Abstract

This study analyzes the implementation of the Green Mining concept by PT Semen Tonasa and its relationship with environmental sustainability, agricultural productivity, and the welfare of farmers around the mining area. The approach used is descriptive qualitative supported by simple quantitative analysis (Spearman correlation) to assess the relationship between Green Mining metrics (ISO 50001, TSR biomass, land reclamation, and CSR) and community socio-economic indicators. Data were obtained through farmer surveys, interviews with the company and local government, and a review of CSR and energy efficiency documents. The results show that land reclamation exceeded the target of 17.16 ha from 15.85 ha (91.67% success), the implementation of ISO 50001 increased energy efficiency by 18.52%, saved 1,214,159 MWh, and reduced emissions by 435,864 tons of CO₂-e. Biomass substitution increased by 1.17% to 8.13%, followed by a 22.6% increase in rice productivity and a 20% increase in farmer income (Rp 2.5–3.0 million/month). These results confirm Green Mining's significant contribution to energy and economic sustainability, but the unequal distribution of benefits requires tripartite collaboration and the application of the Just Transition principle within the Triple Bottom Line framework.

Abstract

One of the risk factors for kidney disorders is excessive pesticide exposure. Kidney dysfunction is characterized by an increase in urea and creatinine levels. Red beetroot (Beta vulgaris L) contains bioactive compounds that are considered capable of reducing the risk of kidney disorders caused by pesticide exposure. This study aimed to prove the nephroprotective effect of red beetroot (Beta vulgaris L) against kidney damage induced by mixed pesticide exposure through an experimental study on Wistar rats. This research used an experimental design with a post-test only randomized control group design. The study population consisted of male Wistar rats. A total of 36 rats were included as samples, with inclusion criteria of being healthy, aged 2–3 months, and weighing 150–200 g. Sampling was carried out randomly. The animal experiments were conducted at the Faculty of Mathematics and Natural Sciences, UNNES Semarang, while the examination of urea and creatinine levels was performed at the Laboratory of AKKES 17 August 1945 Semarang. Urea and creatinine levels were measured semi-automatically. Data were analyzed using ANOVA and Post Hoc tests. The results showed that pesticide exposure for 14 days significantly increased urea and creatinine levels (p = 0.000). Administration of red beetroot extract to rats exposed to pesticides significantly reduced urea and creatinine levels (p = 0.000), with the optimal dose being 400 mg/kg body weight. It can be concluded that red beetroot extract has a nephroprotective effect against kidney damage caused by mixed pesticide exposure.

Abstract

Ambon City, located in the Maluku Province, is experiencing rapid development. This rapid development has resulted in an increasing number of areas that should absorb water being covered by roads and buildings, leading to a decrease in water absorption into the ground and frequent flooding in several areas around the coast. This is due to the drastic increase in rainwater volume, which exceeds the capacity of drainage channels (culverts) and ultimately leads to flooding in rivers. Identifying flood-prone areas is crucial for estimating the potential impact of flooding. The results can be one of the flood mitigation efforts in the area. Geographic Information Systems (GIS) can be a solution for obtaining information on identifying and predicting flood-prone areas by creating, transforming, and analyzing field observation data into maps that show flood-prone areas. In this study, various factors and variables were collected and adjusted with specific considerations drawn from multiple references and reference materials to identify and predict flood vulnerability in the area. The analysis indicates that 5.98% of the coastal area in Teluk Ambon Baguala District has a very high vulnerability to flooding, while 58.89% of the coastal area is characterized by a high level of vulnerability to flooding.

Abstract

Forests as critical ecosystems dominated by trees, face significant threats from extensive logging for infrastructure, manufacturing, and furniture industries, leading to deforestation and associated natural disasters such as floods and landslides. To address this, innovative solutions are needed to reduce reliance on forest wood. This study introduces an eco-friendly approach by developing recycled wood from organic solid waste, aligning with Sustainable Development Goals (SDGs), particularly Goal 9 (Industry, Innovation, and Infrastructure). Using an experimental method, recycled wood was produced from materials such as eggshells, sawdust, and marble waste. The process involved cleaning, drying, and pulverizing eggshells into powder, followed by oven-drying at 110°C for 45 minutes to achieve a maximum moisture content of 4%. The powder was mixed with a 60:40 polymer matrix and waste powder, with additional fillers like wood powder and marble waste, and molded into composite materials. Mechanical tests (tensile, flexural, compressive, water absorption, and density) revealed that natural fibers, such as coconut husk, enhanced mechanical strength, though water absorption remained high. The composite’s density (0.41–0.52 g/cm³) complied with SNI 03-2102-2006 standards for particleboard. This innovation not only mitigates deforestation but also fosters sustainable industry practices and economic opportunities through accessible technology, supporting equitable and sustainable development for future generations.

Abstract

The petrochemical industry is a high-risk sector that requires comprehensive implementation of Occupational Safety and Health (OSH). PT Petro Oxo Nusantara (PT PON) is the sole producer of 2-EH (Ethyl Hexanol), NBA (Normal-Butanol), and IBA (Iso-Butanol) in Indonesia and Southeast Asia. The purpose of this study is to understand and evaluate the implementation of the Occupational Safety and Health Management System (SMK3) based on Government Regulation No. 50 of 2012. The methods used were observation, interviews, and direct participation in OSH operational activities at PT PON. The evaluation results of 166 criteria in 12 elements of SMK3 showed an achievement of 156 points (93.98%), which is classified as “Satisfactory”. PT. Petro Oxo Nusantara also has ISO 45001:2018 certification and Zero Accident awards for 2023 and 2024. The implementation of the OHSMS reflects a commitment to six integrated management systems (ISO 9001, LCO, OHSMS, ISO 14001, Halal, ISO 37001) to achieve sustainable OHS, as well as improvements in policies, training, and internal reporting. This study confirms that SMK3 at PT PON has been effectively implemented and can serve as a reference for similar industries in creating a safe, healthy, and productive work environment, with recommendations for periodic evaluation of points that have not been met and expanding training as further research.

