Abstract

Provision of seedlings A. muelleri in bulk can be done using seeds. The problem is seeds A.muelleri will be die if planted directly in the field. That caused seeds losing competition with weeds. So  needs a treatment to grow the seeds until zero generation (G0) tubers is formed. The technique used to maximize the formation of G0 tubers A. muelleri is selection of seed types and planting media. There are 3 types of seeds used, namely R  (red fruit seeds), Y (yellow fruit seeds) and G (green fruit seeds) where each type has a different level of maturity. Meanwhile there are 4 types of planting media used, namely M1 (soil: husk charcoal), M2 (soil: cocopeat), M3 (soil: cocopeat: husk charcoal) and M4 (soil). Every R, Y and G seeds were planted on M1, M2, M3 and M4 media. The parameters observed were weight, thickness and diameter of the G0 tubers. The data obtained were analyzed with 5% ANOVA and if there were differences followed by the 5% Tukey test. The results showed that the best G0 tubers were produced from planting R type seeds on M3 (RM3) media weighing 3.63 grams but were not significantly different from the treatment of planting R type seeds on media M1 (RM1) which was weighing 3.06 grams.

Abstract

Shark and ray fishery issues raised in Indonesia as some species have been listed in the IUCN red list. In relation to the conservation of some shark and ray species, critical information is required related to several biological aspects to assure its fishery sustainability. This study was conducted in Brondong Fishing Port in February – March 2020. Length, weight, and maturity level data were collected from 272 shark individuals and 267 ray individuals. Several analyses were performed, such as length-weight relationship analysis, sex ratios, and maturity level analysis. The study found 18 species listed in the IUCN red list were dominantly composed of Carcharias taurus and Dasyatis kuhlii. Both species have negative allometric, while the sex ratios showed that the ratio of the number of male and female individuals for shark and ray are 1:5 and 1:2, respectively. The maturity level of male individuals for Carcharias taurus pointed that 33% full calcification (FC), 17% non-full calcification (NFC), and 50% non-calcification (NC), while for Dasyatis kuhlii resulted that 66% FC, 28% NFC, and 6% NC. It is concluded that the biological aspects of the dominant species indicated that most individuals were in a critical state, thus it is required to monitor and control their fishing pressures.

Abstract

Indonesia is an archipelago country that is ranked top of the world for its breadth and wealth. More than 75,000 km2 or almost 14% of the world's coral is in Indonesia. The growth of coral reefs in a sea water is strongly influenced by the quality of waters such as chemical oceanographic factors, namely salinity, pH, DO, nitrate and phosphate. The data collection was carried out twice in September and November 2019 in Damas Waters, Trenggalek, East Java. The purpose of this study is to influence the quality of waters on the growth of coral reefs in Damas, Trenggalek, East Java. The sampling method is purposive random sampling that is the determination of the sample with certain considerations. The location points used by 20 stations are spread, namely on artificial reefs, natural coral reefs, open seas and the area around the harbor. Measurements made include in situ water quality with a multiparameter measurement tool, namely AAQ. The results showed the quality of waters in accordance with environmental quality standards with a value of (1) salinity 31.5 - 3.6 (2) pH 7.9 - 8.1 (3) DO> 5 mg / L (4) Nitrate 0.001-0.007 mg / l (5) Phosphate 0.012 - 0.345 mg / L. Correlation value of all components> 0.5 then the relationship of each parameter and coral reef affect each other.

Abstract

The aim of this research is to identify the surface structures of geothermal area in Kawi-Songgoriti based on lineament density and surface manifestation. The lineament density is processed by using satellite image as the input data. The surface structures were analyzed through the density of lineaments on the surface with FFD method. The lineaments are assumed associated with fractures or faults found in geothermal areas those are generally covered by surface manifestation which are hard to be identified. These faults and fractures were assumed as weak line that act as fluid thermal movement, thereby it can be used as guidance for the location of permeable area or a reservoir.  As a result, the high lineament density can be found in Kawi thus assumed as the control of Songgoriti manifestation.

