Implementation Of The IndoBERT Method For Emotion Analysis On User Reviews Of The M-Paspor Application
No full textThe M-Paspor application serves as an essential digital platform for managing passport services online, making user reviews on the Google Play Store a valuable source for understanding public experiences with the system. These reviews contain various emotional expressions, ranging from appreciation to technical complaints, which require an artificial intelligence approach for effective analysis. This study employs the IndoBERT model due to its strong capability in interpreting Indonesian linguistic context through Deep learning methods. The research process includes collecting 2,996 user reviews, performing text cleaning and normalization, assigning initial sentiment labels using the Inset lexicon followed by manual verification, splitting the dataset, and fine-tuning IndoBERT with a maximum input length of 63 tokens. Evaluation on 446 test samples shows that IndoBERT achieves an accuracy of 86% and a macro F1-score of 0.61, demonstrating strong performance on positive and negative sentiment classes. This study concludes that IndoBERT is effective in identifying user emotions, although the neutral class remains challenging due to its limited representation and more ambiguous linguistic patterns. The findings also indicate inconsistencies between star ratings and textual sentiment in several reviews, suggesting that text-based analysis provides a more representative understanding of user perceptions toward the M-Paspor service.73 PagesSkripsi Sarjan

No full textThis study aims to determine the characteristics of F4 generation corn
plants resulting from F3 free crossing, which are expected to be useful as a genetic
source for forming a new base population as selection material for developing
desired varieties. The study was conducted at Jalan Pasar 1 No. 296 Tanjung Sari,
Medan Selayang District, from March to June 2025 using descriptive statistical
analysis methods. The corn seeds used were pre-mixed seeds taken at random. The
parameters observed were plant height, stem diameter, number of leaves, male
flowering age, female flowering age, difference in male and female flowering age,
male flower color, female flower color, stem color, and stem hair color. The results
showed that the phenotypic variance values had diverse or broad criteria for the
characteristics of plant height, number of leaves, stem diameter, male flowering
age, and female flowering age. Qualitative observations of male flower color and
variations between observations were green and greenish purple, while female
flowers varied in color between green and brown. Qualitative observation
characteristics for stem color showed color variations, namely green and purple.

only one color, namely white.62 PagesSkripsi Sarjan
Penalty Kick Direction Prediction Based on Kicker’s Pose Estimation and Run Up Sequence using LSTM and 1D Convolutional Neural Network (1D CNN)
No full textPenalty kicks are decisive moments that can determine football match outcomes. For goalkeepers, the ability to read kick direction before the ball is struck provides an invaluable advantage. This research develops a penalty kick direction prediction system as a goalkeeper training tool by analyzing the kicker's body movements during the run-up phase. The system employs 3D pose estimation from 429 penalty kick videos and a hybrid 1D CNN-LSTM architecture that combines frame-level spatial pattern analysis with overall movement dynamics understanding. The development process faced significant challenges, particularly limited dataset size and inherent ambiguity in center-directed kicks. Ablation study revealed that the hybrid architecture achieved 52.33% accuracy, improving 11.63% over spatial-only models. A key finding is that temporal component is approximately 2.5 times more critical than spatial component confirming that "how the kicker moves toward the ball" is more informative than "body position at any single moment". While accuracy has not yet reached ideal levels for direct implementation, this research provides scientific and technical foundations for developing computer vision-based goalkeeper training tools, and opens future research directions through integration of additional visual information such as ball trajectory and field context.90 PagesSkripsi Sarjan
Legal Implications of Changes in Foundation Structure Due to the Death of the Chairperson of the Board of Trustees (A Juridical Analysis of Supreme Court Decision No. 3295 K/Pdt/2024)
No full textThe death of the Chairperson of the Board of Trustees in a foundation gives rise to complex legal issues, particularly concerning the mechanism for filling vacancies and the validity of changes in the organizational structure. Problems arise when one remaining member of the Board of Trustees refuses to attend trustees' meetings and even declares unwillingness to be involved in the foundation's structure, yet is not prepared to resign formally. The issues examined in this study concern the authority of a sole trustee to replace or appoint additional members of the board of trustees, management, and supervisors within a foundation; the validity of a trustees' meeting attended by only one trustee in the absence of other trustees following the death of the Chairperson of the Board of Trustees; and the considerations of the judges in adjudicating disputes over changes in the structure of the Board of Trustees resulting from the death of the Chairperson, as reflected in Supreme Court Decision Number 3295 K/Pdt/2024.
This research constitutes normative juridical legal research with a descriptive- analytical character. The approaches employed include a statutory approach, a case approach through an examination of Supreme Court Decision Number 3295 K/Pdt/2024, and a conceptual approach. The data source consists of secondary data obtained through library research, which are then analyzed qualitatively using deductive reasoning.
The results of the study indicate that a sole trustee has full authority to appoint and dismiss the management and supervisors of the foundation, but faces limitations in appointing or replacing other members of the Board of Trustees, which generally requires a joint meeting mechanism involving the management and supervisors. A trustees' meeting convened by only one trustee without fulfilling the quorum requirement is deemed invalid if there are still other active members of the Board of Trustees, except in circumstances where the foundation has only a sole trustee. In Decision No. 3295 K/Pdt/2024, the Supreme Court adopted a strict formalistic approach by declaring the meeting invalid on the grounds that another trustee still formally held trustee status and had not been officially dismissed, despite the factual refusal to participate in the foundation's structure. The Supreme Court annulled all deeds concerning changes to the foundation's structure; however, the decision does not provide a comprehensive legal solution regarding settlement mechanisms, the protection of good-faith third parties, or public interests, considering that the foundation manages various educational institutions.135 PagesTesis Magiste

