Abstract

ABSTRACT       Department of Transportation, Communication and Information of Manggarai Regency, is one of the instance of Regional Government of Manggarai, NTT, which is responsible to help the Head of Region concerning transportation, communication and information affairs. The lackness of human resources which was competent in computer networking, the high cost of VSAT IP Broadband internet service and maintenance cost of network’s backbone which is wireless based, have been becoming a problem to the Department concerning their main duties. As an impact, it is necessary to the Department to change their network’s backbone to wired network based, using VLAN. VLAN can divide network into several segments with low cost implementation. The using of VLAN Trunking Protocol (VTP) will ease the network administrator in managing VLAN.            The VLAN design in this study used hierarchical model. The logical layer for data distributing was divided into two layers, core/distribution and access layer. Routing between VLANs used “router-on-a-stick using trunk” model, so that the workstations which were owned by different VLAN can communicate each other by using one router only. By using simulation method for testing the design, it was discovered that all workstations between different VLAN have been successfully connected each other and all servers were well-functioned.   Key words : VLAN, VTP,  hierarchical, router-on-a-stick using trunk

Abstract

The average temperature of global warming on the earths surface today has increased by 0.74 ± 0:18°C, the increase was due to the increase in the average temperature of the atmosphere, ocean and land earth. Emissions of the most influential on the quality of the air is carbon emissions, especially carbon dioxide (CO2). The CO2 contributes to global warming is 50%. The CO2 gases absorb and reflect radiation emitted waves of the earth, so that the heat will be stored on the surface of the earth. This study aimed to design a data logger system monitoring the level of concentration of CO2 using the oxygen sensor (OOM202), carbon dioxide sensor (MG81), as well as temperature and humidity sensors (DHT22) with microcontroller-based SMS gateway information. The study tested are simulated in the laboratory with electronic testing and testing communication systems. The test results showed good performance with the prototype, the results of monitoring CO2 emissions seen huge levels of carbon dioxide (ppm) is proportional to the output voltage (Vout) is generated. The greater the concentration levels of gas detected by the sensor, the output voltage generated will be greater, than that difference or distinction ADC output between the measured and calculated because of several errors, such as error output ADC ± 2 bits, error rounding conversion of ADC to volt. The measurement results are different, in the closed and open area refers to the measurement parameters are displayed on an alphanumeric display. Measuring system can transmit data via SMS information system with an average response time of less than 1 minute, it depends on the quality of the signal and traffic data from a provider by the user.

Abstract

Access point berfungsi sebagai pusat pemancar dan penerima sinyal radio pada jaringan nirkabel. Kinerja access point tidak hanya ditentukan oleh spesifikasi perangkat keras dalam access point tersebut, tetapi juga oleh firmware. Firmware bawaan dalam access point TP-LINK TL-MR3020 masih memiliki banyak kekurangan. Kekurangan yang paling mendasar adalah proses identifikasi usb dongle modem yang lama, sekitar 2 hingga 3 menit. Kekurangan lainnya adalah koneksi yang tidak stabil dan panas yang berlebihan. Salah satu solusi mengatasi kekurangan tersebut adalah mengupgrade firmware asli dengan firmware OpenWRT. Penelitian ini bertujuan untuk membandingkan kinerja dan kualitas layanan antara firmware asli dan firmware OpenWRT pada perangkat Access Point TP-LINK MR3020. Pengujian dilakukan dengan cara membandingkan kinerja acces point antara firmware default dan firmware OpenWRT menggunakan parameter througput, delay, jitter, dan packet loss. Dengan hasil pengujian tersebut, dapat diberikan rekomendasi untuk upgrade firmware perangkat access point.Hasil pengujian pada parameter throughput menunjukkan bahwa kualitas bandwidth aktual menggunakan firmware openWRT memiliki kinerja yang lebih baik dibandingkan firmware default dengan selisih rata-rata 26.9%. Sedangkan pada parameter delay diketahui bahwa waktu yang dibutuhkan untuk menempuh jarak dari titik asal ke titik tujuan menggunakan firmware openWRT lebih cepat dibandingkan AP dengan firmware default dengan rata-rata selisih 22.9ms. Pada pengujian parameter Jitter diketahui bahwa variasi kedatangan paket lebih rendah firmware openWRT dibandingkan dengan access point firmware default dengan rata-rata selisih 0.31ms. Pada pengujian parameter packet loss diketahui bahwa jumlah paket yang hilang lebih rendah pada firmware default dibandingkan firmware OpenWRT dengan rata-rata selisih 1.6%. Secara umum dapat disimpulkan bahwa firmware OpenWRT lebih unggul pada parameter throughput, delay, dan jitter, sedangkan firmware default unggul pada parameter packet loss.
