Agar is the main medium used in microbiology laboratories to grow bacteria and fungi because of its ability to form stable gels that are not easily degraded by microorganisms. However, the availability of expensive commercial agar and dependence on imports is a challenge for small-scale laboratories. This literature study aims to review the potential of natural materials such as local seaweed (Gracilaria sp.), banana peels, cassava starch, and coconut pulp as alternative media for microorganism growth. The results of the study indicate that Gracilaria has the ability to form gels similar to commercial agar, while banana peels and cassava starch are rich in nutrients but require the addition of thickeners. The main challenge lies in the sterilization process and media consistency. The use of these materials can be a cheap and sustainable solution in the development of microbiology media based on local resources.  

Natural and non-natural disasters significantly disrupt healthcare systems, particularly obstetric and gynecological services, which are highly vulnerable to service interruptions and quality decline. Pregnant women, postpartum mothers, and newborns face an increased risk of complications and mortality without adequate medical care. Health professionals play a crucial role in ensuring the continuity of reproductive health services through the implementation of the Minimum Initial Service Package (MISP), emergency management, health education, and intersectoral coordination. However, challenges such as limited resources, psychological pressure, and lack of specialized training hinder optimal performance. Therefore, strengthening the capacity of healthcare workers, enhancing disaster preparedness, providing adequate logistics, and enacting supportive governmental policies are essential to maintain effective obstetric-gynecological care during crises. This literature review comprehensively discusses the role of health workers in ensuring reproductive health services in disaster settings as a strategy to improve access and service quality during emergencies.

The 1945 Constitution of the Republic of Indonesia states that every Indonesian citizen has the right to a clean and healthy living environment. Unsustainable development and exploitation of natural resources have led to a drastic decline in the quality of the living environment in Indonesia. This has resulted in environmental damage, such as pollution and loss of biodiversity. One important instrument in the effort to protect the environment is environmental law, which is regulated by Law Number 32 of 2009 concerning the Protection and Management of the Living Environment (Environmental Protection Law). Although the Environmental Protection Law provides a comprehensive legal framework, law enforcement in the field still faces several issues, such as limited resources and low legal awareness. In such situations, community participation can be strategically utilized to enhance the efficiency of environmental monitoring and law enforcement. The aim of this research is to descriptively examine the function of community participation in environmental law enforcement as regulated by the Environmental Protection Law, as well as to analyze how effective and challenging its implementation is.

Tarakan City, as the largest city in North Kalimantan Province, plays a strategic role as a center for economics, trade, and tourism. Good accessibility through its international airport and seaport makes Tarakan a major gateway to various destinations in North Kalimantan. This potential is supported by its rich natural resources and cultural heritage, as well as its position as a distribution hub for goods and services. However, the development of the tourism sector remains hampered by the limited availability of premium accommodation facilities that meet international standards, particularly for domestic and international tourists, as well as business travelers. This final project proposes the design of a four-star hotel in Tarakan City as a solution to increase the attractiveness and competitiveness of the tourism sector. The concept used is Neo-Vernacular Architecture, a design approach that combines traditional architectural values with modern needs and technology. This concept aims to maintain local identity, enrich the building's aesthetic qualities, and create comfortable spaces suited to the local tropical climate. During the design process, a thorough analysis of site conditions, climate characteristics, local cultural potential, and four-star hotel operational standards was conducted. The traditional architecture of the Baloy Mayo traditional house served as the primary inspiration, both in terms of form, decorative elements, and spatial philosophy, resulting in a design that is contextual and representative of Tidung culture as one of Tarakan's identities. The resulting design is expected to provide quality accommodation facilities that not only support the needs of tourists and business people, but also become a modern architectural icon that respects and preserves local culture. The presence of this hotel is expected to contribute to the development of the tourism industry and strengthen the image of Tarakan City as a leading destination in North Kalimantan.

This research aims to develop liquid organic fertilizer (LOF) made from goat livestock waste and paitan (Tithonia diversifolia) conducted in Makale, Tana Toraja Regency, from March to June 2025. This study aims to determine the response of cucumber plants to the application of LOF derived from the combination of goat livestock waste and paitan plants. Goat livestock waste contains macro nutrients such as nitrogen (N), phosphorus (P), and potassium (K), while paitan plants are green organic materials rich in nutrients and easily decomposed. The combination of both is expected to naturally improve soil fertility and optimally support the growth and yield of cucumber plants. The research method uses a Completely Randomized Design (CRD) with four different LOF concentration treatments and five replications. Parameters observed include plant height, number of leaves, stem diameter, number of flowers, number of fruits, and fruit weight per plant. The LOF production process is carried out through fermentation for 21 days with a ratio of goat livestock waste and paitan of 3:1, and the addition of EM4 as a microorganism activator. This research also aims to evaluate the effectiveness of LOF application on growth parameters (plant height, number of leaves) and yield (number and weight of fruits) of cucumber plants, and compare it with treatments without LOF or with inorganic fertilizers. The results of this research are expected to serve as a reference for local farmers in developing organic fertilizers based on local resources that are environmentally friendly, efficient, and sustainable to increase agricultural productivity in the Tana Toraja region.

The policy of granting Mining Business Licenses (IUP) to universities under Article 51A of the Minerba Bill raises legal, ethical, and sustainability concerns. This study applies a qualitative approach through literature review to examine the provision from the perspectives of Indonesian law and Islamic teachings. The findings reveal that allowing universities to manage mining permits risks diminishing their academic role, compromising scholarly independence, and fostering potential conflicts of interest. From the standpoint of positive law, this policy contradicts the precautionary principle, social justice, and educational objectives enshrined in the 1945 Constitution, the Higher Education Law, and the Environmental Protection Law. In Islamic thought, irresponsible exploitation of natural resources is classified as fasād (corruption), strictly prohibited, as reflected in Hadith No. 479 narrated by Bukhari. The study concludes by rejecting the provision and recommends repositioning universities as guardians of sustainability values rather than participants in extractive industries.

The South China Sea is a strategic water area connecting East Asia, the Pacific Ocean, and the Indian Ocean, and is the main route for around 30 percent of international trade shipping. This area is also rich in energy resources, such as natural gas and petroleum. However, in recent decades, the South China Sea has become the center of territorial disputes due to unilateral maritime claims by China through the Nine Dash Line principle which covers up to 90 percent and is contrary to the Law of the Sea. China even builds artificial islands equipped with military infrastructure, which increases tensions in the region. Through the approach of the realism paradigm, as well as the theory of complex regional security and maritime security as well as literature analysis, this article discusses the implications of China's artificial island construction on maritime security in Southeast Asia, especially for countries such as Vietnam, the Philippines, Malaysia, and Brunei Darussalam. This article emphasizes that China's actions have implications that greatly disrupt the stability of maritime security for countries in the region located in the South China Sea waters.

This paper explores how climate change has contributed to the armed conflict in Darfur, Sudan, by emphasizing the human security perspective. Prolonged drought, desertification, and resource scarcity have intensified tensions between farming and pastoralist communities. Using a case study method and the Human Security framework, this study finds that ecological stress acts as a threat multiplier in conflict-prone areas. Data from IPCC, SIPRI, and UNHCR reports highlight how environmental degradation worsens structural vulnerabilities and fuels horizontal violence. The analysis shows that climate change is not only an environmental issue but also a serious security concern in fragile states. The failure of state institutions to equitably manage natural resources exacerbates the crisis. Therefore, a long-term, multi-sectoral policy response is urgently needed. Integrating climate resilience into international security strategies is essential to protect basic human rights.
