Abstract

This study analyzes tropical cyclones (TCs) in the Southern Indian Ocean from 1970 to 2022, utilizing data from the International Best Track Archive for Climate Stewardship (IBTrACS) and Sea Surface Temperature (SST) data from ERA-5. Trends are assessed with Sen's slope method. Significant TC shifts are evident. Categories 1-2 TCs have substantially reduced in number, duration, and speed, indicating an overall decline in activity. Conversely, more powerful TCs (categories 3-5) have intensified, driven by rising SST. This intensification is associated with alarming increases in the Power Dissipation Index (PDI) and Accumulated Cyclone Energy (ACE), reflecting heightened destructive potential. TCs predominantly occur during DJFM, influenced by elevated SST compared to MJJASO. Climate drivers, including El Niño-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Madden-Julian Oscillation (MJO), significantly affect TC characteristics. Elevated TC activity coincides with La Niña, neutral ENSO phases, and positive IOD events. At the same time, MJO influences are nuanced, leading to a slight TC activity decline, potentially due to data limitations in specific MJO phases. This study offers vital climatological insights into evolving TC risks in the Southern Indian Ocean, aiding agencies and decision-makers in understanding TC-related risks in the region.

Abstract

This research aims to identify and document the local food security system in the Semende traditional community based on tunggu tubang indigenous knowledge. The study was conducted in 3 districts of Muara Enim, South Sumatra, involving 81 people from 5 villages practicing the tunggu tubang custom. Using a mixed method, the research took place from July to August 2023.The findings revealed that while tunggu tubang adherents still inherit rice fields and agricultural land, some no longer own rice fields. Inheriting rice fields has led to sufficient food availability but does not guarantee good food security. 50.6% of respondents experienced mild food insecurity due to the traditional sandwich generation where they have to support their parents and closest family. Despite this, most children (56.6%) showed good nutritional status. This research identifies and documents the local food security system in the Semende traditional community. It reveals the importance of tunggu tubang in maintaining food availability but acknowledges the challenges in achieving food security. The findings provide valuable insights for developing educational initiatives to address climate change and food security

Abstract

This research aims to achieve male sex reversal in Nile Tilapia (Orechromis niloticus) of the red NIFI strain through high-temperature incubation during the embryonic or pre-swimming larval phase. Larvae resulting from the natural mating of red NIFI strain broodstock were incubated under temperature treatments of 31oC, 33oC, 35oC, and a control group (<30oC), each with three replicates. Temperature regulation was facilitated using a heater.  During the initial 3 hours of incubation, the heater was turned off for 6 hours, followed by another 3 hours of incubation with the heater on. This pattern was repeated daily until the larvae began to swim. The treated larvae were then reared for 90 days. Thirty specimens from each replicate were identified for gender using the squash acetocarmine method. The study results indicated that temperature differences significantly influenced (p<0.05) the sex ratio of Nile tilapia in the red NIFI strain. The highest proportion of males was achieved at 33oC, at 73.33%, and 35oC, at 64.43%. There were no significant differences (p>0.05) in fry survival rates at 7 days and after 90 days of rearing.

Abstract

The pitot tube is a component in the fuselage to measure the pressure generated by air movement or wind, while the placement of the pitot tube is usually on the wing. A trivial thing that can be fatal is that before flying, sometimes the pilot/flight instructor neglects to remove the pitot tank cover. This negligence resulted in the malfunctioning of the Air Speed Indicator (ASI), Vertical Speed Indicator and Altimeter. Appropriate technology in the form of a pitot tube cover with a warning using an ultrasonic sensor with the support of artificial intelligence technology using Arduino has been applied to the Piper Seneca V aircraft to prevent negligence in removing the pitot tube cover before flying. The Piper Seneca V has been chosen as the object of the application of technology because the Piper Seneca V type aircraft is of the low wing type so that the pitot tubes are not visible when not inspecting the underside of the aircraft's wings. During 30 days of testing with 12 hours of testing time each day and exposure to different temperatures and humidity each day, both battery life and component resistance can be ensured that they are still in optimal conditions. During testing in the simulation room, the tool worked well with a 1 meter object detection configuration. Using a 3.7 volt battery with a storage capacity of 1600 mAh can make the device last for 4 days with 2 hours of recharging time.
