<![CDATA[Flame is a phenomenon of rapid oxidation of an element in a physical and chemical reaction process that produces heat, light, and other chemical products. Flame testing aims to quantify the presence of a particular element through the emission spectrum of each element. In addition, the physical characteristics of the fire object were also observed. Image-J software is one of the practical supporting applications that is often used for observing flame objects specifically in the fields of chemistry, physics, and energy. Experimental results have shown the level of accuracy of object dimensions and spectrometry with an accuracy rate of 97%. Differences in measurement ranges are often triggered by the image of the object and the foresight of the researcher.]]>

<![CDATA[The contact between ball and tennis racket is a collision phenomenon. The ball exerts a force on the racket which causes deflection. This study aims to obtain the deflection characteristics of a tennis racket due to ball contact. The research was conducted by experiment with Kinetic brand rackets. The racket is clamps on the grip. The ball used is Nassau brand with 0.058 kg of mass. Free fall is arranged 1, 2 and 3 meters heights, with 3 hitting points on racket string. The deflection measurement uses the pen method at 5 points on racket frame. Five points are arranged sequentially from the grip with 6 cm distance. Data collection was carried out with 3 repetitions to get average value. The deflection was measured using a caliper with 0.01 mm accuracy. The results show that the deflection has a linear characteristic and depends on the momentum of the ball]]>

<![CDATA[Wood chipper machine is a tool used to crush wood waste into powder (particles). This study aims to determine the effect of the distance between the blades and the hopperangle due to wood chipper machine performance. The distance between the blades was varied by 2 mm and 3 mm. The hopper angle was varied by 45o, 50o, and 55o. Measurement of sengon woodparticlesis done by using wire-mesh with sizes of 1.19 mm, 0.25 mm, and 0.15 mm. The result of the study show that there is an effe ct of the distance between the blades and the hopperangle dueto wood chipper machine performance.]]>

<![CDATA[PT XXX merupakan suatu perusahaan yang bergerak di bidang manufaktur kertas dan karton. Converting Plant merupakan salah satu plant yang ada di perusahaan tersebut dimana terdapat suatu kompresor sentrifugal yang merupakan equipment sangat kritikal karena kompresor tersebut mengalirkan udara bertekanan ke semua mesin produksi. Kompresor hanya dilakukan perbaikan jika ada kerusakan pada komponen-komponennya tanpa dilakukan analisis lebih lanjut kinerja kompresor sebelum terjadinya penurunan kinerja serta analisis penggunaan energi motor listrik sebelum terjadinya penyimpangan penggunaan energi motor listrik. Nilai efisiensi isentropik terendah ada di angka 0.82 dan 0.83 dengan penggunaan energi listrik sebesar 384.30 kW dan 383.1 kW. Nilai beban operasi tertinggi ada di nilai 86.9% dengan penggunaan energi listrik sebesar 384.30 kW. Nilai beban operasi terendah ada di angka 85% dengan penggunaan energi listrik sebesar 371.67 kW. Nilai optimum penggunaan energi listrik ada pada efisiensi isentropik 0.98-0.99 dan beban operasi 85% - 85.3% yaitu 371.67 - 372.15 kW.]]>

<![CDATA[This research modifies the bottle jack to remove the electric motor bearing of a water pump with a jack capacity of 2 tons. Bottle jacks are generally used to lift vehicles such as cars. The bottle jack can be modified so that it can be used as a bearing removal device. In general, the way to remove the bearing is still manual, namely by hitting it. The purpose of making this tool is to make it easier to remove the water pump electric motor bearing. The specifications of the tool are that it has a height of 16 - 27 cm. The width of the tool is 6 cm and the maximum pressure capacity of the bottle jack is 2 tons. The trial results of the bottle jack modification tool to remove the water pump electric motor bearings obtained an average time of 45 seconds.]]>

<![CDATA[energy as a source of electrical energy, both solar, wind, hydro and other renewable energy sources, a potential source of uranium in Indonesia.What needs attention is how to design energy policies to use each type of energy optimally, so as to avoid over-exploitation of fossil energy on the one hand, and on the other hand prevent neglect of renewable energy sources. In an effort to overcome this, the central and regional governments have made new policies that encourage the use of renewable energy sources as an alternative to supplying electricity to rural communities.The aims and objectives of the Feasibility Study Preparation Activity for the Benuis Micro-hydro Power Plant (PLTMH) Benuis Village, Selimbau District are; Availability of technical documents that describe the detailed design of the PLTMH and the Budget Plan (RAB) for the Benuis PLTMH Benuis Village. As a proposal for the construction of network facilities and infrastructure electricity..]]>

<![CDATA[PT XXX merupakan suatu perusahaan yang bergerak di bidang manufaktur kertas dan karton. Converting Plant merupakan salah satu plant yang ada di perusahaan tersebut bergerak di bidang manufaktur carton box atau biasa kita kenal kardus kemasan. Pada plant tersebut terdapat suatu kompresor sentrifugal yang merupakan equipment sangat kritikal karena kompresor tersebut mengalirkan udara bertekanan ke semua mesin produksi yang ada di plant. Kebutuhan produksi yang tinggi pada plant tersebut, kompresor hanya dilakukan perbaikan jika ada kerusakan pada komponen-komponennya tanpa dilakukan analisis lebih lanjut kinerja kompresor sebelum terjadinya penurunan kinerja serta analisis penggunaan energi motor listrik dan penyimpangan penggunaan energi motor listrik. Tujuan utama dari penelitian ini yaitu menganalisis penurunan kinerja kompresor dan pemborosan energi motor listrik kompresor berdasarkan parameter-parameter yang ada di kompresor. Nilai efisiensi isentropik terendah ada di angka 0.82 dan 0.83 dengan penggunaan energi listrik sebesar 384.30 kW dan 383.1 kW.
