Abstract

Object detection models are pivotal for retail automation but require vast annotated datasets, which are costly and time-consuming to acquire. This creates a significant challenge in few-shot learning scenarios where data is scarce, leading to models with poor generalization. This study investigates strategies to overcome data limitations by training a YOLOv8 object detection model on a custom dataset of 152 retail product images across 28 classes. We conduct a comparative analysis of three training protocols: (1) a baseline model trained on the original data, (2) a model enhanced with advanced data augmentation techniques, and (3) a model supplemented with synthetically generated data. Performance is evaluated using mean Average Precision (mAP@50−95), Precision, and Recall. The synthetic data approach significantly outperformed the other methods, achieving the highest mAP@50−95 of 0.699 and the highest Recall of 0.856. While the data augmentation model yielded the highest Precision (0.875), its lower Recall (0.714) resulted in a suboptimal mAP. Furthermore, training with synthetic data demonstrated markedly faster and more stable convergence. Our findings indicate that for few-shot object detection in specialized domains like retail, supplementing training with synthetic data is a more effective strategy than relying solely on traditional augmentation.

Abstract

The rapid development of information technology has created a strong demand for more effective and efficient administrative systems, particularly within government institutions. One crucial element of administration in the public sector is the management of official documents such as Assignment Letters (Surat Perintah Tugas, SPT) and Official Travel Orders (Surat Perintah Perjalanan Dinas, SPPD). At the Health Office of Majalengka Regency, the preparation and management of these documents have traditionally been carried out manually, leading to inefficiencies, a higher risk of human error, and difficulties in archiving. This study aims to design and develop a web-based application for managing SPT and SPPD documents using the CodeIgniter framework. The system includes features such as automatic document generation with standardized templates, electronic approval workflows, centralized digital archiving, and document tracking functionalities. The Rational Unified Process (RUP) methodology was applied in the development stages, covering inception, elaboration, construction, and transition. The results indicate that the application successfully automates the creation and management of SPT and SPPD documents, significantly improving efficiency, accuracy, and accessibility. Digital archiving ensures better security and faster retrieval of documents, while the user-friendly interface allows employees to operate the system with minimal training. The implementation of this system supports the digital transformation initiatives of local government agencies and contributes to improving the quality of public services in the health sector.

Abstract

Tilapia cultivation in Kampung Nila Kawali relies heavily on air quality as a key success factor. Currently, air quality monitoring is still done manually, resulting in inaccurate results, especially with a large number of ponds and extensive cultivation areas. This study aims to design an integrated pond quality monitoring and maintenance system tailored to user needs. The system was developed using the Extreme Programming (XP) method, with stages of planning, design, coding, and testing. This method was chosen because it is flexible to changing needs, accelerates development, and improves communication between developers and users. The design results indicate that the system successfully meets user needs in terms of interface and features. The system can display information on air quality parameters, pond locations, maintenance schedules, and air quality history in a concise and easy-to-understand manner. A warning notification feature is also designed to provide immediate information when air quality parameters are outside normal limits or require maintenance action.

Abstract

Bushing is a mechanical component that functions to reduce friction, absorb vibration, and extend the lifespan of machine parts. This study was conducted through practical work at PT. Amanah Jaya Persada to analyze the production process of bushing using a conventional lathe machine. The research method involved observation, literature study, direct practice, and data collection. The production stages included design using Computer Aided Design (CAD), machining with a conventional lathe, finishing, and quality control. Calculations of machining parameters such as cutting speed, feed rate, depth of cut, and machining time were also performed. The results showed that the conventional lathe machine can produce bushings that meet dimensional standards and tolerances of ±0.05 mm. The success of the process depends on proper tool selection, accurate calculation, and operator skills. Although CNC machines provide higher precision, conventional lathes remain effective and economical for small to medium-scale production.

Abstract

The process of making sprockets using a lathe begins with rolling a suitable raw material, such as steel or another metal alloy. The raw material is then installed on the lathe machine table and clamped tightly. After that, the lathe knife is placed near the workpiece and regularly moved in the specified direction, cutting off excess material until it reaches the desired shape and size. Operating a lathe requires a skilled operator to produce sprockets with tight tolerances. The purpose of writing a practical work report at PT. Amanah Jaya Persada is to know the process of making sprockets and know the lathe and CNC processes in making sprockets. The conclusion from this research is that there are 4 processes for making sprockets at PT. Amanah Jaya Persada, namely making drawings using Solidwork, forming shaft holes using a lathe, forming chamfers using a lathe, forming a chain release (Undercut) using a lathe, and forming sprocket teeth using a CNC milling machine.
