Abstract

Instant organoleptic test of ginger against three varieties of ginger (Zingiber officinale) is descriptive research. The purpose of this study is to examine the feasibility of processed ginger formulations and their effect on the level of preference of panelists as consumers for instant ginger as an herbal drink made from raw materials with three varieties of ginger. This research was conducted in May-July 2023 at the Production Laboratory of the Faculty of Agriculture-UWKS using a one-factor Complete Randomized Design (RAL) consisting of 3 levels. The treatment is the use of the main raw materials of ginger with 3 varieties, namely J1 = elephant ginger (2023 research results); J2 = red ginger; J3 = empirrit ginger. The observation parameters were carried out through Organoleptic tests on product properties, namely taste, aroma, texture, color, physical appearance, and knowing the level of preference of panelists for ginger instant drinks from 3 varieties of ginger, and each treatment was repeated three times with 10 panelists each repeat. This hedonic test with sensory analysis of instant ginger products is used to guess what products the panelists like the most with the level of liking. The method used in this Hedonic Test, consists of 5 levels: (1) very dislike, (2) dislike, (3) ordinary, (4) like, and (5) very like From the results of this study is expected to provide benefits to the public in consuming ginger as a healthy herbal drink, as well as for other researchers who are interested in similar research. Three levels in the treatment of the use of three varieties of ginger on instant results of ginger, from organoleptic tests give results that elephant ginger has advantages in aroma and color, empirrit ginger has the advantage of soft texture and red ginger has a good taste.

Abstract

This study aims to assess mathematics teachers' understanding of Mathematics Content Knowledge based on the Revised Bloom Taxonomy. The method used is quantitative descriptive research with a survey approach. The respondents of this study were mathematics teachers who taught at SMP/MTs in Losari District, Brebes Regency. Data was collected using non-test instruments in the form of questionnaires and question tests. Data analysis involves presenting data, testing differences, and concluding. The results showed that teachers' understanding of Mathematics Content Knowledge in teaching and mastery of the material was categorized as strong. Based on Bloom's revised taxonomy, teachers have good mastery, especially in knowledge dimensions such as factual, conceptual, procedural, and metacognitive knowledge, which are categorized as high. There was no significant difference in the average Mathematics Content Knowledge score of teachers, either with a working period of less than 10 years, 10-15 years, or more than 15 years.

Abstract

This article discusses the challenges and opportunities in adapting constitutional theory in the context of Indonesia's law and government. It was found that the main challenges include widespread corruption, political instability, plurality and multiculturalism, inconsistencies between national and local laws, and suboptimal enforcement of human rights. On the other hand, there are significant opportunities to overcome these challenges, such as through constitutional reform, the important role of the Constitutional Court, increasing legal education and awareness, the use of information technology for transparency, and international cooperation. This article emphasizes the importance of taking advantage of these opportunities and addressing existing challenges to develop a stronger, fairer, and more democratic constitutional system in Indonesia. Thus, the adaptation of constitutional theory can run more effectively and in accordance with the needs and aspirations of the people of Indonesia.

Abstract

This study aims to enhance the ability of Madrasah Aliyah mathematics teachers to develop Higher-Order Thinking Skills (HOTS) questions through training and mentoring. This research employs a qualitative approach with a case study design involving 20 mathematics teachers. Data were collected through questionnaires, observations, and document analysis, then analyzed using thematic and descriptive statistics. The findings indicate that teachers' understanding of HOTS principles, reasoning levels, and question formulation steps after participating in the training significantly improved, with an average increase of 55–70% across key indicators. However, some teachers still struggled to integrate real-world contexts into the HOTS questions they developed. These findings highlight the importance of continuous professional development programs to strengthen teachers' competency in designing HOTS-based assessments. Further research is needed to explore the long-term impact of this training on student learning outcomes.
