We investigate rainfall variability in Indonesia using the Empirical Orthogonal Function (EOF) method. The analysis starts by taking three main modes of EOF results, namely EOF1, EOF2, and EOF3. The EOF1 region is southern Indonesia, from southern Sumatra to Timor Island, parts of Kalimantan, parts of Sulawesi, and parts of Irian Jaya. The EOF2 region is located in northwestern Indonesia and includes the northern part of Sumatra and the northwestern part of Kalimantan. The EOF3 region covers Maluku. This study aims to analyze the annual and inter-annual variability of rainfall in anticipation of the threat of hydrometeorological disasters. Based on the correlation value of the principal component (PC) with the dipole mode index (DMI) and Niño3.4 index, it has a period similar to El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). Rainfall in Indonesia is very sensitive to sea surface temperature (SST) in the southeastern Indian Ocean and the central Pacific Ocean, which means that rainfall patterns in Indonesia can change significantly if SST in the region changes.

As is known, the impact caused by El NiÃ±o Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) can reach extreme levels, especially rainfall in Indonesia. So, updating information on events and cycles of these phenomena is essential. Using Sea Surface Temperature (SST) data spanning the previous 84 years (1940â€“2023) from ERA5, we examined Sea Surface Temperature Anomalies (SSTA), which serve as a predictive tool for ENSO and IOD events. Apart from that, in this research, SSTA variance analysis was also carried out using Wavelet. The analysis results show several Positive IOD-Like events (1943, 1944, 1977, 1996) and Negative IOD-Like (1985, 1992, 2016). Apart from that, the results of this research also show that El NiÃ±o in 2002/03 coincided with Negative IOD in 2002. The results of Wavelet analysis show that the SSTA DMI variance experienced increased activity in the periods 1940-1968, 1969-1991, and 1992-2023. The Wavelet analysis also shows that ENSO activity increased in 1970-2000 and decreased again in 2000-2023.

Traditional fishermen in Surodadi Village face productivity constraints due to their reliance on conventional fishing gear and the lack of post-harvest facilities. This community service program offers a solution through the planned implementation of Internet of Things (IoT)-based Robotic Ship Fishery (RSF) technology and the construction of cold storage infrastructure. The implementation method uses the Participatory Rural Appraisal (PRA) approach, encompassing socialization, technical and managerial training, and hardware engineering, and involves 20 fishermen as target partners. The results indicate that the RSF prototypes are currently undergoing functional laboratory testing, while the construction of the 100 kg capacity cold storage is in the physical development phase. This intervention has significantly improved human resource cognitive capacity, with posttest evaluations showing that 100% of partners (20 people) understand the function of navigation technology for fuel efficiency and 93.3% (19 people) understand cold chain management. It is concluded that the program has successfully established a foundation for human resource readiness and a paradigm shift toward modern, independent fishery businesses. However, the real economic impacts will require monitoring following full implementation of the technology.

In the Indonesian archipelago, boats play a major role in people's daily mobility. In the realm of transportation, especially on sea vessels, it is crucial to keep an eye on the circumstances and state of affairs when traveling long distances. The objective of this study is to use an optocoupler sensor based on the Internet of Things (IoT) and a real-time monitoring technique to track the speed of an electric boat. This instrument can be tested using three different treatments: low-level gas, medium-level gas, and high-level gas with five repetitions. Motor speed was measured at 938 Rpm with a Knot difference of 0.7 utilizing XSpeed and an optocoupler sensor for low-speed measurements. Using an optocoupler sensor and XSpeed, the medium speed tests yielded a motor speed of 1205.6 Rpm and a Knot difference of 1.7. Using an optocoupler sensor and XSpeed, high-speed measurements yielded a motor speed of 1985.4 Rpm and a Knot difference of 1.2. Because the Blynk application may display data of both boat speed and motor rotational speed, readings obtained from the optocoupler sensor yield higher accuracy than those obtained from the comparison application XSpeed

Induction motors are widely used in the industrial world because they have many advantages, including construction that is very simple and strong, cheap, has high efficiency, quite good power factor, and maintenance is easier. Besides the advantages of induction motors also have weaknesses, one of the disadvantages of an induction motor is not being able to maintain its speed constantly if there is a change in load. If there is a change in load, the speed of the induction motor will decrease. One method of regulating the speed of an induction motor developed in addition to vector control is the Direct Torque Control (DTC) method. The DTC control technique allows direct and separate flux and torque settings and can be done without using a speed sensor. The estimated rotor rotation, torque and flux is carried out by the DTC which is inputted with stator voltage and current. To achieve the desired flux and torque estimation is used as feedback on the control system. In this final assignment, the speed regulation of the induction motor will be simulated using the DTC method using Matlab. The results obtained through the simulation show the length of time to reach the reference speed for speeds of 500rpm and 1000 rpm is around 0.5 seconds. Keywords : Induction motor, Direct Torque Control, Matlab.

Industrial sterilization is a very important problem. Ozone is a powerful oxidizer that can function for sterilization and is environmentally friendly. Plasma DBD (Dielectric Barrier Discharge) is one of the effective technologies to obtain ozone. The ozone generator currently uses a lot of manual control operations. Manual control uses a mechanical system in the form of a potentiometer to calibrate the frequency and output of the ozone generator output, so that digitization and automation are needed to operate to replace human labor. The design of the digital ozone control generator is done using an AVR microcontroller. Programming used in this research is basic language (BASCOM), then uses a DAC (Digital to Analog Converter) system which is the output of a Microcontroller with a Weighted Binnary Resistor. The output of the microcontroller is frequency and 8 bit digital with a decimal parameter of 200. The result of automation is that the timer works for 2 hours. The greater frequency the ozone produced. At a frequency of 1500Hz the power produced is 308.58 watts with an ozone concentration of 59 ppm. Efficiency using a switching system> 90%. Keywords: Plasma, AVR Microcontroller, Ozone.
