HARMONIZATION OF LAND REGULATIONS IN THE CAPITAL CITY OF THE ARCHIPELAGO (IKN) WITH NATIONAL REGULATIONS IN THE LAND SECTOR
Full text linkThe construction of the National Capital in Penajam Paser, Kalimantan, has entered 25% of its construction, but it turns out that there are still several problems arising from the construction of this new capital. The infrastructure has been built, and preparations for the capital relocation have been partially implemented. The new capital city is located in Balikpapan Bay, East Kalimantan, and Nusantara. One of the problems with the construction of this national capital is the land issue because some of it is state land, and some is citizen land or customary land. As is known, Penajam Paser is located in a forestry area that also includes coastal areas and mangrove forests, residential areas, and mining. There are 21 indigenous community groups recorded as inhabiting the IKN area. As an inseparable part of the IKN development project, the existence of indigenous communities is problematic. On the one hand, these indigenous communities must be part of the region's development. Socio-historically, they have a long history in their socio-cultural life, passed down from generation to generation. On the other hand, in practice, the existence of indigenous communities was not involved in the initial formulation. The problem arises from land regulations in the IKN, whether they refer to the rules that apply nationally or if there are special rules for the IKN. If there are special rules, how can these rules be harmonized

No full textAcid circulation pumps are the main equipment of the absorption process of SO3 gas into sulfuric acid solution. The acid pump at the Sulfuric Acid Plant is prone to deterioration in performance due to interrelated causative factors. Meanwhile, the replacement of the acid circulation pump can only be done in major maintenance situations (large-scale maintenance, care, and repair actions) so it is important to maintain the condition of the acid circulation pump to operate properly without any problems. This paper discusses important aspects that are factors that cause problems in the operation of the acid circulation pump related to black out and forced shut down, along with suggestions for improvement to prevent the same problems from occurring in the future
Implementasi Kebijakan Revitalisasi Industri Pupuk Nasional
Full text linkFood security is one of the important factors in realizing the targets of the Sustainable Development Goals (SDGs). One of the main aspects of strengthening food security is increasing fertilizer production that supports the agricultural sector. Regarding this, the Indonesian government initiated a fertilizer industry revitalization program based on Presidential Instruction Number 2 of 2010. This program aims to replace old factories with new, more efficient technology, increase production capacity, and reduce dependence on imports. Since the implementation of the fertilizer industry revitalization program, the production capacity of urea and NPK fertilizers has increased significantly. New factories built since 2015 have contributed to meeting national fertilizer needs and increasing efficiency by reducing natural gas consumption. Collaboration between the government, private sector, and the community is critical to the long-term success of the national fertilizer industry. Fertilizer industry revitalization needs to continue to achieve sustainable food security in Indonesia

Hubungan Antara Psychological Hardiness dan Acculturative Stress pada Mahasiswa Indonesia yang Merantau ke Luar Negeri
Full text linkIndonesian students studying abroad often face various challenges during their adaptation process, which can lead to acculturative stress. Psychological hardiness is a key factor that may help reduce this stress. It is a personality trait that enables individuals to cope with stress by viewing challenges as opportunities for growth and maintaining commitment and control in difficult situations. This study aimed to examine the relationship between psychological hardiness and acculturative stress among Indonesian students abroad. A quantitative method with correlational analysis was used, involving 140 Indonesian students who had been studying abroad for no more than two years as of October 2024. Data were collected using the Hardiness Scale and the Acculturative Stress Scale for International Students (ASSIS). The results revealed a negative correlation (-.313) between psychological hardiness and acculturative stress. Specifically, the control (-.358) and challenge (-.321) dimensions of psychological hardiness were also negatively correlated with acculturative stress. These findings suggest that students with higher psychological hardiness perceive themselves as capable of managing their environment and see change as a positive experience, which reduces stress. Future research is recommended to further explore the role of psychological hardiness in reducing acculturative stress among international students
