Abstract

Dewasa ini, nanopartikel mendapatkan perhatian istimewa di kalangan para peneliti termasuk pemerhati lingkungan karena nanopartikel memiliki luas permukaan yang sangat besar sehingga bisa dimanfaatkan lebih lanjut untuk berbagai keperluan. Penelitian ini bertujuan untuk membuat nanopartikel perak secara biosintesis menggunakan ekstrak buah anggur beserta aplikasinya sebagai pereaksi dalam mendeteksi logam berat berbahaya, khususnya merkuri (II). Buah anggur diekstraksi menggunakan air pada suhu 80°C. Setelah dicampur dengan prekursor perak nitrat, reaksi pembentukan nanopartikel perak dipercepat dengan memanfaatkan sinar matahari sebagai energi panas alami. Nanopartikel perak yang terbentuk memiliki puncak absorbansi pada panjang gelombang maksimum 420 nm, dan selektif terhadap ion merkuri (II), yang ditandai dengan berubahnya warna nanopartikel perak tersebut dari coklat kekuningan menjadi bening. Selanjutnya, kamera digital dimanfaatkan untuk menganalisis konsentrasi ion merkuri di dalam sampel. Keakuratan metode citra digital ditentukan dengan membandingkan hasil pengukurannya terhadap metode Spektrofotometri UV-Vis. Secara umum, metode citra digital dengan nanopartikel perak sebagai reagen deteksi ion merkuri dapat digunakan dengan kinerja mumpuni. Konsentrasi ion Hg (II) dari sampel lingkungan yang dianalisis menggunakan metode yang dikembangkan ini berada di bawah ambang batas yang diperbolehkan oleh Permenkes RI No. 492 tahun 2010, sehingga air lingkungan yang dianalisis masih layak dipergunakan untuk kebutuhan rumah tangga.

Abstract

This study purpose to see the levels of bioethanol produced by bagasse and corn husks with yeast, NPK and urea compositions. The method used in the study was an experiment with a predetermined ratio and fermentation time variables of 7, 14, and 21 days. Quantitative data were analyzed by calculating the average bioethanol levels and bioethanol volumes presented in table form. Meanwhile qualitative data were analyzed descriptively. The results showed that the highest bioethanol levels were in composition A (100% yeast) with a bioethanol content of 36,7% fermented for 21 days. The lowest bioethanol levels were in composition B (100% Urea) with a bioethanol content of 3,3% fermentation time of 7 days. The conclusion of this study shows that the volume of bioethanol has no effect on the levels of bioethanol produced, but this is not constant, because it can be influenced by other factors such as the duration of fermentation time, the materials used and the microbiological conditions during the fermentation process.  Keywords: Sugarcane Bagasse, Bioethanol, Corn Husk, Environmentally Friendly Technology.

Abstract

This study aims to determine the ethanol content from banana stem and corn cob residues with variations in treatment and fermentation time using a starter culture to accelerate the fermentation process. The method used was an experimental design with treatment variations and fermentation times of 9, 12, and 15 days. Quantitative data were analyzed by measuring the average ethanol content and volume produced for each treatment and fermentation time, then presented in graphical form. The results showed that the highest ethanol content was obtained in treatment A (100% yeast) with 20% ethanol after 15 days of fermentation. In conclusion, the longer the fermentation time, the higher the ethanol content; however, the effect of fermentation time was not always consistent because ethanol content is influenced by the materials used, fermentation duration, and the condition of microorganisms during the fermentation process.

Abstract

This study synthesizes recent findings on the environmental and economic sustainability of banana peel-based bioethanol production using a Life Cycle Assessment (LCA) approach. The utilization of yellow kepok banana peel waste offers significant opportunities to support clean energy transition and sustainable waste management in Indonesia. This research employs a Systematic Literature Review (SLR) method, analyzing 15 peer-reviewed articles indexed in Scopus and SINTA published between 2020 and 2025. The review follows the PRISMA 2020 framework with inclusion criteria focusing on quantitative LCA studies and economic-environmental sustainability aspects. Literature was retrieved from Scopus, ScienceDirect, MDPI, SpringerLink, and SINTA databases using the keywords “banana peel”, “bioethanol”, “LCA”, and “sustainability”. The results indicate that pretreatment and distillation stages are the main contributors to energy consumption and greenhouse gas emissions, accounting for approximately 55–65% of total Global Warming Potential (GWP). However, the implementation of coproduct systems, such as converting residues into biogas or organic fertilizer, can reduce GWP by up to 30–40%. From an economic perspective, banana peel-based bioethanol production is financially viable at a medium scale when supported by renewable energy integration and centralized waste management systems. This study highlights the critical role of LCA as an evaluation tool for waste-based energy development and underscores the need for national standards for LCA methodologies in the bioenergy sector. To the best of our knowledge, this is the first comprehensive SLR integrating LCA and economic-environmental sustainability analysis for yellow kepok banana peel bioethanol, providing relevant insights for renewable energy policy and circular waste management in Indonesia.

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.
