The objective of this research is to make a constant pressure control in water supply with the method of PID using PLC Siemens S7-1200 as a controller and also to monitor the process of its work system from a distance through the internet of things (IoT). The water distribution system is created utilizing 3 phase pump which will supply water from the tank. The pressure sensor will be used as an analog input signal of PLC to detect the pressure of water in the pipe. Using inverter, water pressure will be kept constantly matched with the desired set point through the setting of pump speed using the digital PID method that is available on PLC. The score of the set point is done through HMI of touch panel KTP700basic. By using Wi-Fi communication that has been connected to the internet, PLC data can be sent to a cloud server through raspberry pi3 using the MQTT protocol. Raspberry pi3 program is designed using the java script coding language. Research result showing that this system can keep the water pressure at a constant level of 1.2 bar in the water supply. It is also able to monitor the water pressure through HMI and handphone via IoT Technology in the GoIoT server.
Brush-less Direct Current (BLDC) motor drive systems are widely used in electric vehicles (EV). However, most EV control strategies only focus on BLDC motors without considering changes in different driving conditions. This paper proposes an intelligent control strategy based on an intelligent neural network that can change control parameters based on changing driving conditions. This system has the ability to self-learning and adapt based on driving conditions. The simulation is carried out using the Electric Vehicle Drive Train model and run on the MATLAB-SIMULINK platform. The simulation results show that the smart control strategy designed shows very good efficiency with minimal errors and quickly adapts to different driving conditions.
The purpose of this study was to determine the effect of the intensity of group learning activities and student motivation on learning outcomes in the electrical lighting installation subjects of class XI students at 34 State Vocational Schools in Jakarta. The method used in this study is a survey with a causal approach and research subjects (respondents) are not manipulated or given special treatment by researchers. The results of the research with a causal approach are analyzed using path analysis with a significance level of 5%. Results research shows that the path coefficient value (ρ31) amounting to 0.170, with thitung = 3,088 and ttabel = 1,6716 on α = 0,05, That mean significant path coefficient because of value thitung> ttabel atau 3,088> 1,6716. Thus, from these findings it can be interpreted that learning motivation (X2) has a direct effect on learning outcomes (X3) of 16.32%. Value of path coefficient (ρ31) amounting to 0.170, with thitung = 1,206 And ttabel = 1,6716 on α = 0,05, that mean path coefficient value is not significant because the value of thitung <ttable or 1.206 <1.671. Thus, from these findings it can be interpreted that the intensity of group learning activities (X1) does not directly influence learning outcomes (X3) and indirectly influence learning motivation (X2) on learning outcomes of 3.67%. Abstrak Tujuan penelitian ini adalah untuk mengetahui pengaruh antara intensitas kegiatan belajar kelompok dan motivasi beajar terhadap hasil belajar pada mata pelajaran instalasi penerangan listrik siswa kelas XI di SMK Negeri 34 Jakarta. Metode yang digunakan dalam penelitian ini adalah survey dengan pendekatan kausal dan subjek penelitian (responden) tidak dimanipulasi atau diberikan perlakuan khusus oleh peneliti.Hasil penelitian dengan pendekatan kausal tersebut dianalisismenggunakan analisis jalur (path analysis) dengan tingkat signifikansi sebesar 5%. Hasil penelitian menunjukan bahwa nilai koefisien jalur (ρ32) sebesar 0,404dengan thitung = 3,088dan nilai ttabel = 1,6716 pada α = 0,05, artinya koefisien jalur signifikan karena nilai thitung> ttabel atau 3,088> 1,6716. Dengan demikian, dari temuan ini dapat ditafsirkan bahwa motivasi belajar (X2) berpengaruh langsung dengan hasil belajar (X3) sebesar 16,32%.Nilai koefisien jalur (ρ31) sebesar 0,170, dengan thitung = 1,206 dan nilai ttabel = 1,6716 pada α = 0,05, artinya nilai koefisien jalur tidak signifikan karena nilai thitung<ttabel atau1,206< 1,671. Dengan demikian, dari temuan ini dapat ditafsirkan bahwa intensitas kegiatan belajar kelompok (X1) tidak berpengaruh langsung terhadap hasil belajar (X3) dan berpengaruh secara tidak langsung melalui motivasi belajar (X2) terhadap hasil belajar sebesar 3,67%.
Research of this thesis examines the feasibility of electrical installations on residential houses in RW 02, Kelurahan Kayu Manis Kecamatan Matraman with a power of 900 VA-2200 VA and the age of the electrical installation of more than 15 years. Refers to the standard installation of Airworthiness Requirements General Installation listri (PUIL) for housing. Collecting data by observation, documentation and measurement. Observations made on safety equipment and electrical installations to determine the quality of the electrical installation. Measurement of insulation resistance, grounding prisoners and cable cross-section to find out the quality of work of installation fixtures attached. It can be said that in the terms of Electricity installation the feasibility, RW 02 Kelurahan Kayu Manis Kecamatan Matraman Jakarta Timur can be said to be not in accordance with the provisions of PUIL 2011. Given prisoners grounding can’t be measured. ABSTRAK Riset skripsi ini meneliti tentang kelaikan instalasi listrik pada rumah tinggal sederhana di RW 02 Kelurahan Kayu Manis Kecamatan Matraman dengan daya 900 VA-2200 VA dan usia instalasi listrik lebih dari 15 tahun. Kelaikan instalasi mengacu pada standar Persayaratan Umum Instalasi Listri (PUIL) untuk rumah tinggal. Pengambilan data dengan cara observasi, dokumentasi dan pengukuran. Observasi dilakukan pada perlengkapan dan pengaman instalasi listrik untuk mengetahui kualitas instalasi listrik. Pengukuran tahanan isolasi, tahanan pembumian dan penampang kabel untuk mengetahui kualitas kerja dari perlengkapan instalasi yang terpasang. Dalam segi kelaikan instalasi listrik di RW 02 Kelurahan Kayu Manis Kecamatan Matraman Jakarta Timur dapat dikatakan tidak sesuai dengan ketentuan PUIL 2011. Mengingat tahanan pembumian yang tidak dapat diukur.
