Abstract

This study aims to determine the interests and motivations of students in learning chemistry by utilizing YouTube as an alternative platform in distance learning. This type of research is descriptive quantitative research. Data were obtained from the survey of interest and motivation questionnaires using google forms taken for five weeks during the learning process. The respondents of this study were 100 students majoring in chemistry who studied organic chemistry using YouTube as a distance learning platform. The results showed that youtube as an alternative platform for distance learning (DL) is considered very good for positively impacting students' interest and motivation in studying chemistry. But in its use, it must be accompanied by applications or other media that can support the learning process, especially on material related to the experiment. In addition, in using YouTube, it is necessary to pay attention to aspects such as sound quality, image quality, size of writing, and clarity of the material so that the material presented is easy to understand, straightforward and exciting.

Abstract

Nabeez water or dates infused water is the Prophet Muhammad’s favourite drinks. Flavonoids, phenols, alkaloids, and beta D-glucan in dates have anticancer and antitumor activity. This study aims to prepare and characterise the active component of nabeez water made with ajwa dates, applied in BRM (Brown Rice Milk) products. BRM is an innovative plant-based beverage made with brown rice and nabeez water from ajwa dates as a halal beverage for immune booster in the era of the covid-19 pandemic. The methods to analysis the products are the preparation of nabeez water, the pasteurisation method for halal drinks with the LTLT (Low-Temperature Long Time) method, toxicity testing, pyrochemical testing, functional group analysis using FTIR instrument, milk dye degradation analysis and stability test. The results showed phenolic, flavonoids, catechol tannins, saponins, alkaloids, Mayer's test, and Wagner's test in halal drinks but not shown the tannin of gallate, anthraquinone, steroid test, and triterpenoid test. The toxicity test using the Brine Shrimp Lethality Test (BSLT) method of the LC50 value showed the Concentration 50 (LC50) value is 721.56 ppm. Analysis of functional groups using FTIR showed absorption of functional groups such as OH (hydroxide), C=O, C=C, C=CH, and Ar-H.

Abstract

Pengembangan tes dalam bentuk bentuk butir soal pilihan ganda sebanyak 13 soal, bertujuan untuk mengukur kemampuan siswa pada pokok bahasan alkil halida. Penelitian menggunakan metode kuantitatif deskriptif. sebanyak 92 mahasiswa yang telah mempelajari senyawa alkil halida dari mata kuliah kimia organik. Kelayakan yang dianalisis dengan model Rasch pada program Winsteps, meliputi tingkat kesulitan soal, validitas aitem, validitas konstruk, validitas konten, dan reliabilitas instrumen. Diperoleh hasil sebaran tingkat kesulitan soal yang merata, sehingga dapat mengukur kemampuan siswa di berbagai level pengetahuan. Validitas konstruk dibuktikan dengan nilai raw variance sebesar 40,2%, dan validitas konten menunjukkan soal-soal fit dengan model Rasch. kelayakan instrumen juga terlihat dari nilai relibilitasnya yang sangat baik yakni 0,96. Soal-soal yang dikembangkan, dapat menjadi alat ukur keberhasikan perkuliahan kimia organik, khususnya pada pembahasan senyawa alkil halida.
