This research employs a descriptive qualitative approach through field observations, in-depth interviews, and documentation involving local farmers, community leaders, and relevant stakeholders. The findings reveal that economic aspects, such as production cost efficiency and income improvement, are highly dependent on stable environmental conditions and strong social support. Conversely, environmental degradation and weak social participation hinder business development. Therefore, participatory-based policies integrating sustainable environmental management with the strengthening of local socioeconomic capacities are urgently needed. This study offers a significant contribution as a foundation for formulating empowerment strategies for environmentally and socially-based small-scale aquaculture enterprises at the village level.

Green Open Space (GOS) plays a strategic role in modern urban planning, serving not only as an ecological element but also as a social, educational, and recreational space that supports the sustainability of urban life. Its presence is a vital necessity in addressing the challenges of urbanization and environmental degradation. This study examines and redesigns Taman Mandiri in Jayapura City as a sustainable urban park capable of accommodating various ecological and social functions. Field observations reveal that the existing condition of the park does not yet meet adequate public facility standards, such as the availability of interaction space, playgrounds, toilets, and parking areas. Through a sustainable landscape design approach, the park is directed to become an inclusive, efficient, and environmentally friendly green open space. The proposed design integrates the use of local vegetation, natural water management systems, and the enhancement of the park’s social functions. It is expected that this design can serve as a model for urban park development in tropical regions facing urbanization pressures and contribute to improving the quality of life in a sustainable manner.

Climate change has emerged as one of the most pressing and multifaceted threats to national security across the globe, including in Indonesia. The consequences of climate change extend far beyond environmental degradation, posing significant risks to critical sectors such as food security, water resources, social cohesion, and the overall stability of national defense systems. Rising temperatures, shifting precipitation patterns, and the increasing frequency of extreme weather events-such as floods, droughts, and storms-have direct and indirect impacts that undermine the resilience of communities and the functionality of state institutions. In Indonesia, a country characterized by its vast archipelago and diverse ecosystems, the climate crisis presents unique challenges. The vulnerability of coastal regions to sea-level rise threatens the livelihoods of millions, while disruptions in agricultural productivity jeopardize food availability and economic stability. Moreover, these environmental stresses exacerbate social inequalities and can trigger internal displacement, heightening the risk of social unrest and conflict. Such dynamics underscore the critical intersection between environmental changes and national security concerns.

Clean water is a basic necessity that not only affects health but also social welfare and environmental sustainability. The aim of this research is to evaluate the level of public awareness in the Tegal Sari Mandala II sub-district regarding the use of clean water for household purposes and to identify the factors that influence public awareness in the utilization of clean water in the Tegal Sari Mandala II village. This research uses a qualitative approach with a descriptive evaluative method. Data in this study were collected through interview techniques, observation, and document studies, and analyzed using thematic analysis techniques.

Efforts made by using service quality strategies and human resource improvement strategies.

Rapid development and population growth in urban areas have caused various problems, one of which is the decreasing availability of clean water. This has an impact on the agricultural and fisheries sectors which are highly dependent on good water quality. As an alternative to overcome this problem, the aquaponic system offers a solution by combining fish and plant cultivation in one efficient water recirculation system. However, the quality and productivity of the aquaponic system are highly dependent on good management, which requires proper monitoring and control of environmental conditions such as temperature, pH, humidity, and water quality. This study aims to design and build a Node-RED-based aquaponic monitoring and control system. This system uses various sensors to monitor environmental conditions and provide automatic control of parameters that affect plant and fish growth. By using Node-RED as a platform for sensor and control integration, this system is expected to provide an efficient and affordable solution to increase the productivity of the aquaponic system. The results of the study show that the designed tool can carry out effective monitoring and control of parameters that affect the aquaponic system, and can be accessed in real-time to facilitate system management and supervision.

This study aims to assess how the development and tourism potential of Parepare City are perceived by the local community. Using a mixed-method approach (qualitative and quantitative), this research analyzes five main components (A5): Attraction, Amenities, Ancillary Services, Activities, and Accessibility, utilizing the Weighted Analysis technique (Likert Scale) to provide a structured evaluation. The findings indicate that public perceptions of tourism development vary. Artificial attractions received high ratings and are considered a key strength. Regarding amenities, the availability of places of worship was rated as the most adequate. However, in ancillary services, facilities such as clean water, electricity, and culinary services still require improvement. In terms of activities, events like festivals and recreational activities were deemed to be suboptimal in terms of implementation, management, and the involvement of local SMEs. Meanwhile, in the accessibility component, institutions such as Pokdarwis have not been effectively implemented. Therefore, a development strategy is needed that actively involves the community through training and empowerment, as well as continuous support from the government. Infrastructure improvement and regular evaluations are essential steps to enhance tourist interest in visiting Parepare City.

