“…Tindakan kuratif yaitu giat melakukan pendampingan bagi masyarakat dalam mengelola sampah rumah tangga (Ismail et al, 2020;Mardhia & Wartiningsih, 2018). Tindakan preventif yang dapat dilakukan yaitu dengan mengelola sampah menjadi produk yang lebih bermanfaat (Jung et al, 2022;Kaur et al, 2021;Singh et al, 2022).…”

Pertumbuhan penduduk dan peningkatan kebutuhan konsumsi hidup masyarakat berdampak terhadap tingginya produksi sampah. Kebiasaan masyarakat yang membuang sampah sembarangan dapat berakibat buruk terhadap kesehatan dan lingkungan. Solusi yang dapat diberikan untuk dapat mengatasi masalah ini yaitu dengan memberikan tindakan kuratif dan tindakan preventif. Kotak sampah, kerap menjadi salah satu alasan untuk membuang sampah pada tempatnya. Maka dibutuhkan kotak sampah yang dapat mempermudah dalam membuang sampah. Oleh karena itu, dikembangkan kotak sampah pintar atau smart box berbasis digital dengan memanfaatkan mikrokontroler Arduino uno. Smart box dikembangkan menggunakan sensor HC-SR04. Kotak sampah didesain dengan prinsip kerja kotak sampah dapat terbuka dan menutup secara otomatis ketika seseorang membuang sampah. Selain itu, tujuan pengembangan kotak sampah ini dapat dimanfaatkan sebagai sumber belajar fisika dalam penerapan sensor ultrasonik. Penelitian ini menggunakan metode pengembangan model ADDIE. Hasil penelitian menunjukan bahwa smart box berbasis digital dinyatakan sangat layak dengan persentase kelayakan 89%. Sedangkan dari sisi hasil pemanfaatan sebagai sumber belajar fisika, respon pengguna dari guru dan siswa memiliki persentase sebesar 89% dengan kriteria sangat baik.

“…With an expanding population, a resource and energy crisis has arisen, requiring new technology to replace fossil fuels with renewable energy [1]. Greenhouse gas emissions are emitted by the utilization of fossil fuels for energy utilization in industry, in the domestic market, and in transportation, resulting in environmental pollution, global warming, and climate change [2,3] The worldwide energy demand could surge by 19% by 2040, as proposed by the International Energy Agency [3].…”

“…As discussed, biorefinery's essential aspect in the modern economy is fossil-based product replacement with renewable energy sources. These are the principal objectives of a sustainable biorefinery and bioeconomy [1]. Hence, research has focused on producing bioethanol from LCB, which is omnipresent on the earth, and can later be substituted for fossil fuel to meet this planet's energy needs [5][6][7].…”

“…It is not easy to use and valorize LCB for biofuels and other value-added products due to the rigid, recalcitrant cell walls of plants that protect them from fungi and other pathogens [3,12,13]. Therefore, pretreatment is required to reduce biomass rigidity, recalcitrance, or physicochemical resilience to increase cellulose percentage and facilitate cellulose access to enzymes [1,14]. Pretreatment is primarily concerned with transforming the molecular structure of biomass and modifying its chemical composition.…”

“…Pretreatment is primarily concerned with transforming the molecular structure of biomass and modifying its chemical composition. As part of the technical and economic aspects, pretreatments were used to enhance sugar production and reduce reaction times while reducing the need for chemicals and electricity [1,15]. Researchers have investigated how biomass can be pretreated before being hydrolyzed by studying various pretreatment methods.…”

The depletion of fossil fuels is resulting in an increased energy crisis, which is leading the paradigm shift towards alternative energy resources to overcome the issue. Lignocellulosic biomass or agricultural residue could be utilized to produce energy fuel (bioethanol) as it can resolve the issue of energy crisis and reduce environmental pollution that occurs due to waste generation from agriculture and food industries. A huge amount of sorghum distillery residue (SDR) is produced during the Kaoliang liquor production process, which may cause environmental problems. Therefore, the SDR generated can be utilized to produce bioethanol to meet current energy demands and resolve environmental problems. Using a central composite experimental design, the SDR was subjected to hydrothermal pretreatment. The conditions selected for hydrothermal pretreatment are 155 °C, 170 °C, and 185 °C for 10, 30, and 50 min, respectively. Based on the analysis, 150 °C for 30 min conditions for SDR hydrothermal pretreatment were selected as no dehydration product (Furfural and HMF) was detected in the liquid phase. Therefore, the pretreated slurry obtained using hydrothermal pretreatment at 150 °C for 30 min was subjected to enzymatic hydrolysis at 5% solid loading and 15 FPU/gds. The saccharification yield obtained at 72 h was 75.05 ± 0.5%, and 5.33 g/L glucose concentration. This non-conventional way of enzymatic hydrolysis eliminates the separation and detoxification process, favoring the concept of an economical and easy operational strategy in terms of biorefinery.
