The availability of energy from fossil fuels is gradually decreasing. Bioethanol is one of the biofuels which is an alternative energy that can be used as a substitute for petroleum. In Indonesia, in general, the manufacture of bioethanol uses raw materials that compete with foods such as cassava, sugar, and tubers. however, in this research the raw material used is derived from lignocellulosic biomass from pineapple peel. Therefore, this research aims to utilize pineapple peel which is its waste as raw material for making bioethanol through a fermentation process. The fermentation process uses yeast mass and fermentation time as variables where the yeast mass used is 20, 25 and 30 g. while for the fermentation time for 5 and 9 days. In the distillation process, the operating conditions are 78.4 °C for low pressure temperature, and the next step is to analyze the bioethanol produced. Based on the research that has been done, the highest bioethanol content was obtained at 70% with the addition of 25 g of Saccharomyces cerevisiae with a fermentation time of 9 days. From these operating conditions, obtained bioethanol with a concentration of 70%, with a density of 0.8438 gr/mL, and a refractometric index of 9.581.

“…The increase in pineapple fruit production will produce more pineapple skin waste. One pineapple produces leather waste in the range of 34.61% by weight [12]. Therefore, the utilization of pineapple peel waste into useful products such as bioethanol has a good impact in cleaning the environment from waste.…”

The problem of paraffin wax deposition is one of the problems that occurs in the oil industry which causes blockages during the oil production process. To prevent this problem, you can use a chemical method is injecting wax inhibitors. one of the effective wax inhibitors is solvent. So this paper aims to produce bioethanol solvent through biomass engineering, namely pineapple skin waste. For the production of bioethanol through several methods, namely pretreatment, hydrolysis which aims to convert cellulose into glucose with HCl acid, fermentation which aims to convert glucose into bioethanol with the help of saccaromyces cerevisiae yeast and finally distillation. The result in the hydrolysis process with concentrations of HCl 1M, 2M, 3M, 4M and 5M produces glucose 7 Brix, 16 Brix, 20 Brix, 21 Brix and 24 Brix. And with variations in heating time of 1 hour to 5 hours, the optimum glucose was obtained at 3 hours of 24 Brix. The results of fermentation with a variation of 1 day to 6 days, the optimum bioethanol content in fermentation for 3 days is 18%. 18% bioethanol is mixed into waxy crude oil with a pour point value of 43°C, and the result is able to reduce the pour point is 3°C. To increase the decrease in the pour point of bioethanol, it is blend with a toluene, and the result is to reduce the pour point value by 8°C. So it can be concluded that mixing bioethanol and toluene as a solvent can inhibit paraffin wax deposition

Abstract. One type of fruit that is widely cultivated in Indonesia is pineapple. Pineapple fruit that is produced produces a high enough waste, and if it is not used it will cause an unpleasant odor due to the process of decay. Pineapple peel is one of the agricultural wastes that can produce bioethanol because it contains carbohydrates such as reducing sugars. The presence of high carbohydrate and sugar content is converted into bioethanol through a fermentation process with the help of microorganisms. The purpose of this study was to determine how the mechanism of making bioethanol from pineapple peels, to find out what factors influence the levels of bioethanol produced from pineapple peel fermentation, and to find out what the optimal conditions are to obtain the highest levels of bioethanol from pineapple peels.This study uses a systematic literature review method with stages, namely library research, screening based on inclusion and exclusion criteria and data extraction from 6 journals. The results of this study indicate that the mechanism for making bioethanol starts from the process of hydrolysis, fermentation, then distillation. The factors that influence the fermentation process are the type and number of microbes used, length of fermentation time, pH, additives, and temperature. Among the six journals, the highest bioethanol content obtained was 38%, using Saccharomyces cerevisiae mobilized in alginate granules with a fermentation time of 4 days, and 14 grams of yeast used. Abstrak. Salah satu jenis buah-buahan yang banyak dibudidayakan di Indonesia yaitu buah nanas. Buah nanas yang diproduksi menghasilkan limbah yang cukup tinggi, dan jika tidak dimanfaatkan maka akan menimbulkan bau yang tidak sedap karena terjadi proses pembusukan. Kulit nanas merupakan salah satu limbah pertanian yang dapat menghasilkan bioetanol karena mengandung karbohidrat seperti gula reduksi. Adanya kandungan karbohidrat dan gula yang cukup tinggi diubah menjadi bioetanol melalui proses fermentasi dengan bantuan mikroorganisme. Tujuan dari penelitian ini untuk mengetahui bagaimana mekanisme pembuatan bioetanol daari kulit nanas, untuk mengetahui apa saja faktor yang mempengaruhi kadar bioetanol yang dihasilkan dari fermentasi kulit nanas, serta untuk mengetahui bagaimana kondisi optimal untuk memperoleh bioetanol dengan kadar tertinggi dari kulit nanas. Penelitian ini menggunakan metode kajian pustaka sistematis dengan tahapan yaitu penelusuran pustaka, penyaringan berdasarkan kriteria inklusi dan eksklusi serta ekstraksi data dari 6 jurnal. Hasil penelitian ini menunjukkan bahwa mekanisme pembuatan bioetanol dimulai dari proses hidrolisis, fermentasi, kemudian destilasi.Faktor-faktor yang mempengaruhi proses fermentasi adalah jenis dan jumlah mikroba yang digunakan, lamanya waktu fermentasi, pH, zat tambahan, dan suhu. Diantara keenam jurnal kadar bioetanol tertinggi yang diperoleh yaitu sebesar 38%, menggunakan Saccharomyces cerevisiae termobilisasi dalam butiran alginat dengan waktu fermentasi selama 4 hari, dan khamir yang digunakan sebnayak 14 gram.
