Furthermore, data collected by the questionnaire and test. Test validity and reliability for the question form is done with a technique Pearson Correlation coefficient obtained 0.88 and coefficient value of Cronbach's Alpha is 0.892. The results of this research are showed that: 1) the basic electronics learning modules based on problem solving that developed in its entirety was declared eligible for use, with the result average of validation of material categories include very decent, and the result average of validation of media categories include very decent too. The readability is included in category of very decent and in terms of learning to use the modules is included in the category of very decent. Using modules in the learning process are known there is increasing with the average value of the students learning outcomes of 68.53 rises to 80.24. T-test analysis results known tcalculate = 11.76 and ttable = 1.69 which means that the student learning outcomes has a significant improvement

This study aims to develop and determine the feasibility of E-Module learning media in Electromechanical Work Basic Subjects. This research is a development research using ADDIE model. The product developed is emodule learning media on subjects in Electromechanical Basic Work. Data collection is done by means of observation, interviews and questionnaires.

Pintu merupakan sebuah media yang digunakan sebagai jalan untuk masuk atau keluar dari ruangan. Untuk mempermudah suatu pekerjaan dibutuhkan suatu alat yang efektif dan efisien. Pintu konvensional biasanya terdiri dari rumahan kunci dan sadel kunci untuk membukanya. Umumnya di perkantoran pintu dapat dibuat dengan lebih praktis. Pintu akan otomatis terbuka jika ada stimulus (energi fisik) yang menggerakkannya. Misalnya ketika seseorang hendak masuk ke dalam ruangan maka pintu akan otomatis terbuka. Pintu seperti ini dapat dirancang dengan menggunakan kendali otomatis. Sistem pintu otomatis ini dapat dirancang dengan menggunakan kendali otomatis yang dipadu dengan sensor dan motor. Dari segi peralatan input digunakan sensor PIR (Passive Infrared) yang dapat mendeteksi adanya manusia yang akan mendekati pintu. Sensor PIR ini akan mengirimkan sinyal ke unit sistem kendali. Pengendali akan mengirimkan data hasil pengolahan ke motor sehingga dapat membuka tutup pintu secara otomatis.

<span lang="EN-US">In this paper, circular-shaped microstrip antenna was simulated, fabricated, and measured accordingly. As the novelty, to enhance bandwidth and reduce antenna size, beleved half-cut microstrip structure is proposed. Further, this proposed antenna structure will be applied to multiple input multiple output (MIMO) antenna 2</span><span lang="EN-US">´</span><span lang="EN-US">2. Therefore, this research was investigated conventional circular shape antenna (CCSA), circular shaped beleved antenna (CSBA), and MIMO circular shaped beleved antenna (MIMO-CBSA) as Model 1, Model 2, and Model 3, respectively. An FR4 substrate with er= 4.4, thickness h=1.6 mm, and tan d=0.0265 was used. The simulation has been conducted using Advanced Design System (ADS). The antenna CCSA/CSBA/ MIMO-CBSA achieve 1.831GHz/2.265 GHz/2.256 GHz, -15.13dB/-17.37dB/-17.25 dB, 1.42/1.31/1.33, and 1.474/2.332/2.322 for center frequency, reflection coefficient, VSWR, and bandwidth, respectively. This antenna has a size 63x90 mm and 51.5x90 mm for CCSA (Model 1) and CSBA (Model 2), respectively. After the structure of MIMO 2</span><span lang="EN-US">´</span><span lang="EN-US">2 was applied, the size of antenna MIMO-CBSA (Model 3) became 180 mm x 180 mm with a mutual coupling (S₂₁)=-26.18 dB and mutual coupling (S₃₁)=-26.41 dB. The result showed that proposed antenna CSBA (Model 2) has wider-bandwidth of 58,2% and smaller-size of 18.2%. Furthermore, after CSBA (Model 2) structure was applied to MIMO 2</span><span lang="EN-US">´</span><span lang="EN-US">2 (Model 3) and the MIMO antenna obtain good mutual coupling (&lt;-15dB). Moreover, the measured results are good agreement with the simulated results. In conclusion, all of these advantages make it particularly valuable in multistandard antenna applications design such as GSM950, WCDMA1800, LTE2300, and WLAN2400.</span>
