Abstract

This research aims in descripting Science Process Competence (KPS) and student scientific behavior at SMP I Atap Pulau Tunda, Tirtayasa Region, Serang Regency.  This research was an introduction research  /observation to determine the study method or model  that can elevate KPS and student scientific attitude.   The research sample was students of SMP I Atap Pulau Tunda selected by purposive sampling.   Data was collected from KPS test, observation sheets of students scientific behavior during learning process,  interview sheets, and learning rank by the teacher.  This research result shows that the Science Process Competence and the scientific behavior of the students were still low.  Some of the reasons were the learning process was still ‘teacher centered’,  the teacher knowledge related to KPS and the scientific behavior  was still not adequate,  and the training experience was still not maximum.  Trainings given to teacher related to learning method and model, seminars about KPS and scientific behavior,  and facilitation given by of the headmaster and the government  are hopefully can elevate Science Process Competence and the scientific behavior at SMP I Atap Pulau Tunda.  Key Words: Science Process Competence, Scientific Behavior, and Science

Abstract

Masalah korosi pada pipa di kilang minyak sangat bervariasi tergantung padajenis minyak mentah yang di proses, atau karena kondisi lingkungan. Salah suatucara untuk mencegah agar pipa tidak terjadi korosi yaitu dengan sistem proteksikatodik untuk mengendalikan korosi pada permukaan logam dengan menjadikanpermukaan logam sebagai katode dari sel elektrokimia. Dari data pengamatanpanjang pipa adalah 28.000 m dan diameter pipa 8 inch dengan anoda yangdipakai adalah anoda magnesium 32 lbs. Hasil dari perhitungan untuk proteksikatodik adalah luas permukaan pipa sebesar 19261,074 m2, total kebutuhan arusproteksi 10,593 A, tahanan anoda yang dipasang horizontal 0,882 ohm, keluaranarus anoda per batang 0,567 A, total kebutuhan anoda 122 batang dengan umuranoda 26,349 tahun. Dari hasil evaluasi menunjukan bahwa pipa keseluruhan yangterproteksi dalam kondisi baik.Kata Kunci : Anoda, Korosi, Permukaan logam, Pipa, Proteksi Katodik.

Abstract

Cross Section Accumulative Roll Bonding (C-ARB) adalah proses perpaduan dua material dengan cara penggilingan arah sejajar dan arah melintang. Material dipanaskan dengan suhu 350oC selama 90 menit. Proses C – ARB menghasilkan area pada material yaitu Hot Region (area panas) area material yang pertama masuk mesin roll dan Cold Region (area dingin) area material yang terakhir masuk mesin roll, menggunakan aluminium 5052. Penelitian dilakukan untuk mengetahui perbedaan kekuatan antar Interface dari Hot Region dan Cold Region, dengan siklus pengerollan 3x dan 10x, dan bahan penguat Alumina Al2O3 serat sebagai Reinforce, dan tanpa alumina sebagai perbandingan. Nilai kekerasan dan kekuatan tarik meningkat seiring banyaknya jumlah penggilingan karena semakin banyaknya penggilingan, kedua materialnya semakin rapat sehingga material menempel dengan baik, Hot Region memiliki nilai yang lebih kuat daripada Cold Region, karena Cold Region kurang terdifusi dengan baik

Abstract

The implementation of new applications to support organizational work, integral to the adoption of SPBE in Indonesia, often encounters a lack of readiness among management officials. This challenge extends to the village level, the lowest tier of government, where the introduction of the E-office as a digital-based administrative service represents both a breakthrough and a formidable hurdle for village officials unfamiliar with information technology. This study aims to assess the competence of the village officials in facilitating the operationalization of the E-office and proposes strategies to enhance their digital service proficiency, focusing on Mekarwangi Village in Tomo District, Sumedang Regency. Employing a descriptive qualitative research approach, data collection involves interviews, observations, and documentation, with data triangulation as the analytical technique. The study reveals that the competence of the Mekarwangi Village officials is currently minimal, primarily due to a lack of adequate education, training, and insufficient support from local or central governments in providing facilities for enhancing the officials' competence in managing village potential data—a critical aspect of E-office operations. In response, the Sumedang government is actively addressing this issue by regularly conducting training and socialization programs on online-based services, specifically the village E-office, for village officials and communities. Efforts have been made to improve the quality and quantity of supporting infrastructure, such as internet network capabilities and the availability of laptops. To foster competitiveness among villages, the government is also instituting awards for those successfully implementing the E-office, accompanied by guidance for villages facing challenges in its optimal operation.
