Overview of the Research (Heading 2) According to Zarmawis (2009), Indonesia's marine potential, which includes coastal areas, is derived from marine biological economic resources that can be recovered.These resources include seaweed, pearl oysters, reef fish (cultivated or raised in marine environments other than ponds), capture fisheries, and the marine biotechnology industry, which has a total estimated value of US$ 71,935,651,400 annually.2. Goal of the Research (Heading 2) In order to ascertain the possibility of seaweed production in the sea waters of the Denpasar-Bali assault, this study attempts to measure and characterize the distribution of sea surface temperatures both before and after the Covid-19

LITERATURE REVIEW
With a total area of 8,300,000 km2, comprising 6,400,000 km2 (77.11%) of sea waters and 1,900,000 km2 (22.89%) of land, Indonesia boasts a coastline that stretches 110,000 km (BIG 2017in PERPRES, 2019).The food development plan of Indonesia should be distinct from that of the United States and Australia, two nations with greater landmasses but smaller marine areas.
Indonesia should concentrate on managing the potential of its waterways to promote national food security and contribution to global markets, as the country's sea area accounts for about two thirds of its total area.The majority of the food that comes from waterways comes from sources of fibrous animal protein.Less than 1% of Indonesians consume fibrous foods made from seaweed, which is far less than the 20% of people in other nations like Japan that utilize seaweed as their primary source of fibrous foods.(PERPRES, 2019).
Seaweed farming is another kind of aquaculture in the fisheries industry that has potential for development in Indonesia, according to Aslan (1998).The production of seaweed is crucial to efforts to boost fisheries output in order to meet demands for food and nutrition, as well as those of the domestic and international markets.It also helps to create jobs, improve the welfare and income of fish farmers and fishermen, and preserve aquatic biological resources.
PERPRES, the year 2019 In addition to providing a food source, seaweed, particularly in Indonesia's coastal regions, helps to alleviate poverty among communities.With 261.9 million people living there as of 2017, Indonesia needs a lot of protein, carbs, and fiber.This explains the great desire for seaweed to be extensively cultivated in order to use it as a lever for the economic development of coastal areas, which are home to about 60% of Indonesia's total population.

METHODOLOGY 1. The Heading 2 MODIS (Moderate Resolution Imaging Spectroradiometer)
MODIS is one of the primary instruments carried by the spacecraft Terra (previously known as EOS AM-1) and Aqua (formerly known as EOS PM-1)., or Moderate Resolution Imaging Spectroradiometer.Terra crosses the equator from north to south in the morning due to the timing of its orbit, whereas Aqua crosses it from south to north in the afternoon.
In order to monitor the whole Earth's surface, Terra MODIS and Aqua MODIS collect data in 36 spectral bands, or sets of wavelengths, every one to two days (see to MODIS Technical Specifications).These data will improve our understanding of the global dynamics and processes occurring in the lower atmosphere, on land, and in the oceans.MODIS has significantly contributed to the development of validated global interactive Earth system models that can accurately predict global change, assisting decision-makers in protecting our environment.
The MODIS instrument has a high radiometric sensitivity (12 bit) and 36 spectral bands with wavelengths ranging from 0.4 µm to 14.4 µm.The solutions have very little out-of-band reaction and are tailored to the particular requirements of the user base.29 bands are taken at 1 km, and five bands are taken every 500 m., and two bands at a notional resolution of 250 m at the nadir.Using a 2,330-kilometer swath and a ±55-degree scanning pattern at the 705kilometer EOS orbit, global coverage is achieved every day or every two.
The Scan Mirror Assembly is powered by a motor encoder that is designed to run at 100% duty cycle for the duration of the instrument's six-year design life.It scans ±55 degrees employing a continually rotating, double-sided scan mirror.The optical system focuses light onto four refractive objective assemblies using an off-axis afocal telescope with two mirrors.These assemblies are one for the VIS, NIR, SWIR/MWIR, and LWIR spectral areas, and collectively they cover a 0.4 to 14.4 µm spectral range.
Two HgCdTe Focal Plane Assemblies (FPAs) have their 20 infrared spectral bands reduced to 83K by a high-performance passive radiative cooler.A unique photodiode-silicon readout technique offers exceptional quantum efficiency, low noise, and excellent dynamic range for the visible and near infrared.The two specialized electronics modules, The modules Space-viewing Analog (SAM) and Forward-viewing Analog (FAM), respectively, the analog programmable gain and offset, and the FPA clock and bias circuits, are situated close to the FPAs.The Main Electronics Module (MEM), the third module, is in charge of power, control systems, telemetry and command, electronics calibration, and control systems.
The system includes four on-board calibrators: a v-groove Blackbody (BB), a spectroradiometric calibration assembly (SRCA), a solar diffuser (SD), and a solar diffuser stability monitor (SDSM).It has a glimpse of space as well.
The first MODIS flight instrument, the ProtoFlight Model, or PFM, is installed on the Terra (EOS AM-1) satellite.On December 18, 1999, Terra was successfully introduced.The MODIS flying instrument number two is flying Model 1, or FM1.It is a part of the Aqua (EOS PM-1) spacecraft, which was launched on May 4, 2002, successfully.These MODIS instruments offer a unique window into the phenomenology of the land, atmosphere, and ocean that will be of great service to a broad and varied global user base.
The MODIS instrument has been developed since the middle of 1995, when the Engineering Model (EM) was completed.Since then, two spaceflight units-the Protoflight Model (PFM), housed aboard the Terra satellite, and the Flight Model 1 (FM1), housed aboard the Aqua satellite-have been completed and launched.Terra made its debut on December 18, 1999, and Aqua debuted on May 4, 2002.
The ultimate in aerospace hardware engineering for remote sensing are the MODIS sensors, which Santa Barbara Remote Sensing built in compliance with NASA specifications.The MODIS instruments were designed with the following subsystems and capabilities in mind.Click on the indicated links for more thorough technical explanations of each subsystem.
A single device with the ability to photograph the land, sea, and atmosphere; spectral bands with 1,000, 500, and 250 m resolutions; spectral bands that are adjustable to range from 0.4 to 14.4 µm with minimal out-of-band response; optomechanical apparatus; mainframe Long-lasting, continuously spinning double-sided scan mirror assembly; passive radiator; and superior sensitivity provided by advanced focal plane assembly (FPA) technology Space-Viewing Door, Solar-Viewing Door, Forward-Viewing Analog Module, Main Electronics Module (MEM), Earth-Viewing Door, Electronics System, Optical Bench Assembly, Optical System Description, Door Assemblies, and On-Board Calibration System Low ghosting and low scatter optics; on-board solar diffuser and solar diffuser stability monitor (SDSM); on-board full-aperture Blackbody (BB); IR calibration for low 1/f noise and good accuracy on each scan, Spectroradiometric Calibration Assembly (SRCA) mounted on-board.
