Abstract

The lack of blood type test practicum is carried out this results in student learning outcomes where students are still having difficulties and are wrong in determining blood type and students are not creative in solving problems, because learning is focused on the teacher. This studied aims to improve student learning outcomes through the practice of blood type test based on Problem Based Learning (PBL) for class XI students. This research is a Classroom Action Research (CAR) carried out in two cycles with each cycle consisting of planning, action implementation, observation and reflection. The subjects in this study were students of class XI IPA in the academic year 2019/2020, amounting to 22 students consisting of 8 boys and 14 girls. Data collection techniques through observation, practice, and tests. Based on the results of the study obtained an average student learning outcomes in the first cycle of 66.67 with a percentage of mastery learning classically 31.81% and in the second cycle experienced an increase obtained an average student learning outcomes 88.82 with the percentage of mastery learning classically 90 , 90%. Based on these results it can be concluded that the application of the blood type test practicum with the Problem Based Learning strategy can improve student learning outcomes.

Abstract

ABSTRACT. Research has been carried out to determine the content of the bacterium escherichia coli in well water dug in the sub-district of Lirung, regency of the Talaud Islands. Water is one of the sources of living needs of living things, humans, animals and plants. Well water is a means of clean water from the soil for daily use, such as drinking water, cooking, washing and bathing. Therefore, the water must be pollution-free and meet the quality requirements for clean water. e.coli bacteria are bacteria that generally live in the intestines of humans and animals. This research uses a quantitative descriptive method. The results showed that 9 samples of water wells taken from 3 sites in the Lirung sub-district, in the regency of the Talaud Islands, contained e.coli bacteria which exceeded the maximum threshold not in accordance with the regulations of the Ministry of Health RI No.  416 / MENKES / PER / IX / 1990   Keywords: Bacteria Escherichia coli, Dug Well Water.

Abstract

Kandungan insektisida alami dari ekstrak daun, kulit batang dan biji pangi (Pangium edule Reinw.) untuk mengatasi larva Crocidolomia binotalis telah dilakukan di laboratorium. Penelitian ini telah dilakukan untuk mengetahui pengaruh penggunaan insektisida nabati untuk mengendalikan C.binotalis yang merupakan hama tanaman sawi. Penelitian ini bertujuan untuk menentukan konsentrasi ekstrak yang paling efektif dan konsentrasi ekstrak paling aktif; untuk mengevaluasi tingkatan konsentrasi ekstrak pada larva yang diujicobakan; dan untuk mengkarakterisasi kandungan fitokimia dari ekstrak daun, kulit batang dan biji pangi (Pangium edule Reinw.) Penelitian ini adalah penelitian eksperimen dan dimulai dengan tes skrining fitokimia untuk mendapatkan hasil metabolit sekunder di dalam ekstrak. Selanjutnya, diikuti dengan uji LC/LD50-48h terhadap larva instar III dari hama C.binotalis. Kemudian, ekstrak fraksi n-heksan dan etanol digunakan untuk perlakuan rancangan acak lengkap (RAL) dengan ANAVA dan diikuti dengan penghitungan nilai LD50-48h dengan menggunakan analisis probit. Hasil penelitian menunjukkan bahwa konsentrasi ekstrak biji pangi dengan menggunakan fraksi n-heksan lebih efektif dalam meningkatkan mortalitas larva dengan nilai LD50-48h = 11,25 mg/L. Sedangkan ekstrak kulit batang memiliki nilai LD50-48h = 30,20 mg/L dan nilai LD50-48h = 25,75 mg/L diperoleh dari ekstrak daun pangi. Tingkat kematian larva yang tertinggi diperoleh pada perlakuan dengan konsentrasi 50 ppm ekstrak biji fraksi n-heksan sebesar 93,5%, kemudian 86,3% untuk ekstrak daun pangi dan 75,5% untuk ekstrak kulit batang pangi. Ekstrak tumbuhan pangi dengan menggunakan fraksi etanol, ditemukan mengandung alkaloid, saponin, flavonoid, terpenoid, phenol dan tannin. Ekstrak biji pangi dengan menggunakan fraksi n-heksan merupakan insektisida nabati yang paling efektif dalam mengendalikan hama C.binotalis. Hal ini mengindikasikan bahwa insektisida botani dari ekstrak tumbuhan pangi memiliki potensi dalam mengendalikan hama C.binotalis pada tanaman sawi. Evaluasi dan karakterisasi komponen aktif dari ekstrak dan aplikasi di lapangan sangat diperlukan untuk penelitian selanjutnya.

Abstract

The teacher resources development becomes a central issue in public discussion. The plan, implementation, monitoring and evaluation of teacher resource development in Dinas Pendidikan Manado is being provoked and receives attention. The provoking issues play around on how teacher resouces development being planned, implemented, and evaluated. This study takes a qualitative approach and utilizes a case study method. In-depth interviews are the primary data collecting tools, followed by document study techniques/literature and observation. However, monitoring and evaluation success requires adequate implementation quality, appropriate monitoring and evaluation standards, and a special monitoring and evaluation budget. In conclusion, the government should inform and promote the pattern of execution of teacher resource development. That is, more attention and a dedicated budget for the creation of teaching resources are required. The pattern of teacher resource development monitoring and assessment is based on both internal and external stakeholders. The government must state and report the pattern of implementation of teacher resource development. This means that more attention and special budget are needed to create teaching resources. The pattern of monitoring and assessment of teacher resource development is based on internal and external interests. As a result, by using explicit and redundant standards, supervisor quality becomes an important predictor of successful monitoring and assessment.
