Abstract

Beach is an area that is physically subject to change. This change is caused by natural processes and human activities. Physical changes that generally occur on the beach are erosion and sedimentation. The dynamic processes that occur atthe beach are the result of a combination of various forces at work on the beach, which include the force of waves,currents, sedimentary movements, wind and so on. To analyze sediment transport in coastal areas, one of the main thingsthat need to be known is the characteristics of coastal sediments. The study was carried out on beaches prone to erosion and sedimentation, the location of sample data research at several points taken in the area around the Aeng TakalarVillage Beach and Padongko Barru Beach. The analysis carried out is the analysis of the distribution of sediment grainsto determine the characteristics of existing sediments on the beach. The results showed that the sizes of the sediment samples on the beach in Aeng Village, Takalar District were a mixture of fine sand and medium sand which had a diameterof 0.125 mm - 0.5 mm and the size of the sediment grains on the Padongko beach. Kabru was a mixture of fine sand and medium sand which has a diameter of 0.125 - 0.5 mm.

Abstract

Indonesia as a country which has a very large area and a high population as well as diverse geographical conditions and a dispersed population, still faces challenges in meeting energy for all its inhabitants. Many Indonesians do not have access to fuel and use traditional stoves for cooking. In fact, as we all know, Indonesia has a high potential for clean and renewable energy. The potential of these renewable energy resources can be utilized to create equitable and clean energy access. By looking at the achievement of using clean and renewable energy in Indonesia which is still low while the potential for renewable energy is quite high and widespread, the idea arises to take advantage of local potentials by creating a design of a biomass gasification tool that can be used in areas that do not yet have access to energy. Using simple tools that are easily obtained locally, the researchers designed a biomass gasification device, which will later be tested whether it is capable of producing gas fuel. This research has succeeded in proving that the gasification equipment that is assembled and uses rice husk and beach sand as fuel is able to produce gas for a fire which can later be used by the community, especially in coastal areas.

Abstract

El Nino–Southern Oscillation (ENSO) is a symptom of deviation in the surface temperature of the Pacific Ocean on the west coast of Ecuador and Peru which is higher than the normal average which is characterized by an increase in sea surface temperature in the Central and Eastern equatorial regions. ENSO climate variability consists of three phenomena, namely normal events, El Nino and La Nina. The development of the El-Nino Southern Oscillation (ENSO) event demonstrates an important role for the Madden-Julian Oscillation (MJO). This phenomenon is suspected to have a relationship and is closely related to the decrease and increase in the intensity of rainfall in Indonesia. This study was conducted with the aim of analyzing the relationship between the ENSO and MJO phenomena and their impacts in Aceh Province, through empirical methods with statistical calculations, based on ENSO variables in the form of the Nino 3.4 index, amplitude variables representing the MJO and rainfall data in Aceh Province. The data for these two variables were obtained from NOAA and BoM, while the rainfall data was obtained from NASA. The data period analyzed is 10 years, from 2010 to 2019. The two data will be filtered and analyzed for correlation using a simple linear regression method. From this study it was found that basically ENSO does have a relationship with the MJO and has a relationship with increasing and decreasing rainfall intensity in Aceh Province. However, the correlation is at a weak to moderate level, and the impact is not as strong in the Central and Eastern regions of Indonesia. This strengthens the hypothesis of the weak influence of ENSO in Aceh Province; where the strengthening of the MJO is more about its synergy with the IOD or Indian Ocean Dipole, especially on the positive value (P-IOD).

Abstract

area of ​​Makassar City is one of the areas experiencing significant land use changes. In addition, the pattern of changes in coastline from year to year that occurs in the coastal area of ​​Makassar City always experiences additions and decreases in coastal areas. This is due to the phenomena of accretion and abrasion and the sedimentation rate of the Tallo River formed in this area is quite large and continues to increase. The area directly affected and studied is Tamalanrea                      Sub-District. This study aims to analyze shoreline changes and their impact on land use over a period of 20 years in Tamalanrea Sub-District, using Landsat satellite imagery data. This research is expected to provide benefits to local governments as a basis for consideration in determining regional spatial planning policies, especially in the use of coastal land. The research method includes field observations, processing of oceanographic supporting data, digitizing and overlaying image data. Changes in the coastline for a period of 20 years (1998-2018) in Tamalanrea Sub-District were 20.14 Ha where the coastline that experienced accretion and abrasion was 12.20 Ha and 7.95 Ha, respectively. Changes in land use on the coast of Tamalanrea Sub-District for 18 years (2000-2018) which increased were residential land by 2.34 Ha, industrial/warehousing land by 82.37 Ha, public facilities land by 13.36 Ha, and mangrove land of 3.27 Ha. While the reduced land use is 70.89 Ha of wet land and 20.36 Ha of dry land. Changes in coastline to changes in land use in coastal areas in Tamalanrea Sub-District have physical, ecological/environmental, socio-economic, and institutional/legal impacts that are positive for the sustainable management of the coastal area of ​​Tamalanrea Sub-District.  It
