Abstract

The development of bioethanol based on local biomass is an important strategy to support national energy diversification. Still, the potential of Bengkulu biomass and its technical feasibility have not been systematically studied. This study aims to analyze the potential of cassava waste, coconut coir, oil palm empty fruit bunches (OPEFB), and water hyacinth as raw materials for second-generation bioethanol production, and to identify the multidimensional challenges associated with their conversion processes. The method employed is a Systematic Literature Review (SLR) with a qualitative thematic synthesis, based on the PRISMA 2020 guidelines. The search was conducted across five major databases (Scopus, Web of Science, ERIC, IEEE Xplore, and ScienceDirect) with a publication range of 2018-2025, resulting in 414 articles. Twelve articles met the criteria after a quality assessment using MMAT. The results indicate that the utilization of local biomass in Bengkulu remains fragmented. However, there is significant technical potential, including an ethanol yield of 75-180 L/ton of cassava waste, coconut coir through pretreatment with DES/NADES, OPEFB ±10% (v/v) with adaptive yeast, and water hyacinth at 7-8 g/L through SSF. The study offers a multi-feedstock conceptual framework and recommends pilot plants, LCA analyses, and economic studies to support sustainable regional implementation.

Abstract

This study aimed to determine the effect of administering chitosan nanoparticles loaded with Jatropha multifida L. stem extract on the erythrocyte count of Mus musculus infected with Plasmodium berghei as well as their characterization results. The method used was the preparation of chitosan nanoparticles loaded with J. multifida L. stem extract using the ionic gelation method. Characterization results using Particle Size Analysis (PSA) showed that the chitosan nanoparticles loaded with J. multifida L. stem extract had an average particle size of 567.12 nm with a polydispersity index (PDI) value of 0.11, while characterization using X-ray diffraction (XRD) showed the highest peak at a 2θ angle of 28.68°. The results indicated differences in the effects of varying concentrations of chitosan nanoparticles loaded with J. multifida L. stem extract on erythrocyte counts. The conclusion of this study is that the most effective dose of chitosan nanoparticles loaded with J. multifida L. stem extract was 0.028 g/kg body weight, followed by the administration of crude J. multifida L. stem extract at the same dose.   Keywords: Erythrocytes, Jatropha multifida L., Chitosan, Nanoparticles, Particle Size Analysis, Plasmodium berghei, X-ray Diffraction

Abstract

The utilization of aquaculture, especially in freshwater fish farming potential, is still not optimal. In general, fish feeding is still done manually and depends on human resources which is done simply. So an automatic fish feed thrower based on solar cells was designed to minimize the risk of delays in feeding fish. This innovation can be integrated in learning where it is adapted to physics content. This research uses a mix of methods with data collection techniques in the form of observations related to the surrounding environment and the learning process, documentation in the form of learning tools such as syllabus, lesson plans, curriculum, documentation, questionnaires, testing feed machine tools and literature studies. This research instrument is in the form of descriptive observation sheets, observation analysis sheets testing feed machine tools. Analytical techniques in this study use descriptive, qualitative and quantitative analysis techniques. The results of this research are in the form of content integration in physics learning in the context of designing a solar cell-based automatic fish feed throwing machine consisting of 6 physics contents that are adapted to the context of solar cell-based automatic fish feed throwing machines. The results of this study show that the application of the use of an automatic machine for throwing fish feed based on solar cells can be used as a source of learning, especially in physics subjects.

Abstract

This research aims to analyze the needs and specifications of the Renewable Energy Literacy through the Exploration of Various Natural Materials (RELIEVE) e-module, which is integrated with STEM-PjBL to support applied science learning in universities. This qualitative research involved five lecturers who were selected purposively, with data collected through semi-structured interviews, then transcribed, verified, and analyzed using a thematic approach. The results of the study show three main findings. First, students need learning that is applicable, contextual, interactive, and problem-solving based to develop critical and creative thinking skills. Second, the STEM-PjBL approach is considered appropriate because it is able to integrate science, technology, engineering, and mathematics concepts through contextual projects that increase student learning engagement. Third, the required e-modules must be digital, easily accessible through devices, structured, project-based, and provide authentic assessments to measure high-level thinking skills (HOTS), especially critical and creative thinking skills. These findings confirm that the development of the RELIEVE e-module has the potential to be a strategic pedagogical innovation to strengthen renewable energy literacy and support the sustainable energy transition while contributing to curriculum development and further research on the effectiveness of STEM-PjBL-based learning in higher education.

Abstract

The presence of ammonia in waters needs to be monitored because of its toxic nature, especially in the form of free ammonia (NH₃). High concentrations of free ammonia can disrupt the balance of aquatic ecosystems, reduce dissolved oxygen levels, inhibit the growth of aquatic organisms, and even cause mass mortality in fish and other biota. The purpose of this study is to build the Digital Image Colorimetry system for detecting ammonia and assess the accuracy of the DIC method compared to the well-known established spectrophotometric method. Analysis from 5 locations of saline water, salinity and pH levels were still within normal limits, ranging from 33-34 ppt for salinity, while pH is 7.5-7.9. The ammonia content at the sampling point was still considered safe, in accordance with the quality standard (0.3 ppm). The results of ammonia concentration measurements using the DIC method and the spectrophotometric method show a neglegible level of difference and have an accuracy value above 90%. These findings indicate that DIC can be used as an alternative method for measuring ammonia, especially for rapid analysis in the field.

Abstract

High fermentation temperatures will remain a major limitation to competitive bioethanol production in tropical countries and regions. The objective of the present study was to enrich indigenous microbial strains, improve their performance through Adaptive Laboratory Evolution (ALE), and identify a promising candidate for sustainable bioethanol production. A design an exploratory-comparative laboratory study design was used. Four isolates, Candida tropicalis (CT-BKL01), Kluyveromyces marxianus (KM-BKL02), Bacillus coagulans (BC-BKL03), and Zymobacter palmae (ZP-BKL04), were isolated, characterised, and evolved at elevated temperatures (up to 60 generations). Statistical methods included t-tests (paired and unpaired), fold-change values from proteomics, and nonlinear regression using the Monod-Haldane model. ALE results showed ALE significantly increased the specific growth rate, the activity of the enzyme (p < 0.05), and promoted overexpression of HSP70, GroEL, and ADH-II, whereas its improvement in ethanol titer was observed at 45 °C, with BC-BKL03 as the best strain exhibiting μmax of 0.63 h-¹ that had strong model-appropriate fits (R² ≥ 0.98). From a scientific point of view, this study offers an excellent non-recombinant approach for strain improvement without genetic modification. Operationally, this work contributes to SDGs 7 (Affordable and Clean Energy) and SDGs 13 (Climate Action) by enabling efficient production without active cooling. It enables regional energy sovereignty and reduces carbon emissions, offering a scalable solution for the renewable energy industry in tropical countries.
