The population of Sidoarjo Regency with a relatively high number and growth rate has consequences for the increase of waste produced volume. Increasing of volume waste is directly proportional to the increase in population, meaning that amount of waste produced is increasing (organic and inorganic waste). The TPA center in one of the garbage collection locations in Sidoarjo Regency has exceeded capacity (overload). This research was conducted with the aim of describing initial model of the distribution of waste used, evaluating initial performance model of waste distribution in Sidoarjo Regency, and providing recommendations to propose improvements in the waste distribution model used. The method applied in this study was using simulation. Based on the simulation results, the Third Scenario proposed the route with the most efficient distance, this affected the vehicle's operational time and the operational costs needed.

Pond is one place that is used as a place to cultivate fish, shrimp, and other aquatic animals that can live in brackish water. Changes in water quality upstream and downstream of the pond due to pollutants may affect the ecological balance of waters. Pollutants can be determined by two simple parameters, the biochemical oxygen demand (BOD) and chemical oxygen demand (COD). While the ability to break down pollutants (biodegradability) can be determined using the ratio of BOD/COD. BOD analysis using the Winkler titration method, whereas the COD analysis using titrimetric method. The value of BOD, COD, and the ratio of BOD/COD in the upstream area is 28.00 mg/L, 60.00 mg/L, and 0,467 respectively. While the value of BOD, COD, and the ratio of BOD/COD in the downstream area is 20.00 mg/L, 43.00 mg/L, and 0.465 respectively. Ratio BOD/COD obtained show that the organic pollutants in the pond is biodegradable.

The batik industry in Indonesia is one of the small and medium business sectors (SMEs) which is a source of work for some people. The batik industry produces various kinds of liquid waste, one of which is dyes including remazol dyes. In this research, clay and bamboo charcoal which are activated by HCl 1 M were made into a composite biosorbent with a ratio of clay and bamboo charcoal (80%: 20%). In this study, two variables are used, namely dose and contact time variation. The results of removal efficiency for variable adsorbent doses and contact time respectively were 30.00% and 31.33%. FTIR spectrum analysis shows wave numbers 1338.64 and 1309.71 cm-1 which is the C-H bending region. The peak at wave number 1539.25 cm-1 with strong and tapered absorption is identified as aliphatic C-C strains which are functional groups of activated charcoal. The spectrum gives a clay-charcoal composite specification when the absorption peak at wave number 3462.34 cm-1 there is an interaction between O-H in clay and O-H in charcoal, causing an increase in absorption intensity. The use of clay and bamboo charcoal biosorbent can reduce levels of dyes in batik industry liquid waste.

Sidoarjo Regency is one of the supporting districts of East Java province. Sidoarjo Regency is experiencing rapid progress because of the development and potential in trade and industry. One of the industries often found in Sidoarjo Regency is tofu factory. The rapid number of tofu craftsmen industry has caused an increase in the volume of liquid waste which also flows into water bodies. The purpose of this study was to determine the reduction in BOD and COD levels for the tofu factory wastewater treatment in the Sepande area, Sidoarjo Regency using a contructed wetland with Typha latifolia as the remediator. The research stage will be carried out using a laboratory scale using acclimatization as the adaptation stage of Typha latifolia and a crontructed wetland reactor as phytoremediation processing. Based on the results and discussion, it can be concluded that there was a decrease in BOD and COD levels in the tofu industrial wastewater in Sidoarjo using the Constructed Wetland system. The percentage reduction in BOD content was greatest in soil media with 3 stems of Typha latifolia plants and a detention time of 4 days of 72%. While the largest percentage reduction in COD levels was in soil media with 2 stems of Typha latifolia plants and 4 days of detention time of 84%.

The development of restaurant businesses in Sidoarjo City is quite rapid, and this will of course be accompanied by an increase in domestic waste originating from a restaurant called greywater. Restaurant wastewater contains a lot of organic content and often without prior treatment is discharged directly into receiving water bodies. The purpose of this study was to determine the reduction in BOD and COD levels for the processing of restaurant wastewater using a contructed wetland with Cyperus Rotundus as the remediator. The research stage will be carried out using a laboratory scale using acclimatization as the adaptation stage of the Cyperus Rotundus plant and the crontructed wetland reactor as phytoremediation processing. Based on the results and discussion, it can be concluded that there was a decrease in BOD and COD levels in restaurant liquid waste using the Constructed Wetland System and Cyperus Rotundus plants. The percentage reduction in the largest BOD content in clay media with the number of Cyperus Rotundus plants of 3 stems gave the highest BOD removal efficiency, namely 70% at 4 days of detention time. While the largest percentage reduction in COD levels in clay media with the number of Cyperus Rotundus plants as many as 3 stems gave the highest COD removal efficiency, namely 67% at 4 days detention time.

Bacterial Polyhydroxyalkanoates (PHAs) are a remarkably versatile category of biodegradable polymers with a variety of applications in the packaging, agricultural, biomedical, and pharmaceutical fields. In the present study, bacterial PHAs films are characterized by Fourier transform infrared (FTIR), Scanning electron microscope (SEM), Gas chromatography-mass spectroscopy (GC-MS), Differential scanning calorimetry (DSC), and Universal testing machine (UTM). It was found that almost 20% (w/w) of PHAs was produced from Ralstonia pickettii, and the five major types of the produced polymer were validated via FTIR analysis, i.e., 1046-1185 cm-1 (C-O stretching), 1723 cm-1 (C=O stretching), 2974-2926 cm-1 (CH3 and CH2 stretching) and 3450 cm-1 (OH stretching). The GC-MS chromatogram generated two main peaks, i.e., 2-butenoic acid methyl ester and 4-hexenoic acid methyl ester, at retention times of 4.62 min and 5.79 min, respectively. The main compounds of 2-butenoic acid methyl ester and 4-hexenoic acid methyl ester had percentage areas of 28% and 43%, respectively. Based GCMS analysis shows two monomer PHAs ie. 2-butenoic acid methyl ester and 4-hexenoic acid methyl ester, correspondingly. The blending of PHAs R. pickettii and PEG-400 positively decreases thermal properties and tensile strength and increases elongation at break.

The objective of this research was to prepare low-cost catalyst for green diesel conversion from vegetable oil. The catalyst of nickel-dispersed biochar (Ni/BC) was prepared by direct pyrolysis of nickel precursor with palm leaves waste under N2 stream at 500 °C. The obtained catalyst was examined by using x-ray diffraction, scanning electron microscope-energy dispersive x-ray, transmission electron microscopy, gas sorption analysis, FTIR and surface acidity examination. The catalytic activity testing was performed on rice bran oil hydrodeoxygenation at varied temperature and time of reaction. Based on analyses, the results showed the successful preparation of Ni/BC with the characteristic of single nickel nanoparticles decorated on surface. The increasing specific surface area of material was conclusively remarked the surface area enhancement by nickel dispersion along with the increased surface acidity, suggesting that the material can be applied for acid catalysis applications. The Ni/BC exhibited excellent catalytic conversion of rice bran oil with the high selectivity toward diesel fraction with 85.3% yield and 92.6% selectivity.
