“…By extracting cotton lint, oil is produced from seeds. 63 Cottonseed can produce biodiesel in the range of 75% to 80%, having a calorific value of 33 to 39 MJ/kg and kinematic viscosity of 6.9 to 7.5 m 2 /s at 40 C comparable to standard diesel fuel. Another advantage of cottonseed is its ability to thrive on poor soils and aid Malaysia in achieving a sustainable energy supply while reducing environmental carbon pollution.…”

In this study, the performance and exhaust emissions of a direct injection (DI) diesel engine are compared using blended fuels consisting of cottonseed oil (CSO) and ethyl oleate (EO) at various diesel proportions. The uniqueness of this work lies in the fact that it utilizes engine emission and performance studies with blended fuel made from CSO and EO at a higher volume (%) composition than is typically used. Biodiesel reduces brake‐specific fuel consumption (BSFC) compared to CSO, even though it is higher than diesel due to viscosity and heating value. The brake thermal efficiency (BTE) was enhanced until 800 rpm and afterward reduced as the engine's speed continued to increase. Among all the blends, BTE was recorded as highest for CE20D and minimum for CSO. Because EO was unsaturated, culminating in a reasonably short ignition delay, NOx emissions in fused biofuel were marginally more significant than in diesel. The concentrations of UHC and CO reduced as the concentrations of CSO and EO increased, caused by a rise in the oxygen concentration by mass portion. The results of the combustion and emission tests suggest that CE20D has the potential to be a sustainable alternative fuel.

“…Untuk mencapai zero emission dan mengatasi masalah ketergantungan energi fosil, diperkirakan tahun 2030 total produksi energi hijau akan meningkat tiga kali lipat (Zhao et al, 2022). Salah satu energi terbarukan juga ramah lingkungan yang dihasilkan dari teknologi tepat guna serta mudah aplikasinya adalah bioethanol (Roy and Abedin, 2022). Bioethanol merupakan hasil fermentasi dari biomassa yang sangat melimpah (Joseph et al, 2023).…”

Bioethanol merupakan salah satu sumber energi alternatif yang ramah lingkungan untuk mewujudkan global zero emission. Proses produksi bioethanol juga tergolong sangat sederhana melalui proses fermentasi anaerob dari biomassa yang sangat melimpah. Pemanfaatan bahan baku yang terintegrasi mampu mengatasi permasalahan limbah dan meningkatkan nilai ekonomis dari limbah tersebut. Limbah nanas yang berpotensi sebagai rujukan bahan baku bioethanol memiliki kandungan lignin yang akan menghambat hidrolisis bahan organic menjadi bioethanol. Maka dari itu perlu dilakukan suatu usaha untuk menghilangkan kandungan lignin dalam limbah nanas melalui pretreatment gelombang mikro (microwave). Dalam penelitian ini digunakan beberapa variabel proses yaitu: rasio 1:20 (b/v), waktu kontak 10 menit, dan variabel suhu 70, 80 dan 90 o C. Dari hasil analisa dengan menggunakan metode Chesson-Data didapatkan hasil yang menujukan bahwa pengaruh pretreatment microwave cukup signifikan dengan kondisi optimum operasi pada suhu 90 o C dengan hasil lignin yang terlarutkan sebanyak 9,05%, Hal tersebut juga berimbas positif terhadap selulosa yang terlarut sebanyak 29,42% jauh lebih banyak dibandingkan tanpa pretreatmant. Analisa dilanjutkan dengan menggunakan FTIR (Fourier Transformed Infrared Spectroscopy) yang menunjukkan penurunan wave number yang mengidentifikasikan pengaruh pretreatment microwave terhadap struktur lignin yang terdapat pada limbah nanas. Daerah tersebut berada pada panjang gelombang yang cukup tinggi antara (2800 -3500 cm-1) dan panjang gelombang relative cukup rendah yaitu (800 -1700 cm-1) yang keduanya merupakan daerah serapan selulosa.

“…Due to fewer air pollutants and greenhouse gas emissions than traditional petro-diesel, biodiesel is environmentally benign, renewable, biodegradable, and non-toxic. It can be made from animal fats and oils, edible vegetable oil, and non-edible vegetable oil [5,6]. Because it conflicts with food, edible vegetable oil is not advised as a feedstock for biodiesel manufacturing, especially in developing nations.…”

This work created, characterized, and used a magnetic biochar catalyst that is both eco-friendly and very effective. Sugarcane bagasse was selected as primary raw material for catalyst preparation, because it is renewable and ecofriendly biomass. Catalyst created by doping sugarcane bagasse biochar with magnetic material in the form of (FeSO4·7H2O). Thermogravimetric Analysis (TGA) and Fourier Transform Infrared spectroscopy (FTIR) were used to characterize the catalyst. In addition, physical and textural characteristics of the catalyst were identified and interpreted. The characterization outcome showed that the catalyst has good catalytic qualities. For the manufacturing of biodiesel, discarded cooking oil served as the primary feedstock. The experiment was created utilizing the Box–Behnken Design (BBD) technique. There are four variables with the following three levels each: temperature, methanol to oil ratio, catalyst concentration, and reaction time. 29 experiments in total were carried out. Using the RSM function, optimization was done. The optimal conditions for obtaining biodiesel yield—temperature, methanol to oil ratio, reaction time, and catalyst weight—were 43.597 °C, 9.975 mol/L, 49.945 min, and 1.758 wt%. A study of the produced biodiesel using a FTIR showed that the conventional biodiesel IR spectra were confirmed. All physiochemical characteristics found suggested the biodiesel complied with ASTM and EN norms. Overall, the synthesized catalyst had conducted simultaneous reactions in a single batch reactor and had demonstrated suitability for converting used cooking oil to biodiesel.
