Selain itu rumah cerdas dapat dilengkapi dengan peralatan keamanan seperti smart door yang dapat membuka maupun mengunci pintu secara otomatis ketika mengenali wajah pemilik rumah. Namun model smart door ini memiliki kelemahan yang di mana data yang tersimpan di dalam server maupun perangkat tidak diamankan secara end-to-end. Perangkat yang menyimpan data-data gambar pemilik rumah tidak dienkripsi dengan algoritma tertentu maupun  validasi keaslian data gambar. Sehingga masalah ini dapat dimanfaatkan pihak luar dengan melakukan masquerading atau menyamar dengan cara memasukkan data palsu di dalam perangkat. Berdasarkan masalah yang sudah dideskripsikan, penelitian ini memiliki tujuan untuk meningkatkan keamanan data end-to-end model dengan algoritma Advanced Encryption Standard. Selain itu, penelitian ini juga melengkapi tingkat keamanan dengan validasi integritas data terenkripsi menggunakan teknik Truncated Decimal-converted SHA-1 Checksum untuk membuat nilai hash unik yang dapat mencegah modifikasi di masing-masing data gambar. Dari hasil eksperimen perbandingan model yang dilakukan, terjadi kenaikan kebutuhan sumber daya perangkat sebanyak 0,81% peningkatan waktu proses, 18% penggunaan CPU, 5,3% penggunaan data, dan 5,04% untuk penggunaan memori seluruh proses. Namun peningkatan kebutuhan kinerja ini tidak sebanding dengan fitur keamanan yang dihadirkan oleh algoritma Advanced Encryption Standard dalam mengamankan data perangkat dan server. Sehingga dengan improvisasi keamanan ini diharapkan dapat meningkatkan keamanan data pemilik rumah dari pihak luar.","PeriodicalId":33096,"journal":{"name":"Jurnal ELTIKOM Jurnal Teknik Elektro Teknologi Informasi dan Komputer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45805874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Those needs can be achieved by utilizing bots. However, previous works only conducted bot-based testing for testing network capabilities. In this research, those works will be extended further ftotesting the capacity of a game server. The result of this research suggests that bot approach testing can simulate real players adequately. Other than that, the bot approach also can be scalable. However, the result also suggests that the bot approach still has some limitations as bots cannot simulate the dynamics shown by real players.

Document service aims to produce a document as evidence or validation of something according to the request of the applicant. The document service process often does not run smoothly because there are obstacles such as the number of applicants, limited space, and limited service time. In the modern era like today, these problems can be solved by making a special application for document services in order to make it easier for applicants to submit files to the service unit. This study aims to design and build a document service application to assist applicants in requesting document services. The main feature in the application that was built is that applicants can submit the required files online without having to queue. In addition, the application that was built also has a unique feature, namely that document files that have been submitted are automatically forwarded to the related unit. This feature can assist service units in managing documents, because the requirements file does not need to be submitted manually. There is an additional feature in the form of a document service process tracking system so that applicants can see the development of services directly. The application was developed using the Spiral Model. There are four stages carried out in this model. The four stages are planning, risk analysis, development as well as testing, and evaluation. In the final stage, an application evaluation is carried out by applying the ISO 9126 standard. Based on the results of user assessments, the level of user satisfaction in terms of usability is 77.43%, functionality 78.95%, and efficiency 77.86%.","PeriodicalId":33096,"journal":{"name":"Jurnal ELTIKOM Jurnal Teknik Elektro Teknologi Informasi dan Komputer","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41377703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This plant system consists of a controlled tank, a sup-ply tank, a water level sensor, a water faucet in the form of a motorized valve, PLC and HMI. In previous studies, the plant system used usually only has a controlled tank without a supply tank so that the control of the system becomes simpler. However, in this study a supply tank was also used so that the flow of water flowing in controlling the water level would depend on the water level of the supply tank and the opening of the water faucet. This plant system with a tank that has an open outlet pipe is a classic system that is non-linear so linearization is needed in its control. In order for the system to be linearized, it is assumed that both the supply tank and the controlled tank only operate within a certain value range. The realiza-tion of a water level control system using a PID controller was made and tested for its effectiveness at the setpoint values of 10 cm and 20 cm. Based on the simulation and experimental results, it was found that the system worked well where the PID control was able to stabilize the system at both setpoint values where the obtained overshoot were below 10%.","PeriodicalId":33096,"journal":{"name":"Jurnal ELTIKOM Jurnal Teknik Elektro Teknologi Informasi dan Komputer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41505928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berdasark