Abstract

Tulisan ini membahas karya komposisi musik yang berjudul “Tungkal Hilir-Hulu” dengan pengkarya Sopiyan (penulis), yang dipergelarkan pada tanggal 11 januari 2017 di Gedung Auditorium Boestanoel Arifin Adam ISI Padangpanjang. Karya ini terinspirasi dari kesenian kelintang tungkal, yaitu pada teknik pengulangan hilir dan hulu, ritme dasar dari serame, begubang, dan tupai begelut menjadi media garap dengan menggunakan pendekatan garap tradisi. Dalam hal ini pengkarya menciptakan kembali bentuk musikal yang baru dari teknik hilir dan hulu serta laras yang mendekati Bes-C-D-Dis-G-Bes1-C1 ke dalam bentuk karya komposisi musik karawitan yang masih memakai idiom-idiom tradisi dalam penggarapannya. Metode tradisi kekaryaan antara lain: obsevasi, eksplorasi, penyusunan, dan perwujudan. Karya komposisi ini dibagi menjadi tiga bagian yaitu (1) Pertama : pengkarya memfokuskan pada pengarapan teknik hilir dengan menghadirkan ritme dasar dari serame, begubang, dan tupai begelut. Ritme dasar dimainkan hingga membetuk formulasi melodi yang baru. (2) bagian keduapengkarya memfokuskan garapan pada penggarapan teknik hulu dengan tempo yang tidak terikat. Bagian ini didominasi oleh instrumen melodis. (3) bagian ini pengkarya menggabungkan teknik hilir dan hulu yang digarap secara bersilang. Pengkarya juga memasukan ornamentasi berbentuk garapan vokal. This writing discusses about music composition entitled “Tungkal Hilir-Hulu” composed by Sopiyan (writer) and performed on January 11th 2017 in Hoeridjah Adam Performance Building of ISI Padangpanjang. This composition is inspired from kelintang tungkal art, namely in hilir and hulu repetition technique, basic rhythm of serame, begubang, and tupai begelut become composition media by using traditional composition approach. In this matter, composer recreates new musical form of hilir and hulu technique and harmony that approaches Bes-C-DDis-G-Bes1-C1 into karawitan composition music that still uses traditional idioms in its composition. Method of compositional tradition consists of observation, exploration, arrangement, and materialization. This composition is divided into three parts namely (1) first, composer focuses on the composition of hilir technique by bring out basic rhythm of serame, begubang, and tupai begelut; basic rhythm is played until it forms new melody formulation; (2) second part, composer focuses his composition on the composition of hulu technique with unbound tempo; this part is dominated by melodious instrument; (3) in this part, composer combines hilir and hulu techniques that are composed alternately. Composer also inserts ornamentation in the form of vocal composition.

Abstract

Hardness is a mechanical property that is needed when doing the hardfacing process. Increased violence can be generated by conducting a quenching process. The temperature of the quenching media is one of the important factors to produce maximum hardness. In this study a two-layer welding process will be carried out using HV 350 electrodes on low carbon steel then the specimens are heated in a furnace and quenching is carried out into water with two variations in water temperature namely 15 and 30 °C. Variations in water temperature during quenching produce varying hardness and microstructure. The highest hardness is produced at 15 °C where in micro photographs there are a few phases of smaller size compared to other specimens.

Abstract

The scarcity of fuel oil energy has led to the development of research on additional and alternative energy sources for fuel. one of the alternatives that can be utilised from the large amount of plastic waste scattered in the environment becomes environmental pollution. Is the processing of plastic waste so that it can be processed into fuel oil solutions. Tools for processing plastic waste into fuel oil using the pyrolysis process. Further research is needed regarding the design of pyrolysis equipment. This research uses computational methods by testing on computer devices using CAE software, namely Solidwork, inventor and Ansys and then testing also uses experimental methods and computational 3-dimensional analysis to obtain a suitable design to produce pyrolysis compressors which include thermal and structural testing. The pyrolysis device of waste plastic into fuel oil has the highest temperature at the combustion surface of 500.47 ℃ and the temperature is stable at 143.95 ℃. the temperature inside the plastic combustion reactor is at 489.23 ℃. the cooling water temperature of 24 ℃ can LMTD value of 83.6 ℃. raw material of 10 kg LDPE produces liquid smoke from the weight of plastic which is 7.04 kg with a volume of 6.56 litres in one process. Dimensional strength and tool strength are used in the design of pyrolysis equipment with materials including stainless steel 304 and 316 then monel and copper can experience a maximum total heat flux change of 12.261 W/mm2 and has a safety factor value of 15. from Plastic waste can be processed and utilised into fuel oil. One type of plastic that can be utilised is LDPE waste using the pyrolysis process using appropriate calculations in the study.

Abstract

Smart Guard Home is a design for security, safety, comfort and prevention for humans. Internet of Think-Based Smart Guard Home which the author designed uses an interconnected Microcontroller and Sensor which is then sent over the network to a PHP (Hypertext Preprocessor) Web server which is responsible for sending data via the HTTP (Hypertext Transfer Protocol) protocol and running scripts. Appropriate PHP. PHP scripts are used to process requests, access databases, and generate dynamic content which will be sent to the Database which is then sent back to the client. The author uses the hosting MySql Database which is then accessed using CPanel and managed using PHP Scrip and sent via the internet to the Android application. Mobile and web applications are Android UI/UX-based applications for real-time monitoring and notifications that can be accessed anywhere and anytime via the internet network.
