Abstract

Farmers verify ripe coffee cherries, pick them individually, and place them in the harvest basket in the coffee harvesting process. This task typically takes 7-8 hours. During harvesting, farmers experience a physical workload that impacts their work capacity. This research aims to measure the qualitative and quantitative workload levels of the coffee harvesting process, determine the working time based on the farmers' Human Output Capacity, and calculate the total number of daily workers needed to achieve daily coffee production targets. The determination of the number of daily workers is based on the work capacity of the farmers. Farmers were categorized into two age groups: productive age (30-40 years) and non-productive age (50-60 years). Data observed included heart rate during harvest, heart rate calibration data, subjects' body characteristics, and coffee productivity. The results showed that the heaviest workload, related to verifying ripe cherries, fell into the medium category, with an energy consumption level of 3,370 Kcal per minute. The optimal working time for the coffee harvesting process is 6 hours for workers of productive age and 4 hours for workers of non-productive age. To meet production targets, 9 workers of productive age and 10 workers of non-productive age are required.

Abstract

Hypertension is a medical condition characterized by elevated blood pressure beyond normal limits. Management strategies for hypertension can be pharmacological or non-pharmacological. This study aims to evaluate the effect of administering "semundu" juice combined with yogurt on reducing blood pressure in individuals with hypertension in the Jembatan Kecil Health Center area, Bengkulu City, in 2024. A total of 28 participants with high blood pressure were randomly assigned to one of four groups: P0 (control group receiving educational leaflets), P1 (200g watermelon juice, 100g cucumber, and 20ml honey), P2 (100g Ambon banana, yogurt), and P3 (200g watermelon juice, 100g cucumber, 20ml honey, and yogurt). The Kruskal-Wallis test results indicated that the administration of "semundu" juice combined with probiotics significantly affected both systolic and diastolic blood pressure, as evidenced by a p-value of less than 0.05. All treatment groups demonstrated a reduction in blood pressure, with significant differences observed between the groups: P0 vs. P3 (p-value < 0.02), P1 vs. P3 (p-value < 0.034), and P2 vs. P3 (p-value < 0.01). These findings suggest that "semundu" juice combined with probiotics has a notable impact on lowering blood pressure in individuals with hypertension.

Abstract

The increasing volume of waste is driven by several factors, including population growth, urbanization, and changes in lifestyle. This rise in waste generation has outpaced the capacity of available landfill space, leading to the improper accumulation of unmanaged waste. This study aims to evaluate the current waste management practices, analyze the waste generation and composition, and propose an effective waste management scenario. A quantitative descriptive analysis approach was employed, utilizing waste generation and composition data measured in accordance with the Indonesian National Standard (SNI) 19-3964-1994. The proposed waste management scenario is aligned with the guidelines outlined in Sleman Regency Regulation No. 4 of 2015. The operational techniques for managing waste include stages such as storage, collection, transportation, and treatment, which are outsourced to a third party. The findings of this study indicate that the waste at eight sampling points averaged 359,250 kg/day and 4,058 m³/day. The waste composition is predominantly organic (2.48%), paper and cardboard (12.4%), and other types of waste (11.07%). The proposed processing methods focus on utilizing technologies for organic waste and residue treatment, such as Masaro technology.

Abstract

Leachate from the Final Disposal Site (TPA) in Piyungan, Yogyakarta, is a significant source of potential heavy metal contamination. This represents a serious environmental issue as it can pose a threat to human health and ecosystems. Given its significant negative impact, this study aims to evaluate the efficiency of Compost-Based Activated Carbon (CBAC) as an environmentally friendly alternative solution for reducing heavy metal concentrations in leachate. CBAC is produced through a pyrolysis and chemical activation process using 32% HCl. The study tested the ability of CBAC to adsorb Cr, Cu, and Pb from leachate samples. The results indicate that CBAC exhibits significant adsorption capacity, with the highest removal efficiency recorded for copper (Cu), reaching 52.38% in 20 minutes. The removal efficiencies for chromium (Cr) and lead (Pb) were 17.8% and 12.09%, respectively, although at different optimal times. These differences in efficiency suggest that the characteristics of each heavy metal influence its interaction with CBAC. The findings demonstrate the potential of CBAC as an effective and sustainable alternative in waste management, particularly in reducing heavy metal pollution. This study makes a significant contribution to the development of more environmentally friendly and sustainable waste management technologies, offering an innovative solution to address heavy metal contamination issues at TPA Piyungan and similar sites.

