Good financial management has a central role in business, involving managing funds effectively and efficiently to maximize profits and company value by managing financial risks. Profitability ratios, especially Return on Equity (ROA), are the main indicators in measuring a company's ability to generate profits. Optimizing operational costs is a key strategy in increasing profitability. This research focuses on PT MSAL, an oil palm plantation company that is trying to increase profitability through optimizing operational costs. A quantitative approach with simple linear regression analysis was used as the research method. Secondary data in the form of financial reports for the last three years (2020-2022) as research objects. The results of the analysis between operational costs and company profitability prove that there is a positive and significant influence. The partial hypothesis test shows that operational costs have a statistically significant impact on profitability. Simple linear regression analysis produces a regression line equation, and the coefficient of determination shows that operational costs have a contribution of 99.4% to the company's profitability. Operational costs have an important role in determining PT MSAL's level of profitability. Optimizing operational costs can improve a company's financial performance. Therefore, companies are advised to continue to evaluate, develop efficient business strategies, and regularly monitor the relationship between operational costs and profitability.

Transportation of oil palm Fresh Fruit Bunches (FFB) from the plantation to the harvest collection point (HCP) must be done as quickly as possible. This is due to an increase in free fatty acids after the FFB is harvested. Some of the obstacles found were the FFB transportation equipment which was not yet capable of reaching the fruit in the garden easily and the transportation time which was quite long due to the uneven road conditions. With technological advances and the rapid development of innovation, the discovery of track model wheelbarrows that use a driving engine means that further studies are needed to determine the effectiveness of these transport machines. In this research, we will compare wheelbarrows without engines and wheelbarrows with track models, there are 3 (three) treatments given, namely on flat roads, bumpy roads and damaged roads. Researchers search for and collect data on transport capacity, transport load, transport speed and transport costs. The results of this research show that carrying capacity and road conditions have a effect on travel time and speed. This is due to the ability/power of the machine which is quite large and stable in transporting fruit. and, other results from this research show that the use of motorized wheelbarrows can reduce transportation costs because the transportation speed increases so that the travel time is shorter.

Soil pH value either with KCl solution or with H2O are two important indicators needed to describe soil acidity. This study aims to determine the distribution of soil pH values in smallholder rubber plantations with different land topography classes in Pelepat Ilir Subdistrict, Bungo Regency, Jambi Province. The study used a survey method with a toposequence concept approach at a semi-detailed level, where observation points were made based on the upper tread polypedon, middle tread polypedon, and lower tread polypedon at each level of percent slope 15-24%, 8-15%, and 3-8%, and flat tread polypedon at a percent slope of 0-3%. Ten composite soils were taken from a mixture of 3 individual soil samples at each polypedon using a soil drill at a depth of 0-30 cm from the soil surface. Soil pH value analysis was conducted in the laboratory on each composite. The results showed that the pH value of the soil with 1:2 H2O solution was very acidic, and acidic for 1:2.5 KCl solution. The distribution of soil pH values showed that the lower slope had a higher pH value than the middle slope, and the upper slope had the lowest pH. Soil pH values decreased as the slope increased, and soils with flat topography were considered more fertile than those with high slopes. This result can be a recommendation in determining liming and fertilization doses, where higher doses are required for high slope soils than flat soils for optimum agricultural yields.

Economics is an interesting field of study if studied from a historical perspective, in its journey, Malang apparently is not only the center of coffee plantations. Malang at that time had a large sugar factory (PG). As the economy of Malang City grew, the number of sugar factories continued to increase. This transformation extends to the trade and service sector which has brought Malang to play an important role as one of the pillars of the economy in East Java. In this research, the author used a qualitative method. The key to the successful evolution of the Malang region's economy is the synergy of political authority (government), the central bank as the monetary authority (BI Malang), and business actors so that they can become a transformative collective force in developing programs with an insight into regional potential and the institutional capacity of the local community, to the ability to adapt and capture new opportunities that arise in a rapidly changing economic order and environment is developed.

Agriculture plays an important role in food sustainability and security in Indonesia, including in the City of Tuban. The city has wide potential for the development of the agricultural sector, including crops, plantations, animal husbandry, forestry and fisheries. However, the limited information regarding the current situation of these sectors raises the need for in-depth analysis. This study aims to analyze the portrait of agriculture in the city of Malang with a focus on crops, plantations, animal husbandry, forestry, and fisheries. This analysis will provide insight into the current status, development potential, challenges and opportunities within these sectors. This research uses a qualitative approach by conducting field surveys, interviews with farmers, ranchers, fishermen, and other relevant stakeholders. The collected qualitative data were analyzed thematically to describe an overall picture of each agricultural sector. The results of the analysis show that the secondary crops sector has experienced positive growth, but still faces challenges in terms of access to markets and technology. Plantations have great potential in the development of superior commodities, but need to improve infrastructure and environmental sustainability. Livestock is experiencing rapid development, but faces problems in waste management and animal health. Forestry is faced with land expansion and forest restoration, while fisheries require steps to maintain the sustainability of fish resources. These findings provide important input for the local government and related stakeholders to develop a strategy for sustainable agricultural development in the City of Tuban. Efforts are needed to improve market access, strengthen infrastructure, improve waste management, improve animal health, and maintain the sustainability of fish resources. This analysis can also be the basis for further research and more effective policy planning in the agricultural sector in Tuban City.
