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

Salinity is the level of saltiness or salt content dissolved in water. Salinity is the total concentration of dissolved ions in water. The amount of salinity greatly affects the growth and survival rate of biota in the waters. To find out the salinity can be done by direct measurements in the field or by modeling. The purpose of this study was to determine the value of the salinity parameter by modeling salinity using the MIKE-21 Software at the mouth of the Citanduy River, Pangandaran Waters. MIKE-21 software is a hydrodynamic modeling software used to predict marine physics parameters, one of which is the value of the salinity parameter. The results of salinity modeling carried out at 4 observation stations at the mouth of the Citanduy River obtained an average value of salinity at high tide at the mouth of the river was 17.05 ppt and at low tide was 14.31 ppt.

Abstract

Tides are the rise and fall of sea level caused by the attraction of objects in the sky, especially the moon and sun, to the mass of seawater on earth. Tidal research is useful for providing information about the components and types of tides and predicting tides and for mitigating natural disasters. Tidal measurements were carried out in the Nasik Strait, Bangka Belitung using the Valeport 106 tool. Tidal data was processed using the Admiralty Method. The Admiralty method is a method used to calculate tidal harmonic constants from observations of water levels. With this method, it is possible to know the amplitude and phase difference of the tides, the value of the Formzahl number, and the type of tide. From the results of data processing and analysis, the value of the Formzahl number in the waters of the Nasik Strait is 11,454 and the tidal type is a single daily tidal type that only occurs at one high tide and one low tide in one day.Keywords: tides; tidal types; admiralty method; formzahl numberAbstrakPasang surut adalah naik turunnya muka air laut yang disebabkan oleh gaya tarik benda-benda di langit, terutama bulan dan matahari terhadap massa air laut yang ada di bumi.

Abstract

A sensor called an ultrasonic sensor works by converting electrical quantities into physical quantities (sound) and vice versa. An Arduino Uno is required to activate the system's ultrasonic sensor. The reservoir's water level is determined using ultrasonic sensors. The purpose of this investigation is to learn how to put together, program, and utilize the HC-SR04 Arduino Uno ultrasonic sensor with the Arduino IDE (Integrated Development Environment) application. Controlling the water in the desalination system is required so that the water entering the reservoir does not waste or overflow and pollute the desalinated water. An ultrasonic sensor is attached to a seawater desalination system using the evaporation method, and the sensor is put on the edge of the evaporation pond in order to conduct experimental testing of the ultrasonic sensor on the device. The desalination tool can operate more efficiently and under control with the help of the HC-SR04 ultrasonic sensor by automatically filling the water in the evaporation pond. The sensor will automatically supply the water shortage when the seawater evaporates. Results of experimental observations made with the HC-SR04 ultrasonic sensor on an evaporation bath with three water filling cycles are available. so that after 7 days, 13% of the volume that was filled in the evaporation basin has evaporated.

Abstract

Kawasan pesisir sering menghadapi tantangan lingkungan yang kompleks, seperti abrasi, deforestasi, pencemaran, dan kegiatan ilegal yang merusak ekosistem laut. Sayangnya, mayoritas masyarakat pesisir sebagai aktor kunci kegiatan monitoring masih terbatas dalam mempelajari dan mengaplikasikan teknologi yang relevan. Sehingga laju upaya konservasi dan rehabilitasi pesisir tidak bisa mengimbangi laju kerusakan yang terjadi. Oleh karena itu, penting untuk mengembangkan sistem pemantauan yang efektif untuk menjaga keberlanjutan ekosistem pesisir. Sistem pemantauan ini dikembangkan untuk meningkatkan keterampilan masyarakat dalam memanfaatkan aplikasi dan wahana pemetaan sebagai alat monitoring, untuk meningkatkan efektivitas konservasi dan rehabilitasi pesisir. Metode yang digunakan adalah pendekatan partisipatif, yang memungkinkan masyarakat berkolaborasi dengan perguruan tinggi dalam melakukan monitoring berbasis aplikasi dan wahana pemetaan, khususnya dalam pemanfaatan drone. Peserta kegiatan adalah enam kelompok masyarakat konservasi (POKMASI) yang berada di pesisir Kabupaten Karawang. Evaluasi kegiatan dilaksanakan melalui observasi lapangan, FGD, serta analisis terhadap data spasial yang dihasilkan POKMAS. Hasil yang signifikan dari kegiatan ini adalah meningkatnya partisipasi masyarakat dalam pemantauan kawasan pesisir, pengayaan metode pengawasan, terbentuknya jejaring komunikasi yang efisien, serta aksi kolektif untuk menjaga kawasan konservasi dan rehabilitasi pesisir Kabupaten Karawang.

Abstract

The existence of the coast in the northern part of Karawang Regency is very worrying. Seawater that was far up to tens of meters from the side of the road, is now on the lip of the road, even some parts of the road are cut off due to abrasion of seawater. Some villages were affected by abrasion erosion. One of the effects of damage due to abrasion and sedimentation is the occurrence of shoreline changes. This change in coastline will affect people's lives and spatial planning for the development of the area. For this reason, this study aims to determine the extent and rate of shoreline changes that occurred on the coast of Karawang Regency in the periods of 1989, 1995, 2001, 2005, 2009, 2016, and 2018. The shoreline data was obtained from the extraction of Landsat 3 MSS, Landsat 5 TM, Landsat 7 ETM +, and Landsat 8 OLI-TIRS after the NDWI process was previously carried out. While the rate of change is calculated at 6 sample point locations scattered along the northern coast of Karawang Regency. The results showed that the largest area damaged by abrasion occurred in Sedari Village covering an area of 166.802 hectares, and the area formed by the largest sedimentation occurred in Muara Cilamaya Village at 276,318 hectares. Meanwhile, the fastest rate of shoreline change due to abrasion occurred in Sukajaya Village at 10 meters /year, while the slowest in Sedari Village at 3.77 meters / year. The fastest sedimentation process in Muara Cimalaya Village is 4.5 meters / year, while the late one in Tanjung Pakis Village is 3.09 meters / year.
