Abstract

ABSTRACT Waste is a problem that we often encounter in society. The increase in population causes an increase in the amount of waste produced. Waste management methods that are not environmentally friendly can cause negative impacts on health and environmental damage. Unfortunately, the understanding of a clean and healthy lifestyle in society, especially among the younger generation, is still lacking. The younger generation has not been able to understand the use of simple technology that can be used to overcome this waste problem, including the concept of gasification. This community service will explain one way to deal with waste by making synthetic gas. The implementation of this community service event is divided into three sessions. The first session was a plenary presentation about the general knowledge of waste management that already exists in several big cities both domestically and abroad, up to a technical understanding of how to do it to solve the problem of waste handling in the surrounding environment. Session two is a trial session or demonstration of synthetic gas-producing equipment using a biomass reactor so that high school students can have psychomotor knowledge and abilities to operate a biomass reactor. The third session was in the form of exposure to critical input and suggestions as well as feedback so that there was a closer and communicative interaction between community service providers and the community service’s target. The results showed the high enthusiasm of the community service participants to overcome the problem of organic waste by converting it into electricity through the gasification process. Keynote: Student’sAawareness, Gasification, Waste Management.       ABSTRAK Sampah adalah masalah yang sering kita jumpai di masyarakat. Pertambahan jumlah penduduk menimbulkan peningkatan jumlah sampah yang dihasilkan. Metode pengelolaan sampah yang tidak ramah lingkungan dapat menyebabkan dampak negatif bagi kesehatan dan kerusakan lingkungan. Sayangnya, pemahaman tentang pola hidup bersih dan sehat di masyarakat, khususnya di kalangan generasi muda, masih kurang. Generasi muda belum bisa memahami pemanfaatan teknologi sederhana yang dapat digunakan untuk mengatasi permasalahan sampah ini, termasuk diantaranya adalah konsep gasifikasi. Pengabdian kepada masyarakat ini akan menjelaskan salah satu cara mengatasi sampah dengan pembuatan gas sintetis. Pelaksanaan acara pengabdian kepada masyarakat ini dibagi menjadi tiga sesi. Sesi pertama merupakan pemaparan pleno tentang pengetahuan secara umum pengolahan sampah yang sudah ada di beberapa kota-kota besar baik di dalam negeri maupun di luar negeri, sampai dengan pemahaman teknis bagaimana melakukannya untuk menyelesaikan permasalahan penanganan sampah di lingkungan sekitar. Sesi dua merupakan sesi uji coba atau demonstrasi peralatan penghasil gas sintetis dengan menggunakan reaktor biomassa sehingga siswa SMA dapat memiliki pengetahuan dan kemampuan secara psikomotorik untuk melakukan pengoperasian reaktor biomassa. Sesi ketiga berupa pemaparan masukan kiritik dan saran serta umpan balik sehingga ada interaksi yang lebih dekat dan komunikatif antara penyelenggara pengmas dengan pihak sasaran atau target pengmas. Hasil menunjukkan antusiasme yang tinggi dari para peserta pengmas untuk mengatasi permasalahan sampah organik dengan mengubahnya menjadi tenaga listrik melalui proses gasifikasi. Kata kunci: Kesadaran Siswa, Gasifikasi, Pengelolaan Sampah.

Abstract

Rooftop photovoltaic (PV) plant is one ot the independent electricity that us favorable in recent year. Rooftop PV plant can be used as the source of smart building as well as fast charging station. Although rooftop PV plant could provide clean and sustainable energy from solar, they also come with disadvantages in term of intermittent power output. This intermittent power output is due to the uncertainty of the source. To tackle this problem, maximum power point tracking method is essential. Maximum power point tracking (MPPT) method can be used to extract maximum power from the solar cell in all conditions. This paper proposes an intelligent method for designing DC-DC MPPT based on fruit fly optimization (FFO) on realistic rooftop PV plant. Practical rooftop PV plant in Universitas Airlangga is employed as the testing system. The proposed method's efficacy is evaluated using time domain simulation. According to the simulation results, the proposed method can significantly extract power from PV.

Abstract

Along with its development, optical fiber has been modified into sensors because of its various advantages. In the fabrication of a modified fiber optic sensor in the form of a taper innovation, the sensor geometry becomes the main parameter that can affect the sensitivity of the sensor. The fiber taper works by allowing the evanescent waves out of the waveguide to interact with the stimulus, thus providing a sensor mechanism. The fabrication of the fiber taper in this study was carried out using the drawing and heating method continuously and simultaneously. Based on this fabrication process, the optical fiber is pulled using an autograph until it enters the plastic deformation region. Mechanical properties analysis showed that the optical fiber has a stress of 54.21 MPa and an elastic modulus of 2.46 GPa. It was also found that the optical fiber experienced an elongation of up to 11.02%. The results of the digital microscope test showed that the taper process succeeded in reducing the diameter of the optical fiber by 18.40%. Besides the ease of processing, the advantage of fabrication using this method is that the mechanical properties are measured in real-time, making this method reproducible on a mass scale.

Abstract

The most common problem in spark ignition engine is how to increase the speed performance. Commonly researchers used traditional mathematical approaches for designing speed controller of spark ignition engine. However, this solution may not be sufficient. Hence, it is important to design the speed controller using smart methods. This paper proposes a method for designing speed controller of a spark ignition engine using the bat algorithm (BA). The simulation is carried out using the MATLAB/SIMULINK environment. Time domain simulation is carried out to investigate the efficacy of the proposed method. From the simulation results, it is found that by designing speed controller of spark ignition engine using PI based bat algorithm, the speed performance of spark ignition engine can be enhanced both in no load condition and load condition compared to conventional PI controler.

Abstract

A low cost, highly sensitive sensor with easy fabrication has been successfully developed to detect variations in the concentration of sucrose solutions using a microfiber probe sensor. The microfiber probe was fabricated using a flame brushing mixture of butane and oxygen with single-mode optical fiber material and pulled on both sides to achieve a size of 16.48 µm. These microfiber probes were characterized into two sensor probe shapes: straight and u-shaped, to measure variations in the sucrose solution concentration. The results for both probe shapes showed a decrease in peak output intensity and a shift in peak wavelength as the sucrose concentration increased from 0.5% to 3%. The straight shape exhibited a sensitivity of 0.241 dBm/% with a slope linearity of 99.5% and a resolution of 0.0415%, while the U-shape had a sensitivity of 2.692 dBm/% with a slope linearity of 90.6% and a resolution of 0.0030%. The measurement spectra results indicated significant differences in u-shape at each concentration. In conclusion, both microfiber sensor probe shapes exhibited excellent performance and are suitable for use as chemical sensors to measure variations in solutions.
