Understand the effect of selecting the sample size and its effect on the signal recovery process. The experiment utilizes a computer or portable workstation to run an examination of the hypothesis reenactment program. From the test information gotten, it can be concluded that the more noteworthy the frequency of the signal to be inspected, the closer the signal will be to the initial signal. The time and frequency of the examining signal are conversely relative. The higher the frequency, the lower the time will be. The magnitude of the amplitude of the output signal is indeterminate.</p>2020-12-31T00:00:00+07:00Copyright (c) 2020 Journal La Multiapphttps://newinera.com/index.php/JournalLaMultiapp/article/view/277Analog Signal and Digital Signal Processing in Telecommunication System2021-01-14T15:52:58+07:00Phong Hunga.pammuedu@gmail.comVu Duc Vuonga.pammuedu@gmail.com<p>The term digital signal is a term from a technology that converts an analog signal into digital data so that the signal can be processed more easily and quickly. The term digital itself is a system that only recognizes two conditions. The two conditions are usually represented by the numbers zero and one, on and off, or others. The smallest unit of digital signal is the bit.</p>2021-01-31T00:00:00+07:00Copyright (c) 2020 Journal La Multiapphttps://newinera.com/index.php/JournalLaMultiapp/article/view/272Unconventional Technique for Producing Borosilicate Glass Foam2021-01-14T16:14:14+07:00Lucian Paunesculucianpaunescu16@gmail.comMarius Florin Dragoescumar_dmf@yahoo.comSorin Mircea Axintesorinaxinte@yahoo.comFelicia Cosmulescufeliss2014@gmail.com<p><em>The study aims to test an advanced technique but insufficiently valued in the world in the process of experimental manufacture of borosilicate glass foam. It is about the unconventional technique of heating solids by using the microwave radiation converted into heat. The experimental equipment on which the tests were performed was a 0.8-kW microwave oven commonly used in the household with constructive adaptations to be operational at high temperature. The adopted manufacturing recipe was composed of borosilicate glass waste with the addition of calcium carbonate, boric acid and water in different weight proportions. The material was sintered at 829-834 ºC by predominantly direct microwave heating and the optimal foamed product had characteristics similar to those manufactured by conventional techniques (apparent density of 0.33 g/cm3, thermal conductivity of 0.070 W/m•K, compressive strength of 3.1 MPa and a homogeneous microstructure with pore size between 0.7-1.0 mm). The energy efficiency of the unconventional manufacturing process was remarkable, the specific energy consumption being only 0.92 kWh/kg.</em></p>2021-01-14T16:05:40+07:00Copyright (c) 2021 Journal La Multiapphttps://newinera.com/index.php/JournalLaMultiapp/article/view/293Art Building Design Using Byblos Local Value Themes Approach2021-02-06T16:14:16+07:00Aung Ko Tnethatnethko.aung@gmail.com<p>This article discusses the design of an arts building with an approach to the theme of local values. This design is carried out considering the importance of the existence of an art and culture in big cities to boost the local economy and also become an attraction for the tourism sector, as well as the desire of the community to enjoy the beauty of art, as well as the desire of artists to be witnessed and exhibit their works of art. The location that is used as a place for the art building must fill the city spatial planning, where the location of the building that I designed is on Jalan Tanjung Bunga is the central business district, where several supporting facilities such as public transportation, clean water, electricity, telephone network etc., this is the basis for my choosing a location on this flower promontory road. Efforts to increase the attractiveness of the Arts Building by combining traditional Makassar ethnic styles. So that visitors can also find out the typical regional ornaments through this art building. Paying attention to the harmony and balance of design elements in the Arts Building is expected to provide comfort to visitors and organizers of a show.</p>2020-12-31T00:00:00+07:00Copyright (c) 2020 Journal La Multiapphttps://newinera.com/index.php/JournalLaMultiapp/article/view/301Interference Analysis of Medium Voltage Air Line 20 KV Feeder Using Failure Mode and Effects Analysis Method2021-02-06T16:14:13+07:00Yan Min Tunmin.ytun32@gmail.comAung Than Winwinat.thanau@gmail.com<p>This article discusses the interference analysis of medium voltage air line 20 kv feeder using failure mode and effects analysis method. The distribution network consists of two parts, the first the distribution network consists of two parts, the first is the medium / primary voltage (JTM) network, which supplies electrical power from the sub-transmission substation to the distribution substation, the primary distribution network uses three wires or four wires for three phases. the impact of the reliability index from the calculation of the impact of the reliability index based on the number of disturbances (SAIFI), it shows that in January 2019 it has the highest index value, namely SAIFI, 1,695 disturbances/ subscribers. From the results of the calculation of the impact of the reliability index based on the number of blackouts (SAIDI), it shows that in January 2019 the SAIDI index value was 3,883 hours/customer.</p>2020-12-31T00:00:00+07:00Copyright (c) 2020 Journal La Multiapp
