Abstract

Unsignalized intersections often become critical points of traffic problems due to increasing traffic volume that is not balanced with intersection capacity, resulting in delays, queues, and potential conflicts, especially during peak hours. This condition also occurs at the Unida Intersection (Universitas Iskandarmuda) in Banda Aceh, which serves traffic movements from campus areas, residential zones, and surrounding commercial activities. This study aims to analyze traffic flow characteristics and intersection performance using the Indonesian Highway Capacity Guidelines (PKJI 2023). The data used include traffic volume and geometric conditions of the intersection, which are then analyzed based on parameters such as capacity, degree of saturation, delay, queue probability, and level of service. The results show that the highest traffic volume occurs during the afternoon peak hour, reaching 1,089 pcu/hour, with a degree of saturation of 0.65. The average intersection delay is 12.989 seconds per vehicle, with a queue probability ranging from 17.47% to 36.09%. The level of service is classified as C, indicating that traffic flow remains stable but begins to be affected by congestion. Overall, the intersection still operates adequately however, further evaluation is needed to anticipate future increases in traffic volume.

Abstract

Failure of slip yoke components in palm oil transport vehicle transmission systems is generally caused by complex and cyclic dynamic loading. This study aims to analyze stress distribution and predict failure locations using a Metode Elemen Hingga (FEM)-based approach. A three-dimensional model was developed from actual geometry with controlled simplification using AISI 4140 material. Mesh convergence and quality evaluation were conducted to ensure numerical reliability. The results show that maximum stress increases with load, reaching 196.14 MPa, 294.38 MPa, 392,40 MPa, and 490.52 MPa for loads of 4, 6, 8, and 10 tons, respectively. At 10 tons, the stress exceeds the material yield strength (415 MPa), indicating plastic deformation. Stress concentration occurs at the critical section (C–C) due to geometric discontinuities and combined loading, consistent with observed failure locations. Comparison with analytical results shows less than 1% deviation, confirming model accuracy. This study demonstrates that FEM effectively predicts stress distribution and failure mechanisms, providing a basis for design optimization and maintenance strategies.

Abstract

Household food security is an important factor influencing nutrient intake, including carbohydrate intake as the main source of energy. This study aimed to determine the relationship between household food security and carbohydrate intake among women of reproductive age in Selo District, Boyolali. This research used an analytic observational design with a cross-sectional approach involving 108 respondents selected using simple random sampling. Household food security was measured using the Household Food Insecurity Access Scale (HFIAS), while carbohydrate intake was assessed using a Semi Quantitative Food Frequency Questionnaire (SQ-FFQ). Data were analyzed using the Spearman Rank test. The results showed that the majority of respondents were classified as food insecure (59.3%), with carbohydrate intake predominantly in the excessive (46.3%) and normal (38.9%) categories. Statistical analysis revealed a significant relationship between household food security and carbohydrate intake (p = 0.030) with a weak negative correlation (r = -0.209). It can be concluded that higher levels of food insecurity are associated with lower carbohydrate intake.

Abstract

The peel and seeds of tamarillo (Solanum betaceum Cav.) are sources of anthocyanin pigments with potential application as natural dyes for a more environmentally friendly textile industry. The widespread use of synthetic dyes, which still dominates today, poses negative impacts on both the environment and human health. Therefore, this study was conducted to evaluate the quality of the resulting extracts. The parameters assessed included acidity level (pH), anthocyanin content based on UV-VIS absorbance values, color characteristics, and color fastness in accordance with the SNI ISO 105-A03:2010 standard. The results showed that the duration of maceration had a significant effect on the quality of the extracts. For the peel extract, the optimal condition was obtained at pH 3, with an anthocyanin content of 65.12 mg/L, an absorbance value of 0.391, and color fastness at a scale of 4–5, which is categorized as very good. Meanwhile, the seed extract exhibited optimal results at pH 3, with an anthocyanin content of 127.07 mg/L, an absorbance value of 0.761, and color fastness at a scale of 4, which falls under the good category. Overall, these findings indicate that tamarillo peel and seeds have significant potential as a sustainable source of natural textile dyes and can serve as a safer alternative to synthetic dyes.

Abstract

Manual production of coconut shell briquettes in small and medium-scale industries often faces limitations in productivity, product uniformity, and dependence on human labor. This study aimed to evaluate the efficiency improvement of coconut shell briquette production through the use of a 10 kg-capacity briquetting machine. An experimental method was applied by comparing mechanical briquetting and manual hand-pressing using the same raw material composition, namely 7 kg of coconut shell charcoal powder, 3 kg of tapioca starch adhesive, and 1 liter of water as a mixing aid. The observed parameters included production capacity, production time, physical quality score, quality consistency, and electrical energy consumption. The results showed that the machine produced 10 kg of briquettes in 1 hour, whereas the manual method produced approximately 3.3 kg per hour and required about 3 hours to reach the same production quantity. The machine increased production capacity by approximately 200% and reduced production time by approximately 67%. The physical quality score increased from 70% to 85%, while quality consistency increased from 80% to 95%. Although the machine consumed 0.5 kWh per process, the energy requirement was relatively low, equivalent to 0.05 kWh/kg of briquettes. These findings indicate that the 10 kg-capacity briquetting machine is feasible as an appropriate technology to improve productivity and product uniformity for small and medium-scale coconut shell briquette producers.

