Abstract

Sedimentation at the mouth of the Palu River is the cause of frequent flooding in Palu City. This study aims to understand the hydrodynamic conditions and longshore sediment transport around the mouth of the Palu River. Hydrodynamic conditions were analyzed by measuring velocity and current direction, salinity, discharge, breaking wave height, breaking wave depth, wave incidence angle, water density, and water depth. While the amount of longshore sediment transport was calculated based on the CERC empirical formula. The results revealed that the distribution of currents at the mouth of the Palu River was dominated by river currents, where the amount of seawater in the mouth of the river was small. This could be seen from the small salinity value, which ranged from 1 ‰ to 5 ‰. The longshore sediment transport around the Palu River estuary is 36.06 m3/day, where this sediment resulted in silting at the Palu River estuary during deposition.

Abstract

The physical properties of plastic waste that is not easily biodegradable is a serious problem in pollution on land and at sea. Therefore, technology to be able to solve these problems needs to be developed. This study aims to understand at what temperature plastic waste can produce fuel oil. The type of waste used in this research is polyethylene terephthalate (PET), which is a type of plastic that uses drink bottles. The design of the device to convert plastic into fuel oil in this study consisted of 3 components, namely a valve which functions to regulate the flow of steam from the reactor tube to the condensate tube, the temperature gauge functions to measure the temperature contained in the reactor tube, and the heat blanket functions as a coating, this can reduce excessive heat in the reactor tube. The results revealed that at a temperature of 100ºC to 150ºC with a variation of time (26.3, 27.3, and 28) minutes did not produce oil. At a temperature of 200ºC to 250ºC with time variations (33, 34, and 35) minutes, the condensate tube begins to produce fuel above the water surface.

Abstract

Knowledge of explosion thresholds is essential to ensure a safe area. Fire or explosion may occur spontaneously if conditions in the area exceed the limits. Low explosive limit (LEL) measurements for 31 days have been carried out at Korpri Housing, precisely at Jl. Wilis Mukti 1, RT. 26, Kelurahan Sepinggan, Kecamatan Balikpapan Selatan, Balikpapan City, East Kalimantan. Measurements were conducted using a multimeter gas detector (compound gas monitor WT8811) for 31 days at three points, namely the first point was located about 5 m from the gas source, the second point was located at the gas source, and the third point was located around 20-25 m from the gas source. The measurement results revealed that the highest LEL value was at the second point with an average value of 4.79% LEL. The highest measurement results occurred on April 6, 2021 with measurement results in the morning at 09.00 WITA 14.8% LEL, afternoon at 12.00 WITA 13.8% LEL, and at 15.00 WITA 11.6% LEL.

Abstract

Biodiesel merupakan bahan bakar alternatif pengganti solar yang berasal dari bahan nabati seperti minyak goreng bekas. Minyak goreng bekas adalah limbah dari sisa penggorengan, biasanya dibuang karena sudah digunakan lebih dari satu kali. Transesterifikasi merupakan reaksi antara trigliserida yang terkandung dalam minyak nabati atau lemak hewan dengan alkohol untuk membentuk alkil ester. Penelitian ini bertujuan untuk menganalisis sifat fisika dan nilai keekonomian minyak goreng bekas menjadi biodiesel dengan metode transesterifikasi. Bahan limbah yang digunakan merupakan minyak goreng. Analisis fisika dilakukan dengan melakukan pengujian karakteristik biodiesel meliputi % FFA, angka asam, gliserol, kandungan air, massa jenis, pH, rendemen dan warna. Nilai karakteristik biodisel pada sampel 1 yaitu: FFA sebesar 0,65 %, angka asam 0,42 mg, gliserol 59 mL, kadar air 0,006 %, rendemen 0,83 %, massa jenis 852 kg/m3, pH 7 dan menghasilkan warna kuning emas, sedangkan nilai karakteristik biodisel pada sampel 2 yaitu: FFA sebesar 0,56 %, angka asam 0,50 mg, gliserol 58 mL, kadar air 0 %, rendemen 0,83 %, massa jenis 845 kg/m3, pH 7 dan menghasilkan warna kuning emas. Nilai karakteristik biodisel pada sampel 3 yaitu: FFA sebesar 0,65 %, angka asam 0,50 mg, gliserol 59 mL, kadar air 0,07 %, rendemen 0,78 %, massa jenis 847 kg/m3, pH 7 dan menghasilkan warna kuning emas. Pengolahan minyak goreng bekas sebanyak 300 L/bulan akan menghasilkan biodiesel 246 L/bulan @Rp. 9.000 = Rp. 2.214.000 dan gliserol 23 L/bulan @Rp. 3.000 = Rp. 86.250. Sehingga diperoleh total pendapatan = Rp.2.300.250/bulan. Sementara itu, biaya produksi berupa penggunaan listrik, pembelian pelarut dan katalis sebesar Rp.1.370.500/bulan. Sehingga Hasil analisis keekonomian menunjukkan bahwa pembuatan biodiesel skala industri kecil layak diproduksi dengan nilai keuntungan mencapai Rp.929.750/bulan.
