In this study, the use of biodiesel from nyamplung oil (Calophyllum Inophyllum) was studied through a transesterification reaction using a heterogeneous catalyst of CaO from limestone originating from Pamekasan, Madura. The composition ratio used between nyamplung oil and methanol in the transesterification reaction was 1:12 (mol/mol) with the addition of 4% CaO catalyst. The biodiesel that is formed is then tested for its performance and emission characteristics in diesel engines with various fuel mixtures between pure diesel and biodiesel (B-10, B-20, B-30, B-40, B-100 and S-100). The test results for biodiesel blends with the highest power produced from B-10, B-20, B-30 and B-100 fuels were 0.26 kW each at a load of 250 watts. While at a load of 500 watts, the highest power is obtained from the B-40 fuel, which is 0.58 kW. The results of performance testing using S-100 fuel obtained the highest power values ​​of 0.27 and 0.58 kW, respectively, with a load of 250 and 500 watts. Performance testing for biodiesel blends, the highest torque value was obtained when using B-10, B-20, B-30 and B-100 fuels, which were 1.65 N.m each with a load of 250 watts. While at a load of 500 watts, the highest torque is obtained on B-40 fuel, which is 3.69 N.m. The fuel S-100 produces torque of 1.71 and 3.69 N.m, respectively, with a load of 250 and 500 watts. Emission gases characteristics of carbon monoxide (CO), nitrogen monoxide (NO) and nitrogen oxides (NOx) showed the lowest concentrations obtained in B-100 fuel were 387 ppm, 92 ppm and 96 ppm, respectively.

Despite possessing non-renewable properties, fossil fuel is still widely used as a major energy source. Subsequently, the fossil fuel demand has been increasing while the supply is depleting over time leading to an energy crisis. Fossil fuel also causes associated environmental problems such as emissions as the primary driver of global warming and climate change. Thereby, the development of alternative fuels, such as bioethanol, is beneficial to combat the fossil fuel challenges. Bioethanol is a promising fuel owing to its renewable and environmentally friendly characteristics. In this study, bioethanol was synthesized by a fermentation process over yeast (Saccharomyces Cerevisiae). The feedstock for this process is an abundant resource namely black sticky rice. Bioethanol resulting from this process was mixed with gasoline and applied to a motorcycle machine. The performance of bioethanol was defined by power, torque, and emission. The proportion of the mixture was varied with bioethanol content of 0%, 10 %, 20 %, 30 %, and 40%. The mixture of bioethanol-gasoline produced higher power and torque value compared to gasoline. The E40 mixture had the highest power and torque value with 8.5 hp and 9.2 Nm respectively. However, the combustion of bioethanol-gasoline resulted in more CO2 emission, while the emissions of O2, NO, and NOx were lower. The lowest NOx emissions content was obtained at E30 and E40 blends, about 7 ppm. Meanwhile, the lowest NO emission content was obtained at E30 and E40 blends, about 6 ppm.

The piping system design due to pressure will experience vibrations due to the excitation force that comes from the pump. Excitation force occurs due to changes in fluid flow velocity. In addition, the length of the pipe and the large number of bends of the pipe due to cross with other installations, cause vibrations in the pipe. vibration analysis in the pipe should not be underestimated, where it is necessary to identify the causes of vibration in the pipe due to flow and placement of good support and the effect of obstacles in the pipe flow to prevent failure of the pipe. In addition, clogging of pipelines can result in reduced system carrying capacity, wastage of energy and resources, and the potential for increased likelihood of environmental and health problems. Therefore, this study will discuss the identification of blockage of water flow in pipes using the vibration method. The excitation force comes from the fluid flow flowing in the pipe, while the vibration response is generated using the accelerometer sensor provided with the FFT Analyzer. Retrieval of data using the accelerometer as a vibration sensor served by Ono Sokki's FFT analyzer which is then analyzed using Matlab. Installation with four supports shows that the resonance that occurs in the installation of two supports can be reduced, but it causes the magnitude of the iron pipe to increase, while the PVC pipe decreases at a frequency of 5 Hz. In general, the result of installing four supports shows that the noise on the PVC pipe is reduced while the iron pipe is getting higher due to the installation of a barrier in the pipe due to water flow. The vibration pattern that occurs uses a harmonic response simulation, the vibration pattern that occurs uses a harmonic response simulation.

