Ade Amalia, Novi Rusnarty Usu, Farid Muhamad — Thu, 06 Feb 2025 00:00:00 +0000

This study examines fanaticism as reflected in the characters of Rainbow Rowell’s novel Fangirl, focusing on fanatical behavior and its underlying factors. Using a psychological approach to literary analysis, the study applies theories of fanaticism along with Freud’s motivation theory, to analyze the mental and emotional processes of the characters, particularly Cath Avery as a devoted fan of Simon Snow. The analysis reveals that fanaticism in the novel is characterized by obsessive attachment, emotional investment, and actions driven by an idealized perception of fictional narratives. Psychological needs such as escapism, validation, and identity formation significantly contribute to this behavior, while subconscious desires and past experiences further shape the characters’ deep devotion. These findings offer insights into the psychological foundations of fanaticism in literature, illustrating how fictional works influence individual behavior and motivation. This study enhances the understanding of the intersection between psychology and literature, emphasizing how literary characters reflect real-life psychological tendencies.

Stunting is a chronic nutritional problem affecting child growth, particularly in regions with high prevalence, such as Sulawesi Island. This study aims to compare two optimization methods, Artificial Bee Colony (ABC) and Gravitational Search Algorithm (GSA), in the Fuzzy Geographically Weighted Clustering (FGWC) analysis to group regencies and cities based on factors contributing to stunting. The data used included health and socio-economic indicators from 66 regencies/cities in Sulawesi Island. Three validity indices—Classification Entropy (CE), Separation Index (SI), and Xie and Beni’s Index (XB)—were employed to assess clustering performance. The findings indicate that the FGWC-ABC method outperformed FGWC-GSA, yielding lower CE and XB values and a higher SI value, signifying better clustering results. The FGWC-ABC method, at a fuzziness value of m = 1.5, formed two clusters: Cluster 1, comprising 49 regencies/cities with relatively lower stunting prevalence and better socio-economic conditions, and Cluster 2, consisting of 17 regencies/cities with higher stunting prevalence and poorer socio-economic conditions. This study highlights the potential of FGWC-ABC in optimizing regional classification for targeted interventions in addressing stunting. The results provide a valuable reference for policymakers in designing effective strategies to mitigate stunting issues.

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.

Lemon cichlid fish has the Latin name (Neolamprologus leleupi) is one of the ornamental fish species with a promising level of potential. The brightness of the color of lemon cichlid fish (Neolamprologus leleupi) is one of the important factors that must be considered by lemon cichlid fish farmers. This is because the brighter the color of the lemon cichlid fish, the higher the selling price, thus affecting the income of lemon cichlid fish farmers. Efforts to increase the brightness of the color of the fish can be done by adding carotenoids derived from marigold flowers (Tagetes erecta) which are mixed into the feed. The use of marigold flower flour (Tagetes erecta) in feed to improve the color of lemon cichlid fish has not been widely carried out, so this study was conducted. This study aims to determine the addition of marigold flower flour to fish feed can provide a real effect. The method used in this study is an experimental method with a completely randomized design (CRD). The main treatment carried out was the provision of marigold flower flour with different doses, namely: 1%, 2%, 3% and one control treatment (without the provision of marigold flower flour). The addition of Marigold flower flour did not give any significant effect based on the results obtained.

This study aims to evaluate the potential of Ageratum conyzoides (babadotan) extract in controlling Colletotrichum sp., the causative agent of anthracnose in eggplant (Solanum melongena L.). The experiment was conducted using a Randomized Block Design (RBD) with six treatments: negative control (F0), positive control inoculated with Colletotrichum sp. without treatment (F1), synthetic fungicide (F2), and babadotan extract at concentrations of 40% (F3), 60% (F4), and 80% (F5), with three replications each. Observed parameters included incubation period, disease incidence, and disease intensity. The results showed that treatments F4 and F5 (60% and 80% concentrations) were the most effective in suppressing the disease. These treatments extended the incubation period to 13.17 and 13.58 days, respectively. Furthermore, the lowest disease incidence was recorded in F4 (1.39% at 58 days after planting and 9.72% at 62 days) and in F5 (0% at 58 days and 2.08% at 62 days). Disease intensity also decreased with increasing extract concentration. These findings suggest that babadotan extract, particularly at 60% and 80% concentrations, has strong potential as a natural alternative to synthetic fungicides in controlling anthracnose disease caused by Colletotrichum sp. in eggplant cultivation.

