Abstract

This community service activity aims to implement a bullying and violence prevention application in a partner school to create a Child-Friendly School (CFS). The main issue identified is the lack of shared perception and commitment among school personnel, students, and parents regarding the concept of bullying. The methods used include socialization, training, mentoring, as well as monitoring and evaluation. The results of the activity show an increase in understanding and commitment of all parties in preventing bullying, as well as the formation of a more effective prevention mechanism. The importance of these results is to build a safe and comfortable school environment for all students, and ultimately to achieve the vision of child-friendly education in Semarang City

Abstract

Geographic Information System (GIS) plays a key role in managing livestock population data and planning the development of the livestock sector. In Central Java Province, the implementation of GIS-Livestock Population (GIS-LivPop) has successfully mapped the number of livestock populations based on geographical location, district/city, and livestock type in 2022. Through GIS technology, GIS-LivPop facilitates the mapping of the distribution of cattle, goats, sheep, chickens, and other livestock in the Central Java region. This data is an important source of information for planning, monitoring livestock diseases, supplying animal feed, and developing the livestock economy.

Abstract

Water is one of the building blocks of the human body. With a percentage of around 70% in the human body, water is important for survival. Humans use water in everyday life for various purposes such as washing, cooking, drinking water, bathing and others. The water usually used is ground water. However, not all groundwater houses have good quality for drinking or cooking water. Knowing this problem, the central government, through regional governments, established regional drinking water companies (PDAM) in each region to provide drinking water that is clean, healthy and meets health requirements for the community, which is also a form of service provided by the government to the community. This PDAM is considered not to have reached all regions so a system is needed that is able to provide data quickly. The rapid development of information technology in the current era of globalization provides many benefits in progress, one of which is geographic information. The Quantum GIS application can be used to create, edit, visualize, analyze, and process geospatial information. Quantum GIS can visualize spatial data and non-spatial data involved in this research. The aims and objectives of this research are to design and build a program that makes it easier for various parties such as the community and government to facilitate data management by utilizing geographic information systems in mapping regional drinking water company (PDAM) customers.

Abstract

Employment is one of the main concerns of the Central Java Provincial Government. The aim of this research is to determine employment conditions in Central Java using several indicators. The research results show that although Central Java's TPAK has increased from year to year, the difference between men's and women's TPAK is still large. TPT for men is higher than TPT for women, and urban TPT is higher than rural TPT. The TPT for Vocational High School (SMK) graduates is always the highest, compared to the TPT for graduates of other levels of education. Based on main employment status, the working population can be categorized into formal and informal activities. Residents who work in formal activities include those who work with the help of permanent workers and workers/employees/employees, while the rest are categorized as informal activities (self-employed, businesses assisted by temporary workers/unpaid workers, casual workers, and family/unpaid workers ).

Abstract

Stunting is a chronic nutritional problem  in most of developing countries for quite a long time, including Indonesia. In 2018, Indonesia had 30.8% of stunting toddlers, 29.6% in 2017 and 27.54% in 2016. The trend over the last 3 years the prevalence of stunting has increased. The purpose of this research is to map the spread of stunting toddlers and exclusive breast milk coverage in Indonesia. This research is a cross sectional study using secondary data sourced from reporting compiled by the Ministry of Health of the Republic of Indonesia in 2018. WebGIS is used to compile mappings of both variables in each province through the official website of BPS. The results of this study show the information presented in WebGis seen most provinces have a prevalence of stunting in black zones (very high) and exclusive breast milk coverage in red zones (very less met than national targets).

Abstract

In the digital era, sentiment analysis plays a strategic role in understanding customer perceptions of products and services. This research aims to analyze customer review sentiment on the Lazada platform through the application of text processing techniques and machine learning algorithms. Data is taken from product reviews on the platform, which then undergoes a preprocessing stage, including tokenization, stopword removal, and stemming using the Sastrawi algorithm. Next, sentiment classification was performed using a Support Vector Machine optimized through the Particle Swarm Optimization (PSO) method. The research results showed that the combination of the Sastrawi stemmer method and SVM-PSO was able to achieve significant accuracy, namely 90.57%, an increase of 6.24% compared to previous research. These findings provide deep insights into customer perceptions and offer valuable guidance for decision-makers at Lazada in improving service quality and customer satisfaction. This study also underscores the importance of applying Natural Language Processing techniques and machine learning algorithms in sentiment analysis on e-commerce platforms, which have proven to produce more accurate outputs.

Abstract

Population administration and correspondence services at the village and sub-district levels often present obstacles for the community, especially since they must come directly to the office to handle various needs. In an effort to overcome this problem, the community service team sought to develop sipsidomukti on SIPsiMas (Community Administration Service Information System), which is a digital-based system that allows to community of Sidomukti sub-district, Salatiga City, to process documents online. The program aims to improve the efficiency of administrative services, reduce queues at village and sub-district offices, and provide easy access for the community without time and place restrictions. The system development is carried out using web-based technology and mobile applications that allow residents to submit, monitor, and print documents independently. The program implementation methods include: needs analysis, design and development, outreach and training, and evaluation and improvement. With the existence of sipsidomukti in SIPsiMas, administrative services in Sidomukti sub-district have become faster, more transparent, and more efficient, increasing public satisfaction with public services.

Abstract

Purpose: The purpose of this study is to be able to avoid limitations of inexpensive ID card data extraction services and preserve privacy, which can simultaneously achieve reliable operation even under an environment with minimum infrastructure, in particular if no dependency on GPU-based servers are required. Method: The proposed approach is a microservice pipeline with three stages: (1) local lightweight pre-processing on devices, (2) Tesseract CPU-based OCR. js, (3) fast text tokenization through a small premature external LLM. The system is developed as TypeScript backend utilizing the Hono framework with all image processing taking place locally in order to keeping user data private. Result: The result of the experimental evaluations with real ID card samples is that the system can run stably in low-performance VPS (1 vCPU, 1 GB RAM) with operation cost approximately IDR 2.5047 per extraction process and its accuracy level is acceptable for use in a production environment. Moreover, the results indicate that system latency is dominated by LLM inference at the cloud. Novelty: The main contribution and novelty of this study is that we demonstrate, for the first time, a cost-effective (privacy-preserving) OCR-LLM hybrid pipeline without demanding expensive GPU models at large scale which makes our system suitable under limited storage and resource constraints on-premises or edge environments in small organizations including micro-SaaS services.
