Utilization of the Mangrove Ecosystem for the Welfare of the Community in Kuala Langsa Village, Langsa Barat District, Langsa City
No full textThis study aims to examine the utilization of the mangrove ecosystem in improving the welfare of the community in Kuala Langsa Village, Langsa Barat District, Langsa City. The research employs a descriptive qualitative method with data collected through observation, in-depth interviews, and documentation. The findings show that the mangrove ecosystem is utilized in two main forms: direct use through the processing of derivative products (such as syrup, jam, dodol, and crackers) and the development of the Langsa Mangrove Forest ecotourism, which stimulates supporting economic activities (such as food stalls). This utilization significantly contributes to increasing community income, creating business opportunities for local micro, small, and medium enterprises (MSMEs), and strengthening collective awareness of the importance of environmental conservation. The main challenges faced include limited technology and skills in processing mangrove products into higher-value commodities. This study recommends enhancing training programs, strengthening government support, and improving market access as strategies for sustainable mangrove management to promote community welfare.179 PagesSkripsi Sarjan
Determinants Of Income Inequality in BRICS Countries: a Macroeconomic Perspective
No full textIncome inequality remains a structural issue in developing economies,
including BRICS countries (Brazil, Russia, India, China, and South Africa). Despite
their strong economic growth, these nations continue to experience uneven income
distribution. This study examines the macroeconomic determinants of income
inequality in BRICS countries during the 1993–2022 period. The dependent
variable is income inequality measured by the Gini Index, while the independent
variables include economic growth, urbanization, inflation, and the Human
Development Index (HDI).
The study employs secondary panel data obtained from the World Bank and
UNDP. The analysis is conducted using panel data regression with the Fixed Effect
Model (FEM), selected based on the Chow, Hausman, and Lagrange Multiplier
tests.
The results show that economic growth and HDI have a significant negative
effect on income inequality, while urbanization and inflation have a significant
positive effect. Simultaneously, all independent variables significantly influence
income inequality in BRICS countries. These findings highlight the importance of
inclusive economic policies, inflation control, and equitable human development to
reduce income disparities within the BRICS economies.98 PagesSkripsi Sarjan
The Effect of Shape and Storage Duration on Moisture Content, Crude Protein, Crude Fat, Fungus Percentage, and Insect Infestation of Black Soldier Fly Larvae Products
No full textThis study aims to determine the effect of form and storage duration on moisture content, crude protein, crude fat, fungal percentage, and insect infestation of Black Soldier Fly (BSF) larvae products. The research was conducted at the Laboratory of Animal Feed Science and Technology, Faculty of Agriculture, University of North Sumatra. The research design used was a completely randomized design (CRD) with a 3x3 factorial pattern and 3 replications. Factor A was feed form (mash, crumble, and pellet) and factor B was storage duration (0, 4, and 8 weeks). The results showed that feed form and storage duration had a significant effect (P0.05) the percentage of mold and insect infestation. Overall, the pellet form was the best treatment because it was able to maintain low moisture content (8.58%), maintain the stability of crude protein (20.00%) and crude fat (10.89%), and was free from fungi and insects during storage. It can be concluded that the pellet form is recommended as the most storable form of BSF larvae and suitable for use as livestock feed.74 pagesSkripsi Sarjan
Analysis of Respiratory Rate, Morphological and Histopathological Changes in the Lungs of Wistar Rats Following Graded Formalin Inhalation
No full textIntroduction: Formaldehyde is a colorless organic compound with a pungent odor and is one of the most common indoor air pollutants. Exposure to formaldehyde gas can cause various respiratory issues and can lead to serious health problems. Objective: This study aimed to assess the effects of formalin inhalation on respiratory rate, as well as the macroscopic and microscopic structures of the lungs in Wistar rats. Methods: This experimental study used 24 Wistar rats divided into one control group and three experimental groups, each exposed to different concentrations of formalin vapor for 8 hours per day over a 30-day period. Respiratory rate was analyzed using the chi-square test, while lung weight and size were analyzed using one-way ANOVA. Results and Discussion: Although formalin inhalation had no significant effect on the respiratory rate of rats, morphological changes were observed in the lungs, including congestion, hyperemia, and an increase in lung weight and size. Histological examination revealed thickening of the alveolar walls, atelectasis, enlargement of bronchus-associated lymphoid tissue (BALT), as well as fibrosis and necrosis in lung tissue. Conclusion: This study demonstrates that formalin inhalation caused significant lung tissue damage through inflammatory processes that ultimately led to lung injury and pulmonary fibrosis.74 PagesSkripsi Sarjan
Spatial Analysis of The Incidence of Drug Resistant Tuberculosis in Medan City in 2024
No full textThe inability of first-line anti-tuberculosis drugs to kill Mycobacterium tuberculosis is a sign of drug-resistant tuberculosis, which over time can lead to treatment failure, increased transmission, and a heavier burden on public health. Based on WHO data, Indonesia ranks third in the world with a burden of 7.4% of the estimated 400,000 cases of drug-resistant tuberculosis globally per year. The burden of drug-resistant tuberculosis in North Sumatra Province is 7.9 percent. At the local level, the incidence of drug-resistant tuberculosis in the city of Medan remains a significant public health problem. Various studies have discussed the risk factors for drug-resistant tuberculosis and prevention efforts. However, there is still little information on the incidence of drug-resistant tuberculosis reviewed in terms of risk factors using a spatial analysis approach. The purpose of this study was to describe the spatial distribution of drug-resistant tuberculosis in Medan City in 2024. This study used a GIS and descriptive quantitative approach. The sample in this study was all cases of drug-resistant tuberculosis with secondary data from the Health Office in 2024 in Medan City. The data analysis used was spatial. The results of the spatial analysis of drug-resistant tuberculosis cases showed that the subdistricts included in the very high category were Medan Labuhan (9.27%), Medan Selayang (7.32%), and Medan Belawan (6.83%). The contributing factors that were consistent with the spatial pattern of drug-resistant tuberculosis cases were age, gender, and previous history of tuberculosis treatment. It is recommended that the Medan City Government collaborate with the Health Office to strengthen interventions for drug-resistant tuberculosis through increased case detection, contact tracing, social sensitivity-based education, and diabetes mellitus screening in patients with drug-resistant tuberculosis.108 PagesSkripsi Sarjan
Analysis of Near Misses Using Smart Online Applications on Palm Oilharvesters in Rantauprapat Estate in 2025
No full textAccident prevention can be learned from accidents themselves and near misses.
