Opis:
Indonesia is an archipelago with a coastline of about 81,000 km and has enormous cultivation potential. The area that's the potential for aquaculture is estimated at 15.59 million hectares, consisting of 2.23 million hectares of freshwater cultivation land, 1.22 million hectares of cultivated land in brackish waters, and 12.14 million hectares of marine areas. Nowadays, only 10.1% freshwater, 40% of brackish water, and 0.01% of the marine area potentially suitable for cultivation are being used. However, land use for shrimp farming until 2017 has only reached 20% of the total potential. It is still very open to developing land for the extensification of shrimp farming. Shrimp is one of the non-oil and gas export commodities that play a crucial role. Besides the high price, shrimp also has a large market in various countries. Although the industry suffered disease outbreaks and environmental problems, Vannamei shrimp farming has recently seen a rapid expansion in Indonesia due to superior varieties and disease resistant shrimp. Vannamei shrimp is a new variety that’s some advantages, including more resistance or resistance to disease and low environmental quality, high stocking density, shorter rearing time, which is around 90-100 days per cycle. This study provides some necessary background for Vannamei shrimp farming in Indonesia. It focuses on the operating characteristics of shrimp farming in brief. Emphasis is placed on the impact of shrimp farming on the environment. Promising strategies for reducing nutrient release from shrimp farming are analyzed. Effective management measures to resolve or mitigate the adverse environmental effect of shrimp farming development have now become necessary and urgent. The sustainability of shrimp farming depends on many factors including the completeness of policies and regulations, good ecology, superior breeding and various kinds of cultivation technology and government support, advances in technology digitization and cooperation between industries shrimp farming.

Opis:
One of the complexities of the ocean currents in the territorial waters of Indonesia is oceanic eddies form. Ocean eddy is one of the very crucial phenomena in the ocean due to its circulation and connection with the chemical and biological aspects in the water column. This study aimed to observe the distribution of oceanic eddies associated with the Sea Surface Temperature (SST) and Sea Surface Height (SSH) with the Automatic Eddy Detection (AED) method. The analysis included distribution and types correlated with seasons. The results showed that eddies occur in all regions in the Indonesian Seas except the Java Sea. In general, the occurrence of eddies every month does not differ significantly for both Ocean Cyclonic Eddies (OCE) and Ocean Anticyclonic Eddies (OAE). The total oceanic eddies in a year are around 1,149 events. A minimum radius of the ocean eddies found was about 5.08 km, and a maximum was around 386.76 km. Furthermore, the occurrence of OCE is mostly in locations that are almost the same as OAE. Both types of eddy are mostly in locations with the boundary of temperatures and the boundary of SSH. Several eddies exist every month and mostly change or move into other areas. Eddies in Indonesia seas are influenced by differences of SST and different SSH that form ocean currents.

Opis:
COVID-19 is a disease emerged from China in the late 2019 and still spreading to this date. Scientists worldwide are trying to give their contributions in many aspects, from searching for the vaccine to studying several policies in many aspects to deal with this disease. One of the important researches in COVID-19 is to study and predict the dynamic of the spreading by using epidemiological model. This research has been taken in many countries independently since the behavior of COVID-19 spreading might differ from one another. Each country has their own characteristics-e.g., the population density, geographic condition, health facilities and infrastructure, weather condition-which caused the different patterns of COVID-19 spreading. Therefore, each country probably has their own unique parameters which describe their own dynamicity of COVID-19 spreading even though the epidemiological models used in different countries are the same. Thus, in this paper, we estimate the parameters involved in our SIR epidemiological model for cases in Indonesia by using Least Square Method in Python. We use the daily cases released from Indonesian COVID-19 Response Acceleration Task Force. Several assumptions are made in this model, including the assumption that there is no vaccination to be released yet. The result shows that the COVID-19 will still exists in Indonesia for over 1.9 years from the first case emerged (until mid January 2022).

Opis:
Coconut oil is a source of fat which still sparks controversies when it comes to function. Some stated it can worsen lipid profile which then play an important role as a risk factor of cardiovascular disease. This cross sectional study was conducted in Indonesia involving 57 participants who used coconut oil as a predominant source of fat. Body mass index, physical activity and dietary intake were considered as subject characteristics. Serum concentrations of total cholesterol, triglyceride, LDL-c, HDL-c were determined by using the enzymatic method and Apo A1 were determined by using immunoturbidometry method. Result implied normal range of lipid profile and 78.95% of the subjects have optimal LDL-c/HDL-c ratio. Majority of the subjects (61.4%) have acceptable level of Apo A1, it showed that they have good HDL-c level. These results are consistent with other studies that support beneficial effect of coconut oil on lipid profile.
