Abstract

Based on data from Bank Indonesia, there are 1.67 million Indonesian migrant workers in Malaysia, both in the formal and non-formal sectors. One of the destinations for Indonesian migrants is Pulau Pinang, Malaysia. PERMAI stands for Pertubuhan Masyarakat Indonesia di Pulau Pinang Malaysia, which is a non-governmental, non-political NGO engaged in social education and culture. Efforts to apply occupational safety and health (K3) to workers are very important for workers when carrying out work activities. Especially for employees who work in a work environment that has high safety and health risks, work safety in the company is not only caused by the system that has been implemented by the company but also by the awareness of everyone to avoid work accidents. The purpose of this activity is to provide an introduction to occupational health and safety (K3) to business owners and workers who are in Pulau Pinang, Malaysia, and to equip business owners and workers to apply K3 in their work activities to prevent injuries, occupational diseases, or accidents. The method used in this activity is to provide health promotion counseling on occupational health and safety. This counseling uses media in the form of leaflets and provides pre- and post-tests in the form of questions and questionnaires to workers to determine their knowledge and understanding. The evaluation results show that the level of compliance with wearing personal protective equipment ("APD") is still low, with a percentage of 37%. Based on the IPA Cartesians diagram, variables X5, X6, and X8 are variables that have importance and good performance.

Abstract

Cooling Tower buildings are examples of construction that is directly exposed to adverse weather conditions that cause concrete damage in the form of carbonation. damage such as concrete cover spalling, cracks on the surface of concrete walls, and corrosion of reinforcement, Conditions like this need to be handled seriously because they have an impact on the structural safety factor of the building. This study aims to determine the effect of carbonation on the concrete structure of the Geothermal Power Plant Cooling Tower Building on Mount Salak which has experienced degradation of concrete quality due to carbonation. Concrete Analysis method to determine the relationship of the effect of carbonation on concrete strength in the Cooling Tower structure uses Monte Carlo simulation method based on measurements of concrete cover and carbonation depth. Monte Carlo simulation results to estimate the carbonation rate of concrete showed an average of 2.4 cm per year for a simulation period of 25 years. The average carbonation of concrete obtained from probability is 2.28. By repeating the simulation, an average value close to the estimate will be obtained from the coefficient of determination test results of 48.1%. The effect exerted by concrete quality on concrete carbonation is negative, meaning that better concrete quality will reduce concrete carbonation.

Diperoleh bahwa keefektifan algoritme wavelet-FxLMS sebagai strategi kontrol getaran aktif nonlinear telah berhasil didemonstrasikan baik secara eksperimental maupun teoritis di bawah osilator bangun Van der Pol.Kata kunci: kontrol adaptif, teori kontrol, sistem kontrol, kontrol getaran, sistem kontrol non-linier. ABSTRACTIn this paper, we present a novel feedforward control strategy presented for the control of flow-induced vibration of a tube cylinder supported by a transversely mounted elastic cantilever beam. The control strategy aims to limit the movement of the tube cylinder which is supported by elastic cantilever beams, to prevent optimal vibration which will result in a nonlinear system. The feedforward control system uses a combination of multiresolution wavelets and the Filtered-x least mean square (FxLMS) control algorithm. To verify the control feasibility of the proposed algorithm, a numerical effort using Van der Pol equation and the results of implementing it in the experiment was carried out to reveal the response vibrations that occur over time. It was found that the effectiveness of the wavelet-FxLMS algorithm as a nonlinear active vibration control strategy has been successfully demonstrated both experimentally and theoretically under a Van der Pol wake oscillator.Keywords: adaptive control, control theory, control systems, vibration control, nonlinear control systems.

                             Agung Wahyudi Biantoro                       Mechanical Engineering Department,  Universitas Mercu Buana, Jakarta.                               Jl. Meruya Selatan No. 1, Jakarta Barat.  Email : agung_wahyudi@mercubuana.ac.idPresent the need for efficient transportation is very important for modern human life. Various types of studies continue to be carried out to support the implementation of the use of Gas Fuel (CNG), to reduce dependence on fossil fuels. The use of BBG is considered more efficient and environmentally friendly than using fuel oil (BBM). However, thus, the use of CNG can hurt a negative impact on human safety and even cause considerable losses if it is not used carefully, especially if there is no known leakage from the tube and cause a fire to the vehicle. CNG gas that has a leak does smell so normal leakage is easily detected. However, if the leaky gas seeps into the engine, and the bottom of the bus or under the carpet, it will be difficult to detect. CNG gas is famous for its flammability so that the leakage of CNG equipment is at high risk of fire. Based on this description, the need for an early gas leak detection device using a microcontroller can monitor the presence of gas leaks in vehicles that can be observed directly through the LED screen in the form of a warning that can be placed on the cabin dashboard. From the above problems, the authors are interested in making a study by creating an innovation tool called GLEDS (Gas Leakage Early Detection System) in Microcontroller-Based Motorized Vehicles. The purpose of this study was to determine the condition of the design of the gas cylinder position in motorized vehicles and design the manufacture and GLEDS tool to detect gas leaks in motorized vehicles. Based on the whole system starting from the design and manufacture of GLEDS tools The conclusion is that the GLEDS gas leak detector can work well, this is indicated by the functioning of the tool when given butane gas. The buzzer sounds, the green LED lights up and displays graphical data on Android. Next, the sensor will detect a leak in the gas cylinder, if near the gas cylinder regulator there is really a butane gas content at a concentration of 280 ppm which then increases to 400 ppm. At a concentration of 300 ppm, the tool works well, with active buzzer alarms and LED lights. This GLEDS tool can be placed in the trunk of a car, close to gas cylinders of LNG four-wheeled motorized vehicles. Keywords: Gas Leak Detection, GLEDS, Arduino Uno, Microcontroller

