Abstract

Harmony is the key element in producing a piece of music. When a song will be sung by the choir, the song should be arranged in a division of soprano, alto, tenor, and bass voice parts first. Unfortunately, not everyone has the ability to determine the harmonic notes division. There are theories to make a harmonic division of voice parts. Based on the theories, an application for notes arrangement can be developed. The application development uses Application Programming Interface (API) JFugue that can represent music as programming script. Genetic Algorithm is used to implement the application. Chromosome in Genetic Algorithm contains the music notes that have translated into the value of algorithmic music and its duration. Selection is done by giving a reward for the correct notes arrangement and punishment for the wrong notes arrangement. The testing result of this application is already showing a good result. The results of fitness function are in accordance with the verification result from the expert. The average percentage of truth note arrangement is above 98%.

Abstract

Weir is a construction which is used to withstand the rate of water, and ensure water is distributed evenly. In Indonesia there are many weirs are controlled manually. It is less effective because of many human errors, for example in Garut (21/09/2016) and Bekasi (11/20/2014, 04/21/2016). In this study, the automatic weir control system was designed using VDI 2206 design method. Data of water level and flow sensor were processed by a fuzzy logic method to determine the opening of sluice and condition of the weir (safe/danger). Data is displayed on interface based on Microsoft Visual Studio. The test results on the prototype (32x20x18cm) indicate system can work automatically with 99.7% accuracy. The error is affected by ultrasonic sensor error: 5,61% and water flow sensor: 4,83%. Interface show sensor data from microcontroller can be displayed in real time. Benefits of this system are it is easy to control and monitor the weir, water flow is distributed evenly, and provides early warning information to anticipate flooding.

Abstract

Based on UU No. 9 of 1995, Small Enterprises are small-scale people's economic activities and meet the criteria of net worth of at most two hundred million rupiahs or have annual sales of at most one billion rupiahs and own ownership in the form of individual businesses. The government seeks to empower the business world to improve the growth of the business climate, fostering and developing so that small businesses are able to grow and strengthen themselves into strong and independent businesses. The issue that is developing at this time is not optimal data collection of people who have small businesses from the informal business sector due to the form of their business which is individual and not incorporated so that the lack of Regional Original Income can be obtained by the country. Many small businesses take place outside the formal sector from economic transactions formed by the country, but have the potential to increase business service fees. The informal sector refers to small businesses that are managed by individuals or families but are not equipped with adequate business licensing, red zone violations, reluctance in reporting tax obligations, non-compliance with labor regulations that regulate work contract issues, and have no legal guarantees in dealing with suppliers / customer. This research was compiled to create an information system capable of increasing the sources of Regional Original Income, especially those originating from regional retribution in accordance with UU No. 28 of 2009, namely business service fees which are regional levies as payment for special business services provided and / or provided by regional government for the benefit of individuals or legal entity. The using of the Location Based Service method on the software that is built will be able to handle and coordinate information on small businesses in each region so that it can help local governments to manage Regional Original Income specifically Business Services Retribution optimally.

Abstract

In growing industrial era, communication technology through IP network is becoming vital for supporting enterprises productivities. One of high performance communications that is used nowadays is VoIP (Voice over Internet Protocol). VoIP is able to do remote communication without spending high fees. Alongside with high requirements of transmitting and receiving data packet in network, bandwidth management is necessary, so that the decreasing of network performance will not occur. Bandwidth management methods supported by MikroTik RouterOS are HTB (Hierarchical Token Bucket) and PCQ (Per Connection Queue). This research compared HTB and PCQ methods for stabilizing VoIP based on MOS (Mean Opinion Score) parameter and QoS (Quality of Service) parameters such as delay, jitter, throughput, and packet loss using MikroTik devices. In this research, VoIP was tested in MPLS-TE (Multi Protocol Label Switching Traffic Engineering) network. The advantages of TE in MPLS combined with bandwidth management method are maximizing the resources and services in a network and resulting good QoS. The result of this research is that the best QoS and MOS values are from MPLS-TE network using HTB method in normal condition and full bandwidth. In normal condition, the value of delay is 16,02 ms, jitter is 0,00000004 ms, 0% for packet loss, and 146,4 kbps for throughput. When bandwidth is full, delay is 40,567 ms, 0,000000073 ms for jitter, packet loss is 12,667%, and throughput is 58,2 kbps.
