Abstract

The telephone is a practical, easy, fast, and reliable means of communication. However, when using the telephone, problems often arise in terms of costs. The lack of control over telephone users in using pulses is one of the obstacles, because then telephone pulses do not feel a dramatic increase from the initial calculation. Telephone data recording technology that uses the DTMF (Dual Tone Multiple Frequency) method and PPI 8255 as an interface can be used to overcome this. We can use this technology application to create a tool that can monitor telephone usage time through a Personal Computer. So that by doing so, home telephones or government and private institutions are protected from spikes in credit usage. From this final project obtained a monitoring system for telephone usage through a Personal Computer both for incoming and outgoing calls in terms of data recording and usage time. This system can also limit or block unwanted outgoing telephone numbers at any time without having to stand by the phone.

Abstract

The bomb terror that occurred in various regions is very troubling, because it causes us to feel anxious when we go anywhere. Bombs which are usually made of metal must be detected by a device called a metal detector "Tanaan" which can detect the presence of metal either embedded in metal or covered in other materials other than metal such as in suitcases or bags. On this occasion a metal detector with using the "Beat Freauencv Oscillator" method. The metal detector with this method uses two oscillators, namely the search coil and the reference oscillator. Inside the search coil oscillator there is a sensor in the form of a coil of copper wire and email where the frequency of the search coil oscillator is in, will change when the sensor is on. a certain distance adjacent to the metal.While the reference oscillation, has. Is a stable frequency. When a signal with frequency. If the signal generated by the search coil oscillator is mixed (mixed) with the signal generated by the reference oscillator, a pure frequency and both frequencies will be produced which can be heard by humans. The resulting sound is like a tapping sound with a certain rhythm and is often known as a heat note.

Abstract

Plants are one of the sources of feed for honey bees to carry out their lives. Currently, the identification of honey-producing plants still needs to be carried out. This research examines the types of plant species used as a source of food for Trigona sp. bees at Royal Honey Sakah in Gianyar, Bali. Qualitative descriptive research uses observation, documentation, and direct interviews with agro-tourism owners. Royal Honey Sakah's investigation will continue until May 2022. As a result, Royal Honey Sakah provides several types of plants as a feed source for Trigona spp. bees. Red Santos (Xanthostemon novoguineensis), which has the largest population, is followed by santos lemon (Xanthostemon chrysanthus), Bidarasari (Porana volubilis), red Kaliandra (Calliandra calothyrsus), bridal tears (Antigonon leptopus), Batavia (Jatropha intergerrima), and princess's palm (Veitchia merillii). The plant produces nectar that is much needed by bees. The number of honey bees depends heavily on the availability of nectar from plants.

Abstract

Targeting the number thought in a list is a common problem in computer science and is commonly implemented with the search algorithm. Numerical math games are a big thing for all of us. One of the really challenging games is targeting the number thought by the opponent. Therefore, the purpose of our study is to find the desired number through the binary search algorithm. For this study, we developed a pseudocode in the Python programming language, which gives the desired result followed after several successful steps. Our study results show that the algorithm was very efficient in solving the problem of finding the intended natural.
