Kajian Integrasi Nilai-Nilai Karakter Islami Peserta Didik dalam Materi Hidrokarbon di Sekolah Menegah Kejuruan

The inculcation of Islamic character values for students is an important thing to be taught to students. One way of planting is to integrate learning material with the values of Islamic characters of students. This research was carried out through exploring the values of Islamic characters in hydrocarbon material taught in vocational high schools. The purpose of this study is to integrate the values of Islamic characters that are reinforced in the hydrocarbon material in schools. This research is a literature study with qualitative descriptive methods using content analysis techniques, analysis with a philosophical approach, analysis with triadic models, and analysis with confirmation models. The results obtained in this study are the study of the integration of hydrocarbon material chemistry lessons and Islamic character values that can be taught to intermediate level students. The results of the integration are as follows (1) The conversion of a less useful item into a more useful item, (2) Preserving nature as the human task as a Khalifah on earth, (3) Utilizing one of the reactions that occur in hydrocarbon compounds in daily life, (4) Utilizing petroleum as an example of a hydrocarbon product that is very beneficial to humans, (5) The benefits of carbon atoms in the carbon cycle, (6) The benefits of hydrocarbons in photosynthesis to increase our gratitude to Allah SWT, (7 ) The benefits of the special carbon atom in the concept of pairing in life, and (8) Grateful for the greatness of God who has created everything in natur

The Effectiveness of Cognitive Conflict-Based Chemistry Learning in Reducing Students' Misconceptions of Acid-Base Materials

A misconception is a problem that is often encountered in the world of education caused by several things, including students' initial prejudices, incompetent teachers, unclear textbooks, different contexts of the student experience, and teaching methods that only contain lectures. This study is intended to answer the problem regarding the effectiveness of cognitive conflict-based chemistry learning in reducing students' misconceptions about acid-base material. This research is quasi-experimental research with One group Pre-test and Post-test Design. The population in this study was all class XI IPA. The sample in this study was class XI IPA I. The instrument used in this study was a student's concept understanding test. The data collection method used is a multiple-choice reasoned test method. Changes in misconceptions were analyzed descriptively and statistically. A descriptive analysis was conducted to see changes in students' concepts. Statistical analysis using the T-test. Based on the research, it was found that the indicators of questions that experienced misconceptions were: Arrhenius acid-base theory (32.05%), Arrhenius acid-base classification (56.40%), Bronsted Lowry theory (43.59%), writing down the acid-base reaction equation according to Bronsted Lowry and Lewis acid-base theory (59.00%), distinguish between Arrhenius, Bronsted Lowry and Lewis acid-base theories (49.00%), the nature of acidic and basic solutions (47.00), degree of acidity/pH (79.00%), determination of strong acid (79.00%), determination of strong base (46.00%), degree of ionization in acid and base determination (46.00%) and application of the concept of pH in pollution (66.00%). Understanding of students' initial conceptions, namely students who are classified as knowing the concept of 23.18%, misconceptions of 53.95%, and not knowing the concept of 22.87%, while the understanding of the final conception of students is students who are classified as knowing concepts of 76, 20%, a misconception of 15.49% and not knowing the concept of 8.31%. Based on these data, it can be concluded that the cognitive conflict learning method is effective in reducing students' misconceptionsAbstract: Miskonsepsi menunjukkan pada suatu konsep yang tidak sesuai dengan pengertian ilmiah. Miskonsepsi merupakan permasalahan yang sering ditemui dalam dunia pendidikan. Berdasarkan hasil observasi di MA Matholi’ul Huda, diketahui bahwa peserta didik mengalami miskonsepsi pada materi asam basa. Miskonsepsi dapat disebabkan oleh beberapa hal diantaranya yaitu prakonsepsi awal peserta didik, pengajar yang kurang kompeten, buku teks yang tidak jelas, konteks pengalaman peserta didik yang berbeda-beda dan cara mengajar hanya berisi ceramah. Studi ini dimaksudkan untuk menjawab permasalahan mengenai efektifitas pembelajaran kimia berbasis konflik kognitif dalam mereduksi miskonsepsi peserta didik pada materi asam basa. Penelitian ini termasuk penelitian kuasi eksperimen dengan desain One group Pre test Post test Design. Populasi dalam penelitian ini adalah semua kelas XI IPA. Sampel dalam penelitian ini adalah kelas XI IPA I. Instrumen yang digunakan dalam penelitian ini yaitu tes pemahaman konsep siswa. Metode pengumpulan data yang digunakan yaitu metode tes berbentuk multiple choice beralasan. Perubahan miskonsepsi dianalisis secara deskriptif dan statistik. Analisis deskriptif dilakukan untuk melihat perubahan konsep siswa. Analisis statistik menggunakan uji T. Berdasarkan penelitian dihasilkan bahwa indikator soal yang mengalami miskonsepsi yaitu: teori asam basa Arrhenius (32,05%), klasifikasi asam basa menurut Arrhenius (56,4%), teori Bronsted Lowry (43,59%), menuliskan persamaan reaksi asam basa menurut Bronsted Lowry dan teori asam basa lewis (59%), membedakan teori asam basa Arrenius, Bronsted Lowry dan Lewis (49%), sifat larutan asam dan basa (47%), derajat keasaman/ pH (79%), penentuan asam kuat (79%), penentuan basa kuat (46%), derajat ionisasi dalam ketetapan asam dan basa (46%) dan aplikasi konsep pH dalam pencemaran (66%). Pemahaman konsepsi awal peserta didik yaitu peserta didik yang tergolong tahu konsep sebesar 23,18%, miskonsepsi sebesar 53,95% dan tidak tahu konsep sebesar 22,87%, sedangkan Pemahaman konsepsi akhir peserta didik yaitu peserta didik yang tergolong tahu konsep sebesar 76,20%, miskonsepsi sebesar 15,49% dan tidak tahu konsep sebesar 8,31%. Berdasarkan data tersebut dapat disimpulkan bahwa metode pembelajaran konflik kognitif efektif dalam mereduksi miskonsepsi siswa. &nbsp

PENINGKATAN PENGETAHUAN DAN EKONOMI MASYARAKAT DESA MELALUI PELATIHAN PEMBUATAN SABUN SUSU LIDAH BUAYA (ALOE VERA)

Abstrak: Kabupaten Boyolali, Jawa Tengah khususnya kecamatan Cepogo merupakan kawasan peternakan susu sapi dan merupakan salah satu produsen susu terbesar di Pulau Jawa. Susu sapi segar memiliki kelemahan yaitu mudah rusak dan daya simpannya cenderung singkat. Mengolah susu sapi segar menjadi suatu produk merupakan salah satu upaya untuk memperlama daya simpan susu sapi. Tujuan dari pengabdian masyarakat ini adalah untuk meningkatkan pengetahuan dan pendapatan masyarakat melalui pengolahan susu sapi menjadi produk sabun susu. Metode yang digunakan meliputi beberapa kegiatan yaitu persiapan internal tim pengabdian, sosialisasi program dan Focus Group Discussion (FGD), pelatihan pembuatan sabun susu, serta monitoring dan evaluasi pelaksanaan. Kegiatan ini diikuti oleh 25 peserta yang merupakan peternak sapi perah. Hasil dari kegiatan ini adalah adanya peningkatan pengetahuan tentang pembuatan sabun susu sebesar 99,2% dan adanya peningkatan pendapatan sebesar Rp. 172.190,00 dari keuntungan menjual sabun susu untuk setiap liternya.Abstract: Boyolali Regency, Central Java, especially the Cepogo sub-district, is a dairy farming area and is one of the largest milk producers on the island of Java.
