Cherax pulverulentus, a new freshwater crayfish (Decapoda: Parastacidae) from Southwest Papua Province, Indonesia

Cherax pulverulentus sp. nov. is a moderately-sized burrowing freshwater crayfish endemic to the streams west of the Ayamaru Lake in Bird's Head Peninsula (Framu Subdistrict, Southwest Papua Province), the Indonesian part of New Guinea. Although this species has been exploited in the ornamental aquarium trade at least for 21 years, it has not been formally named until now. Its commonly used commercial names in the pet trade are: “Hoa Creek”, “Irian Jaya”, or “Blue Moon” crayfish, but these names are also used for other more bluish or pinkish species of Cherax. Cherax pulverulentus sp. nov. is genetically and morphologically most similar to Cherax pulcher Lukhaup, 2015, but both species may be distinguished by several morphological characteristics and DNA sequence divergence, which support C. pulverulentus sp. nov. as a valid species.

Fertilization rate of crossbreeding cattle using sexing and conventional semen in different seasons in South Papua

Objective: Fertilization rate of artificially inseminated cows using sexed and conventional semen in different seasons in South Papua. Materials and Methods: Eighty crossbred cows aged 4–4.5 years with body condition score 3.8 were divided into groups A (summer = 40 cows) and B (rainy season = 40 cows). Each cow in each season was artificial insemination (AI) using sexed frozen semen and conventional semen. Frozen semen was evaluated for post-thawing motility (PTM), cell membrane integrity, and acrosome damage before synchronization using 5 ml PGF2α plus vitamin E. Using a visual gun, we identified cows in estrus on days 4–7 post-synchronization. Pregnancy of cows was detected using N5Vet ultrasound on days 35 and 55. The interaction between season, semen type, and fertilization level was analyzed using standard error and two-way ANOVA, assisted by SPSS 21 software. Results: The wet season Temperature-Humidity Index (THI) level averaged 77.12 ± 1.19, and the summer season THI level averaged 82.67 ± 1.25. PTM quality averaged 60%–65%, viability 61%– 71%, sperm membrane integrity 62%–65%, and acrosome integrity 88%–91%. Conception rates (CR) value of rainy season (p < 0.05) with summer season. In addition, the services per conception (S/C) value in the rainy season (p > 0.05) is the same as in the summer. This study’s S/C and CR values were within normal limits, and the pregnancy rate reached 65%–86%. Pregnancy detection can be observed on day 35, and the fetal heartbeat is visible. Conclusion: Post-AI fertilization using conventional semen was better in all seasons. The double dose of sexed semen can increase the fertilization rate in summer.

Susun Kata Tingkatkan Literasi: Pelatihan Kreatif bagi Anak-Anak Kampung Onggatmit

The quality of education in Indonesia is still low, one of the causes is the low ability to read, in this case reading literacy and critical thinking skills, especially in children. This is based on data that Papua Province ranks last with a score of 19.90 which shows a very low category. Onggatmit Village is one of the villages in Merauke, South Papua Province with many children who are still unable to read and even recognize letters and numbers. Basic literacy needs to be applied early in primary school-age children when brain development can still be shaped. Due to conditions that cannot gain knowledge in school, one of the activities that can be done to improve basic literacy is to conduct basic literacy training for children in Onggatmit Village with word stacking games. This service activity was carried out in four stages, namely survey, socialization, training and monitoring. The results of this service activity run smoothly and can improve basic literacy skills carried out with word stacking games for children in Onggatmit Village.

Integrating Systems Thinking and Islamic Principles for Sustainable Development: A Case Study of South Papua, Indonesia

This study explores the use of a systems thinking approach to analyze the interactions between economic, social, and environmental factors in achieving sustainable development in South Papua, a newly established province in Indonesia. The research aims to address the primary issue of fragmented policy approaches that fail to account for long-term impacts and intersectoral linkages. Using a qualitative exploratory design, primary data was collected through Focus Group Discussions (FGDs) with local stakeholders, while secondary data was obtained from government reports and academic literature. Thematic analysis and causal loop diagrams (CLD) were employed to identify dynamic interactions and leverage points for policy interventions. Key findings highlight that economic growth is contingent upon sustainable natural resource management and human resource development, with feedback loops revealing the potential for synergies and trade-offs between Sustainable Development Goals (SDGs). System archetypes such as "Shifting the Burden" and "Tragedy of the Commons" were identified, underscoring the need for policies that consider long-term impacts and equitable resource distribution. The integration of Islamic principles of justice and responsibility offers additional guidance for addressing these systemic challenges. The study concludes by providing holistic policy recommendations for sustainable development in South Papua, contributing both to academic literature and practical policymaking.

