This study aimed to determine whether didactic anticipation with teaching aids could overcome students' epistemological obstacles in exponential material at Grade IX MTs Islamiyah Pontianak. The research method used in this research is Didactical Design Research (DDR) with a qualitative approach. The data source for this research comprised Grade IX students, and the data included the answer sheets from the pre-test, post-test, and the results of the interviews. The research subjects were three individuals selected using the purposive sampling technique. The results of the study show the epistemological obstacles encountered by the research subjects prior to the didactic anticipation treatment with props, including conceptual obstacles, procedural obstacles, and operational technique obstacles. The didactic anticipation designed to mitigate these obstacles comprises the didactic situation, assignment, expected response, possible difficulties, and anticipation. In anticipation of students' difficulties, teaching aids are employed, namely squares, cubes, paper, and PLAKAT. Changes in epistemological barriers after didactic anticipatory treatment showed that the epistemological barriers experienced by the subjects were reduced. This can be seen from the percentage of reduction in conceptual, procedural, and operational technical obstacles of 77.78%, 50%, and 25%, respectively. Based on the analysis of the changes that occurred, it can be concluded that didactic anticipation with teaching aids can overcome most of the epistemological obstacles of students in grade IX exponential materials.

Ethnomathematics-based learning grounded in the Qur’an is highly essential for religious-based schools as a strategic step to optimize the learning process. One promising approach is the development of Qur’an-integrated mathematics teaching materials. Unfortunately, many of these developments end after a single trial, despite the necessity of periodic and systematic evaluations. This study aims to continue the previous development of a mathematics leaflet sourced from the Qur’an and enhanced with QR code integration, by further examining its effectiveness and practicality. This study employed a quantitative research method, using a set of four validated test items. The content of the inheritance problem used in the test was adjusted to align with the learning outcomes in the fiqh subject, particularly in the topic of inheritance distribution. In addition to the test, the instruments used to assess practicality included an observation sheet and a student response questionnaire. Students who are the subjects are at the junior high school / equivalent level, precisely in class VII. In terms of effectiveness, the test results showed an average class score of 78.3, with 100% of students achieving the minimum mastery criteria (KKM), categorized as "very good." Regarding practicality, the average score from the observation sheets was 3.86, falling into the “very good” category, while the average student response score was 4.66, also classified as “very good.” The teaching materials produced are categorized as effective and practical and can integrate Islamic mathematics learning media and modules.

The presence of pulp in cocoa seeds is known to inhibit seed germination and seedling growth. The conventional method of removing pulp from cocoa seeds is done mechanically by rubbing the seeds with rubbing ash. Conventional pulp removal has disadvantages, such as being less practical and potentially damaging the seed surface. Therefore, it is necessary to try chemically removing the pulp from cocoa seeds by soaking the seeds in a lime solution (CaCO3). This study aims to determine the effect of the duration of cocoa seed soaking in CaCO3 solution and different planting media compositions on seedling growth. The research was conducted from September to December 2021 at a plastic house in Labuhan Dalam Village, Tanjung Senang District, Bandar Lampung, and the Seed Laboratory, Faculty of Agriculture, University of Lampung, Gedong Meneng, Bandar Lampung. The study used a Completely Randomized Design (CRD) arranged in a factorial manner. The first factor was the duration of cocoa seed soaking in CaCO3 solution, consisting of no soaking, soaking for 30, 60, 120, and 240 minutes. The second factor was the planting media composition, consisting of a mixture of rice husk charcoal + manure, sand + manure, and sand + rice husk charcoal + manure. Each treatment combination was replicated three times, resulting in 45 experimental units. The observation data were analyzed using analysis of variance, and the mean differences were tested using the Least Significant Difference (LSD) test at the 5% level. The results of the study showed that the duration of cocoa seed soaking in CaCO3 solution had no effect on cocoa seedling growth. The planting media composition of sand + rice husk charcoal + manure had a significant effect on the best cocoa seedling growth compared to the planting media compositions of rice husk charcoal + manure and sand + manure. Soaking cocoa seeds in CaCO3 solution had no effect on cocoa seedling growth in different planting media. Keywords : Cocoa seeds, pulp, CaCO3, soaking, planting media
