Climate change is one of the major challenges in the world today, characterized by changes in meteorological values, such as rainfall and temperature, caused by the concentration of greenhouse gases in the atmosphere, such as CO2, N2O, and CH4. These accumulated greenhouse gases form a layer that prevents heat radiation from escaping, causing the greenhouse effect and global warming. Addressing the effects of greenhouse gas emissions requires appropriate strategies, one of which is to predict future greenhouse gas emissions for planning appropriate actions. Time series models such as the Autoregressive Integrated Moving Average (ARIMA) model are often used but have drawbacks due to their assumption of linear relationships. On the other hand, the Long Short-Term Memory (LSTM) model, introduced by Hochreiter and Schmidhuber in 1997, can learn complex and nonlinear relationships in data. This study uses LSTM to estimate greenhouse gas emissions in Indonesia based on emitting sectors, hoping to anticipate negative impacts and reduce greenhouse gas emissions. The results show that the LSTM model has good performance with an error below 20%, and it is predicted that greenhouse gas emissions will continue to increase.

This research aims to assess the soil fertility conditions in a coffee cultivation area in Girsang Sipangan Bolon Village, Simalungun Regency. This evaluation is conducted by examining both physical and chemical soil characteristic at two sampling depths: 0-20 cm and 20-40 cm. Key indicator analyzed include bulk density, water retention capacity, pH levels, and organic matter content. The findings indicate that the soil’ bulk density (ranging from 1.06 to 1.07 g/cm3) is within optimal parameters, moisture retention at field capacity is notably high (44.92% to 47.06%), and the organic matter concentration surpasses the minimum threshold typically required for mineral soils, with values between 4.69% and 5.09%. Soil pH ranged from slightly acidic to neutral, depending on the type of solution applied. In inclusion, the soil in the study area demonstrates a good fertility level to support various types of crops. Of course, this research has many impacts or benefits for coffee farmers, for example in the first case, namely, in terms of optimizing or using land management practices, the results of this research can later be used as a basis for agricultural extension materials that will later be used in the field and of course also have an influence on the steps of farmers in handling the land which will certainly have an impact in the future on the productivity of plantation crops, especially in the area. However, further research is recommended to assess climatic and landform factors in order to determine a more comprehensive land suitability classification.

Violence is a form of action that tends to be physical which causes injury, pain or something that requires attention, namely coercion or unwillingness of the injured party. Violence can be carried out using physical means, resulting in children suffering from injuries from being hit, throwing hard objects, and much more. Psychologically, children will experience the formation of bad attitudes in themselves, namely difficulty focusing, difficulty sleeping, eating disorders, and a tendency to hurt themselves. Some violence against children occurs in the child's own home, school, and in the environment where the child interacts. To prevent violence against children, this can be done by paying attention, supervising and caring for children correctly and diligently. The government needs to make a law about violence against children and punish perpetrators of violence against children to make them aware of what they are doing. The purpose of this research is to illustrate the impact of violence on children and how to prevent it. This research was carried out using normative juridical (normative legal research methods) which was carried out using journals and books.

This study aims to analyze the position and limits of the attribution authority of the Environment and Forestry Service (DLHK) of Bengkulu Province in protecting Rafflesia arnoldii as an endemic flora, and to assess the effectiveness of the implementation of legal protection instruments in addressing the threat of habitat destruction and illegal exploitation. The research method used is normative juridical with a legislative and conceptual approach, supported by limited empirical data through literature study. The results show that DLHK has strong and independent attribution authority based on the Law on Conservation of Biological Natural Resources and the Law on Regional Government, with the scope of regulatory, supervisory, law enforcement, and coordination functions. However, the implementation of legal protection for Rafflesia arnoldii has not been optimal. This is due to the high level of habitat destruction due to human activities, the persistence of illegal exploitation, limited institutional resources, and weak supervision and law enforcement. In addition, low public awareness also exacerbates this condition. Therefore, more comprehensive efforts are needed through strengthening institutional capacity, improving law enforcement, sustainable habitat protection, and community involvement in conservation activities. Thus, it is hoped that protection of Rafflesia arnoldii can be more effective and sustainable.

Accurate evaluation of house valuation is crucial. Misestimation of house prices creates serious consequences for a variety of stakeholders. House prices can be modeled as a function of their constituent attributes. House prices are fuzzy due to negotiation and unpredictable market conditions. This study aims to develop rules to predict triangular fuzzy numbers of price for a given new house by implementing locally weighted KNN-based fuzzy regression, and to compare its performance with possibilistic fuzzy regression. The dataset used is the house valuation dataset. Data is examined using the modified Cheng and Lee k-nearest neighbor fuzzy regression and Tanaka’s possibilistic fuzzy regression. It is found that the modified Cheng and Lee k-nearest neighbor fuzzy regression outperforms possibilistic fuzzy regression in predicting the triangular fuzzy number of the house prices. The best performance is achieved when data is trained using the modified Cheng and Lee k-nearest neighbor fuzzy regression using: = 29 nearest neighbors, Minkowski distance with exponent parameter = 1.6 and an unequal weighting scheme with r = 1.
