Today human need for electrical energy is very high. For that we need to find an alternative power plant renewable energy, especially environmentally friendly. One type of an environmenttally friendly power plant is a generator which is harnessing human-generated energy when exercising by using a static bike. This equipment is used on average 6 hours per day at 5.00-8.00 hours and 17:00 to 20:00 hours. In this research, a power plant system by utilizing human motion exercising from wheel rotary mechanics, generators, BCU (Battery Control Unit), and battery will be designed. The rider can see from the LCD when the battery condition is full, the battery is charge, the battery does not get energy from the generator, inverter on, inverter off, battery voltage and generator voltage. At the testing stage, 14 participants cycling for 15 minutes produced electrical energy on average of 594 Joules, with an age range of 20-23 years old. The resulting energy can turn on the light 3 Watt between 160 -251 seconds or 198 seconds on average. When accumulated 14 cycled samples with 15 minutes each (total 210 minutes) can generate 8313 Joule electric energy and can turn on 3 Watt lamp for 46 minutes 11 seconds.
Penyebaran virus Covid-19 di seluruh dunia belum bisa dihentikan. Perkiraan para ahli, wabah pandemik ini akan berlangsung lama, di Indonesia juga terjadi peningkatan kasus dan kematian secara signifikan. Saat ini virus sudah berada di sekitar kita, tidak menutup kemungkinan akan menjangkiti kita semua. Usaha yang dapat dilakukan adalah dengan meningkatkan kesehatan masyarkat dan di antaranya adalah peningkatan sistem imun, penggunaan antiseptik, dan disinfektan. Program pengabdian masyarakat ini telah dilakukan penyuluhan kepada masyarakat RT 06/01 Desa Padasuka, Kecamatan Cimenyan, Kabupaten Bandung bagaimana memanfaat energi elektrokimia, serta cara menggunakan alat Portable Mineral Water Ionizer agar dapat dimanfaat untuk meningkatkan kesehatan, sehingga sistem imun nya meningkat untuk menghadapi kemungkinan terjankitinya oleh virus Covid-19. Portable Mineral Water Ionizer menghasilkan air alkali yang mengandung gas hidrogen, bermanfaat untuk menghasilkan antioksidan sehingga meningkatkan sistem imum. Air asam yang dihasilkan dapat dimanfaatkan sebagai antiseptif dan desinfektan. Portable water ionizer ini dirakit dari bahan-bahan sederhana yang dapat ditemui di lingkungan masyarakat sekitar, seperti teko air sebagai wadahnya dan grafit pensil sebagai katoda dan anodanya. Masyarakat sasar dan mahasiswa ikut merakit water ionizer ini setelah penyuluhan berlangsung. Water ionizer yang telah dirakit kemudian di uji dan dibagikan ke masyarakat sekitar untuk digunakan konsumsi pribadi.
ABSTRAKTroli rotari memerlukan sistem kontrol untuk mengatur rak ke posisi yang diinginkan. Penelitian ini berfokus pada sistem kontrol posisi rak menggunakan metode Fuzzy Logic Controller (FLC) dengan beban berbeda dari setiap pengguna. Masukan pada sistem kontrol FLC adalah error dan delta error dari sensor rotary encoder. Keluaran dari FLC adalah Pulse Width Modulation yang digunakan untuk mengontrol kecepatan motor DC. Hasil penelitian dari tiga variasi fungsi keanggotaan keluaran dengan beban pada satu rak, pengujian tanpa beban memiliki settling time antara 3,11 s hingga 3,24 s dan error steady state antara 3 hingga 8 counter. Pengujian dengan beban 250 g memiliki settling time antara 3,92 s hingga 8,80 s dan error steady state antara –5 counter hingga 4 counter. Sedangkan pengujian dengan beban 500 g memiliki settling time antara 4,66 s hingga 7,39 s dan error steady state antara 8 counter hingga 12 counter.Kata kunci: tempat penitipan barang, troli rotari, Fuzzy Logic Controller. ABSTRACTRotary trolley needs control system that used for rack control to the position. The research focused on rack position control system using the Fuzzy Logic Controller (FLC) method with different loads from each user. Inputs to the FLC control system are error and delta error from the rotary encoder sensor. The output of the FLC is Pulse Width Modulation which is used to control the speed of the DC motor. The results from 3 variations of the meeting results, the no-load test had a completion time of between 3.11 s to 3.24 s and steady-state conditions between 3 counters to 8 counters. Testing with a load of 250 g has a completion time of 3.92 s to 8.80 s and steady-state conditions between -5 counters to 4 counters. While testing with a load of 500 g has a settling time of 4.66 s to 7.39 s and steady-state conditions between 8 to 12 counters.Keywords: deposit box, rotary trolley, Fuzzy Logic Controller.
The community service program from Telkom University aims to improve the ability and insight of learning technology using Camtasia Studio at SMPN 1 Baleendah. The method used in community service is a form of training or workshops where the participants, in this case are teachers, are given training for a maximum of 3 hours, instructors in this case are from Telkom University. The stages carried out in this training are broadly as follows: The stages of making or recording material content, the editing or editing stages of material content and the stages of uploading learning material content. Participation by partners is in the form of providing space, infrastructure such as laptops or computers (computer laboratory recommendations), internet networks, and teachers’ resources to be given Camtasia Studio training. Based on the results of the initial survey it was found that 15% had experience in making interactive videos by using programs other than Camtasia studio, and as many as 85% of the teachers are inexperienced in making interactive videos because they only use learning media based on whatsapps, zoom and google classroom. After the training, there was an increase in the skill level of making interactive videos for all participants. As many as 75% of the teachers strongly agree regarding the suitability of the programs held with the aim of carrying out activities. Lecturers and students are stated to be more friendly, faster and responsive in helping during the practical activities of creating interactive video content using Camtasia studio.
