Abstract

This study aims to analyze the influence of interest rates and exchange rates on investment in Indonesia. A quantitative research approach was employed, utilizing secondary data in the form of time series obtained from the Central Statistics Agency (BPS) and Bank Indonesia for analysis. The data were processed using multiple linear regression analysis, complemented by classical assumption tests and hypothesis testing. Data analysis was conducted using the Statistical Package for the Social Sciences (SPSS) version 22. The findings of the study reveal that interest rates have a significant negative effect on investment in Indonesia. This indicates that rising interest rates tend to discourage investment, as the cost of capital becomes more expensive, thereby reducing incentives for both domestic and foreign investors. On the other hand, the exchange rate has a significant positive effect on investment, implying that an appreciation of the domestic currency correlates with increased investment levels. A stronger currency may reduce the cost of imported capital goods and materials, thereby supporting investment growth. These results emphasize the critical role of effective monetary policy in regulating interest rates and maintaining exchange rate stability to foster a conducive investment climate. Policymakers are advised to consider the dynamics between macroeconomic indicators and investment flows in designing sustainable economic strategies. Overall, the study contributes to a deeper understanding of macroeconomic determinants influencing investment behavior in developing economies such as Indonesia.

Abstract

Indonesia is among the countries with a high prevalence of stunting. National data indicate that efforts to reduce stunting require cross-sectoral attention, including at the primary service level such as Posyandu. The Indonesian Nutrition Status Survey (SSGI) reported that the stunting prevalence in Cimahi City is 16.4%, with a target to reduce the stunting rate to below 14% by 2024. Stunting is a major public health issue of national concern. This activity aims to enhance the capacity of Posyandu cadres in Cimahi City to support the national efforts in reducing stunting rates. The implementation method includes socialization activities, Self-Awareness Surveys (SMD), Community Consultations at the RW Level (MMRW), implementation, and evaluation. Information dissemination and training are delivered through effective media such as PowerPoint presentations, leaflets, X-banners, and videos. The results of the activity, assessed through pre-tests and post-tests, show an increase in the knowledge of Posyandu cadres, with the average score rising from 60/100 to 80/100, and some cadres even achieving the maximum score. This indicates that the provided materials were well received and understood. The conclusion of this empowerment activity is that there has been an increase in the knowledge capacity of Posyandu cadres regarding their roles and functions in stunting prevention.

Abstract

Nyamuk dapat menyebabkan dampak negatif apabila tidak dikendalikan, salah satunya penyakit yang ditularkan melalui vektor yaitu Demam Berdarah Dengue (DBD). Metode pengendalian nyamuk yang dapat digunakan salah satunya dengan pemasangan perangkap menggunakan atraktan dari fermentasi singkong. Pemasangan perangkap dapat menjadi alternatif karena lebih aman bagi lingkungan dan kesehatan manusia untuk mengendalikan vektor nyamuk Aedes aegypti. Tujuan penelitian ini yaitu untuk mengetahui konsentrasi fermentasi singkong yang paling efektif pada perangkap nyamuk Aedes aegypti. Jenis penelitian ini yaitu True experiment research skala laboratorium dengan metode Post-test Only with Control Design. Penelitian melakukan pengujian terhadap 3 variasi konsentrasi fermentasi perbandingan ragi dan singkong (gr) yaitu 1:50, 2:50, dan 3:50. Kontrol penelitian ini menggunakan perangkap nyamuk berisi akuades (tanpa fermentasi singkong). Sampel penelitian ini adalah nyamuk Aedes aegypti berumur 3 hari dengan teknik sampling purposive sampling. Berdasarkan hasil analisis data menggunakan One Way Anova diketahui bahwa terdapat perbedaan yang signifikan antara variasi konsentrasi fermentasi singkong terhadap nyamuk Aedes aegypti yang terperangkap, hal tersebut dikarenakan Nilai P < α (0,000 < 0,05). Konsentrasi fermentasi singkong yang paling efektif sebagai atraktan pada perangkap nyamuk Aedes aegypti adalah konsentrasi fermentasi singkong 3:50 dengan jumlah 88 ekor (14,67%). Disarankan penggunaan perangkap nyamuk dengan antaraktan konsentrasi fermentasi singkong 3:50.
