The research test was carried out at the Biology Laboratory FKIP UISU. The study design used was a Completely Randomized Design (CRD) with 3 treatment tests and five replications, as a comparison of each treatment test used control.This study aims to determine the content of pesticides in Brassica chinensis in Medan city markets, whether pesticides are contaminated or not, and to determine student learning outcomes in biochemical subjects in additives and contaminants in food.In this study, the mortality of C. binotalis larvae was observed in each treatment test, starting from observations on Brassica chinensis leaf samples taken from control, then on Brassica chinensis leaf samples taken from Sambas market, Simpang Limun market, Halat market, and market Like Crowded. Observations were made at 6, 12, 24, 48, and 72 hours after application. The area of leaf damage was observed after 72 hours of application in each treatment test. Likewise, larval weight gain was calculated after 72 hours of application.After 72 hours of treatment test, the highest larval mortality occurred in Brassica chinensis samples taken from the crowded market at 6.22%, with the lowest larval weight gain of 570 mg, and with the least area of leaf damage that was 1,169 mm2. While the lowest larval mortality after 72 hours of treatment test occurred in Brassica chinensis samples taken from the control at 0.89%, with the highest larval weight gain of 588.8 mg, and with the most extensive leaf damage area of 5,486.3 mm2.Before conducting biochemical learning on material additives and contaminants in food to students, a pre-test was made to students, and the average value of student learning outcomes during the pre-test was 60.26 with a standard deviation of 10.09. Whereas after the learning material has been submitted and conducted a post test the average value of student learning outcomes has increased by 74.85 with a standard deviation of 6.25.

This study aims to: 1) recognize fruit flies (Drosophila melanogaster), 2) morphologically distinguish adult fruit fly sex, 3) study the growth of fruit fly populations. The practicum was held on August 20, 2019 in the Biology Education Laboratory FKIP UISU. The working principle of practicum is making food as a medium for fruit fly culture (a mixture of bananas, cassava tape, benzoate), etherization and observation, observing the growth of fruit fly populations. Observations were made by counting the number of live flies and dead flies, the sex ratio of flies. Observations were carried out every day, for 15 days (20 August 2019 - 3 September 2019). The results of the analysis show that: 1) population growth of Drosophila melanogaster includes logistic growth models with S-shaped curves, 2) sex of adult fruit flies can be morphologically distinguished through body size, abdominal shape, genital comb and external genital organs in the abdomen. Based on the results and discussion, the following conclusions are obtained: 1) fruit flies including insects undergoing perfect metamorphosis (egg phase, larvae, pupa, imago), 2) differences in adult fruit fly sex can be seen from body size, abdomen shape, presence of genital comb, external genital organs in the abdomen, 3) population growth of fruit flies including logistic growth models in the form of S curves, influenced by environmental factors

Jenis penelitian ini adalah kualitatif yakni dengan membandingkan karakter morfologi antara spesies dari familia Zingibercaeae yang dikoleksi dengan menggunakan metode jelajah. Hasil dari penelitian ini bertujuan untuk menghasilkan buku modul bahan ajar yang berisikan tentang spesies Famili Zingiberaceae di Kawasan Taman Buah Lubuk Pakam. Penelitian ini merupakan penelitian ekploratif. Pengumpulan data dimuali dari bulan juni hingga Agustus 2024 di Kawasan Taman Buah Lubuk Pakam. Pengambilan sampel menggunakan deksriftif eksploratif. Hasil yang diperoleh menunjukkan bahwa terdapat Tujuh spesies yang tergolong ke dalam familia Zingibercaeae yang ditemukan di Taman Buah Lubuk Pakam yaitu Zingiber monatum, Alpinia galanga, Curcuma zedoaria, Curcuma longa L, Curcuma Amada R Kaempferia galanga L, dan Amonum compactum. Ketujuh spesies tersebut memiliki beberapa persamaan dan perbedaan karakter morfologi. Persaamaan karakter antara lain dari sistem perakaran, bentuk akar, bentuk batang semu, arah tumbuh, tepi daun, serta bentuk daun. Sedangkan perbedaan karakter dapat dilihat dari permukaan batang semu, ujung daun, pangkal daun, permukaan daun, serta bentuk dan warna rimpang.
