Abstract

This study successfully improved the performance of oxidative desulfurization method to reduce sulfur content from residue oil (condensate) with modifications of oxidation and extraction steps which was repeated for several stages. Residue oil used in this study contain 386.2 ppm of initial sulfur content. In oxidation process, H2O2 as oxidizer and acid as catalyst were used within temperature range of 30–60 °C and time interval from 30 to 120 min. In extraction process, various alcohol solvents (methanol, ethanol, and propanol) were used with the temperature of 30 °C in 30 min for every residue oil ratio to solvent (v/v). The best reducing sulfur result achieved was 35.9 ppm or 90.7% desulfurization. This result was achieved after 4 recursively extractions using ethanol as solvent. This study successfully reduced sulfur content in residue oil to meet the international standard (< 50 ppm).

Abstract

Selain produksi biodiesel, bioetanol, biometana dan biohidrogen dari sumber terbarukan, gamma-valerolactone (GVL) muncul sebagai bahan bakar terbarukan potensial lainnya yang dapat diproduksi dari biomassa. GVL menunjukkan karakteristik yang sesuai sebagai sumber energi cair berkelanjutan yang menjanjikan. Dlaam kegiatan produksi GVL murni jumlah besar pastinya melibatkan proses pemisahan/ pemurnian, salah satunya adalah distilasi. Dalam perancangan proses distilasi diperlukan data kesetimbangan Uap – Cair (VLE), dan untuk akurasi perancangan biasanya digunakakan software simulasi proses seperti ChemCAD. Dalam penelitian ini, data VLE yang tersedia akan direparamterisasi sehingga bisa digunakan sebagai parameter model thermodinamika di Software ChemCAD. Pada penelitian ini dilakukan reparemeterisasi parameter interaksi biner (BIP) model NRTL untuk data VLE komponen yang terlibat dalam produksi GVL dari literature yang tersedia. Kemudian BIP hasil reparemterisasi digunakan untuk analisis sensitivitas pada shortcut kolom distilasi. Hasil analisis sensitivitas menunjukan bahwa perubahan suhu umpan berpengaruh terhadap konvigurasi kolom, tetapi tidak pada kualitas GVL yang dihasilkan In addition to producing biodiesel, bioethanol, biomethane, and biohydrogen from renewable sources, gamma- valerolactone (GVL) is emerging as a potential renewable fuel from biomass. As a promising long-term liquid energy source, GVL possesses the necessary characteristics. The production of pure GVL in large quantities involves a separation/purification process, one of which is distillation. In designing the distillation process, Vapor- Liquid equilibrium(VLE) data is needed, and process simulation software such as ChemCAD is usually used for design accuracy. In this study, the available VLE data will be reparameterized to be used as a thermodynamic model parameter in ChemCAD Software. The binary interaction parameter (BIP) NRTL model reparameterization for the VLE data of the components involved in the creation of GVL was carried out in this work using data from the literature. The reparameterized BIP was then applied to the distillation column shortcut for sensitivity analysis. The findings of the sensitivity study reveal that changing the feed temperature changes the column arrangement but not the quality of the GVL produced

Abstract

Pemisahan n-propil asetat dari campuran terner n-propil asetat/n-propanol/air merupakan salah satu proses yang tidak dapat dilakukan dengan distilasi sederhana. Adanya azeotrop terner minimum dari campuran tersebut menyebabkan n-propil asetat hanya dapat dipisahkan dari campuran n-propanol dan air salah satunya dengan metode distilasi ekstraktif. Distilasi ekstraktif merupakan proses vaporisasi parsial dengan menambahkan suatu agen pemisah non-volatil yang disebut sebagai sovent atau agen ekstraktif. Solvent yang digunakan dalam simulasi proses ini adalah campuran DMSO (Dimetil Sulfoksida) dan Gliserol dengan komposisi 50 % massa dengan perbandingan 1:2 untuk massa umpan kolom : solvent. Feed yang digunakan adalah n-propanol (10 kmol/jam) dan asam asetat (13 kmol/jam) masing-masing pada suhu 25°C dan tekanan 101,3 kPa. Hasil n-propil asetat terbaik diperoleh saat solvent diumpankan pada stage 5 dengan fraksi mol n-propil asetat pada distilat 0,9975 disertai dengan minimumnya energi reboiler yang digunakan pada konfigurasi kolom ini. n-Propyl acetate separation of the n-propyl acetate /n-propanol/water mixture composition can't be done by simple distillation. The existence of minimum ternary azeotrope on the mixture causes n-propyl acetate can be separated only by extractive distillation method. Extractive distillation is a partial vaporization process in the presence of a non-volatile separating agent called as solvent or extractive agent. Solvent used in the simulation process is DMSO (Dimethyl Sulfoxide)-Glycerol mixture (50% mass) with a ratio of 1: 2 for column feed : solvent. n-Propanol (10 kmol/hour) and acetic acid (13 kmol/hour) are fed into reactor (before extractive distillation process) at 25°C and 101.3 kPa, respectively. The best results of n-propyl acetate were obtained when the solvent was fed to stage 5 in which mole fraction of n-propyl acetate in distillate 0.9975 accompanied by the minimum reboiler energy used in this column configuration.

