Oil palm (Elaeis guineensis Jacq.) is one of the world's important commodities as a producer of vegetable oil needed by various industries. Leaf area index is one of the indicators of plant growth seen from the size of the leaf surface area that carries out the photosynthesis process. This study aims to determine the interaction of NPK Phonska fertilizer dose treatment and its application method on the Leaf Area Index of oil palm seedlings at the pre-nursery stage. The study was designed using factorial RAK consisting of 2 factors, namely the dose of NPK Phonska fertilizer (K) and its application method (A), and 3 replications. The K factor consists of 5 levels, namely K0 = 0 g/seedling; K1 = 0.5 g/seedling, K2 = 1 g/seedling, K3 = 1.5 g/seedling, and K4 = 2 g/seedling. Factor A consists of 3 levels, namely A1 = watering, A2 = spreading, and A3 = bag. The observation results were analyzed using analysis of variance and further DMRT test at 5% level if significantly different. The results of the study showed that the dose of NPK Phonska fertilizer 1 g/seedling (K2) gave the highest results on the Leaf Area Index, which was 2.90. The interaction treatment of NPK Phonska fertilizer dose 1 g/seedling and the pocket application method (K2A3) gave the highest results on the parameters of seedling height (12.99 cm) and tuber diameter (1.31 cm). The Leaf Area Index weakened positively on the growth of oil palm seedlings as seen from the height of the seedlings, tuber diameter, and leaf sheath length.

The background of this study stems from a number of issues, including the inability of oil palm farmers to make ends meet financially, the impact of their reliance on oil palm income on the well-being of their families, and the relationship between oil palm farmers' income and the price at which Palm Fruit Bunches (FFB) are sold in Nagari Bawan, Kabupaten Agam. Nonetheless, a lot of farmers continue to struggle with a shortage of funding when it comes to running oil palm plantations and boosting the output of palm fruit bunches (FFB). A qualitative descriptive research approach is used, and it involves gathering research objects based on field data. Direct observation and interviews with oil palm farmers in Nagari Bawan, Kabupaten Agam, were used to gather data. The Nagari Bawan administration (Nagari Secretariat) and thirteen oil palm plantation owners were the research's primary sources of information about the circumstances and state of the study in Nagari Bawan, Kabupaten Agam. According to the author's study findings in Nagari Bawan, Kabupaten Agam, income indicators such as monthly income, employment, and family responsibilities may be used to analyze oil palm farmers' income in order to improve the economic welfare of their families. This indicates that oil palm growers are looking for side employment since their revenue is insufficient to cover their expenses.

The development of the automotive world to date has grown rapidly, especially two-wheeled vehicles. Large temperature changes in lubricating oil viscosity, even if the value is too low, will reduce the lubrication of engine parts, increase friction between metals, and cause engine parts to heat up quickly.

The Indonesian government is enthusiastic about continuing the biodiesel program as one of the new and renewable energy mandatory programs which has proven to be able to provide many benefits ranging from achieving environmentally friendly energy, saving state foreign exchange, increasing energy security, to providing jobs; in line with the 7th principle of sustainable development goals (SDGs). In fact, the Indonesian government has increased the B30 Biodiesel program in 2020 to B35 in 2023. It is supported by the Palm Oil Plantation Fund Management Agency (BPDPKS), which has the authority to collect CPO export levy funds and redistribute them to biodiesel producers, so that they can produce biodiesel economically. With this mechanism, the Biodiesel program can be implemented even though the price of biodiesel is more expensive than fossil fuels, but does not burden the State Budget (APBN). However, this program is difficult to increase, because the availability of incentive funds is limited by the amount of CPO exported and the amount of the levy. The Ministry of Energy and Mineral Resources (ESDM) must find a way for the biodiesel energy program to achieve the 23% energy mix target in 2045, and not rely on export fund levies anymore.

Land classification for oil palm plantations is an important topic in agricultural and plantation development. In this research, the local binary pattern (LBP) method and support vector machine (SVM) classification were used to identify oil palm plantations from aerial photography images. The main challenge in this process is accurately distinguishing oil palm fields and forests that have similar patterns and colors in satellite images. The LBP method is used to extract important texture features from images, while SVM is used to build a classification model based on these features. The test results show that using this method provides an accuracy value of 83.33% in the classification of oil palm land images. The development of oil palm plantations in Indonesia is becoming increasingly important as investment prospects strengthen. This research helps develop image classification technology to support the agricultural industry.
