Nipah Panjang Village in Kubu Raya Regency, Indonesia, has diverse mangrove forest vegetation. Meanwhile, the mangrove forest in Nipah Panjang Village has the potential threat of deforestation, so it is necessary to develop a management strategy. A mangrove management directive can be compiled with mangrove biophysical data and the social conditions of the surrounding community. Therefore, this study aims to examine the distribution of mangrove forest areas and their utilization by the community in Nipah Panjang Village. The method used in this study was GIS analysis to determine the distribution of mangrove forest areas. In this study, observations and interviews were carried out to determine the use of mangrove forests. The study results show that from 2013 through 2018, there was around 3.12 Ha of deforestation. Deforestation that occurred was much lower than the previous year. It was due to the implementation of a devolution policy that granted village forest permits in Nipah Panjang Village. Currently, the forms of utilization of mangrove forests in Nipah Panjang Village are the farming (apiculture)  of kelulut honey, forest honey farming, and crab farming with the concept of silvofishery and the development of ecotourism. This form of utilization needs to be maximized so that the community's welfare increases, ultimately maintaining the mangrove forest.

The purpose of this study is to analyze the neutrality regulation of State Civil Servant (ASN) neutrality in the current regional elections is in effect and how the ideal form of ASN neutrality regulation in the regional elections is viewed from the study of the regional elections Law and other derivative rules as well as the theory of legal objectives. Several regulations, ranging from laws and government law to joint decrees involving several ministries and institutions, were issued in order to limit the space for movement and ensure the neutrality of ASN is maintained in the implementation of regional elections. This research is expected to be able to find the ideal setting regarding ASN Neutrality in regional elections by analyzing several applicable regulations. This study uses a normative juridical approach by using secondary data through the study of legislation and literature searches. This research has a novel perspective, namely trying to find the ideal form of regulation of ASN neutrality in the regional elections in terms of several applicable laws and theories of legal objectives. The results of this study conclude that the neutrality of ASN in the regional elections is regulated by the ASN Law, Regional Elections Law, Government Law Discipline of Civil Servants, Government Law for the Development of Corps Spirit, and Code of Ethics for Civil Servants, Circular Letter of KASN, Circular Letter of Menpan-RB, and Joint Decrees of 5 Ministers/Heads of Institutions. In addition, it is necessary to reposition the ASN neutrality rules under one legal umbrella, namely the KASN Regulations.  Tujuan penelitian ini untuk mengkaji pengaturan netralitas ASN dalam Pilkada yang berlaku saat ini dan bagaimana bentuk ideal pengaturan netralitas ASN dalam Pilkada ditinjau dari kajian pada UU Pilkada dan aturan turunan lainnya serta teori tujuan hukum. Beberapa regulasi mulai dari UU, PP, sampai dengan Keputusan Bersama yang melibatkan beberapa Kementerian/Lembaga diterbitkan dalam rangka membatasi ruang gerak dan menjamin netralitas ASN tetap terjaga dalam penyelenggaraan Pilkada. Penelitian ini diharapkan dapat menemukan pengaturan ideal terkait Netralitas ASN dalam Pilkada dengan menganalisa beberapa regulasi yang berlaku. Penelitian ini menggunakan pendekatan yuridis normatif dengan menggunakan data sekunder melalui studi perundang-undangan dan penelusuran literatur.

The recruitment of new mechanics at Mataram Sakti is no longer through the training process at the head office, but new mechanics are placed at the dealership accompanied by the chief mechanic as a supervisor, with the aim of providing training to new mechanics in order to be able to service or periodically repair Yamaha products especially the latest motorbikes namely Yamaha NMAX, because of the flurry sometimes the mechanical head is not in place so that when the mechanic is experiencing problems it cannot directly ask the mechanical head causing the handling of repairs to be less effective and efficient.
One way to overcome this is to create a web-based expert system application with a forward chaining method so that the chief mechanic can transfer the knowledge he has into the computer. Forward chaining method is a search technique that starts with known facts and then matches these facts with the IF part of the IF-Then rules, so that conclusions can be drawn. This expert system was built using supporting software including, Macromedia Dreamweaver MX, PHP script language, MySQL database and WAMP server.
The expert system for diagnosing damage to Yamaha NMAX motorcycles using the forward chaining method can be used as a new mechanical learning media in diagnosing damage to NMAX motorcycles and as a means of chief mechanics transferring their knowledge.