Evaluasi Pemekaran 6 Provinsi di Papua: Studi Pandangan Tokoh Adat Papua

The expansion policy regulated in Law Number 2 of 2021 mandates the formation of three new provinces in Papua, namely South Papua, Central Papua, and Mountainous Papua. They believe that expansion will bring more attention and resources to areas that have been neglected. The purpose of this study is to look at the impact of provincial expansion in Papua from the perspective of indigenous leaders, given that this policy has created six new provinces in the country. As part of the Indonesia government's efforts to improve administrative efficiency and accelerate development, these changes have generated a lot of response from the community, especially from indigenous Papuan leaders who have an important role in the country's social and cultural structure. This study uses a qualitative approach with literature review to reveal the subjective views and experiences of indigenous leaders related to provincial expansion. The results of the study show that traditional leaders support and oppose this expansion policy. Support comes from those who believe that expansion can accelerate progress and well-being, while objections stem from concerns that it could disrupt social and cultural stability. This research helps to understand the impact of expansion from the perspective of indigenous leaders, emphasizes that cultural and social aspects must be considered when making expansion policies, and suggests that an inclusive and local wisdom-based approach should be applied in Papua's development process.

Hands Across Australia’s Land Border

Drawing on Indonesian and Dutch newspapers, this article describes how the Australian people and their political leaders were presented in contradictory ways to readers during the West New Guinea dispute. Particularly from 1949 to 1967, at the height of the dispute between the Netherlands and Indonesia over West New Guinea/Irian Barat, Dutch newspapers focused on the nature of Australian colonialism in an increasingly critical manner. The Indonesian press expected Australia – a supporter of its independence struggle and donor of education aid – to sympathise with its claim to the territory of Irian Barat. Sensitive to any signs that Australia sided with the Dutch or that it feared Indonesian ambitions in the region, the Indonesian press was at first displeased by Australia’s policy of ‘neutrality’ and then satisfied that the Australian government would not interfere.

CONTRIBUTION OF JOB STRESS IN MEDIATING ASPECTS AFFECTING WORK FATIGUE OF MINISTRY OF RELIGIOUS AFFAIRS EMPLOYEES IN THE SOUTH PAPUA PROVINCE REGION

Employees working for the Ministry of Religion in the South Papua Province have a range of tasks related to community service in religious affairs. The demanding workload in this role calls for extra effort from the employees. This research aims to explore how work stress acts as a mediator in the relationship between leadership style, workload, and income adequacy with work fatigue among Ministry of Religion employees in the South Papua Province. Data was collected through a survey involving 153 participants. The findings from the structural equation modeling analysis reveal that leadership style has a significant negative impact on work stress, while workload has a significant positive impact on work stress. However, income adequacy does not seem to affect work stress. Moreover, leadership style negatively impacts work fatigue, whereas workload has a positive impact on work fatigue. Income adequacy, on the other hand, does not have a significant impact on work fatigue. The study ultimately concludes that work stress plays a role in mediating the relationship between leadership style and workload with work fatigue. However, work stress does not mediate the effect of income adequacy on job burnout.

