Abstract

Penelitian ini bertujuan untuk membuat media pembelajaran alat uji kekentalan minyak pelumas  menggunakan bola baja jatuh bebas. Penelitian ini menggunakan metode Research and Development, yaitu metode penelitian yang digunakan untuk menghasilkan produk tertentu dan menguji keefektifan produk tersebut. Penulis membuat alat pengukur kekentalan minyak pelumas menggunakan bola baja jatuh bebas dengan desain, alat, dan bahan yang sudah dirancang terlebih dahulu, yang nantinya akan digunakan untuk mengukur kekentalan minyak pelumas. Minyak pelumas yang akan diuji adalah minyak pelumas multigrade yang biasa digunakan masyarakat umum dengan SAE 5W-30, 5W-50, 10W-30, 10W-40, 15W-40, 15W-50, 20W-40, dan 20W-50 dari berbagai merk. Hasil penelitian yang melibatkan pakar dan mahasiswa, menunjukkan bahwa alat uji kekentalan minyak pelumas yang layak digunakan sebagai media pembelajaran.

Abstract

Penelitian ini bertujuan untuk mengetahui kelayakan alat peraga sistem power window berbasis pengukuran untuk meningkatkan kompetensi kelistrikan bodi dan keefektifan penggunaaan alat peraga sistem power window berbasis pengukuran terhadap hasil belajar siswa. Penelitian ini dikategorikan dalam penelitian pengembangan dengan model 4D yang terdiri dari Define (pendefinisian masalah), Design (perancangan), Development (pengembangan), dan Dissemination (penyebarluasan produk) dengan menyesuaikan kondisi yang ada di SMK Islam Al- Hikmah Mayong, Jepara. Desain uji coba penelitian ini melalui dua tahap yaitu terdiri dari pengujian internal dan uji coba lapangan dengan menggunakan metode pretest- postest control group design. Berdasarkan penelitian validasi dari ahli media uji kelayakan alat peraga mendapatkan persentase sebesar 84%. Dengan kriteria “sangat layak” dan rata-rata persentase hasil uji materi sebesar 85% dengan kriteria “sangat layak”. Keefektifan penggunaaan alat peraga sistem power window ditunjukkan dengan adanya perbedaan signifikan, dimana kelas kontrol dan eksperimen memiliki perbedaan yang signifikan yaitu t hitung pada kelas kontrol sebesar 9,77 dan t hitung pada kelas eksperimen sebesar 14,20. Sedangkan pada uji gain juga terdapat peningkatan yang signifikan yaitu pada kelas kontrol mendapat skor 0,88 menunjukkan peningkatan kategori sedang, dan kelas eksperimen mendapatkan skor 0,748 menunjukkan peningkatan kategori tinggi. Hal ini menunjukkan bahwa peningkatan hasil belajar pada kelas eksperimen (menggunakan alat peraga) lebih tinggi dibandingkan dengan kelas kontrol yang tanpa menggunakan alat peraga.

Abstract

The implementation of direct regional head elections that have been held several times has given rise to a new phenomenon, namely the emergence of the phenomenon of a single candidate which for the first time appeared in the implementation of the simultaneous regional elections in 2015. This phenomenon eventually gave rise to polemics and debates which could ultimately be resolved through the Constitutional Court's decision which affirmed that regional elections with one pair of single candidates are still carried out with a mechanism of choosing to agree or disagree, which then developed into choosing between blank columns with pictures and blank columns without pictures as an effort to protect the constitutional rights of voters and candidate pairs who have registered. But what is interesting then is the emergence of a follow-up phenomenon in the implementation of the Regional Elections with one pair of candidates, namely the emergence of support groups for blank columns without pictures or empty boxes. The emergence of this group has sparked a new debate regarding whether or not it is permissible for the group to campaign for an empty box victory. This happens because there is expressly no regulation that regulates the rights of the blank column group without pictures to conduct campaigns, both in Law No. 10 of 2016 and in PKPU No. 4 of 2017 concerning campaigns. This phenomenon attracted the author to conduct a research entitled "The Constitutional Rights of the Community Supporting the Blank Column Without Picture in the Single-Candidate Column Pikada According to the 1945 Constitution" by identifying the problem of how the position of the group supporting the blank column without the picture and what rights can be given to the group in the process of electing regional heads which are only attended by one pair of candidates. This study uses a normative-empirical juridical method with an analytical research nature. The data sources used are primary data and secondary data. The data will be analyzed by means of qualitative analysis. The theoretical basis that will be used is the theory of the state of law and the theory of legal certainty. Based on the analysis of the discussion, the author concludes that Law No. 10 of 2016 and PKPU No. 4 of 2017 do not regulate campaign activities that can be carried out by support groups for blank columns without pictures in the implementation of a regional head election. This has ultimately caused a polemic among stakeholders to respond to this phenomenon
