Analysis of the Consumer Behavior of USU Faculty of Social and Political Sciences Students in Watching Culinary Content Shows Mukbang by YouTuber Tanboy Kun
No full textThis study aims to analyze the consumer behavior of students at the Faculty of Social and Political Sciences (FISIP) at the University of North Sumatra (USU) who watch culinary content featuring YouTuber Tanboy Kun, known as mukbang. The rise of mukbang content on YouTube is considered to influence student consumption patterns, particularly in encouraging impulsive and excessive food consumption. This is relevant considering that students are in their productive age, vulnerable to the influence of digital media, and supported by a campus environment with easy and diverse culinary access.This study employed a descriptive qualitative approach with a constructivist paradigm. Data collection techniques included in-depth interviews, observation, and documentation. Seven active students at the Faculty of Social and Political Sciences (FISIP) at USU, who are regular viewers and subscribers of Tanboy Kun's YouTube channel, were selected using purposive sampling. Additionally, one expert informant was interviewed for data triangulation to strengthen the validity of the research findings. Data analysis was conducted using Albert Bandura's Social Learning Theory, which encompasses the processes of attention, storage, behavioral reproduction, and motivation.The results of this study indicate that Tanboy Kun's mukbang program contributes to shaping students' consumer behavior, particularly through visual cues, eating expressions, and food portion sizes. This content triggers students' attention and interest, which is then stored in memory and manifested in the form of increased eating frequency, larger portion sizes, and a tendency to try similar foods. Environmental factors around campus also reinforce this consumer behavior. This research is expected to contribute to the study of communication science, particularly regarding the influence of digital media on student consumption behavior, as well as raising awareness of the importance of media literacy.162 PagesSkripsi Sarjan
Characterization of Static Mechanical Properties and Crack Patterns of Concrete Reinforced with Palm Oil Fuel Ash and Fly Ash
No full textThe utilization of Fly Ash and Palm Oil Fuel Ash (POFA) as alternative constituent materials for mortar represents a strategic solution to support sustainable construction concepts. This study aims to analyze the effects of Fly Ash and POFA addition on the physical properties, mechanical properties, crack patterns, and microstructural characteristics of mortar. An experimental design was employed using variations of Fly Ash (0% and 5%) and POFA (0%, 5%, 10%, and 15%) as cement replacement materials. Testing included slump flow, density, absorption, compressive strength, and splitting tensile strength at 28 days, supplemented by microstructural analysis using Scanning Electron Microscope - Energy Dispersive X-ray Spectroscopy (SEM-EDS). The results indicated that the combination of Fly Ash and POFA significantly enhanced mortar performance. The resulting densities ranged from 2,080.63 kg/m³ (M22) to 2,234.23 kg/m³ (M24). The optimum composition was achieved in the M24 variation (5% Fly Ash + 15% POFA), which yielded a maximum compressive strength of 50.67 MPa and a splitting tensile strength of 6.66 MPa, classifying it as high-strength concrete. Crack pattern analysis showed a transition in failure mechanisms from bond cracks in the control sample to shear cracks in the optimum sample. These findings were validated by microstructural analysis, which revealed a highly dense C-S-H matrix morphology dominated by Silica (≈56.7%) and Calcium (≈29.4%) compounds resulting from the pozzolanic reaction.113 PagesSkripsi Sarjan
Performance Analysis of Horticultural Cold Storage Using A 1 PK Split Air Conditioner
No full textThis study aims to analyze the performance of a horticultural cold storage
system using a 1 PK split air conditioner (AC) as a more economical cooling
alternative. The experiment was conducted at the Refrigeration Engineering
Laboratory, Department of Mechanical Engineering, Universitas Sumatera Utara,
using 5 kg of kangkung (water spinach) as the cooling load. The tests were carried out
under two conditions, namely without cooling load and with cooling load, while the
storage temperature was maintained within a range of 5–7 °C. The analyzed
parameters included compressor work, evaporator cooling capacity, electrical power
consumption, and coefficient of performance (COP). The cooling system used R32
refrigerant. The results show that the cold storage system using a 1 PK split AC was
