Abstract

Motor arus searah (motor dc), khususnya tipe penguatan terpisah, memiliki karakteristik pengaturan kecepatan yang sangat baik, karena flux-producing dan torque-producing components currents dalam keadaan independen satu sama lain. Hal ini terjadi karena konstruksi fisik motor dc dimana komponen arus yang menghasilkan torsi dan komponen arus yang menghasilkan fluk sudah terdekopel secara alami. Dengan demikian pengaturan kecepatan motor bisa dilakukan dengan teknik pengaturan yang tidak rumit dan tidak memerlukan perangkat keras mahal. Pengaturan kecepatan motor dc bisa dilakukan dengan pengaturan arus jangkar atau arus medan secara bebas dan/atau simultan. Pemilihan variabel kontrol ini tergantung dari daerah operasi dari drive.Untuk pengaturan kecepatan dari diam sampai dengan kecepatan nominal dilakukan dengan pengaturan arusjangkar dimana arus medan dijaga konstan. Sedangkan untuk pengaturan kecepatan di atas kecepatan nominal dilakukan dengan memperkecil arus medan (field weakening). Dalam paper ini akan dibahas modeling pengaturan motor dc penguatan terpisah yang disimulasikan dengan Matlab Simulink.

Abstract

One of the positive impacts arising from technological developments is the ease in conveying aspirations and in obtaining information very quickly. The benefits of this technological development can be felt by all sectors, including the government sector which must protect the people and the state. In improving the quality of public services, the government must implement a government based on digital information technology. Therefore, the central and regional governments have provided online-based public complaint services. To improve the quality of service, the online complaint system must run optimally. The methods that are widely used to find the similarity of the complaint text are the cosine similarity method and the Artificial Neural Network (ANN) method for classifying complaint data. This study reviews the application of the two methods to determine the level of accuracy before it can be implemented in the online complaint system. The results of the review state that the Cosine Similarity method has an accuracy rate of 71.5% and ANN has an accuracy rate of 77%. While other method have an accuracy rate of 67%. From the percentage of this values, its can be concluded use of Cosine Similarity and ANN methods is feasible to use in classifying data in the Online Community Complaint System.

Abstract

One method to process toxic waste of hospital is incinerator. An incinerator burns hospital toxic waste at high temperatures. Many hospitals have to transport their toxic waste to rhid party location which often far away. In Bali, there are 62 hospitals with 6.195 beds with 5.584.310 annual visits from patients from patients and therefore generate large amount of toxic waste. Hospitals in Bali have to send their waste to incinerators in other island a few thousand kilometres away. This practice is expensive and add more environmental problems due to emmisions from transport vehicle and traffic congestion on the Java to Bali land transports. One solution is to develop small sclae incinerator near hospital’s site. This paper discuses the development of small incinerator in Denpasar city of Bali covering insvestment, performance metric, and economical feasibilty. The project is funded by international aid and currently the only incinerator on the island. Description of the plant component, environmental metric, investment analysis Keywords — Hospital, waste treatment, toxic waste, incinerator, environmental, economical feasibility, NPV, payback period, energy conservation.

Abstract

Rumah Sakit Surya Husadha Denpasar merupakan rumah sakit berstandar internasional dengan tingkat hunian kamar pada tahun 2011 cukup tinggi sekitar 75%.Yang berdampak pada tingkat pemakaian energi listrik. Tingkat pemakaian energi listrikrumah sakit tiap bulan rata-rata sebesar 123,071 kWh, diperuntukan pengoperasian AC sebanyak 43%, peralatan medis 29%, lampu 13%, elektronik 11% dan lainnya 4%. Dalam hal ini konservasi energi yang dilakukan difokuskan pada AC dan lampu karena hal tersebut memungkinkan untuk dilakukan pengontrolan pemakaian, penggantian peralatan dan tidak termasuk kategori peralatan vital seperti halnya peralatan medis. Dari tahapan audit energi diperoleh data bahwa nilai IKE adalah 245,40 kWh/m2/tahun. Sebanyak 37,1% kapasitas AC dan 84,54% kuat pencahayaan telah sesuai dengan pembebanan ruangan dan pedoman pencahayaan rumah sakit. Untuk perancangan manajemen energi, pimpinan rumah sakit belum memiliki acuan penyusunan sehingga perlu dilakukan pemetaan terhadap kebijakan dan sistem, organisasi, motivasi, sistem informasi, promosi dan investasi. Rancangan manajemen energi yang disusun mengacu pada matriks manajemen energi. Hasil matriks manajemen energi menunjukan bahwa manajemen energi rumah sakit belum terkelola dengan baik namun dalam hal penerapan teknologi dan sistem perawatan lampu dan AC dapat dijadikan best practice.

