Open pit mining is a mining system that is commonly applied to coal extraction activities. Environmental problems in coal mining activities are generally related to acid mine drainage (AMD). Efforts to overcome the impact of AMD can be done by phytoremediation in constructed wetlands (CW). Plants that have the potential for AMD phytoremediation include Pistia stratiotes L (water lettuce) and Salvinia molesta Mitchell (giant Salvinia) , so it is necessary to conduct research on the effectiveness of the combination of P. stratiotes and S. molesta to be developed on CW vegetation. The experimental design used was a completely randomized design (CRD), with 3 treatments using P. Stratiotes, S. Molesta, Combination of P. stratiotes and S. molesta each 9 replications. The results showed the effectiveness of phytoremediation using plant vegetation of P. stratiotes and S. molesta in increasing pH by 40.04% and reducing sulfate levels by 41.72%. The effectiveness of the combination of P. stratiotes and S. molesta in reducing levels of Mn and Fe were 101.36% and 93.49%, respectively. The decrease in TSS levels is better done by the combination of P. stratiotes and S. Molesta vegetation compared to P. stratiotes or S. Molesta vegetation alone, but the better growth rate occurred in S. molesta vegetation only.

The agrarian reform program launched by the government basically aims to improve the welfare of the people, especially landless farmers. Through Presidential Regulation Number 86 of 2018 concerning Agrarian Reform, the government is trying to redistribute land for farmers, including those carried out in Kubu Raya Regency. However, in practice the land redistribution program carried out by the government isn’t in accordance with the procedures stipulated in Presidential Regulation Number 86 of 2018. Of the 10 access arrangement activities as stated in Presidential Regulation Number 86 of 2018, only 2 activities were carried out by Kubu Raya District Land Office. Before carrying out the implementation of land redistribution, the Land Office must first make a plan which is preceded by the preparation of operational instructions. Counseling on land redistribution activities should be carried out at the planning stage. In practice, the Kubu Raya Land Office doesn’t go through established mechanisms or procedures and directly conducts counseling at the implementation stage of activities that should have been carried out at the planning stage. In addition, the Land Office doesn’t control land whose area exceeds the maximum land ownership limit, which the government wants to control through the agrarian reform program.

The land acquisition process requires the involvement of various parties, one of which is the Land Deed Making Officer (PPAT). PPAT has an important role in ensuring the validity of land administration through the creation of authentic deeds, such as deeds of sale and purchase, deeds of gift, and deeds of release of rights. In the context of land acquisition for public interest, the authority and responsibility of PPAT are very crucial in ensuring legal certainty for all parties involved. This study aims to find out and understand the authority of PPAT in the process of land acquisition for public interest and to analyze the legal responsibility of PPAT in making words related to land acquisition. The type of research used in this thesis is normative legal research, namely research that focuses on the study of laws and regulations, legal doctrine, legal principles, and relevant literature. This study is used to analyze the authority and responsibility of PPAT as regulated in the positive legal system in Indonesia, especially in the context of land acquisition for public interest. The results show that the PPAT's authority in land acquisition for public interest is to make authentic deeds related to the transfer of land rights, such as deeds of sale and purchase, deeds of release of rights, and deeds of gift. This authority is administrative in nature and does not include the assessment of compensation or determination of land acquisition policies and the legal responsibilities of the PPAT include ensuring the validity of documents and the identities of the parties, as well as ensuring that the transferred land is not in dispute. PPAT's negligence can have legal consequences, both administrative, civil, and criminal.

This study aims to analyze the forms of default that occur in shop house lease agreements in the commercial area of Samarinda City and to examine the mechanisms for resolving them. The background of this study is based on the fact that the commercial area in Samarinda is growing rapidly, making shop rental practices an important necessity for economic activities. However, on the other hand, these practices are prone to disputes due to the failure of one party to fulfill their obligations. This study uses an empirical method, where data is obtained through interviews and the distribution of questionnaires to 25 respondents (shop owners and tenants), as well as case documentation at the Samarinda District Court. The results of the study show that the most dominant form of default is late payment of rent, experienced by 62% of shop owners, followed by misuse of shop functions at 18%, and unilateral termination of contracts at 12%. In terms of dispute resolution, 70% of cases were resolved non-judicially through deliberation and mediation, while 30% resolved through litigation in court. The study also found that most lease agreements were made without the involvement of a notary or legal advisor, so that the clauses of the agreement tended to be simple and legally weak. Thus, this study concludes that default in shop lease agreements in Samarinda City is a real and recurring problem, but it can still be minimized through stronger agreements, the involvement of notaries, and increased legal awareness among the parties. This study is expected to contribute to the development of civil law, particularly in the practice of lease agreements in commercial areas.
