Abstract

Blondo is a by-product of VCO production, commonly used for feed despite its rich nutrition and physiological properties. To reutilize blondo and take advantage of its nutrition, blondo probiotic ice cream is developed as a plant-based functional food. Determining the shelf-life of food products is very important because it reflects the product's durability during the time interval between production and consumption. This study aims to determine the shelf-life of blondo-based probiotic ice cream using the Accelerated Shelf-Life Testing (ASLT) method with the Arrhenius model. Blondo-based probiotic ice cream was stored for 28 days at temperatures of -6℃, -11℃, and -18℃. The parameters observed were total Lactic Acid Bacteria (LAB), total acid, pH value, and total solids. The results of the calculation of the Arrhenius model selected the total LAB parameter as a critical parameter. Therefore, we considered using the term “best before” to refer to probiotic efficacy instead of shelf-life. The blondo-based probiotic ice cream is best consumed before if stored at -6℃ is 206.80 days or 6 months 27 days; at -11℃ is 186.47 days or six months 6 days; and at -18℃ is 160.22 days or 5 months 10 days.

Abstract

The problem found in the field is that HOTS or higher-order thinking Skills in Indonesia are not optimal. Teachers in schools are not fully prepared to implement assessments based on Higher-Order Thinking Skills. This study aims to analyze the strategy of integrating History learning based on higher-order thinking Skills in high schools throughout Yogyakarta. The study used a qualitative method with a descriptive approach. The research sample was selected sequentially from the principal, vice principal for curriculum, History subject teacher, and samples of grade X, XI, and XII students at SMA Negeri 3 Yogyakarta. Data collection techniques include observation, interviews, and documentation. Furthermore, data analysis was carried out using Miles, Huberman, and Saldana's data analysis techniques, namely collection, condensation, presentation, and conclusion. The results of the study showed that the HOTS integration strategy in high schools throughout Yogyakarta consisted of planning, implementation, and evaluation. Second, the obstacles to integrating HOTS-based learning are related to human resources, specifically the ability of teachers to integrate IT-based HOTS, time allocation with unbalanced discussion materials, and student's ability to comprehend diverse materials. Teachers responded by turning obstacles into opportunities. The impact of HOTS is studied from the cognitive, affective, and psychomotor domains. Each teacher has implemented unique and diverse teaching. The study's implications suggest that educational outcomes should prioritise the process and results of critical thinking, focusing on students who are knowledgeable and also morally and ethically intelligent.

Abstract

The bud chip technique is an important method in sugarcane propagation, as it enables the production of a large number of seedlings while using less planting material. However, the small size of the bud cuttings results in limited nutrient reserves and endogenous hormones, which may constrain early seedling growth. Therefore, optimizing the composition of the growing media and applying plant growth regulators (PGRs) are necessary to enhance seedling growth and development.This study employed a factorial Randomized Complete Block Design (RCBD). The objectives were to determine: (1) the appropriate composition of growing media for sugarcane seedlings using the bud chip technique; (2) the effects of different concentrations of plant growth regulators (PGRs) on seedling growth; and (3) the interaction between growing media composition and PGR concentration on the growth of sugarcane seedlings. The results indicated that: (1) the use of topsoil combined with cow manure, as well as topsoil combined with cow manure and rice husk compost, resulted in comparable seedling growth, both of which were superior to the control, as reflected in shoot height, leaf number, and shoot-to-root ratio. However, no significant differences were observed among treatments in terms of time to 50% sprouting and growth percentage; (2) different concentrations of PGRs did not significantly affect seedling growth across all observed variables; and (3) no interaction was found between growing media composition and PGR concentration on sugarcane seedling growth.