able to achieve suitable storage temperatures for horticultural products and exhibited
satisfactory system performance. Therefore, the use of a 1 PK split AC is considered
feasible as an alternative cooling system for small- and medium-scale cold storage
applications.102 PagesSkripsi Sarjan
The Relationship Between The Level of Parental Knowledge About Cleft Lip and Palate and Delays in Referral to Hospitals in Medan
No full textCleft lip and palate (CLP) is a common congenital orofacial disorder that requires early correction to minimize its impact and optimize treatment success. However, delays in patient referral to a hospital or doctor are often caused by parents' lack of awareness and knowledge about the impact of CLP and the importance of early management, including the use of feeding plates as the initial treatment. This delay in referral can hinder the achievement of optimal functional and aesthetic benefits for patients. To determine the factors that influence the delay in CLP management, as well as the relationship between the level of parental knowledge (general about CLP and specifically about feeding plates) and the delay in referral. A cross-sectional analytical survey was conducted on 103 parents of CLP patients in two hospitals in Medan City. Data were collected using a questionnaire, with the independent variable being the level of parental knowledge and the dependent variable being the delay in referral. Most (70.8%) parents had a moderate level of knowledge. There was a significant relationship (P=0.019) between the level of knowledge and referral delay. Patients with poor knowledge experienced a higher referral delay (77.8%) compared to those with good knowledge (38.1%). The level of parental knowledge is a factor that greatly influences the delay in referral/management of CLP diagnosis. There was a significant relationship between the level of parental knowledge, both regarding CLP and feeding plates, and referral delay (P<0.05).92 PagesSkripsi Sarjan
Juridical Review of the Use of Diplomatic Channels in Maritime Boundary Disputes between Indonesia and Timor Leste
No full textThe maritime boundary dispute between Indonesia and Timor-Leste constitutes a problem of maritime delimitation. Efforts to address this dispute may be pursued through peaceful diplomacy, prioritizing negotiation, mediation, and conciliation as means to achieve mutually beneficial solutions. This study aims to analyze the settlement of the dispute from the perspective of international law. Specifically, the research examines the regulation of maritime dispute settlement through diplomatic channels, the international legal perspective on the maritime boundary dispute between Indonesia and Timor-Leste, and the mechanisms for the use of diplomatic approaches in resolving the maritime boundary dispute between Indonesia and Timor-Leste under international law.
This research employs a normative legal research method using a statute approach. The data are derived from primary legal materials such as the Convention, and Law and Regulation. Secondary data were obtained from literature, journals, and official documents, while data collection was conducted through library research and qualitative analysis of relevant international legal norms and principles.
The findings indicate that The settlement of maritime boundary disputes between Indonesia and Timor-Leste primarily relies on peaceful diplomacy approaches as mandated by the United Nations Charter and UNCLOS 1982, with bilateral negotiations serving as the main avenue for determining the territorial sea, Exclusive Economic Zone, and continental shelf boundaries. Both countries prioritize direct dialogue based on the median line and equitable solution principles while taking into account relevant geographical factors and complex historical backgrounds. This diplomacy process is supported by joint technical forums such as the Joint Border Committee and the Technical Sub-Committee on Border Demarcation and Regulation, which analyze geospatial data and formulate provisional arrangements to prevent conflict. Throughout the process, both states must refrain from unilateral actions and negotiate in good faith, reflecting a diplomacy commitment to the peaceful settlement of disputes. If negotiations reach an impasse, diplomacy mechanisms may continue through mediation, conciliation, or international arbitration, ensuring that the resolution remains rooted in constructive dialogue and cooperation.

No full textThe Indonesian government, through the Ministry of Women’s Empowerment and Child
Protection (KPPPA), has developed the Child-Friendly City (CFC) policy as an effort to
create a safe, inclusive, and supportive environment for children’s growth and development.