No full textThis study was conducted to determine the types of rats and their ectoparasites,
the relative density (trap success) of rats, the specific flea index (SFI), the prevalence,
and the intensity of ectoparasite infestation in the densely populated residential area
of Mesjid Village, Medan Kota District, Medan City, North Sumatra. The study was
conducted in August 2025 at three locations with different environmental
characteristics, namely flood-prone areas, non-flood-prone areas with accumulated
waste, and shopping areas. The method used was a cross-sectional approach by
installing traps in 10 houses per location. A total of 20 single live traps were set up,
one trap outside the house and one trap outside the house, for 4 consecutive days. The
captured rats were identified by species and ectoparasites at the Medan Community
Laboratory Center (BLKM). The results showed that the rat species caught were
Rattus novergicus, Rattus tanezumi, and Suncus murinus (Insectivora). The highest
relative density (trap success) was found in environments 2 and 3, with values of
11.25% each. Three types of ectoparasites were found on the captured rats, namely
Laelaps sp. mites, Xenopsylla cheopis fleas, and Dermacentor sp. ticks. The highest
prevalence was found in Laelaps sp. in environments 2 and 4 on R. tanezumi, each
with a value of 100%. The highest intensity was found in environment 3, as well as.
The relationship between the specific flea index (IPK) of X. cheopis and the prevalence
and intensity of X. cheopis is inversely proportional.60 PagesSkripsi Sarjan

Innovative Design and Development of a Transmission System for a Used Infusion Bottle Recycling Device as a Filament Source for 3D Printers Using The Pultrusion Method with a Compact Design
No full textThis study develops an innovative design and construction of a transmission system for a recycling device that processes used infusion bottles made of Low Density Polyethylene (LDPE) into a filament source for 3D printers using the pultrusion method, featuring a more compact and user-friendly design. Waste infusion bottles, classified as medical plastic waste, are produced in high volumes and pose a risk of environmental pollution if not properly managed. The reutilization of LDPE waste as a raw material for filament production represents an economical and environmentally friendly alternative solution.The device design process includes the development of a heating system, a filament pulling mechanism based on a gear transmission system, and temperature and pulling speed control using a stepper motor with an integrated control display. Testing was conducted with variations in raw material strip width (10 mm, 12 mm, and 14 mm) and forming temperature (100°C, 110°C, 120°C, and 130°C).The test results indicate that a combination of a 14 mm strip width and a temperature of 100°C produces the best filament quality, characterized by the most solid structure and minimal voids. With a raw material length of 20 cm, the device is capable of producing filament with a length of 106 cm within 40 seconds. Technical calculations show that the pulling torque reaches 563.38 Nm with a gear ratio of 1:7 and a pulling speed of 5 mm/s.Overall, the pultrusion-based recycling device has proven effective in processing LDPE waste into 3D printer filament and demonstrates strong potential for development as a solution to reduce plastic waste while providing a more sustainable raw material for 3D printing.78 PagesSkripsi Sarjan

No full textRAFAEL LAURENCIUS PANJAITAN, The Growth and Yield Response of Several Cowpea (Vigna unguiculata L. Walp) Varieties to the Application of Oyster Mushroom Baglog Waste Compost (under the supervision of YAYA HASANAH).
The low yield of cowpea is caused by climatic conditions and a lack of knowledge regarding the potential of cowpea cultivation in Indonesia. This study aimed to determine the growth and yield response of several cowpea varieties to the application of oyster mushroom baglog waste compost. Completely conducted on a research field using a factorial Randomized Block Design (RBD) with two factors, namely compost dosage (0, 7.5, 15, and 22.5 tons/ha) and cowpea varieties (Albina, Arghavan, and Tampi), each with three replications. The parameter observed included plant height, number of leaves, flowering age, harvest age, number of filled pods per sample, number of empty pods per plant, pod length, number of seeds per pod, seed weight per pod, seed weight per sample plant, seed weight per plot, 100-seed weight, and harvest index. The results showed that the Arghavan variety produced the best performance compared to the Albina and Tampi varieties. The application of oyster mushroom baglog waste compost had no significant effect on all observed variables. The interaction between compost dosage and variety also had no significant effect on all measured parameters.87 PagesSkripsi Sarjan
The Effectiveness of 2% Red Palm Oil (Elaeis guineensis Jacq.) Nanoemulgel on the Number of Osteoblast Cells after Tooth Extraction in Wistar Rats (Rattus norvegicus)
No full textAfter tooth extraction, a physiological wound healing process occurs, which includes four phases: hemostasis, inflammation, proliferation, and remodeling. Osteoblasts are one of the cells that play a role in bone formation during the proliferation and remodeling phases of alveolar bone after tooth extraction. Delayed wound healing can lead to complications, so treatment that can accelerate wound healing is needed. A natural ingredient that can be used to accelerate wound healing is red palm oil. Red palm oil has the potential to heal wounds by accelerating wound closure. Research on the effect of red palm oil nanoemulgel on osteoblast numbers in wounds after tooth extraction is still very limited. This study aims to investigate the effectiveness of red palm oil (Elaeis guineensis Jacq.) nanoemulgel on osteoblast cells after tooth extraction in Wistar rats (Rattus norvegicus). This study is a laboratory experimental study using 9 treatment groups observed on days 7, 14, and 28. The results of the study were calculated using residual socket volume (RSV) and mean cell count of osteoblasts. Based on the Kruskal Wallis test, there was a significant difference in the mean RSV between the groups on days 7, 14, and 28 (p<0.05). Based on the One-way ANOVA test, there was a significant difference in the mean osteoblast cell count between the 14th and 28th day groups (p<0.05).109 PagesSkripsi Sarjan
