Abstract

Investment is an activity carried out by investors by placing their funds in an asset. The purpose of investment is to gain long-term profits in the future. These profits come from changes in the price of assets in the future, which refers to the increase in the value of an asset over time. Currently, there are several types of investments. However, the type of investment that is quite widely practiced by Indonesian society is stock investment. The Indonesia Stock Exchange (IDX) groups the stocks available in the stock market into several indexes. One index that is currently receiving attention from Indonesian society is the Jakarta Islamic Index (JII). The JII is a collection of shares from companies that adhere to sharia principles in their business operations. Investment activities must be carried out carefully by conducting analysis beforehand so that investors do not make mistakes in choosing the stocks to be purchased. Several popular methods for selecting stocks are the Sharpe, Treynor, and Jensen indexes. These three indexes can be used to select the best stocks based on their respective criteria. This study combine these three indexes to prioritize the formation of a portfolio. The data used in this study is the closing value of stock prices in the JII index from March 2018 to February 2023. The optimization resulted in a composition of 69.17% for MDKA shares, 26.55% for HRUM shares, and 4.28% for BRIS shares of the total portfolio composition.

Abstract

The abundance of waste cooking oil resulting from the cooking process has not yet been optimized for use. Apart from that, coffee is also produced in Mukai Pintu village, Kerinci Regency. The skin of these coffee beans is just waste that is thrown away. These two ingredients can be used to make aromatherapy candles which are useful for the community. In this way, the problem of waste coffee bean shells and used cooking oil can be overcome and become added value. Making aromatherapy candles from used cooking oil can be made easily by PKK women and the Mukai Pintu Kerinci village community. Coffee skin therapy aroma candles can support the economy of the community and village.

Abstract

This community service aims to increase young women's knowledge and form a cadre of reproductively healthy teenagers. The method for implementing this service was counseling and FGD. The evaluation instrument used the adolescent menstrual attitude questionnaire, which was analyzed descriptively. The results of this service showed that there had been significant changes in young women's knowledge regarding reproductive health and attitudes towards maintaining reproductive health during menstruation and the environment. This result was proven by pretest-posttest data on the knowledge and attitudes of young women in maintaining personal and environmental hygiene during menstruation. Apart from that, reproductive health cadres had been formed to support school activities and personal hygiene for young women. These cadres were volunteers and provided their peers with information related to reproductive health to their peers.

Abstract

A morbidity table is an important mathematical tool in health sciences and actuarial studies, providing an overview of disease rates in a population at a given time. This table offers information on the number of disease cases by age group, type of disease, or geographical region. The values from morbidity tables are used to compare disease rates between populations, evaluate the effectiveness of health programs, and predict future healthcare service needs. In the world of health insurance, morbidity tables play a crucial role in premium pricing calculations. By using specific morbidity tables, insurance providers can set premium prices that align with the conditions of the population being covered, preventing company losses due to premiums being set too low, while also ensuring that people do not feel burdened by excessively high premiums. Despite their importance, creating morbidity tables requires extensive research and large amounts of data. In Indonesia, accurately constructing morbidity tables is challenging due to its vast geographical diversity. Therefore, this study will use the prevalence rate of chronic diseases as an alternative. Prevalence rate is a statistical measure that describes the proportion of individuals in a population suffering from a specific disease at a given time. This approach simplifies data collection, especially since the government regularly releases prevalence data for certain diseases.

Abstract

Produk Domestik Regional Bruto (PDRB) merupakan salah satu indikator penting dalam melihat perkembangan ekonomi suatu daerah. Nilai PDRB Kota Jambi menunjukkan tren meningkat dari tahun 2010 hingga 2024, meskipun pada tahun 2020 sempat mengalami penurunan akibat pandemi Covid-19. Perubahan nilai PDRB dari tahun ke tahun memerlukan peramalan untuk membantu pemerintah dalam mengantisipasi dinamika ekonomi serta mendukung perencanaan pembangunan daerah secara berkelanjutan. Penelitian ini menggunakan metode Double Exponential Smoothing (DES) Holt karena metode ini sesuai untuk data deret waktu yang memiliki pola tren dan mampu memberikan hasil peramalan yang lebih stabil. Penentuan parameter dilakukan melalui proses trial and error menggunakan bantuan solver pada Ms. Excel sehingga diperoleh parameter optimal α = 0,99 dan β = 0,01. Berdasarkan parameter optimal tersebut, peramalan PDRB atas dasar harga konstan menurut lapangan usaha di Kota Jambi untuk lima periode berikutnya menunjukkan peningkatan nilai secara konsisten, yaitu tahun 2025 sebesar 23.753,92; tahun 2026 sebesar 24.613,76; tahun 2027 sebesar 25.473,59; tahun 2028 sebesar 26.333,42; dan tahun 2029 sebesar 27.193,25. Nilai MAPE sebesar 1,5133% menunjukkan bahwa metode DES Holt memiliki tingkat akurasi yang sangat baik. Hasil ini menegaskan bahwa metode DES dari Holt efektif dalam memprediksi perkembangan PDRB Kota Jambi serta dapat dijadikan dasar dalam evaluasi kinerja perekonomian dan penyusunan perencanaan pembangunan daerah pada periode mendatang.
