This research develops and implements a method for calculating lighting systems for classrooms at Khairul Ummah Islamic Boarding School. The lumen method is one of the methods used to determine the number of luminaires needed to improve lighting quality according to the SNI 6197: 2011 standard. The number of luminaires obtained in this study was included in the simulation for DIALux evo 8.1 software. The results obtained from this study show that the lighting in the classrooms at MTs and MA Khairul Ummah Islamic Boarding School has not reached the recommended standard for classrooms, where the direct measurement results of the average lighting level of class IX-E is 10.79 lux, while in the class X IPA 3 is 11.66 lux. To improve this condition, class IX-E requires the number of luminaires of 15 points and class X IPA 3 requires a luminaire of 12 points. The difference in results obtained from mathematical calculations using the lumen method and the simulation results of DIALux software for class IX-E is 15.6% and in class X IPA 3 is 3.4%. The value of investment costs is necessary in order to make improvements to the lighting system in these two schools which are worth Rp. 2,700,000.00 to provide 27 Philips LED bulb 27 watt lamps.Keywords: Classroom, DIALux evo 8.1, Investmen Cost, Lighting, Lumen Method

This study is aimed to design and analyze bidirectional converter three phase by using method SPWM on electric bike. This study discusses the three-phase inverter with Sine Pulse WidthModulation (SPWM) method as a three-phase induction motor drive and also the rectifier which has function to convert the AC voltage of the source of three-phase AC into DC voltage that ismodeled by using Matlab / Simulink. The purpose of this study is to get the design of the threephase inverter SPWM as a three-phase induction motor drive 500 W, 30 V, and 50 Hz. Theinverter design using battery voltage 48 V. Besides that to getting rectifier mode design that is aimed to fill a 48 Volt DC battery that is a driving source an induction machine when that isnot driven from PLN. The results of the analysis inverter mode performed on the motor no-load conditions (zero load). Through simulation with Matlab software is then obtained curve ofsinusoidal voltage box 48 Volt, current 2,5 Ampere, and speed of the motor by SPWM controlled system. Then, the simulation results in rectifier mode is done with Matlab software value obtained 52.03 Volt battery charging voltage and battery charging current is 7.977 Amperes.Keyword : Three Phase Inverter, Sine Pulse Width Modulation (SPWM), Three Phase Induction Motor, Matlab/ Simulink, Electric bike, Rectifier.

Harmonics cause voltage distortion that can result in electrical equipment becomes hot quickly, the power factor is low, interference with the equipment that use relays for switching and measurement accuracy kWh-meter induction type will be reduced, therefore harmonics requires serious attention, to cope with a wave distorted would require a technology that has the function of fixing the waves, this technology is called filter. The use of filters to reduce harmonic been widely recommended to overcome these problems. This final project describes one harmonic filter configuration, that’s called Active Filter parallel configuration, the method used is Cascaded Multilevel Inverter. The results of the simulation system design and form of the value of THD (Total Harmonic Distortion). THD value on systems that use an active filter Cascaded Multilevel Inverter showed a significant decrease compared to the system without the addition of a filter on Bidirectional Hybrid Inverter 1500 watts.Key Word: Harmonic, Active Filter, Cascaded Multilevel Inverter

Improving the quality of human resources is the main supporting factor in increasing national productivity in various fields and development sectors. The government's productive investment activities that spur the nation's competitiveness in the global era prioritize Indonesia's education development. This study aims to cluster provinces in Indonesia based on educational indicators using the Agglomerative method consisting of the Average Linkage and Ward methods. Data collection is based on documentation techniques obtained from Statistics Indonesia in 2018. Data analysis used hierarchical cluster analysis consisting of data standardization, determining the size of the similarity or dissimilarity between data, the clustering process with a distance matrix, and seeing the characteristics of the cluster results formed. The second clustering method is by doing the initial grouping and determining the excellent cluster based on the average standard deviation ratio to the standard deviation between groups. Clustering results show the Ward method with the number of collections as many as 4 clusters and produces a ratio with a value of 0.01 smaller than the Average Linkage method. It shows that the cluster analysis method using the Ward method has better group accuracy quality than the Average Linkage method.

Salah satu jenis data penting yang digunakan di dalam analisis empirik adalah data runtun waktu.Dalam meregresikan suatu variabel runtun waktu pada satu(beberapa) variabel runtun waktu yanglain, orang sering memperoleh nilai R2 yang sangat tinggi meskipun tidak terdapat hubungan yangberarti antara kedua variabel tersebut. Terkadang kita menyangka tidak ada hubungan antara keduavariabel, namun regresi satu variabel pada variabel yang lain sering menunjukkan hubungan yangsignifikan. Situasi ini memberikan contoh persoalan regresi lancung. Persoalan regresi lancung bisamuncul dari meregresikan suatu variabel runtun waktu nonstasioner pada satu atau lebih variabelruntun waktu nonstasioner. Oleh karena itu, penting untuk bisa menentukan apakah data runtunwaktu stasioner atau tidak. Suatu data runtun waktu disebut stasioner jika ia tidak memuat akarakarunit. Sebuah uji stasioner (atau nonstasioner) menjadi sangat populer sejak dua dekade terakhiradalah uji akar-akar unit. Makalah ini dimaksudkan untuk menjelaskan bagaimana menggunakan ujiakar-akar unit di dalam model runtun waktu khususnya untuk model runtun waktu autoregresif.

The popularity of the local Javanese music “Dangdut Campursari” increased dramatically from 2019 to 2020. Didi Kempot, who is nicknamed the God Father of Broken Heart, is a new phenomenon in Javanese music in the country. This research wants to see how the modern Campursari dangdut lovers “Sobat Ambyar” describe the identity of their community and see this phenomenon from the perspective of popular culture which includes trends, adaptability, and pop music consumerism. We documented Sobat Ambyar’s chat on social media, they managed and conducted in-depth interviews with the Instagram fanbase admin @sobatambyar. The results of this study indicated that Sobat Ambyar identifies themselves with the feelings, attitudes, and emotions of the songs sung by Didi Kempot. These identities tend to be sad and they are proud of that sadness. This Campursari has become a new commodity for industry and is popularized through the ways of modern culture which is simulated and marketed. Based on these findings, this study suggests that Sobat Ambyar remain authentic so that they can block mass culture that the younger generation is not aware of.Keyword : Fans, Instagram, Modern Campursari Music, Sobat Ambyar.
