Abstract

Risk analysis aims to prevent the incompatibility of a system used in the testing process including the Boiler system. At the Labuan 2 Steam Power Plant (PLTU) 2, the Boiler component was declared "very often" to have a pipe leak. Failure Mode And Effect Analysis (FMEA) is a method used to analyze the risk of failure. This method is represented by calculating the value of RPN (Risk Priority Number) obtained from the results of the multiplication of S (severty), O (occurrence), and D (detection). The highest analysis results are shown at 480 (in the steam drum component in the form of abnormal steam and water level failure). The cause is human error. Next three levels below are (1) Economizer component, which is 360 causes of combustion side ash erosion, material lifetime, and economizer tube fibration; (2) super heater tube and re-heater tube components which are 320 due to Corrosion, Overheat Flyash erosion, Sub blower erosion, Welding error; and (3) Walltube which is 320 causes of overheating and sub blower erosion. The recommendation for the analysis of FMEA testing to predict mantenance is done by applying remaining life assessment after 8,000 hours / operational.

Abstract

Tujuan perancangan panel peraga kelistrikan luar mobil ini adalah  untuk  meningkatkan kompetensi berfikir  kritis mahasiswa. Media pembelajaran yang telah dirancang selanjutnya dilakukan pengujian untuk didapatkan validasi sesuai dengan karakteristik media meliputi aspek: kriteria pendidikan, tampilan program, dan kualitas teknis. Validasi ini di bagi menjadi dua bagian yaitu validasi ahli dan validasi pengguna. Validasi ahli terdiri dari validasi oleh ahli media yang dilakukan oleh dosen di bidang pendidikan kejuruan. Analisis terhadap pakar ahli media dengan kriteria tampilan program dan kualitas teknis memiliki rerata “baik”, secara  tampilan dan kualitas teknis sudah baik. Setelah dilakukan revisi, maka selanjutnya analisis isi materi dengan kriteria pendidikan, tampilan program, dan kualitas teknis sesuai dengan kebutuhan uji. Pada bidang materi hasil rerata yang didapatkan “Sangat Baik”. Hasil uji pengguna diperoleh hasil “Sangat Baik” dilihat dari segi pendidikan, tampilan program, dan kualitas teknis. Pernyataan tersebut diperkuat dengan sikap dan tanggapan mahasiswa yang dapat disimpulkan bahwa media ini dapat dniyatakan “Sangat Baik”. Hal tersebut menunjukkan bahwa siswa sangat tertarik dengan media yang bersifat baru dan menyenangkan, serta dapat memotivasi belajar mahasiswa.

Abstract

The 2013 curriculum uses a classroom-based assessment. The curriculum contains various supporters, one of which is an assessment. Assessment by teachers is used to measure the achievement of learning objectives. But in the real world, a teacher has difficulty in developing assessment planning, assessment implementation, and processing of assessment result, and teacher has not analyzed comprehensively about validity and reliability in question, and analysis of evaluation instrument conducted by the teacher is only limited to analyze difficulty level. Thus, the problem that is made to know the cognitive level of students has not known the quality. The objectives of this study were (1) to know the reliability of cognitive assessment instruments developed, (2) to know the level of difficulty, (3) to know the differentiating power, and (4) to know the effectiveness of the cultivators. The method used in this research is research and development (R & D) developed by Borg & Gall. Data analysis technique that is done is instrument validation test with construct validity through judgment expert, reliability test using ITEMAN with formula CR-20. This study resulted in (1) the reliability of the question items of 0.740, (2) the degree of difficulty there are three levels, namely difficult 23%, medium 70%, and easy 7%, (3) distinguishing power on the grain matter analysis resulted in 20%, 7% of the questions are sufficient, 60% is good, and 13% are very good, and (4) the effectiveness of the deception is 82% working and 18% not working.

Abstract

Listrik merupakan sesuatu yang sangat dibutuhkan, karena itu perlu adanya pembangkit untuk mengkonversi energi mekanis menjadi energi listrik, salah satunya adalah turbin uap. Tujuan dilakukan penelitian untuk mengetahui sistem turbin uap, mengetahui permasalahan yang terjadi pada performa low pressure turbin uap serta dapat membandingkan performa low pressure turbin uap sebelum dan setetah blade dipotong. Teknik pengumpulan data telah dilakukan dengan berbagai metode untuk mendapatkan informasi penelitian. Metode observasi dilakukan dengan  mengamati kegiatan yang di lakukan di industri. Selain itu dilakukannya wawancara dengan mengajukan pertanyaan secara langsung ataupun tidak langsung kepada 8 Narasumber yang bekerja di PT. Indonesia Power UJP PLTU Banten 2 Labuan serta pengumpulan dokumen-dokumen tertentu sebagai dokumentasi dan studi pustaka dengan mengumpulkan informasi dari buku, data manual book perusahaan, atau internet. Adapun metode kuantitatif deskriptif penulis melakukan penelitian dengan memperoleh data berupa angka-angka.Kesimpulan penelitian ini yaitu turbin menggunakan sistem tertutup, terdapat penurunan daya di low pressure turbine akibat kandungan uap yang kurang baik karena mengandung silika sehingga dilakukan pemotongan blade pada stage ke-4. Pemotongan blade tersebut karenan adanya crack dan sangat berpengaruh terhadap nilai performa low pressure turbine. Nilai tersebut menjadi turun sebesar 20 MW dari nilai sebelumnya.
