Abstract

At this time in the process of sweeping the road still using traditional tools by janitors, for example broom sticks. One of the technologies that began to develop was the Street Sweeper machine. This Street Sweeper is a tool to help alleviate the work of janitors in terms of road sweeping. Sweeping the highway using the Street Sweeper is one of the main steps to accelerate the process of sweeping the highway with rapid traffic flow. The working principle of this machine is by utilizing thrust from humans, by means of a machine being pushed and directed to the garbage scattered on the road. Therefore it is very appropriate to use Street Sweeper to sweep the road compared to using manual tools because it can save work time

Abstract

The pump is a device that can lift water from a lower height to a higher place, but because there are many pumps in the market that use electricity as a power plant and the selling price is quite high for rural communities, an appropriate pump is needed and cheap. Hydram pump is one alternative, where the workings of this tool can raise the water to a higher place with energy or power that comes from the water itself. Making Hydram pumps itself is relatively inexpensive, simple and durable. Hydram pumps are very popular because they work without using energy, so it is suitable for use in villages that do not have electricity. The purpose of this study was to determine the effect of the height of the incoming water and the diameter of the outlet pipe on the height of the outlet water at the hydram pump. In this study the height of the incoming water was varied as high as 0.5m, 1m and 1.5m while the diameter of the aoutlaet pipe was varied by 0.5inc, ¾ inc and 1 inc. From this experiment it was found that the height of the incoming water and the diameter of the outlet pipe significantly influence the height of the outgoing water, of the two factors most influential on the height of the outgoing water is the height of the incoming water

Abstract

Indonesia is one of the countries which has high intensity solar radiation. This is very useful in term to exploite solar radiation for drying processes. However, most drying processes are done naturally. This method has many constraints. By improvement of solar collector technology, the drying processes could be done more better. Unfortunately, most solar collectors still have many limitation due to generating high output temperature. Therefore, in this present study, the solar collector is tried to optimizing by enlarging area of frontal surface of solar radiation and increasing rate of air flow out in term to maximize the drying processes. Result shows that by flowing the air constantly (0, 122 m3/s) on 1 m2 surface area will generate output temperatur to approximately 90,2 oC

Abstract

Candlenut seeds are one of the plants that grow in Indonesia. Candlenut leaves and seeds have many benefits that are useful for human life. Candlenut oil can be used as a raw material for making varnish, paint, soap, fabric oil, resin, synthetic leather, lubricants, compost, and cleaning or polishing mixtures. Candlenut fruit has a shape ranging from oval to round, green to brownish green, with a length of ± 5–6 cm and a width of ± 5-7 cm. One candlenut contains one to three candlenut seeds. To get the candlenut seeds, they must be removed from their hard and thick shell by breaking them.So far, getting candlenut seeds has been done by breaking them manually by hitting them one by one. This is certainly not effective and takes a long time. Based on this, a tool was designed and made for breaking candlenut shells using a 2 HP motor drive. This candlenut shell breaker tool consists of a throwing part that rotates vertically, which, due to the centripental effect, throws the candlenut kernels against the wall of the breaker. The broken candlenut kernels and shells fall down into the filter section to separate the kernels and shells, then the candlenut kernels go inside. holding containers. To get the ideal launcher rotation, several speed variations were tested, namely: 1. 250 rpm, 2. 350 rpm, and 3. 500 rpm. Of the three variations of rotation, the best rotation was obtained with the shell breaking and the seeds releasing well without breaking, namely at 350 rpm.

Abstract

The beach is a comfortable place for traveling and relaxing. Therefore, the cleanliness of the beach area must be maintained for the sake of mutual comfort. Due to the lack of discipline of visitors, a lot of rubbish is piled up and piled up out of place every day. So, cleaning staff find it difficult to clean up rubbish manually. Therefore, an initial design stage is needed, then proceed with the creation of a semi-automatic beach cleaning machine or Beach Cleaning Machine to overcome this problem. In the future, cleaning the beach using this machine can speed up the cleaning process and make the work of beach cleaners easier. The working principle of this machine uses a gasoline motor as a driving source. So, when the motorbike is turned on, the machine will work automatically. Then to direct the movement of the machine an operator is needed. So, it is very appropriate to use a Beach Cleaning Machine to clean the beach compared to picking it up directly or using manual tools, because it can save work time.
