Strawberries are horticultural commodities that are highly susceptible to postharvest deterioration due to their high respiration rate, microbial activity, and oxidative degradation, resulting in a relatively short shelf life. This study aimed to evaluate the effectiveness of edible coatings in extending strawberry shelf life through a systematic literature review (SLR) approach. Literature was collected from several scientific databases using keywords related to edible coating, shelf life, and strawberry, covering publications from 2019–2026. From an initial 109 articles, a selection process based on inclusion and exclusion criteria resulted in 35 articles specifically discussing the application of edible coatings on strawberries. The synthesis results showed that all studies reported an extension of shelf life after edible coating application, although the effectiveness was influenced by the type of material, formulation, and storage conditions. Chitosan was the most widely used coating material due to its natural antimicrobial activity and excellent film-forming ability. The incorporation of bioactive compounds such as essential oils, plant extracts, and phenolic compounds was proven to enhance antifungal and antioxidant activities. In addition, nanotechnology-based systems demonstrated better preservation performance compared to conventional systems. However, methodological standardization and industrial-scale validation are still required to support commercial implementation.

Male reproductive performance serves as a foundational metric for predicting the reproductive quality traits of progeny. This study aimed to investigate the interaction between semen quality in Etawa Grade (PE) and Boer bucks and non-genetic factors, specifically age and season. The research utilised secondary data on fresh semen production collected from 2018 to 2022. Quality parameters evaluated included ejaculate volume and individual sperm motility. Data were obtained from the Central Java Artificial Insemination Center and analysed using the Statistical Analysis System On Demand for Academics to determine the interactive effects of age and season on fresh semen production. The results indicated that bucks in the younger age category tended to produce higher semen volumes compared to other age groups. In conclusion, there is a general interaction between age and season on the semen quality of PE and Boer bucks. The interaction observed in fresh semen volume and motility was significantly influenced by individual age differences and seasonal factors based on rainfall levels. Further research is warranted to investigate these interactions across additional macroscopic and microscopic parameters.

Fly ash and bottom ash (FABA) are combustion residues from coal-fired power plants. Following the issuance of Government Regulation No. 22 of 2021, FABA is no longer classified as hazardous and toxic waste (B3). However, FABA must still be managed properly due to its potential to cause pollution through leachate generated if leaks occur in the FABA disposal area. This study evaluates the lining and drainage systems in the FABA disposal area at PT. PLN Nusantara Power UP Paiton to ensure that leachate does not contaminate surrounding groundwater. The research employs descriptive qualitative and quantitative methods, collecting secondary data to assess the structure and pollution control systems in the FABA disposal area at PT. PLN Nusantara Power UP Paiton. The data includes the disposal area structure and water quality from monitoring wells. Analysis results indicate that the FABA disposal area lining system operates effectively and in compliance with regulations, successfully containing leachate movement and preventing seepage. This is supported by pH, Fe, Hg, and turbidity levels in groundwater from monitoring wells remaining within safe limits. Additionally, the presence of a runoff pond helps contain surface runoff during heavy rain, keeping overflow water under control. Overall, the disposal area structure and leachate management system at PT. PLN Nusantara Power UP Paiton function well, but routine monitoring must continue to ensure no seepage occurs, preventing leachate from contaminating the surrounding environment as an early preventive measure to maintain environmental quality and regulatory compliance.

