Abstract

The manufacture of natural fiber composites was carried out to determine whether the composite from a combination of palm fiber and straw fiber was feasible as a substitute for synthetic fiber composites used for electric car bodies at State Polytechnic of Madura. This research was conducted with variations in the ratio of 100% palm fiber, 100% straw fiber, 1: 2, 2: 1 and 1: 1. Testing of composite material alloys was carried out by testing the impact test, tensile test, and testing the material on the cars body prototype. Based on the test results on the composite and prototype, it was known that the 100% variation of palm fiber has the highest modulus of elasticity, which was 499.09 N / mm2, while the 2: 1 variation has the highest toughness value, which was 14.4.10-3J / mm2, and the results of the crash test was carried out to get a speed of 3.84 m / s, the body surface only experienced cracks, without major damage.

Abstract

Lead has been known as one of the heavy metals with a high adverse effect to the environment and human health. This study reports the activity of activated carbon from biomass of banana peel as an adsorbent to resolve the hazardous lead-contaminated wastewater. The influence of the activator was studied via the alteration of NaOH concentration from 1, 3, and 5 M, where the sample was denoted as AC-1, AC-3, and AC-5. Some techniques, including FTIR, XRD, and SEM were applied to characterize the sample with the highest adsorption capacity. FTIR result affirmed the presence of hydroxyl group on the activated carbon with NaOH 1 M (AC-1) that was beneficial for adsorption. XRD and SEM confirmed that the activated carbon possessed crystalline and amorphous phases with sheet-like morphology. Regarding Pb(II) adsorption, the higher concentration of activator caused the decline of adsorption capacity as the contact time prolonged. The highest adsorption capacity and efficiency were obtained using 1 M NaOH activator with a contact time of 1 hour, which was 3.71 mg/gram and 97.86%, respectively.

Abstract

Pemanfaatan batu kapur dari Pamekasan, Madura sebagai katalis heterogen pada reaksi pembuatan biodiesel dipelajari pada penelitian ini.  Batu kapur dikalsinasi pada suhu 900 ºC selama 3 jam untuk membentuk katalis CaO. Katalis CaO yang terbentuk dikarakterisasi menggunakan difraksi sinar-X (XRD), spektroskopi inframerah (FTIR) dan Scanning Electron Microscopy-Energy Dispersive X-Ray Analysis (SEM-EDX). Proses transesterifikasi dari minyak nyamplung dilakukan dengan rasio mol minyak terhadap methanol sebesar 1:16 pada temperatur 60 °C selama 1 jam dengan katalis CaO sebesar 4 % (w/w). Hasil analisis GC-MS diperoleh yield biodiesel sebesar 54% dengan konversi sebesar 49%.

Abstract

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. Meanwhile, the highest concentrations of CO, NO and NOx emissions were produced from pure diesel fuel (S-100), namely 574 ppm, 126 ppm and 132 ppm, respectively.
