Abstract

The subjects of this research are waste of pinepple’s peel (Ananas Comosus (L) Merr) and local beef that were obtained from Jrakah traditional market, Ngaliyan-Semarang. The data technique analysis of this research is descriptive statistics. The result of this research shows that there is influence of waste of pineapple’s peel as source of bromelain enzyme to increase meat quality, especially tenderness. The higher the bromelain enzyme concentration used, the  more tender the meat, although will be may increase the score of cooking loss. The meat that is submerged with the highest concentration (40%) of bromelain enzyme solution has score of 0.6662 and 45% of cooking loss. The organoleptic quality identification of meat that is submerged with bromelain enzyme solution, generally is better than the control meat. The meat that is submerged with bromelain enzyme solution gives better appearance, flavor, juiceness, and tenderness than the control meat. © 2015 JNSMR UIN Walisongo. All rights reserved.

Abstract

The research aims to: analyze student's misconception on solubility and solubility product constant (Ksp) using the instrument of three-tier multiple choice test, and know the percentage of student's misconception. The research method used a mixed method with sequential explanatory strategy. Data collection technique was collected by diagnostic test using 20 questions of three-tier multiple choice that was completed by reasons and level of confidence, then the result of student's answer was analyzed. The result of the research shows that the diagnostic instrument test of three-tier multiple choice has fulfilled valid and reliable criteria. The implementation diagnostic instrument of three-tier multiple choice  shows misconception percentage of solubility material was 5,272%, solubility product constant (Ksp) was 7,339%, the effect of same ions was 2,025%, the effect of pH on solubility was 4,597%, and sub-material of Ksp and the reaction process of sedimentation was 9,870%.

Abstract

This study aims to determine the effectiveness of the application of the TAPPS model assisted by Question Cards on student learning outcomes and activeness. The population in this study were students of class XI-IPA at SMA Negeri 1 Karanganyar, Demak. Determination of the sample using the purposive sampling system obtained two classes to be sampled, namely class XI-IPA2 as the experimental class which was treated using the TAPPS model assisted with Question Cards while XI-IPA1 as the control group which received treatment using the lecture method assisted by Question Cards. The research data were obtained by means of test and observation. Based on the results of the study, the average value for the experimental group was 83.16 while for the control group an average value of 77 was obtained.Based on the analysis based on the learning outcomes, the experimental group's results were better than the control group as indicated by the tcount (3.59)> ttable (1.98). As for student activeness, it was found that the experimental group was better than the control group with the results of data analysis tcount (4.23)> ttable (1.98). solubility subject matter and solubility product, with the magnitude of the influence on student learning outcomes is 20.48% and the magnitude of the influence on student activeness is 27.04%.

Abstract

Penelitian ini penting dilakukan karena sikap mahasiswa ketika pembelajaran dilakukan secara daring akan memberikan outcome yang berbeda. Tujuan dari penelitian ini adalah untuk mengetahui profil sikap mahasiswa kimia dan pendidikan kimia dalam mempelajari mata kuliah kimia dasar yang dilakukan secara daring. Ini merupakan penelitian kualitatif dimana data dihasilkan dari penyebaran Kuesioner yang diberikan kepada mahasiswa kimia dan pendidikan kimia, kemudian dilanjutkan dengan wawancara lebih lanjut terhadap subjek penelitian Data yang dihasilkan kemudian dianalisis dengan menghitung skor rata-rata dari setiap item pertanyaan yang kemudian diprosentasikan. Hasil penelitian menunjukkan bahwa sikap mahasiswa kimia dan pendidikan kimia di UIN Walisongo Semarang masuk dalam kategori sangat baik. Pada indikator terkait dengan praktikum, mahasiswa cenderung kurang senang dengan praktikum yang dilakukan secara virtual melalui video. Sedangkan pada indikator terkait kebermanfaatan dan pentingnya mempelajari mata kuliah dasar menghasilkan skor tertinggi dari keempat indikator yang ada.

Abstract

Salah satu tantangan di bidang pendidikan Indonesia adalah meningkatkan literasi sains siswa. Berdasarkan data PISA tahun 2018, Indonesia mengalami penurunan peringkat. Tawaran solusi yang bisa digunakan untuk meningkatkan literasi sains adalah penggunaan model pembelajaran Guided Note Taking (GNT) yang terintegrasi Unity of Science (UoS). Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran GNT terintegrasi UoS terhadap literasi sains siswa pada materi asam dan basa. Metode penelitian ini adalah kuantitatif eksperimen dengan jenis quasi experiment. Sampel yang digunakan adalah kelas XI MIPA 1 dan 2 SMA N 2 Semarang. Hasil data yang diperoleh dinyatakan data yang normal dan homogen yang kemudian digunakan Uji t menunjukkan 0,811 pada pre test dan post test 0,02. Hasil uji N-gain menunjukkan skor kelas eksperimen 0,472 dan kelas kontrol 0,194. Berdasarkan analisis data tersebut diambil kesimpulan bahwa kedua kelas setelah diberikan perlakuan memang mengalami peningkatan, tetapi peningkatan pada kelas eksperimen lebih tinggi daripada kelas kontrol.

Abstract

Pendidikan karakter memiliki peran penting dalam mengembangkan kemampuan peserta didik, salah satunya pendidikan karakter yang harus ditanamkan pada peserta didik adalah karakter percaya dengan kemampuan diri sendiri atau self-efficacy. Namun, tingkat self-efficacy peserta didik masih tergolong rendah yang disebabkan oleh beberapa faktor. Tujuan penelitian ini adalah untuk mengembangkan LKPD berbasis Problem Based Learning untuk menumbuhkan self-efficacy pada materi asam basa. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan 4-D yang diadaptasi dari Thiagarajan kemudian dimodifikasi menjadi 3-D. Subjek penelitian ini adalah peserta didik kelas XI MA Darun Najah. Instrumen pengumpulan data yang digunakan berupa angket kebutuhan peserta didik, angket validasi ahli, angket praktikalitas guru, angket respon peserta didik, dan angket self-efficacy. Nilai validasi dari ahli materi dan ahli media masing-masing adalah 0,88 dan 0,80 dengan kriteria sangat valid dan valid. Uji praktikalitas diperoleh hasil sebesar 79% dengan kriteria praktis. Hasil angket respon peserta didik sebesar 82,4% dengan kategori sangat praktis. Peningkatan self-efficacy peserta didik sebesar 0,32 dengan kriteria sedang. Tingkat self-efficacy peserta didik berdasarkan perhitungan angket menunjukkan 16% peserta didik mempunyai self-efficacy tinggi, 34% peserta didik pada kategori sedang, dan 50% peserta didik pada kategori rendah.

Abstract

This research aims to analyze the misconceptions that occur in chemical bonding materials and offer remediation processes. This type of research was library research with data taken from library materials or information. There were 32 scientific journals related to the research topic, then grouped within the last five years, and four scientific journals were produced that discussed misconceptions in chemical bonding material and four scientific journals that discussed the process of remediation of misconceptions in chemical bonding material. Based on the results of the review, misconceptions about chemistry occur in almost every sub-topic. The offer to remediate misconceptions that occur in this material is the ECIRR learning model, cognitive conflict strategy, and conceptual change strategy.