Abstract

The increasing demand for electricity continuously emphasizes the importance of developing renewable energy sources. Indonesia, as a country consisting of many islands, has significant potential to utilize energy from ocean waves, one of which is by using Oscillating Water Column (OWC) technology that can convert wave energy into electrical energy. The purpose of this study is to estimate the electrical energy generated by the OWC type Ocean Wave Power Plant (PLTGL) in the Makassar Strait using the Gradient Boosted Tree Regression (GBT) method. Two approach schemes are used in this study, but the focus of the discussion is on the first scheme, namely the indirect approach. In this approach, predictions are first made on four main variables, namely significant wave variables (Hsig), maximum wave height (Hmax), wave period (wave period), and wind speed (wind speed). The results of the main variable predictions are then used to calculate the electrical power generated by the PLTGL-OWC. The maximum power is estimated to be 23,926 Watts on January 3, 2025 at 12:00, and the minimum power is 3,256 Watts on January 7, 2025 at 19:00. This approach is effective for predicting the power output of ocean wave generators in the Makassar Strait.

Abstract

Breakfast plays an important role in supporting students’ daily activities as it serves as the primary source of energy for both the body and brain. A carbohydrate-rich breakfast can help maintain blood glucose levels, improve concentration, and enhance focus and productivity during learning activities. In contrast, skipping breakfast may lead to decreased energy, impaired concentration, and fatigue, which can negatively affect academic performance. This study aimed to analyze differences in total breakfast macronutrient and micronutrient intake and their effects on lunch consumption among students at Aceh Health Polytechnic. A true experimental approach with a Cluster Randomized Controlled Trial (CRCT) design was employed involving 32 students selected through universal sampling. Data were collected using questionnaires from August 30 to September 12, 2024, and analyzed using paired t-test, One-Way ANOVA, and non-parametric alternatives when assumptions were not met, using STATA software. The results showed no significant differences in any of the variables examined among the 6373 group, the 7383 group, and the control group (p > 0.05). Although differences in mean nutrient intake were observed, these differences were not statistically significant, while fat intake showed a tendency toward significance (p = 0.098). The intervention did not significantly affect either macronutrient or micronutrient intake. Future studies are recommended to involve larger sample sizes, longer intervention periods, and improved dietary intake monitoring to obtain more accurate results.

Abstract

Soil compaction is crucial in civil engineering as it affects soil shear strength, compressibility, and permeability, which determine infrastructure stability. Natural soils often have low bearing capacity, especially in clay layers, requiring thorough laboratory testing to identify appropriate compaction methods. This study compares the effectiveness of Modified Proctor tests using two procedures: Method A (No. 4 sieve) and Method C (3/4-inch sieve), applied to clay soil from Blan Nisam Village, Julok Subdistrict, East Aceh. Samples were taken from 7 points at the location with the assumption that the local soil is not homogeneous and will obtain representative data variations. Tests included Atterberg Limits, specific gravity, grain size distribution, and compaction per ASTM and SNI standards. Results classify the soil as A-6 (AASHTO) and CL (low to medium plasticity cay, USCS). Method C produced higher maximum dry unit weights which resulting a higher compaction value than Methode A. Meanwhile, Method A showed higher optimum moisture content with lower compaction value. Method C provides more large particles thus reducing the water requirement to achieve maximum density, which is the opposite of Method A testing. These findings confirm that soil compaction is highly sensitive to gradation and plasticity, impacting strength and permeability.

Abstract

Skin infections caused by Candida albicans require safe and effective natural alternative treatments. This study aims to formulate and evaluate a topical nanogel preparation containing Zinc Oxide Nanoparticles (ZnO-NP) and aqueous extract of young areca nut (Areca catechu L.) with extract concentrations of 2%, 4%, and 6%, using Carbopol 940 as the gel base. Particle size characterization using a Particle Size Analyzer (PSA) yielded results of F0 (40±2 nm), F1 (51±3.46 nm), F2 (46.6±2.88 nm), and F3 (34.6±1.15 nm), all within the nanogel range of 20–200 nm. Antifungal activity testing against Candida albicans using the well diffusion method on PDA medium yielded inhibition zones: 6% concentration (17.22 ± 0.29 mm), 4% (13.47 ± 0.31 mm), 2% (12.58 ± 0.69 mm), positive control ketoconazole (28.62 ± 0.52 mm), and negative control (0 mm). The formulation with a 6% extract concentration (F3) yielded the smallest particle size and the largest inhibition zone, equivalent to 60.17% efficacy compared to ketoconazole. In conclusion, the ZnO-NP-synthesized young areca nut peel extract nanogel has potential as an effective topical antimicrobial formulation with dose-dependent activity.

Abstract

Deaths due to hypertension totaled 427,218, highlighting the serious impact of this disease on health. At the Bengkuring Community Health Centre, there are 1,143 elderly suffering from hypertension, making hypertension the primary cause of stroke and heart failure, particularly among elderly due to degenerative processes and a sedentary lifestyle that lacks physical activities such as exercise. The ability of the elderly to practice hypertension exercises remains very limited due to a lack of regular exercise. This situation calls for innovative and practical educational strategies, such as the use of videos, to improve hypertension exercise skills among the elderly. The purpose of this study was to analyze the effect of a hypertension exercise video on improving the skills of elderly at the Bengkuring Community Health Center using a one-group pre-test and post-test pre-experimental design. A purposive sampling technique was used to select 46 elderly. After using an observation sheet to collect skill data, the Wilcoxon test was used to analyze the statistics. With a p-value of 0.000 (p<0.05), the results of the study indicate that the skills of the elderly improved after receiving the hypertension exercise video intervention. In conclusion, education through Hypertension exercise videos is effective in improving practical exercise skills among the elderly.
