This cracker dryer is made considering that there are still many cracker industries that use solar thermal energy directly to dry raw crackers before the frying process, so that the cracker production results will decrease due to inefficient drying process, therefore all obstacles are always experienced when using energy sunlight can be overcome by using a cracker dryer using gas (LPG). This cracker dryer has dimensions of length 550 mm x width of 450 mm x height of 1000 mm and size of drying rack with a length of 500 mm x width of 400 mm x height of 25 mm. This tool has 4 drying racks with a capacity of each rack 1.5 kg. This dryer uses the principle of convection that is utilizing heat energy generated from the heat of the fire produced through a gas-using stove (LPG), the radiated fire produces heat that enters the drying cabinet. Hot air is locked in a drying room, so that the heat can help the drying process of crackers

In this day and age people decorate homes with flower pots and many models of flower pot place creations. Usually the place to put flower pots in the form of a circle and to make a circular iron is made manually requires energy and a long time. A bending machine is needed to make concrete iron circle creations. The aim of this research is to produce a rotary bending machine that is able to work efficiently in forming a concrete steel circle. The method used in this study is a practical method that is doing machine design and continued with the manufacture and field testing. The working principle of this machine is to use a motor that functions to move the Gearbox and continue the rotation to the shaft, then the shaft rotates and the bending mall rotates and makes the steel concrete come round and circular. The conclusion is (a). This concrete steel rotary bending machine has dimensions of 550 mm x 550 mm x 1000 mm with an electric motor drive power source (b). The results of the bending process using a concrete steel rotary bending machine are far more efficient than doing manual bending

Carpet washer is a machine that is used to help complete work in the laundry industry. By using this carpet cleaning machine, cleaning carpets is fast and easy. The purpose of designing this carpet washing machine is a form of innovation and creativity based on technological developments. This machine is made with an additional tube of liquid detergent to make work easier and increase efficiency. The initial method of designing this carpet washing machine is to collect data. Next is the calculation and design. The results of the design of this carpet washing machine obtained a motor power of 1.5 HP and a rotation of 1400 rpm, with a height of 1020 mm, a length of 745 mm and a width of 345 mm using a type-A belt transmission, pulleys with a diameter of 2” and 6”, a shaft diameter of 19 mm, the type of bearing used is UCF F212 type, has a cleaning brush and uses a liquid detergent tube. The design of this carpet washing machine has been made based on the correct design and calculation and can be continued for production.

Design and manufacture of coffee pulper machines have been carried out with the aim of completing the needs of the coffee farmer groups when harvesting in the Kayu Aro area, Kerinci. The steps in designing and manufacturing a coffee pulper begins with a literature study, design and calculation, the process of making the tool and ends with testing the tool. Engineering drawing design is done by modeling in SolidWorks software. Coffee peeler machine with a capacity of 4 kg/min, with a machine size of 730 mm x 320 mm x 1040 mm, using an electric motor 1 HP 1420 rpm, with a frame using an elbow profile 40 mm x 40 mm x 3 mm. The transmission system uses an electric motor with an initial rotation of 1420 rpm to 364.6 rpm. In the 2 pulley component D = 74.6 mm and 290.5 mm, V-belt type B No.52, 1 solid shaft D = 25 mm. Initial test results using 2–5 kg of wet coffee beans take 30.07–77.20 seconds, and the skin has separated from the beans cleanly. These results show that the engine capacity is 235.62 kg/h, so that the desired target is met with relatively low operating costs. The existence of this tool will be able to help the process of separating the skin and coffee beans, so that the quality of coffee production will increase.      Keywords:  coffee, coffee machine, design and construction, farmer groups

Kanagarian Salo Kec. Baso Kab. Agam memiliki beberapa peternakan puyuh yang dikelola secara mandiri. Berdasarkan survey yang  dilakukan pada awal 2020 di peternakan puyuh kanagarian Salo, pakan puyuh diaduk secara manual menggunakan skop sehingga hasil adukan tidak merata ditiap bagian. Pengolahan pakan yang baik sangat berpengaruh pada produksi telur puyuh. Pakan yang baik memiliki komposisi pengadukan yang merata di setiap bagian ransum, sehingga puyuh mendapat gizi sesuai kebutuhannya. Berdasarkan permasalahan tersebut sangat perlu dibuatkan mesinpengaduk pakan unggas. Tujuan pengabdian masyarakat ini adalah menyediakan mesin pengaduk pakan ternak puyuh kapasitas 400 kg untuk peternak di Kanagarian Salo. Diharapkan proses pengadukan pakan menjadi lebih efektif dan efisien. Metoda yang digunakan untuk menyelesaikan permasalahan mitra adalah adalah rancang bangun alat pengaduk pakan yang aplikatif berdasarkan kebutuhan mitra dan sosialisasi cara pemakaian mesin pengaduk. Hasil kegiatan pengabdian ini adalah tersedianya mesin pengaduk pakan puyuh kapasitas 400 kg untuk peternakan puyuh di kanagarian salo dan pemahaman peternak dalam pengoperasian mesin. Kata kunci : pakan unggas, pakan puyuh, mesin pengaduk, tingkat campuranhomogen ABSTRACT Kanagarian Salo Kec. Baso Kab. Agam has several independently managed quail farms. Based on a survey conducted in early 2020  quail farm in Kanagarian Salo, the quail feed ingredient was stirred manually using a shovel  that produce Non-homogeneous mix. Good feed processing is very influential on the production of quail eggs. A good feed has an even mixing composition in every part of the ration, so that the quail gets the nutrition their needs. Based on these problems, a poultry feed mixer machine is needed. The method used to solve the problems is the design of an poultry feed mixer machine based on the needs of partners and socialization of how to use the mixer machine. The result of this activity is the availability of a poultry feed mixer machine with  400 kg capacity  for quail farms in Kanagarian Salo and the understanding of farmers in operating the machine.