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kemampuan masyarakat, khususnya komunitas pengelola sampah TPAS Manggar, dengan melatih mereka membuat produk biopellet menggunakan mesin pelletizer yang berbasis sistem penggerak roller. Kegiatan pengabdian dilakukan dengan melibatkan 25 peserta dari komunitas pengelola sampah TPAS Maggar. Kegiatan ini mencakup penyampaian materi teori, yang meliputi sosialisasi mengenai sampah padat, pemilahan sampah, dan manajemen pengolahannya. Selain itu, dilakukan demonstrasi penggunaan alat pelletizer, praktik langsung pembuatan biopellet, serta evaluasi melalui pre-test dan post-test. Dengan menggunakan analisis statistik Paired Two Sample for Means, terdapat peningkatan yang signifikan dalam tingkat pengetahuan serta keterampilan anggota kelompok pelatihan. Perbedaan rerata skor pre-test dan post-test yang secara statistik signifikan mengindikasikan bahwa program pelatihan tersebut memiliki dampak yang positif terhadap kemampuan para peserta. Dengan hasil evaluasi ini, pelatihan serupa diharapkan dapat direplikasi di komunitas lain sebagai upaya peningkatan kesadaran lingkungan dan penerapan teknologi ramah lingkungan dalam pengelolaan sampah.Abstract: The Balikpapan Environmental Agency (DLH) has issued a warning that the Manggar Final Waste Processing Site (TPAS) may reach full capacity by 2026 unless more effective waste management strategies are implemented. Although various methods of converting solid waste into fuel have been attempted to address the growing waste volume, these efforts have yet to produce significant results. Consequently, solid waste processing initiatives remain ongoing.In response, a community service program was initiated to enhance the capabilities of local residents, particularly members of the Manggar TPAS waste management team. This initiative focused on training participants in the production of biopellets using a pelletizer machine equipped with a roller drive system. A total of 20 community members took part in this program. The training included the presentation of theoretical material covering topics such as solid waste management, sorting procedures, and waste processing techniques. It also featured hands-on sessions where participants practiced operating the pelletizer and producing biopellets. To assess the program’s effectiveness, participants underwent pre- and post-training evaluations. Using the Paired Two Sample for Means statistical method, the data revealed a significant improvement in the participants’ knowledge and skills. The measurable increase in average test scores demonstrates the positive impact of the training. Based on these findings, it is advisable to implement similar initiatives in other communities to encourage environmental awareness and the use of sustainable waste management technologies.

Abstract

Refuse-Derived Fuel (RDF) is increasingly acknowledged as a sustainable method of managing municipal solid waste while simultaneously producing valuable energy. However, the quality and compactness of RDF as a fuel can vary substantially depending on the materials used to produce it. The incorporation of biomass waste and calcium oxide (CaO) significantly influences the pelletizing behavior of biopellets by altering their physical and thermal properties, which in turn determines their effectiveness and suitability as a fuel source. In this study, representative RDF pellets were prepared by blending four primary components: wood sawdust, organic waste, plastic waste, and a fixed proportion of CaO. The investigation focused on assessing the effects of varying biomass waste-to-organic waste ratios on the physicochemical characteristics, densification behavior, and proximate properties of typical RDF pellets. The experimental design included biomass-to-organic waste ratios of 1:1, 2:1, 3:1, 4:1, 5:1, and 6:1 while the proportions of plastic (20 wt%) and CaO (5 wt%) were held constant. The findings revealed that optimal RDF performance was achieved at biomass-to-organic waste ratios of 1:1 and 6:1, respectively. The resulting RDF pellets exhibited the following properties: ash content of 7.04 ± 8.78%, moisture content of 8.19 ± 8.82%, volatile matter ranging from 65.11 ± 66.19%, fixed carbon content of 13.95 ± 17.32%, calorific values between 4193 ± 4419 kcal·kg-1, and bulk densities of 0.98 ± 1.18 kg·dm-3. These results highlight the potential of RDF pellets as a promising alternative fuel source for boiler applications.
