The purpose of this study was to analyze the enhancement of the middle school student problem solving skill through implementation of Project Based Learning (PjBL) model in integrated science learning Connected type. This research used quasi-experiment method with the static group pretest-posttest design. The subject of the research was the students of first grade in Ambon with total number of participants were 42 by using simple random sampling. Data was collected through problem solving skill test and questionnaire response of students about implementation of PjBL model. The technique of analyzing data used normality and homogenous test, N-gain test and t-test were tested by IBM SPSS Statistics 22. The result of this study showed that enhancement student’s problem solving skill showed by N-gain problem solving skill in experiment class is 0,73 (high) and N-gain problem solving skill in control class is 0,63 (moderate). Results of t-test value of problem solving skill got Sig.(t-tailed) 0.000 α, show that PjBL model can help the students to enhance problem solving skill better than the used of traditional model. Students give positive response to the PjBL model in integrated science learning type Connected.Penelitian ini bertujuan untuk menganalisis peningkatan keterampilan pemecahan masalah siswa SMP/MTs melalui penerapan model pembelajaran Project Based Learning (PjBL) dalam pembelajaran IPA Terpadu tipe Connected. Penelitian ini menggunakan metode eksperimen semu dengan desain the static group pretest- posttest. Sejumlah siswa kelas VII (N = 42) di Kota Ambon terlibat sebagai subjek penelitian yang diambil dengan teknik simple random sampling. Pengumpulan data dilakukan melalui tes keterampilan pemecahan masalah dan angket tanggapan siswa. Teknik pengolahan data melalui uji normalitas dan homogenitas, perhitungan N-gain, dan uji-t dengan bantuan program IBM SPSS Statistics 22. Hasil analisis data menunjukkan bahwa peningkatan keterampilan pemecahan masalah ditunjukkan oleh N-gain kelas eksperimen 0,73 (tinggi) sedangkan N-gain kelas kontrol 0,63 (sedang). hasil uji t pada data nilai N-gain keterampilan pemecahan masalah, diperoleh nilai signifikansi Sig. (t-tailed) 0.000 yang menunjukkan hasil yang lebih kecil dari 0,050 yang berarti H0 ditolak dan H1 diterima. Oleh karena itu, pada taraf kepercayaan 95% (α = 5%) diperoleh kesimpulan bahwa model pembelajaran PjBL lebih baik dalam meningkatkan keterampilan pemecahan masalah siswa dibandingkan dengan pembelajaran yang tidak menggunakan model PjBL.

This study aims to determine the effect of discovery learning model on cognitive learning outcomes of class VII students on heat material at MTs Al-Anshor Ambon. The data collection instruments used were tests and observation sheets. The population in this study was class VII MTs Al - Anshor Ambon academic year 2021/2022 which consisted of 2 classes with a total of 19 students. Based on the hypothesis test of the discovery learning model on students' cognitive learning outcomes, the significance value is smaller than the value of , meaning that the H1 hypothesis is accepted. In student learning outcomes which were analyzed using descriptive and inferential statistics, the average value of the experimental class was 100 and the control class was 80 with a standard deviation of 13.31. The results of hypothesis testing using t-test obtained tcount value of 2.616 and at a significant level 0.05 with dk = 17 obtained ttable = 1.740 thus tcount > ttable¬ then H1 is accepted H0 is rejected. This means that there is a significant effect of discovery learning model on cognitive learning outcomes of class VII students on heat material at MTs Al-Anshor Ambon.

Chemistry is a branch of science closely related to daily life. Ethnoscience cannot be separated from science, especially in the study of chemistry. The tradition of distilling eucalyptus oil (Melaleuca cajuputi) on Buru Island has been carried out traditionally for generations. This research aims to analyze and reconstruct the indigenous knowledge of the community in the eucalyptus oil distillation process into scientific knowledge that can be used as a source for learning chemistry. This research used a qualitative approach based on ethnoscience with interview, observation, and documentation methods. Data analysis employs the Miles-Huberman model, which consists of data reduction, data presentation, conclusion drawing, and verification. The results of the research showed that the eucalyptus oil distillation process can be explored in science materials or concepts related to separation techniques, differences in density, phase changes, and substance pressure. The ethnoscience study results indicated the potential of ethnoscience to be applied in chemistry education.
