Abstract

Internet addiction is a type of behavioral addiction marked by excessive and uncontrollable use of the internet, which adversely affects an individual's psychological and social well-being. This research investigates the psychological aspects of internet addiction among young adults in digital work environments, utilizing Pavlov's classical conditioning theory to explain the addictive behaviors. A qualitative case study approach was employed, involving a 26-year-old female participant who was evaluated through interviews, observations, and five psychological assessments: the Internet Addiction Test (IAT), DSM-5 criteria, the ABC model, the SORC model, and a self-recording diary. Findings revealed that the participant spent 15-20 hours online daily, primarily to escape stress and boredom, achieving an IAT score of 78, indicating severe addiction, and fulfilling over five DSM-5 criteria for behavioral addiction disorder. The analysis indicated that digital stimuli, such as notifications and visual cues, elicited compulsive responses, reinforcing automatic behaviors. The results align with Pavlov's theory, highlighting the importance of behavior-focused interventions, digital literacy, and social support in combating internet addiction among young adults.

Abstract

Traditional games are part of cultural heritage that contain historical and educational values. One example is the ontel bicycle, a classic bicycle still widely known among Javanese people as the "kebo bicycle." However, along with the development of technology and modern lifestyles, the younger generation's interest in traditional games has decreased. This condition encourages the need for an alternative approach to reintroduce the ontel bicycle to the current generation. This study aims to design and develop an Android-based ontel bicycle racing game that is educational and supports cultural preservation. The research method used in the development process uses the Unity platform, while the testing phase was conducted using black box and white box methods. Based on the test results, the application runs according to the designed logic and no logical errors were found, with a cyclomatic complexity of V(G) = 3. This game application is equipped with a main menu, game levels with various difficulty levels, and information about the developer.

Abstract

Traditional Bugis cakes are an important and distinctive part of Indonesian culinary culture, yet their existence is starting to erode due to globalization and a lack of proper digital documentation. The visual similarities between the cakes make manual identification difficult, especially for the younger generation who are more exposed to modern, global food trends. This study aims to develop an Android application for the automatic classification of traditional Bugis cakes using a Convolutional Neural Network (CNN). The experimental method was conducted by collecting a comprehensive dataset of cake images, training a CNN model, and evaluating its performance using a black box testing approach. This method was chosen because it yielded a validation accuracy of 97.00% and a final accuracy of 92.40%. The application can recognize cakes in real-time through a mobile phone camera, with optimal results achieved at a distance of 15–30 cm and under adequate lighting conditions. However, its performance decreases when the distance increases, objects are cut off, or lighting is poor.

Drought is one of the natural disasters that significantly affects people's lives, particularly in terms of clean water availability and the agricultural sector. Pesisir Selatan Regency is an area prone to drought due to prolonged dry seasons and decreased rainfall. This study aims to identify the level of drought vulnerability and map the distribution of drought-prone areas in Pesisir Selatan Regency using a scoring method based on Geographic Information Systems (GIS). The parameters used in the analysis include land use, slope gradient, rainfall, soil type, and river networks. The data were obtained from administrative maps, spatial data, and hydrological and climatological information. The results show that most areas in Pesisir Selatan Regency fall into the moderate vulnerability category, while areas with high vulnerability are commonly found in residential and rice field zones. In contrast, areas with low vulnerability are located near water bodies and are highly influenced by high rainfall levels.

Abstract

Stunting remains one of the major chronic nutritional issues in Indonesia. According to the 2021 Indonesia Nutrition Status Study (SSGI), the national stunting prevalence reached 24.4%, while in West Sumatra Province it was recorded at 25.2% in 2022. Although Padang City showed a significant decrease to 3.7% based on 2023 e-PPGBM data, continuous intervention is still necessary. Various socioeconomic factors such as parental education, family income, number of children, and household size have been shown to influence the incidence of stunting. However, spatial-based approaches to analyze the distribution of stunting cases at the local level remain limited. This study aims to map and analyze the spatial pattern of stunting in Padang City using Geographic Information Systems (GIS). This method enables a geographic visualization of case distribution, supporting more targeted policy decisions. The findings of this study are expected to provide accurate spatial data to strengthen integrated and sustainable efforts in stunting prevention in urban areas.

Abstract

Over time, the yield of oil palm had continued to increase each year, which was followed by a rise in the amount of waste produced. One of the main wastes from palm oil processing was liquid waste, commonly known as Palm Oil Mill Effluent (POME). This study aimed to obtain a ZnO/Cu catalyst and to determine the optimal catalyst weight and irradiation time to reduce COD, TSS, and pH values. The ZnO/Cu catalyst was synthesized using the co-precipitation method and was applied through a photocatalytic process, which utilized catalysts and ultraviolet (UV) light. The catalyst was applied to POME with ZnO weight variations of 100 mg, 150 mg, and 200 mg, and UV irradiation times of 30, 60, 90, 120, and 150 minutes. The best result was obtained at a catalyst weight of 200 mg and an irradiation time of 150 minutes, resulting in COD of 216 mg/L, TSS of 20.00 mg/L, and pH of 7.39, which met the wastewater quality standards.