Waste from used Polypropylene (PP) and High Impact Polystyrene (HIPS) plastic is problematic in its management. The purpose of this research is to obtain the fatigue life of a mixture of used PP and HIPS plastics in its pure plastic. The research method is through the stages of mixing pure PP and 50% volume of used PP, pure HIPS and 50% volume of used HIPS, injection molding of R.R. Moore standard fatigue test specimens for pure PP, pure HIPS, pure PP + used PP, and pure HIPS + used HIPS, checking the straightness and smoothness of the molded specimen surface, fatigue testing with increasing serial loads, analysis of the bending stress curve (S) against fatigue life (N). The results showed that mixing used PP and used HIPS in pure plastic affected the fatigue life at the test speed (n)=2100 rpm for recycled PP was 9.84% shorter than pure PP, and at n=1600 rpm for recycled PP it was 9.32% shorter than pure PP, while at n=2100 rpm for recycled HIPS it was 4.45% shorter than pure HIPS, and at n=1600 rpm for recycled HIPS is 4.77% shorter than pure HIPS, while the fatigue life of pure PP is 1627704 cycles and the fatigue life of pure HIPS is 1291636 cycles or the fatigue life of pure HIPS is 20.65% shorter than pure PP, the implication of which is that the addition of used PP and used HIPS reduces the fatigue life to 9.84% for PP and 4.45% for HIPS.

This study aims to analyze the quality of coal from the AR_10 borehole in Muara Enim Regency, South Sumatra, based on proximate analysis. The AR_10 borehole has three coal seams (A, B, and C) that were analyzed using the standard ASTM method to determine the coal quality characteristics. The parameters analyzed include total moisture (TM), volatile matter (VM), fixed carbon (FC), ash content (Ash), calorific value (CV), and total sulfur (TS) on an as-received (AR) basis. The analysis results show that seam A has the highest moisture content (19%), seam B exhibits the optimal calorific value (6045 kcal/kg), and seam C has the highest fixed carbon content (42.63%) with the highest sulfur content (0.83%). The correlation between parameters indicates that increases in moisture and ash content negatively affect the calorific value, while an increase in fixed carbon is positively correlated with the calorific value. All three seams fall into the category of low to medium rank coal (subbituminous to high volatile bituminous) with adequate quality for power generation and industrial purposes. This research provides an important contribution to the characterization of Muara Enim Formation coal in South Sumatra for the optimization of local coal resource utilization.

Profil baja IWF (Instrument Wide Flange) merupakan elemen struktur yang banyak digunakan pada bangunan industri karena kemudahan dalam pemasangan dan fleksibilitasnya. Namun, kondisi lingkungan ekstrem seperti genangan air dengan pH asam maupun basa dapat mempercepat proses demineralisasi (korosi) pada baja. Penelitian ini bertujuan untuk mengidentifikasi laju kehilangan unsur Fe dari profil baja IWF akibat perendaman dalam larutan dengan pH ekstrem, serta menyusun model matematis yang menggambarkan proses demineralisasi. Metode yang digunakan adalah uji laboratorium dengan perendaman potongan baja dalam larutan pH 4, 7, dan 10 selama 72 jam, dilanjutkan dengan uji TDS, ORP, dan morfologi. Hasil menunjukkan bahwa pada pH 4, terjadi demineralisasi Fe tertinggi sebesar 16,167 mg dengan rata-rata ORP sebesar 195,5 mV dan TDS 732,55 ppm. Berdasarkan data tersebut, dibentuk model matematis diferensial untuk memprediksi laju demineralisasi. Disarankan penggunaan pelapis (coating) yang sesuai untuk meningkatkan umur pakai struktur baja.

Many used ABS plastic wastes have problems in their management. The aim of this research is to obtain a prediction of the fatigue life of a mixture of ABS plastic and used ABS as an injection molding product. The research method is carried out through the stages of mixing used ABS with a volume of 10%, 20%, and 30% in ABS grade A and grade B; making fatigue test specimen molds according to R. R. Moore standards, injection molding of a mixture of used ABS and ABS grade A and grade B, checking the straightness and smoothness of the specimen surface, fatigue testing with increasing serial loads, analysis and making a graph of bending stress (S) against fatigue life (N) (S-N Curve). The results of the study showed that the addition of used ABS had an effect on the fatigue life of both grade A and grade B of ABS, where the fatigue life of grade A of ABS increased with the addition of the volume percentage from 0% -30% of used ABS with the highest value at the addition of 30%, namely 43698.9 cycles, while in grade B of ABS, the fatigue life decreased with the increase in volume from 0% -30% with the highest fatigue life in grade B of ABS plastic without a mixture or 0%, namely 41377.5 cycles, the implication of which is that the addition of 0% -30% of used ABS in grade A can increase the fatigue life, but grade B of ABS actually decreases its fatigue life.

