KEMAMPUAN REPRESENTASI MATEMATIS SISWA STREESMUTPRAKAN SCHOOL THAILAND DALAM MENYELESAIKAN SOAL PISA
Full text linkAbstract: The ability of mathematical representation is very important to solve mathematical problems, because every solution must use mathematical representation. This research was conducted at Thailand's Streesmutprakan School because according to the results of the 2015 PISA test, mathematical representation skills also affected the execution of the PISA test. The PISA test results in 2015 showed that the Mathematics ability of Thai students was ranked 54th out of 70 countries with an average score of 415. While the average score for Mathematics from all countries taking the PISA test was 490. The results showed that Thailand was still in in a position below the average. The method used in this research is descriptive qualitative, by giving PISA questions about shape and space content. The results of this study indicate that students with high abilities are superior in visual mathematical representation. This can be seen from the number of cube nets that can be drawn with different models. The indicator of mathematical expression is only one of six students who can meet the indicator and answer correctly. For indicators of the ability to represent in words or written texts, students with high abilities are also more prominent because they have a reason for each answer, whereas for students with medium and low abilities only guess even silence during interviews.

DETEKSI FORMALIN PADA IKAN ASIN MENGGUNAKAN UBI JALAR UNGU (Ipomea batatas L.)
Full text linkThe content of formalin in salted fish needs to be known by the public in an easy and inexpensive way. Purple sweet potato (Ipomoea batatas) is one of the plants that contains anthocyanin which will show a color change when reacted with formalin. This study aims to determine whether purple sweet potato extract can detect formalin content in salted fish. The method used is a pure experiment with 5 treatments and 5 replications. Salted fish samples were made by the researcher himself, while purple sweet potato was extracted with a dose ratio of 1:1, 1:2 and 1:3 (v purple sweet potato extract /v aquadest). The observation parameter was the time when the color changed from purple to reddish in the salted fish sample after being dripped with purple sweet potato extract. The data were analyzed statistically using the Kurskall-Wallis test and continued with Duncan's test. The results of the analysis showed that purple sweet potato extract could detect the presence of formalin in salted fish samples (p < 0.05). The treatment with a dose of 1: 1 was able to detect the fastest formalin content at 735.40 seconds compared to treatment 1: 2 (915.20) and treatment 1: 3 (1038.40). This time is close to the time required by the positive control treatment (607.80). The conclusion of this study confirms that purple sweet potato can be used by the public to detect formalin content in food.