Human factors arise from the negligence of the workers themselves. The purpose
of this research is to understand near miss incidents based on time, coordinates,
cause and effect, to identify individual characteristics such as age and gender, to
map the occurrences of near misses and work accidents, and to identify near
misses experienced by oil palm harvesting workers. The type of research

The Role of the Tebing Tinggi Cooperative Trade and SME Service in the Development of Lemang Micro, Small and Medium Enterprises (MSMEs) Due to the Construction of the Trans Sumatera Toll Road
No full textThe development of large-scale infrastructure such as the Trans-Sumatra Toll Road has had a significant impact on local economic sectors, particularly Micro, Small, and Medium Enterprises (MSMEs). One of the affected sectors is the lemang MSMEs in Tebing Tinggi City, which have experienced a decline in both the number of stalls and sales due to changes in traffic patterns that previously supported their business locations. This condition highlights the crucial role of local government, especially the Office of Trade, Cooperatives, and MSMEs of Tebing Tinggi City, in providing protection and adaptive strategies to ensure the sustainability of MSMEs amidst such transitions.
This study aims to analyze the role of the Office of Trade, Cooperatives, and MSMEs in the development of lemang MSMEs following the operation of the Trans-Sumatra Toll Road. The research uses a descriptive method with a qualitative approach, employing data collection techniques such as interviews, observation, and documentation. The theoretical framework is based on organizational behavior theory by Robbins (2001), which includes five indicators: motivation, leadership, communication, organizational culture, and decision- making. Informants in this study include the Head of the Cooperatives and Micro Enterprises Division, the Head of the Trade Division, lemang MSME entrepreneurs, and the general public.
The results show that the role of the Office of Trade, Cooperatives, and MSMEs in supporting the sustainability of lemang MSMEs has not been optimal. Government motivation and support remain limited; leadership lacks consistent strategic direction; communication does not effectively reach all MSME actors; and decision-making tends to be top-down and non-participatory. Therefore, a more responsive and comprehensive strategy is needed to ensure the resilience and growth of MSMEs in response to infrastructure development.128 PagesSkripsi Sarjan
Factors Associated with Musculoskeletal Disorders Complaints Among Sales Promotion Girls (SPG) at Matahari Department Store Thamrin Plaza Medan
No full textSales Promotion Girls (SPGs) play a vital role in the retail sector; however, their job, which requires prolonged standing and repetitive tasks, poses a risk for musculoskeletal disorders (MSDs). This study aims to identify the factors associated with MSD complaints among SPGs at Matahari Department Store Thamrin Plaza Medan. This research used a quantitative design with a cross- sectional approach. A total of 100 respondents were selected using simple random sampling. Data were collected through the Nordic Body Map questionnaire, interviews, and direct measurements of body weight and height. Bivariate analysis was performed using the Spearman test. The results showed a significant relationship between age (p < 0.001) and years of service (p < 0.001) with MSD complaints. The older and the longer a respondent had worked, the higher the reported MSD complaints. On the other hand, there was no significant relationship between Body Mass Index (BMI) (p = 0.666) and lifestyle (p = 0.135) with MSD complaints. The study concludes that age and years of service are significantly associated with MSD complaints, whereas BMI and lifestyle do not show a meaningful relationship137 PagesSkripsi Sarjan
The Impact of Macroeconomic Dynamics on Economic Growth in Developing G20 Member Countries
No full textEconomic growth in developing G20 member countries is increasingly influenced by global and domestic macroeconomic dynamics, particularly commodity price volatility, uncertainty in international financial markets, and fluctuations in monetary policies of advanced economies. This study aims to analyze the effects of inflation, interest rates, exchange rates, foreign direct investment (FDI), and government expenditure on economic growth in both the long run and the short run. The study employs annual panel data from nine developing G20 member countries over the period 2000–2023. The Panel Autoregressive Distributed Lag (Panel ARDL) method with the Pooled Mean Group (PMG) approach is applied to accommodate cross-country heterogeneity while maintaining consistency in long-run estimations. The long-run estimation results indicate that inflation has a positive and significant effect on economic growth, while interest rates have a significant negative effect. FDI is found to have a significant positive impact, as is government expenditure, which acts as a driving factor for long-term economic growth. In contrast, exchange rates do not exhibit a significant long-run effect. In the short run, only government expenditure shows a significant effect on economic growth, although at a relatively weak level of significance. Meanwhile, inflation, interest rates, exchange rates, and FDI do not demonstrate significant short-run effects. The presence of a significant error correction mechanism indicates a rapid adjustment process from short-run conditions toward long-run equilibrium. These findings emphasize that inflation stabilization, credible interest rate management, and the optimization of FDI inflows are key elements in supporting long-term economic growth in developing G20 member countries. Furthermore, the effectiveness of government expenditure serves as an important instrument both as a long-term growth driver and as a short-term economic stimulus. This study provides empirical contributions to the literature on open macroeconomics and serves as a reference for policymakers in formulating more adaptive and sustainable monetary and fiscal strategies.137 PagesTesis Magiste
