Piezoelektrik adalah material yang menghasilkan energi listrik berdasarkan pengaruh tekanan yang diberikan. Pada penelitian ini piezoelektrik diaplikasikan dengan memanfaatkan tekanan air hujan, hal ini bertujuan untuk mengurangi penggunaan listrik dari pemerintah untuk skala kecil di rumah tangga. Bahan dasar yang digunakan dalam membuat piezoelektrik adalah baking soda, distilled water dan cream of tartar. Penelitian ini dilakukan dengan menentukan ukuran cetakan piezoelektrik yang terbaik menggunakan CAD Code, yaitu 1 x 1 x 0.5 cm3. Selanjutnya dilakukan pembuatan material piezoelektrik dengan mereaksikan beberapa bahan, lalu hasilnya diuji dengan multimeter digital dan osciloscop. Hasil tegangan pada osciloscop berurutan dari tekanan rendah, normal dan tinggi adalah 0.104 DC Volt, 0.496 DC Volt, dan 0.720 DC Volt. Setelah didapatkan hasil tegangan selanjutnya, dilakukan pembuatan rangkaian listrik seri dan menghasilkan tegangan sebesar 2.0 DC Volt, 2.10 DC Volt dan 2.34 DC Volt. Kemudian dibuat rangkaian listrik dan pengujian model piezoelektrik agar dapat diketahui kinerja piezoelektrik pada sistem.Kata kunci : energi, curah hujan, desain, piezoelektrik, pengujian

Harmonik arus maupun harmonik tegangan adalah salah satu permasalahan yang umum terjadi dalam suatu sistem tenaga yang memiliki komponen berupa beban non-linier. Harmonik arus maupun harmonik tegangan dapat mempengaruhi kestabilan dari sistem tenaga dan memberikan dampak yang buruk untuk komponen kelistrikan yang lainnya, Oleh karena itu diperlukan suatu langkah yang perlu dilakukan untuk meminimalisir dampak buruk dari kasus tersebut salah satunya adalah dengan menggunakan filter pasif. Tujuan penelitian ini akan melakukan desain model High-Pass Damped Filter dengan menggunakan data yang didapatkan dari hasil pengukuran dan simulasi menggunakan ETAP Program, sehingga dapat diketahui seberapa besar pengaruh high-pass damped filter dalam mereduksi harmonik arus dan tegangan yang terdapat dalam sistem untuk menganalisis perancangan filter untuk beban FL-2 pada PL-LB/1.

The use of nanoparticle coolant fluid in the car radiator increases the rate of heat transfer and facilitates the reduction of the overall radiator size. In this study, heat transfer characteristics of tri-hybrid nanofluids-based water/EG (60:40) were analyzed experimental and compared with water/EG (60:40). Four different nanofluids concentrations were prepared by adding 0.05 to 0.3 vol.% of tri-hybrid nanofluids dispersed a mixture of water/ethylene glycol (60:40). Experiments were carried out by varying the flow rate of coolant between 2 to 12 LPM for working temperature of 70 °C, the velocity of airflow remained at an average of 4 m/s, to understand the effect of coolant flow rate on heat transfer. The results showed that the thermal performance of tri-hybrid nanofluids in a water/EG (60:40) mixture has been investigated for volume concentrations of up to 0.3% and working temperature of 70 °C. The maximum enhancement of heat transfer coefficient for air side is observed up to 23.8% at 0.05% volume concentration meanwhile for coolant side is observed at 39.7% at 0.3% volume concentration. The pressure drop and pumping power have the same pattern which increasing in volume concentrations.

Some of the damage that occurs in the structure and construction of engine elements that experience dynamic loading at the time of operation is caused by fatigue (fatigue), which occurs without beginning signs so that it causes great damage and loss. Fatigue strength is the process of local changes in the structure that occur permanently in accordance with the period of time caused by conditions where stress or strain occurs which results in cracks or fractures after being subjected to repetitive loads. Surface roughness factors that affect fatigue are applied in the analysis and application of machining, which are finely grinded and rough machined. Analysis was carried out on 6063-TF aluminum alloy material which is widely used for motor vehicles. To find out the effect of the above, the fatigue strength test is carried out with a Rotary Bending Fatique Test to obtain a cycle value or fatigue age and certain neighbors so that it can make a semi-log S-N diagram with statistical calculations.

As time went on many problems were encountered in the unit, one of which was the problem experienced by the D155A-6 unit, which was overheating troubleshooting caused by abnormal fan motors. In handling the problem, it is difficult to determine the data of the motor fan. Therefore, an initiative is needed to create tools to help deal with problems that occur. The purpose of this study is the manufacture of adapter tools for measurement of hydraulic pressure fan motors in troubleshooting the overheat engine in D155A-6 units. The results of this study are analyzing the structure and function of the cooling system in troubleshooting the overheat engine in the D155A-6 unit.

The need for particleboard in Indonesia is increasing every year. Particleboard is usually made of wood that comes from the forest so it has a bad effect and forest products will decrease over time. To overcome this problem, new knowledge is created that can be done. The new knowledge is like utilizing empty palm oil bunches for particle board material to replace wood raw materials. Particleboard is usually made of wood or other lignocellulosic materials such as oil palm empty bunches. The empty fruit bunches that have been made will be mixed with polyester resin as an adhesive. This study examines the effect of the percentage of polyester resin adhesive used, namely 90%, 75% and 60%. The process of making particle board starts with the preparation of raw materials such as palm empty fruit bunches and polyester resin. For empty bunches fiber used is 1 cm long. After the particle board is made, a hardness test is carried out using a durometer with the ASTM D2240 standard.

The use of composite materials in Indonesia, as a nonmetal alternative material has begun to increase. Composite use has grown from water tanks from fiberglass materials, household appliances, children's toys, sports equipment, furniture/interior design to automotive components and aircraft. Many of the advantages of this composite material include hand, strong, anti-corrosion, finely tuned finish. Its mild nature has a direct impact on energy savings. The prospect of composite materials as a non-metal alternative material is rapidly growing and its use. Various types of reinforce used can be influenced by the prices available, so seek alternatives as a commonly used glass fiber substitute woven rowing. The substitute used is a sack of gourds of the same kind as woven rowing, from which the same type of fiber is tried to find its strength by undergoing a pull test. And as a result of the test the mateial can know its power.

The bulldozzer is seen as the most efficient heavy equipment unit for mining, specifically dozzing and ripping material. The purpose of this study was to analyze damage due to cracks in the cooler afterwards which caused dust and dirt to enter the air intake system which caused excessive piston, piston ring and cylinder wear liners in the Bulldozer. The research method was conducted using 8-step troubleshooting analysis. The results and discussion are damage due to cracks in the after cooler which causes dust and dirt into the air intake system which causes the piston, piston ring and cylinder liner to wear out excessively. The piston, piston ring and cylinder liner have excessive scratching and wear, so the compression pressure that should be compressed inside the combustion chamber experiences a leak where the air enters the crankcase chamber.