Kaolin with alumina and silica content is used as the main material in this research to study the synthesis of ZSM-5 zeolite. The hydrothermal process was carried out through different aging times, namely 12, 24 and 36 hours. Tetrapropyl ammonium bromide (TPABr) was used as a template for the Mobile Five-1 (MFI) structure guide. X-ray diffraction (XRD) and infrared spectroscopy (FTIR) instruments were used to characterize the ZSM-5 zeolite formed from the synthesis results. This was done to identify the phase change from kaolin to zeolite ZSM-5. The results of the analysis using XRD for all samples showed a characteristic peak of the ZSM-5 zeolite at 2θ around 7.88°; 8.72° ;23.09°; 23.84° and 24.32°. However, samples with an aging time of 12 hours also showed peaks at 2θ around 15.84° and 26.03° which indicated an analsim phase. The absorption bands from the FTIR characterization for all samples are seen at wave numbers around 453, 542, 793, 1088 and 1221 cm−1 which are the characteristic peak points of ZSM-5 zeolite. The longer the aging time indicates that the crystallinity of the ZSM-5 zeolite is increasing. The highest crystallinity was obtained from ZSM-5 zeolite samples which were aged for 36 hours. This indicates an increasing number of ZSM-5 crystal nuclei with high purity because there is no other phase besides the ZSM-5 phase.

Gasoline engines should sound soft, even tend to be minimal. But when the symptom of a rough sound emerged from the engine room, it was even more like a diesel sound that was quite loud. So that many customers have complained about the rough sound of their vehicle's engine when the engine is started, from the results of the initial inspection that was carried out as a result of the rough noise coming from the bearings on the alternator which experienced wear due to reduced lubrication in the bearings. This requires that preventive maintenance checks on the alternator are a must in the automotive world. On the basis of the above, in this paper, we will discuss the damage to the Daihatsu Luxio alternator with the frequency response function (FRF) method. Damage to the alternator can be seen at point A and point D, seen with a frequency at 1500 Hz in a damaged condition, while in good condition there is no frequency at 1500 Hz. At points B, C, E, and F have the same vibration pattern between the damaged and undamaged conditions. Visually checking results show that the bearing component at point A, it is known that the ball bearing is peeling. This results in a rough spinning of the bearing and makes the alternator make a rough noise while working.

This study aims to analyze the effect of the movement of macroeconomic variables on financing using the musharaka contract on Islamic banks. This study consists of sharia commercial banks and sharia business units using monthly data from January 2004 to December 2019. This study uses Vector Error Correction Model (VECM) to answer the research objectives. All variables tested have an influence on financing using the musharaka contract. Financing using the musharaka contract responds negatively to movements in the exchange rate and interest rates while inflation responds positively and negatively. Islamic banking needs to prepare more reserve funds in the face of such movements before achieving stability. The musharaka contract financing itself dominates the forecasting then followed by interest rates, inflation, and exchange rates. Therefore, Islamic banking needs to prepare a reserve fund in the face of these shocks before achieving stability.

This paper examines the Concept of Income Distribution in Islam through the Zakat Fund which is managed as a source of funds in improving better conditions in the socio-economic poor population in the fields of education, housing, and income to support the economic growth of West Java Province. This study uses a sample test through a quantitative method and real data to observe the correlation and potential contribution of zakat from Muslim residents who work in West Java region to the distribution of income of the poor population. For each observation variable, before-and-after regression and comparison tests are associated with the potential of zakat as a concept of the distribution of Sharia or Islamic income. Hypothesis testing of two means is used to obtain different observational results from the results of this study. There is significant diversity in the socio-economic conditions of the poor before and after the implementation of the concept of distribution of Sharia or Islamic income in West Java Province. Likewise, the hypothesis testing shows that Sharia or Islamic income distribution has a significant influence on socio-economic conditions in the fields of education, proper housing, and income of the poor population on the growth of the regional economy of West Java (GRDP). With the diversity of relationships and influences among socioeconomic variables, e.g. the income of poor people after the calculation of Zakat and improper housing with the distribution of income with the concept of Islam have opposite relationships. However, the unidirectional relationship occurs in the education on theeconomic growth of the West Java regional domestic.

Cenderawasih Bay has extremely high biodiversity with an enormous amount of endemic species due to geography isolation. Tripneustes gratilla is one of the species that is abundant in the bay. The species has ecological value that is suitable for bio-indicators of the environmental condition. Since the Bay relatively isolated area, then we examined the impact of the geographical conditions on genetic diversity and connectivity of Tripneustes gratilla among populations in the region surrounding Cenderawasih Bay based on the mitochondrial cytochrome c-oxidase-1 gene. Results of the study showed that genetic variation of the species within the population is high; despite the genetic variation among populations was low. The data suggested that the entire population of T. gratilla were closed connected, homogeneous, and shared polymorphic profile. Then we assumed the gene flow occurred for a long time among populations without geographical barriers. This information is a warrant to develop an effective strategy to maintain biodiversity in the Cenderawasih Bay.
