Abstract

Life insurance is an agreement made by the insurance company as the party responsible for providing the guarantee in the form of providing money as risk compensation if an event occurs, such as the death of an insurance participant. As compensation, the insurance participant has the obligation to pay a certain amount of premium to the insurance company. Single premium is a premium payment method that is made once at the beginning. Single premium is a way of paying insurance premiums that are paid all at once at the beginning. Sum Insured is funds that will be given the insurance company to the heirs as a replacement if the insurance participant dies. The purpose of this research is to determine the premium value and compare the premium value if various sums insured are given. And it was found that the greater the sum insured, the greater the premium value that must be paid, and the older a person is when taking out life insurance, the greater the premium value that must be paid.

Abstract

The Indonesian capital market is experiencing significant growth, encouraging investors to consider shares as the main investment option. Fundamental analysis is important in assessing company performance, especially in the property and real estate sectors which are important for the Indonesian economy. This research aims to analyze the influence of fundamental factors such as Return On Assets (ROA), Return On Equity (ROE), Debt to Equity Ratio (DER), and Book Value (BV) on the share prices of property and real estate companies listed on the Indonesia Stock Exchange (BEI) for the 2021-2023 period. Using a panel data regression model with a random effects approach, the results show that BV has a partially significant positive effect on stock prices, while ROA, ROE and DER have a partially significant negative effect. These findings provide insight for investors in identifying key factors that influence share prices, so that they can help in making better investment decisions in the property and real estate sector.

Abstract

This study aims to analyze the influence of soil contour types and depths on soil characteristics using a Randomized Block Design (RBD) method. The research data were obtained from a secondary dataset encompassing physical and chemical soil characteristics across three contour types (Top, Slope, and Depression) and four depth levels (0-10 cm, 10-30 cm, 30-60 cm, and 60-90 cm). The analysis results indicate that soil contour types and depths do not significantly affect most soil characteristics, such as pH, nitrogen content, phosphorus, calcium, sodium, and soil conductivity. However, significant effects were observed on magnesium (Mg) and potassium (K) content. Conversely, area grouping showed significant effects on nearly all tested soil characteristics. These findings highlight the importance of considering geographical variations in soil management to enhance the efficiency and sustainability of agricultural practices. Further research is recommended to explore other factors affecting soil characteristics, such as climate and vegetation types, to support more optimal land management strategies.
