Abstract

The variety and production continue of plastic has increased and it has brought difficulties in dealing with plastic waste disposed to nature and cannot be decomposed in a long time. Modified thermoplastic starch derived from sago palm crosslinked with polyurethane prepolymer obtained from diphenyl methane diisocyanate and castor oil polyol had better mechanical, thermal and chemical characteristics than bioplastics. In this study, eco-friendly plastics from sago starch modified with prepolymer polyurethane with the addition of chitosan as additive and polypropylene or polyethylene as matrix was produced. The research method conducted were consisting of several stages, preparation of thermoplastic starch, blending thermoplastic starch with polypropylene or polyethylene and plastic irradiation technology using gamma rays with dosage of 5, 10 and 20 kilogray (kGy). The effect of radiation technology on surface morphology of sago based eco-friendly plastic was analysed through Scanning Electron Microscopy (SEM) analysis to observe the effect of gamma rays exposure to the plastic surface. The result showed that the dots appearance on the surface and possibly shown non-uniformity of plastic surface due to less homogeneity of mixture when stirred. Thermoplastic starch was not blended perfectly into PP and this could be due to high temperature different required to melt PP while thermoplastic starch as an organic material cannot stand high temperature and become scorched at high temperature. To overcome this problem, mixing time should be increased to ensure high homogeneity. Overall, SEM analysis showed radiation does not provide effect to plastic surface morphology, which means it did not ruin the polymer structure as well as its binding. Similar appearance observed on the plastic surface morphology before and after radiation, even with highest radiation dose. From the analysis, it can be stated that radiation technology does not influence plastic surface structure, hence plastic binding was remain the same

Abstract

Background and Aim: Blang Asan Village has economic potential in the brick production sector; however, production activities are still conventional and have not integrated innovations in construction material technology. In addition, unmanaged Low-Density Polyethylene (LDPE) plastic waste contributes to environmental problems. This community service activity aimed to implement a circular economy concept by transforming LDPE plastic waste into environmentally friendly construction materials in the form of eco-paving blocks. Methods: The program was implemented using an experimental and participatory approach involving local partners through socialization, technical training, and construction implementation assistance. Laboratory testing was conducted on six specimen variations molded using 3 kg hexagonal molds. The mixtures consisted of LDPE plastic waste, fine aggregate, coarse aggregate, cement, and varying amounts of used oil. Compressive strength tests were performed to determine the optimal composition. Results: The compressive strength test showed that the best composition was obtained with 15% LDPE without an oil mixture, producing a compressive strength value of 24.2 MPa. Based on SNI 03-0691-1996 standards, the product met the B Quality criteria, making it suitable for parking area applications. The program successfully transferred technology to local brick craftsmen, enabling them to independently produce eco-friendly construction materials. Conclusion: The application of LDPE-based eco-paving blocks effectively reduced plastic waste while creating value-added construction products with economic potential. This program also supported the development of sustainable green economy practices in Blang Asan Village.

Abstract

Korosi merupakan proses kerusakan logam akibat interaksi dengan lingkungan korosif yang dapat menyebabkan penurunan nilai mutu dan fungsi material. Analisa ini bertujuan untuk mengevaluasi efektivitas ekstrak daun kelor (Moringa oleifera) sebagai inhibitor korosi alami pada baja karbon rendah tipe ST 41. Uji dilakukan menggunakan metode perendaman dalam larutan NaCl 3,5% yang ditambahkan inhibitor dengan variasi konsentrasi 0,12; 0,14; 0,16; dan 0,18 g/ml, serta waktu perendaman selama 8, 12, 16, dan 20 hari. Laju korosi diukur menggunakan metode kehilangan berat (weight loss). Hasil analisa menunjukkan bahwa peningkatan konsentrasi inhibitor dan lamanya waktu perendaman secara signifikan menurunkan laju korosi. Penurunan ini disebabkan oleh terbentuknya lapisan pasif protektif di permukaan baja. Efisiensi tertinggi tercapai pada konsentrasi 0,18 g/ml selama 20 hari, dengan laju korosi sebesar 64,63 mpy dan efisiensi inhibisi 57,74%. Temuan ini menunjukkan bahwa ekstrak daun kelor berpotensi sebagai bahan ramah lingkungan untuk menghambat korosi logam.

Abstract

Based on data from the Central Statistics Agency, most land in Indonesia has experienced degradation. Total area of critical land in Indonesia reaches 9,681,356 hectares, much of which is utilized for plantation activities. One of the regions significantly affected by this condition is Aceh Province, where extensive plantation areas are dominated by ultisol soils. The soil in this area is characterized by acidic conditions, low organic carbon content (approximately 0.5–2%), and moderate to very low total nitrogen levels (<0.50%), indicating inherently low soil fertility. These conditions ultimately result in reduced crop productivity, highlighting the urgent need for sustainable soil amendment strategies that can simultaneously improve soil chemical properties, enhance soil structure, and restore long-term soil fertility.  To address this issue, the utilization of biochar derived from biomass waste, such as coconut shells, is considered a promising solution. Biochar has been widely reported as an effective soil amendment capable of mitigating soil degradation, improving soil fertility, and supporting sustainable agricultural systems. However, the effectiveness of biochar is strongly influenced by its physicochemical properties, which are determined by both carbonization conditions and activation methods. In this study, the use of NaOH as an alkaline activator is expected to not only increase biochar surface area and reactive sites but also contribute to soil pH adjustment, which is particularly beneficial for acidic ultisol soils. This study aims to directly evaluate the effect of NaOH-activated biochar on plant growth and analyze the characteristics of the resulting biochar based on SNI 7763:2024. The biochar was produced through a carbonization process with varying residence times of 30, 45, 60, and 75 minutes at a temperature of 300 °C, followed by chemical activation using NaOH solutions with concentrations of 1, 1.5, 2, and 2.5 N for 3 hours to obtain optimal biochar characteristics. The results demonstrated that NaOH-activated biochar had a highly significant effect on plant height. The application of activated biochar improved soil structure by enhancing texture and porosity, reduced soil acidity, and promoted root development, which collectively increased nutrient availability and uptake by plants. The best moisture content and pH were achieved at 75 minutes of carbonization with 2.5 N NaOH, reaching 8.88% and 9.5, respectively. The highest C-Organic content was obtained at 30 minutes of carbonization and 2.5 N NaOH concentration, which was 55.80%. The relatively high C/N ratio indicates that the biochar is highly potential as a soil amendment to enhance soil fertility and crop productivity. Overall, NaOH-activated biochar had a highly significant effect on plant height by improving soil structure and creating more favorable conditions for plant growth.
