Abstract

The larvae BSF (black soldier fly) can be used as an insect-based organic waste recycling technology. Not only for recycling organic waste, BSF larvae (black soldier fly) can also convert organic waste into a product in the form of compost. With so many waste problems, this technology is the most relevant way to deal with the problem. The purpose of this study was to examine the use of BSF (Black Soldier Fly) larvae in the composting process and to find out how much BSF (Black Soldier Fly) larvae were able to reduce organic waste. This study used an experimental method using 16 reactors containing 10000 larvae eggs in each reactor and using a variety of mixed waste. The variation used is the initial weight, in this study used an initial weight of 3 kg and 4 kg and treatment was carried out 2 times. The frequency of feeding was carried out every 3 days and then the weight reduction of the remaining waste in the reactor was measured after harvesting. The average percentage reduction in treatment 1 with an initial weight of 3 kg of waste is 18.25% while the initial weight of 4 kg of waste is 53.65%, different in treatment 2 the average percentage of waste reduction at an initial weight of 3 kg is 60 .25% and at 4 kg by 30.25%. The results of the compost will be compared with the quality standard of SNI 19-7030-2004, the results of the study show that treatment variation 2 at the initial weight of 3 kg of waste is closest to the quality standard based on the value of pH, water content, C-organic, N-organic and C ratio /N.

Abstract

Gresik is one of the several centers of the snacks industry. In order to assure food quality and safety, analysis is required to address hazards during the production process. Pudak were made by heating coconut milk, then combined with flour, rice flour, sugar, salt, water, and pandan suji leaves. Pour heated coconut milk over the top, whisked until it is smooth and with no lumps, add cooled coconut milk and vanilla, cover the mixture in leaf wrap, and steam for one hour before serving. This study was carried out to identify and minimize hazards during the production process of pudaks (one of traditional food) and provide recommendations for establishing the Hazard Analysis Critical Control Point (HACCP) system. During the production process, there are three different kinds of possible hazards: biological, physical, and chemical. The Critical Control Point (CCP) might be acknowledged, allowing for a comprehensive implementation of the HACCP. In this publication, the dangers of CCP were analyzed along with suggestions for reducing them.

Abstract

Indonesia is one of the largest palm oil-producing countries globally, with a production value of 40 million tons by 2020. Biodiesel is one of the alternative energy sources that can be processed from palm oil. Diesel engines can directly use biodiesel as a fuel. Biodiesel has distinct characteristics from diesel; thus, it will affect performance and other things on the engine. In this research, diesel engine performance tests were carried out, including specific fuel consumption (SFC), cylinder head temperature, cylinder block, and exhaust pipe, with a test time of 300 hours. This research aims to determine the effect of the cylinder head, cylinder block, and exhaust pipe temperatures on SFC using two different fuels, i.e., B100 and B20. Based on the test results, the average cylinder head, cylinder block, and exhaust pipe temperatures on the B100 engine are 136 oC, 130 oC, and 257 oC. As for the B20 engine's cylinder head, block, and exhaust pipe temperatures are 139 oC, 132 oC, and 264 oC. Engine with B100 fuel obtained SFC of 0.317 kg/kW.hour and engine with B20 fuel obtained SFC of 0.276 kg/kW.hour. In general, the combustion temperature in the cylinder head affects the increase in SFC in both engines with different fuels; the higher the combustion temperature in the cylinder head, the higher the SFC is. Engines with B100 fuel have a higher SFC value than B20 fuel, which is influenced by the higher viscosity and density values; thus, the droplets from the fuel atomization process become larger when compared to fuels with lower viscosity and density values. The graph analysis shows that the cylinder block temperature graph on the B100 and B20 fueled engines decreases between temperatures of 133-134 oC, then inflates with the increase in specific fuel consumption. The higher temperature compared to the B100 fuel engine makes the fuel undergo complete combustion when injected into the combustion chamber due to atomization or very fine droplets burning completely. The cylinder block temperature chart on the B100 and B20 fueled engines has a very significant trend difference. B100 engines tend to experience a decreasing trend in temperature along with an increase in SFC, while B20 engines tend to experience an increasing temperature trend along with an increase in SFC.

Abstract

Hydroxyapatite (Ca10(PO4)6(OH)2) is one of the biomaterials that can be used for replacement bones for survivors of fractures that can be caused by accidents or natural disasters. Hydroxyapatite biomaterials are now a necessity, but the high price of imported hydroxyapatites has resulted in difficulties in obtaining them. The purpose of this study is to synthesize calcium phosphate from the eggshells of purebred chickens so that they can be used as raw materials for making hydroxyapatite. The stages in the manufacture of calcium phosphate are calcination as a pretreatment process of purebred chicken egg shells which is continued with the synthesis process. The research variables used are variations in phosphoric acid concentrations and also pH variations. The results presented were regarding calcium content through XRF analysis, diffraction patterns from calcium phosphate through XRD analysis, and morphology of calcium phosphate through SEM analysis. From the results of the analysis, it can be used as a reference for the characteristics of calcium phosphate which will be used as a raw material for making hydroxyapatite.

Abstract

The coast of Tuban is a fairly dynamic area, where the lives of fishermen depend on fishing efforts. Ecosystem changes that occur in the coastal area of Tuban greatly affect the fishing effort, where one of the parameters that can be observed is the distribution of oxygen content from water bodies on the coast. The purpose of this study was to analyze and map the distribution of acidity content (pH) and its correlation with dissolved oxygen in the coastal area of Tuban. This is based on the fact that research on the distribution of dissolved oxygen has been carried out by many experts, as well as the acidity value of seawater, there have also been those who have done it, only here that needs to be emphasized, that there have not been many dissolved oxygen studies involving other parameters such as acidity pH.

Abstract

Barium sulfate scale grew on industrial oil equipment make damaged either in injection or producing wells. A series of experiments were performed to estimate the precipitation rate of barium sulfate in laboratory equipment from brines containing the concentration of barium ions (3500 ppm) and varying concentrations of calcium and magnesium ions (10 and 20 ppm). Additionally, stirring speeds (240 and 480 rpm) affecting the crystallization of barium sulfate scales were also studied through kinetic analysis. At a certain stirring speed, the precipitation of the barium sulfate scale decreased since its solubility increased with increasing concentrations of Ca and Mg-cations, as indicated by changes in constant rate values. All solid crystals obtained from experiments contained mainly pure barite as validated by X-Ray Diffraction (XRD) method. The SEM micrograph for the morphology of barite showed particles with prismatic and tabular-shaped crystals on the order of 2 to 5 µm particles. The kinetic results provided a general reaction rate equation that can predict barium sulfate deposition in the reservoir for a given brine, supersaturation, and time durations of mixing.
