Abstract

Peningkatan kebutuhan listrik di Indonesia saat ini berbanding terbalik dengan sumber pembangkit listrik yang tersedia. Saat ini, pemerintah menggencarkan pembuatan pembangkit listrik energi baru terbarukan untuk menggantikan pembangkit listrik yang menggunakan bahan bakar minyak bumi dan batubara. Pada tahun 2023, pemerintah menargetkan 23 % dari pembangkit listrik yang ada di Indonesia harus berasal dari pembangkit listrik energi terbarukan. Salah satu pembangkit yang gencar dibangun adalah pembangkit listrik tenaga surya. Untuk di kotakota besar, pemerintah menghimbau dan mengajak masyarakat untuk menggunakan panel surya skala rumahan untuk membantu mengurangi polusi udara dari pembangkit yang digunakan pemerintah yang masih menggunakan bahan bakar batubara dan minyak bumi. Dari permasalahan diatas, timbul ide untuk membuat tugas akhir ini. Disini saya akan membuat kalkulator yang bisa digunakan untuk memperkirakan berapa energi yang harus dibangkitkan oleh panel surya dan berapa biaya yang dibutuhkan untuk menghasilkan energi listrik tersebut. Kata Kunci : Photovoltaic, Energi baru terbarukan

Teradapat 3 jenis produk sarana dan pra sarana kereta api yang di produksi, salah satunya adalah shoulder for e-clip. Berdasarkan data historis bulan Januari 2017 sampai dengan Desember 2018 produk ini mengalami rata-rata defect sebesar 5.22% per bulannya sedangkan toleransi defect yang ditetapkan perusahaan sebesar 2%. Jenis cacat yang paling banyak menghasilkan defect adalah beku dini yang terjadi pada saat proses penuangan. Penelitian ini akan difokuskan untuk mengurangi cacat beku dini pada proses penuangan dengan menggunakan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control). Pada tahap define dilakukan pengidentifikasian CTQ menggunakan metode delphi dan pembuatan diagram SIPOC. Pada tahap measure dilakukan perhitungan stabilitas proses menggunakan peta kontrol p dan perhitungan kapabilitas proses sehingga diketahui rata-rata DPMO sebesar 3739 sedangkan untuk rata-rata level sigma sebesar 4.22. Pada tahap analyze digunakan tools fishbone diagram sehingga didapatkan faktor penyebab masalah adalah man, method, material, tools, dan environment. Setelah itu digunakan pendekatan FMEA untuk menentukan mode kegagalan yang akan diprioritaskan untuk dilakukan perbaikan sehingga didapatkan faktor method dan man yang memiliki nilai RPN tertinggi. Maka dari itu pada tahap improve usulan perbaikan di prioritaskan terhadap faktor man dan method untuk mengurangi cacat beku dini yaitu dengan pemasangan pirometer dan pembuatan checksheet. Kata kunci: Shoulder for e-clip, defect, DMAIC, beku dini, penuangan, CTQ, DPMO, FMEA Abstract PT Pindad is an industrial and manufacturing company engaged in manufacturing military and commercial products including the forging & cast division. There are 3 types of railway facilities and preproduction products produced, one of which is the shoulder for e-clip. Based on historical data from January 2017 to December 2018 this product experienced an average defect of 5.22% per month while the defect tolerance set by the company was 2%. The type of defect that produces the most defects is cold shut that occurs during the pouring process. This research will be focused on reducing cold shut defects in the pouring process using the DMAIC approach (Define, Measure, Analyze, Improve, Control). At the define stage CTQ is identified using the delphi method and SIPOC diagram making. In the measure phase, the calculation of process stability using p control chart and process capability calculations are calculated so that the average DPMO is 3739 while the average sigma level is 4.22. In the analyze stage, a fishbone diagram tool is used so that the causes of the problem are obtained which is by man, method, material, tools, and environment. After that, the FMEA approach is used to determine the failure mode that will be prioritized for improvement in which the method and man factors have the highest RPN values. Therefore, in the improve stage proposed improvements prioritize the man and method to reduce cold shut defects, namely by installing pyrometers and making checksheets.

