Abstract

The increasing development of the Internet today is in line with the complexity of on line on the internet. So the Network flow optimization became the main problems related to the election of the shortest route (routing protocol). Focus on research is to find out and compare the process with the shortest route in the search algorithm is Greedy algorithm and A * in order to reduce the workload of the network. Model comparison algorithm that is done is look at the workings of each algorithm against the determination of the routing path from the sender to the receiver. On the basis of the implementation of the experiment it was found that the algorithm a * greedy algorithm finds its way with the same. but it is clear for the a * would be more effective if applied on a broad network as well as complicated. Because the calculation uses a * definite while greedy simply looked at what is the most short front side towards the next node that was selected when the end result can be greater than the calculation of a

Abstract

Pada masa modern seperti ini kebutuhan akan internet semakin meningkat tajam, baik itu untuk bekerja mengolah data dan hiburan. Untuk membangun infrastruktur jaringan yang baik tentunya dibutuhkan penanganan yang tepat sesuai dengan kondisi di lapangan. Dalam penelitian ini kami mengangkat tema penerapan metode HTB yang akan diimplementasikan dalam jaringan RT/RW Net di Farid.net. Dalam analisa jaringan ini terdapat suatu masalah, setelah pengelompokan data dari pelanggan dimana terdapat keluhan tentang bandwidth yang didapat tidak sesuai dengan paket yang dipilih, sehingga hal tersebut menimbulkan ketidaknyamanan pengguna. Untuk mengatasi masalah tersebut kami mendapatkan solusi dengan menerapkan metode HTB. Cara kerja dari metode ini sendiri, membagi bandwidth kedalam beberapa kelas, yang mana terdapat dua kelas utama yaitu parent dan child, metode ini memungkinkan administrator untuk membagi bandwidth berdasarkan besar bandwidth yang diminta pelanggan. Dari penerapan metode HTB dapat diambil kesimpulan bahwa bandwidth yang didapat antar user menjadi lebih stabil dan merata, hal tersebut dapat dibuktikan dengan melalui Speedtest dan pemantauan traffic. Selain itu konektivitas jaringan pun juga lebih stabil dikarenakan bandwidth dari client sudah terkontrol.Kata Kunci — bandwidth, Hierarchical Token bandwidth, HTB.In modern times like this the need for the internet is increasing sharply, both for working on data processing and entertainment. To build a good network infrastructure, of course, proper handling is needed according to the conditions in the field. In this study we raise the theme of applying the HTB method which will be implemented in the RT / RW Net network at Farid.net. In this network analysis there is a problem, after grouping data from customers where there are complaints about the bandwidth obtained that is not in accordance with the package chosen, so that it causes user inconvenience. To overcome this problem, we got a solution by applying the HTB method. The workings of this method itself, dividing bandwidth into several classes, where there are two main classes, namely parent and child, this method allows the administrator to divide the bandwidth based on the bandwidth requested by the customer. From the application of the HTB method, it can be concluded that the bandwidth obtained between users becomes more stable and equitable, this can be proven by Speedtest and traffic monitoring. In addition, network connectivity is also more stable because the bandwidth of the client is controlled.Keywords — bandwidth, Hierarchical Token bandwidth, HTB.

Abstract

Lake Lindu is located in conservation area, the Lore Kalamanta National Park, and still on natural condition. Therefore, it is interesting to recognize their biological condition, especially zooplankton existence. It was observed the zooplankton spatial distribution on March 2001 and evaluated the factors which influenced to their abundance. Four sampling station at rivers, inlet of the lake, five in lake waters body at 0 m; 3 m , 5 m, and 10 m water depth were studied. Supporting data, namely organic content on COD(Chemical Oxygen Demand) parameter was measured on same location, for a while phytoplankton and heterotrophyc bacteria data from secondary data. There were five genus zooplankton, namely Ceriodaphnia (Cladocera), Diaptomus, Cyclops (Copepoda), Brachionus and Filinia (Rotifera). It was not found zooplankton at rivers, therefore average of abundance in lake water body ranged 37 - 376 ind.l-1, and based of depth stratum their abundance show to maximize at three meters depth. Zooplankton abundance seem correlate support factors quadratically, positively to COD and abundance of heterothrophyc bacteria, but negatively to phytoplankton abundance.

Abstract

Electrical energy is a primary need at this time, which almost all human activities require electricity. The electrical energy we use today is a conversion from other energy, partly derived from fossil energy, which is energy that cannot be renewed and will run out if it is continuously explored and exploited. Solar energy is a renewable energy source that has the potential to be converted to electrical energy using solar panels or so-called photovoltaics. Photovoltaic has a drawback in its use, namely the output value is very dependent on environmental conditions. To maximize the power efficiency between the photovoltaic output and the power to be used by the load, a method is needed, namely Maximum Power Point Tracking (MPPT). In the application of this MPPT DC-DC Zeta converter is used with a hill climbing algorithm to achieve the value of the output voltage and current at maximum power. With this method, it is expected that MPPT control is reliable and easy to apply. In this study, the type of photovoltaic module used is the 60 Wp monocrystalline type with sampling data once an hour from 09.00 - 17.00 WITA, the tracking speed data obtained by the modified hill climbing algorithm is 0.142 seconds on average with an average efficiency of 99.969 %.