Well water is still one of the main sources of daily water supply for the residents of the Candi Muaro Jambi area. The dependence on well water makes it vital for consumption, cooking, and other domestic activities. However, with the increasing human activity, the development of tourist areas, and environmental changes in the surrounding area, the quality of the well water is at risk of being affected. This study aims to evaluate the feasibility of well water from an environmental and health perspective based on physical, chemical, and biological parameters, referring to the clean water quality standards set by the Ministry of Health of the Republic of Indonesia. The research employs a descriptive quantitative method, with well water samples taken from several points around the residential areas in the Candi Muaro Jambi region. The analyzed parameters include temperature, color, odor, turbidity, pH, nitrate content, metal content (Fe and Mn), and the presence of coliform bacteria. Laboratory test results show that most of the well water samples still meet the established physical and chemical standards, but some wells were found to have coliform levels exceeding the recommended threshold. This condition indicates contamination, most likely from domestic waste, particularly from household sanitation systems that are not ideally located relative to the wells. While the well water in the study area is generally still suitable for daily use, it is recommended that the community performs simple water treatment, such as boiling or filtration, before direct consumption. These measures are crucial to reduce contamination risks and ensure the water's quality for safe consumption and health.

This study aims to determine and analyze the influence of product development, service quality, and pricing on sales volume at PT Indoqurma Sejahtera, East Jakarta. The background of this study is based on increasingly fierce business competition, especially in the trading industry, so companies need to identify factors that influence sales volume. This study uses a quantitative approach with data collection techniques through distributing questionnaires to 50 employees directly involved in marketing and sales activities, using a saturated sampling technique. The research instrument was tested for validity and reliability before use. Data analysis was carried out using multiple linear regression using SPSS software version 19, which includes the classical assumption test, t-test, F-test, and coefficient of determination. The results show that the variables of product development and service quality do not have a significant influence on sales volume. This indicates that the company's product development efforts have not been fully able to increase market appeal or have not been in accordance with consumer needs. Similarly, the implemented improvements in service quality have not had a significant impact on increasing sales volume. In contrast, pricing has been shown to have a significant influence on sales volume. These findings indicate that consumers in PT Indoqurma Sejahtera's target market are highly price-sensitive, thus a competitive pricing strategy can be a key factor in driving sales. Based on these results, managerial implications include the need to reevaluate product development strategies and improve service quality to be more relevant to consumer needs and preferences.

Sleep disturbances in infants can cause significant physiological and psychological impacts, such as decreased immune function, impaired cognitive development, and an increased risk of emotional problems (Tanty & Pramesti, 2023). Poor sleep not only inhibits physical growth but also affects infants’ mental development, including attention disorders, anxiety, and low cognitive abilities (Hendri & Sari, 2021). Therefore, it is important to provide effective interventions to improve infants’ sleep quality. This study aimed to determine the effect of baby massage on infant sleep quality at BPM Aida Nospita, Manunggal Village, Labuhan Deli Subdistrict, Deli Serdang Regency, North Sumatra Province, in 2025. This research employed a quasi-experimental method with a pretest–posttest design using an experimental group and a control group, also known as a pretest–posttest with control group design, which is a form of quasi-experimental research design. The population of this study consisted of all infants aged 3–6 months at BPM Aida Nospita, Manunggal Village, Labuhan Deli Subdistrict, Deli Serdang Regency, North Sumatra Province, totaling 32 infants, with 16 infants in the experimental group and 16 infants in the control group. The results of the statistical analysis using the Wilcoxon test showed a significant probability value of 0.001 (p < 0.05). This indicates that the null hypothesis (H₀) was rejected and the alternative hypothesis (H₁) was accepted, meaning that baby massage had a significant effect on sleep quality among infants at BPM Aida Nospita, Manunggal Village, Labuhan Deli Subdistrict, Deli Serdang Regency, North Sumatra Province, in 2025.

