Abstract

Feed is an important factor in the process of aquaculture. In addition to the accuracy of the amount of feed given, the time of administration also plays an important role in the effectiveness of the use of feed. The objectives of this researh are to minimize errors feeding, both in terms of the amount of feed given and the time of administration is by designing the wake of a tool that can provide the right amount of feed and time. A feeder fish automatically designed using a timer 0f 4 pieces, consisting 1 piece timer used to set an eating schedule, and 3 pieces of each of the other is used to set a long life electric motor driving the blower, set the interval between the electric motor driving the blower with motor electric propulsion auger, and set long-life electric motor driving the auger. The test results show that the performance of the tool fish feed spreader tool can operate in three time feeding, morning, afternoon and evening. Dosage of feed within 30 seconds can remove fish feed pellets weighing 375.2 grams for medium and 233 for small pellets. Throw distance of 2.2 m and a width of 1.70 m for the distribution of pellets being as well as the distance of the throw of 2,25 m wide and 1,68 m for the distribution of small pellets. Keywords: spreader fish feed, timer, auotomatic

Abstract

The process of draining oil is one of the processes that can affect the oil content of the frying or chips. The oil that is left in a lot of fried food or chips when stored for a long time will cause a rancid smell. Meanwhile, if consumed directly, it will affect the health of consumers because of high cholesterol levels. Most people do not know the consequences that occur if they consume excess oil. People who already know cannot do anything because the oil draining machines on the market are still quite expensive and their working capacity is limited. In the previous research, a draining machine with a tube system with a diameter of 40 cm and a height of 22.2 cm was made with an rpm of 517. Within 5 minutes this system reduce oil content from 27% to 24,65% . The data shown in strightline gaphic trend that mean the reduction oil conten is not optimal yet . For this reason, this research will be redesigned by extending the spinner axis and adding the bearings to 2 units, it is hoped that this addition will stabilize the spinner rotation, the rotation can be increased and the ability to reduce oil content increases. extending the drain axis and increasing the position of the bearing to 2, the draining machine has been able to function properly until 967 rpm rotation, from the test results for draining the cassava chip oil, within 5 minutes, the slicer with a rotation of 598 rpm can reduce 2.29%, 727 rpm 2.93%, and 967 rpm 4.27% rotation.

Abstract

Lettuce (Lactuca sativa L.) is an economically important crop worldwide and one of the most popular species grown in indoor farming. Lettuce's fast growth and cycle make a model plant to study the interaction between plants and light. Light's influence is one of the fundamental environmental factors for plant growth and development. Light-emitting diodes (LEDs) have higher light efficiency and wear efficacy, leading to a reduction in associated heating compared to other artificial lighting sources, such as fluorescent lamps or sodium vapor lamps. This research aimed to determine the morphological response of lettuce by giving an LED light spectrum with a single colour spectrum and IOT-based temperature and humidity monitoring.  This research used a students’ t-test with a level of 5% on the mean value of the white light spectrum with a yellow light on lettuce plants. Adding LED light spectrum produces a different response to the morphological parameters. LED spectrum affected the plant height variable, where the provision of a yellow LED light spectrum increased the plant height of lettuce.