Natural gas is an essential industrial fluid, and its distribution requires a pipeline system that is safe and leak-free. Leakage in natural gas pipelines remains a major concern, as it reduces public confidence in using gas for household purposes. Therefore, testing is conducted before the pipeline network is operated. One commonly used method to detect leaks is the Pneumatic Test, which evaluates the strength and integrity of pipes and their joints according to standards for polyethylene natural gas pipelines. This test uses compressed air supplied by a compressor, with pressure and temperature measured at the inlet pipe using a pressure gauge. The study found no pressure changes or leakage throughout the test. The calculated holding time required for the pneumatic procedure was 1 hour, 26 minutes, and 8 seconds. Non-Destructive Testing (NDT) results showed that: (a) at 50% of test pressure (approximately 10 bar), the pipe held for 15 minutes with no pressure drop; (b) at 75% (around 15 bar), pressure remained stable for 15 minutes; and (c) at 100% (20 bar), pressure was maintained for 75 minutes without loss. Welding was performed using Nikko Steel electrodes (2 mm × 300 mm, 50–80 A), supported by proper safety gear and tools, and a Riland welding machine with a 400-A capacity.

Settlement is a basic human need that is closely related to the feasibility of life and well-being. The purpose of this study is to gain a better understanding of settlement patterns that occur in rural and urban areas, and to investigate the factors that influence these patterns. This study collects, analyzes, and synthesizes related literature. The results show that settlement patterns in urban areas are denser and develop vertically, while settlement patterns in rural areas tend to be spread out and horizontal. Various factors, such as natural conditions (such as climate, topography, water and land availability), socio-economic factors (such as employment, education, and income), and government policies and local cultural developments, influence these differences. These results emphasize that understanding settlement patterns as a whole is essential to building areas that are equitable, sustainable, and responsive to community needs.

The Drinking Water Supply System (SPAM) is essential infrastructure for ensuring access to clean water. SPAM Tembudan, located in Batu Putih District, Berau Regency, plays a key role in supplying raw water for both domestic and non-domestic uses. This study analyzes the sustainability of SPAM Tembudan by evaluating raw water quality, availability, and system efficiency. Primary data were collected through field surveys, water sampling, and interviews with operators and residents. Water quality was assessed based on physical, chemical, and biological parameters, following Ministry of Health Regulation No. 492/Menkes/Per/IV/2010. Availability was evaluated through flow rate measurements and community water demand, while system efficiency was assessed by examining treatment efficiency and water loss (Non-Revenue Water/NRW). Findings reveal that most water quality parameters meet national standards, though some show signs of potential contamination. In terms of availability, raw water is currently sufficient to meet demand, but seasonal changes particularly during the dry season threaten long-term sustainability. The analysis also identifies inefficiencies in the distribution network, with notable water losses that need addressing. To ensure the long-term sustainability of SPAM Tembudan, the study recommends enhancing the treatment process, improving raw water resource management, and reducing distribution losses. Encouraging community involvement and strengthening the capacity of local operators are also critical for maintaining the system’s performance. These strategies aim to secure reliable, high-quality drinking water for the community while supporting sustainable resource use.

Global climate change has caused changes in rainfall patterns in various regions, including North Jayapura District, Papua Province. This study aims to analyze changes in rainfall characteristics in the region over the past two decades (2004–2023) using GSMaP satellite data. The analysis was carried out on the average monthly rainfall, annual rainfall, decadal trends, hourly rainfall intensity frequency, and daily rainfall duration. The results showed a decrease in annual rainfall accumulation in the 2014–2023 decades compared to the previous decade (2004–2013), with a difference of around 5,000 mm. The seasonal rainfall pattern still shows concentration in January to March, but with a significant decrease in these wet months. In addition, there was an increase in the frequency of short-duration rain (<1 hour) and moderate to very heavy rain, although the frequency was still relatively small. The high variability of annual rainfall also indicates an increasingly large climate. These findings indicate that North Jayapura District faces the risk of increasing extreme rainfall events and decreasing water availability in the long term. Therefore, adaptation efforts are needed through improving early warning systems, conservation of air catchment areas, and integration of satellite data and field observations in air resource management planning.

