Abstract

Quantitative population growth but does not compensates with the quality will be a problem. One of the efforts to reduce the population growth rate is the age of first marriage. Based on BPS data in 2017, early marriage in Indonesia is 25.71 percent, meaning that in every 100 marriages, there are 25 couples less than 18 years. This study aims to study the factors affecting the age of first marriage (UKP) in Indonesia. The data used were the results of the 2017 RPJMN Survey with a sample of 51,493 people. The data was taken by systematic random sampling, then the unit of analysis was taken FAW (15-49 years) married as many as 40,268 respondents. The variables studied included residence, wealth quintile, education level, employment status, and age at first marriage. The analysis was performed using descriptive and inferential methods using binary logistic regression models. The results showed 21,405 (53.2%) women at first marriage were more than 20 years old. Meanwhile, those under 20 years of age totaled 18,863 people (46.8%). Statistically, there is a significant relationship between the variables of age at first marriage and residence, wealth quintile, education level, and employment status. Women aged 15-49 years tend to marry or have a high risk of experiencing the age of first marriage over 20 years are those who live in urban areas, high economic status, highly educated, and working.

Abstract

Although the fertility rate in East Nusa Tenggara Province has decreased over the last 10 years, the birth rate is still higher than other provinces in Indonesia. Interestingly, the infertility index for breastfeeding in East Nusa Tenggara Province is the lowest compared to other provinces in Indonesia, which means that women of childbearing age in East Nusa Tenggara Province breastfeed their children with the longest breastfeeding period. Therefore, this study aims to determine the fertility decomposition and characteristics of breastfeeding mothers in East Nusa Tenggara Province in 2017. The data source of this study uses the results of the 2017 Indonesian Demographic and Health Survey (IDHS) using women of childbearing age who have given birth. The analysis used in this study included fertility decomposition analysis and continued with univariable, bivariable, logistic regression analysis. The results of this study indicate that breastfeeding as a proxy for infertility towards fertility in the province of East Nusa Tenggara has an index value (Ci) of 0.72 and after controlling for maternal characteristics variables, age, education and work status of mothers are the factors most related to breastfeeding behavior in East Nusa Tenggara in 2017. Promotion of good breastfeeding techniques and the benefits of breastfeeding needs to be improved in order to improve the quality of life of infants, spacing pregnancies and reduce the incidence of tengkes (stunting).

Abstract

Aplikasi konsentrasi PGPR dan aplikasi pupuk kotoran kambing merupakan salah satu langkah yang digunakan dalam intensifikasi. Hal tersebut karena PGPR mengandung beberapa mikroorganisme yang dapat berperan sebagai pemacu pertumbuhan dan mampu meningkatkan hasil produksi pertanian. Sementara itu, pupuk kotoran kambing dapat menambah unsur hara pada lahan sub-optimal yang cenderung kandungan bahan organiknya rendah, ketersediaan air rendah, keasaman tanah tinggi (pH rendah), dan sangat minim unsur hara. Penelitian dilaksanakan pada bulan Juni - September 2019 di lahan yang terletak di Donowari, karang ploso. Penelitian ini ialah penelitian faktorial dengan menggunakan rancangan acak kelompok, faktor pertama adalah R0: Tanpa PGPR, R1: PGPR 15 ml L-1, R2: PGPR 30 ml L-1. Faktor kedua adalah pupuk organik kotoran kambing, yaitu: P1: 0 ton ha-1, P2: 10 ton ha-1, P3: 20 ton ha-1, P4: 30 ton ha-1. Pengamatan yang dilakukan meliputi komponen pertumbuhan yaitu tinggi tanaman dan jumlah daun. Sedangkan parameter pengamatan komponen hasil meliputi jumlah buah pertanaman, bobot buah pertanaman, diameter buah dan bobot buah pertanaman. Data hasil pengamatan dianalisis dengan menggunakan uji F untuk mengetahui adanya pengaruh dari perlakuan dan dilanjutkan dengan uji antar perlakuan dengan menggunakan BNJ pada taraf kepercayaan 5%. Hasil penelitian menunjukkan bahwa terdapat interaksi antara konsentrasi PGPR dan dosis pupuk kotoran kambing terhadap komponen pertumbuhan dan hasil tanaman terung. Aplikasian PGPR dengan konsentrasi 30 ml L-1 dan pupuk kotoran kambing dengan dosis 30 ton ha-1 mampu meningkatkan pertumbuhan diantaranya tinggi, jumlah daun, persentase fruit set, jumlah buah pertanaman, bobot buah pertanaman, panjang buah dan diameter buah pertanaman.

