Teachers have an important role in education. To support it, teachers should have good profess sionalism especially in writing articles. In fact, many teachers are not proficient in writing articles because they do not have enough knowledge about it. Teachers need such training for increasing their experience in writing. After that, the progress will be seen. The research method is descriptive quantitative. The data in this research is quantitative data. The type of data is the primary data.         A data collection technique in this study is questionnaires. Data processing techniques used include editing, coding, tabulation, and scoring. Data analysis technique is descriptive analysis percentage. After doing the training, the teachers have more knowledge and interest of writing articles.

Learning process is a fun activity where learners have the freedom to actualize themselves, develop the potential in accordance with the talent and develop it. It demands educators to be creative in creating teaching materials and media. Teaching materials that can be collaborated with the media is a worksheet student of science asissted by education card based on science edutainment. The purpose of this paper is to produce a worksheet student of science asissted by education card based on science edutainment that is valid, practical and effective. The development model used is a Plomp development model consisting of three stages of initial investigation, development and assessment phase. The validity test is at the development stage. Validity test is done through validation sheet. The result of validity test shows the a worksheet student of science asissted by education card based on science edutainment developed in valid category. Then product can be applied in learning and able to overcome all problems.

Students’ worksheet is one of learning media to help students in studying mathematics. The worksheet is based on guided discovery learning. It is aimed to get the students accostumed in inventing mathematics concept, therefore the worksheet can make it easier for the students to understand sequences and series material. Sequences and series is one of the essential materials tought in vocational school since it is often correlated to problem solving. In general, the students in vocational school lack of ability to do problem solving. This research used Plomp educational design research that consist of initial preliminary research, development or prototyping stage and assesment phase. The instrument used in this research was validation sheet of students’ worksheet. The aim of this research was to produce valid, practice and effective worksheet. The result of this research showed that the Guided Discovery Model worksheet on Sequences and Series was valid, practical and effective.

Abstrak – Pencapaian kompetensi peserta didik masih rendah disebabkan oleh beberapa faktor, di antaranya model pembelajaran yang digunakan dan LKPD (Lembar Kerja Peserta Didik) yang digunakan tampilannya masih sederhana. Jenis penelitian adalah quasi eksperimen research dengan rancangan penelitian randomized control group only design. Populasi penelitian adalah peserta didik kelas X. Sampel penelitian menggunakan teknik cluster random sampling. Alat pengumpul data berupa tes tertulis untuk kompetensi pengetahuan dan lembar unjuk kerja untuk kompetensi keterampilan. Teknik analisis data berupa uji-t, serta uji regresi dan korelasi digunakan hanya untuk kelas eksperimen. Hasil penelitian menunjukkan bahwa perhitungan uji-t pada kompetensi pengetahuan dan keterampilan diperoleh masing-masing thitung = 2,07 dan thitung = 2,09. Nilai ini lebih besar dari ttabel = 2,00. Untuk uji regresi dan korelasi pada kompetensi pengetahuan dan keterampilan memberikan pengaruh masing-masing sebesar 50,41% dan 25,77%, sehingga hipotesis kerja diterima pada α = 0,05.Kata kunci: kompetensi, model discovery learning, LKPD, gerak parabola, gerak melingkar

The wind is one of the important parameters in meteorology to determine weather and climate. It can be determined by using two quantity measured, such us speed and direction of wind. Based on the result of measuring will obtain important information that can be used for disaster prevention. For measuring of wind speed, this reserch design a measurement using optocoupler sensor to determine wind speed with change of sensor resistance. The sensor is conected to an electronic circuit and a microcontroller Arduino Uno Rev3 and it is programmed to get the desired results. Based on data analysis, there are two result of research namely performance and design specifications. The instrument consists of two parts; the electronic circuits and mechanical parts making up the system of measuring instruments of wind speed. Based on the results conducted, the accuracy of this measuring instrument is 91.39% with 3.22% error percentage and the accuracy of the instrument was 98.9% with 1:11% relative error percentage.Key words: sensor optocoupler, microcontroler arduino
