Comparison of inflammatory mediator cytokine responses to inactivated virus platform COVID-19 vaccines between elderly and young adult populations

The coronavirus disease 2019 (COVID-19) pandemic has encouraged global vaccine research, yet vaccine effectiveness in the elderly remains a concern due to immunosenescence. The aim of this study was to compare the cytokine response elicited by an inactivated virus-based COVID-19 vaccine between elderly and young adults, focusing on key cytokines involved in cellular and humoral immunity: tumor necrosis factor-alpha (TNF-α), interleukin (IL)-2, IL-6, IL-10, and interferon-gamma (IFN-γ). A cross-sectional study was conducted in the Jakarta-Bogor region of Indonesia from January 2023 to December 2023. The study population was divided into two age cohorts: elderly (60−85 years) and younger adults (30−40 years). Blood samples were collected twice, after the first booster dose and four weeks after the second booster dose. Serum cytokine concentrations were measured using Luminex assays with microparticles conjugated to monoclonal antibodies against TNF-α, IL-2, IL-6, IL-10, and IFN-γ. Comparisons of the cytokine levels were conducted using Student’s t-tests or Mann-Whitney U tests as appropriate. A total of 74 individuals were included, with 37 each in the elderly and young adult groups. The results showed significant differences in cytokine responses between the two age groups. After the first booster, the levels of IL-6 and IFN-γ were significantly higher in young adults compared to the elderly. After the second booster, the levels of IL-6 were still significantly higher in the young adult group compared to the elderly group (p=0.001). Data indicated that after the second booster dose, the levels of TNF-α increased significantly in the young adult group only (p=0.004), while the levels of IL-2 (p=0.040) and IFN-γ (p=0.006) increased in the elderly group only compared to after the first dose. IL-10 levels increased in both groups (both had p=0.020). This study highlights that young adults had stronger pro-inflammatory responses, while the elderly relied more on IL-2 and IFN-γ for T-cell immunity, suggesting the need for vaccination strategies for the elderly to optimize immune responses.

The new insight of tectonic setting in Sunda–Banda transition zone using tomography seismic. Case study: 7.1 M deep earthquake 29 August 2023

Abstract The Sunda–Banda arc transition zone features the collision of the Indo-Australian oceanic plate and the Australian continent, resulting in intricate geological and geodynamic conditions. Tectonic activity in this region is shaped by the convergence of multiple major plates, including the Indo-Australian oceanic plate and the Eurasian plate. The crustal structure along the Sunda–Banda arc transition zone is complex and influenced by various factors such as subduction, continental collision, and volcanic activity. The tectonic complexity of the region in eastern Indonesia makes it an interesting area for study. In this research, International Seismological Centre-Engdahl-van der Hilst-Buland catalogue data from 1964 to 2020 were used, which include recorded information on 69.705 earthquake events from 1.185 recording stations and consist of 2.943.974 P phases. Resolution testing was performed using various velocity grids, and optimal results were obtained with a medium resolution of ∼100 km × 100 km × 80 km for the inversion process. The tomographic inversion analysis provided valuable insights into subsurface structures within Earth’s crust and mantle up to a depth of approximately 750 km. The occurrence of deep earthquakes in the study area has provided valuable insights into complex dynamics associated with subduction and plate tectonics. The results of the tomographic inversion analysis reveal that earthquakes are concentrated in areas with high-velocity anomalies, indicating intense tectonic activity near the subduction zone. This study offers the perspective on the structural complexities and earthquake origins in the Sunda–Banda arc transition zone following the 2023 Mw 7.1 Bali Sea earthquake, which occurred on August 29, 2023, at 02:55:32 UTC + 7, approximately 163 km northeast of Lombok, Indonesia. This earthquake was caused by slab pull activity from the Australian Plate and involved a combination of downward and oblique-normal movement. These characteristics indicate the convergence and interaction between tectonic plates in the subduction process occurring in the Bali Sea area. As a result, there have been frequent occurrences of various tectonic and volcanic activities including earthquakes of different magnitudes. These results highlight the significance of the high-velocity anomaly connected to this occurrence, offering valuable insights into seismic behaviour and tectonic phenomena in the region. The findings of this study indicate that the deep earthquakes in the Bali Sea may be induced by faulting due to the transformation of metastable olivine into denser spinel at significant depths, along with shear instability caused by phase transitions within Earth’s mantle layers. This theory proposes that stress-induced changes in phase can initiate shear instabilities and subsequently lead to deep earthquakes.