In the era of globalization, product quality plays a crucial role in meeting consumer demands and maintaining a company's competitiveness. This study aims to identify the causes of product defects and provide improvement recommendations in the production process of Alfitra Bakery using the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) methodology combined with Failure Mode and Effect Analysis (FMEA). The research was conducted through field observations and interviews at Alfitra Bakery, Gorontalo, focusing on two dominant types of defects: scorched (burnt) bread and under-expanded bread. The scorched defect was found to have a Risk Priority Number (RPN) of 490, while the under-expansion defect had an RPN of 210. The main factors contributing to scorched bread include prolonged baking time, inaccurate monitoring by workers, and manual calculation of baking time. Recommended improvements involve increasing employee supervision during baking, conducting regular briefings before production, and installing automatic timers to control baking time. Meanwhile, under-expanded bread was caused by inadequate yeast in the dough, poor employee precision, excessive fermentation time, and unstable oven temperature. Recommendations for improvement include using a measuring tool for yeast dosage, improving fermentation time management, employee training, and using ovens with automated temperature control systems. These recommendations aim to reduce defect rates and improve product quality consistency. The integration of Six Sigma and FMEA proves effective in systematically identifying and resolving quality issues in the bakery industry.

The Alo Watershed (DAS Alo) is a-subwatershed of the Limboto Watershed loacted in Gorontalo Regency, covering an area of 210,495 km². Frequent flooding in the Alo Watershed has caused significant damage, with various contributing factors including high rainfall, low public awareness of environmental issues, and sparse vegetation cover. To assess the impact of land condition changes on river discharge in the Alo Watershed, the Hydrologic Engineering Centre - Hydrologic Modelling System (HEC – HMS) program was employed, utilizing the Soil Conservation. The analysis using HEC-HMS program revealed that the discharge under 2019 land use conditions was higher than that projected in the 2032 Regional Spatial Plan (RTRW). To reduce future discharge, land use management was simulated by decreasing certain land uses, which were reallocated to other types of use, while adhering to the 2032 RTRW guidelines. The simulation of land use management under Scenario 1, with a return period of T years, succeeded in reducing flood discharge by 8,65%-14,67% compared to the 2019 conditions. Scenario 2 achieved a reduction of 8,43%-14,70%. Both scenario effectively reduced flood discharge beyond the 2019 conditions, indicating the potential of these strategies to mitigate future flood risks.

Material is one of the most crucial resources in the construction implementation process. However, the occurrence of material waste not only fails to contribute added value to the project scope but can also lead to significant financial losses for the project implementer. This study aims to analyze the factors that cause material waste in the construction project of UPT BKN Gorontalo. The research focuses on several contributing aspects, including design, procurement, handling, implementation, residuals, and other unexpected factors, as well as efforts to minimize material waste. A combination of qualitative and quantitative approaches was employed, involving field surveys, participatory observations, secondary data analysis, and the distribution of questionnaires to contractors and consultants directly involved in the project. The data were then processed using SPSS software to determine the significance and strength of the influence of each variable. The results showed that among the seven variables analyzed, three had a significant effect on material waste: handling (X3), implementation (X4), and other factors (X6). Meanwhile, variables such as design, procurement, residuals, and minimizing material waste did not show a statistically significant effect. Furthermore, the correlation analysis indicated that the variable "other factors" had the strongest relationship with material waste, followed by implementation and handling. The findings of this research are expected to serve as a reference for improving material management in future construction projects to reduce waste and enhance efficiency.

The implementation of infrastructure development in Indonesia has grown rapidly in recent years, particularly in the context of its status as a developing country. One major project receiving attention in Gorontalo Province is the construction of the Bulango Ulu Dam. However, this project has faced delays in completion, which necessitates an in-depth analysis to optimize both time and cost. This study aims to analyze the project’s work network to identify the critical path and evaluate time and cost efficiency through the application of a crash program using additional overtime hours. The research was conducted at several project locations: Tulova Village, Owata Village, and Mongiilo Village in Bone Bolango Regency, Gorontalo Province. The study employed the crash program method and utilized Microsoft Project and Microsoft Excel for data processing. These tools supported the identification of critical tasks and the analysis of overtime productivity, crash duration, cost slope, and post-crash program time and cost efficiency. The analysis revealed that critical tasks in the Bulango Ulu Dam construction include drilling and grouting, stockpile work, dam top miscellaneous work, cleaning, and jetty trash boom installation. Time efficiency resulting from overtime additions was found to be: 10% (1 hour), 16.90% (2 hours), 22.62% (3 hours), 26.67% (4 hours), and 30% (5 hours). Meanwhile, cost efficiency peaked at 2.58% with 4 hours of overtime. These findings suggest that the optimal scenario for time and cost efficiency in hoarding work is achieved by adding 4 hours of overtime.