Abstract

Ensuring quality health coverage for all, especially for older people, is one of the SDGs goals to be achieved. Goal 3 with target 3.8 on universal health coverage (UHC), emphasizes the importance of all people having access to quality health services without the risk of financial hardship. This study aimed to determine the coverage of the National Health Insurance (NHI) and factors related to the ownership of NHI among elderly people in Indonesia. Data from the 2020 National Socio-Economic Survey was used to analyze 121,961 elderly people aged 60 years and above across all provinces in Indonesia. The variables studied included socio-demographic variables, economic status, and health status of the elderly. A chi-square test and binary logistic regression analysis was used to determine the relationship between NHI ownership status and the independent variables. The results showed that most of the elderly were aged 60-69 years, had low education, and lived in rural areas. NHI coverage for the elderly in Indonesia is already good, although there are still high disparities in some regions. The result of logistic regression analysis showed that the NHI ownership status of the elderly has a significant relationship with age, place of residence, education level, and wealth status. Efforts to expand the reach of NHI for the elderly should be increased as one of the strategies in realizing the SDGs targets.

Abstract

Disaster health education is included in disaster mitigation which aims to increase public knowledge and minimize casualties caused when a disaster occurs. School-aged children are a vulnerable group who are still unfamiliar with disaster knowledge, so there is a need for health education about disasters. The aim of the research is to determine the influence of health education on students' knowledge of drought disaster mitigation. This research uses a Pre-Experimental research type that uses a One-Group Pre-Test and Post-Test Design, and uses a total sampling technique with a sample size of 46 respondents. The results of the research before being given health education showed that 29 (63.0%) respondents were at a good level of knowledge with an average score of 10.17. The research results after being given health education increased students' knowledge level, namely 41 (89.1%) respondents had good knowledge with an average score of 11.93. The data analysis used was the Wilcoxon test, with a significance level of a=0.05, the result was r 0.000<a so that H0 was rejected and Ha was accepted. From these results it can be concluded that there is an influence of health education on students' knowledge of drought disaster mitigation.

Abstract

A sustainable economic approach involves achieving economic growth while preserving the environment. One solution aligned with green economy initiatives is the Solar Power Plant (PLTS), which utilizes sunlight as the primary energy source to generate electricity. In response to increasing energy demand and growing environmental concerns, a spare parts supply company in Karawang, West Java, has decided to adopt hybrid energy by investing in renewable energy sources through the installation of an on-grid Solar Power Plant (PLTS) on the factory roof. This study aims to evaluate the financial feasibility of this green economic initiative. The analysis considers various aspects, including initial investment costs, operational and maintenance expenses for key components (solar modules and inverters), potential savings in electricity costs, and the projected return on investment over a specific period. The financial analysis methods applied include Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (DPP), and Profitability Index (PI) to determine the project's economic viability. The findings indicate that the DPP is 2.43 years (well below the 25-year lifespan), NPV is Rp 1,433,144,387.92 (positive and greater than 1), IRR is 46.31% (exceeding the 5.75% benchmark), and PI is 1.95 (greater than 1). Based on these results, it can be concluded that the construction of a rooftop solar power plant with an on-grid system is a financially viable investment for the spare parts supply company in Karawang, West Java.
