Abstract

Increased activity in the Badung river basin has an impact on water quality, including river estuaries and the sea, which will affect the environmental ecosystem. One of the water and sediment pollutants is heavy metals. Heavy metal pollution can be overcome with phytoremediation. This research aims to analyze the ability of the Rhizophora apiculata and Sonneratia alba mangroves to accumulate the heavy metals Pb and Cu.  Phytoremediation naturally occurs at river estuaries, namely in mangrove plants. Metal absorption in mangroves occurs in the roots which are then carried to the leaves. The research was conducted at the mouth of the Badung River, Denpasar, Bali. The research results show that the Pb metal content in water has exceeded the quality standards for marine tourism and marine biota based on PPRI No. 22 of 2021, namely an average of 0.005 mg/l. Metal absorption occurs in two types of mangroves, namely Rhizophora apiculata and Sonneratia alba. The highest metal absorption in mangroves is the Sonneratia alba species. Mangroves translocate metals from roots to leaves. From the research results, mangroves are classified as low accumulator plans.

Abstract

The purpose of this study was to determine the value of the modulus of elasticity and sugar content in Wajik snacks. Wajik is one of the traditional snacks that is popular with many people. The sweet and legit taste of wajik increases consumer interest in this product. This product is a semi-wet food made from glutinous rice, coconut milk and brown sugar. Coconut milk is a mandatory additional ingredient in making wajik, because the oil produced by coconut milk will produce a legit and savory taste. Coconut milk also produces fat in wajik. Elasticity was analyzed from 5 samples of wajik snacks and Analysis of sugar content (fructose, glucose, sucrose) was carried out using the high performance liquid chromatography (HPLC) method and total calorie analysis was carried out by adding calories from protein, fat, carbohydrate components or by calculation method. Protein content was analyzed using the Kjeldahl method, total fat analysis was carried out using the Weibull method, total carbohydrates were determined using the by difference method.

Metode yang digunakan dalam penelitian ini adalah kualitatif-deskriptif. Hasil dari penelitian ini adalah tingkat kesulitan mahasiswa kelas A masuk dalam kategori mudah dengan persentase 39,0% memilih kategori mudah. Sedangkan, mahasiswa kelas C mengalami tingkat kesulitan saat melakukan praktikum hingga sebesar 44,1% dengan kategori sulit. Penggunaan asisten praktikum terbukti sangat membantu mahasiswa dalam pelaksanaannya. Hal tersebut dapat dilihat melalui diagram faktor keberhasilan praktikum yang menunjukkan bahwa peran asisten sama dengan peran dosen sebesar 19,8%. berdasarkan hal tersebut, dapat disimpulkan bahwa kontribusi asisten praktikum terbukti efektif dalam pembelajaran elektronika analog di kelas. Kata Kunci: elektronika analog, asisten praktikum, efektivitas Abstract The existence of skilled and competent practicum assistants can support the success of the practicum learning process and help students so that the difficulties faced can be resolved, so this study aims to determine the effectiveness of assistance between the two classes described descriptively. The method used in this research is qualitative-descriptive. The results of this study are the difficulty level of class A students in the easy category with a percentage of 39.0% choosing the easy category. Meanwhile, class C students experienced a level of difficulty when doing practicum up to 44.1% in the difficult category. The use of practicum assistants proved to be very helpful for students in its implementation. This can be seen through the practicum success factor diagram which shows that the role of the assistant is the same as the role of the lecturer by 19.8%.

Abstract

This study aims to analyse the validity and reliability of an instrument for assessing reflective thinking skills on the topic of wave-particle dualism in modern physics lectures using the Rasch model. The Rasch model was selected for its capability to provide a more in-depth analysis of item performance and respondent ability, as well as to identify misfitting or biased items. The research method employed is a descriptive quantitative approach, utilizing Winsteps software for data analysis. The sample consists of 36 students enrolled in modern physics lectures at a university in West Nusa Tenggara. The results indicate that the instrument has excellent item reliability (0.91) and excellent internal consistency (Cronbach's Alpha 0.86), although the respondent reliability falls into the weak category (0.62). The instrument's validity also meets the Rasch model's acceptance criteria, with infit MNSQ and outfit MNSQ values ranging from 0.5 to 1.5. Further analysis reveals that some items are misfitting and need revision to ensure fairness and consistency in measuring reflective thinking skills. These findings make a significant contribution to the development of more accurate and reliable assessment tools in physics education

Abstract

Kitosan merupakan biopolimer turunan dari hasil deasetilasi kitin, yang berkembang pesat di dunia medis saat ini. Kitosan salah satu material yang memiliki sifat anti mikroba, biokompatibel, dan biodegradable sehingga aman bagi tubuh manusia. Penelitian ini dilakukan untuk mengidentifikasi pengaruh daya gelombang mikro terhadap karakteristik kitosan. Pembuatan kitosan dengan mengisolasi kitosan dari cangkang kerang Mutiara (Pinctada maxima sp) melalui proses deproteinasi, demineralisasi, dan deasetilasi. Kitosan di analisis gugus fungsi, derajat deasetilasi, rendemen, berat molekul, dan struktur kristalnya. Pada tahapan deasetilasi mengunakan NaOH 60%. Hasil penelitian menunjukkan bahwa pemberian gelombang mikro dengan daya high selama 5 menit memperoleh nilai derajat deasetilasi tertinggi 83,40%, rendemen akhir sebesar 8,2%, dan berat molekul 222.185,94 Da, serta memiliki derajat kristalinitas sebesar 59,09%. Derajat deasetilasi kitosan meningkat seiring dengan naiknya daya gelombang mikro sedangkan berat molekul yang dihasilkan berbanding terbalik dengan derajat deasetilasi.
