Infrastructure as a Service is one of the cloud computing services that is a choice of several users, it is very important to know the performance of each existing platform in order to get the maximum result according to our needs. In this study, testing 3 platforms of cloud computing service providers are VMWare ESXi, XenServer, and Proxmox, using action research methods. From the results of performance measurements, then analyzed and compared with the minimum and maximum limits. The tested indicators are response time, throughput, and resource-utilization as a comparison of server virtualization performance implementations. In the resource utilization testing when the condition of installing an operating system, CPU usage on the Proxmox platform shows the lowest usage of 10.72%, and the lowest RAM usage of 53.32% also on the Proxmox platform. In the resource test utilization when idle state shows the lowest usage of 5.78% on the Proxmox platform, while the lowest RAM usage is 57.25% on the VMWare ESXi platform. The mean resource utilization tests indicate that the Proxmox platform is better. At the throughput test when the upload measurement of the XenServer platform is better 1.37 MB/s, while the throughput test when the download of the VMWare ESXi platform is better than 1.39 MB/s. On response time testing shows the platform VMWare ESXi as the fastest is 0.180 sec.</p> Deni Marta M.

Routine monitoring is needed, especially temperature, humidity and ammonia levels. In this study, the authors propose an embedded system that can detect temperature, humidity and ammonia levels. This system works by sending temperature, humidity and ammonia gas information routinely once a day to the henhouse operator via text message (SMS), or information will be sent if environmental conditions are above/below the threshold. The embedded system was built using microcontrollers, temperature and humidity sensors as well as ammonia sensors. The microcontroller uses Arduino. Temperature and humidity sensors use DHT11, while the ammonia level sensor uses MQ-135. Embedded system communication uses the GSM SIM800L module, this module is responsible for sending the henhouse environmental conditions to the operator via SMS. Testing is done in two stages, namely functionality and connectivity. The functionality test proves that the sensor can produce information on temperature, humidity and ammonia levels by comparing it with conventional tools. The connectivity test proves that the GSM SIM800L module can send monitoring data every day and certain conditions.</em></p> Fathurrahmani Fathurrahmani Wiwik Kusrini Khairul Anwar Hafizd Arif Supriyanto ##submission.copyrightStatement## 2019-11-02 2019-11-02 19 1 53 61 10.30812/matrik.v19i1.490 Pengujian Usability dengan Teknik System Usability Scale pada Test Engine Try Out Sertifikasi https://journal.universitasbumigora.ac.id/index.php/matrik/article/view/503 <p style="text-align: justify;"><em>Test engine try out is an information system used by prospective alumni students to practice the questions in taking the certification exams at Bina Darma University.

To ascertain whether the test engine is in line with the expectations and needs of the participants try out then an evaluation is carried out. The evaluation technique used is usability with the system usability scale approach. System usability scale is an information system evaluation technique that looks at three aspects, namely adjective rating, grade scale, acceptability by involving end users in the evaluation process. In the process of evaluating the usability scale system, ten instruments were used as a measure of evaluation. From the evaluation, the final result is 87.33.

Nahwu theory is the study of structure of Arabic sentences. By learning nahwu, being able to distinguish subjects, predicates and objects in sentences. One of the fields in the computer that studies about human language processing is NLP (Natural Language Processing), which is natural human language processing through syntactic analysis of sentences structure. One method to analyzing syntactic of sentences is stemming. One variant of the stemming algorithm is Light Stemming algorithm. Light Stemming algorithm is an algorithm that only removes prefix and sufix. Based on the tests conducted, the light stemming algorithm is able to detect nahwu with an accuracy rate of 82.22%. The 17.78% failure rate occurs because words that do not have an affix will be detected automatically the type is fi’il (verb), even though the fact may be that the type is isim (noun), and the failure of the detection results is also due to not being able to stemming the words that have affix in the middle (infix), because indeed the process of light stemming only eliminates the sufix and prefix.</p> Mudafiq Riyan Pratama Muhammad Yunus ##submission.copyrightStatement## 2019-11-02 2019-11-02 19 1 109 118 10.30812/matrik.v19i1.509 Pemanfaatan Aplikasi Customer Relation Management pada koperasi https://journal.universitasbumigora.ac.id/index.php/matrik/article/view/474 <p style="text-align: justify;"><em>Cooperatives are usually referred to as a means to help people from low economic circles up to economic conditions upwards.

In addition, also found that game is can help students studies learning the history.</p> Anugerah Bagus Wijaya Suliswaningsih Suliswaningsih Argiyan Dwi Pritama ##submission.copyrightStatement## 2019-11-07 2019-11-07 19 1 196 204 10.30812/matrik.v19i1.496 Analisa Kinerja System Gluster FS pada Proxmox VE untuk Menyediakan High Availability https://journal.universitasbumigora.ac.id/index.php/matrik/article/view/473 <p style="text-align: justify;"><em>Virtualization is used as a means to improve the scalability of existing hardware. Proxmox Virtual Environment (PVE) with hypervisor type based on open source. PVE can use Network Attached Storage as a network-based storage location in GlusterFS storage, which is a distributed file system. The research methodology uses Network Development Live Cycle (NDLC) which has 3 (three) stages, namely analysis, design, and simulation prototyping. The analysis phase is carried out by collecting data by means of literature study and data analysis. The design phase is carried out making the design of network systems and trials. At the simulation stage prototyping tests various scenarios and analyzes Read, Write and Re-Write tests. The system in PVE is integrated with GlusterFS storage made using two servers including the PVE 1 and PVE 2 servers. GlusterFS performance results show that the Read file capability is higher compared to Write, and Re-write in the measurement variations of 1mb, 10mb and 100mb files. In conclusion, GlusterFS can be clustered using the same node as PVE Cluster which can use GlusterFS as additional storage for PVE. GlusterFS also supports live migration features so that LXC or VM can do live migration from one node to another in an online state. The ability to write, re-write and read files on GlusterFS is also relatively stable in testing file size variations.</em></p> Lalu Zazuli Azhar Mardedi Ariyanto Ariyanto ##submission.copyrightStatement## 2019-11-05 2019-11-05 19 1 173 185 10.30812/matrik.v19i1.473
