Abstract

The location of the study in this study is the Sentani watershed which is located in Jayapura City and Jayapura Regency. In the Sentani watershed, there is Lake Sentani which has potential utilization in the form of a Drinking Water Supply System (SPAM), Irrigation Needs of Agricultural Areas, Power Plants, Utilization of Business Development in the Fisheries Sector and Lake Ecotourism Destination Areas. With the growing utilization in the Sentani watershed, an analysis of water allocation is needed to determine the ability of the Sentani watershed to meet its needs. The Head of PDAM Jayapura explained that Lake Sentani has the potential to be an alternative to overcome the reduced water discharge and water supply for the community in Jayapura Regency. So it is hoped that this research can contribute to providing a foothold for water utilization recommendations for the community in Jayapura Regency. The results of this study show that Lake Sentani can meet water needs both with existing intakes and with the fulfillment of new needs to be developed. The total raw water taken based on the existing intake is 0.926 m^3/s and the plan to increase the raw water intake in Jayapura district is 0.125 m^3/s.

Abstract

Under Presidential Decree No. 60 of 2021, on National Priority Lakes Rescue, Lake Sentani is one of 15 priority lakes to be rescued. In the annex to the President's regulation, it is mentioned to date about 90 tons or ± 5 m/year of sediment entering Lake Sentani with a total count of 62,0679.78 tonnes/year entering lake Sentani, with a storage capacity of 1,782 billion/m3. The water supply of Lake Sentani is obtained from the supply of 14 large and small rivers. With a slope inclination between 0% - 40% of the amount of sediment transported during the rainy season causes the decline in water quality and the high erosion that occurs. This study aims to find out the impact of land-use change and the effect of sediment control buildings on the number of sediments that enter Lake Sentani. From the results of the analysis the impact of land use change before the construction of the sediment control building based on the analysis carried out by the Papua River Regional Hall the known potential sedimentation rate is of 0.6 mm/th whereas the potential sedmentation rate analysed after the existence of the building of the Sediment Controller is of 0.012 mm /year. This indicates a change in the rate of potential Sedimentation entering the lake of sentani affected by the building sediment operator. When it rains with repeated flooding Q20, Q25, Q50 and Q100 years with conditions of 1 (one) sediment control building so that it can be judged to be a very heavy erosion class with land loss of more than 280 tons/ha/years with a potential sedimentation rate thickness between 2.55 mm/years to 2.85mm/years.

Abstract

Development of irrigation district (DI) in Nabire district began from 1972/1973 until 2014 the government carried out is 6400 ha. The purpose of this study is to eval_uate the performance of the wells and networks of the irrigation areas of the calibumi. The results of this study are known that the performance of Nabire's wells and irrigation networks that have been awakened is still in low performance and require attention with the overall value of 64.74% consisting of the performance value of the physical Prasarana 24.34%, plant productivity 9.86%, the supporting networks 3.33%, the Organization of Personnel 9.18%, Documentation 2.74% and P3A/GP3A / IP3A 5.37% This indicates that the existing operating and maintenance system is still very poorly in accordance with the Regulation of the Minister of Public Works and People's Housing No. 12/PRT/M/2015 on the Exploitation and Maintenance of Irrigation Networks as assessed using the e-PAKSI application.

Abstract

This research involves several PLN substation projects in the Maluku and Papua regions. The subject of this study consisted of 25 respondents, namely 1 Project Manager, HSE Engineer and project supervisor. The questionnaire that has been given is then analyzed using the severity index method. The results of K3 risk identification on 44 risk variable indicators with high variables are found in the categories of product purchase and control, work safety in SMK3 and monitoring standards. The highest level of K3 risk to cost performance in substation construction projects in Maluku and Papua is the specification of the purchase of goods and services, the verification system of purchased goods and services, emergency planning and recovery, and labour health monitoring. The allocation of K3 risk in substation construction projects in Maluku and Papua is the most allocated risk shared between the owner and the contractor. The most K3 risk response is by holding and partially allocating to the owner by transferring. Recommendations for mitigation of K3 risks in substation construction projects in Maluku and Papua are by preparing procedures for work steps/related documents that are jointly supervised between the owner and owner. Then it is necessary to form an organization related to K3 that will be responsible for emergencies, work accidents and monthly reporting to the local Manpower Office.

Abstract

Clean water is one of the important aspects that must be prioritized in urban planning. The higher the standard of living of the community, the need for clean water will also increase. However, the fulfillment of adequate clean water needs in Supiori Regency is still not optimal. Based on the Minister of Public Works Regulation No. 14/2010, the coverage of drinking water services in Supiori Regency is classified as poor, with a clean water service level of less than 50%. Optimization efforts are needed to optimize and distribute clean water services in Supiori Regency meet the target of clean water services and create a sustainable community life. The research method uses three types of analysis. First, the ratio of clean water services in the settlements of Supiori Regency was analyzed using a calculation method that refers to the standard of clean water needs and availability. Second, the analysis of clean water services was conducted based on community perceptions. Third, this study analyzed the factors that influence clean water services using multiple linear regression. Descriptive analysis was used to identify optimization steps. The results showed that the ratio of clean water services in South Supiori District only reached 30.38%, while in East Supiori District, it was lower, at 19.78%. Based on community perceptions, 93% of the population in South Supiori District and 75% in East Supiori District have not used the Water Supply System. Regression analysis shows that in Supiori Selatan District, factors affecting clean water services include pipe distance, community participation, and number of family members. In East Supiori District, the influencing factors are pipe distance, management, and maintenance of clean water. So, there are optimization efforts that can be done, among others, through mapping services based on regional conditions. For areas that are difficult to reach by SPAM services, the community can utilize the nearest water source to meet their clean water needs independently.

Abstract

This study was conducted to determine the existence of subsurface aquifers and the distribution of groundwater-surface depth in Jayawijaya Regency, Mountainous Papua Province. The background of this research is the need for optimal groundwater management in areas with high topography such as Wamena City. The method used was a geophysical survey with the Wenner-Schlumberger configuration resistivity geoelectric technique to identify the aquifer layer. Primary data was obtained through direct measurements using geoelectric devices and GPS, while secondary data was obtained from related literature. The results showed that there were free aquifers with a depth of 25-105 meters and depressed aquifers at a depth of 145-270 meters in various research locations. The distribution of this aquifer is highly dependent on local geological conditions, with the availability of groundwater quite high in some areas and minimal in other areas such as Kampung Sabulama and Wasawa. In conclusion, the resistivity geoelectric method is effective for mapping the distribution of aquifers, which can further be used as a basis for groundwater management in the study area.
