Soursop plant parts that are often used by the community, namely the fruit and leaves. Ripe soursop fruit is usually developed to produce juice and lunkhead products. Ripe soursop fruit contains vitamin C which is known to have a wrong function, namely to increase immunity, so that it can protect the body from pathogens. Soursop leaves are often used by the community in the form of a decoction of the leaves for traditional medicine. The research about antioxidant test on ethanol extract of soursop leaves (Annona muricata Linn) had been conducted using DPPH method (1,1-diphenyl-2-picrylhdirazyl). This research aims to indicate the antioxidant activity of soursop leaves. Samples were collected from Lambaro Skep, a region of Banda Aceh. Then, the sample was dried by air before macerated using ethanol 96%. After that, the filtrate is evaporated using rotary evaporator and concentrated again using a hairdryer. The concentrated extract is then tested for antioxidant activity using DPPH method at maximum wavelength of 517 nm. The result shows young soursop leaves extract has 14.462 ppm of IC50 value, while old soursop leaves extract has IC50 value of 9.626 ppm.

Telah dilakukan penelitian pengembangan soal-soal kimia materi hidrokarbon dan minyak bumi bermuatan nilai-nilai (Value based Questions-VBQs) untuk memperkokoh karakter siswa SMA. Penelitian ini bertujuan untuk menghasilkan soal-soal kimia SMA bermuatan nilai-nilai karakter. Nilai-nilai yang terdapat pada soal yang dikembangkan adalah nilai-nilai: intelektual, spiritual, etika, estetika, sosial dan ekonomi. Penelitian ini menggunakan metode penelitian dan pengembangan melalui tahapan pendefinisian, analisis materi dan indikator (define), desain soal (design) dan pengembangan soal (develop). Subjek penelitian yaitu siswa SMAN 1 Banda Aceh kelas IX yang diambil secara purposive sampling dan jumlah siswa yang terlibat pada tahap diseminasi sebanyak 15 orang untuk melihat keberterimaan siswa terhadap soal. Soal yang telah dikembangkan divalidasi oleh pakar pendidikan kimia dan guru MGMP kimia kota Banda Aceh, hasilnya menunjukkan bahwa soal yang dikembangkan layak untuk diujicobakan pada siswa. Rata-rata hasil penilaian kelayakan soal sebesar 87%. Hasil tanggapan keberterimaan soal oleh peserta didik menunjukkan persentase sangat setuju sebesar 30%, setuju 50%, tidak setuju 20% dan sangat tidak setuju 0%. Berdasarkan hasil penelitian dapat disimpulkan soal-soal bermuatan nilai yang dikembangkan dapat diterima oleh guru, layak diaplikasikan dan dipergunakan untuk mengukur hasil belajar siswa. Perlu penelitian lanjutan untuk mengembangkan soal-soal bermuatan karakter bagi materi-materi ajar mata pelajaran kimia lainnya.

Publisher : FKIP USK

This study aims to determine the level of students' understanding of each indicator of the buffer solution material and to determine the most difficult indicator in understanding the buffer solution material using the Four-Tier Multiple Choice diagnostic test. This type of research uses a descriptive type of research using a qualitative approach. The subjects of this study were students of class XI Madrasah Aliyyah Swasta Darul Ihsan as many as 15 students who were selected using the simple random sampling technique. The research instrument used was the Four-Tier Multiple Choice diagnostic test instrument sheet and student interview sheets. The results of this study showed that the average percentage of students who understood the concept was 32.3%, did not understand the concept was 38.1%, misconception was 20.6% and the error was 9%. Based on this research, it was found that the most difficult indicator to understand is the indicator to determine the relationship between the buffer solution and the concept of chemical equation and the indicator to calculate the pH of the acid buffer solution. So it can be concluded that the students of class XI Madrasah Aliyyah Private Darul Ihsan have difficulty in understanding the material of the buffer solution.

The activity of using mercury in gold mining in Alue Baro Village, Meukek District is carried out freely so that it has a negative impact on the environment and the health of the miners. This study aims to determine the level of mercury in the hair of artisanal gold miners in Alue Baro village by referring to the reference that has been set by WHO. The data sample collection was carried out by taking 6 hair samples from the Alue Baro village gold miners who were selected with various types of work, namely gold processing, waste processing and waste waste until the time of the interview with a minimum working period of 1 year with sample codes R1, R2, R3, R4, R5 and R6 as control samples. The six samples were analyzed using Atomic Absorption Spectrophotometry equipped with a Mercury Analyzer which showed results, respectively, 1.01; 2.38; 1.65; 1.35; 1.66; and 0.64 ppm. The results of this study indicate that all hair samples have mercury levels above the mercury threshold that has been set by WHO, namely 1 ppm. High levels of mercury in hair samples were analyzed on exposure to mercury. Further research was conducted to analyze other metals contained in the hair of gold miners in Alue Baro village
