Abstract

The development of an area will cause the demand for water to continue to increase along with thepopulation growth rate. The fulfillment of food needs and the activities of the population are always closely relatedto the need for water. The demands are unavoidable but must be predicted and planned for optimal utilization.The tendency that often occurs is the imbalance between water availability and water demand. To achieve abalance between water demand and availability in the future, efforts are needed to assess the components of rawwater availability and demand as clean water sources. The source of clean water for the people of Bonggo District, Sarmi Regency, comes from borehole pumps,shallow wells (pumps), and rainwater. The analysis results on the need for domestic and non-domestic clean waterin the Bonggo District in 2023 show a total requirement of 210.38 liters/day or 0.0024 m3/second. The need forclean water is expected to increase by 2043, with the total requirement for domestic and non-domestic clean waterreaching 285,820 liters/day or 0.0033 m3/second. The availability and need for clean water sourced from rawwater that can be utilized as clean water comes from pump bore wells as a suitable raw water source. In terms ofquantity, it is available 24 hours a day and throughout the year. The investigation results of the pump bore wellraw water source meet the clean water quality requirements according to Government Regulation No. 82 of 2001,Level II. This is supported by groundwater, obtained through the analysis of geological conditions, land cover,morphology, and river flow, which have a high to very high groundwater potential score, located in the northernpart of Bonggo District. Economically, in terms of quantity, rainwater can be used as clean water due to its sufficientavailability, with high rainfall (104,775 mm/year) and year-round service (continuity), and in terms of quality, theresults of rainwater quality tests meet the clean water standards according to quality standards.

Abstract

Fishery waste is a problem that is very disturbing to the community because it causes strong odors, dirty views, and reduces water quality. Apart from having a negative impact, fishery waste still contains components needed for plant growth, such as nitrogen (N), phosphorus (P), and potassium (K). Therefore, it is essential to conduct community service activities for POKBAKER that involve the conversion of fishery waste into liquid organic fertilizer (POC). The aim of carrying out service activities is to provide understanding to participants through lectures and practical activities in making fertilizer from fisheries. The implementation methods expressed are three, namely pre-preparation, socialization activities (pre-test, lecture, post-test), and practical activities. The materials used in practical activities are fishery waste (gills and offal), EM4, molasses, and rice washing water. The results show that the percentage of answers to the six pre-test questions given ranges from 53-100 percent, while the percentage of the eight post-test questions given ranges from 93-100 percent. So, the conclusion is that this activity can increase the knowledge and understanding of the Fishery Waste Processing Group (POKBAPER) from 53 percent to 90 percent. Participants have the ability to plant liquid organic fertilizer from fishery waste.

Abstract

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.

Abstract

This research investigates the effects of incorporating potassium nitrate (KNO₃) into coconut shell charcoal briquettes, emphasizing their physical and chemical characteristics. Briquettes were manufactured utilizing coconut shell charcoal powder, tapioca flour as a binder, and different concentrations of KNO₃ (0% and 10%) as an additive. The aim was to assess the impact of KNO₃ incorporation on the water content, ash content, volatile matter, fixed carbon, calorific value, and density of the briquettes. The findings indicated that incorporating KNO₃ resulted in elevated water and ash content, adversely affecting combustion efficiency. Briquettes with increased water content demonstrated reduced mechanical strength and inferior combustion performance. The addition of KNO₃ led to an increased volatile matter content, facilitating ignition of the briquettes while simultaneously resulting in higher smoke emissions. The addition of KNO₃ resulted in a decrease in fixed carbon content, which subsequently lowered the calorific value of the briquettes. The formulation without KNO₃ produced the densest briquette, suggesting that including KNO₃ reduced the briquette density. The inclusion of KNO₃ enhances ignition characteristics; however, it concurrently diminishes the briquettes' overall quality regarding combustion efficiency and calorific value. The Briquette B_1 exhibited the highest results in this investigation, with water content, ash content, volatile matter, fixed carbon content, calorific value, and density values of 4.97%, 1.87%, 17.25%, 80.88%, 7014 Cal/g, and 0.90 g/cm³, respectively.
