Abstract

The BSF fly (Black Soldier Fly) commonly known as the black soldier fly is an insect whose larvae are widely used as animal feed or commonly known as a maggot. BSF flies only need to drink, and do not eat. BSF fly feeding should be given regularly based on the ambient temperature around the cage. At this time, BSF fly breeders tend to have a busy and congested schedule so the cage spraying schedule is neglected. In addition, human negligence factors such as laziness and forgetting also make the spraying schedule irregular. Spraying of the cage was done manually using a plant sprayer. Therefore, research was conducted on the design of a microcontroller-based BSF fly drinking system. This system can perform automatic spraying of BSF flies based on the high and low temperatures around the cage, as well as provide notifications to the telegram of the BSF fly owner. Based on the study's results, this system detects the temperature around the cage using a DHT22 sensor and then sprays drinking BSF flies with the help of a DC pump. This system can be connected to the internet to send notifications that the cage has been sprayed via the telegram application of the cage owner.

Abstract

The use of technology is fundamental in the digital era. Adjustment and transformation are essential activities to keep up with technological developments. One of the uses of technology is product marketing and promotion. Sanjai Tourism Village, located in Bukittinggi City, is one of the villages where marketing and promotion of tourism products are still carried out using conventional promotional methods such as through newspapers, radio advertisements, posters, and distribution of brochures. This method is still limited and cannot reach a broader scope. Therefore, to compete in the digital era, there needs to be a transformation of promotion and marketing of tourism products through the internet media using a website. Information about promoting and marketing tourism products can be done digitally and online using a website. The results of advertising and marketing tourism village products by utilizing the website can be spread and known to the public with a broader reach. Therefore, in the community service activities of the Unand Computer Engineering Department, the Sanjai Tourism Village website was built with a method consisting of several stages, such as coordination, surveys, design, website implementation, improvement, and submission of the website to Sanjai Tourism Village. Each stage has been carried out, and a website has been produced with features such as a homepage, profile, tourism products of various fields, news and activities, and contacts.

Abstract

Electrocardiograph (ECG) is a recorder of human heart signals with signal output on a monitor or graph paper. The ECG records the measurement of the electrical activity of the heart from the surface of the body by a set of electrodes that are installed in such a way that reflects the tapping point activity. The pattern of ECG output signals in one heartbeat produces a pattern with a peak point P, Q, R, S and T or QRS complex. ECG signal waveform results were analyzed using Learning Vector Quantization (LVQ) Artificial Neural Networks, and grouped into two classes, namely normal and abnormal heart patterns. The normal heart condition that is trained is a medically normal heart categorized as healthy as 10 data, while an abnormal heart (Heart, Coronary Heart, and Aortic Regurgutation) is 20 data. The LVQ method recognizes the input pattern based on the proximity of the two vectors, namely the vector of the input unit or neuron with the weight vector produced by each class. Online LVQ identification (using ECG) recorded from 25 direct trials resulted in 80% accuracy.

Abstract

People in general have a desire to live a healthy life. One way to keep health is by consuming herbal drinks, one of them is known as jamu. Jamu which is commonly found is "jamu gendong" which is a home-based herbal product that is marketed in the form of liquid in the bottle. When buying jamu, the seller will mix various types of jamu by pouring jamu from each bottle into a glass according to the buyer's request. However, mixing several types of jamu is carried out using the seller estimate, so the dosage of several types of jamu to the glass will vary according to the pouring. The purpose of this research is to make a arduino Mega based automatic jamu beverage mixing system. This system uses an LDR sensor to detect the presence of a glass with a resistance value read by an LDR sensor is > 500 ohm and a DC motor can move by the stirrer. The selection of the jamu menu's is done by pressing the keypad button from the code '1' to the code '8'. After the menu is selected, the jamu will flow to the glass and the volume of jamu will be calculated using a water flow sensor that uses multiplier values. For the volume of 150 mL is used to multiplie factor 3.7 , for the volume of 100 mL is used to multiplie factor 2.9 , and for the volume of 50 mL is used to multiplie factor 1.2.
