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

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.

Abstract

In this study, we report biodiesel production from waste cooking oil using CaO catalyst derived from Madura limestone through a transesterification reaction. Many limestone quarries in Madura can be used as heterogeneous catalysts because they are cheap, easy to separate, and have high basicity. Conversion of limestone into CaO catalyst through calcination at 900°C for 3 hours. The CaO catalyst formed was characterized using X-Ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX) instruments. Biodiesel formed through the transesterification reaction was analyzed using GC-MS. Furthermore, biodiesel blends from waste cooking oil and pure diesel were prepared in volume percentages (B-10, B-20, B-30, B-40, and B-100) for testing on diesel engine performance. The results of testing the highest torque and brake horsepower (BHP) were obtained on pure diesel fuel (S-100) at 2.49 Nm and 381.12 watts, respectively. The lowest fuel consumption at 1500 rpm is produced on the B-20 at 0.186 kg/h. Overall, the emission characteristics of carbon monoxide (CO), nitrogen oxides (NOx), and nitrogen monoxide (NO) with the lowest concentration resulted from biodiesel blends rather than pure diesel.

Abstract

Data BAPPEDA Jawa Timur pada bulan Februari 2023 menunjukkan bahwa permasalahan pengangguran pada lulusan SMA/SMK adalah yang tertinggi, sehingga perlu pembekalan agar para siswa bisa menciptakan lapangan pekerjaan sendiri. Jurusan Teknologi Kemaritiman di Politeknik Negeri Madura turut mempunyai tanggung jawab dalam memberikan pembekalan pada siswa SMA khususnya di Pamekasan untuk bisa mempunyai pengetahuan dalam bidang kewirausahaan dengan memberikan pelatihan pembuatan miniatur kapal sebagai lahan berwirausaha dalam penjualan cinderamata atau kesenian. Pelatihan pembuatan miniatur kapal dilaksanakan dengan total peserta 47 siswa dari 2 (dua) sekolah di Pamekasan yaitu SMAN 3 dan 4 Pamekasan. Pelaksanaan pelatihan pembuatan miniatur kapal diawali dengan koordinasi internal dan eksternal, pembuatan modul pelatihan. Pada hari pertama pelatihan diawali dengan pelaksanaan pre-test, penyampaian materi tentang kewirausahaan, e-commerce, dan miniatur kapal serta ditutup dengan post-test. Pada hari kedua pelatihan fokus kepada cara pembuatan miniatur kapal sebagai produk yang akan dijadikan dijual. Berdasarkan hasil pre-test dan post-test dapat diketahui bahwa siswa dan siswi di SMAN 3 dan 4 mengalami peningkatan secara pemahaman terhadap kewirausahaan, e-commerce, dan pembuatan miniatur kapal.

Abstract

Madura Island is part of the province of East Java which has a lot of potential, starting from tourism, natural resource potential, such as oil, natural gas, and salt, as well as cultural potential. Until now, the large potential possessed by the island of Madura has not been managed optimally; this is partly due to the low interest of the Madurese people in studying as much as possible. Welding and inspection training for SMAN 3 Sampang students as an effort to strengthen the Human Development Index (HDI) in the sector of improving the quality of human resources is one of the efforts that will be taken by the Maritime Technology Department of the Madura State Polytechnic to be able to improve the quality of high school graduates. Hence, they are ready to compete in the world of work. Overall, the training resulted in a good understanding for participants, as evidenced by the improvement in post-test results. The training participant satisfaction questionnaire showed poor and poor results for several aspects of resource persons, training materials, and consumption.
