Abstract

Pongamia (Pongamia pinnata) is a non-food plant that has the potential to be developed as a biofuel because its seeds’ oil content is up to 40%. Therefore, it is necessary to study the characteristics of seeds for germination in relation to mass cultivation and information on oil content as a production consideration. This paper aimed to describe the sensitivity of pongamia seed moisture content to germination and its oil content and also to understand the seed category. Variations in moisture content were obtained from storing seeds at ambient temperature for up to 5 months. Moisture content, morphological characters, oil content, and germination rate were examined for each storage period. Data were analyzed using analysis of variance to determine the treatment effect. The results showed that storing seeds at ambient temperature caused a decrease in moisture content. A decrease in moisture content of 29.36% in the first month’s storage significantly affected the reduction of morphological characters and seed weight. Meanwhile, during the 2–5 months storage period, the decrease in moisture content was only 2–5% and did not affect seed length. Reducing moisture content (MC) increased oil recovery but was not statistically significant. The best germination rate was 84.67%, obtained from fresh seeds (MC of 46.64%); the germination rate decreased as the moisture content decreased during storage. Pongamia should be categorized as an intermediate seed based on the seed moisture content characteristics and germination test results. Keywords: germination, moisture content, oil content, Pongamia pinnata, storage

Abstract

Postpartum blues merupakan gangguan psikologis yang dialami ibu pasca melahirkan. Rumah sakit di Indonesia belum banyak melaporkan tentang kejadiannya. Rendahnya ketertarikan ibu terhadap bayinya merupakan dampak dari postpartum blues. Penelitian ini bertujuan untuk mengidentifikasi hubungan kejadian postpartum blues dengan motivasi ibu untuk menyusui di RS Al-Islam Bandung. Metode penelitian yang dilakukan adalah deskriptif korelasi dengan pendekatan cross sectional yang melibatkan 122 ibu postpartum hari ke-3 sampai hari ke-14. Instrumen untuk postpartum blues menggunakan Edinburgh postnatal depression scale (EPDS) dan motivasi menyusui dengan instrumen Breastfeeding motivation instrucsional measurement scale (BMIMS). Data dianalisis dengan korelasi Spearman rank. Hasil penelitian menunjukan bahwa 53,3% dari 122 responden mengalami postpartum blues, dan dari 65 responden yang mengalami postpartum blues 36 orang (55,4%) memiliki motivasi menyusui yang rendah. Hasil uji korelasi menunjukan terdapat hubungan negatif antara kejadian postpartum blues dengan motivasi ibu untuk menyusui, dengan p value 0,02 (r = -0,288). Dengan tingkat kekeliruan 5%. Simpulan dari penelitian ini yaitu semakin tinggi kejadian postpartum blues pada ibu postpartum maka semakin rendah motivasi ibu untuk menyusui. Diharapkan perawat dapat mendeteksi lebih awal kejadian postpartum blues dan dapat memberikan informasi pada ibu dan keluarga tentang gangguan psikologis ibu post partum.

Abstract

Malapari (Pongamia pinnata (L.) Pierre) is one of the most potential biodiesel raw materials to be developed in Indonesia. The plant is natura ly distributed from Sumatera to Papua. However, oil content and its physico-chemical properties of malapari originated from Java was limitedly known. This study investigates chemical composition of malapari seeds, identifies fatty acid composition of the produced seed oil and characterises physico-chemical properties of malapari oil. Composition of chemical content of malapari seeds was analyzed through proximate analysis. Physico-chemical properties of malapari oil were analyzed using the ASTM test method. Results showed that Batukaras population is the best population to be used as biodiesel raw material source because it has the highest value of oil content. Besides, the Batukaras population has the lowest specific gravity, viscosity and acid value. Malapari oil is dominated by oleic and linoleic fatty acids which are potentia ly unsaturated fatty acids for biodiesel. Value of fatty acids (oleic and linoleic) and physico chemical properties (specific gravity and calorific value) of pongamia crude oils suggested that the five populations have been eligible for biodiesel feedstock.

Abstract

This study aims to evaluate the effectiveness and implementation dynamics of the Taqwa Curriculum Model within the context of Islamic homeschooling. The research was conducted at Tahfidz Homeschooling Sulaiman Baladil Huffaadz Elementary School in Bandung over a period of 61 days, utilizing a qualitative case study approach. A total of 17 participants, selected from among teachers and students, were involved in semi-structured interviews. Data were analyzed using a six-step thematic analysis technique. The results indicate that the Taqwa Curriculum Model effectively integrates Al-Qur’an memorization with religious understanding and student character development, which is significantly mediated by active parental involvement through daily Muraja’ah practices. Theoretically, these findings reinforce the concept of Fitrah-based education and the repositioning of the family as the primary educational unit. Practically, the implications emphasize the importance of a supportive learning ecosystem and humanist evaluation methods. Policy recommendations are directed toward the formal recognition of value-based curriculum quality standards within informal education pathways and the provision of structured pedagogical guidelines for parents to ensure the sustained quality of national Islamic education. Further research employing quasi-experimental or longitudinal approaches is recommended to obtain more robust evidence regarding the effectiveness of the Taqwa Curriculum Model.