Abstract

Abstrak. Sampai saat ini, 95% dari kebutuhan energi nasional masih dipenuhi energi fosil, sementara kontribusi energi terbarukan baru mencapai 5%. Indonesia masih tergolong boros dalam menggunakan energi yang ditunjukan dari nilai intensitas energi yang masih tinggi. Salah satu cara pengurangan energi gedung adalah dengan efisiensi dan audit energi di Gedung tersebut. Penelitian ini dilakukan di Gedung Rumah Sakit BA, Tangerang. Tujuan dari penelitian ini adalah untuk menentukan IKE (Intensitas Konsumsi Energi), analisis potensi hemat energy, dan serta pengembangan software untuk perhitungan dan evaluasi penggunaan energy di Gedung Rumah Sakit BA. Metode yang digunakan adalah metode analisis deskriptif kuantitatif dengan memeriksa nilai IKE dan membandingkan secara umum kondisi konsumsi energy gedung tersebut dengan nilai standar pemerintah. Alat yang digunakan dalam penelitian adalah Environment meter, multimeter dan Tang ampere. Pengolahan data ini dilakukan dengan membuat aplikasi perangkat lunak, menggunakan program Visual Studio yang terkoneksi dengan Microsoft access sebagai penyimpan data. Dari hasil penelitian, didapatkan nilai Intensitas konsumsi energi (IKE) pada Gedung Rumah Sakit BA sebesar 23.73 kWh/m2/Bulan atau 284.076 kWh/m2/Tahun. Dengan menggunakan rujukan ASEAN USAID 1992, nilai ini masuk dalam kategori efisien, karena untuk IKE standarisasi gedung rumah sakit yaitu 380 kWh/m2/Tahun. Kondisi lampu penerangan masih menggunakan lampu TL dengan daya 36 watt dengan menggunakan armature jenis lama, sehingga pencahayaan kurang efisien. Kondisi AC split secara umum kinerjanya bisa dikatakan kurang efisien karena masih menggunakan freon jenis R22 yang tidak ramah lingkungan, boros dan masih banyak ruangan terbuka, sehingga menimbulkan potensi kerugian energy karena terbuang percuma. Dengan menganalisis potensi hemat energy, dan berbiaya rendah, maka, pengeluaran dapat dihemat hingga 30% dari total penggunaan energy selama satu tahun. Sedangkan dengan menggunakan aplikasi program hemat energy, maka tampilan dengan tampilan menarik dan handal, dapat memudahkan pemakai untuk mencari nilai IKE, mencari nilai Kwh dan biaya energy yang dipakai di gedung tersebut. Hasil perhitungan tersebut dapat disimpan, dicari dan dipanggil kembali saat sewaktu waktu diperlukan.

Abstract

A Microhydro Power Plant (MHP) with hydrocoil turbine in Sukajaya Lembang Village, Bandung, West Java, has been successfully designed. However, the velocity of the water flow after exiting the hydrocoil turbine is still relatively high, so there is still a lot of wasted flow energy before it can be converted. Like other reaction turbines, the hydrocoil turbine requires a draft tube in order to maximize its energy conversion process. Thus, the purpose of this research is to determine the type of draft tube based on the head recovery value and performance of the hydrocoil turbine for the MHP system. This determination process involves 3 stages: 1) evaluation of the performance of the hydrocoil turbine that has been installed with three types of draft tubes, namely conical straight, curved elbow, and simple elbow, by Computational Fluid Dynamics (CFD), 2) calculation of the head recovery of the three types of draft tubes, and 3) determination of the best draft tube based on the head recovery value and performance of the hydrocoil turbine. In stage one, the type of analysis used is steady state with the SST k-ω turbulence model, to capture turbulence in the penstock pipe and near the turbine blades. As the results, the highest hydrocoil turbine efficiency with all three types of draft tubes installed, is at a rotational speed of N=1100 rpm. The highest efficiency for the hydrocoil turbine with conical straight, curved elbow, and simple elbow draft tubes are 90.48%, 90.18%, and 91.26%, respectively. Meanwhile, the head recovery at rotational speed N=1100 rpm for conical straight, curved elbow, and simple elbow draft tubes are 1.627 m, 1.866 m, and 4.097 m, respectively. Thus, the simple elbow draft tube is the best to use in this MHP system because it has the highest head recovery and efficiency values.
