Ketidaksejajaran (misalignment) poros menimbulkan getaran yang berlebihan sehingga dapat mengakibatkan kerusakan dini pada mesin dan selanjutnya memperpendek umur operasi mesin secara keseluruhan. Tujuan penelitian ini adalah untuk mengetahui besar getaran aligment poros, parallel misalignment dan angular misalignment yang berupa data simpangan, kecepatan dan percepatan. Penelitian ini dilakukan dengan mengukur getaran pada motor menggunakan vibration meter pada posisi aksial, vertikal dan horizontal. Pada posisi alignment poros, nilai displacement getaran terbesar terdapat pada arah pengukuran aksial dengan nilai 0.134x10-3 m, nilai velocity getaran yang tebesar terdapat pada arah aksial dengan nilai adalah 0.86x10-2 m/s, dan nilai acceleration getaran terbesar juga pada arah aksial dengan nilai 44.4 m/s2. Pada posisi paralel misalignment poros, nilai displacement getaran yang terbesar terdapat pada arah aksial (0.295x10-3 m), nilai velocity getaran vertikal terbesar juga pada arah aksial (1.38x10-2 m/s), dan nilai acceleration getaran yang terbesar juga pada aksial (60.3 m/s2). Pada posisi angular misalignment poros, nilai displacement getaran yang terbesar adalah pada arah aksial (0.301x10-3 m), nilai velocity getaran terbesar adalah pada arah horizontal dengan (1.55 m/s), sedangkan acceleration terbesar terdapat pada arah aksial (63.7 m/s2). Karakteristik dari getaran yang disebabkan oleh angular misalignment pada umumnya sama dengan parallel misalignment. Pada kondisi angular misalignment atau parallel misalignment, amplitudonnya lebih besar pada dua kali putaran poros dibandingkan satu kali putaran poros, dengan getaran terbesar terjadi pada arah aksial.

Handling of used aluminum has been carried out by collectors, namely the compression process. The pressing process is less economical because it still produces cavities and the selling price is low. The purpose of this community service activity is to provide training on Aluminum smelting with casting techniques for two groups of independent collectors, Mandiri Berkah and Maju Jaya. The activity took place in the Mandiri Berkah collector area which was attended by Mandiri Berkah and Maju Jaya employees and the community around Poasia. The method of implementing the activity is a theoretical explanation of Aluminum and its processing method with casting techniques. Used aluminum cans are melted in a charcoal-fired crucible furnace. The used aluminum cans are put in the kowi which is placed in a hot furnace. After the cans are melted, they are poured into rectangular molds. The results of the service activities that resulted were the opening of knowledge insights related to used aluminum. Participants were able to recycle Aluminum by casting technique into ingot products.Keywords: Training, foundry, aluminum, collectors

Dispensers have an important role in providing adequate drinking water for needs and can be placed around where we work. The purpose of this research is how to design and make an automatic dispenser system based on Arduino Uno and it can work well when filling the glass when the glass is placed. This research was conducted by coding using Arduino IDE 1.0.6 software to program Arduino Uno to control servo motors and ultrasonic sensors. The results of this study indicate that the automatic dispenser can work to fill glasses from a distance of 5 cm to 0 cm and open the dispenser faucet 1 cm. From the manufacture of this tool it can be concluded that this tool works well, in accordance with its purpose to make it easier to take water, the automatic dispenser is driven by a servo motor with a wire attached to the side of the dispenser lever, the control system uses Arduino Uno. Suggestions can be given so that this tool can be developed. Another suggestion for development is that so that the automatic system of this tool can work properly, the placement of the sensor must be in the right position so that the glass plate can be filled properly, it is better to turn on the Arduino uno by using a switch.

The development of building construction always requires materials, machines (equipment) and work methods to increase the efficiency of work completion. Sand material which is the main building material in the manufacture of a construction structure. The work method for separation is generally carried out by sieving which aims to obtain uniform sand sizes. In this study, a sand sieving machine was designed using the translation method of shaft rotary motion. Procedures in the design of the sand sieving machine are carried out by collecting initial data and field requirements regarding the sand sieving machine, determining the effective mechanism of the sand sieving machine, analyzing the elements of the sand sieving machine, and determining the design of the sand sieving machine. The working system of the machine is designed to use an electric drive motor, a pulley belt transmission system is used to reduce the rotation of the motor, then the eccentric drive shaft is used to rotate the crank which in turn moves the pusher rod so that the sieve moves translationally. The frame design of this sand sieving machine uses square profile steel 40 mm x 40 mm with a thickness of 2 mm. The box profile steel is designed so that it becomes the support of several machine components including the sieves, the dimensions of the frame are 100 cm long, 70 cm high and 70 cm wide. The calculation results obtained that the shear stress that occurs on the shaft is smaller than the allowable stress. The sieving machine design uses a belt transmission and two pulleys to reduce the motor rotation to 509 rpm, this rotation is then converted into translational motion to move the sieve with a speed of 2.34 m/s.

Permasalahan yang dihadapi mitra atau petani nilam khususnya di Desa Aoma Kecamatan Wolasi Kabupaten Konawe Selatan Provinsi Sulawesi Tenggara adalah belum tersedianya teknologi tepat guna dalam bentuk mesin pencacah nilam, masyarakat desa saat ini masih menggunakan alat manual atau tradisional seperti parang yang dimodifikasi untuk mencacah nilam, sehingga memerlukan waktu yang lama dan tenaga yang besar dalam pengolahannya. Permasalahan lain juga ditemukan bahwa pengetahuan masyarakat desa Aoma tentang teknologi tepat guna, baik dari segi desain mesin, cara pembuatan, pengoperasian, dan perawatan mesin yang sangat minim. Solusi yang diberikan pada kegiatan pengabdian ini adalah membuat mesin pencacah nilam dan selanjutnya melakukan pengenalan dan penyuluhan teknologi tepat guna alat pencacah nilam. Hasil dari kegiatan ini adalah desain dan pengenalan mesin pencacah nilam dan bimbingan teknis kepada mitra, sehingga petani atau masyarakat tidak lagi menggunakan alat manual untuk mencacah nilam, dengan mesin ini diharapkan petani dapat meningkatkan hasil produksi nilam yang siap untuk diproses ke penyulingan minyak nilam. Dengan adanya model mesin pencacah nilam dan bimbingan teknis maka harapan kedepannya masyarakat desa Aoma dapat meningkatkan produksi nilamnya dan menjadi masyarakat produktif secara ekonomi.

Technological advances in measuring instruments provide convenience in carrying out the work of measuring an object. But on the other hand, these advances require skilled operators so that they can be applied to the object being measured. The purpose of this service activity is to increase the knowledge of teachers and students in recognizing various measuring tools to increase their competence in the use of measuring tools. The method of implementing the activity uses an approach to theoretical exposure, direct demonstration and practice, discussions, and questions and answers that are directly related to measuring instruments including solar power meters, viscometers, micrometers, thermometers, tachometers, torques, welding gauges, dial indicators, and anemometers. The results achieved from the implementation of this community service activity, teachers and students gain knowledge of various types of measuring instruments and how to apply them to various objects being measured.
