<![CDATA[Cribs are one of the baby support products used after the baby is born. Parents as consumers expect products that are used more concise, in accordance with the residence and the price is more economical by not reducing the quality of products and still refers to the principle of ergonomics, so that the product is less competitive with existing products in the market therefore it is necessary to design ababy crib and ergonomic multifunction cabinets by using the productrecycle drum. The purpose of this design is expected to answer and be a solution to the wishes of consumers, especially parents who have a baby by presenting new innovations. The design uses anthropometry theory to produce a convenient product used by the user. Anthropometric data collection is done directly with the required body dimensions are height upright, shoulder width and hand reach. Stages of data processing ie test data adequacy, test data uniformity and percentile calculations. The Results of design of ergonomic crib and cupboardare made based on the anthropometry of the human body, as well as economical because it is made using recycled materials....]]>

<![CDATA[Dengan semakin meningkatnya persaingan pada bidang perminyakan, maka perusahaan harus melakukan perbaikan peralatan untuk menjaga kestabilan perusahaan dalam mencapai visinya. Salah satu faktor yang perlu diperhatikan adalah sistem perawatan pencegahan (preventive maintenance). PT. Petrochina International Jabung Ltd merupakan salah satu perusahaan yang bergerak di bidang Minyak Dan Gas Bumi yang berada di Kabupaten Tanjab Timur Kec. Geragai. Tugas Akhir ini membahas tentang Analisa Keandalan dan Penentuan persediaan Komponen Pengering Udara (Air Dryer) di PetroChina International Jabung Ltd. yang mana diperlukan untuk mengetahui keandalan apabila terjadi gangguan kerusakan spare part . Untuk pemecahan permasalahan ini perlu dilakukan satu metode reliability dengan menerapkan fungsi laju kerusakan distribusi weibull untuk menentukan jumlah persediaan komponen kritis dalam jangka waktu satu tahun. Hasil penelitian menunjukkan bahwa semua komponen kritis berdistribusi weibull. Berdasarkan komponen kritis yang telah ditentukan dengan metode ABC dikaitkan dengan fungsi laju kerusakan pada metode reliability maka persediaan untuk komponen kritis selama periode satu tahun untuk masing komponen kritis adalah Pre Filter dan After Filter sebanyak 4 unit pemesanan optimal (Q*) dan 2 unit titik pemesanan kembali (r).]]>

<![CDATA[PT. Golden Energi Mandiangin adalah sebuah perusahaan yang bergerak dalam Manufacturing Crumb Rubber dimana dalam operasionalnya memerlukan pengendalian persedian bahan baku untuk produksi. Masalah optimalisasi pemesanan bahan baku merupaka hal yang sangat penting dalam suatu perusahaan, sehingga masalah ini terus dipelajari dan dikembangkan. Analisis yang digunakan adalah metode EOQ. Penelitian dan hasil perhitungan yang dilakukan, apabila menggunakan metode EOQ dalam pengadaan bahan baku akan didapatkan penghematan biaya.. Jika penyelenggaraan bahan baku didasarkan pada metode EOQ terdapat penghematan biaya tahun 2013 sebesar Rp. 392.013.491,- tahun 2014 sebesar Rp. 714.924.228,- tahun 2015 sebesar Rp. 341.627.892,-.Dengan demikian berarti ada perbedaan yang sangat nyata antara kebijaksanaan persediaan yang dilakukan menurut perusahaan dengan perhitungan menurut EOQ.]]>

<![CDATA[Simulasi tanggap darurat kebakaran adalah satu upaya untuk menjaga keperdulian karyawan terhadap kecelakaan yang dapat terjadi pada saat bekerja. Kualitas simulasi tanggap darurat dapat ditingkatkan dengan memperhatikan kualitas faktor pendukungnya. Faktor yang dapat meningkatkan kualitas simulasi tanggap darurat kebakaran adalah pelatihan (training) dasar pemadam kebakaran dan pertolongan pertama serta pengarahan (sosialisasi) mengenai bagaimana prosedur simulasi tanggap darurat kebakaran. Nilai koefisien regresi pelatihan dasar pemadam kebakaran dan pertolongan pertama (X1) sebesar 0,516 sedangkan pengarahan/sosialisasi simulasi tanggap darurat kebakaran (X2) sebesar 0,334. Dengan hasil ini maka dengan meningkatkan kualitas pelatihan simulasi tanggap darurat kebakaran sebesar 0,516 persen lebih besar dibandingkan dengan pengarahan atau sosialisasi yang hanya 0,334 persen.]]>

<![CDATA[The aim of this research is to develop membrane material and analyse the membrane performance in liquid waste management of CPO industry to separate suspended solids. Conventional waste treatment has not been able to reach the minimum regulatory standards that have been set. Land area constraints and waste management techniques are complex and produce large sludge volumes. Besides specifically for managing liquid organic waste, the difficulty of the process of degradation of waste due to the high quantity and content of contaminants that can reach up to 40,000-120,000 mg / l for COD. In this study composite membrane made by titanium dioxide in the membrane polyvinylidene fluoride was blend very well and suited to remove suspended solids in the wastewater. The optimization result obtained is the addition of TiO2 2% produce maximum flux with the value of 180 L / m2.hr and the percentage of 92% fitration. The results of the filtration process conditions were the total suspended solids (TSS) by 99.63% and ammonium nitrogen (NH3-N) by 92.82% is the ABFR process conditions at 2.25 ml / min, HRT at 276.93 min, MLSS concentration at 4.50 g / L, and the pH at 6.50. So it can be concluded that titanium dioxide resulted the minimise of average poresize and enhance the hydrophilicity of membrane that resulted the maximum flux of this process.]]>

<![CDATA[The ship production process is largely a welding work. About one-third of the total number of jobs in the construction stage is regulated Welding Procedure Specification (WPS) which is regulates welding rules such as class material, electrodes, how to weld the bevel shape long distance bevel (gap) and slope angle. Based on the WPS used of construction HN 309 Tanker Ship the length of the bevel distance (gap) in welding SMAW is 2,63 mm. Bending tests are performed to regulate strength of materials due to loading without causing deformation. This research study aims to determine the bending strength (quality) of the welders is 1 mm plate with variants of are 100 A 120 A and 140 A. The welding method ASTM A36 plate which is do bending test to using MTS landmark ASTM E 190-2003. The flexural strength of bending test from the three specimens based on current variation is the value of current strength 140 A is best compared to the current strength of 120 A and 100 A, the value of 140 current strength is 1.76107649 kN /mm2, current value of 120 A is 1,50230752 KN/mm2 and 100 A current strength of 1,44976202 kN /mm2 with a linear regression value is 0,872. So that the 11 mm plate welding procedure with a 2 mm gap can be used in the ship building production process.]]>

<![CDATA[In the industrial application, the pneumatik system was used to help the production process that uses automatic control. The pneumatik system trainer that already exists in the Politeknik Jambi workshop still uses a manual control system. In this discussion, the writer wants to modify the PLC-based electro-pneumatik policy (programmer logic controller). Pneumatik systems were all systems that use power in the form of compressed air and are used to produce work. The first compressed air by the compressor and stored in the storage tube. The storage air was treated so that the pneumatik system can function correctly. The compressed air was regulated for use by a pneumatik control system, which is connected to the solenoid valve to drive three cylinders of double-acting opposite motion..]]>
