Abstract

Abstract: The purpose of this study was to determine the relationship between math skills and chemistry learning outcomes of MAN 1 Medan students. This research is quantitative using basic linear regression analysis. The sample was taken by purposive sampling and a sample of one class was selected, namely XI MIPA 2. The instrument used was a test consisting of 10 essay questions on each chemistry question sheet of buffer solution and math ability. Analysis of research instruments was carried out with qualitative analysis and hypothesis testing was carried out with correlation and determination coefficient tests. The results of data analysis showed a positive and strong relationship between math ability and chemistry learning outcomes, this is evidenced by the acquisition of a sig value of 0.00 <0.05 and a correlation coefficient of 0.809. As for the contribution of the influence of math ability on chemistry learning outcomes of 65.4% to learning outcomes and other factors affect the remaining 34.6%. Keyword: Chemistry Learning Outcomes, Math Skills, Buffer Abstrak: Tujuan dari penelitian ini adalah untuk mengetahui hubungan kemampuan matematika dan hasil belajar kimia siswa MAN 1 Medan. Penelitian ini termasuk kuantitatif dengan menggunakan analisis regresi linier dasar. Sampel diambil secara purposive sampling dan dipilih sampel dari satu kelas, yaitu XI MIPA 2. Instrumen yang digunakan ialah tes yang terdiri dari 10 soal esai pada masing-masing lembar soal kimia larutan penyangga dan kemampuan matematika. Analisis instrumen penelitian dilakukan dengan analisis kualitatif dan pengujian hipotesis dilakukan dengan uji koefien korelasi dan determinasi. Hasil analisis data menunjukkan adanya hubungan positif dan kuat antara kemampuan matematika dan hasil belajar kimia, hal ini dibuktikan dengan perolehan nilai sig 0,00< 0,05 dan koefisien korelasi sebesar 0,809. Adapun untuk kontribusi pengaruh kemampuan matematika terhadap hasil belajar kimia sebesar 65,4% terhadap hasil belajar dan faktor lain memengaruhi 34,6% sisanya.

Abstract

PKBM Khalilah Insan Madani Medan konsisten dan berinovasi untuk memberikan warna baru dalam dunia pendidikan dan pengasuhan di kota Medan. Khalilah Mengusung konsep Fitrah Based Education dan bergerak sebagai institusi pendidikan non formal. Dalam meningkatkan dan menyeimbangan pendidikan formal dengan pendidikan formal di sekolah yang umum, Yayasan Khalilah selalu meningkatkan kompetensi guru-gurunya melalui pelatihan-pelatihan dengan para Pembimbing akademik di kota Medan agar dapat meningkatakan kompetensi siswanya baik dalam akademik maupun ketrampilan dalam menghadapi kehidupan sehari-hari. PKBM khalilah memliki program mengumpulkan minyak jelantah disetiap rumah siswanya sebagai cara untuk meminimalisir limbah rumha tangga. Kegiatan baik ini dapat menjadi modal dalam meningkatkan nilai ekonomis dari minyak jelantah. PKM yang dilaksanakan ini bertujuan untuk memberikan solusi dengan adanya edukasi pemanfaatan minyak jelantah dengan penyaringan biochar dari limbah biomassa menjadi sabun padat. Kegiatan ini direncanakan dilakukan dengan pendekatan sosialisasi dan metode pelatihan. Kegiatan ini meliputi: (1) pemaparan materi tentang Pemanfaatan minyak Jelantah, (2) Pelatihan pembuatan sabun padat dengan memanfaatkan minyaj jelantah, (3) Pelatihan mendesain kemasan sabun padat dengan penambahan minyak jelantah, (4) Pembimbingan dalam membuat manajemen usaha (5) review terhadap pelatihan yang telah dilaksanakan serta menarik kesimpulan. Diharapkan program kemitraan kepada masyarakat ini dapat memberikan pengetahuan dan pemahaman dalam mengolah minyak jelantah menjadi bahan sabun padat akan menjadi bekal bagi para guru dan peserta didik menjadi produk proses pembelajaran sehingga memberikan income generate bagi mitra.

Abstract

Shrimp in Indonesia are generally exported abroad after removing the head, tail, and skin. One alternative to the use of shrimp shell waste that has high economic value is processing shrimp shells into chitosan. The purpose of this study was to determine the shelf life of catfish using chitosan and to determine the optimal concentration of chitosan in catfish preservation. Chitosan applied to catfish showed that in the addition of a 0% chitosan solution, it had a shelf life of up to day 2 for 48 hours for a 0.5 solution; 1; 1.5 and 2% shelf life up to day 5 or for 120 hours. The most optimal concentration of chitosan for use in catfish is a 2% chitosan solution, and the total plate number (ALT) test meets the requirements of the SNI standard so that it can still be consumed.

Abstract

Porang (Amorphallus muelleri Blume) is one type of tuber plant that has the potential to be developed in Indonesia. Porang plants have been reported to contain chemical compounds that have antioxidant activity. This research was conducted on the leaves of the porang plant with the aim of knowing the antioxidant activity, characterization, and phytochemical profile of the compounds contained therein. Compound identification and characterization were performed using standard methods, and antioxidant activity was determined using the DPPH (1,1- Diphenyl-2-picrylhydrazyl ) method. The results of the identification of chemical compounds showed that the ethanol extract of porang leaves contained chemical compounds of alkaloids, flavonoids, tannins, saponins, and steroids. The results of the examination of the simplicia characterization of porang leaves included the soluble ethanol content of 33.93%, the water soluble extract content of 17.3%, the ash content of 5.58%, the acid insoluble ash content of 0.235% and the water content of 8%. From the results of the simplicia characterization, it shows that the results meet the specified requirements. The results showed that the ethanol extract of porang leaves had antioxidant activity with an IC50 value of 93.04 µg/mL, which in this case is included in the category of strong antioxidant activity. Meanwhile, as a comparison, Vitamin C was used, which has an IC50 value of µg/mL, which is included in the category of very strong antioxidant activity.
