Abstract

Natural zeolite is a crystalline aluminosilicate mineral that has pores and is often used as a catalyst in the pyrolysis process of plastic waste. Zeolite consists of a three-dimensional framework formed by SiO4 and AlO4 tetrahedrons, creating a distinctive microporous pore network with a large surface area and high adsorption capacity. This study aims to determine the effect of the percentage of natural zeolite catalyst on the combustion rate and oil density of the pyrolysis results of PP-LDPE pure mixture. This study is experimental and the process uses catalytic pyrolysis with natural zeolite catalyst in four different percentages, namely 0% (as a control), 5%, 10%, and 15% of the total mass of plastic input, where each experiment uses 3 kg of plastic as the main material. The study was conducted by heating PP and LDPE samples at a temperature of 250°C in the absence of oxygen for 120 minutes. The results of this study indicate that there is a volume variation in each catalyst mixture, indicating that increasing the pyrolysis catalyst has a positive effect on the amount of liquid fraction produced. A 15% natural zeolite catalyst yielded a maximum yield of 576 ml, equivalent to a 650% increase compared to pyrolysis without a catalyst (0%).

Abstract

Teknologi 3d printing dengan metode Fused Deposition Modeling (FDM) semakin berkembang dalam berbagai sektor industri karena fleksibilitas desain dan efisiensi materialnya. Penelitian ini bertujuan untuk menganalisis pengaruh variasi bed temperature terhadap visual produk, kekuatan bending, dan cacat porositas pada hasil cetakan 3d printing berbahan filament Polylactic Acid (PLA). Spesimen uji bending dibuat mengacu pada standar ASTM D790 dengan variasi bed temperature 30°C, 40°C, 50°C, dan 60°C, serta parameter lainnya dibuat konstan. Pengujian bending dilakukan menggunakan Universal Testing Machine (UTM) HT-2402, sedangkan pengamatan porositas dilakukan menggunakan digital microscope. Hasil penelitian menunjukkan nilai load bending tertinggi diperoleh pada bed temperature 50°C dengan rata-rata 45,20 N, sedangkan nilai terendah pada bed temperature 40°C sebesar 42,37 N. Hasil analisis One Way ANOVA menunjukkan nilai F_hitung sebesar 1,29 dan P-value 0,342 (> 0,05), yang mengindikasikan bahwa variasi bed temperature tidak memberikan pengaruh signifikan terhadap kekuatan bending filament PLA. Pengamatan mikroskopis menunjukkan adanya cacat porositas pada seluruh spesimen dengan jumlah bervariasi antara 1-4 porositas pada setiap variasi suhu. Penelitian ini menyimpulkan bahwa meskipun variasi bed temperature 30°C-60°C tidak berpengaruh signifikan terhadap kekuatan bending, suhu 50°C memberikan performa mekanik terbaik dan seluruh variasi menghasilkan produk dengan tingkat porositas yang bervariasi.

Abstract

The increasing accumulation of polypropylene (PP) plastic waste and durian peel waste has become an environmental concern that requires effective and sustainable management strategies. One promising approach is the conversion of these wastes into liquid fuel through the pyrolysis process. This study aims to investigate the effect of natural zeolite addition on the quality of pyrolysis oil produced from a mixture of PP plastic waste and durian peel powder. The study is based on the principles of pyrolysis, PP plastic depolymerization, the role of biomass in co-pyrolysis, and the function of natural zeolite as a catalyst for hydrocarbon cracking. An experimental laboratory method was employed using a batch-type pyrolysis reactor operated at 400°C for 60 minutes. Natural zeolite concentrations of 5%, 10%, and 15% were applied, while the amount of durian peel powder was maintained at 5 grams for each sample. The parameters analyzed included pyrolysis oil yield, density, viscosity, and calorific value. The results showed that the addition of natural zeolite increased oil production, with the highest yield reaching 375 mL in sample D3. The highest density was obtained in sample D4 at 9.021 g/mL, while the highest viscosity and calorific value were achieved by sample D5 at 0.38 mm²/s and 5,277.01 cal/g, respectively. These findings indicate that natural zeolite significantly influences the characteristics of pyrolysis oil, with a 15% zeolite concentration providing the best energy quality based on the calorific value obtained

Abstract

The increasing amount of polypropylene (PP) plastic waste has become an environmental challenge that requires effective management. One promising technology to address this issue is pyrolysis, a thermal decomposition process carried out in the absence of oxygen that converts plastic waste into valuable liquid fuel. This study aimed to analyze the effect of pyrolysis temperature on the yield, calorific value, and density of liquid fuel produced from polypropylene plastic waste. The pyrolysis process was conducted using a batch reactor with a feedstock mass of 1.25 kg for 60 minutes at temperatures of 300°C, 400°C, and 500°C. The calorific value was determined using a Bomb Calorimeter, while the density was measured using the pycnometer method. The results showed that pyrolysis temperature significantly influenced the characteristics of the liquid fuel produced. The highest calorific value was obtained at 300°C, reaching 38,022.85 J/g (9,087.68 cal/g), which decreased to 33,538.23 J/g (8,015.83 cal/g) at 400°C and further declined to the lowest value of 3,798.05 J/g (907.76 cal/g) at 500°C. Meanwhile, the density values obtained at 300°C, 400°C, and 500°C were 1.028 g/mL, 1.011 g/mL, and 1.031 g/mL, respectively. Based on these findings, a pyrolysis temperature of 300°C produced the highest-quality liquid fuel in terms of calorific value, whereas 400°C yielded a density that was closest to the characteristics of commercial liquid fuels

