Abstract

The design and manufacture of corn seeding planting machines with this cultivator system is one of the simplest and more productive technological innovations to help the community of entrepreneurs and farmers in completing the work of planting corn seeds in large areas. Maize cultivation can still be developed and become an excellent effort in Dairi Regency to see the area and the land available and supported by the fertile climate and soil as well as the people who like to plant maize. This is also offset by an increase in corn prices of maize commodities. To improve the corn production process, it requires a machine / tool that can plant corn seeds efficiently, a more productive way of working, and greater production capacity. The corn seed planting machine consists of several standard components such as: 1) 4-step gasoline motor, 1: 50 reducer speed, pegs, pulleys, belts / belts, chains, gears and bearings, 2) key components done by machining process that is: cradle frame, driving shaft, blade / blade, screw arm, screw cultivator. The machines / equipment used in the construction process, and the main components are: machine, machine, machine, hand grinding machine, deep thread tap, and welding transformer. From the design and fabrication process to the process start from the process of making the main component and assembling process that is done, hence produce one unit of planting plant of corn seed with cultivator system according to the desired design with result of production capacity test 258 seed / minute.

Abstract

This study were to find out the mechanical properties (tensile strength, elongation break, and elastic modulus) and morphology of the polyethylene and SIR-20 blends by using a used tire filler. The method used by adding a used tire powder (80 mesh) as a filler on a mixture of recycled SIR-20 and polyethylene (PE) rubber. The composite preparation was carried out by mixing (PE) and SIR-20 rubber as a matrix, polyethylene malaeic anhydride (PEMA) as a compatibilizer, and Sulfur as cross link agent by adding filler (0, 10, 20, 30) phr, in Internal Labopastomil with temperature 1800C and rate of 60 rpm for 14 minutes. The results showed that the mechanical properties decreased with the rise of used tire powder, while the morphological result of the homogeneous mixture.

Abstract

Corncob is one of the organic waste which so far still not used as a product that has added value. It turns out that corn cobs can be utilized into liquid smoke which is useful for environmentally friendly food preservatives. In this research, the raw material used is corncob waste as liquid smoke manufacture. The method used is pyrolysis method using pyrolysis reactor, by burning and heating on the furnace which will produce smoke and then it will be condensed (water vapor in the air condenses from gas form, back to liquid) into liquid smoke or liquid smoke. The result of rendeman characterization is 4.3-5%, liquid smoke pH 2.8-3.0 and liquid smoke test applied to mujair fish can survive for 20 days.

Abstract

Sudirman Street intersection is part of the main road in the city of Pekanbaru where the activity in this road area is quite besar.ruas this road is a transportation path that is used by the community if they want to head office and school in Pekanbaru city. Thus, it is often delayed because the volume of vehicles passing through the intersection especially from the west (Jalan Tuanku Tambusai) is quite dense, resulting in slowing and accelerating vehicles that veer at intersections and can cause conflicts from other vehicles that cross the intersection. Prior to the first research, measurements were taken to collect the width of the approach data on the intersection. The data taken were all vehicles passing through the intersection of either the left, straight, or right turn, and the length of the queue. The research was conducted for three days on Saturday (05/30/2011), Monday (02/05/2011), with the morning observation hour (06.00-08.00) WIB, noon (12:00 to 14:00 pm ), afternoon at (16.00-18.00). The data is then processed by Method MKJI 1997. Based on the evaluation that has been done, the length of queue and degree of saturation at the intersection is very high. To overcome this, three alternative designs are green time design, road geometry design, and road geometry design along with green time design. The result of the calculation after 3 alternatives shows that the degree of saturation in each approach has met the acceptable value of 0.75. The right handling solution done today is with the green time design alternative.

Abstract

The AICAR building is part of the waste water system located in Lubuk Gaung - Dumai. Analysis and design of this AICAR uses reinforced concrete material for its structural material. Planning uses the extreme conditions of the water load / hydrostatic load variable. The selection of water load modeling becomes the key word in the analysis and design of the building mentioned above. The hydrostatic load causes the distance pattern from the pile to be limited to a minimum pile distance of 2.57 m x 3.44 m. The reinforcement on the wall has a denser distance than the floor plate reinforcement.

Abstract

PT. XYZ is a national private company engaged in thermorforming plastic packaging industry and injection molding. Plastic thermoforming produced are types of printing (plastic cup) and plastic cup (clear plastic cup) while for plastic injection molding product is loly (plastic tube). So far in calculating the cost of production of PT. XYZ uses traditional cost calculations where the distribution of overhead (Fixed Cost) is evenly distributed for all product types although the process is different because the traditional cost calculation does not calculate the cost of production in detail. Based on the background, the authors use Activity Based Costing method in the company's financial calculations. From the calculation, the average cost of production obtained by using activity based costing method for clear cup is Rp.21 / gr, for cup printing Rp.12,07 / gr while the average cost of production of cup lolly is Rp. 34.23 / gr. The average cost of production obtained by using traditional method for clear cups is Rp.19,55 / gr, for cup printing Rp.19,55 / gr while the average production cost of cup lolly is Rp. 19.55 / gr. The cost of clear cups production using ABC method and traditional method with difference is Rp.1,45 / gr, the difference for cup printing is Rp.7,48 / gr while for cup lolly the cost difference is Rp.14,68 / gr. Products that undercost is cup printing, while the overcost is a clear cup and cup lolly

Abstract

Vibrations on the floor plates of multi-storey buildings can occur due to excitation arising from the activities of human activity such as running, dancing and other sports. Vibrations become excessive on the multi-storey building floor system, and this vibration is not related to the building's safety factor, but only in contact with the user's inconvenience. Excessive vibrations occurring in the system of floor plate structure may occur in multi-storey buildings that have (1) lightweight floor structure systems due to the use of high-grade building materials or composite materials on building structural elements such as beams that allow the design of the elements of the structure (2) long-stretched floor plate system with low structural stiffness in which the dominant natural floor frequency tends to be low and close to excitation frequency, and (3) the floor plate structuring system has a low damping value due to the use of the partition and fewer furniture items. The three things mentioned above cause the vibration on the floor plate system to be excessive and cause discomfort and disruption for users of the building. Vibration on the floor plate system causing the discomfort may occur on a floor plate system that has a vibration frequency (fn) of less than 8 Hz. To reduce the vibration frequency (fn) of the plate system must be increased to approximately 8 Hz natural frequency. The use of WF-shape steel structure used is WF 200, capable of increasing the damping value in the system of floor plate structure which is observed in one of the school buildings in Medan.