The Key Success Factor for Sustainable Rural Tourism Development in Madura Using Integration of the IPA-Kano Model

The momentum for the rise of global tourism after the COVID-19 pandemic has become an opportunity for developing local tourism and Indonesia's creative economy. One of the promising tourism regions in Indonesia is Madura. The tourism potentials on the island of Madura are historical, religious, natural, and cultural. Unfortunately, Madura's tourism potential has not been fully utilized, and as a result, the benefits have not emerged to strengthen the Madurese community's economy. In addition, tourism development directions are also partial without looking at environmental sustainability, community welfare, and other social aspects. Therefore, this research was conducted to determine the key success factors of sustainable tourism by integrating the Important-Performance Analysis method with the Kano model. This study was conducted in Sampang, Madura, specifically in a tourist village called Bira Tengah. The result of the study is that the tourist village should adopt key success factors such as leading to maintaining the destination environment, improving the contribution of tourists and local communities in area conservation, increasing the competitiveness of tourist destinations, conducting more intensive tourism promotions, creating fun tourism activities, increasing participation of the community and stakeholders of tourist villages, using local and environmentally friendly materials, improving the cleanliness of destinations, disseminating local cultural information and increasing employment opportunities. The cultural factors are a highlight in improving sustainable tourism performance. In addition, to enhance tourism performance, it needs to benchmark with developed and autonomous tourist villages that have demonstrated success in sustainable tourism.

Thermal Characteristics of the Extreme Cases of Tropopause Over the Tropics

ABSTRACTThe anomalous variability of extreme cases of the tropical tropopause provides insight into the stratosphere‐troposphere exchange process crucial for understanding climate change. The present study analyses the extreme variability of the tropopause and its thermal structure over the tropics using GPS radio occultation data over the period 2006–2019. The extremely cold and warm tropopauses and extremely high and low tropopauses are identified based on the cold point tropopause temperature and height, respectively, when their values exceed two standard deviations with respect to their climatological means. The analyses revealed frequent occurrence of extreme cases of tropopause over the Atlantic Ocean compared to the Western Pacific Ocean. Individually, extremely warm and low cases occur more frequently over the subtropics, while extremely cold and high cases occur frequently over the deep tropics. These extreme cases pose different thermal structures bounded within the extremely low and high tropopauses throughout the tropics. The height difference between the extremely high and low tropopause cases is wider over the Atlantic Ocean and adjoining areas compared to the western Pacific Ocean. The temperature difference between the extremely warm and cold tropopause cases is higher in the Atlantic, Central Pacific, and Indonesian regions compared to the American, Indian Ocean, and western Pacific Ocean regions. The relationship between the El Niño Southern Oscillation (ENSO) phases and extreme tropopause cases is also investigated which reveals a higher occurrence of extremely high tropopause cases during the El Niño phase while low tropopause cases during the La Niña phase. Our analysis also revealed the thermal patterns of the extreme cases characterising colder and sharper tropopause over the convective regions compared to subsidence regions.

Design and Construction Of A River Water Level Monitoring System Based On IOT (Internet Of Things)

The prolonged rainy season due to extreme weather changes that occur in various regions in Indonesia means that people must be more alert to flood disasters. Many losses occurred due to flood disasters. Therefore, an effort is needed to minimize these losses, namely by creating a river level monitoring system based on IoT (Internet of Things). This river water level detection system uses an ultrasonic sensor (water level sensor), NodeMCU ESP8266 to read data and send it via the telegram application and a buzzer which functions to make a sound when the sensor detects water and the potential for flooding. The system will work automatically when water touches the sensor and sends flood detection status information via the telegram application. This system can be implemented in flood-prone areas. With this monitoring system, river water levels can be monitored and the risk of flooding can be reduced.

