Plantation land expansion in forest areas has been a problem for some time as an effort to meet rising food demands, so land suitability measures are required. The development of the Analythical Hierarchy Process (AHP) and Geographic Information System (GIS) combination has been found to be effective in determining land suitability, but still rarely to determining plantation crops in forest areas. The study's goal was to integrate AHP and GIS methods to evaluate the land suitability class for plantation crops in the Wonosalam forest area. The findings revealed that the land suitability class assessment obtained S3 results, or results that were slightly in accordance with the erosion hazard constraint, to potentially S2 results, or results that were quite in accordance with many constraints such as retention factors, nutrients, erosion hazard, and land preparation. Furthermore, the expert decision-making hierarchy concluded that topography, climate, soil physical properties, and nutrient retention can consistently influence the direction of land suitability assessment policies for durian, clove, and coffee species. Rainfall, altitude, land preparation, and c-organic content are all important priority parameters in determining land suitability for durian plants. In contrast to cloves, temperature, surface rock, erosion, and pH are known to be important factors in determining land suitability. Experts also consider humidity, altitude, land preparation, and C-Organic as a land suitability assessment for the different types of coffee plants in the Wonosalam Forest Area.

“…Ultimately, it hopes to help the government make better choices [8,9]. According to studies [10,11], everyone has a chance to weigh in on municipal planning decisions [12]. On the other hand, local governments often ask residents and other members of civil society with whom they have already collaborated for their thoughts.…”

Regional planning is a method of development planning that leverages present resources to better a public community, government, and environment in a specific area. It is essential to gather and assess regional planning research from across the globe in order to provide informed suggestions for domestic regional planning and the implementation of suitable laws. Studies on regional planning are particularly significant when given as bibliometric analyses. The purpose of this research is to discover distinct research trends in bibliometrics relevant to the topic of regional planning. Using statistics, we examine the number of articles on regional planning that have been published in the recent five years in this study. Alois Humer, who works at the University of Vienna in Austria, has a high level of scientific production as well as recognition in this subject. Researchers studying regional planning utilize the total number of papers published in each publication to classify journals into separate regions. According to Bradford's rule of document transmission, the IOP Conference Series Earth and Environmental Science is the most significant journal on this subject. Looking at the numbers, it is also clear that China has published a total of 145 articles throughout the past five years. The word "regional planning" appears 126 times in the title, which is rather remarkable. This phrase is related to the article's keywords' theme. This image incorporates the terms "China," "Indonesia," "Germany," and "Nigeria," implying that the bulk of research on "regional planning" themes is conducted in these four nations.

“…Simulation compared the performance of many LVQ classifiers in the application of the strategies indicated above using a large computer. This suggests that the proposed methodology leads to a high level of classification in the end [19], [20]. Based on related studies and the problems that have been raised, this study proposes the use of the LVQ algorithm to classify electricity users at PT.…”

Electricity is vital energy for the sustainability of human activities both as individuals, community groups, and the industrial world. Electricity users are increasing every year, which causes irresponsible users and does not comply with existing rules; the number of users causes the staff to find it challenging to determine whether the power used is appropriate with household needs. This study uses data on 100 electricity users obtained from PT. PLN Rayon Trade is one of the branch offices of PLN in Indonesia. The method used to classify electricity users is the Learning Vector Quantization (LVQ) algorithm using the 4-8-3 architectural model. Several input variables are used, such as the number of bills, the number of hours, the metered rate, and the class. The results obtained an accuracy rate of 72% with a time of 11 minutes 53 seconds. So it can be concluded that the LVQ algorithm with the 4-8-3 architectural model can be used to classify electricity users. However, it is not very good because the accuracy still needs to be improved.
