively charged solution were alsoresulted from the use of Salak seeds and Papaya seed. The purpose of this study was toanalyze the differences in coagulation using Moringa (Moringa oleifera), Salak (Salaccazalacca), and Papaya seeds (Carica Papaya).The study was performed in a quasi-experimental set up exercising a pretest-posttestdesign. The object for the study was water sample taken from a river used by the communityin kecamatan Krembung for their water source. As much as 1000 ml of river water was used ineach test run. Test containers were treated with natural coagulants. Coagulant materials usedin the tests were Tawas powder, Moringa, Salak, and Papaya seeds at a dose-series of 50 ppmto 1000 ppm. The resulted data were analyzed using Kruskal - Wallis Test.There was a significant difference with regard to optimal dose of the natural coagulantsas well as the percentage of turbidity reduction. The optimal dose for Moringa seeds was 130ppm with a percentage of reduction at 97,3% that reduced turbidity down to 2.7 NTU. Theoptimal dose for Salak seeds was 100 ppm that resulted in a percentage reduction of 89,2%and reduced the turbidity down to 10.9 NTU. The optimal dose for Papaya seeds was 50 ppmwith a percentage of decline at 83,4% reducing the turbidity down to 16,7 NTU. Moringaseeds coagulant has maximum turbidity reducing capability, while the other two naturalcoagulants, Salak and Papaya seeds, were not in their maximum levels of turbidity reducingcapabilities.At a dose of 200 ppm Moringa seeds exhibited a greater ability as a coagulant inlowering water turbidity compared to the other natural coagulants, Salak seeds at a dose of100 ppm and Papaya seeds at a dose of 50 ppm. The study concluded that Moringa seeds canbe applied as a substitute for chemical coagulants provided they are used within 1 x 24 hours.Key Words : Turbidity and Coagulant

Fish is an example of perishable food. To prevent fish from deteriorating quickly, proper handlingis required during storage to extend the shelf life, among other things, one of which is by the addition ofpreservatives. the extension of food shelf lives, people often misused formaldehyde as a foodpreservative. Formaldehyde itself is banned for use as food ingredients as it may be harmful to humanhealth, such as irritation of the stomach, its carcinogenic properties (causing cancer), and may bringabout death.This was an experimental study using one group pretest-posttest design to investigate the effectof soaking water on the reduction of formaldehyde levels in cobs. There were 48 samples in 6replications of each treatment group. The dependent variable in this study was the formaldehyde levelsin cobs and the independent variables was the type of soaking water (tap water, hot water attemperature of 50 DCand 5% vinegar), soaking were exercised for 30 minutes. The data were analyzedusing paired t test and Anova test.The result showed that all three types of soaking water were able to reduce levels of formaldehydein cobs, where tap water reduced formaldehyde level by 53.7% at p a (0.05), hot water attemperature of 50 DCreduced formaldehyde level by 62.6% at p a (0.05), and vinegar 5% reducedformaldehyde level by 42.4% at p a (0.05). The Anova test between treatment groups indicated thatsoaking water resulted in a value of p a (0.05)It can be concluded that types of soaking water have no effect on the reduction of formaldehydelevel in cobs. However, there were significant differences in reduction of formaldehyde level before andafter the soaking treatment. The stydy suggested that further research needs to be conducted on otherfish samples using different concentration of soaking water and soaking time.

Water can be regarded as one of the sources of life. The absence of water maythreaten the very survival of the ecosystems and all living creatures. In addition to dailyconsumption, water is also used for bathing and washing. Normally, water can easily beobtained provided there is no special event such as a natural disaster, where victims of suchemergency will suffer from lack of potable or drinking water, despite the amount of aidsprovided by the government. Among other things, the government have introduced a mobilewater treatment unit. This study was aimed at understanding the efficiency of such a mobileunit in providing water in disaster areas.This was a descriptive study to present results of field observations and other datagathering methods in tables and other forms for comparison with relevant and appropriatestandards. In addition to field observations data collection was carried out through interviewsand measurements. The object under study was a mobile treatment unit owned and operatedby the Badan Penanggulangan Bencana Oaerah (BPBO).Results of the investigation indicated that the mobile unit was being operated inefficient and effective manners in satisfying the need and demand for potable and drinkingwater. The treatment system in the mobile unit relied on Reversed Osmoses (RO) processes.The amount of water generated by this unit was 1000 L/hour for potable water and 600 L/hourfor drinking water. Results of the microbiological, physical and chemical examinations havesatisfied the designated requirements and standards.The study suggested that all relevant staff should be able to operate the unit, as well asinitiating manageable repairs when such things are called for. Minor problems pertaining to theunit can be solved on site and this may lessen the dependence on ouside assistance. The unitworks quite well, therefore efforts should be directed at managing supplies, maintenance, andto provide pretreatment unit to improve unit's capability to treat raw water having turbidity ofmore than 30 NTU.Keywords: disaster, emerpency. mobile water treament unit