The Influence of Vehicles Parking on the Roadside as Reduction of Lane Width on Traffic Performance

The city of Poso is experiencing rapid economic growth, attracting many newcomers and developing various commercial facilities along its streets. This study analyzes traffic performance on three road sections in Poso City: Jl. Pulau Irian Jaya (District Road), Jl. Pulau Sumatera (National Road), and Jl. Kasintuwu (Provincial Road), focusing on the impact of on-street parking as a side friction and lane width reduction on road capacity and degree of saturation (DS). The methods used are MKJI 1997 and PKJI 2023. The study results indicate that road capacity decreases and DS increases significantly when using the PKJI 2023 method compared to MKJI 1997. Jl. Pulau Irian Jaya experienced an increase in DS from 0.372 to 0.410 (side friction) and from 0.874 to 0.94 (lane width reduction). Jl. Pulau Sumatera showed an increase in DS from 0.716 to 0.776 (side friction) and from 0.75 to 0.84 (lane width reduction). Meanwhile, Jl. Kasintuwu showed an increase in DS from 0.114 to 0.118 (side friction) and from 0.20 to 0.21 (lane width reduction). These results suggest that the PKJI 2023 method provides a more conservative estimate, indicating a more significant decline in traffic performance compared to MKJI 1997.

Assessing the Potential of Biomass Power Generation for Renewable Energy Transition in South Papua Province, Indonesia

This study aims to explore the potential for biomass-based power plant to accelerate the development of renewable energy to replace the role of fossil energy in Merauke district, South Papua Province. The method used in this study is, first, to collect data and analyze the load on the grid system and the portion of the energy mix as well as the availability of woody biomass from forest areas by making a simulation of the development of a 2 x 12 MW Biomass Power Plant. Second, by conducting experiments to obtain woodchip conversion, as the fuel of the Biomass Power Plant, from the wood log and conversion from Biomass Power Plant capacity to the required biomass plantation area. The results provide an overview of the big potency for developing biomass-based power generation by utilizing biomass from the local industrial plantation forest and show the energy transition towards energy independence. This study can be useful for policy makers and opportunities for entrepreneurs or suppliers of wood biomass, as well. For the future, in terms of fuel efficiency, it is necessary to reduce the plantation area as a source of biomass for power plants by reducing the moisture content of the woodchip to increase the calorific value and utilizing the forest residue. Furthermore, the comparison cost study between fossil power plant and biomass power plant, as well as the strategy for preserving the plantation to ensure a steady biomass supply is conducted.

A description of lineage 1 Mycobacterium tuberculosis from papua, Indonesia

Indonesia has the third highest number of tuberculosis (TB) patients infected with Mycobacterium tuberculosis (MTB) Lineage 1 (L1). Most of these MTB L1 cases can be found in Indonesia's remote easternmost province of Papua, one of Indonesia's most underdeveloped provinces with a particularly high burden for TB. In this study, we sequenced and described 42 MTB L1 isolates from a well-characterized cohort of patients. We found a genetically diverse MTB L1 population with no association between pathogen genetic relatedness and place of residence or pathogen genetic relatedness and patient ethnicity, which could reflect mixing between different locales and ethnicities or our low sampling fraction. Only a small number showed genetic variants associated with drug resistance (5/42, 11.9 %), probably due to a lack of effective treatment programs. The Papuan isolates showed similarities to other Island Southeast Asian Countries due to the high proportion of L1.2.1.2.1 (30/42, 71.4 %), especially East Timor and the Philippines. This study fills a research gap of MTB L1 in Indonesian Papua and should serve as a stepping stone for further research in the region.

Annual and Interannual Rainfall Variability in Indonesia Using Empirical Orthogonal Function (EOF) Analysis and Its Response to Ocean-Atmosphere Dynamics

We investigate rainfall variability in Indonesia using the Empirical Orthogonal Function (EOF) method. The analysis starts by taking three main modes of EOF results, namely EOF1, EOF2, and EOF3. The EOF1 region is southern Indonesia, from southern Sumatra to Timor Island, parts of Kalimantan, parts of Sulawesi, and parts of Irian Jaya. The EOF2 region is located in northwestern Indonesia and includes the northern part of Sumatra and the northwestern part of Kalimantan. The EOF3 region covers Maluku. This study aims to analyze the annual and inter-annual variability of rainfall in anticipation of the threat of hydrometeorological disasters. Based on the correlation value of the principal component (PC) with the dipole mode index (DMI) and Niño3.4 index, it has a period similar to El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). Rainfall in Indonesia is very sensitive to sea surface temperature (SST) in the southeastern Indian Ocean and the central Pacific Ocean, which means that rainfall patterns in Indonesia can change significantly if SST in the region changes.
