Abstract

This study aims to determine the yield and characteristics of essential oil extracted from orange peel. Currently, citrus peel extraction is typically performed using solvents and high temperatures, which can affect oil yield and quality. In this study, a mechanical extraction method driven by hydraulic power without heating was employed, with the aim of increasing yield while optimizing the essential oil’s composition, particularly the content of bicyclic compounds and carenes compared to conventional limonene-based methods. The utilization of citrus peels, which have traditionally been treated as waste, holds significant potential for processing into value-added products, one of which is essential oil. The materials used were Sundai  peels, lemon peels, sweet orange peels, kaffir lime peels, and kasturi  peels. The results of the study indicate that sundai orange peel is more optimal compared to other varieties because it has an peel composition of 34.2125 ± 0.20%, a moisture content of 64.482 ± 0.75%, a yield of 0.779 ± 0.03%, and a density of 0.8387 ± 0.003 g/ml. Based on the chromatogram data, at least 10 major peaks with different retention times were detected, representing the components of the essential oil. The identified compounds include 3-Carene, (+)-Carene, ?-Terpinene, Octanal, bicyclic compounds (bicyclo[3.1.1]heptane and its derivatives), and Nonyl chloroformate (a minor component).

Abstract

Biomass-based power sources have been developed in response to the growing global demand for sustainable energy. With an emphasis on improving performance by adding potassium chloride (KCl), this study investigates the possibility of employing leftover pineapple and tomato peels as bio-battery electrolytes. The study used an experimental approach in which liquid extracts from fruit waste were supplemented with different KCl concentrations and fermented for 11 days. Six pineapple-based and six tomato-based cells were stacked in Parallel to get the desired operating voltage. The findings showed that with a composition of 60:10 on the fifth day of fermentation, electrochemical performance was at its best. The hybrid design exceeded the original goal of 6 V and complied with SNI IEC 60086-1:2015 regulations by successfully achieving a peak total voltage of 7.8 V. The tomato-based system achieved a higher peak efficiency of 42%, whereas pineapple-based electrolytes exhibited higher ionic conductivity. Additionally, the KCl enrichment greatly enhanced charge transfer, leading to a maximum LED illumination durability of 720 minutes (12 hours). The hybrid pineapple-tomato bio-battery with KCl addition demonstrates significant potential as a sustainable, low-cost renewable energy solution, bridging the gap between waste valorization and practical low-power electronic applications.

Abstract

In this study, we will look at the food and beverage subsector companies listed on the Indonesia Stock Exchange for the period of 2023–2024 to see how the Current Ratio (CR), Debt to Equity Ratio (DER), Total Asset Turnover (TATO), and Return on Assets (ROA) affect company value, as measured by Tobin's Q. Using secondary data culled from company financial filings, this study employs a quantitative technique. The research sample consisted of 61 firms selected through deliberate sampling. Multiple linear regression using SPSS was the analytical approach employed. It turns out that four metrics Current Ratio (CR), Debt to Equity Ratio (DER), Return on Assets (ROA), and Total Asset Turnover (TATO) have a major impact on company value simultaneously. However, the partial test results indicate that ROA is the only ratio that significantly affects company value; CR, DER, and TATO have no such effect.

Abstract

Stunting is a chronic nutritional problem in Indonesia that adversely affects children's physical growth and cognitive development. According to data from the Ministry of Health of the Republic of Indonesia (2025), the 2024 Indonesian Nutritional Status Survey (SSGI) found that the national prevalence of stunting declined from 21.5% in 2023 to 19.8% in 2024. Although this figure was 0.3 percentage points below the 2024 national target of 20.1%, it remained higher than the target set for 2025. which is 18.8%. One of the major contributing factors is inadequate protein and calcium intake among children aged 6–24 months, highlighting the need for nutritionally adequate complementary foods. Mackerel fish (Rastrelliger spp.) has considerable potential as a source of animal protein and calcium, whilst moringa leaves (Moringa oleifera) are rich in vitamins and minerals. This study aimed to develop an instant complementary feeding (MP-ASI) porridge based on smoked mackerel flour and moringa leaf flour using the foam-mat drying method with egg white as a foaming agent. The analyzed parameters included physicochemical characteristics, nutritional value, and organoleptic properties. The results demonstrated a significant interaction between ingredient proportion and foaming agent concentration on most parameters, except carbohydrate content and aroma. The optimum formulation consisted of 90% smoked mackerel flour, 10% moringa leaf flour, and 6% foaming agent. This formulation produced a high protein content and a calcium content of 1.176.45 mg/100 g; however, its protein digestibility (65%) remained lower than that of the commercial product comparator (74%).

Abstract

This study examines the kinetics of potassium sulfate (K2SO4) formation from industrial liquid waste generated by bleaching earth. The objective is to evaluate the effects of temperature and reaction time on the conversion rate of sulfuric acid, determine the reaction order, and calculate the activation energy. The process involves reacting the diluted acid-rich liquid waste with analytical-grade potassium hydroxide (KOH) under constant stirring at temperatures of 50–70°C for 20–40 minutes. The results show that conversion increases with higher temperature and longer reaction time, reaching an optimum conversion (XA) of 96.22% at 70°C for 40 minutes. Kinetic analysis indicates that the reaction follows a second order model based on the highest coefficient of determination (R2). The calculated activation energy (Ea) is 8580.048 J/mol with a frequency factor (k0) of 367.0784, expressed in the rate constant equation, adhering to the Arrhenius model (R2 = 0.844) despite slight experimental deviations. These findings highlight the potential use of bleaching earth liquid waste as a raw material for potassium sulfate production and provide insight into its reaction kinetics.

