Abstract

Maggot is known to have a high content of protein and crude fat, which is 45-50% and 24-30%, respectively. This study aimed to determine the effect of maggot (Hermetia illucens) flour feed on the growth and survival of tilapia (Oreochromis niloticus) fish and to determine the best concentration of maggot (Hermetia illucens) flour feed on the growth and survival of tilapia (Oreochromis niloticus) fish. This research was conducted at the Fish Breeding Center of Gorontalo City from May to June 2024. This Study used an experimental method, consisting of 4 treatments and 3 repetitions. The treatment groups were P0 (0% maggot flour), P1 (25% maggot flour), P2 (50% maggot flour), and P3 (75% maggot flour). The data collection technique was obtained in 3 ways: calculation of absolute weight growth, absolute length escalation, and survival rate. The absolute increase in length and weight was analyzed by Analysis of Variance One Way using the F-test. Meanwhile, the survival of tilapia used a non-parametric test (Kruskall-Wallis test). Based on the analysis, it obtained that the average absolute length P3= 1.92 cm, P2= 1.51 cm, P1= 1.49 cm, and P0= 1.62 cm; average absolute weight P3= 1.43 gr, P2= 1.18 gr, P1= 1.14 gr, and P0= 1.25 gr; average of survival rate P3= 86.67%, P2= 80%, P1= 76.67%, and P0= 1.25%. In conclusion, the combination treatment of commercial feed and maggot (Hermetia illucens) flour did not have a significant effect on the length, weight, and survival rate of tilapia (Oreochromis niloticus) fish, with P>0.05.

Abstract

The construction of the Gorontalo State Administrative Court Office Building, initiated in August 2023 and scheduled for completion in June 2024, presents significant risks due to its fluctuating nature, extensive workload, and constrained time and budget. These factors critically affect productivity, quality, and costs. This study aims to evaluate project risks and identify dominant risks using the Probability Impact Matrix (PIM) method. Data were collected through questionnaires distributed to 30 respondents and analyzed using SPSS software to ensure validity and reliability. The analysis identified 26 valid risks, with three dominant risks emerging as high-priority concerns: material price increases (risk score of 20), material availability issues (risk score of 16), and delays in material procurement (risk score of 16). These risks fall within the high-level category and require immediate mitigation to minimize their adverse impact on project timelines and financial stability. Effective risk management strategies, including supplier diversification, long-term procurement agreements, and inventory control, are essential to mitigating these risks. Additionally, proactive planning and continuous monitoring are necessary to ensure project completion within the allocated time and budget. The findings of this study provide valuable insights for project managers and stakeholders in addressing critical risk factors in high-risk construction projects. Future research should explore advanced risk assessment models and mitigation techniques to enhance construction project resilience.

Abstract

Efficient scheduling methods are crucial in housing construction projects to minimize delays and optimize time management. This study investigates the impact of scheduling methods on project duration, highlighting the inefficiencies caused by mismatches between scheduling techniques and project characteristics. The research focuses on implementing the Linear Scheduling Method (LSM) for housing project scheduling and comparing it with conventional scheduling methods. LSM is particularly effective for repetitive construction projects, as it enables continuous work progression and minimizes task interference. By systematically organizing workgroups and sequencing activities, LSM ensures smoother workflow transitions and reduces idle time. A case study on the Citra Agrindo III Housing Project reveals that using LSM significantly improves time efficiency. The completion time is reduced from 384 days to 207 days, demonstrating a remarkable 177-day reduction compared to the existing scheduling approach. The findings highlight LSM's advantages in managing project timelines more effectively by streamlining workflow, preventing overlapping activities, and optimizing resource allocation. This research underscores the importance of selecting appropriate scheduling methods based on project characteristics to achieve better efficiency. The application of LSM in housing project scheduling proves to be a more effective approach, offering substantial time savings and improved project execution. Future research can further explore LSM’s adaptability across different construction project scales and complexities to enhance its implementation in the industry.

Abstract

This study aims to determine the influence of refugia plants on the population, abundance, and biodiversity of natural enemies. The research was conducted from February to June 2024 in North Toto Village, Tilongkabila District, Bone Bolango Regency, Gorontalo Province. A randomized block design (RAK) was used with three treatments: control (P0), refugia (P1), and chemical insecticide (P2), each repeated four times. Data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan's Multiple Range Test at a 0.05 significance level. Results showed that predator natural enemies consisted of 7 families in the control (P0), 9 families in the refugia treatment (P1), and 5 families in the insecticide treatment (P2). The dominant families were Coccinellidae (48.65%) in P0, Libellulidae (28.57%) in P1, and Sphecidae (44.44%) in P2. The population of natural enemies in refugia was higher at 21 and 35 HST. The diversity index in all treatments was categorized as moderate. For pollinators, P0 had 3 families, P1 had 7, and P2 had only 3, with Apidae dominating all treatments, particularly in P1 (27 individuals). The population of pollinators in refugia reached 3.50 individuals at 63 HST, higher than in other treatments. Refugia treatment was dominated by Apidae (35.06%), Nymphalidae (18.18%), and Andrenidae (15.58%). The findings highlight the positive role of refugia in supporting natural enemy populations and the negative impact of insecticides on biodiversity.