Abstract

Background: Motion capture technology is essential in sports biomechanics for analyzing human movement. Inertial Measurement Unit (IMU) sensors offer a practical alternative to camera-based systems, providing real-time motion analysis. While previous studies in badminton biomechanics have largely focused on stroke phases or lower-limb movements using optical systems, few have investigated the detailed angular behavior of upper-limb joint-particularly the wrist and forearm during specific serve types. Moreover, existing research rarely compares different serve techniques in terms of kinematics using wearable IMU-based methods.Aims: This study aims to analyze angular movement patterns of the wrist and forearm during different badminton serve techniques using IMU sensor. Understanding the wrist and forearm movements is crucial, as they directly affect shuttle control, serve conssitency, and injury risk- especiaally in high-spedd, repetitive motions like the badminton serve.Methods: Sensors were placed on the dorsum of the hand and the forearm near elbow to measure angular motion in three serves: backhand, short forehand, and long forehand.Result: Results indicate that the centroid calculation results showed that each type of serves had a different angular distribution pattern, with varying contributions from the forearm and wrist. The forearm plays a dominant role in generating power, while the wrist contributes more to directional control and stabilization. Results indicate that forearm movement is more dominant in forehand serves, while wrist movement is more pronounced in backhand serves. These findings suggest that IMU-based motion analysis can optimize badminton techniques, prevent injuries, and enhance training programs.

Abstract

Dragon fruit cultivation in Kampung Daun Baumata has faced significant challenges due to plant diseases, with farmers reporting a 15% yield reduction in 2022. This study addresses this critical agricultural problem by developing an innovative web-based expert system that utilizes Bayesian probability theory for accurate and timely disease diagnosis. The system provides farmers and agricultural stakeholders with an accessible digital tool to identify common dragon fruit diseases, including stem rot, anthracnose, and fungal infections, through symptom analysis and probability calculations. Implemented using PHP programming language and MySQL database, the expert system offers several advantages over traditional diagnostic methods. It operates independently of human experts, delivers real-time results, and provides prevention recommendations. The Bayesian approach enables the system to process uncertain information and update disease probabilities as new symptom data becomes available, significantly improving diagnostic accuracy compared to conventional methods. Field testing demonstrates the system's effectiveness in supporting farmers' decision-making processes, enabling early disease detection, and facilitating appropriate treatment measures. The implementation of this technological solution has the potential to reduce economic losses, improve crop yields, and promote sustainable farming practices in dragon fruit cultivation. By bridging the gap between farmers and agricultural expertise, this research contributes to the digital transformation of agricultural disease management in developing regions.

Abstract

Background: The dominance of domestic waste in Bantargebang Integrated Waste Management Facility (IWMF), makes the characteristics of the waste can be categorized as combustible waste, with the type of waste mostly plastic and non-plastic. Waste dumped in Bantargebang creates new problems related to environmental pollution. The Merah Putih Waste Power Plant (Pembangkit Listrik Tenaga Sampah = PLTSa) is an important thing in efforts to control air pollution and waste management, where the quantity of waste production is relatively large and needs to be handled immediately.Aims: This study aims to analyze the benefits of the Waste Power Plant in reducing air pollution at the Bantargebang IWMF.Methods: The research uses a descriptive approach to systematically describe, analyze, and explain phenomena. In addition, quantitative analysis is applied to process and interpret data in the form of numbers. Data collection methods include air pollution data analysis, where air quality monitoring data was collected between 2019 and 2024 after the PLTSa began operating.Result: Based on the data obtained, the air quality in 2019 before the PLTSa operated and after the PLTSa operated in 2024, it can be seen that the concentration of PM2.5 decreased to 33.8 µg/m³, SO2 decreased to 2.1 µg/m³, CO decreased to 1,437.0 µg/m³, NO2 decreased to 0.5 µg/m³. Furthermore, it can be seen that after the PLTSa Merah Putih Bantargebang began operating in mid-2019, it showed benefits in 2024, where most air pollutants decreased compared to 2019 (before operated), such as PM2.5, SO₂, CO, and NO₂. This decrease reflects the success of the emission control system from the waste combustion process applied to the PLTSa.

Abstract

Background: Celery (Apium graveolens) is a horticultural crop with significant economic and culinary value, particularly in Indonesia, where leaf celery is more commonly cultivated. Despite growing interest in hydroponic farming in regions such as Bangka Belitung, celery cultivation remains limited due to challenges in seed germination, especially under lowland and hot climate conditions. Celery seeds are known for slow and inconsistent germination due to hard seed coats and naturally occurring germination inhibitors like coumarin. Seed soaking in plant growth regulators (PGRs), including natural alternatives such as red onion (Allium cepa L) extract—rich in gibberellins and auxins—has been proposed to enhance germination and seedling vigor.Aims & Methods: This study aimed to investigate the effects of different soaking durations (24 and 48 hours) and concentrations (0%, 10%, 20%, and 30%) of red onion extract on the germination performance of celery seeds.Result: The results of this study indicate that a 24-hour soaking duration is the most effective in enhancing celery seed germination as under these conditions, the seeds experience only brief exposure to low oxygen levels. However, soaking seeds in red onion extract at concentrations of 10% to 30% resulted in lower germination parameters compared to the 0% because the concentration is suspected to be too high for celery seeds. Analysis of the interaction between soaking duration and extract concentration revealed that control seeds (without soaking or directly sowing) achieved germination performance comparable to the best treatment combination in terms of germination power, germination speed index, and mean germination time. At the same time, the highest vigor index and seedling length were observed in seeds treated with 10% red onion extract for 24 hours, which also showed similar performance to the control treatment.