Rethinking Local Government Asset Management in Indonesia: Governance, Planning, and Policy Evaluation

Effective asset management is essential for enhancing operational efficiency and achieving sustainable development within local governments in Indonesia. This study explores key challenges in asset management, focusing on governance, planning, and policy evaluation. Several critical issues are identified: fragmented governance, insufficient transparency and coordination, outdated asset inventories, and misalignment between asset management practices and broader development goals. Policy evaluation mechanisms are also inadequate, failing to measure asset utilisation effectively. These challenges lead to inefficiencies in resource allocation, underutilisation of assets, and missed opportunities for local economic growth. The findings align with Sustainable Development Goals (SDGs), particularly SDG 11 (Sustainable Cities and Communities), which promotes efficient resource use, and SDG 9 (Industry, Innovation, and Infrastructure), which supports enhanced infrastructure management. Addressing these goals enables local governments to align asset management strategies with broader sustainability objectives, fostering equitable growth and long-term development. Through a qualitative literature review, this study analyses data from government reports and prior research to highlight these challenges and propose solutions. An integrated approach—aligning governance frameworks, improving asset management planning, and strengthening policy evaluation—can overcome the identified barriers. By adopting this model, local governments can optimise asset management, leading to improved efficiency, better resource utilisation, and sustainable development. Future research should explore applying this framework across regions in Indonesia to validate its effectiveness.

Peran Masyarakat Lokal dalam Pengelolaan Daya Tarik Wisata Alam Arung Jeram Papulangi Kabupaten Gorontalo Uatar

Currently tourism activities in Indonesia are experiencing rapid development, this can be seen from the various regions in Indonesia developing tourist destinations in their respective regions. In Law Number 10 of 2009 which states that the existence of tourist attractions in an area will be very profitable, including improving people's standard of living, expanding employment opportunities, increasing Regional Original Income (PAD), then increasing love for the environment and preserving nature and local culture. The existence of the tourism sector in a region can have both positive and negative impacts. However, basically it depends on the management and management of tourism played by all stakeholders from government, private sector and community elements in the area. Achieving the goals and mission of good, sustainable and environmentally friendly tourism development will be possible if the achievement process can be carried out through good tourism governance. (good tourism governance). The principle of implementing good tourism governance is the coordination and synchronization of programs between existing stakeholders and the involvement of synergistic (integrated and mutually reinforcing) active participation between the government, private sector or tourism industry and the relevant local communities.

Digital health divide in Indonesia: evidence from national-level data

Abstract Indonesia is a country in south-east Asia with a diverse population and context underlined by its geographical condition as an archipelagic country. Due to closer proximity to the capital, the Western regions (e.g., provinces in Sumatra and Java islands) are relatively more developed than the central and eastern parts of Indonesia (e.g., Nusa Tenggara, Sulawesi, and Papua). In the last few years, the country started to embrace digital transformation for public services including the health sector. Accelerated by the COVID-19 pandemic, a proliferation of digital health services through for example the use of telehealth and health apps is now considered important to improve access and availability of health services, especially among marginalized and hard-to-reach populations. Nonetheless, the difference in access to information and technology infrastructure and services as well as in the level of digital literacy across different regions in Indonesia may perpetuate the existing inequity in access to health services. In 2022, data from the Indonesian Central Bureau of Statistics showed that the level of internet access in Indonesia’s capital Jakarta has reached 85%, while the level in the eastern part of Indonesia (i.e., Papua) is only 26%. Similarly, the level of internet access in the Western provinces tend to be higher than their Eastern counterparts. Additionally, a survey performed by the Ministry of Communication and Informatics to assess the level of digital literacy in Indonesia shows that 85% out of 10,000 respondents accessed the internet through smartphones. However, almost all respondents encounter problems when accessing the internet, especially regarding network quality which causes unstable and frequent connections disconnected. In addition, the level of digital literacy varies across different regions, with the Western region performing better than other regions (e.g., digital literacy index of 3.64 in Yogyakarta vs 3.55 in Papua in 2022).

Regional financial potential after the enactment of the law on the financial relations between central government and regional governments in Indonesia

The implementation of government decentralization in Indonesia is facing regulatory problems for autonomous regions’ financing sources. Therefore, attention to regional finance is increasingly needed given that autonomous regions are required to carry out various central government interests in addition to their affairs. This leads to a split of power over financing development policy by the regional government. However, this does not mean that the local government’s financial needs must be free from the central government’s intervention. This study briefly compares financing regional autonomy in Indonesia, France, Germany and Thailand. The results show that the distribution of financial resources between the central government and regional governments is inconsistent with Article 18A section 2 of Law No.1/2022. The results also show that the provisions of various sources of taxation and levy have not met the financial needs of regions in Indonesia. Financial balance in the form of Natural Resources Production Sharing Fund from various natural resources owned by regions that only share unrenewable resources such as mining excavated materials remains unequally distributed between regions that have natural resources.
