ANALISIS POTENSI ANGIN DI KECAMATAN JATEN KABUPATEN KARANGANYAR BERBASIS INTERNET OF THINGS (IoT)
Get PDFPenelitian ini bertujuan untuk mengidentifikasi rekomendasi turbin angin yang sesuai untuk pengukuran berdasarkan potensi angin di Kabupaten Jaten. Penelitian ini menggunakan metode eksperimen. Sumber data untuk penelitian ini meliputi pengukuran kecepatan dan arah angin yang diperoleh menggunakan mikrokontroler berbasis IoT. Purposive sampling digunakan untuk mengumpulkan sampel. Alat yang digunakan untuk pengambilan data terdiri dari anemometer untuk mengukur kecepatan angin dan wind vane untuk menentukan arah angin. Data dianalisis secara deskriptif dan kuantitatif. Hasil kajian menunjukkan kecepatan angin rata-rata tertinggi teramati pada ketinggian 10 meter Di Kabupaten Jaten kecepatan angin rata-rata 0,47 m/s, dengan kecepatan tertinggi 3,38 m/s. Arah angin dominan bertiup dari Tenggara ke Barat. Potensi angin di daerah ini tidak cukup tinggi untuk dimanfaatkan secara efektif sebagai sumber energi angin yang signifikan karena besarnya yang rendah. Dalam konteks Kabupaten Jaten, kincir angin Savonius vertikal direkomendasikan untuk memanfaatkan kecepatan angin rendah. Jenis turbin Savonius yang dapat digunakan seperti turbin Savonius tipe Helical 2 bilah dengan end plate memiliki kecepatan potong 1,906 m/s dan turbin Savonius tipe S 2 bilah dengan penambahan 4 sirip memiliki kecepatan potong 1,8 m/s
Analisis Persepsi Mahasiswa Terhadap Ketidakjujuran Akademik : Studi Kasus di Fakultas Teknik UNS
Get PDFAcademic dishonesty is a deliberate violation of academic rules for personal gain. Academic dishonesty can reduce the reputation of students and universities, as well as dishonest behavior in the world of work, so research is needed regarding engineering students' perceptions of academic dishonesty. This study aims to determine perceptions, experiences, reasons why engineering students commit academic dishonesty, and to determine the influence between perceptions and experiences of witnessing acts of academic dishonesty. The population used in this study were S1 students from the UNS Faculty of Engineering and the samples taken were 97 respondents. The results of the study show that engineering students' perceptions of academic dishonesty are that students know that academic dishonesty is important, can have an impact on damaging moral character, including actions that violate social and religious norms, so that it becomes the student's responsibility, and must be responsible for caring for the integrity of other students. . The experience of engineering students with academic dishonesty is that students have committed dishonesty but support existing policies, often use unauthorized material during exams, work on papers or articles without including references, and ask for help from seniors who have taken exams but rarely submit assignments properly. pay someone else to complete it and rarely miss out on group assignments. Academic dishonesty policies already exist but sanctions and supervision need to be tightened to reduce academic dishonesty. The reason engineering students commit academic dishonesty is because they don't get sanctioned or punished, the attitude of the lecturer, many friends who do this, will make grades better, difficulty working on questions, easy internet access and fear of failure and lack of study time. Most of the respondents committed academic dishonesty due to internal factors. There is a positive and significant influence between perception and experience of witnessing techniques on the experience of committing academic dishonesty. So that when the perception and experience of witnessing gets higher, they will not commit academic dishonesty