Abstract

Hair growth disorders can be caused by many factors, one of which is oxidative stress and immunity, which can lead to baldness (alopecia). This study aims to analyze the potential of pacing leaf fractionation on rabbit hair growth. This research method is experimental in nature and conducted in a laboratory. The extraction stage uses the maceration method with 96% ethanol solvent for 3 days. The fractionation stage uses n-hexane and ethyl acetate solvents using a separating funnel. Based on the evaporation results, n-hexane fraction (FHE), ethyl acetate fraction (FEA), and ethanol fraction (FET) were obtained. Phytochemical tests for each fraction showed that FEA and FET contained flavonoids, alkaloids, tannins, saponins, and steroids/terpenoids. However, FHE only contained alkaloids and steroids. A total of 5 male rabbits were adapted and marked with 5 areas on their backs to be applied with FHE, FEA, and FET at a concentration of 50%, minoxidil 2% as K(+), and Na-CMC as K(-). Hair growth was observed for 28 days. The results showed that the activity of FET and FHE on day 28 resulted in good hair length, with an average hair growth of 2.22±0.101 mm and 2.15±0.064 mm for both fractions, and an average hair weight of 0.19±0.024 g and 0.19±0.015 g. Each fraction affected rabbit hair growth (p<0.05), The growth rate, FHE, FET, and K(+) did not differ significantly in terms of hair weight (p>0.05). However, the growth and hair weight results from minoxidil administration were still better than the overall fraction.

Abstract

Sorghum (Sorghum bicolor (L.) Moench) is a strategic cereal crop for food diversification and food security due to its nutritional advantages and high adaptability to drought. Although white sorghum varieties are ideal for human consumption, they generally have lower levels of functional compounds such as tannins compared to colored sorghum varieties. Therefore, this study aims to evaluate the response of local sorghum to raw cocopeat media stress as a biofortification method to increase tannin content (moderate target of 1–3%) and analyze seed quality as a strategic effort to improve functional food potential. This study was conducted in two stages: field testing using a Completely Randomized Design (CRD) with four levels of planting media (100% soil; soil and husk 50:50%; soil and cocopeat 50:50%; soil, husk, and cocopeat 50:25:25%) to evaluate the agronomic characteristics of local sorghum KD4 against cocopeat stress and in the laboratory for soil characterization. Soil property characterization of sorghum was performed by iodine staining (Lugol) on the pollen and endosperm of sorghum seeds, where color changes observed under a light microscope would indicate waxy, nonwaxy, or heterowaxy properties. Modification of the growing medium significantly affects the potential yield characteristics of sorghum. The cocopeat treatment (P2) has the potential to be the best growing medium composition for biofortification because it is able to maintain seed yield even when there are indications of stress, while P3 causes a drastic decrease in yield. Additionally, KD4 sorghum consistently exhibits nonwaxy texture properties, supported by genotype and phenotype testing, indicating that this variety is suitable for food processing with a soft texture.

Abstract

Exclusive breast milk is breast milk that is given to babies from birth for 6 months without adding or replacing it with other foods and drinks. Providing exclusive breastfeeding is not easy thing, many mothers complain about a lack of breast milk. Data BPS (2022) shows that exclusive breastfeeding coverage in East Java is 69.72%, while in Tuban Regency is 48.8%. from the national target of 100%. To increase breast milk production and maintain the quality of breast milk, mothers need high-protein foods or snacks, so biscuits are made to replace mung bean flour and carrot flour as an alternative snack for breastfeeding mothers. The purpose of this study is to determine the effect of mung bean flour and carrot flour substitution on protein value and organoleptic quality of biscuits. This study used True Experimental Design with (RAL), 4 levels of treatment and 6 times replication, with a ratio of wheat flour: mung bean flour: carrot flour in each treatment is P0(100:0:0), P1(70:20:10), P2(60:10:30), P3(50:30:20). The results showed that there was an effect of increasing protein levels in biscuits with the highest value of mung bean flour and carrot flour substitution in the P3 treatment. There was a significant influence on the color, taste, aroma and texture of biscuits shown by the Kruskal Wallis Test (p<0.005) and the Mann-Whitney follow-up test which showed a difference in all treatments. The conclusion of this biscuits substituted with mung bean flour and carrot flour have an effect on protein content and organoleptic quality.

Abstract

Benzoic acid is an aromatic compound (C7H6O2), was found in plant and animal tissues, and also be produced from the fermentation process of microbial metabolism. Benzoic acid and its derivatives are widely used in agriculture, health and food. Because it’s functional, the reactivity of benzoic acid and its derivatives must be understood. One of the reactivity of benzoic acid is acidity. Acidity of benzoic acid is used to predicted reaction mechanism. Focus of this research is analysis the acidity of benzoic acid and its derivatives based on resonance theory and the effect of EWG (electron withdrawing groups) and DG (donating groups) to its acidity. The data in this research is collect by literature review on November 2024. In this research, it was found that the acidity of the benzoic acid and its derivatives was influenced by the type and position of the substituent. If the substituent is EWG, the acidity is increase and when substituent is DG, the acidity is decrease. These data can be explained by resonance.