Abstract

The high fuel demand in Indonesia has resulted in an increase in the ratio of imported fuels and weakened domestic energy security. In response to this, biofuels (BBN) was developed, one of which was bioethanol. The raw material for making bioethanol can be from a variety of objects, but paper is the most easily obtained bioethanol raw material around us. PT Temprina Media Grafika a subsidiary of Jawa Pos Group produces waste paper every day. From the waste is processed into bioethanol and is used as a generator fuel. From 1 kg of paper waste obtained 30 ml of bioethanol with a concentration of 86%. By mixing bioethanol in gasoline, a mixture of fuels called E85, E60 and E35 is obtained. While pure RON 88 gasoline from Pertamina is called E10. Through testing on the generator set with a load of 600 watts and 900 watts, measurements of voltage, power, frequency, RPM and SOFC were obtained that all parameters decreased when using bioethanol mixed fuels.

Abstract

An on-grid solar power plant will distribute electric power to the grid in normal conditions. But when the supply of grid outages (islanding), on-grid solar power plant also can’t operate because the loss of the reference signal that is used as a reference for the inverter in the synchronization process. So there is potential loss of power when solar power plant can be used as a substitute source of electrical energy while PLN can’t serve consumers. In this research developed a simulation model that refers to the off grid solar power plant 500 Wp in the Department of Electrical Engineering, University of Udayana and can operate on-grid and off grid when islanding in matlab simulink. In this model made operation scenario where solar power plant operates on grid at the beginning of the simulation and after that operate off-grid (not connected to the grid and supply the local load). The simulation results show the model off grid solar power plant has been able to generate a voltage of 220 V and a frequency of 50 Hz in accordance with the solar power plant at the research site. The simulation results also show model of on grid solar power plant has been able to synchronize to the low voltage grid of PLN not loaded and loaded. On/off grid solar power plant model can operate on-grid or off-grid that corresponds to the operation scenario and produce the same output. Thus solar power plant can supply.

Abstract

Kebijakan feed-in tariff (FiT ) telah diterapkan di banyak negara dalam rangka meningkatkan pemanfaatan sumber energi baru dan terbarukan sebagai sumber energi alternatif. Melalui Permen KESDM No. 17 tahun 2013, pemerintah Republik Indonesia telah menetapkan kebijakan FiT untuk PLTS yang mempergunakan system photovoltaic. Dikeluarkannya kebijakan ini,  dengan harapan dapat menarik minat para investor untuk membangun PLTS dalam rangka mencapai target bauran energi nasional yang optimal pada tahun 2025 dimana peran energi baru dan terbarukan sebesar 23%. Metode yang dipergunakan dalam menghitung tarif penjualan listrik adalah metode Life Cycle Cost (LCC), merupakan metode yang menghitung keseluruhan biaya sebuah sistem mulai dari perencanaan, pembangunan, operasional & maintenance, penggantian peralataan, dan salvage value selama umur hidup sistem tersebut. Tarif penjualan listrik dalam paper ini dihitung dengan menambahkan margin keuntungan pada hasil perhitungan Levelized Cost of Energy (LCoE), dan nilai LCoE adalah total present value LCC dibagi dengan total present value energi yang dibangkitkan. Hasil perhitungan mendapatkan tarif penjualan listrik sebesar Rp. 1.981/kWh yang memenuhi harga patokan tertinggi FiT. Untuk menganalisa secara ekonomi kelayakan nilai penjualaan listrik ini, dipergunakan 4 metode yaitu  metode Pay Back Period (PBP), Net Present Value (NPV), Inernal Rate of Return (IRR) dan Profitability Indek (PI).
