Abstract

This paper focuses on the use of enzymes in effective and efficient poultry feed formulations. The introduction highlights the importance of good nutrition for poultry and the increasing need for innovative feed formulations due to limited availability and rising prices of feed ingredients. Enzymes are introduced as protein compounds that enhance nutrient digestion and absorption in poultry, potentially reducing feed production costs. However, their widespread use in Indonesia is still limited due to a lack of knowledge. The paper discusses the role of enzymes in poultry nutrition, including their involvement in digestion and nutrient absorption. It also emphasizes the essential nutrients required for poultry growth and development and the factors influencing their nutritional needs. The types of enzymes commonly used in poultry feed formulations, such as phytase, amylase, protease, and lipase, are explored along with their mechanisms of action. Research findings demonstrate the effectiveness and efficiency of using enzymes in improving nutrient availability and feed efficiency, ultimately enhancing poultry production productivity and sustainability. The paper concludes with recommendations for the development and application of enzymes in poultry feed formulations, highlighting the need for careful enzyme selection, dosage adjustment, and consideration of environmental conditions. Furthermore, the importance of integrating enzymes with other feed ingredients and adopting a comprehensive nutrition strategy is emphasized. Overall, the use of enzymes in poultry feed formulations offers significant advantages for modern poultry farming, but careful implementation and further research are necessary to optimize their effectiveness and efficiency.

Abstract

The education enrollment rate is crucial for Indonesia to improve its human resources and sustain its economic development. In reality, the dropout student rate is still relatively high. Previous research has highlighted several factors and models related to the dropout student rate in Indonesia. The purpose of the study is to identify the most popular statistical modeling and factors influencing school dropout in Indonesia. We searched in February 2023 using ScienceDirect, ProQuest, and Google Scholar. The search was restricted to refereed journal articles published in English from January 2013 to December 2022. This study underwent four stages: identification, screening, eligibility, and inclusion. The study finds that the most popular statistical modeling is the Logistic Regression Model, and the most significant factor increasing the school dropout rate in Indonesia is family and economic factors. The findings suggest that children who were not attending school came from families with lower levels of education. The well-being of these families was directly linked to their children's educational status. The primary reasons for young students dropping out of elementary and junior schools include an inability to pay school fees and a desire to work on farms to support their parents.

Abstract

Tangerang is counted among Indonesia's fastest-growing industries and population since it is located near the capital. At the current rate of population growth, the population by 2035 is expected to reach more than 2 million by appliying the geometric method. Rapid population growth has severe environmental damage. A simple linear regression calculation was applied to predict the Tangerang waste generation and it is expected to grow to 1,57 million tonnes by 2035. The Pearson's correlation was used to examine the impact of population growth in Tangerang on waste generation. Overall, there is a positive correlation between population growth and waste generation. The increase in the amount of waste can affect the formation of leachate. Rawa Kucing is the main Tangerang landfill that implements an open dumping system in its waste management. One of the negative impacts of the open dumping system is the potential for leachate generation. This study performed a simple calculation of leachate volume to illustrate leachate generation in Rawa Kucing. The more leachate produced, the greater the level of contamination since it contains highly toxic components, and it will escape from the Rawa Kucing landfill, contaminating the groundwater, potentially polluting the environment and harming human health.
