Hidroponik adalah teknik bercocok tanam dengan menggunakan media selain tanah, contohnya adalah air. Air merupakan nutrisi bagi tanaman yang disirkulasikan dengan pompa. Sirkulasi air beroperasi secara terus-menerus, untuk itu memerlukan daya listrik dalam jumlah besar, sehingga membutuhkan panel surya sebagai alat yang dapat mengkonversi cahaya matahari menjadi energi listrik. Panel surya digunakan untuk menyalakan pompa dan sistem kendali pH dan level larutan nutrisi. Panel surya diuji dengan variasi kemiringan sudut, sedangkan sistem kendali pH dan level larutan nutrisi diuji menggunakan respon waktu. Set point kendali pH yaitu 6-7 dan kendali level larutan nutrisi yaitu 18-20 cm. Berdasarkan pengujian yang dilakukan, panel surya menghasilkan daya listrik terbesar 20,59 watt pada sudut 0° Pukul 12:15, sedangkan daya terkecil 2,54 watt pada sudut 30°pukul 15:00. Adapun rata-rata waktu yang dibutuhkan untuk mengendalikan pH <6 yaitu 12 menit , sedangkan kondisi >7 yaitu 18 menit, dan waktu yang dibutuhkan untuk mengendalikan level larutan < 20 cm yaitu 1 menit. Rata-rata perhari daya listrik yang dihasilkan panel surya adalah 244,4 watt dan daya yang digunakan untuk mengoperasikan pompa hidroponik beserta sistem kendalinya yaitu 123,9 watt. Dengan demikian, panel surya yang digunakan dapat mengoperasikan sistem pengendalian pH dan level air nutrisi tanaman hidroponik sampai masa panen.

Industrial application of so-called "green energy", which uses the piezo elements of a small scale in renewable energy sources, is given in Reference [2]. The actual idea of Industry 4.0, i.e., Internet of Things (IoT), accounting for an energy harvesting system, where the intelligent electric energy management methods are employed.…”

The paper presents the design, fabrication, and characterization of an energy harvester for an active magnetic bearing (AMB) rotor vibration using a macro fiber composite (MFC) with magnetic coupling. The MFC cantilevers configuration, together with neodymium magnets, is used for the contact-free rotor radial vibration self-powered sensor. The permanent magnets attached to the rotor and to the four MFC element beams ensure the mechanical energy transfer and the MFC cantilever vibration excitation. In the proposed prototype, the MFC transducer output voltage depends on the air-gap between two magnets. This paper investigates the optimum conditions to harvest as much as possible electric energy at different clearances and rotational speeds. Furthermore, to assess the rotor vibration sensitivity, the experimental results of the MFC-magnet self-powered sensor are compared with measurements obtained using a fiber optic sensor. The maximal obtained harvesting power equals 673.47 µW for the rotor speed of 3150 rpm. Moreover, the MFC cantilever was proposed as the rotor vibration sensor. The MFC-magnet self-powered vibration sensor output was compared with the fiber optic laser sensor. The mismatched vibration amplitude for both sensors does not exceed 1 µm.

Energy harvesting is a promising alternative to batteries for autonomous WSN nodes. Although there are various energy harvesting methods using ambient energy sources, this research is focused on thermal energy harvesting because there are abundant thermal sources in industrial sites. As only several mW can be obtained by a thermal energy harvester based on a thermoelectric generator (TEG), improvement of the energy conversion efficiency of the thermal energy harvester is essential. This paper proposes a novel maximum power point tracking (MPPT) method combining coarse adjustment and fine adjustment to enhance the energy conversion efficiency of the harvester. The Direct Adjustment (DA) method for MPPT is adopted in the coarse adjustment stage to avoid disconnecting TEG modules from conversion circuits, while an observation and self-optimization (O&SO) method for MPPT is used in the fine adjustment stage to avoid introducing perturbations and to maintain a stable output power at the maximum power point (MPP). After building up the system simulation model, a series of experiments are conducted to evaluate the proposed MPPT methods. The results show that the DA+O&SO method is an effective MPPT method for a WSN node powered by a TEG. It is able to enhance the regulation speed of the MPPT, improve the continuity of P out , and avoid the power oscillations around the MPP.