Fri, 27 Jun 2025 00:00:00 +0000

According to data from Statistics Indonesia, the Human Development Index (HDI) in 2022 reached 72.91, increasing from 72.29 in the previous year. Although Indonesia’s HDI continues to improve, disparities remain among provinces, indicating that HDI distribution is still uneven. Given the importance of HDI in aregion, it is necessary to conduct statistical analysis to identify the factors that significantly influence HDI using regression analysis. In applying multiple linear regression, several classical statistical assumptions must be met, one of which is the central focus of this analysis-addressing the issue of multicollinearity. Several methods have been identified to address multicollinearity, including Jackknife Ridge Regreesion (JRR) and Principal Component Regression (PCR). This study aims to compare the effectiveness of both methods in handling multicollinearity based on Adjusted R² and Mean Square Error (MSE) and to analyze the factors that significantly influence the HDI level in Indonesia. The data used in this study are secondary data comprising HDI and its related factors for each province in Indonesia in 2022, obtained from bps.go.id. Based on the analysis, the best model uses the JRR method, with an Adjusted R²value of 96.7% and MSE of 0.033.

The agricultural sector plays a crucial role in realizing Asta Cita's vision of food security, one of which is through the optimization of the Toraut Dam in Toraut Utara Village. However, increasing water demand for rice field intensification and expansion, alongside limited irrigation water supply, necessitates efficient irrigation system management. This research aims to analyze water loss in the distribution of irrigation networks in the Toraut Irrigation Area. The study used primary data (cross-sectional geometry and canal flow velocity measured using the surface buoy method) and secondary data (climatological records, irrigation network maps, and supporting documents). The analysis included calculating flow discharge, water loss due to evaporation using the Penman method, seepage, irrigation efficiency, and water loss in each channel segment. Results showed the highest discharge in the primary channel was at SPKr I upstream (5.586 m³/s), and the lowest was at SPKr 7 downstream (0.136 m³/s). In the secondary channel, the highest discharge was found at Secondary Tumpah upstream (0.895 m³/s), while the lowest was at Secondary Dumara downstream (0.043 m³/s). The highest efficiency in the primary channel was at SPKn (98.55%), while the lowest was at SPKr 6 (70.15%). In the secondary channels, the highest efficiency was at Secondary Tongot 2 (97.76%), and the lowest at Secondary Dumara (35.87%). The greatest water loss in the primary channel occurred at SPKr 6 (29.85%), and the least at SPKn (1.45%). For secondary channels, the greatest water loss occurred in Secondary Dumara (64.13%) and the least in Secondary Tondait (0.75%).

This study focuses on the analysis of the architectural section of the Maritime Integrated Laboratory Building Development Project, which constitutes a significant portion of the overall project cost. However, this section still has the potential for cost optimization through re-efficiency efforts. Therefore, the application of the Value Engineering (VE) method is necessary to identify and eliminate unnecessary costs and efforts, ultimately reducing the total value or cost of the project while maintaining its function and quality. The data required for this study include the Cost Budget Plan (Rencana Anggaran Biaya/RAB) and Unit Price Analysis (Analisa Harga Satuan Pekerjaan/AHSP). The research method consists of several stages: cost model analysis, breakdown of work items, Pareto analysis to identify high-cost contributors, creative development of design alternatives, and analytical decision-making using Life Cycle Cost (LCC) and the Analytical Hierarchy Process (AHP). Based on the VE analysis, it was found that the most significant cost-saving opportunities were in the wall and floor work components. After replacing the initial designs with the recommended alternatives, the total savings in construction costs reached Rp. 654,697,776.22 from the total architectural cost of Rp. 8,407,006,703.01, resulting in a savings percentage of 7.79%. Additionally, savings from the life cycle cost analysis amounted to Rp. 1,039,066,566.57. These results demonstrate that the Value Engineering approach is effective in achieving cost efficiency without compromising the functional integrity of the project.

Construction project delays are a critical issue frequently encountered during project implementation. These delays may result from various internal factors such as labor shortages, late material deliveries, and incomplete design plans, all of which directly impact the project completion schedule. The Fault Tree Analysis (FTA) method needs to be applied to the Amaris Extension Gorontalo project to identify and mitigate delay-causing factors that pose a risk to timely project completion. The FTA method is used to identify the root causes of project delays by analyzing the basic failure factors. Data were collected through observations, interviews, and project schedules. The analysis was conducted by constructing a fault tree. This study was carried out on the Amaris Extension Gorontalo project with a duration of 365 days. The results of the study indicate that delays were primarily caused by incomplete design planning, labor shortages, and issues related to materials and execution. The Fault Tree Analysis (FTA) method successfully identified the root causes and the top events with the highest probability of occurrence in weeks 19 and 20. These findings provide a solid foundation for improving future project management.
