Get PDFSeiring populasi manusia yang terus bertambah setiap tahun mengakibatkan permintaan terhadap energi juga meningkat dan keterbatasannya bahan bakar khususnya gas, munculah inovasi memberdayakan potensi yang ada dilingkungan sekitar untuk dijadikan bahan bakar alternatif khususnya enceng gondok. Pada realitanya pemanfaatan enceng gondok tidak diikuti dengan fasilitas mesin untuk mengektrasi. Untuk itu dibutuhkan teknologi yang mampu mengolah enceng gondok menjadi yang lebih bermanfaat ,dengan proses pencernaan anaerobik yakni dimana mikroorganisme memecah bahan biodegradable dalam keadaan tanpa oksingen, proses pembuatan biogas dimulai dengan mencacah eceng gondok kemudian ditambahkan variable air dan e4 sesuai variable pengencaran. Teknologi “Digester“ gas bio telah berkembang sejak lama namun aplikasi penggunaannya sebagai sumber energi alternatif belum berkembang secara luas. Beberapa kendala antara lain yaitu, digester tidak berfungsi akibat bocor atau kesalahan konstruksi, disain tidak user friendly, selain itu penerapan proses produksi belum terintegrasi. Proses produksi biogas yang akan dipakai berazaskan pada teknologi tepat guna dengan menggunakan digester dan aman untuk digunakan dalam skala rumah tangga sehingga mampu menghasilkan biogas sebagai energi alternatif. Pada pengujian ini menggunakan kapasitas 200 liter, dan menghasilkan energi yang dapat digunakan sebagai pembakaran selama 28 menit, dan menghasilkan kalor sebesar 2.016 KJ dan tekanan yang dihasilkan pada biogas sebesar 6 ps
Analysis of Import Gate Out Service Using Control Chart in PT Terminal Petikemas Surabaya
Get PDFGoods from abroad entering Indonesia must go through several stages of inspection. One of the final inspection stages of imported goods is through the import gate out of PT Terminal Petikemas Surabaya (PT TPS). Import Gate Out is the entry and exit access for each truck that will carry out activities in the area of PT TPS. The gate itself functions as a place to identify containers that will enter whether they are in accordance with the data and as a place of confirmation for the commanderer who will leave the port whether it has been completed and is in accordance with the existing procedures. In the import gate out process, there are operators in charge to ensure that the incoming or outgoing containers are in accordance with the existing system at PT TPS. In carrying out its duties, gate operators are expected to have the skills and speed to serve every container that will enter or leave PT TPS. To determine the extent of the performance duration of the gate operator PT TPS a research was conducted on the service time of the import gate out operator using descriptive analysis and control charts. This research was conducted using data collection techniques by observation. The results of this study indicate that the average transaction per day is 33.5 seconds
