Abstract

Project B merupakan salah satu usaha yang berkiprah dalam bidang jasa cuci, perawatan, dan custom sepatu yang sejak 2019 telah beroperasi. Project B menyediakan jasa cuci sepatu dan jasa cuci dihitung per item dan jenis material sepatu di antaranya kanvas, suede, kulit sintetik atau autentik, sepatu berwarna putih, sepatu anak, custom sepatu sesuai dengan keinginan pelanggan. Proses pengelolaan pada kegiatan jasa cuci sepatu pada di Project B masih bersifat manual. Dalam hal pendataan sepatu pelanggan yang masih sangat kurang efisien karena pendataan masih menggunakan kertas dan tulis tangan. Pada saat pelanggan melakukan pemesanan sepatu yang dijemput ke lokasi, pemesanan masih via cara menghubungi pemilik usaha yang dimana terkadang bisa terjadi respon balasan yang lambat atau tidak terbaca oleh pemilik usaha. Selain itu, laporan bulanan juga bisa salah dalam perhitungan, karena catatan atau bukti pembayaran terselip hingga ada transaksi yang tidak tercatat. Untuk mengatasi masalah tersebut, diperlukan suatu sistem informasi manajemen perawatan sepatu yang dapat meningkatkan efektifitas dan efisiensi kinerja bisnis Project B. Tujuan dari penulisan ini adalah untuk membangun sebuah aplikasi perangkat lunak berbasis web dengan menggunakan bahasa pemrograman PHP dan database MySQL untuk merancang sistem manajemen perawatan sepatu.

Abstract

Network connection has an important role for the community, especially for students of the Indramayu State Polytechnic Department of Informatics. which serves to assist practical activities, which are carried out at the Informatics Engineering Department Laboratory. DHCP Rogue is a threat that can occur on a network, which can deflect data packets that pass. This action can be done by an irresponsible person. Therefore, there is a need for network security to prevent threats from DHCP Rogue, to overcome this problem, a DHCP Snooping method is needed to prevent DHCP Rogue on the network. Given the threat, he carried out several stages by configuring DHCP Snooping, configuring the DHCP server, and monitoring the network using the Wireshark application. Which is implemented at the Informatics Engineering Laboratory, to maintain data packets that pass, and can find out if there is a DHCP Rogue in the network. In this article, the results of preventing DCHP Rogue can be handled using the DHCP Snooping method through testing results, and monitoring on the network

Abstract

The rapid development of information systems in the current era of globalization has made almost all aspects of life unavoidable from the use of computer devices, especially in educational institutions. The number of SMA/equivalent in Indonesia is 15,497, namely in public schools there are 7,203 (46.48%) and private schools 8,294 (53.52%). West Java Province has the highest number of schools, namely 1,823 schools. Meanwhile, Indramayu Regency has 89 SMA/equivalent with details of 26 state and 63 private. One of them is SMA NU Tenajar Kidul. The school has problems with the presence of students. Often students do not enter school without explanation. However, after follow-up was carried out by the school, they received information from the parents of the students that their children were leaving home from home. So that these students are truant and cause not get knowledge in school. The need for a touch of technology that can bridge the school with parents of students. So that when there is a problem that one of the students is absent, the school can provide information to parents quickly and accurately. Therefore WhatsApp API is the right choice to provide attendance information to parents. The system was built using the nodeJS programming language and got the test results of 40 messages, getting the message sending process time of 0 milliseconds. While the time needed by the API to process the message sending is the longest 0.10522 milliseconds. If you calculate the average length of the message sending process, it is equal to 0.037826 milliseconds. Thus the WhatsApp API that has been built is very effective with performance under 1 second. All messages stored in the table are 100% sent.

Abstract

The Parish of Santa Maria Was Appointed To Heaven Eban is one of the parishes which was inaugurated on March 23, 1952 by the Apostolic Vicariate of Atambua-Timor. This parish is located in West Miomaffo, North Central Timor District, East Nusa Tenggara Province, with around 12,000 parishioners spread across 23 neighborhoods. Service activities provided by the Parish Priest are recorded and stored by the Parish Secretariat partially manually and partially using a computer application. The data processing system used does not yet have a database stored on a computer, so if a church or congregation needs information, each file must be checked one by one to obtain the data needed. So it will take a long time in the search process. Based on these problems, a website-based Parish Administration Information System (SIAP) is needed so that it can provide better service in conveying existing information. SIAP is expected to be able to manage administrative data such as registration for Sacrament Services. The sacraments served are Baptism, First Communion, Confirmation and the Sacrament of Marriage. SIAP development uses the Incremental system development model. The reason for using this method is because this method is considered to be able to accommodate changes flexibly and has a lower risk to the system development process.

Abstract

The hospital as one of the individual health service facilities is part of the health resources that are very much needed to support the implementation of health efforts. Hospital information systems can encourage increased efficiency and effectiveness of services in hospitals. The process of planning an information system in a hospital is one of the important points that must be prepared. The Kumala Siwi Kudus Hospital has started implementing online registration, but in its planning the Kumala Siwi Kudus Hospital is still in a hurry so that the implementation experiences several obstacles. When viewed from the benefits generated from the system, it is necessary to evaluate the success of its implementation using an information system evaluation model, one of which is the Human Organization Technology-FIT (HOT-FIT). Primary data collection was carried out by interviews and the results of questionnaires conducted on research subjects. The data obtained is a description of the situation when the research was carried out (cross sectional). The results of this study indicate that there is a significant influence on the construct of system quality on the construct of system use.

Abstract

The purpose of this research is to reduce the factors of SMS security by using SMS encryption application using cipher feedback 8-bits mode on android device. The first factor, which is the physical factor, is if the mobile phone is held by another person who are not the owner of the phone. That person can read and get information from the message on that mobile phone. The second factor is the safety messages in the system, this is all because the provider of mobile phones is only encrypting the messages during the transmission process, while in the storage process in the provider of mobile phones, the messages is saved as plaintext. The step of the process on cipher feedback 8-bits mode is started from filling the SMS with plaintext and initialization vector (IV) and key. Then the encryption function will process them to produce the keystream. The early 8 bits of keystream will be exclusive-or-ed (XORed) by the early 8 bits of plaintext and the result will be sent back to left most block from early IV with shift register process, and these processes will be repeated until resulting a chipertext message filled by rows of hexadecimal. The ciphertext as a result from the system will be sent to the receiver through the server, so the real message which is addressed to the receiver will be safe. Based on the result above, it can be concluded that the message would not be read except by the sender and the receiver.
