Abstract

The Madura tribe is one of the major ethnicities in Indonesia that has a rich socio-cultural heritage with its own characteristics, ranging from the tradition of cow karapan and sonok cows, to strong values of solidarity and religiosity. However, the development of globalization poses challenges to the preservation of this culture, such as shifting the meaning of traditions, weakening social solidarity, and reduced use of the Madurese language among the younger generation. This research aims to analyze the socio-social and cultural values of the Madura people and examine how they adapt in the era of globalization. This research uses a literature study method by examining various sources in the form of books, articles, and scientific journals that are relevant about the socio-culture of the Madura people. The analysis is carried out by emphasizing aspects of social characteristics, cultural traditions, and challenges faced in the modern era. The results of the study show that although Madura culture faces serious threats due to modernization and negative stereotypes, noble values such as self-respect, mutual cooperation, and religiosity remain a strong foundation. Cultural preservation needs to be directed at innovation and digitalization to remain relevant in the future.

Abstract

This study aims to investigate the kinetics of the irreversible saponification reaction between triglycerides in cooking oil and sodium hydroxide (NaOH) by analyzing the changes in reactant concentrations over time. The reaction was carried out at 60 oC, and samples were collected every 5 minutes and analyzed by titration using 0.5 M HCl. The results showed that the concentration of NaOH decreased from 0.500 mol/L to 0.290 mol/L within 30 minutes, while triglycerides decreased from 0.203 mol/L to 0.133 mol/L. The kinetic data were evaluated using both second-order and pseudo first-order models to determine the most appropriate mechanism. The second-order model yielded an R2 value of 0.9069 with a rate constant of 0.0125 L-mol-1·min-1, whereas the pseudo first-order model exhibited better linearity with an R2 of 0.9296 and a rate constant of 0.0169 min-1. These results indicate that although the reaction is mechanistically bimolecular, the experimental conditions particularly the relative excess of NaOH caused the reaction to behave in accordance with pseudo first-order kinetics. Thus, the observed kinetic behavior is more accurately described by the pseudo first-order model, in which the decrease in triglyceride concentration plays a dominant role in controlling the reaction rate. This study provides further insight into the kinetic characteristics of saponification under laboratory operating conditions. AbstrakPenelitian ini bertujuan untuk mempelajari kinetika reaksi saponifikasi irreversible antara trigliserida dalam minyak goreng dan natrium hidroksida (NaOH) melalui analisis perubahan konsentrasi reaktan terhadap waktu. Reaksi dijalankan pada suhu 60 oC, dan sampel diambil setiap 5 menit untuk dianalisis melalui titrasi menggunakan HCl 0,5 M. Hasil pengamatan menunjukkan bahwa konsentrasi NaOH menurun dari 0,500 mol/L menjadi 0,290 mol/L dalam 30 menit, sedangkan trigliserida turun dari 0,203 mol/L menjadi 0,133 mol/L. Data kemudian dianalisis menggunakan model kinetika orde dua dan pseudo first-order untuk menentukan mekanisme reaksi yang paling sesuai. Model orde dua memberikan nilai R2 sebesar 0,9069 dengan konstanta laju 0,0125 L-mol-1·min-1, sedangkan model pseudo first-order menunjukkan linearitas lebih baik dengan R2 0,9296 dan konstanta laju 0,0169 min-1. Perbedaan ini menunjukkan bahwa meskipun reaksi secara mekanistik bersifat bimolekuler, kelebihan relatif NaOH menyebabkan reaksi tampak mengikuti pola pseudo first-order. Dengan demikian, kinetika teramati lebih akurat dijelaskan oleh model pseudo first-order, dimana penurunan konsentrasi trigliserida menjadi faktor pengendali utama laju reaksi. Hasil penelitian ini memperkuat pemahaman mengenai perilaku kinetika saponifikasi pada kondisi operasi laboratorium.

Abstract

Background: Postpartum care frequently prioritizes physical recovery while overlooking the psychological determinants of reproductive health. Purpose: To analysed the relationship between parental burnout and sexual dysfunction among postpartum women. Method: A quantitative cross-sectional study was conducted with 144 postpartum mothers at Community Health Center Ardimulyo using purposive sampling. Participants completed the Parental Burnout Assessment (PBA) and Female Sexual Function Index (FSFI). Data were analysed using Spearman’s Rho and Multiple Logistic Regression (p<0.05). Results: Prevalence of moderate-to-high parental burnout was 38.2%, with 54.2% of respondents at risk for sexual dysfunction. A significant negative correlation was identified (