Abstract

Abstract The application of monitoring over Wireless Sensor Network (WSN) is highly demanded to be implemented in the Internet of Things (IoT). The problem that appears in IoT is the general purpose microprocessor is still highly used, which causes more energy used than it is needed. Although, an Application Specific Integrated Circuit (ASIC) can be used to make a more efficient energy application, it is more expensive and permanent, which means it can't be changed or reconfigured. This thesis presents a method to design a specific purpose microprocessor by compressing an image in DLX microprocessor, which can still be reconfigured by optimizing machine instruction needed in the microprocessor. Prior to DWT process, an image will go through pre-processing stage. The stage will be done in Matlab to turn an RGB image into a grayscale image, and the matrix of the grayscale image will be obtained. This matrix will be the input for Haar DWT machine instruction. The machine instruction is simulated in WinDLX, a simulator for DLX microprocessor. After the simulation has finished, the statistics of the simulation will be analyzed to conclude whether the machine instruction is optimum enough. The result of Haar DWT machine instruction is the same as the result obtained from Matlab, which means the machine instruction is capable to do the image compression. Out of 92 kinds of instruction, Haar machine instruction only needs 20 kinds of instructions used. This shows that the program will not waste energy for unused instruction. From the statistics obtained, the total cycles executed from the pipelined DLX microprocessor is 1239 cycles, where a non-pipelined microprocessor would need 2755 cycles to execute the program. This means the program is a more efficient method to run a Haar DWT compression. Keywords: optimum machine instruction, DLX microprocessor, DWT image compression, internet of things (IoT), wireless sensor multimedia networks. 1. Introduction As the technology grows more and more in human life, the phrase "Internet of Things" is not an uncommon phrase to be involved in the growth. Kevin Ashton was the first person to use the term “Internet of Things” in 1999. At that time, Kevin and his team were developing an extension of the internet to accommodate things and it inspired him to the term “Internet of Things” [1]. The idea of IoT was developed in parallel to WSNs [2]. Wireless Sensor Network or WSN is a network of a large number of nodes that cooperatively sense the environment. The application of the WSN has been done since the 1980s but then became more common to use in 2001 for industrial and research purposes [2]. The WSN is largely applied in many applications, such as environmental monitoring, industrial and infrastructure, and military surveillance. Although WSN is very useful for the convenience in the society, this technology also comes with some issues [3], such as the minimum exposure path [4] and the energy sink-hole [5], [6] in WSN. The main problem discusses in this thesis is the energy lifetime of the WSN itself, which people have been paying attention as well. Sensor nodes are usually powered by limited lifetime batteries. Changing the batteries frequently become very inefficient for a long use of WSN. There are many suggestions to this specific problem, such as wirelesspowered sensor networks [7] and harvesting solar energy as a wireless charging for the WSN [8]. However, even if the additional power can be harvested to the WSN, the resource is still limited for frequent use. Image compressing is a more detail strategy to reduce excessive energy consumption of WSN. There are many methods of image compressing used for this problem [9], [10]. This thesis uses the image compression strategy by creating DWT machine instruction to be inserted in DLX microprocessor so that the processor will run the specific instructions. This strategy will be efficient to get the most ideal microprocessor to be implanted in the WSN. Furthermore, the WSN will not be wasting energy on other microprocessor instructions that will be left unused. The purpose of this thesis is to analyze the energy efficiency WSN by reconstructing the machine instruction. The benefit is this method can be successfully implemented on WSN in multimedia sector. The problem can be formulated as how effective DWT for optimum machine instruction affects the WSN energy efficiency in multimedia monitoring system. This thesis uses DLX microprocessor and Haar DWT algorithm in DLX assembly language. The parameters for this paper are the compression result, the power consumption, and ISSN : 2355-9365 e-Proceeding of Engineering : Vol.6, No.2 Agustus 2019 | Page 3542 the speed of simulation. The completion of this thesis uses several methodologies, such as literature study, designing the system, and simulation.

