Abstract

Bahasa Indonesia telah menjadi bagian integral dari kehidupan sehari-hari di Indonesia dan memiliki peran penting dalam mempertahankan identitas budaya bangsa. BIPA adalah program keterampilan belajar berbahasa Indonesia yang dikhususkan bagi penutur asing, mulai dari berbicara, menulis, membaca, dan mendengarkan. Penelitian ini menggunakan metode literatur review yang memiliki struktur atau tahapan yang berbeda dengan penelitian eksperimental atau survei. Penelitian ini berfokus penelitian kualitatif dengan pendekatan sekunder tentang bahasa Indonesia sebagai penutur asing sebagai upaya internasionalisasi bahasa Indonesia. Desain penelitian ini digunakan bertujuan untuk memberikan pemahaman komprehensif tentang topik tertentu dengan menelaah berbagai perspektif dan temuan dari studi-studi terdahulu. Hasil penelitian ini menunjukkan bahwa BIPA dapat menjadi salah satu cara efektif untuk menginternasionalisasi bahasa Indonesia, memperkuat diplomasi kebudayaan, dan mendukung keaktifan serta pemahaman lintas budaya oleh pelajar BIPA.

Abstract

This research aims to explore creative approaches in ice cream production by utilizing the effect of freezing point depression. Through these experiments, we employed various additives that influence the physical properties of ice cream, resulting in a final product that is softer, creamier, and able to maintain optimal texture at different temperatures. The experimental method involved varying the types of additives combined with the base ice cream mixture. The measured parameters included freezing point depression, texture, and softness of the produced ice cream. The collected data were analyzed to determine how each additive affected the physicochemical characteristics of the product. The results showed that differences in sugar content among the ingredients significantly influenced the degree of freezing point depression in the ice cream.

Abstract

This study examines the effects of selected organic and inorganic compounds on the electrical conductivity of salt solutions. Organic substances (sugar, coffee, tea, and a surfactant-based cleaner) and inorganic additives (ammonium chloride in cough medicine, povidone–iodine, and carbonated beverage) were mixed with salt solutions at varying concentrations to evaluate their influence on ion availability and mobility. The results show that conductivity increases proportionally with salt concentration, confirming that ion content is the primary factor governing charge transport. Inorganic ionic additives significantly enhanced conductivity by releasing additional ions into the solution, whereas non-ionic organic compounds consistently reduced conductivity at low salt levels by diluting ionic species and hindering ion mobility. Conductivity in organic mixtures increased only when salt concentration became dominant. These findings highlight the contrasting mechanisms of organic and inorganic additives in modifying electrolyte behavior and provide useful insight for chemistry education and simple electrochemical analysis.
