emahaman mendalam terhadap kriteria kredibilitas, seperti obyektivitas, ketidakberpihakan, dan penerapan metodologi ilmiah. Metode penelitian kualitatif pustaka digunakan untuk menganalisis literatur yang relevan, membuka wawasan tentang kontribusi saksi ahli dalam peradilan pidana. Dalam konteks etika, saksi ahli diharapkan untuk menjaga obyektivitas dan independensi, tanpa kecenderungan pada kepentingan tertentu. Kesadaran terhadap etika profesi dan pengawasan terhadap pemilihan saksi ahli menjadi faktor kunci untuk memastikan integritas peradilan. Analisis mendalam terhadap dampak kesaksian yang tidak sesuai etika dan standar ilmiah menyoroti implikasi praktis dan teoretis dari peran saksi ahli. Penelitian ini juga membahas dampak saksi ahli terhadap kebijakan dan regulasi peradilan pidana, menyoroti perlindungan integritas peradilan dan perlunya penyesuaian kebijakan. Implikasi praktis dan teoretis dari peran saksi ahli dalam sistem peradilan pidana menunjukkan dinamika kompleks antara aspek hukum dan etika. Kesimpulannya, pemahaman yang mendalam terhadap peran saksi ahli dari perspektif hukum dan etika mendukung pencapaian keadilan dalam sistem peradilan pidana. Kontribusi saksi ahli yang dilandasi oleh integritas dan etika tinggi menjadi elemen utama dalam memelihara kepercayaan masyarakat pada keadilan dan integritas peradilan pidana.

Abstract:This study discusses the design and construction of a corn sheller with a capacity of 80 kg/hour using an internal combustion engine . A corn sheller is a machine that functions to shell corn to separate the corn kernels…
from the corn cobs. In Indonesia, corn is available in abundance in rural areas, especially during the harvest season. In the production process, generally, during the shelling process, many farmers still use the shelling method by hand or using simple tools, which takes quite a long time. The reason people still use the shelling method by hand or using tools is because the price of the machine is too expensive and they are not even aware of the existence of a corn shelling machine. This corn shelling machine with a 5.5 HP internal combustion engine is a tool designed to speed up and simplify the corn shelling process efficiently and produce a fairly large production capacity of 80 kg / hour. To extend the service life of this corn shelling machine, maintenance and cleanliness should be carried out so that the machine can operate optimally without problems. Safety also needs to be considered to avoid unexpected work accidents.

dapat dia lakukan. Namun, karena kurangnya dorongan, keinginan, dan motivasi dari peserta didik sendiri, minat membaca terus meningkat, terutama di kalangan siswa yang masih duduk di bangku sekolah dasar. Hal ini disebabkan oleh karena kurangnya peranan orangtua dan guru dalam menerapkan minat membaca pada peserta didik. Penelitian ini bertujuan untuk mengetahui peran orang tua dalam meningkatkan minat baca pada anak. Jenis penelitian yang dilakukan peneliti adalah metodologi kualitatif sebagai prosedur penelitian yang mengahasilkan data deskriptif berupa kata-kata tertulis atau lisan dari orang- orang atau perilaku yang diamati. studi kasus yang bersifat deskriptif.Teknik pengumpulan data pada penelitian ini meliputi wawancara, observasi.Teknik analisis data dalam penelitian ini menggunakan model Miles, Huberman dan Sadana meliputi pengumpulan data, kondensasi data, display data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa peran orang tua terhadap anak-anaknya berbeda-beda dan mempengaruhi minat belajar dan membaca anak. Orang tua yang kurang memperhatikan waktu belajar anaknya menyebabkan minat belajar dan membaca anak juga kurang. sedangkan orang tua yang lebih memperhatikan dan mengontrol waktu belajar anaknya maka anak tersebut memiliki minat belajar dan membaca lebih besar dari anak lainnya. Sehingga peran orang tua juga sangat penting untuk mempengaruhi minat membaca peserta didik. Berdasarkan hasil penelitian tentang peran orang tua dalam meningkatkan minat membaca di Desa Perumas Simalingkar Dusun Lada maka peneliti mengambil kesimpulan yaitu Orang tua di rumah membiasakan anaknya belajar dan membaca dengan membuatkan jadwal dan kontrol serta pengawasan langsung dari orang tua. Orang tua juga dapat berperan meningkatkan minat baca pada anak dengan cara membuat perpustakaan kecil dirumah yang berisi buku cerita, pelajaran, komik dan apapun yang digemari anak serta pentingnya memotivasi anak untuk membuat minat baca anak meningkat.

tics teachers in Ghana's Ashanti Region regard as the most influential in influencing their confidence in their abilities to teach their subject. It was requested that 154 senior high school teachers from 20 different senior high schools reply to a questionnaire containing 12 items. According to the results of an independent sample t-test, male teachers have significantly stronger self-efficacy views than their female colleagues. Again, the results of a one-way analysis of variance (ANOVA) test reveal that there was no statistically significant difference between the means of the five groups of teacher teaching experience in terms of teacher efficacy. Teachers should take part in ongoing professional development activities to make sure they are still good at their jobs.
