AbstrakAdonan kerupuk merah merupakan campuran dominan tepung dan air yang biasanya diaduk secara tradisional menggunakan tangan. Kajian ini menumpukan perhatian pada rancang bangun alat pengaduk yang dapat memproses adonan secara mekanik. Pada rancang bangun digunakan 2 buah sirip pengaduk yang terpasang dikedua sisi poros dengan putaran motor 1450 rpm. Speed reducer mereduksi putaran dengan rasio 1:30. Alat pengadukan adonan juga dilengkapi dengan proses pencetakan yang menggunakan screw sebagai pendorong adonan ke cetakan yang terpasang satu poros dengan sirip pengaduk. Rancang bangun menghasilkan putaran yang dikeluarkan ke poros pengaduk sebesar 24 rpm, yang mampu memproses adonan dalam sekali pengadukan seberat 87,53 kg berupa campuran tepung dengan indukan. Dengan adanya alat pengaduk adonan dan pencetak kerupuk merah ini  dapat mengurangai pemakaian waktu dan meringankan kerja operator pada saat produksi. Sehingga dengan menerapkan alat bantu ini dapat meningkatkan jumlah produktivitas sekaligus meningkatkan pendapatan masyarakat. Kata kunci: adonan, kerupuk merah, sirip pengaduk,  AbstractThe red cracker dough is the dominant mixture of flour and water which is usually stirred traditionally by hand. This study focuses attention on the design of a mixer that can process a dough mechanically. In the design, 2 stirring fins are used which are attached to both sides of the shaft with a motor rotation of 1450 rpm. Speed reducer reduces rotation by a ratio of 1:30. The dough stirring device is also equipped with a molding process that uses a screw to propel the dough to the mold, which is attached to one axis with the mixing fin. The design produces a rotation that is issued to the stirring shaft at 24 rpm, which is able to process the dough in one stirring weighing 87.53 kg in the form of flour mixture. It is hoped that the benefits from the design of the dough mixer and red cracker molders will reduce time usage and ease the work of the operator during production. So that, by applying this tool can increase the amount of productivity while increasing people's income.  Keywords: dough, red cracker, strirring fins.

Waste plastic mounting, but can be recycled into other products in the form of granules before further processed into pellets and seed injection molding process produces products such as buckets, plates, bottles and other beverages. To be processed into the required form of granules of plastic thrasher. Though so small plastic recycling industry is still constrained in plastic enumeration process because the machine used was not optimal ability. The purpose of this research is the development of the system thrasher plastic crusher and cutter cylinder-type reel and technical evaluation. This study was conducted over two years, the first year the design and manufacture of machinery, the second year is a technical evaluation of the engine, engine performance improvements and economic analysis of granular plastic products.From the results obtained engine design capacity of the machine ± 350 kg / h, the engine size is 50 cm x 120 cm x 30 cm, power motor of 10 HP at 1450 RPM rotation with 3 phase. Some of the major components of the engine that is, counter crusher unit consists of two counter rotating cylinders opposite, counter shaft size Ø 4 cm x 58 cm, blade chopper Ø 17 cm x 2 cm with the number of teeth / blades 7 pieces and the number of blades along shaft 7 pieces, buses retaining Ø 10 cm x 2 cm. Counter-cylinder unit consists of a reel-type cutter counter shaft size Ø 4 cm x 90 cm, the middle shaft mounted cylinder with Ø 17 cm x 40 cm as the holder of the chopper blades. Chopper blade consists of 4 pieces with a size of 40 cm x 2 cm x 4 cm with ASSAB materials. Furthermore, as the blade retaining bedknife shear force of the blade chopper, upper frame, lower frame, strainer, funnel entry, exit funnel, and the drive unit consists of an electric motor, reducer, belts, pulleys and 2 pieces of gear transmission. The results of performance testing machine crusher round cylinder 75 RPM and 1450 RPM reel-type cutting machine capacity ± 300 kg / h on the filter hole Ø 1.5 cm, with a 80% grain uniformity.

The Coefficient Of Friction

The experimental investigation of reciprocating motion between the aluminum doped crumb rubber /epoxy composite and the steel ball has been carried out under Reciprocating Friction Tester, TR-282 to study the wear and coefficient of frictions using different normal loads (0.4Kg, 0.7Kgand1Kg), differentfrequencies (10Hz, 25Hz and 40Hz).The wear is a function of normal load, reciprocating frequency, reciprocating duration and the composition of the material. The percentage of aluminum presents in the composite changesbut the other components remain the same.The four types of composites are fabricated by compression molding process having 0%, 10%, 20% and 30% Al. The effect of different parameters such as normal load, reciprocating frequency and percentage of aluminum has been studied. It is observed that the wear and coefficient of friction is influenced by the parameters. The tendency of wear goes on decreasing with the increase of normal load and it is minimum for a composite having 10%aluminum at a normal load of 0.7Kg and then goes on increasing at higher loads for all types of composite due to the adhesive nature of the composite. The coefficient of friction goes on decreasing with increasing normal loads due to the formation of thin film as an effect of heat generation with normal load.
