The development of modern society in the process of globalization and industrialization has had a huge impact on forest sustainability as a support for life and in the world's biological life. The existence of forests is of course very much needed considering that forests are not only a source of wood production but are also an integral part of the environment, forests are open areas that make people's access to use them very large which causes logging and timber theft. In order for this to happen more often, this problem must be addressed immediately for the sake of the preservation of forest ecosystems in Indonesia. This journal writing uses normative research methods, normative methods are used with a statutory approach and use reference materials from book sources or other scientific research. As for the results of this study, the regulation of illegal logging is contained in the Law of the Republic of Indonesia Number 41 of 1999 concerning Forestry in Article 50 which regulates prohibitions for anyone who carries out activities in the form of logging, Article 50 also discusses the prohibition of carrying out forest destruction activities. and confiscation of forest resources in violation of laws and regulations or without permission from interested parties, namely forestry officials.

Cassava is a potential food ingredient that has quite good prospects in the fields of agribusiness and agroindustry. Cassava crackers are made from cassava which is processed into crackers, as well as being another alternative food that contains nutritional value. Based on data from the Ministry of Agriculture, Forestry and Fisheries of Timor-Leste in 2009-2010, cassava production reached 47,845 tons. However, cassava production has not been utilized optimally by the people of Timor-Leste as a food ingredient for the nutritional value food industry. therefore, it needs to be developed. The aim of this research is to determine the effect of adding soybean concentration to each treatment and to find out which treatment is best for each parameter used in the test. The method used in this research was a Completely Randomized Design (RAL) with 4 treatments, namely 0% soybean concentration compared to 1 kg of cassava, 10% compared to 1 kg of cassava, 20% compared to 1 kg of cassava, 30% compared to 1 kg of cassava. Each treatment was repeated 3 times. The resulting data will be analyzed using analysis of variance and if necessary, will be presented with a follow-up test of the least significant difference (BNT) at the 5% level.The results of the variance statistical test show that the addition of soybean concentration has a significant effect on the color, taste, aroma and texture of making cassava crackers. This research shows that the best results are 10% soybean concentration in color, taste, aroma and texture.

The occurrence of scorch during the production of flexible polyurethane is a significant issue that negatively impacts foam products' resilience and generally jeopardizes their integrity. The likelihood of foam product failure can be decreased by optimizing production variables based on machine learning algorithms used to predict the occurrence of scorch. Investigating technology is required because prevention is the best approach to dealing with this problem. Hence, machine learning algorithms were trained to predict the occurrence of scorch using the thermodynamic profile of polyurethane foam, which is made up of recorded production variables. A variety of heuristics algorithms were trained and assessed for how well they performed, namely XGBoost, Decision trees, Random Forest, K-nearest neighbors, Naive Bayes, Support Vector Machines, and Logistic Regression. The XGboost ensemble was found to perform best. It outperformed others with an accuracy of 98.3% (i.e., 0.983), followed by logistic regression, decision tree, random forest, K-nearest neighbors, and naïve Bayes, yielding a training accuracy of 88.1%, 66.7%, 84.2%, 87.5%, and 67.5% respectively. The XGBoost was finally used, yielding 2-distinct cases of non(occurrence) of scorch. Ensemble demonstrates that it is quite capable and is an effective way to predict the occurrence of scorch.

Rice plays a vital role as the main food source for almost half of the global population, contributing more than 21% of the total calories humans need. Production predictions are important for determining import-export policies. This research proposes the XGBoost method to predict rice harvests globally using FAO and World Bank datasets. Feature analysis, removal of duplicate data, and parameter tuning were carried out to support the performance of the XGBoost method. The results showed excellent performance based on which reached 0.99. Evaluation of model performance using metrics such as MSE, and MAE measured by k-fold validation show that XGBoost has a high ability to predict crop yields accurately compared to other regression methods such as Random Forest (RF), Gradient Boost (GB), Bagging Regressor (BR) and K-Nearest Neighbor (KNN). Apart from that, an ablation study was also carried out by comparing the performance of each model with various features and state-of-the-art. The results prove the superiority of the proposed XGBoost method. Where results are consistent, and performance is better, this model can effectively support agricultural sustainability, especially rice production.

Tourism is a sector that can be considered profitable and also has the potential for an area to be developed into an asset that is used as a source of production for the region or the country itself. South Solok Regency is one of the regencies in West Sumatra Province, which is one of the prima donna of tourism in this province. Solok Selatan Regency itself is given a quite unique tagline, namely The Heart of Minangkabau. Giving the tagline really represents what the district has. Starting from a variety of tourist and cultural destinations in it. But there are not a few tours in South Solok Regency that have not been exposed by the Tourism Office, one of which is the Tangsi 3 Waterfall Tour. Tangsi 3 Waterfall is located in a tropical rain forest area which has a natural charm that is still beautiful. This waterfall is one of the hidden paradises that this district has.

Forests have a production function, namely economic value, such as wood, rattan, agarwood and so on. Forests have an ecological function because forests are very important for the survival of human beings, animals and plants. Ecological functions include absorbing carbon dioxide and then producing oxygen for life, a source of water, preventing erosion and flooding, habitat for animals, and a source of biodiversity. The purpose of planting tree seedlings is a form of making a production forest where it retains water during floods, secondly as an increase in the economy of the people of Balaroa Pewunu Village. The author uses a descriptive observational method using a persuasive approach to the community by interviews and field observations. By planting candlenut, avocado, jackfruit and petai trees. Implementation of tree seed planting activities on holidays, namely Sundays and trees planted around the river area, with the involvement of village government officials and Risma youth. The planting was carried out in stages considering that there were 850 trees planted including: 500 candlenut seeds, 200 avocado seeds, 100 jackfruit seeds, and 50 petai seeds. The target achieved in planting tree seedlings is expected to become community income in the future. From the community service activities it was concluded that the land in the production forest was used by the community for gardening and farming, then utilizing forest products. The types of forest products that are widely used are candlenut, tamarind, jackfruit, guava, and pineapple.

The research aims to find out how the palm oil mill workforce and how the production of oil palm smallholders contributes to the income of employees who work in oil palm plantations. The Rokan Hilir method used is interviews and documentation. Sampling was done purposively. The productivity of the palm oil mills is very high because the oil palm farmers are always pressing their superiors to achieve the targets they achieve. Meanwhile, oil palm farmers who have to reach the target of factory employees are unable to calculate how much % of their income is very large, so that the used palm fruit piles up in the factory until they have to fertilize the used palm fruit which is commonly called by the local community as janjangan. The saplings are thrown into the forest or into the oil palm, which the smallholders haven't harvested yet, why throw it back into the oil palm because the saplings can fertilize other palm oil. The research was conducted 3 times to interview employees of the palm oil mill. the pressure of oil palm farmers to achieve the target because their income is already optimal.