Dental caries is one of the most common dental health problems worldwide, caused by bacterial activity in the mouth, notably Streptococcus mutans. This bacterium plays a crucial role in tooth demineralization, ultimately leading to tooth decay. The management of dental caries is typically performed through medical procedures, such as dental fillings; however, this method does not prevent the recurrence of caries. One alternative that has gained attention is the use of herbal plants. This article explores using herbal plants as an alternative inhibitor of Streptococcus mutans bacteria in treating dental caries. The writing of this article employs a narrative analysis approach by collecting secondary data from various previous studies. The exploration results show that 33 herbal plants are used as therapies for addressing dental caries, with five plants being the most commonly used: betel leaf, Lantana camara, lime, celery, and ginger. Using herbal plants to inhibit Streptococcus mutans offers promising potential for developing more natural, safe, and affordable treatment methods.    

Accurate elevation determination is one of the crucial aspects in oil and gas exploration activities, especially in the planning and management of well areas. This study aims to identify and compare the elevation of the Digital Terrain Model (DTM) obtained from aerial photography with terrestrial measurements, and to convert Digital Surface Model (DSM) data into DTM. The urgency of this study is driven by the need for accurate, efficient, and economical mapping methods, as well as validation of the methods used in topographic mapping. Digital Terrain Model (DTM) is a virtual model that adds elements such as fault lines and observations to correct artifacts from the original data, while DSM includes the height of all objects on the ground surface. The results showed that the largest elevation value in the aerial photo DTM was 14.416 meters at point L06 and the smallest elevation value was 6.567 meters at point A46, with an average elevation of 13.716 meters. Meanwhile, the comparison results of DTM elevation of aerial photography with terrestrial measurements showed the largest difference of 5.513 meters at point A46 and the smallest difference of -2.682 meters at point L21, with an average difference of 0.072 meters. The level of vertical accuracy (Z) based on the LE90 value is 0.2076 meters, which meets the geometric accuracy standard of 1:1000 class 1 scale according to BIG Regulation Number 15 of 2014. The results of this comparison are also supported by a 3D model of DTM elevation of aerial photography. This study provides an important contribution to the validation and improvement of the efficiency of topographic mapping methods based on aerial photography, as well as providing an overview of the accuracy of the data produced.    

Hypertension or high blood pressure is defined as a continuous increase in blood pressure that exceeds normal limits (Nuraini et al., 2023). Hypertension occurs due to several factors, the first being modifiable and non-modifiable factors. Among the modifiable risk factors for hypertension are smoking and obesity. People who smoke more than one pack of cigarettes per day will be twice as vulnerable as people who do not smoke (Luh et al., 2020). The purpose of this study was to determine the correlational between smoking and BMI with the incidence of hypertension in adult men in Alassumur Lor Besuk Probolinggo. The research design used an Correlational Analytic with a cross-sectional approach. The population in this study was 35 with a total sampling technique. The research instrument used a questionnaire, then the data obtained will be tested by Spearman rank. The results of the study obtained the smoking variable ρ = 0.018, the BMI variable ρ = 0.071. This shows that there is a corelation between smoking behavior and BMI with the incidence of hypertension. Smoking behavior that is increasingly uncontrolled will cause hypertension and accumulation of fat on the walls of blood vessels can cause narrowing and hardening, increasing blood flow resistance and ultimately increasing blood pressure. It is hoped that respondents will reduce their smoking habits and start a healthy life by maintaining a diet, exercising regularly and eating nutritious foods.

Giving probiotics such as probiotic boster on feed greatly helps the growth of absolute weight in Catfish seeds because the good bacteria contained in these probiotics help facilitate catfish seeds in digesting the feed so as to increase the efficiency of the feed. This study aims to see how effective the probiotic administration is.
