Abstract

Alat penukar panas merupakan salah satu alat yang digunakan sebagai perpindahan panas antara dua fluida yang memiliki temperatur yang berbeda. Alat penukar panas memiliki tipe dan desain struktur yang berbeda, salah satu alat yang digunakan yaitu Plate and Frame Heat Exchanger (PFHE). Tujuan penelitian PFHE ini adalah untuk mengetahui pengaruh kenaikan temperatur fluida panas masuk dengan perbedaan arah aliran fluida terhadap efektivitas penukar panas NTU (ɛ-NTU). Penelitian ini dilakukan pada temperatur fluida panas 39-52°C pada arah aliran searah dan arah aliran berlawanan arah. Fluida panas dan fluida dingin yang digunakan pada penelitian ini yaitu air karena proses perpindahan panas yang baik dan tidak berbahaya. Dari penelitian ini disimpulkan bahwa meningkatnya temperatur fluida panas masuk diperoleh kenaikan efektivitas penukar panas NTU (ɛ-NTU) pada arah aliran searah maupun pada arah aliran berlawanan arah. Nilai ɛ-NTU pada arah aliran berlawanan arah adalah 31,97-38,80% dan nilai ɛ- NTU pada arah aliran searah adalah 24,13-27,95%. Nilai ɛ-NTU pada arah aliran berlawanan arah lebih besar dari pada arah aliran searah. Ini menunjukan bahwa arah aliran berlawanan arah lebih efektif melakukan proses perpindahan panas dari pada arah aliran searah.

Abstract

Coconut sap produced from coconut trees has a short shelf life due to contamination and undergoes natural fermentation. One way to extend the shelf life of coconut sap is by adding preservatives. This research aims to determine the effect of adding natural preservative extracts on the antioxidant value, pH, sugar, and alcohol content of coconut sap by adding natural preservatives. There are five samples: pure sap (NM); sap with sugar lime (NK); sap with sugar lime and cinnamon extract (NKM); sap with sugar lime and mango leaf extract (NDM); sap with sugar lime and noni leaf extract (NKD). The study was conducted by extracting natural preservatives, namely cinnamon extract, mango leaves extract, and noni leaves extract, using the maceration method. These natural preservative extracts were mixed with Ca(OH)2 in a 1:1 ratio and dissolved in distilled water. The mixture was then mixed with the sap. The results of the antioxidant test showed that the IC50 values of the NM, NK, NKM, NDM, and NKD samples were 52.911, 144.409, 26.043, 49.275, and 24.21 ppm, respectively. The highest pH value was found in the NK sample at 13.8, and the lowest in the NM sample at 3.8. The lowest sugar content was in the NM and NDK samples, with 10.6 and 14.6%. The highest alcohol content was found in the NK and NKD samples, with alcohol contents of 14.80% and 14.20%. This study shows that adding natural preservatives such as cinnamon, mango leaves, and noni leaves can increase the antioxidant activity of coconut sap, raise its pH, and maintain its sugar content to prevent it from being reduced to alcohol.

Abstract

Textile wastewater pollution, mainly containing azo dyes such as Remazol Red, presents an environmental challenge in developing countries, including Indonesia. Although various wastewater treatment methods have been extensively studied, biological treatment efficiency at high dye concentrations remains challenging. In this context, aerobic granular sludge (AGS) technology in sequencing batch reactors (SBR) offers a potential solution. However, the existing knowledge gap lies in optimizing operating conditions for optimal dye degradation. This study demonstrates the use of response surface methodology (RSM) with a Box-Behnken design (BBD) to model the effects of independent variables such as aeration time, dye concentration, and COD on decolorization efficiency. Experimental results show that increasing aeration time and COD concentration significantly improve dye degradation, with an optimal decolorization value of 77% achieved at a COD concentration of 1000 mg/L and an aeration time of 24 hours. These findings imply that AGS-SBR technology can be further optimized for effective textile wastewater treatment on various industrial scales.

Abstract

Rubber seeds contain fatty acids that can be used as industrial mixtures and processed into biodiesel, soap production, and animal feed. So far, the utilization of rubber seeds has not been optimal, so rubber seeds can be processed into oil using an ultrasound-assisted extraction (UAE). The study aimed to determine the characteristics of oil from rubber seed extract, such as color, odor, and chemical compound content. In addition, the study seeks to assess the effect of solvent type (n-hexane, ethyl acetate, and ethanol), extraction time (30, 45, and 60 minutes), and ratio of material :solvent (1:5, 1:6, and 1:7 w/v) on the yield (%) of oil extract from rubber seeds. The results showed that oil from rubber seed extract obtained with n-hexane exhibited a yellow color and had a rubber seed aroma, ethyl acetate solvent produced a cloudy yellow color and had an ethyl acetate aroma, and ethanol solvent produced a brownish yellow color and had a rubber seed aroma. The most significant oil extraction result from rubber seeds is ethanol solvent with a time of 45 and 60 minutes, and a ratio of material to solvent of 1:7 w/v. The rubber seed oil content was tested using GC-MS taken from the three best samples of each type of solvent (n-hexane, ethyl acetate, and ethanol) at an extraction time of 45 minutes and a ratio of material to solvent of 1:7 w/v. The oil compound content in rubber seed extract was 90.64% using hexane, 35.95% using ethyl acetate, and 25.19% using ethanol as solvents. The oil compounds extracted using n-hexane solvent consisted of 9-octadecanoic acid, methyl ester at 63.917%, those using ethyl acetate solvent were acetic acid, butyl ester at 30.67%, and those using ethanol solvent were n-hexadecanoic acid at 9.15%.
