Abstract

Acute Respiratory Infection (ARI) in Indonesia generally occurs in urban areas and always ranks first as a cause of death in infants or toddlers. Studies on the incidence of ISPA in toddlers in rural areas are still rarely studied. This study aims to analyze the relationship between nutritional status and exclusive breastfeeding with the incidence of ARI in toddlers. This study was an analytic survey study with a case-control design. The population in this study consisted of 68 toddlers diagnosed with ISPA and all of them were sampled with a ratio of 1:1 and the total sample was 136 people. The toddler's mother pleaded as the respondent. The instruments used were questionnaires and health cards (KMS) for toddlers. Data analysis used is chi square. Statistical analysis of the relationship between nutritional status and the incidence of ARI (P=0.001) and the relationship between exclusive breastfeeding and ARI was obtained (P=0.001). This means that there is a significant relationship between nutritional status and exclusive breastfeeding program and the incidence of ARI. Nutritional status and exclusive breastfeeding programs contribute to the incidence of ARI among toddlers in rural areas. This study recommends that mothers prioritize giving primary food to babies in the form of exclusive breastfeeding for 2 years according to the guidance of the Koran. This action will greatly affect the nutritional status of toddlers, especially in preventing ARI.

Abstract

Pasar modal Indonesia menunjukkan perkembangan yang pesat dengan meningkatnya jumlah investor serta variasi instrumen investasi yang ditawarkan. Kondisi ini menjadikan pengelolaan portofolio sebagai aspek penting dalam strategi investasi modern. Kajian ini bertujuan untuk menelaah penerapan Teori Portofolio Modern (Modern Portfolio Theory/MPT) dalam konteks pasar modal Indonesia melalui pendekatan studi literatur. Teori ini, yang diperkenalkan oleh Harry Markowitz, menekankan pentingnya diversifikasi aset untuk meminimalkan risiko dan memaksimalkan tingkat pengembalian investasi melalui pemben ygtukan portofolio yang efisien. Metode penelitian yang digunakan adalah studi literatur deskriptif-analitis dengan meninjau artikel ilmiah nasional dan internasional yang diterbitkan antara tahun 2022 hingga 2025. Hasil kajian menunjukkan bahwa prinsip diversifikasi dalam kerangka MPT terbukti efektif dalam mengelola risiko portofolio di pasar modal Indonesia. Namun demikian, penerapannya masih menghadapi beberapa kendala seperti keterbatasan likuiditas saham, volatilitas pasar yang tinggi, serta asumsi-asumsi MPT yang tidak sepenuhnya sesuai dengan kondisi pasar domestik. Beberapa penelitian juga mengindikasikan bahwa model Markowitz dan pendekatan indeks tunggal masih menjadi metode utama dalam pembentukan portofolio optimal, meskipun hasilnya sangat bergantung pada kondisi ekonomi dan karakteristik investor. Temuan ini mengungkap adanya kesenjangan penelitian (research gap) terutama dalam integrasi faktor baru seperti prinsip syariah, keberlanjutan (ESG), dan model multifaktor yang lebih adaptif terhadap dinamika pasar Indonesia. Oleh karena itu, teori portofolio modern perlu disesuaikan dengan karakteristik lokal agar lebih efektif dalam mendukung praktik investasi yang efisien dan berkelanjutan.