Abstract

Bricks are artificial stones made from clay, with or without additional materials, dried and fired at high temperatures to achieve durability. This study aims to analyze the characteristics of sediment from the dredging of Lake Limboto, determine the optimal mixture composition of sediment and clay for brick production, assess the compressive strength of bricks using this mixture, and outline the brick-making process. The research utilizes primary data collected through field surveys, interviews, and observations in Ilohungayo Village, Batudaa District, Gorontalo Regency. After molding and drying, compressive strength tests were conducted on different sample compositions. The results indicate that sediment-based bricks have lower water content than clay-based ones. In Sample I, the highest water content (77.9%) was observed in a 50% sediment and 50% clay mixture, while the lowest (35.9%) was in 100% clay. In Sample II, the highest water content (79.1%) was in 100% clay, while the lowest (34.1%) was in a 70% sediment and 30% clay mixture. Compressive strength tests revealed that all samples fell below the SNI 15-2094-2000 standard for red bricks but met the SNI 03-0349-1989 standard for concrete bricks, classified as class III and IV solid bricks. The study concludes that incorporating Limboto Lake sediment into brick production enhances cost-effectiveness and sustainability by reducing sediment accumulation in the lake while producing stable and economical bricks.

Abstract

Occupational Health and Safety (OHS) is a crucial aspect of construction project management to minimize the risk of work-related accidents that may hinder project completion. This study aims to analyze, evaluate, and design a risk management model using the Hazard Analysis Method. The research was conducted through literature studies and direct observations to identify existing risk variables. Data testing employed validity and reliability tests to ensure response consistency, where an R calculated value of ≥ 0.6 indicated high reliability. Once valid and consistent data were obtained, the analysis was carried out using a risk matrix to determine the probability and impact levels of risks. The findings indicate that workplace accidents in construction projects can be classified based on resource categories with varying risk levels. The implementation of OHS policies, regular training, and scheduled supervision has proven effective in reducing the risk of work-related accidents. Therefore, proper OHS risk management can enhance workplace safety and improve the efficiency of construction projects.

Abstract

The increasing demand for electricity, environmental pollution, and global warming are major challenges today. One potential solution is the utilization of biomass as an alternative energy source. This study explores the conversion of agricultural waste, specifically corn stalks, into electrical energy using a Thermoelectric Generator (TEG) on a small scale. An experimental method was employed with series and Paralel configurations to analyze system efficiency. The results indicate that after 90 minutes, the maximum power output during supercapacitor charging was 0.684 W for the series configuration and 0.301 W for the Paralel configuration. Without supercapacitor charging, the power output was 0.4118 W for the series and 0.175 W for the Paralel configuration. In terms of converted energy, the series configuration produced 33.7 Wh, while the Paralel configuration generated 35.75 Wh. These findings suggest that although the series configuration is more efficient in generating peak power, the Paralel configuration yields a higher total energy conversion. This study provides insights into biomass utilization as a sustainable energy source in Gorontalo.

Abstract

On-street parking often occurs due to limited parking spaces, especially in high-activity areas. Nani Wartabone 1 Street (formerly Pandjaitan Street) experiences significant side friction, particularly from parking activities, impacting road performance. This study evaluates the street’s performance under these conditions using field data collection and analysis based on the MKJI 1997 guidelines. Data were collected on Monday, Wednesday, and Saturday. Traffic flow recorded was 1,124 vehicles per hour on Monday, 1,146 vehicles per hour on Wednesday, and 1,341 vehicles per hour on Saturday. The degree of saturation (DS) due to on-street parking was 0.59, 0.56, and 0.52, respectively, placing the road service level in category C. Without on-street parking, the service level improved to category B, with DS values of 0.44, 0.41, and 0.39, respectively. These results indicate that on-street parking negatively affects road performance. The highest parking accumulation occurred between 8:00–9:00 PM on Saturday, June 15, 2024, reaching 130 vehicles per hour. The parking index exceeded 100% for cars, indicating insufficient parking space, while motorcycle parking remained fully occupied. These findings highlight the need for better parking management to improve traffic conditions on Nani Wartabone 1 Street.
