Abstract

MEKANISME KERJA MESIN SHREDDER DAN ANALISIS KEGAGALAN PADA OPERASI PROSES PENGOLAHAN LIMBAH RADIOAKTIF PADAT MATERIAL TERKONTAMINASI. Mesin Shredder adalah mesin pencacah atau penghancur, dalam penerapannya di Pusat Teknologi Limbah Radioaktif (PTLR) mesin shredder digunakan untuk mencacah limbah radioaktif padat material terkontaminasi yang memiliki dimensi besar. Limbah radioaktif padat seperti jerigen, drum High-density polyethylene (HDPE), drum korosi dan lainnya. Tujuan akhir dari kegiatan ini adalah untuk memberikan informasi terkait alat shredder dan mengetahui hubungan antara mekanisme kerja proses pengoperasi mesin shredder, serta analisis kegagalan dalam proses pengolahan limbah radioaktif padat material terkontaminasi. Metode yang digunakan meliputi pengoperasi alat, pengamatan dan analisis kegagalan operasi alat. Hasil kegiatan diperoleh bahwa kapasitas produksi operasi mesin shredder sebesar 288 kg/jam untuk material Drum HDPE. Untuk menjaga agar operasi mesin dapat berjalan dengan baik diperlukan perawatan secara berkala. Analisis kegagalan dalam proses operasi alat shredder dipengaruhi oleh : operator, sistem operasi mesin, metode operasi, dan material bahan yang diolah.

Abstract

Developing a green open space by planting shade trees is an effort to evolve artificial ecosystem in urban areas. The aim of this study was toinventory the species of shade trees and their health condition in Palu city. This study was held during period of June until August 2015 at several street in Palu city. Parameter observed were depth of the wound to stem diameters of the trees and the number of damaged parts of the stem. The result showed that the highest damage precentage was at Munif Rahman street, on Johar (Senna seamea Lamk) species with 9,67 % depth of wound and 23,19 % damage parts of the stem.

Abstract

The SPR curve fitting using the Winspall simulator to determine the dielectric constant and the thickness of MEH-PPV film is presented. Experiment was performed by measuring the SPR curve of gold layer and gold/MEH-PPV layers based on Kretschmann configuration. First, the dielectric constant and the thickness of gold film are determined by fitting the SPR curve. And then the dielectric constant and the thickness of MEH-PPV are determined by fitting its SPR curve. The thickness result calculation from curve fitting for MEH-PPV shows comparable to the result from SEM. This method makes Winspall program as a simple tool in analysis and calculation to determine dielectric constant and thickness, layer by layer in deposition. Keywords:dielectric constant, MEH-PPV, SPR, Winspall, curve fitting, thickness

Abstract

Submission of the necessary permits public land burial place in the office area of Tangerang Regency funeral submitted by housing developers located in Tangerang district in order to meet the requirements of the Licensing process IMB. Now all land data submission submitted in writing through several procedures with the data fields that tend to repeat themselves. At the Office of Cemeteries Regional delivery of new land submitted by the developer to Tangerang Regency is still to record any data into a ledger and using Microsoft Office Excel, the data is recorded repeatedly and it resulted in the data search Proof of Ownership of Land TPU submitted by the developer housing to local government Tangerang any time the data is needed to be delayed. Some of the observations made to the current system in the data collection process of handing over land where the public cemetery (TPU) result of research that the problems being faced by the Office of the particularly within the system of delivery of TPU to Tangerang Regency include the length of time the process because of the many documents and procedures in each section must be followed to check files and keabshan data submitted. Keywords : land, developers, public cemetery
