Abstract

Cybery Beach is a beach that has enormous potential to be developed, besides being very close to the center of Jayapura, this beach is the only beach located right next to the Youtefa Bridge and the Youtefa Bay Estuary so it has enormous potential to be developed because it is visited by many visitors in Jayapura city, Cybery Beach is also located on the ringroad and eastward with Holtekamp Beach, environmental safety is a shared responsibility of both the government, the community, visitors in keeping the environment clean and well maintained.The purpose of this service activity is to socialize the Love Environment Movement carried out by the Cenderawasih University Service Team. Public awareness, especially visitors to Cybery beach, of the importance of maintaining environmental cleanliness is still very lacking because there are still people who litter, especially plastic waste used as food wrappers which are left scattered around the beach. The importance of understanding the concept of environmental safety for the community from an early age so that environmental cleanliness can be enjoyed by all communities and public benefits can be achieved through environmental hygiene social action. The basic nature of environmental management and conservation is the main capital for the development of natural resources and human resources so that an active role of the community is needed to strive for environmental conservation.The results achieved in the service are that with this activity, it can foster enthusiasm in saving the environment, even through this activity the Love the Environment Movement can be campaigned, especially in saving Cybery Beach.

Abstract

The sago plant (Metroxylon sago) is native to Southeast Asia and thrives in swampy areas and riverbanks in Indonesia, with centers of distribution in Papua, Maluku, Sulawesi and Riau. In Papua, sago plays an important role in the social, economic and ecological aspects of the local community, as well as being a staple food consumed for generations. However, rapid development in Jayapura Regency, especially in Nendali Village, threatens the sustainability of the sago forest. This research uses a descriptive method to evaluate the existing condition of sago forest shrinkage through observation, interviews, and documentation. The results showed that development activities have caused the sago forest area to shrink by 114,629.76 m² between 2015 and 2020. Sago forests were converted into built-up land and open land, which amounted to 5,864.59 m² and 5,284.53 m² respectively. The SWOT analysis revealed that despite internal weaknesses, opportunities for sago forest protection exist through existing regulations. Thus, it is expected that the Jayapura District Regulation can be a reference in sustainable development and protection of sago forests for the welfare of local communities.

Abstract

U-Turn Facilities serve to accommodate vehicles changing the direction of travel. Trikora road Manokwari has a U-Turn that causes traffic flow conflicts. The problem occurs because the vehicle cannot make a U-Turn movement properly, so it takes more time when making a U-Turn movement. The purpose of study was to analyze traffic flow conflicts, road geometrics, and level of service. Data collection method by direct observation for 7 days at 07.00 AM to 08.00 AM, 08.00 AM to 09.00 AM, 11.00 AM to 12.00 PM, 12.00 PM to 13.00 PM, 16.00 PM to 17.00 PM and 17.00 PM to 18.00 PM at the research location. Data analysis using MKJI 1997. The results of data analysis obtained a maximum traffic volume of 1308 pcu/hour. Side obstacle class Medium with a weighted frequency 390 with industrial area conditions, several shops on the side of the road. Road capacity of 5562 pcu/hour. Maximum vehicle of 24,70 meters. Disturbed traffic flow speed of 27,32 kilometers/hour. Road shoulder width of 1,5 meters. Level of service value of 0,44 (A). Keywords: U-Turn, Road Geometrics, Traffic Flow, Capacity

Abstract

Groundwater is dynamic and influenced by natural factors, such as geology and geomorphology, which affect aquifer characteristics, groundwater movement, and surface morphology. This study aims to identify subsurface aquifer positions and the distribution of groundwater depth in Oksibil District, Pegunungan Bintang Regency. The research utilizes the resistivity geoelectric method with a Wenner configuration to determine lithology and aquifer characteristics. Measurements were conducted using the AIDU Golden Rod instrument, which analyzes natural electric fields. Results indicate the presence of pressurized aquifers at depths ranging from 125 to 300 meters with varying thicknesses of 20 to 85 meters. In contrast, free aquifers are primarily located at shallow depths (0–40 meters) in specific areas, such as Kabiding. The findings provide valuable insights into groundwater resource management and regional aquifer potential in Pegunungan Bintang Regency
