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.

Abstract

Kampung Maribu, Kabupaten Jayapura, Papua, memiliki potensi besar dalam pengembangan pinang (Areca catechu) sebagai komoditas lokal yang bernilai ekonomi. Namun, pemanfaatannya selama ini masih terbatas pada penjualan dalam bentuk mentah dan konsumsi tradisional sehingga belum memberikan nilai tambah yang signifikan. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan pemuda Karang Taruna Maribu dalam mengolah pinang menjadi produk pangan berupa permen. Metode pelaksanaan dilakukan melalui In-Service Training (IST) untuk memberikan pemahaman konseptual mengenai potensi pinang, higienitas dasar, bahan, serta proses produksi, dan On-Service Training (OST) berupa praktik langsung pembuatan permen pinang. Evaluasi dilakukan dengan desain one-group pretest–posttest menggunakan instrumen berupa soal pengetahuan dan angket kepuasan peserta. Hasil menunjukkan adanya peningkatan signifikan, di mana lebih dari 95% peserta menyatakan memahami bahan, langkah, serta proses pembuatan permen setelah pelatihan, dibandingkan dengan pengetahuan awal yang masih rendah (hanya 28–36%). Tingkat presensi peserta mencapai lebih dari 90%, dengan mayoritas berasal dari kelompok usia produktif (21–30 tahun) dan didominasi perempuan (80%). Temuan ini menegaskan bahwa pelatihan pembuatan permen pinang efektif dalam meningkatkan kapasitas masyarakat sekaligus membuka peluang pengembangan wirausaha berbasis pangan lokal yang berkelanjutan.

Abstract

Nabire Regency, located in Central Papua Province, is among the regions highly vulnerable to flooding due to persistent and intense rainfall throughout the year. Flood disasters generate multifaceted impacts, including economic losses caused by property damage and business disruptions, social issues such as health problems and psychological distress, and environmental degradation in the form of erosion and water pollution. This study aims to formulate mitigation and adaptation strategies for flood disasters by analyzing community perceptions and evaluating existing measures. The research employs the Likert Scale method to assess public perception and the Analytic Hierarchy Process (AHP) approach to determine the most effective strategies for mitigation and adaptation. The findings reveal that the community possesses a solid understanding of flood events and acknowledges the necessity of implementing mitigation and adaptation efforts. The AHP analysis indicates that the Regional Disaster Management Agency (BPBD) plays a crucial role in executing flood management strategies, particularly within the environmental management domain. The primary recommended strategy is environmental planning and management. Through an integrated and sustainable approach, flood risks are expected to be mitigated more effectively, minimizing adverse impacts on both the community and the environment in Nabire Regency.

Abstract

Nabire Regency, Central Papua Province, has a high vulnerability to flooding due to significant rainfall intensity. Risk analysis was conducted using the Analytical Hierarchy Process (AHP) method to determine the priority of factors causing flooding, including hydrological aspects, land use, infrastructure, and socio-economic impacts in a systematic manner. The results of this study indicate that the analysis of public perception of flooding disasters was conducted by modeling data using a Likert scale, which was processed computationally to generate patterns of public perception. The Analytical Hierarchy Process (AHP) method was used to determine the priority of data-based mitigation strategies. The results confirm that BPBD plays a dominant role in flood risk management through the integration of adaptive and sustainable environmental information systems.
