Tujuan penelitian ini adalah mengevaluasi program pembelajaran IPA SMP di Kabupaten Bone Bolango berdasarkan Peraturan Menteri Pendidikan dan Kebudayaan Republik Indonesia Nomor 65 Tahun 2013 tentang Standar Proses Pendidikan Dasar dan Menengah. Penelitian ini merupakan penelitian evaluasi dengan model Countenace Stake. Pengumpulan data menggunakan teknik, observasi, wawancara dan dokumentasi. Teknik analisis yang digunakan adalah deskriptif kualitatif. Kesimpulan hasil penelitian sebagai berikut: (1) perencanaan pembelajaran IPA termasuk kategori cukup (68%), ditemukan belum adanya kesesuaian antara RPP dengan standar proses pembelajaran; (2) pelaksanaan pembelajaran IPA termasuk kategori cukup (57%), belum adanya kesesuaian antara pelaksanaan pembelajaran dengan standar proses pelaksanan pembelajaran; dan (3) hasil belajar peserta didik belum memenuhi Kriteria Ketuntasan Minimal (KKM) dengan aktualitas ketercapaian 65% kategori cukup. 4) terdapat contingency antara perencanaan, pelaksanaan dengan hasil belajar IPA, yang perencanaan pembelajaran dengan kategori yang cukup menyebabkan guru melaksanakan pembelajaran belum sesuai standar proses sehingga hasil belajar peserta didik belum memenuhi KKM.

This study used Stake’s Countanance evaluation model. The data were collected using observation, interview and documentation techniques. The conclusion was: (1) the planning of science learning was categorized fair (68%), it was found that lesson plan was not in accordance with the learning processing standard. (2) The implementation of science learning was categorized fair (57%), that unconformitted with learning processing implementation standard. (3) Student learning outcomes have not met the completeness of minimum criteria (KKM) that categorized enough (65%) and (4) There were the contingency of planing learning proces and outcome.

Audiovisual media is a set of tools that can project moving images and sound. This study aims to produce audio-visual learning media that integrates character education in chemistry learning to facilitate conceptual change and strengthen student character. This research is development research which includes three stages, namely preliminary studies, development, and validation, as well as testing and implementation to produce valid, practical, and effective audio-visual learning media. The validation was carried out by three experts through Focus Group Discussion. The audio-visual media and learning tools developed were tested on state senior high school students 1 Kabila Gorontalo. The research data technique used observation and three-level diagnostic tests. The data analysis used a qualitative descriptive technique. The results obtained are audio-visual learning media developed with validity with very valid categories, practicality with very high categories, and effective in shifting students’ conceptions from misconceptions and not seeing concepts to understanding concepts with high N-Gain. category, which is 0.83. This study concludes that the audiovisual learning media and learning tools developed are of good quality.
This research aims were (1) the support of the policy, (2) the resources, and (3) the implementation of science learning supervision, (4) the performance of secondary science teachers in Gorontalo City. The conclusions that (1) the supervision was based on laws of national regulations, (2) Teachers perception based on their experiences, supervisors and school principals focused on the schools and classroom visit supervision, their characteristics were in accordance with the National Standard, and potentially to be developed. The resources has met the Minimum Service Standard (MSS), (3) the implementation of science supervision has not met the MSS. and (4) teachers performance; best 16%, good 43% and fair 5% and remaining (36%) did not have the willingness to be supervised.

This study aims to develop chitosan bioadsorben from shrimp shell waste that is applied to water samples in unlicensed mining activities in the Bone River of Gorontalo Province. The properties of chitosan were characterized, such as the determination of water content, ash content, solubility test and determination of acetylation degree by using FTIR. Prior to the application of chitosan products into samples in unlicensed mines locations, a qualitative metal mercury test was conducted on the samples using specific reagents for mercury metals, namely HCl, KI, NaOH, and NH3. The result showed that chitosan deacetylation degree was 73.88%, characterization test fulfilled chitosan standard requirement that was ash content 0.4%, water content 6.48% and soluble in acetic acid. Chitosan products from shrimp shell waste can be used as an environmentally friendly bioadsorbent that can reduce the level of mercury metal in the unlicensed mining activities in the Bone River of Gorontalo Province by 54.90%.
This study aims to determine the effect of using the Problem Solving learning model on Self-Confidence and student learning outcomes on the topic of reduction-oxidation. The research design used was Quasi-Experimental Design with Pretest-Posttest Control Group Design. The sample of this study amounted to 58 students, where 29 students in the experimental class and 29 students in the control class. In the experimental class, the Problem Solving learning model was applied while in the control class conventional learning models were applied. Data analysis for hypothesis testing using a separated variant t-test. The results of the data analysis showed that self-confidence at a significant level of 0.05 with dk = 56 was obtained tcount 2,284 > ttable 1,672, then H0 was rejected and H1 was accepted so that there was an effect of the problem-solving learning model on self-confidence. Results of data analysis Learning outcomes show that at a significant level of 0.05 with dk = 56 obtained tcount 7.519 > ttable 1.672.
Penelitian ini bertujuan untuk mendeskripsikan kesulitan pemahaman larutan penyangga siswa di Gorontalo, yang diukur dalam 5 aspek,yaitu: pengertian, prinsip kerja, pH dan pOH, pH asam basa,dan fungsi penyangga dalam tubuh manusia. Penelitian kuantitatif deskriptif ini dilakukan pada siswa kelas XI (N=215) di Gorontalo. Data dijaring dengan instrumen tiga tingkat. Hasil penelitian ditemukan bahwa aspek pH asam basa (96.5%) paling sulit di pahami siswa, dibandingkan aspek fungsi larutan penyagga dalam tubuh manusia (94.9%), pH dan pOH (89.3%), prinsip kerja (83.7%), pengertian (48.8%). Temuan ini mengindikasikan bahwa siswa belum memahami dengan baik dan benar konsep larutan penyangga. Hasil penelitian ini menjelaskan bahwa diperlukan pembelajaran remedial untuk menyiapkan materi pembelajaran selanjutnya
Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran materi larutan elektrolit dan larutan non elektrolit berbasis model pembelajaran Argument-Driven Inquiry yang valid untuk melatih keterampilan argumentasi ilmiah siswa SMA. Pengembangan perangkat pembelajaran menggunakan model 4D (Four D), yang meliputi tahap pendefinisian (define), perancangan (design), pengembangan (develop), serta tahap penyebaran (dissemination). Namun dalam pelaksanaannya, penelitian ini terbatas hanya sampai pada tahap develope. Instrumen pengumpulan data dalam penelitian ini adalah lembar validasi. Teknik analisis data menggunakan analisis deskriptif kualitatif. Temuan hasil penelitian, yaitu perangkat pembelajaran yang dikembangkan meliputi buku siswa, RPP, LKPD, video pembelajaran dan instrumen tes keterampilan argumentasi ilmiah telah memiliki validitas dengan kategori sangat valid; Hasil penelitian telah menunjukkan bahwa perangkat pembelajaran materi larutan elektrolit dan non elektrolit berbasis model pembelajaran Argument-Driven Inquiry telah memenuhi syarat valid dari segi isi dan konstruk.
