Green Open Space (GOS) is an essential element in urban spatial planning that functions to maintain air quality and ecosystem balance. This research aims to analyze the influence of GOS on the concentration levels of Carbon Dioxide (CO2​) in the urban area of Jayapura City. The study locations were focused on two areas with distinct characteristics: Jalan Sam Ratulangi, which has high vegetation coverage, and Jalan Percetakan, which is dominated by built-up areas and dense commercial activity. The methods used include spatial analysis utilizing Landsat 8 satellite imagery Band 4 (Red) and Band 5 (NIR) to calculate the NDVI (Normalized Difference Vegetation Index), a vegetation time series analysis from 2019–2024, and direct CO2​ concentration measurements taken at three different times (morning, noon, afternoon). The data was processed using ArcGIS with the Kriging Interpolation method to generate spatial distribution maps of CO2​ in both locations. The results show that Jalan Sam Ratulangi has a GOS area of 6.13 ha (94%), while Jalan Percetakan has only 2.95 ha (31%). This difference significantly impacts CO2​ levels, with an average concentration of 484 ppm at Sam Ratulangi, which is lower than Percetakan's average of 567 ppm. The highest CO2​​ value at Percetakan reached 649 ppm during the afternoon, whereas Sam Ratulangi recorded only 488 ppm. This study proves that the wider and healthier the GOS, the lower the CO2​​ concentration detected. These results demonstrate that vegetation plays a significant role in reducing carbon emissions in urban areas, supporting the crucial role of GOS in maintaining air quality and supporting sustainable urban development in Jayapura City.

Wildfires in Los Angeles are a phenomenon that can be analyzed from two main perspectives: science and religion. From a scientific standpoint, these fires are triggered by a combination of natural factors, such as the Santa Ana winds that bring hot and dry air, and climate change, which extends drought periods and increases temperatures. However, human activities, including environmental exploitation, deforestation, and inadequate fire mitigation efforts, have exacerbated the situation. From an Islamic perspective, natural disasters can be seen as tests, warnings, or consequences of human negligence in maintaining environmental balance, as mentioned in the Qur'an (Surah Ar-Rum: 41). This study highlights that wildfires are not merely natural occurrences but also have spiritual dimensions. Islam emphasizes that humans are entrusted as stewards of the earth, responsible for preserving nature rather than passively accepting disasters. Therefore, the best approach to addressing wildfires is to integrate scientific understanding with religious values. Proposed solutions include science-based prevention efforts, such as sustainable forest management and fire mitigation policies, as well as spiritual awareness to appreciate and safeguard nature as a divine trust. By understanding the relationship between science and religion, humanity can take greater responsibility in disaster response and establish a more balanced and sustainable way of life.

The Indonesian government has been actively combating illegal fishing practices at sea because they harm the country and reduce fish populations. However, attention to freshwater fisheries, especially endemic fish, is still limited. In fact, endemic fish play an important role in aquatic ecosystems and local culture. Fish resource conservation aims to protect, preserve, and utilize fish and their ecosystems and genetic diversity so that their existence and availability remain sustainable. The diversity of freshwater fish in Indonesia faces serious threats from human activities. The main factor is the introduction of new species that grow uncontrollably, becoming pests and harming ecosystems and communities. In addition, overfishing and declining habitat quality further exacerbate the situation. These threats pose a risk of extinction for endemic fish. Therefore, conservation efforts need to be strengthened to maintain ecosystem balance and support the livelihoods of communities that depend on fish farming. Legal protection is an important aspect in addressing this issue. Law No. 31 of 2004 concerning Fisheries and Law No. 5 of 1990 concerning Conservation of Living Natural Resources and Ecosystems have provided a legal basis for fish resource management. However, their implementation and enforcement remain weak. This study uses a normative juridical approach with secondary legal materials, emphasizing the importance of improving the legal framework and more effective governance. Measurable, transparent, and sustainable conservation measures are needed to ensure the optimal utilization of fish resources. Thus, the sustainability of freshwater ecosystems and the welfare of communities that depend on endemic fish can be guaranteed.

Hand measurements are known to provide a good estimate of a person's height, which is particularly useful in the process of identifying human remains that are dismembered or separated due to various circumstances. Such conditions often occur during mass disasters, murders, airplane crashes, train collisions, and highway accidents. In forensic anthropology, hand length is one of the body measurements that can help estimate height when complete body parts are not available. This study aims to examine the relationship between hand length and height specifically in individuals from the Jambi Malay tribe, one of the ethnic groups in Indonesia. The research design used is analytic with a cross-sectional approach. The type of data used is primary data, obtained directly from 56 respondents belonging to the Jambi Malay tribe, both male and female. Statistical analysis showed that all independent variables — the length of the right and left hands, both in men and women, as well as without gender distinction — had a significant relationship with height. This is indicated by a P-value < 0.05 (P = 0.001). These results suggest that hand length can be a reliable predictor of height in this ethnic group. The study also highlights the importance of conducting further research involving other body parts and ethnic groups to support broader forensic identification efforts.