Abstract

Abstrak Perkembangan jaringan internet yang semakin pesat dan besar mendorong peningkatan penggunaan jaringan Wireless Local Area Network (WLAN) sebagai gateway bagi endpoint device untuk mengakses jaringan internet. WLAN memiliki kelebihan yakni memiliki kecepatan transfer data tinggi, praktis digunakan, dan fleksibel karena menggunakan media transmisi gelombang radio untuk terhubung dengan user. Namun karena transmisi paket dilakukan secara terbuka membuat jaringan WLAN lebih rentan terhadap pencurian data dan serangan cybers. Untuk mengamankan jaringan WLAN terdapat sistem keamanan yang sudah mumpuni yakni Wireless Intrusion detection system (WIDS). WIDS memiliki prinsip yang sama dengan IDS namun dikhususkan untuk melindungi jaringan WLAN dari serangan. Sehingga WIDS cocok dipasangkan pada jaringan WLAN karena dapat mendeteksi serangan di udara sehingga admin jaringan dapat melakukan tindakan sebelum serangan merusak komponen penting yakni server, access point, dan client. Dalam tugas akhir ini, sistem keamanan WIDS akan dipasangkan pada jaringan WLAN yang dijalankan menggunakan emulator Mininet-Wifi. Sistem yang telah dibuat diuji menggunakan serangan yang khusus ditujukan untuk jaringan WLAN (WEP, WPA, WPA2 Cracking; Denial of Service; dan Evil-Twin) dan diuji performansi QoS-nya saat sebelum dan setelah dipasang WIDS dan saat dijalankan dengan trafik video dan VoIP dengan bacgkround traffic 10 Mbps hingga 58 Mbps. Hasilnya sistem dapat mendeteksi serangan WEP, WPA, dan WPA2 Cracking; dan Denial of Service namun tidak dapat menentukan sumber serangan dengan tepat (false positive). Untuk serangan Evil-Twin dapat dideteksi dengan baik oleh sistem. Dari uji performansi, didapat hasil pemasangan WIDS hanya berpengaruh terhadap kenaikan delay rata-rata. Begitu juga dengan kondisi background traffic yang berbeda hanya terjadi peningkatan secara linear pada delay rata-rata. Untuk jitter throughput, dan packet loss cenderung stabil dari hasil dua uji performansi yang dilakukan. Kata Kunci : WLAN, WIDS, access point. Abstract The development of increasingly fast and large internet networks has encouraged an increase in the use of Wireless Local Area Network (WLAN) networks as a gateway for device endpoints to access internet networks. WLAN has the advantage of having high data transfer speeds, practical use, and flexibility because it uses radio wave transmission media to connect with users. However, because packet transmission is carried out openly, making WLAN networks more vulnerable to data theft and attack by cybers. To secure the WLAN network, there is a security system that is qualified, namely the Wireless Intrusion detection system (WIDS). WIDS has the same principles as IDS but is specifically intended to protect WLAN networks from attacks. So that WIDS is suitable to be installed on a WLAN network because it can detect attacks in the air so the network admin can take action before the attack damages important components, namely the server, access point, and client. In this final project, the WIDS security system will be installed on a WLAN network that is run using the Mininet-Wifi emulator. Systems that have been made are tested using attacks specifically intended for WLAN networks (WEP, WPA, WPA2 Cracking; Denial of Service; and Evil-Twin) and QoS performance is tested before and after WIDS is installed and when run with video and VoIP traffic with backround traffic of 10 Mbps to 58 Mbps. The result is that the system ISSN : 2355-9365 e-Proceeding of Engineering : Vol.6, No.2 Agustus 2019 | Page 4401 2 can detect WEP, WPA, and WPA2 Cracking attacks; and Denial of Service but cannot determine the source of the attack correctly (false positive). Evil-Twin attacks can be detected properly by the system. From the performance test, it was found that the WIDS installation results only affected the increase in average delay. Likewise, with different background traffic conditions there is only a linear increase in average delay. For jitter throughput, and packet loss tend to be stable from the results of two performance tests performed. Keywords : WLAN, WIDS, access point.