A healthy latrine is one of the essential sanitation facilities aimed at maintaining environmental health and improving public health in general. This research was conducted because the use of healthy latrines in Webetun Village remains low, where defecating in the forest has become a common practice among the community. This habit triggers the emergence of diseases such as diarrhea, malnutrition, undernutrition, dengue fever, and respiratory infections. This study aims to examine the behavior of latrine use in households in Webetun Village, Rinhat Subdistrict, Malaka Regency. This research uses a quantitative approach with a cross-sectional design. The study involved 66 housewives who owned healthy latrines, selected through simple random sampling. Data analysis was conducted using the chi-square test. The results showed that variables such as latrine ownership (p=0.000) and water availability (p=0.000) were significantly associated with latrine use, while knowledge (p=0.681), attitude (p=0.588), actions (p=0.007), community leader support (p=0.081), and health worker support (p=0.069) were not significantly associated with latrine use. The findings revealed that water availability significantly influences latrine use. The availability of water facilitates family members in utilizing latrine facilities for activities such as flushing and maintaining cleanliness. Water availability also contributes to user comfort in maintaining latrine hygiene. Conversely, water scarcity hinders optimal latrine use by family members, potentially reducing utilization levels. The study findings also identified a correlation between latrine ownership and its use. Families are considered critical factors in shaping individual health behavior. The relationship between proper latrine ownership and usage behavior can be seen through the role of education in increasing awareness levels for adopting a healthy and clean lifestyle. 

Red snapper (Lutjanus sp) in Brondong waters, Lamongan Regency, is one of the main sources of livelihood for local fishermen. To increase the catch, optimizing the use of fishing gear, including setting time, is important. This study aims to determine the effect of differences in setting time on hand line fishing gear on red snapper catches. The study was conducted using the experimental fishing method, by dividing the setting time of hand line fishing gear into 2 treatments, namely morning 08.00-11.00 and afternoon 15.00-18.00. Based on the T test on paired samples, the average catch at 08.00-11.00 WIB was 2,131 with a total of 34.1 kg, while at 15.00-18.00 WIB, the average catch reached 6.4 with a total of 102.4 kg. The T-test results show that the t-count is greater than the t-table, so the null hypothesis is rejected and it can be concluded that there is a significant difference between the red snapper catches in the two time periods. Red snapper tends to be more active in foraging in the afternoon to evening, in line with its nocturnal nature. Several studies have stated that predatory fish such as red snapper hunt more when the light begins to dim. However, other factors such as food availability and physical conditions of the waters can also affect fish feeding activity. These findings provide additional insight into the feeding behavior of red snapper and the factors that influence its presence in the waters.

This research aims to analyze the effect of different setting depths of handline fishing gear on catches of yellowfin tuna (Thunnus albacares) in Mentawai waters which are landed at the Bungus Ocean Fishing Port. The research was carried out using field experimental methods at three setting depths, namely 25 meters, 50 meters and 75 meters. The research results show that a depth of 25 meters produces the most optimal catch compared to other depths. This depth has the advantages of abundant availability of target fish, optimal visibility, as well as temperatures and oxygen levels that support fish activity. Data were analyzed using analysis of variance (ANOVA) and Least Significant Difference test (LSD). The analysis results show that differences in depth have a very real influence (**). These findings provide practical guidance in optimizing fishing gear depth to increase catch yields sustainably.

First Come First Served (FCFS) in the meeting scheduling system at the North Sumatra Provincial Transportation Office can be applied to organize the queue of requests for the use of meeting rooms or meeting schedules based on the order of arrival of requests. The results of this study indicate that the implementation of a web-based meeting scheduling system can increase efficiency and reduce schedule conflicts at the North Sumatra Provincial Transportation Office. This system can facilitate the process of managing meetings and increase work productivity.

Indonesia, as an archipelagic country with over 17,000 islands, faces significant challenges in providing electricity access, particularly to small and remote islands. One promising solution is Solar Power Plants (PLTS), both land-based and floating solar plants that utilize water surfaces, suitable for areas with limited land availability. This study evaluates the economic feasibility of floating solar plants and land-based solar plants using the Levelized Cost of Electricity (LCoE) approach. LCoE encompasses all costs of construction, operation, maintenance, and energy production over the plant's lifespan, serving as a key benchmark in selecting power generation technologies. The findings show that the LCoE for floating solar plants is Rp11,197.00/kWh, lower than land-based solar plants at Rp11,769.00/kWh, although both exceed the electricity purchase price in Kodingareng, South Sulawesi, at Rp2,460.00/kWh. This difference is influenced by higher construction costs for floating solar plants but offset by greater energy output and lower operation and maintenance costs. This research provides a basis for developing solar power systems in archipelagic regions, emphasizing efficiency and sustainable energy solutions.
