“…In the cultivation of K. alavarezii the substrate plays a role in maintaining sediment stability which includes protection from water currents and a place to get nutrients (Dahuri, 2003;Edward, 2003;Bengen, 2001). in waters will affect the density and growth of K. alavarezii (Ain et al, 2014). So that the substrate is one of the important components that play a role in the growth of seaweed (Indrawati et al, 2009).…”

The planting method greatly affects the growth and carrageenan content of Kappaphycus alvarezii seaweed. In addition, the planting method will also affect the physico-chemical conditions of the waters which are closely related to the growth of K. alvarezii. This study aims to determine the appropriate method of seaweed cultivation so that it can be used as a reference for K. alvarezii farmers to pay more attention to appropriate and appropriate cultivation methods in cultivating K. alvarezii so as to improve the quality of seaweed. This study begins with observations at the sampling location, taking water samples and samples of K. alvarezii seaweed. The research data was processed using SPSS (Statistical Product and Service Solution) version 16.0 software with analysis of variance (One Way ANOVA) to obtain parameters that affect the quality of seaweed so that the appropriate planting method can be determined. The results obtained from this study, the appropriate method for planting K. alvarezii in Palasa using a floating raft, in Lobuk and Padike using the bottom method, while in Tonduk using the long line method.

“…Rhodophyta banyak ditemukan di kawasan dengan substrat dasar yang dominan berlumpur dan juga ditemukan berasosiasi dengan ekosistem lamun. Chlorophyta ditemukan pada habitat dasar dengan tipe substrat yang didominasi oleh pasir, karang hidup, dan batu karang sedangkan Phaeophyta lebih banyak ditemukan di daerah dengan substrat dasar yang didominasi oleh pecahan karang (Yudasmara, 2011) Ain et al (2014 menyatakan bahwa suatu lingkungan perairan dalam kondisi stabil akan menunjukkan jumlah individu yang seimbang dari semua spesies yang ada, sebaliknya jika suatu lingkungan perairan berubah-ubah akan menyebabkan persebaran spesies yang rendah dan cenderung ada individu yang dominan. Keragaman jenis rumput laut ditentukan oleh substrat pada dasar perairan di daerah pasang surut.…”

Hydrocolloid seaweed is a seaweed which contains agar, carrageenan and alginate, which are widely used as industrial raw materials. This study aims to determine the type composition of hydrocolloid seaweed and its density based on the characteristics of the bottom waters in the intertidal area of East Nusakambangan Cilacap. The waters of East Nusakambangan have a central coral beach and a hollow coral beach which has a substrate in the form of sand, coral, volcanic rock, and coral fragments. This study used a survey method and sampling using a transect, a perpendicular line of the coast towards the sea, each transect line was placed with a quadrant plot (1 x 1m 2 ) randomly selected on hard and soft substrates. The results of this study, the coral substrate on the two beaches obtained 2-8 types of hydrocolloid seaweed, with the highest composition of seaweed species of 57.6% on hard substrate with the highest density in the Gracilaria gigas species; 440.6-1239.7 g/m 2 , Gracilaria gigas has a dichotomus branching type with a cylindrical talus shape. In the mixed substrate on the coast of Karang Tengah, there were 4 types of hydrocolloid seaweed with a composition of 46.3% hydrocolloid species with the highest density in the species Padina australis; 387.7 g/m 2 . Padina australis sheet and unbranched talus form

“…Pantai Bandengan adalah salah satu pantai pesisir utara Jawa yang terletak di Kabupaten Jepara, Jawa Tengah. Kabupaten Jepara memiliki potensi sumberdaya pesisir yang besar ditinjau dari keberadaan garis pantainya lebih dari 72 Km (Ain et al, 2014). Pantai Bandengan merupakan daerah teluk berpasir putih dan halus dan memiliki ombak yang tidak terlalu besar sehingga dijadikan sebagai kawasan wisata potensial di Jepara dan diminati oleh berbagai kalangan.…”

Pantai Bandengan merupakan salah satu pantai wisata di Kabupaten Jepara dimana terjadi aktifitas pembangunan yang cukup massif sejak beberapa tahun terakhir yang bertujuan untuk menunjang kegiatan rekreasi wisatawan. Namun terdapat ancaman dalam pengembangan sektor wisata tersebut berupa perubahan garis pantai yang disebabkan oleh sedimentasi dan abrasi yang dapat mengganggu perekonomian masyarakat yang memiliki mata pencaharian di wilayah tersebut. Tujuan penelitian ini yakni untuk mengetahui dampak sedimentasi dan abrasi terhadap luas daratan serta mengidentifikasi wilayah-wilayah yang rawan terhadap perubahan garis pantai. Metode yang digunakan yaitu interpretasi citra satelit Google Earth Pro serta survei lapangan menggunakan alat Sediment trap dan bola duga. Pengolahan data citra diproses menggunakan software ArcGIS 10.2 untuk mendapatkan luasan wilayah sedimentasi serta abrasi. Sediment trap digunakan untuk mendapatkan laju sedimentasi dan karakteristik sedimen. Berdasarkan hasil penelitian, dalam lima tahun terakhir sejak 2015 hingga 2019 terjadi sedimentasi seluas ± 8062,9 m2, sedangkan abrasi seluas ± 12.502,1 m2. Sedimen penyusun perairan didominasi oleh lanau pasiran serta kecepatan arus permukaan berkisar 0,085 m/s hingga 0,197 m/s. Bandengan beach is one of the tourist beaches in Jepara Regency where there have been massive development activities since the last few years aimed at supporting tourist recreational activities. However, there is a threat in the development of the tourism sector in the form of changes in the coastline caused by sedimentation and abrasion that can disrupt the economy of people who have a livelihood in the region. The purpose of this research is to determine the impact of sedimentation and abrasion on land area and identify areas that are prone to shoreline changes. The method used is the interpretation of Google Earth Pro satellite imagery and field surveys using a Sediment trap and floating ball. Image data processing is processed using ArcGIS 10.2 software to get the area of sedimentation and abrasion. Sediment traps are used to obtain sedimentation rates and sediment characteristics. Based on the results of the study, in the last five years since 2015 until 2019 there is a sedimentation area of ± 8.062,9 m2, while abrasion area of ± 12.502,1 m2. The constituent sediments of the waters are dominated by the sandy silt and surface current velocity ranges from 0.085 m/s to 0.197 m/s.