Abstract

The research utilizes three types of oil, namely used cooking oil, candlenut oil, and olive oil, which were selected due to their availability and potential as biodiesel feedstocks. The main issue addressed in this study is the high dependence on fossil fuels and the need for renewable energy sources with sufficient energy content. This research aims to compare the calorific values of biodiesel produced from different vegetable oils to determine their potential as alternative fuels. Biodiesel was produced through a transesterification process using methanol with a methanol-to-oil ratio of 6:1 and 1% KOH catalyst by weight of oil. The calorific value of the biodiesel was measured using a bomb calorimeter. The results show that biodiesel derived from candlenut oil has the highest calorific value of 8037.07 Cal/gram, followed by biodiesel from used cooking oil at 7399.07 Cal/gram, while biodiesel from olive oil has the lowest calorific value of 7295.15 Cal/gram. These results indicate that the type of vegetable oil significantly influences the calorific value of biodiesel. In conclusion, candlenut oil has the greatest potential as a biodiesel feedstock based on its higher energy content compared to used cooking oil and olive oil.

Abstract

Limbah plastik High-Density Polyethylene (HDPE) menjadi permasalahan lingkungan serius akibat sifatnya yang non-biodegradable dan tingkat penggunaannya yang tinggi. Salah satu solusi yang berpotensi diterapkan adalah konversi limbah plastik menjadi bahan bakar cair melalui proses pirolisis. Penelitian ini bertujuan untuk menganalisis pengaruh variasi temperatur pirolisis terhadap karakteristik pembakaran minyak pirolisis HDPE, khususnya laju dan durasi pembakaran. Proses pirolisis dilakukan pada temperatur 250 °C, 350 °C, dan 450 °C dalam kondisi tanpa oksigen. Minyak pirolisis yang dihasilkan kemudian diuji karakteristik pembakarannya melalui pengukuran laju nyala api dan lama waktu pembakaran hingga bahan bakar habis. Hasil penelitian menunjukkan bahwa peningkatan temperatur pirolisis menyebabkan peningkatan durasi pembakaran minyak pirolisis. Minyak hasil pirolisis pada suhu 450 °C memiliki waktu pembakaran terpanjang sebesar 39,21 s, diikuti oleh suhu 350 °C sebesar 36,68 s, dan suhu 250 °C sebesar 32,23 s. Dengan demikian, temperatur pirolisis berpengaruh signifikan terhadap performa pembakaran minyak pirolisis HDPE, serta menegaskan potensi pirolisis sebagai solusi berkelanjutan dalam pengelolaan limbah plastik dan penyediaan bahan bakar alternatif.

Abstract

Limbah plastik bubble wrap berbahan Low-Density Polyethylene (LDPE) merupakan limbah yang sulit terurai dan berpotensi mencemari lingkungan. Pirolisis menjadi salah satu metode yang efektif untuk mengonversi limbah plastik menjadi bahan bakar cair. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan katalis zeolit alam (clinoptilolite) terhadap densitas minyak hasil pirolisis limbah bubble wrap. Proses pirolisis dilakukan pada temperatur 350–400 °C dengan variasi katalis sebesar 0%, 5%, 10%, dan 15%. Produk cair yang dihasilkan kemudian diuji densitasnya menggunakan metode piknometer. Hasil penelitian menunjukkan bahwa penambahan katalis zeolit berpengaruh terhadap nilai densitas minyak pirolisis. Densitas tertinggi diperoleh pada penggunaan katalis 5% sebesar 0,9241 g/ml. Pada variasi katalis 10% densitas menurun, sedangkan pada katalis 15% densitas kembali meningkat. Hasil ini menunjukkan bahwa konsentrasi katalis tidak selalu berbanding lurus dengan peningkatan densitas minyak. Secara keseluruhan, katalis zeolit 5% merupakan kondisi optimal dalam penelitian ini.

Abstract

This study aims to analyze the effect of variations in the composition of raw materials of Polypropylene (PP) and Polyethylene Terephthalate (PET) plastic waste on the characteristics of pyrolysis oil. The pyrolysis process was carried out using a batch-type reactor with a capacity of 2 kg at a constant temperature of 400°C with a residence time of 60 minutes, using variations of pure PP, pure PET, a mixture of 75% PP + 25% PET, and a mixture of 75% PET + 25% PP. The test results showed that the addition of PET fractions was linear with an increase in oil density values, where the highest density was obtained in pure PET at 0.994 g/mL and the lowest in pure PP at 0.964 g/mL. In contrast, the energetic performance and quantity of liquid products were dominated by the PP fraction; Pure PP oil produced the highest calorific value of 10,535.76 Cal/gram with a maximum liquid volume of 390 ml (yield 0.33%), while a mixture of 75% PET + 25% PP produced the lowest calorific value (8,266.82 Cal/gram) and the smallest oil volume of 280 ml (yield 0.29%). Therefore, the use of pure PP raw materials or a mixture dominated by PP is far superior and effective for producing alternative fuels with abundant quantities and high energy quality.
