Waste is one of the problems faced by Bogor city, with waste production of 2,701 m3 per day. Waste management of Bogor city currently still has limited garbage facilities and infrastructure that make garbage not yet maximally resolved, including not having a regular schedule of truck distribution in serving sub-district waste. The aim of this research is to optimize the distribution of garbage transport trucks using genetic algorithms. The initial stage of the research carried out is the calculation of the waste generation projection based on population data from Badan Pusat Statistik with reference to SNI 19-3964-1994. Optimization with genetic algorithms consists of a selection process where this study uses the Roulette Wheel selection method, crossover, and mutation. The optimization process using genetic algorithms (GA) from the number of DLH trucks operating currently as many as 60 trucks in serving 490 polling stations (TPS) spread across six sub-districts in Bogor City, the distribution results are to West Bogor district 15 trucks, South Bogor district 13 trucks, East Bogor district 4 trucks, Central Bogor district 3 trucks, North Bogor 12 trucks, and 13 trucks for Tanah Sareal district. Optimization testing with GA showed that with 60 dump truck type trucks with a capacity of 7 m3 operating and transporting as many as 3 rit, the garbage transported is only about 46.64% of the total waste. To achieve the government's target regarding solid waste services of 80 until 85%, 110 trucks are needed. Keywords : genetic algorithm, optimization, scheduling

Web server clusters require a reliable network management for increasing the quality of service (QoS). A load balancer system installed in a software-defined network (SDN) is one method that can improve the performance and availability of web server services. SDN is a dynamic and a programmable network management approach, and one protocol that supports it is OpenFlow. This research aims to design and analyse a model of a load balancer on OpenFlow networks, implementing a Weighted Round Robin (WRR) algorithm. The analysis process is conducted by measuring the value of a QoS web server performance parameters, such as response time, throughput, HTTP success, and loss connection. The results showed the WRR algorithm can be implemented for balancing a network system with dynamic resource allocation. The weight workload of each service can be obtained from the needs and existing network resources. The performance of a load balancer on an OpenFlow network is 57% better than in a traditional one for testing of response time conducted in a high connection. However, the throughput and HTTP success connection decreased by 2% and 10%, respectively, while HTTP loss connection increased by 49%.

Kegiatan mempersiapkan slide presentasi oleh dosen pada setiap awal pertemuan kuliah akan mengurangi efektifitas waktu belajar. Penelitian sebelumnya memiliki kekurangan dalam penerapannya karena membutuhkan biaya yang besar untuk penyediaan komputer di setiap kelas dan peletakan berkas yang bersifat lokal. Salah satu solusi untuk mengatasinya adalah dengan mengganti komputer desktop biasa dengan single board computer (SBC), Raspberry Pi. Penelitian ini bertujuan untuk merancang dan membangun sistem otomasi presentasi kuliah dengan radio frequency identification (RFID) sebagai pembawa id untuk diteruskan ke Raspberry Pi yang akan mengirimkan query sesuai dengan id yang dibaca ke server database. Apabila id terdaftar dan sesuai jadwal yang ada, Raspberry Pi akan mengirimkan query ke server FTP untuk mengunduh slide presentasi yang relevan. Selanjutnya, Raspberry Pi akan menampilkannya melalui proyektor. Seluruh sistem bekerja dengan baik dalam empat skenario pengujian, yaitu: pengujian pembacaan tag, pengujian posisi tag, pengujian akurasi, dan pengujian waktu. Hasil pengujian waktu menunjukkan bahwa sistem dapat menampilkan slide kuliah dalam waktu rata-rata 60.145 detik. Hal ini dapat menghemat waktu kegiatan perkuliahan sehingga berjalan lebih efektif. Kata kunci: otomasi presentasi, Raspberry Pi, RFID, server FTP

Vehicular Ad-Hoc Network (VANET) merupakan pengembangan jaringan wiresless yang melakukan komunikasi secara Inter Vehicle Communication (IVC). VANET memiliki mobilitas yang tinggi untuk setiap node nya sehingga jaringan komunikasi jenis ini adalah jaringan yang bersifat sementara dikarenakan node bergerak di lintasan dengan arah dan kecepatan yang dinamis. Dengan demikian, pengiriman paket data dari node sumber ke node tujuan menggunakan VANET memerlukan beberapa teknik komunikasi. Teknik terbaru komunikasi VANET saat ini adalah menggunakan SDN (Software Defined Network) yang berbasis geographic (SDGR) sebagai control plane dalam mengontrol komunikasi ad-hoc antar node. Dalam membentuk topologi jaringan komunikasi, SDGR mencari nilai jalur terpendek antar node dan kepadatan node yang tinggi. Tujuan utama penelitian ini melakukan analisis konsep protokol perutean (routing protocol) SDGR dan dilakukan pengembangannya dengan mempertimbangkan arah rute (SDGR+R). Pada SDGR+R, penambahan basis arah rute menggunakan multicast. Selanjutnya, dilakukan perbandingan kinerja antara SDGR dan SDGR+R. Hasil simulasi menunjukkan SDGR+R memiliki kinerja lebih baik daripada SDGR dalam hal latency sebesar 1.88% dan packet delivery ratio (PDR) sebesar 8.12%. Perancangan protokol perutean SDGR+R menambah ide pengembangan teknologi pada VANET untuk masa mendatang. AbstractVehicular Ad-Hoc Network (VANET) is a wireless network developed for communication on Inter-Vehicle Communication (IVC). Each node in a VANET has high mobility so that this type of communication network is a temporary network because the node moves on the track with dynamic direction and speed. Thus, sending data packets from source node to destination node using VANET requires some communication techniques. The latest technology for VANET communication is to use SDN-based geographic-based SDN (SDGR) as a control plane in controlling Ad-hoc communication between nodes. In forming the communication network topology, SDGR looks for the shortest path value between nodes and high node density. The main objective of this research is to analyze the concept of SDGR routing protocol and to develop it, considering the direction of the route (SDGR+R). In SDGR + R, the addition of route base directions uses multicast. Next, we compare the performance between SDGR and SDGR+R. Simulation results show SDGR+R has better performance than SDGR in terms of latency of 1.88% and packet delivery ratio of 8.12%. The design of the SDGR+R routing protocol gives to the idea of technology development on VANET in the future.

The technical problems faced in e-government implemented by the Ministry of Religion of Indonesia since 2015 are minimal bandwidth requirements to provide information services and behavior of users who access entertainment sites. When peak hours occur, the congested network often occurs which becomes a significant bottleneck. This study aims to implement bandwidth management using the fractional knapsack problem method by limiting access to entertainment services. The QoS parameters used in this management are throughput, delay, and jitter. The method was tested using a paired t-test using throughput, jitter, and delay test parameters by comparing test parameters before and after bandwidth management applied. The significance value produced is between 75-85%. The method used can control the amount of traffic for each service, but on the other, hand the delay and jitter are still high. It is necessary to add additional free space to each service that can be used when needed to reduce the delay and jitter.
