Abstract

A Barbershop service provider is a company that provides hair care to the community. Many people are currently doing business in this field, and many business actors are opening Barbershops in a variety of locations, ranging from campuses to office districts to densely populated towns. In Lhokseumawe City, there are 12 Barbershops. The application's benefit is that it can identify the shortest path from the user's location to the selected Barbershop, as well as the Barbershop's location and a brief description of the Barbershops in Lhokseumawe City. Only the system's defined nodes can be used to find the fastest route to the Barbershop. Dijkstra's method was chosen because it works against all current alternative functions and provides the shortest path from all nodes, ensuring that the shortest path is produced optimally. Because the Bellman-Ford algorithm is a variant of the BFS (best-first-search) algorithm, which is also employed in the search for the closest distance when the search for the closest distance has a negative weight, it was chosen. The same results were obtained in picking the route based on the results of the route selection test. However, when the two techniques are compared in terms of program execution time, Dijkstra's algorithm is faster than the Bellman-Ford algorithm.

Abstract

Korosi merupakan fenomena yang sering terjadi pada komponen dan peralatan industri. Proses penanganan korosi salah satunya adalah dengan menggunakan blasting. CV Mitra Blastida Utama merupakan salah satu perusahaan blasting yang cukup baik untuk membantu mitranya dalam menghadapi korosi. Kemampuan dalam melakukan blasting setelah didapatkan oleh perusahaan tersebut sejak lama. Namun prinsip blasting Yang digunakan untuk mengendalikan polusi belum sepenuhnya dipahami oleh karyawan perusahaan tersebut. Kegiatan penyuluhan pengendalian korosi pada pipa merupakan kegiatan memberikan dasar-dasar pengendalian korosi dan blasting pada mitra. Metode yang digunakan dalam kegiatan ini adalah metode penyuluhan. Pemahaman pengendalian korosi pada pipa mengalami peningkatan dari mulai sebelum penyuluhan sampai setelah dilakukan penyuluhan. Metode tersebut yang memudahkan peningkatan pemahaman peserta sebelum penyuluhan sampai sesudah penyuluhan.

Abstract

Air quality is one of the important aspects in maintaining environmental balance and public health. Increasing air quality in the environment is a matter of concern. Therefore, a method that can predict the Air Quality Index (AQI) effectively is needed to be able to monitor and support decision making on environmental impacts. This study aims to predict the Air Quality Index in Banda Aceh City using the Support Vector Regression algorithm, with five main parameters used in the study, namely particulate matter , Sulfur dioxide, Nitrogen dioxide, Carbon monoxide , and Ozone . In this research, the Support Vector Regression algorithm was chosen because of its ability to handle non-linear data and also because it can provide accurate predictions on data. The prediction system designed will be web-based using the flask framework and MySQL database, while the Support Vector Regression modeling will be done on google colab for the media used. In the process of modeling the data will be divided into 80% training data and 20% test data to ensure the model can capture long and short-term patterns. The results of the prediction will be compared using the Root Mean Squarred Error (RMSE) and Mean Squarred Error (MSE) evaluation metrics. The results of the evaluation using both metrics yielded RMSE values of 1.9001 and MSE of 3.6015. These values indicate good performance of the model in predicting the data. This research is expected to provide insight for future similar research in terms of prediction using the Support Vector Regression algorithm.

Abstract

This study focuses on the application of the Support Vector Machine (SVM) algorithm for classifying recipients who are eligible to receive Direct Cash Assistance from the Village Fund (BLT-DD) in Nurussalam District, East Aceh Regency. The background of this research is the difficulty in identifying households eligible for BLT-DD due to increasing poverty and economic inequality exacerbated by the COVID-19 pandemic. This study aims to address this issue by utilizing the SVM algorithm, which can separate household data into two categories: "Eligible" and "Not Eligible." A total of 550 data points from Nurussalam District were used in this study, with 400 data points for training and 150 data points for testing. In the training data, 322 households (80.5%) were classified as "Eligible," while 78 households (19.5%) were categorized as "Not Eligible." The data collected includes variables such as household income, type of employment, education level, history of chronic disease, and home ownership status. After preprocessing the data, such as normalization and encoding, the SVM model was trained to classify BLT-DD recipients. In the testing data, 128 data points (85.33%) were classified as "Eligible," while 22 data points (14.67%) were classified as "Not Eligible." Further analysis of village distribution in Nurussalam District shows that some villages have a high percentage of eligible recipients, such as Blang Rambong and Alue Jagat, with 100% of recipients classified as "Eligible." Other villages, such as Arul Pinang and Alue Dua Muka O, show more varied eligibility rates, with 71.43% and 72.73% classified as "Eligible," respectively. In conclusion, the SVM algorithm provides an effective approach in determining the eligibility of BLT-DD recipients, helping the government to distribute assistance more accurately and efficiently in Nurussalam District.

Abstract

This study aims to analyze and compare the performance of the K-Means and K-Medoids algorithms in clustering Cookpad application user reviews obtained directly from the Google Play Store. A total of 15,330 reviews were collected as a representation of authentic user opinions. The review text was first processed through a pre-processing stage, then converted into a numeric representation using the TF-IDF method. The clustering process was carried out using the K-Means and K-Medoids algorithms, which were then evaluated using the Silhouette Score metric, both on the original data and after removing outliers with the DBSCAN algorithm. The results showed that K-Medoids performed better with a score of 0.2788 (with outliers) and 0.2966 (without outliers), compared to K-Means which obtained a score of 0.2625 (with outliers) and 0.2795 (without outliers). The clusters formed were dominated by positive reviews with words such as "cook", "help", and "recipe", which describe user satisfaction. This study provides a systematic approach to analyzing Google Play app reviews by directly comparing two clustering algorithms and integrating outlier evaluation to improve the quality of cluster results. The limitation is that the data only comes from one platform. The results are visualized through an interactive web interface and are expected to be input in developing application features based on user needs.

Abstract

Communication is a way for humans to convey information, ideas, thoughts, feelings, or massages verbally or nonverbally. People with hearing impairments use expressions and symbols due to hearing limitations, the term tuna means less and rungu means hearing. To bridge communication, sign language translation through the development of systems such as text-to-speech can help improve accessibility between people with hearing impairments and spoken language users in various contexts of everyday life. The Indonesian Sign Language (SIBI) translation system in this study was built the waterfall research method in which each process will be carried out in stages and sequentially, starting from problem analysis and creating a conceptual system in order to strengthen the theorectical foundation and answer the formulation of the problems raised, this study uses the Keras deep learning model and the Convolutional Neural Network (CNN) approach. The test results show that the system is able to classify hand gestures and convert them into text and voice, in addition to the average respone time of less than one second, which is around 104 miliseconds per step. This shows that the system can operate in real-time with a fast and consistent response. Video transcription and voice synthesis for an Indonesian sign language translation system using the Python programming language were successfully implemented, supported by various libraries such as OpenCV, CVZone, and GTTS (Google Text-To-Speech). Testing results on 15 movement classes with 150 trials showed an average movement classification accuracy of 87%. Further research is recommended to increase the number of subjects and dataset diversity to improve the model’s generalizability.