Abstract

Fecal Sludge Treatment Plants (IPLT) play an important role in treating fecal sludge before final effluent discharge or reuse. Keputih Surabaya IPLT applies an integrated treatment sequence consisting of solid-liquid separation, flow equalization, aerobic biological treatment, clarification, sludge handling, and final polishing. This study aimed to characterize Chemical Oxygen Demand (COD) and ammonia concentrations in undiluted intermediate effluent collected from the oxidation ditch outlet of Keputih Surabaya IPLT. The sample represented wastewater conditions after aerobic biological treatment, not the final effluent of the entire treatment system. COD was analyzed using the closed reflux spectrophotometric method according to SNI 6989.2:2019, while ammonia was analyzed using the phenate spectrophotometric method according to SNI 06-6989.30-2005. The results showed that COD and ammonia concentrations were 2,866.67 mg/L and 43.40 mg/L, respectively. Based on the influent flow rate of 137 m³/day, the applicable standards are 100 mg/L for COD and 10 mg/L for ammonia. Diagnostic comparison showed compliance gaps of 2,766.67 mg/L for COD and 33.40 mg/L for ammonia, with minimum removal requirements of 96.51% and 76.96%, respectively. These findings indicate that the oxidation ditch intermediate effluent still contains substantial organic and nitrogen loads. Therefore, optimization of the existing integrated treatment sequence, particularly the balancing tank, oxidation ditch, clarifier, and polishing pond, is required. Additional aerobic biofilm or moving bed biofilm reactor treatment may be considered if downstream units remain insufficient to achieve the required final effluent quality.

Abstract

Soymilk is a plant-based beverage that widely consumed due to its nutritional value. However, differences in formulation among commercial products may lead to variation in sensory quality and consumer acceptance. This study evaluated the sensory characteristic and consumer preference of five commercially available soymilk using fuzzy logic approach. Sensory assessment was conducted with 26 semi-trained panellists who evaluated six quality attributes: colour, aroma, viscosity, taste, mouthfeel, and aftertaste, using linguistic scales. The collected responses were converted into triangular fuzzy numbers for analysis. The results showed that the commercial product exhibits differences in acceptance levels, with the preference ranking S4 > S2 > S3 > S5 > S1. Taste was identified as the most influential factor in consumer acceptance with a similarity value of 0,8426, followed by mouthfeel (0,8265) that categorized as highly important. Meanwhile, color (0,9702), viscosity (0,9497), aroma (0,8318), and aftertaste (0,7954) were categorized as important. These findings indicate that fuzzy logic is a useful analytical tool for handling uncertainty in sensory evaluation and can provide practical insight for the development and optimization of commercial plant-based beverages.

Abstract

Calcium hydroxide (Ca(OH)?) waste generated from the acetylene gas industry contains a high calcium content and has potential to be utilized as an alternative raw material for calcium nitrate fertilizer production. This study presents a novel approach for the valorization of Ca(OH)? industrial waste into a value-added calcium nitrate fertilizer through a reaction and crystallization process. The effects of reaction temperature and nitric acid concentration on calcium nitrate production were investigated. The Ca(OH)? waste was initially reduced to a particle size of 100 mesh, then reacted with nitric acid at concentrations of 1, 1.25, 1.5, 1.75, and 2 N and at reaction temperatures of 50, 60, 70, 80, and 90°C for 1 hour. The obtained calcium nitrate solution was filtered, neutralized using 25% NH?OH until pH 7, and crystallized at 150°C to obtain calcium nitrate crystals. The raw material was characterized using X-ray fluorescence (XRF), while the calcium nitrate product was analyzed using inductively coupled plasma (ICP), spectrophotometry, and yield calculation. The XRF analysis showed that Ca(OH)? waste contained 98.71% calcium. At a reaction temperature of 70°C and a nitric acid concentration of 1.5 N, calcium nitrate was successfully produced with the highest calcium (Ca) and nitrogen (N) content of 21.91% and 16.74%, respectively, and produced a yield of 69.564%, which is in accordance with the Indonesian National Standard (SNI 02-2806-1992) for calcium nitrate fertilizer, which stipulates a Ca content of 19–22% and an N content of 15.5%. This study was conducted without experimental replication; therefore, statistical significance analysis was not performed. The findings demonstrate that Ca(OH)? waste from the acetylene industry can be effectively valorized into calcium nitrate fertilizer, providing an alternative strategy for industrial waste utilization and supporting circular economy principles.

Abstract

Young bamboo leaves represent a promising biomass resource for silica production owing to their high silica content. This study aims to determine the effects of different alkali solvents on the extraction and synthesis of nanosilica from young bamboo leaf ash using hydrothermal and sol-gel methods. Young bamboo leaf ash was calcined at 700°C for 4 hours, then extracted with NaOH, KOH, and Na?CO? solutions at 1–3 N at 85°C for 3 hours. The extracted filtrate was then hydrothermally processed at 120°C for 6 hours. Nanosilica synthesis was carried out using the sol-gel method by adding a 1 N HCl solution until the gel reached pH 7 to precipitate silica in gel form, then drying at 110°C to obtain nanosilica powder. The resulting product was characterized using X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), and Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX). The XRF analysis of the raw material showed a SiO? content of 68.6%, indicating that young bamboo leaf ash has potential as a source of silica. The highest yield was obtained with 1.5 N NaOH at 94.40%, followed by 1.5 N KOH at 72.59% and 2 N Na?CO? at 24.87%. XRF characterization of the product showed a SiO? content of 62.059%. The XRD results indicated that the resulting silica was dominated by an amorphous phase with a small crystalline phase, while the SEM-EDX analysis showed a dominance of Si and O elements and agglomerated particle morphology with particle sizes ranging from 206.5–563.7 nm. Based on the research results, 1.5 N NaOH is the most effective solvent for producing nanosilica from young bamboo leaf ash.