an hasil eksperimen diperoleh bahwa terdapat hubungan antara kecepatan putaran turbin yang memutar generator dengan keluaran tegangan dan daya yang dihasilkan, sehingga diperlukan upaya mengendalikan kecepatan turbin angin agar dapat berputar sesuai setpoin yang ingin dicapai. Kontribusi dari penelitian ini berupa pengembangan sistem kontrol berbasis logika Fuzzy untuk mengendalikan kecepatan turbin VAWT dengan hanya menggunakan umpan balik berupa kecepatan turbin angin. Hal ini berbeda dengan penelitian sebelumnya dimana kecepatan angin dan keluaran daya dijadikan sebagai umpan balik. Untuk mengetahui karakteristik dari kecepatan turbin dan keluaran tegangan, serta hubungan antara kecepatan turbin dan kecepatan angin dengan variasi sudut pitch bilah, maka pengujian dilakukan dalam skala laboratorium dengan menggunakan blower. Untuk merancang rule base (aturan) Fuzzy, maka karakteristik dari respon turbin angin terhadap kecepatan angin diteliti terlebih dahulu. Kemudian kontroller berbasis logika Fuzzy dibuat dan diimplementasikan. Untuk menguji efektivitas kontroller Fuzzy yang dibuat, maka implementasi dilakukan pada turbin VAWT sedangkan simulasi diterapkan pada model PMSG turbin angin melalui Simulink/Matlab. Berdasarkan hasil pengujian melalui simulasi dan eksperimen dengan mengukur kinerja respon sistem kontrol menggunakan Integral Absolut Error (IAE) untuk masing-masing nilai setpoin kecepatan turbin (35, 45, 85, dan 100 RPM) diperoleh bahwa untuk nilai setpoin kecil maka nilai IAE akan semakin besar dibandingkan setpoin yang lebih tinggi. Persentase nilai rata-rata IAE untuk simulasi adalah 10,25% lebih tinggi dibandingkan dengan eksperimen. Hal ini kemudian menunjukkan bahwa pengendalian kecepatan turbin pada kecepatan rendah relatif lebih sulit dibandingkan dengan kecepatan turbin lebih tinggi.","PeriodicalId":33096,"journal":{"name":"Jurnal ELTIKOM Jurnal Teknik Elektro Teknologi Informasi dan Komputer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42708395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to obtain a controller that works accurately between the Proportional, Integral, and Derivative Controller (PID) and the Fuzzy Logic Controller (FLC) Algorithm by comparing the performance of the two algorithms in regulating the direction of the light tracker to detect the presence of sunlight. This solar prototype uses nine lamps as a simulation to determine the accuracy and precision of the angles of the two light trackers. The parameters compared in this test were the aspects of angular velocity and angle accuracy. The mean value of angular velocity obtained from the PID light tracking test results was 0.16 rad/s and the average linear velocity was 0.092 m/s whereas in the FLC light tracker, the average angular velocity value was 0.207 rad/s. Tests using a PID light tracker resulted in an X-axis accuracy of 45% and a Y-axis accuracy of 30%. The FLC light tracker, on the other hand, had an X-axis accuracy of 80% and a Y-axis accuracy of 30%.The precision value obtained by the PID light tracker on the X axis was 45% and the Y axis was 38%, while the precision value obtained by the FLC light tracker on the X axis was 71% and the Y axis was 33%. Based on the overall calculations, it can be concluded that the FLC light tracker has an increase in the speed value of 29% and an increase in the value of accuracy in the accuracy aspect by 35% and the precision aspect by 26% compared to the PID light tracker in previous studies.","PeriodicalId":33096,"journal":{"name":"Jurnal ELTIKOM Jurnal Teknik Elektro Teknologi Informasi dan Komputer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48818302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Isu kerusakan lingkungan merupakan dorongan untuk terus mengembangkan teknologi sumber tenaga yang komponen pendukungnya ramah lingkungan dan mudah didapatkan. Reaksi redoks pada sel yang berisi dua elektroda beda potensial, jika dihubungan dengan elektrolit dan beban sudah mampu membangkitkan tegangan dc. Pada pengujian ini kombinasi elektroda baterai menggunakan anoda logam magnesium dan logam aluminium, sedangkan katoda adalah logam inert atau carbon. Elektrolitnya adalah air garam yang mengandung ion Na dan Cl sebagai penghantar elektron sekaligus air sebagai reduktor. Yang menjadi fokus pengujian adalah tingkat salinitas elektrolitnya, dimana dibagi tiga tingkatan 27 ppt, 37 ppt dan 47 ppt. Parameter baterai adalah perubahan nilai tegangan, arus dan salinitas. Dilakukan masing-masing 3 kali pengujian terhadap masing-masing kombinasi elektroda. Hasilnya untuk elektroda magnesium, untuk salinitas 47 ppt terukur Voc=1,5 V dan Isc=1,52 A; sedangkan 37 ppt terukur Voc=1,454 V dan Isc=0,702 A; kemudian 27 ppt terukur Voc=1,433 V dan Isc = 0,625 A. Kemudian untuk elektroda aluminium untuk salinitas 47 ppt terukur Voc=0,898 V dan Isc=0,197 A; sedangkan 37 ppt terukur Voc=0,798 V dan Isc=0,184 A; kemudian 27 ppt terukur Voc=0,684 V dan Isc=0,125 A. Jadi hipotesa awal penelitian bahwa semakin tinggi tingkat salinitas elektrolit maka tegangan sel baterai ) semakin besar, untuk Voc dan Isc adalah benar. Untuk uji performa sel baterai air garam selama 24 jam dengan diberikan beban Resistor 0,47 Ω, dengan menganalisa perubahan nilai tegangan dan salinitas didapatkan bahwa hipotesa tidak benar.","PeriodicalId":33096,"journal":{"name":"Jurnal ELTIKOM Jurnal Teknik Elektro Teknologi Informasi dan Komputer","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48853454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
