Abstract

The COVID-19 pandemic has increased online shopping and food delivery, causing a surge in single-use plastic waste and has become a habit to this day along with the rapid development of digital technology. Dream Central Waste Bank (BSI Dream) in Wijaya Pura Village collects 3 tons of waste monthly but lacked advanced plastic processing technology. This community service initiative aimed to implement a pyrolysis reactor to convert plastic waste into fuel oil and paving blocks, thereby enhancing economic value while promoting environmental sustainability. The activity stages included partner coordination and surveys, reactor performance upgrades, operational training, and evaluation. This activity involved five partners representing the Wijaya Pura Village community.  The reactor successfully produced fuel oil (density: 0.848–0.912 g/mL) and residues suitable for paving block production. The outcome of this initiative demonstrated improved skills among partners, the creation of marketable products and increased community income opportunities. Furthermore, the activity fostered greater awareness of the importance of sustainable waste management and supported the application of circular economy principles.

Abstract

Mendalo Indah Village has great potential for trade because of its strategic location near two major universities in Jambi Province, namely Jambi University and UIN Sultan Thaha Jambi. Students in this area have a strong preference for instant food and beverages as a result of their busy academic and practicum schedules. The urgency of this community service activity lies in the need for instant but natural health supplements among students, as well as the need for housewives to gain additional income. The training on the production of “Japan Instan” in Mendalo Indah Village aims to empower the community, especially housewives and unemployed women, by developing creative economic activities through innovative and marketable prod ucts. Ginger was chosen as the main ingredient because of its well-known health benefits, such as relieving headaches, preventing colds, improving digestion and increasing appetite (stimulant). Ginger is also a commonly found local plant. The training covered the processing of ingredients, packaging and marketing strategies. Additionally, pandan leaves were utilized as an innovation to enhance the flavor and aroma, resulting in a healthy instant beverage product

Abstract

Hydrotalcite (HT) is a type of clay mineral belonging to the group of layered double hydroxides (LDHs) or anionic clays, which has a layered structure like brucite (Mg(OH)₂), but some of the divalent cations (such as Mg²⁺) are replaced by trivalent cations (such as Al³⁺). HT as a heterogeneous catalyst is particularly attractive because it is easy to separate and resistant to high temperatures. HT as a catalyst can be used in hydrocracking reaction to produce biofuel. Metal impregnation on HT is very promising to enhance catalytic activity especially with the bifunctional mechanism of catalyst. Ni-V metal impregnation has been successfully carried out on HTc using wet impregnation method which is indicated by the results of X-Ray Diffraction (XRD) which shows the emergence of typical peaks of both metals and HTc in 2θ = 35‒70⁰ for HTc, 2θ = 37.22⁰ (NiO) and 37.35⁰ (V2O5) regions, 2θ = 43.58⁰ for NiO, 2θ = 61.26⁰ (V) and 63.07⁰ (Ini). Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX) show a shape that is consistent with the characteristics of HT, namely the shape of the particles layered overlapping each other. In addition, the particle size of HTc is quite small with a scale of 1 μm indicating a particle size of hundreds of nanometers. EDX mapping shows that Ni and V have been dispersed evenly on the HTc surface. Based on the results of N2 adsorption-desorption isotherms, it shows that mesopores are formed which are characterized by hysteresis loops. Ni-V metal impregnation increases the surface area up to 19.915 m2/g and the pore diameter up to 37,642 nm. The results of the Waste Cooking Oil (WCO) hydrocraking reaction show that Ni-V metal impregnation can reduce the carboxylic acid composition up to 67.81% and increase hydrocarbons up to 15% at 10% Ni-V/HTc 1:2.