The indicators of a Child-Friendly City are divided into five clusters, one of which is the
special protection cluster. Medan City is one of the regions designated as a pilot project for
the Child-Friendly City program, considering its status as one of the largest cities in
Indonesia with a high child population.
This study aims to analyze the effectiveness of the Child-Friendly City policy within the
special protection cluster in Medan City, as well as to identify the supporting and inhibiting
factors in its implementation. This research employs a qualitative method, with data analysis
techniques consisting of data reduction, data display, and conclusion drawing.
The findings indicate that the implementation of the Child-Friendly City policy in the special
protection cluster in Medan City has not yet been effective, particularly in terms of
appropriate implementation, appropriate targeting, appropriate environment, and appropriate
process. However, the indicator of appropriate policy has been considered fulfilled.
Supporting factors in the implementation of this policy include the local government’s
commitment to policy evaluation, stakeholder involvement, and the implementation of
development planning meetings (Musrenbang) as a means of community participation.

and the absence of integrated data on children requiring special protection.150 PagesTesis Magiste
The Analysis of the Effect of Consumer Characteristics on the Purchase of SPHP Rice by Bulog in Medan
No full textThis study aims to analyze the influence of consumer characteristics on the
percentage of SPHP rice (Stabilization of Food Supply and Prices) consumption
distributed by Perum BULOG in Medan City. The analyzed characteristics
include household income, education level, gender and number of dependents.
The analytical method used in this research is Tobit regression. Primary data were
collected through questionnaires distributed to 60 respondents who are consumers
or former consumers of SPHP rice. Secondary data were obtained from relevant
agencies such as Perum BULOG, the National Food Agency, and the Central
Statistics Agency. The results show that income and education have a negative
and significant effect on the percentage of SPHP rice consumption, while gender
and the number of dependents has no significant effect. These findings indicate
that consumers with higher income and education levels tend to consume SPHP
rice in smaller proportions.
This research contributes to the understanding of SPHP rice consumer
segmentation and can serve as a reference for the government and Perum BULOG
in designing more targeted distribution and outreach strategies, thereby enhancing
the effectiveness of the SPHP program as part of national food security
strengthening efforts.77 PagesSkripsi Sarjan
Comparative Study of Random Forest and Elastic Net Logistic Regression in Classifying Patient Discharge Status at BPJS Kesehatan Primary Healthcare Facilities: An Evaluation Based on F1-Score, PR AUC, and Brier Score
No full textThis study analyzes and compares the performance of Random Forest and Elastic Net Logistic Regression (SAGA solver) for classifying patient discharge status at BPJS Kesehatan Primary Care Facilities (FKTP). The dataset is large-scale, contains exclusively nominal predictors, and exhibits class imbalance (approximately 64.9% majority class). The experimental design employs an 80%/20% train–test split, one-hot encoding for preprocessing, and class balancing on the training data via random undersampling. Hyperparameter tuning is conducted using a staged coarse-to-fine search with local-optimum convergence criteria (improvement threshold ε = 10^(−6) and patience = 10), followed by 10-fold cross-validation for internal evaluation and final assessment on the test set. The primary evaluation metrics are F1-Score, Precision–Recall AUC (PR AUC), and Brier Score. On the test set, both methods achieve identical F1-Scores and nearly identical PR-AUC values. Random Forest and Elastic Net Logistic Regression both attain F1 = 0.996679, with PR-AUC = 0.999931 for Random Forest and 0.999927 for Elastic Net Logistic Regression. A more interpretable difference is observed in probability calibration, where Elastic Net Logistic Regression yields a lower Brier Score (0.002016) compared to Random Forest (0.002706). These results indicate that while both models lie on the same performance plateau in terms of discrimination and ranking, Elastic Net Logistic Regression provides better-calibrated probability estimates.144 PagesSkripsi Sarjan
