Abstract

Sea urchin is echinoderm that body surface is covered with the spines. Sea urchin gonad has been consumed along time by the people at Wakatobi Archipelago. Sea urhin species is worried will be degraded. On the other hand, there is no study on species composition, density, size and maturity stage of sea urchins on Tolandono Island and Sawa Island, Wakatobi Regency. The purpose of this study was to determine the species composition, abundance, size and maturity level of sea urchin gonads. Sea urchin density was calculated with a 10 × 10 m transect quadrate. The data was analyzed by descriptive qualitatively. The results showed that in Tolandono Island and Sawa Island there were 4 types of sea urchins, namely Tripneustes gratila, Echinotrix calamaris, Diadema setosum and Echinoemetra sp. The size of urchin Tripneustes gratilla is ranging between 2.5 cm and 8.5 cm with the density 2 Ind./100 m2. Meanwhile, the gonad maturation stage (TKG) of Tripneustes gratila is at a 4.8 cm and spawned at a size 8–8.5 cm. TKG I is in the size range of 4.8–5 cm, TKG II is at 5.9–6.2 cm, TKG III is 6.4–6.6 cm, TKG IV is 6.8–7.5 cm and TKG IV is 6.8–7.5 cm. V in size 8.5 cm.

Abstract

Sea urchin is an abundant fisheries resources in Pisou Village, Pagimana District, Central Sulawesi. This abundance is caused by the high productivity of sea urchins and the lack of utilization by the local community. The high density of sea urchins causes the poor quality of gonad and taste. This is mainly caused by the insufficient availability of food in the nature that can be only improved by aquaculture. This community empowerment was conducted in the Pisou Village for 5 weeks from February-March 2020. The aim of this program is to cultivate sea urchins in improving the quality of sea urchin gonad by aquaculture. Another goal is to educate the local fishers on how to culture and utilized the gonad a seafood and crackers. The result of this activity is the availability of floating net cages at Desa Pisou Village that can be used for sea urchin cultivation.

Abstract

Yellowstripe scad (Selaroides leptopleptis) is an economically important fish species from small pelagic fishery resources in TPI, Tenda Village, Hulonthalangi Subdistrict, Gorontalo City. Gonad Maturity (TKG), Gonad Maturity Index (IKG), and condition factors of yellowstripe scad. The results of the research yellowstripe scad (Selaroides leptolepis) between males and females have a gonadal maturity index (IKG) of 0.013%–0.025%, with the number of gonadal maturity levels (TKG) I is 24, TKG II is 22, TKG III is 10 tail, TKG IV is 1 individual and TKG V is 5 individuals. The value of relationship value between length and weight of yellowstripe scad (Selaroides leptolepis) is W=0,3945L1,0487 with a value of b<3 (negative allometric). The relative condition factors varied from 0.9051–1.069. Meanwhile, the fecundity of yellowstripe scad (Selaroides leptolepis) ranged from 23.760-78.000 eggs.

Abstract

Suritech (sea urchin technology) is a technology machine for threshing sea urchin spines for the production of sea urchin egg kukure. Sea urchins are echinoderms whose entire body surface is covered with venomous spines. The purpose of this study was to determine the speed, capacity and production of sea urchin eggs based on the Suritech machine. The purpose of this research is to provide information on how to manufacture suritech machines in managing sea urchins. The Suritech machine is capable of producing 100 sea urchins per 4 minutes or 36.000 urchin per day. The production of sea urchin eggs by the Suritech machine is able to beat the production of sea urchin eggs in Japan, which is only around 27.000 tons per day. Thus, the use of the Suritech machine as a thresher of sea urchin spines is expected to increase fishermen's income and position South Sulawesi as the center of sea urchin egg production in Indonesia.

Abstract

This Mendeley training aims to provide skills to participants regarding reference management and APA style citation techniques using Mendeley software, as well as how to submit articles in OJS-based journals. The method used in this training is Participant Active Learning which is followed by 42 participants. Some of the things that resulted from this training activity were 1) Participants were very enthusiastic about listening to the presentation of material related to an overview of Mendeley, how to do reference management using Mendeley software; 2) Participants were very enthusiastic in participating in the explanation of material related to APA style citation techniques using Mendeley software; 3) Participants actively participate in technical guidance and hands-on practice on how to perform reference management and APA style citation techniques using Mendeley; 4) Participants enthusiastically listen to the presentation of the material and the simulation submits articles to OJS-based journals. The conclusion of this training activity is that the activity went very well and smoothly even though there was a slight problem with the internet network, but it could still be overcome.

Abstract

The purpose of this study was to find out the abundance of sea urchins in the waters of South Leato Beach. The study was conducted in the waters of Blue Marlin Beach and South Leato Beach, Dumbo Raya Subdistrict, Gorontalo City in November 2021 with two sampling stations. Data retrieval is done using direct observation methods at two stations. Data collection is done by installing a transect of 1×1 meter with the transect distance of each point is 10 meters starting from the edge of the island's waters towards the sea. After that, data is carried out in the form of observations of sea urchin types and counting the number of individuals of each type of sea urchin in the transect. The data collection in this study was conducted in just 1 day. The type of sea urchin found on leato beach is 3 types, namely, Echinothrix Calamaris (white thorns), Dianema Setosum (black thorns) and Echinothrix Calamaris (striped brown thorns). Types of sea urchins found on the blue marlin beach are 3 types, Tripneustes gratilla (collector's sea urchin), Burrowing urchin (porcupine that digs) and Diadema savignyi (Long sea urchin).

Abstract

Blue Marlin Beach has been functioned as the marine tourism attraction by the local government of Gorontalo regent due to the beauty of the underwater. However the natural resources in the Blue Marli Beach have not been docuented, specifically for macroalgae. Therefore, this research aims to provide the data and information about species composition of the green macroalgae in the Blue Marlin Becah. This research was conducted for two months starting from November to December 2020. The measurement of GPS coordinate, seawater current, temperature, and wave actiion was concucted with Fishing Points Software. Observatory methode was performed in this study to collect the specimens. Then, all specimens was put-in the zipperbag and stored in the coolbox containing with the ice to protect the specimens in fresh. The results show that there are 6 species of the green macroalgae. Theya are Bornetella sphaerica, Caulerpa sertularioides, Valonia aegagropila, Boergesenia forbesii, Acetabularia caliculus, and Chaetomorpha crassa. The average of sea water temperatur during the study is 31°C with the seawater current is 0.1 m/s and wave is 0.2 m
