Penerapan Metode Economic Order Quantity dan Reorder Point Pada Aplikasi Pengelolaan Persediaan Fumigasi
Get PDFFumigation controls pests by sealing a room using methyl bromide (CH3Br) and oxygen gas. This process requires a gas mask, fumigation plastics, sand snakes, and a certificate. The interview revealed that specific supply shortages cause fumigation delays in 15% of monthly orders. This research aims to develop an inventory control application by applying the economic order quantity (EOQ) and reorder point (ROP) methods to overcome the problem of running out of stock. The EOQ method determines the amount of inventory to order to avoid excess stock, while ROP determines the right time to order inventory. The study involved two types of testing: white box testing and comparing manual calculations with application calculations to determine their consistency using data from March to May. The white box testing results show that the program\u27s internal structure and logic run well. This is supported by evidence that each test case can pass two flow graphs resulting from cyclomatic complexity calculations. In addition, the results of testing the EOQ and ROP method calculations show an insignificant difference between the results of manual calculations and application calculations of 3.87%. This proves that application calculations for EOQ and ROP are running correctly and by the researchers\u27 expectations

Analisis Kerusakan Permukaan Jalan Berdasarkan Penilaian Dengan Metode SDI Dan IRI: (Studi Kasus: Jalan Raya Ciherang Kabupaten Bogor)
Get PDFTransportation infrastructure in the form of roads holds an important role in mass mobility. Sustainable usage combined with the increase in vehicle volume can lead to road damage, which eventually affects its construction condition and has implications for quality, comfort, safety, and traffic flow. Therefore, periodic analysis of road surface damage is crucial to determine whether the road is in good condition or requires repair and maintenance. Jalan Raya Ciherang in Bogor Regency is categorized as a busy district road, with a length of 2 km, serving as a secondary local road. The Surface Distress Index (SDI) and International Roughness Index (IRI) methods were used to assess the road surface condition. By comparing visual assessments and using the Roadroid application, the results were more effective in determining the level of damage and finding appropriate actions to solve the problem. The analysis showed that the average percentage of road damage using the SDI and IRI methods, the highest percentage of SDI values indicates a good condition at 50%, while the highest percentage of IRI values indicates a combination of good and fair conditions, both at 37.50%. Referring to the data on determining the type of road condition management from Bina Marga, 2011, it was necessary to perform routine maintenance. According to information from Kebina-Margaan, and Dinas Pekerjaan Umum 2007 regarding road service conditions, Jalan Raya Ciherang falls into the category of Mantap service condition.Infrastruktur bidang transportasi berupa jalan merupakan bagian penting bagi pergerakan masyarakat, Penggunaan jalan yang berkelanjutan serta volume kendaraaan yang meningkat dapat menyebabkan timbulnya kerusakan jalan yang mempengaruhi kondisi konstruksinya sehingga akan berdampak pada tingkat kualitas, kenyamanan, keamanan, dan kelancaran berlalu lintas. Analisa kerusakan permukaan jalan secara periodik sangat dibutuhkan untuk mengetahui kondisi jalan tersebut dalam kondisi baik atau dalam kondisi yang membutuhkan perbaikan dan pemeliharaan. Ruas Jalan Raya Ciherang Kabupaten Bogor dikategorikan sebagai jalan kabupaten yang cukup padat lalu lintasnya,dengan panjang 2 km dan merupakan jalan lokal sekunder. Metode yang digunakan untuk penilaian kondisi permukaan jalan adalah metode Surfece Distress Index (SDI) dan International Roughness Index (IRI). Dengan membandingkan penilaian secara visual dan menggunakan aplikasi Roadroid maka hasilnya akan lebih efektif untuk digunakan sebagai acuan dalam mengetahui tingkat kerusakan dan penanganannya. Hasil Analisis menunjukan perbandingan rata-rata persentase kerusakan jalan menggunakan metode SDI dan IRI, persentase terbesar nilai SDI berada pada kondisi baik yaitu 50% sedangkan persentase terbesar pada nilai IRI berada pada kondisi baik dan sedang dengan nilai keduanya 37,50%. Nilai index rata-rata kondisi permukaan jalan yang ditinjau pada Ruas Jalan Raya Ciherang memiliki Kondisi baik dan sedang mengacu kepada data penentuan jenis penangan kondisi jalan yang bersumber dari Bina Marga,2011 perlu dilakukan berupa pemeliharaan rutin dan menurut informasi Kebina-Margaan, Dinas Pekerjaan Umum 2007 mengenai kondisi pelayanan jalan maka, Ruas Jalan Raya Ciherang termasuk dalam Kondisi Pelayanan Mantap

Uji Impact Material Komposit Campuran Serat Bambu Dan Pasir Besi Menggunakan Metode Hand Lay Up
Get PDFA composite is one of the materials that is a mixture of two or more materials to form a third, more useful material. In this study, researchers chose bamboo fiber and iron sand as reinforcement for composite materials because the selection of bamboo fiber as a research material took into account the potential of bamboo fiber in Indonesia which is abundant and has not been utilized properly. The purpose of making bamboo fibrous composite materials aims to find a material that is lighter stronger and more elastic, can be developed into other products such as the manufacture of drone frames, aircraft bodies, brake pads. The method used is an experiment with making specimens using the hand lay up method and testing using impact testing and micro photo testing. Impact testing is used to determine the properties and characteristics of the material in the form of strength, hardness, and ductility of the material while for micro photos it is used to determine the bond of the material composition with the best impact test. The test standards used are ASTM D6110-10 with random fiber arrangement and ASTM D6110-04 with the arrangement of woven fibers, with variations in volume composition of bamboo fiber and iron sand particles. In the D6110-10 specimens, the best specimens were found in the variation with the most bamboo fibers, namely 35S10 P with an impact energy of 4.27 J and an impact price of 0.04 J / mm2, while the lowest variation was found in the most iron sand, namely 35P10S with an impact energy value of 2.26 J and an impact price of 0.02 J / mm2. In the D6110-04 specimen also showed the same characteristics as the ASTM D6110-10 specimen, the 30S30P variation or the composition of the most bamboo fibers had an impact energy value of 4.09 J while in the 10S10P variation it was only 1.47 J. Thus the more bamboo fibers will make the impact strength of the specimen higher.A composite is one of the materials that is a mixture of two or more materials to form a third, more useful material.
