Published: May 2020

The high reliability of data access has become a problem faced by many companies, institutions, and universities. For this reason, a protocol required that can protect the network from a communication breakdown. One method used to maintain communication is by implementing a protocol redundancy system.  One or more routers will act as the primary router for load balancing, and some routers are in standby mode if one main router is down. First hop redundancy protocols (FHRP) is a protocol that implements redundancy and load balancing systems. This protocol can transfer access data traffic if one of the routers on the network is down. FHRP divided into virtual router redundancy protocol (VRRP) and gateway load balancing Protocol (GLBP). This research analyzes the design and implementation to provide information about the quality of VRRP and GLBP services on the main router and the backup router, by using an application graphical network simulator (GNS) simulation 3. In the GNS3 application, a LAN network topology is designed with eight router devices in the form of a ring topology using RIPv2 and OSPF routing protocols, then implemented in protocols VRRP and GLBP. The analysis results show that GLBP can back up the network faster than VRRP when the primary router is down. If implemented into a LAN network with RIPv2 and OSPF routing protocols, VRRP has better service quality than GLBP.

Published: May 2020

Wireless sensor networks (WSNs) are small devices that are run by batteries as minimal energy resources. The cluster method is one of the ways on WSN that is widely applied to the routing protocols to extend the network's lifespan. Low-Energy Adaptive Clustering Hierarchy (LEACH) is a cluster-based protocol proven to increase energy efficiency in sensor networks. However, LEACH also has disadvantages such as a selection of cluster heads that don't consider residual energy at every node. It is the cause of failure in the election process and affects the stability of the network cluster. Period network stability is essential as reliable feedback from a network. Therefore, this study tries to investigate and solve stability problems in the LEACH algorithm. In this paper, the authors propose a new protocol that is Optimization-LEACH (O-LEACH), which is the development of the LEACH protocol. The O-LEACH protocol cluster-head selection process is developed based on the initial energy of each node, and a new beginning energy levels calculated from each node to every round. The test results show that the proposed O-LEACH protocol has a better stability period and network lifetime than the LEACH protocol.

Published: May 2020

Data scaling has an important role in preprocessing data that has an impact on the performance of machine learning algorithms. This study aims to analyze the effect of min-max normalization techniques and standardization (zero-mean normalization) on the performance of machine learning algorithms. The stages carried out in this study included data normalization on the data of leaf venation features. The results of the normalized dataset, then tested to four machine learning algorithms include KNN, Naïve Bayesian, ANN, SVM with RBF kernels and linear kernels. The analysis was carried out on the results of model evaluations using 10-fold cross-validation, and validation using test data. The results obtained show that Naïve Bayesian has the most stable performance against the use of min-max normalization techniques as well as standardization. The KNN algorithm is quite stable compared to SVM and ANN. However, the combination of the min-max normalization technique with SVM that uses the RBF kernel can provide the best performance results. On the other hand, SVM with a linear kernel, the best performance is obtained when applying standardization techniques (zero-mean normalization). While the ANN algorithm, it is necessary to do a number of trials to find out the best data normalization techniques that match the algorithm.

The carelessly selection of specialization course leaves some students with difficulty. Therefore, it is needed a recommendation system to solve it. Several approaches could be used to build the system, one of them was K-Means. K-Means required the number of initial centroid at random, so its result was not yet optimal. To determine the optimal initial centroid, Density Canopy (DC) algorithms had been proposed. In this research, DC and K-Means (DCKM) was implemented to build the recommendation system in the problem. The alpha criterion was also proposed to improve the performance of DCKM. The academic quality dataset in the 2018 informatics programs students of ITTP was used. There were three main stages in the system, namely determination of the weight of the course in dataset, implementation of DCKM, and determination of specialization recommendations. The results showed that the system by using DCKM has good quality based on the Silhouette results (at least 0.655). The system also used standar valuation scale in ITTP and silhouette index in the process of system. The results showed that 176 (65.91%) students were recommended in IT specialization, 25 (9.36%) students were recommended in MM specialization and 66 (24.7%) students were recommended in SC specialization.

Indonesia memiliki berbagai jenis pisang tanduk dengan karakteristik yang berbeda. Informasi mengenai perbedaan karakteristik dan daya simpan beberapa jenis pisang tanduk masih sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik dan daya simpan empat aksesi pisang tanduk. Penelitian ini dilaksanakan di Laboratorium Pascapanen, Departemen Agronomi dan Hortikultura, Institut Pertanian Bogor, Darmaga, Bogor, Jawa Barat pada bulan Maret 2017 hingga Juni 2017. Bahan utama yang digunakan yaitu 4 aksesi pisang tanduk yang berada di Kecamatan Dramaga, Kabupaten Bogor, Jawa Barat. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu aksesi. Faktor aksesi terdiri atas 4 aksesi dan 4 ulangan. Hasil penelitian ini menunjukkan bahwa aksesi memberikan pengaruh nyata terhadap semua karakter yang diamati (bobot buah, panjang buah, diameter buah, ketebalan kulit, bobot daging, bobot kulit, kelunakan, BDD, PTT dan ATT) kecuali rasio antara PTT/ATT. Aksesi 1 dan 3 memiliki kualitas fisik (bobot buah, panjang, diameter dan ketebalan kulit) terbaik. Kualitas kimia terbaik terdapat pada Aksesi 3. Susut bobot Aksesi 1 dan 3 merupakan susut bobot terendah dibandingkan Aksesi lainnya. Hasil pengujian aktivitas antioksidan menunjukkan bahwa aktivitas antioksidan pada semua aksesi tidak aktif. Umur simpan pisang berkisar antara 15 hari sampai dengan hari.

Pengamatan terhadap manajemen panen dilaksanakan di KebunAdolina, Sumatera Utara pada tanggal 5 Februari 2018 sampai 30 Juni 2018terdiri organisasi panen,perencanaan panen, pelaksanaan panen, pengawasan dan evaluasi panen. Secara khusus efisensipengangkutan diamati dengan membandingkan teknis dan waktu muat buah pada hanca. Hasil pengamatanterkait manajemen panen seperti rotasi panen, estimasi dan realisasi dari angka kerapatan panen, jumlahtenaga kerja, kriteria matang panen mengalami deviasi dari standar prosedur operasional (SPO) perusahaan.Hal ini dilakukan untuk mencapai target produksi bulanan saat kerapatan buah menurun akibat pencurian. Dikebun tidak ditemukan adanya losses berupa buah matang tidak dipanen setelah ada perubahan sistem hanca.Selain itu terdapat perbedaan tingkat kepatuhan pemanen pada tanaman yang menggunakan sistem tanamstandar dan big hole. Hasil pengamatan terkait efisiensi pengangkutan menunjukkan adanya perbedaan teknisdan waktu yang nyata antara cara pengangkutan menggunakan jembatan atau tidak.
