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

Introduction: This study aims to explore the application of the AIDA+S marketing model in the marketing strategies of private universities for recruiting prospective Generation Z students to choose a campus. Methods: The type of research to be used is quantitative, associative, and descriptive. The population in this study consisted of all students actively studying at the Ahmad Dahlan Institute of Technology and Business. The sampling procedure employed in this study was non-probability, utilizing a purposive sampling technique, with a sample size of 150 respondents. The data analysis used was multiple linear regression analysis to determine the influence of several AIDA+S variables on the Decision variable of choosing a campus. Results: The results of this study concluded that the AIDA+S Model had a significant effect on the Decision to choose a campus. Furthermore, for the variables attention, interest, and desire do not have a substantial impact on the decision to select a campus among Generation Z. While for the variables action and satisfaction, there is a considerable influence on the decision to select a campus among Generation Z. The biggest reason respondents choose a campus because it is close to home according to the character of generation Z who choose convenience as the basis for consideration.Suggestion: First, attract Generation Z's Attention by creating engaging and easy-to-digest visual content, such as short videos, infographics, or memes. You can also use their favorite social media platforms. Second, Build Interest by showing the Benefits and Advantages of the campus. Third, Arouse Desire by uploading positive reviews from other customers to build trust and desire. and then provide limited offers or special discounts. Keywords: Marketing Model, AIDA+S, Decision to choose, Generation Z

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

Kilemo (Litsea cubeba (Lour.) Pers.), a forest tree species of the Lauraceae family, is naturally distributed in China, Taiwan, and Southeast Asia, including Indonesia. This species is valued for its high-quality essential oils and its potential applications in the biopharmaceutical and chemical industries. However, the semi-recalcitrant nature of kilemo seeds presents challenges in storage and germination, necessitating research to optimize seed quality and propagation methods. This study aims to evaluate the physical and physiological qualities of kilemo seeds sourced from highland regions in West Java and North Sumatra and to determine the best pretreatment methods to enhance germination performance. Seed samples were collected from Ciwidey, Mount Papandayan (West Java), and Aek Nauli (North Sumatra). The study assessed seed moisture content, purity, 1,000-seed weight, and seed viability. Different soaking treatments (plain water, boron solutions, KNO3 solutions, and coconut water) were applied, followed by germination tests under two sowing conditions: open seedbeds and plastic-covered seedbeds. The results indicate that kilemo seeds exhibit moisture content ranging from 13.01% to 14.68%, purity above 96.77%, and a weight of 1,000 seeds varying from 21.36 to 27.86 g. Germination trials revealed that seeds soaked in 100% coconut water for 3 or 6 hours exhibited the highest germination percentages and vigor, particularly in an open seedbed condition. These findings suggest that coconut water pretreatment enhances seed germination and viability, offering an effective method for improving the propagation success of kilemo. The study provides valuable insights into optimizing seed handling techniques to support the conservation and commercial cultivation of this species.
