Abstract

Fishing boats are generally made of wood, but over time the availability of wood for shipbuilding began to become difficult to obtain, considering the increasingly expensive price for the type and quality of wood, such as teak. So that other wood alternatives are needed to replace teak, such as laminated white teak. White teak wood can be an option because it grows fast and is widely planted and has a texture that is almost the same as teak. Therefore, it is necessary to conduct research to determine the strength value of white teak laminate through bending testing. The purpose of this study was to determine the value of the bending strength of laminated white teak (Gemelina arborea) and the comparison results with natural teak (Tectona grandis). This study uses five types of variations with the same size 2x2x36cm, namely KJ (Teak Wood), KJP (White Teak Wood), LKJP (White Teak Lamination) two, three, and five layers referring to the Japanese Industrial Standard (JIS Z 2113). , 1963) to determine the value of the bending strength, then an analysis of the average value of the bending test results was carried out and compared with the bending value of teak (Tectona grandis). From the results of the tests carried out, the average value for KJ is 215.53 kg/cm2, KJP 173.35kg/cm2, LKJP 2 layers 176.75 kg/cm2, LKJP 3 180.15 kg/cm2, LKJP 5 149.56 kg/cm2. Based on this average value, Laminate white teak is still lower than the average value of natural teak.

Abstract

Dalam metode magnetik, medan magnet anomali disebabkan oleh sumber medan magnet dipol. Setiap tempat memiliki sudut iklinasi dan deklinasi magnetik yang berbeda sehingga menyebabkan peta anomali magnetik bersifat kompleks dan interpretasinya menjadi relatif sulit. Untuk mengatasi kerumitan dalam interpretasi data magnetik, penggunaan transformasi reduksi ke kutub RTP sangat penting dilakukan. Tapis RTP dengan memanfaatkan fungsi-fungsi built in Matlab telah berhasil direalisasikan dan diaplikasikan pada data magnetik WDMAM wilayah Tapal Kuda-Jawa Timur. Nilai sudut inklinasi I = -32.82° dan sudut deklinasi D = 0.72° digunakan pada aplikasi RTP daerah ini. Anomali magnetik hasil RTP menunjukkan bahwa terjadi perubahan rentang nilai medan magnet yaitu dari -345.51 nT s.d 282.30 nT menjadi -975.37 nT s.d 782.38 nT. Selain itu, terjadi pergeseran lokasi klosur anomali magnetik positif dan negatif. Anomali magnetik positif mendominasi di bagian tengah sampai utara Wilayah Tapal Kuda dan diduga berkaitan dengan Zona Vulkanik Kuarter. Klosur-klosur anomali positif mengalami pergeseran letak ke barat di sekitar Gunung Bromo dan Gunung Argopuro. Anomali magnetik negatif mendominasi tepi selatan Wilayah Tapal Kuda dan diduga berkaitan dengan Zona Pegunungan Selatan. Klosur anomali negatif juga mengalami pergeseran letak yaitu ke barat daya mendekati gunung Semeru.

Abstract

Production activities at manufacture companies are often inconvenient. One of them is due to the incompatibility of workersanthropometry with the work facilities used. Disergonomics like this will cause complaints in the skeletal system. Complaints to this damage are termed musculoskeletal disorder (MSDS). The production process of making shoes at UD. Kurnia at the subordinate work station identified that work posture has the potential to cause injury to the arm, back and leg muscles with a percentage of 66.67%, 68.89% and 30%. So it is necessary to improve work posture. In this study, the OWAS method was used to identify and evaluate hazardous work postures. Meanwhile, to improve work posture, work facilities are designed using anthropometric data for subordinate work station workers. Owas identification results show that the work posture is more ergonomic. Then the results of the WinOwas software show that the improvement of work posture with the design of work facilities is included in category 1. Which means that the work posture is not dangerous. So it is directly believed that workers complaints on skeletal muscles or MSDs at subordinate work stations can be minimized.

Abstract

The Multibeam Echosounder is a tool for determining the depth of water by sweeping large areas of the seabed. The operating principle of this tool in general is based on the emission of pulses that are emitted directly towards the seabed and after that acoustic energy is reflected back from the seabed (seabel), several sound beams (beams) are electronically generated using signal processing techniques so that the beam angle is known. . Multibeam echosounder can produce high-resolution bathymetry data. The Multibeam Echosounder is characterized by the following parameters Frequency in the range 12 to 500 kHz. Sweep angle range is between +75 ͦto 85 ͦ, Accuracy generally decreases as swath width increases. The width of the sweep is 4x to 5x the water depth and the addition of the swath width depends on the depth of the survey. Using Multibeam Echosounder (MBES) acoustic equipment can improve data quality and the survey area coverage is able to obtain data coverage with a wider area, more detailed data as well as time efficiency and cost effectiveness..

Abstract

CEGEONE (CG) is a manufacturing industry company in furniture. It is a supplier company for the Horrison & Gil company. The company manufactures furniture from raw materials into semi-finished goods. The company produces its products on consumer demand (customized order). The overwhelming and varying amount of demand each period was a major problem in the company's production. Hence it takes scheduling. Production scheduling is an important process in production system. In the production process, particularly in the Shop Machine line there is often bottle neck. Under that, researchers did production scheduling at the Shop Machine with the Campbell Dudeck Smith (CDS) method. This method uses Johnson's algorithm that aims to determine the order of the job in order for the earned makespan to be smaller than before. Using production scheduling on shop machines, the company can reduce the total process time to complete the job by 95 minutes or 1 hour 35 minutes. Smaller compared to the previous total makespan of 250 minutes or 4 hours 10 minutes. So that shows total savings in production at 19.79%. The results of the study can be concluded that by using production scheduling on shop machines.
