Abstract

"Krosok" salt, or "Crude Solar Salt", is salt produced through the evaporation and crystallization of seawater. Some krosok salts have different qualities, and this is influenced by the quality of seawater as raw material, available production facilities and post-harvest handling. This krosok salt is mainly produced by salt farmers along the north coast of Karawang Regency. This study aimed to determine the quality of krosok salt obtained from salt farmers in Karawang Regency and to raise salt quality standards to increase the sale value of salt by creating healthy and industrial salt products. The method is to re-crystallize the "krosok" salt by adding binders or additives. Based on the results of the salt crystal test in the laboratory, it is known that the crystallization of "krosok" salt in Karawang Regency has a NaCl content of up to 99.35%; this value is already above the SNI quality standard of 98% as health salt. Meanwhile, for hazardous materials such as (Hg) and (As), the content is around 0.001%, below the SNI threshold of 0.1%.

Abstract

The beach has an important role in the development and economy of a region. Therefore, it is important to understand the condition and characteristics of the coast so that it can be managed and developed wisely. One way to understand the condition of the beach is through making a map of the characteristics of the beach. A coastal characteristic map is a graphical representation of the conditions and characteristics of the geology, geography, and hydrology of a coast. Making a coastal characteristic map with remote sensing requires several steps, namely: 1). satellite data collection: Pre-processing satellite data; 2). classification of satellite data; 3). satellite data analysis; and finally 4). making a coastal characteristic map. The area that is the fabric material is the beach of Indramayu Regency, West Java. Based on the analysis and interpretation of 2015 Landsat 8 (LDCM) image data, 2020 Sentinel 2 Image data, BATNAS, and DEMNAS data, it is known that the characteristics of the Indramayu beach are that it has geo-quaternary building materials which include: (a) coastal bunds, ( b) swamp deposits, (c) shallow marine deposits, (d) sand deposits, (e) flood plains, (f) river deposits, and (g) floodplain deposits. The morphology includes: (a) beach sand plains, (b) concave coastal swamps, (c) old beach bunds, (d) young beach bunds, (e) alluvial plains, (f) flood plains, and (g) fan plains delta. Finally, it has a distribution of surface sediments on the seabed which includes: (a) sand, (b) silt, gravelly sand, (d) slightly gravelly silt, (e) slightly gravelly sandy mud, and (f) gravelly mud.

Abstract

Water is one of the basic needs for human life, including for people living on the coast. It is difficult to get clean water for consumption because most coastal areas are affected by sea conditions that have high salinity. In order to be consumed, the saline water must be desalinated. Desalination is a process to convert saline water into fresh water. One such desalination technology is using reverse osmosis (RO). The purpose of this study was to determine the process of desalination of seawater into freshwater using the seawater reverse osmosis (SWRO) method. The method used in this research is observation, which is to see directly the stages of the desalination process of seawater into fresh water. The data was obtained in the form of primary data from observations and secondary data from the literature to support primary data. Analysis of the data used in the form of descriptive analysis by describing each stage carried out in the SWRO process. The results showed that the seawater desalination process using SWRO technology had 14 stages. These stages include; intake, raw water pump, raw water reservoir, UF feed pump, Automatic screen, ultrafiltration, UF water reservoir, RO feed pump, HPP & booster, RO membrane, RO water reservoir, permeate pump, chlorine analyzer, product water. In developed and developing countries, SWRO units have been widely used, because by processing seawater into freshwater, there are many benefits for the life cycle and it is environmentally friendly. It also maintains underground fresh water so that it can provide plant life, and trees that provide us with clean oxygen for our lives.

Abstract

Discus is one of the ornamental fish that lives in freshwater. Discus is a fish that is quite famous among ornamental fish lovers. Discus (Symphysodon discus) belongs to the Cichlidae family which comes from the calm waters of the Amazon river. This fish is also known as the King of Aquarium. Its body shape is round like a disc and its movements are smooth. Discus enthusiasts are numerous, and they are also creative to bring up new varieties that are better and more attractive, which are in demand by the public. All strains of discus fish are in demand by both local and export communities. At Mischosella Fish Cipayung Farm, 3 types of discus are cultivated, namely Pigeon, Turquois, and Malboro. These three types of discus have distinctive patterns and colors. The productivity of these three types of discus greatly influences the company's productivity in producing discus seeds. The purpose of this study was to determine the productivity of the Pigeon, Turquois, and Malboro discus at the Mischosella Fish Cipayung Farm and at the same time provide suggestions for the types of discus broodstock that need to be developed. The parameters observed in this study were brood spawning frequency, fecundity, hatching rate, and survival rate of discus larvae. Based on the results of the study, the spawning frequency was carried out by the Turquise species (9 times during the observation) while producing the most eggs (217 eggs). However, the highest hatching rate was produced by the Marlboro discus parent (96.26%). However, the highest survival rate was found in discus larvae produced by Turquise breeders (84.4%), and the highest ABL values were found in Marlboro and Pigeon. Water quality during larval rearing in the media for raising discus larvae for Pigeon, Turquise, and Marlboro types is in the same range, namely temperature 26 – 30.5oC, pH 6 – 6.8 and DO 5.5 – 6.3 mg/l. the optimum range for breeding discus seeds.

Abstract

According to the suitability of water conditions for tiger grouper aquaculture, there are several water quality factors such as temperature, pH, salinity, water depth, current speed, water brightness, and dissolved oxygen. The purpose of this study was to analyze the value of the physical-chemical parameters of the waters and the suitability of the water conditions for the cultivation of tiger grouper (Epinephelus fuscoguttatus) in the Nasik Strait waters. This research was conducted in February 2021 with water quality analysis carried out in situ and ex-situ (Environmental Services Laboratory) at 4 different stations.  The method used in this research is descriptive qualitative and the purposive sampling method is used to determine the location of the station.  Observation of water conditions using physical and chemical parameters consisting of temperature, pH, salinity, water depth, current speed, water brightness, and dissolved oxygen and carried out using matching methods for data analysis.  The results of this study indicate that the waters of the Nasik Strait have a sufficient level of suitability for tiger grouper aquaculture according to the results, namely;  Station 1 with a suitability value of 87%, which is put in the Very Suitable class (1), Station 2 with a suitability value of 87%, which is put in the Very Suitable class (1), Station 3 with a suitability value of 80% which is put in the class  Sufficiently Appropriate (S2), and at Station 4 having a suitability value of 80% is put in the Sufficiently Appropriate (S2) class.  The results show that the waters of the Nasik Strait are in the category of Very Suitable and Fairly Suitable for the development of tiger grouper aquaculture and indicate that the waters of the Nasik Strait are suitable as cultivation locations and need to be maintained regarding water quality by managing water quality management.
