Abstract

Indonesia is located in a tropical area and is rich in natural resources and abundant agricultural land. The technique that can save land is the hydroponic system. The hydroponic system has the disadvantage that it requires more labor and maintenance compared to tillage. This research aims to design a tool that can combine and control air pH, air nutrients, air temperature and air flow speed on hydroponic plants through the Blynk application. It is hoped that this application can make it easier for hydroponic owners to control and monitor their plants remotely. The method used in this research is a descriptive method with a Waterfall research design. Based on the research results, the results of testing the air pH sensor showed an average difference of 0.18 and testing the TDS sensor, temperature sensor and water flow sensor produced different types of air which had their own resulting values in the sensor readings. In testing the relay response, applying voltage to the relay and calculating the length of delay on the pump relay gives different times with a calculation of several seconds

Abstract

Poor weather is a common problem faced by fishermen. For example, heavy rain can cause boats to flood, potentially damaging the boat’s motor engine. This research is based on the problem, of designing a microcontroller-based automatic water pump prototype. The method used in the research is experimental, following the Research and Development (R&D) model. The prototype design uses a 12-volt battery to operate the Arduino as the automatic water pump system, with a 9-volt input voltage that has been converted using a step-down converter. Meanwhile, the water pump is directly connected to the battery. In testing the ultrasonic sensor as a water detector, an average discrepancy of 0.5 cm was recorded. The relay response test was conducted by supplying voltage to the relay and measuring the relay pump activation delay over a few seconds. The SMS-based notification system test, conducted using a Sim800L, showed an average response time of 0.6 seconds across five trials. This prototype can make the water draining process easier, saving time and energy, and improving efficiency.

Abstract

The level of electrical energy demand in an area reflects the welfare of that community. The greater the use of electrical energy, the higher the community's standard of living, followed by the public's critical attitude towards everything that happens and influences lives, including electricity services. Generally, a network's reliability level can be seen from the size of the SAIDI and SAIFI values on the PLN (state electricity company) side. The calculation and reliability analysis results of the Lhokseumawe ULP above show that the total SAIFI index value is 2.68 times/year. The SAIFI Rayon Lhokseumawe reliability index is categorized as reliable because its value does not exceed the standard set by PLN in SPLN 68-2 of 1986, namely 3.2 times/year. The total value of the SAIDI index is 45.30 hours/year. The Lhokseumawe Rayon SAIDI reliability index is categorized as unreliable because its value exceeds the standard set by PLN in SPLN 68-2 of 1986, namely 21 hours/year. There are certainly differences in infrastructure, electrical equipment, and number of customers in 1986 compared to current years; this has a different influence on electricity reliability values such as SAIDI and SAIFI.

Abstract

Capacity can be developed into amazing skills that can boost personal creativity. A person's abilities, skills, or psychomotor abilities are all related. This study aimed to assess the psychomotor proficiency of SMKN 2 Banda Aceh students. P1, P2, and P3 of the psychomotor scale were used in this study to examine imitation, manipulation, and articulation. Interviews were done as part of the qualitative research process. Both in-person and online interviews using the WhatsApp app were done by visiting the informant at school. In the odd semester of 2020–2021, the interviews' findings indicate that students' psychomotor skills in productive material are restricted to P1 or imitation. Each student receives homework assignments from the teacher as part of the learning process. This is due to the COVID-19 epidemic, which outlawed busy activities in classrooms and forced learning to continue online. Lack of action in the lab causes unskilled students, therefore the teacher employs real-world video tutorial media that the students can copy. Teachers find evaluating students' psychomotor skills challenging because they have limited resources and can only evaluate their knowledge abilities.
