Abstract

This community service project aims to design and implement a solar-powered street lighting system integrated with the Blynk application using Internet of Things (IoT) technology. The partner community faces challenges due to limited access to street lighting infrastructure, which affects social activities and residents' safety, especially at night. The designed system utilizes solar panels as the primary energy source, batteries for power storage, a NodeMCU ESP8266 microcontroller as the control center, and the Blynk application that allows remote monitoring and control of the lights via smartphones. An LDR sensor is used to detect ambient light intensity so that the lights automatically turn on at night and off during the day. Additionally, users can access the system status and manually control the lights through the Blynk app. The implementation results show that the system operates effectively, is energy-efficient, and is easy for residents to use. Active community participation in the training and installation process also enhanced their understanding of renewable energy utilization and digital technology. This program makes a tangible contribution to improving the community’s quality of life by providing sustainable and environmentally friendly lighting. Moreover, this innovation has the potential to be replicated in other areas with similar characteristics and challenges.

Abstract

Akcaya Park is one of the open green spaces that plays an important role in providing recreational facilities, supporting social interaction, and improving environmental quality in Pontianak City. However, the park’s existing condition shows a decline in the quality of its facilities, aesthetics, and spatial utilization, making revitalization efforts necessary. This study aims to design a revitalization concept for Akcaya Park that can optimize its ecological, social, and aesthetic functions in accordance with community needs and technical standards for green open space planning.The methodology includes field surveys, collection of primary and secondary data, analysis of existing conditions, and the preparation of a design concept based on landscape planning principles and relevant technical guidelines. The design takes into account spatial arrangement, circulation, supporting facilities, lighting, vegetation, and environmental sustainability. Based on the design results, the revitalization of Akcaya Park focuses on improving accessibility, comfort, and optimizing the park’s functions, which include upgrading the children’s playground, relaxation garden, parking areas, public toilets, basketball court, waste management facilities, and lighting. This design is expected to meet community needs and contribute to the creation of a green, comfortable, and sustainable city.

Abstract

Benua Melayu Darat, located in South Pontianak Regency, relies heavily on artificial drainage systems to control surface runoff and flooding. However, the area still frequently experiences flooding during high rainfall intensity. Therefore, this study was conducted to evaluate the performance of the drainage system in Benua Melayu Darat District from a hydraulic and non-technical perspective and to identify the dominant factors contributing to channel dysfunction. The evaluation began with hydrological and domestic wastewater analyses to determine the total water volume to be accommodated by the existing channels. A hydraulic analysis was then conducted to determine the channel’s design discharge. Direct field measurements were performed to assess channel dimensions and flow velocity, and non-technical analyses were conducted of sedimentation, waste, and land cover. The results showed that 45% of channels in Benua Melayu Darat District had inadequate capacity to accommodate rainfall and domestic wastewater. Non-technical factors, such as uncontrolled sedimentation rates and garbage blockages, also significantly disrupted channel function. This study shows the need to normalise dimensions and channels, implement low-impact development systems, such as retention ponds, strengthen maintenance programs to ensure adequate drainage, and provide public education on how to maintain or protect the environment to prevent flooding.

Abstract

Estuaries function as sediment deposition zones that provide essential substrates for mangrove development. Consequently, estuaries and mangroves constitute integral components of coastal ecosystems. The mangrove ecosystem in the Belawan Estuary, North Sumatra Province, is increasingly threatened by rapid urban expansion in Medan City. This study aimed to assess mangrove biodiversity, structural characteristics, and ecological status in the Belawan Estuary. Field surveys were conducted in November 2023 across 28 sampling stations representing seaward, middle, and landward sections of the estuary. Vegetation data were analyzed using density, diversity, evenness, dominance, and Importance Value Index (IVI). A total of 26 mangrove species were recorded, comprising 21 true mangrove species and 5 associated species. The most widely distributed species were Avicennia marina, Avicennia lanata, and Nypa fruticans. Mangrove density ranged from 533 to 2,733 ind ha⁻¹, with an average of 1,420 ind ha⁻¹. Shannon–Wiener diversity values ranged from 0.04 to 1.95, indicating relatively low diversity in several landward stations dominated by N. fruticans. Although the overall condition of mangroves in the Belawan Estuary is classified as good, the ecosystem remains highly vulnerable to land-use conversion under the revised spatial planning framework. Strengthening conservation-oriented spatial policy is therefore essential to ensure long-term ecosystem sustainability.
