Sampel yang digunakan adalah seluruh siswa yang mengikuti ekstrakurikuler pencak silat. Pemilihan sampel menggunakan teknik sampling jenuh dengan jumlah sampel 25 siswa. Angket yang digunakan dalam artikel ini diadopsi dari penelitian terdahulu yang sudah diuji validitas dan reliabilitasnya. Kuesioner ini terdiri dari 2 sub motivasi yaitu motivasi intrinsik dan motivasi ekstrinsik. Teknik analisis data menggunakan presentase dengan di bantu aplikasi SPSS version 25. Hasil dari penelitian menunjukkan bahwa motivasi intrinsik dalam kategori ”Baik” dengan nilai sebesar 79,73%, sedangkan motivasi ekstrinsik dalam kategori “Cukup” dengan nilai sebesar 69,81%, dan nilai rata-rata dalam kategori “Cukup” dengan nilai sebesar 74,77%. Sehingga dapat disimpulkan bahwa tingkat motivasi siswa yang mengikuti ekstrakurikuler pencak silat di SMA Negeri 1 Patianrowo selama masa pandemi Covid-19 dapat dikategorikan “Cukup”. Kata Kunci: motivasi; ekstrakurikuler; pencak silat. Abstract During Covid-19 pandemic, Pencak Silat extracurricular activities could not be carried out properly which affected the level of student motivation. The purpose of this study was to determine level of motivation students in taking Pencak Silat extracurricular at Senior High School 1 Patianrowo during Covid -19 pandemic. This research is a descriptive quantitative using the survey method. The scoring rules use a Likert scale. The data was collected online by distributing questionnaires using the google form which were distributed via whatsapp group. The sample used is students who take Pencak Silat extracurricular. The sample selection used a saturated sampling technique with sample of 25 students. The questionnaire used in this article was adopted from previous research that had been tested for validity and reliability. This questionnaire consists of 2 sub motivations, namely intrinsic motivation and extrinsic motivation. The data analysis technique used a percentage with the help of the SPSS version 25 application. The results of the study showed that intrinsic motivation was "Good" category with a value of 79.73%, while extrinsic motivation was "Enough" category with a value of 69.81%, and the average value in "Enough" category with a value of 74.77%. So it can be concluded that the level of motivation of students who take Pencak Silat extracurricular at Senior High School 1 Patianrowo during Covid-19 pandemic can be categorized as "Enough".

Kaji Eksperimental Kehilangan Panas pada Dinding Ruang Bakar Fluidisasi Berbahan Bakar Biomassa

Biomass has several advantages, especially as it is renewable in nature. The low energy content owned by biomass requires the use of effective techniques, such as gasification.  This research was to determine the rate of heat transfer that occurs in the burning of fuel in the combustion chamber fluidized types. The benefit of this research is to identify the heat loss in biomass combustion system. The fuels used in this study are wood-planed chips, branches of dry wood and areca nut husk. The size of fuel was 2 to 3 mm. The fuel was weighed to 2 kgs for one testing/biomass. The combustion duration was 50 seconds. The heat loss in biomass combustors with wood-planed chips occurred in 30 seconds at Tf 724oC and TW 203 oC, the heat loss was 26813.33 W/m. The heat loss in the combustion chamber with biomass wood-planed chips in 15 seconds at Tf-average 334 oC and Tw 44 oC, the heat loss was 2947.03 W/m. The heat loss in biomass combustors with branches of dry wood in 30 seconds at Tf 713 oC and Tw 201 oC, the heat loss was 26350.15 W/m. The heat loss in the combustion chamber with branches of dry wood biomass in 20 seconds at Tf-average 286 oC and Tw 42 oC, the heat loss was 2479.57 W/m. The heat loss in biomass combustors with areca nut husk occurred in 20 seconds at Tf 515 oC and Tw 137 oC, the heat loss was 19453.82 W/m. The heat loss in the combustion chamber with areca nut husk biomass occurred in 15 seconds at Tf- average 118 oC and Tw 39 oC, the heat loss was 802.81 W/m

Strategi Scaffolding Berbasis Multirepresentasi untuk Mengatasi Kesulitan Pemahaman Konseptual Siswa dalam Operasi Pecahan di SMP

This research aims to overcome the students' difficulties of conceptual understanding of mathematics by using scaffolding strategy based-multi representation in addition and substraction of fractions at seventh grade students of SMPN 13 school year 2014/2015. This research method used is descriptive analysis which is oriented on students problem solving in learning addition and substraction of fractions. The subjects of this research are 3 students at grade VII F of SMPN 13 Pontianak that represent in each ZPD (high, medium, low). The result of data analysis showedthatafterthe implementation ofscaffoldingstrategiesbased-multirepresentation, eachresearch subjectcouldget through theZPDandthe mistakesmade incompletingthe pre-test can beminimized(Viewedfrompost-test)

Kemampuan Representasi Matematis Siswa melalui Pembelajaran Berbasis Masalah di Sekolah Menengah Atas

The purposes of this study are: to assess the students' mathematical representation in solving problems after being given a problem-based learning model; to assess the students' mathematical representation associated with the conceptual understanding; and to assess the students' mathematical representation associated with the procedural understanding. This is a quantitative research. The approach employed in this study is the equivalent time samples design. The population of this study is all twelve grade students of SMA Santu Petrus Pontianak in the academic year 2014/2015. The randomly selected samples are class XII-IA3 students. The data obtained from both pretest and post-test were statistically and descriptively analyzed. The results are: the students' mathematical representation has increased significantly after receiving the problem-based learning model, the students are able to organize their knowledge to perform translations one representation form to the other representation form. The association between the mathematical representation and the conceptual understanding and the procedural understanding after the problem-based learning is considered fair