Abstract

Currently the construction of reclamation in Jakarta Bay being carried out on several islands that have been approved by the Government of Indonesia and located nearby the Mangroves forests ecosystem which always inundated by seawater and are affected by tides.  The purpose of this study were analyzing the changes in the mangrove ecosystem area due to the changes in Total Suspended Solid (TSS) based sedimentation and the effect of hydro-oceanography factors on the TSS. This research was conducted using a literature study, processing the LANDSAT OLI images for the analysis of mangrove changes, TSS analysis, and analysis of the effect of hydro-oceanography on TSS within the years of 2013 to 2020. The results of this study indicate that the area of mangrove forest on the coast of North Jakarta is enlarging by 3-5 ha/year, especially in the reclamation island area due to the process of sedimentation which is influenced by hydrooceanography. High sedimentation can be shown from the high value of Total Suspended Solid (TSS) in the waters. The TSS values processed by the satellites images also showed a significant increase during these years between 2013 to 2020 except December 2018 experienced the lowest value. While the hydro-oceanographic factor has lesser effect on the TSS value compare to mangrove ecosystem in the study area.

Abstract

Miang Island is located at coordinates 118° 0' 20" E - 0° 44' 0" N which is administratively in Sangkulirang District, East Kutai Regency, East Kalimantan. Coral reefs on Miang Besar Island have an area of ± 218.8 ha, with the best coral cover in the waters of Sangkulirang District and one of the best in East Kutai Regency. Reef fish have an active role in coral reef ecosystems because they can be indicators of the health of coral reef ecosystems and can be used to measure the level of suitability of their habitats. If the condition of the coral is damaged, the number of reef fish that inhabit it will decrease because the habitat does not meet the availability of food ingredients and the loss of breeding grounds. Coral reef data retrieval using the UPT method and reef fish using the UVC method. The percentage of coral cover on Miang Island is in the moderate to bad category where the average percentage of cover is 21% which is in poor condition (<25%). The total abundance of fish at station 1 was 0.45 ind./m3, station 2 was 0.10 ind./m3, station 3 was 0.06 ind./m3, and station 4 was 0.09 ind./m3. The genus Acropora is the dominant coral genus at all stations and the Pomacentridae family is the dominant family of reef fish at all stations. The relationship between the percentage of coral cover and the abundance of reef fish is very strong with an R2 value of 72.13%.

Abstract

Coastal ecosystems are very vulnerable to environmental changes, and one of the variables of resilience in coastal areas is wave height. Clungup Beach is one of the beaches located in South Java with the characteristics of high waves. Analysis of wave height forecasting to minimize environmental damage in the future. The wave height forecasting method is carried out by two methods, namely Fisher Tippet-1 and Weibull, with the aim of comparing the results of forecasting the resulting waves and validating the forecast data. The source of wave data for 10 years (2009 - 2018) was obtained from the ECMWF (European Center for Medium-Range Weather Forecasts) website. The results of data analysis show that the wave height of Clungup Beach for a period of 10 years (2009 - 2018) with the highest value in July 2013, namely 2.67 m and the lowest in June 2010 with a value of 2.28 m, which is classified as a wave extreme in accordance with the Regulation of the Head of BMKG No. KEP. 009 of 2010. Wave forecasting with the Fisher Tippet-1 method return period in 2020 is 2.48 m and in the next 50 years (2069) is 2.76 m. Whereas in the Weibull method, the wave value for 2020 is 2.43 m and for the next 50 years (2069) is 3.01 m. The two methods used have the equation that the wave height that will occur in the Clungup Beach area will experience an increase (upward trend). This will be the basis for determining the scenario of coastal area protection, so that the resilience of coastal ecosystems will be well realized.

Abstract

The phenomenon of missing fishing gear during operation (Ghost fishing or Abandoned, lost or otherwise discarded fishing gear (ALDFG) becomes one of the serious problems in passive fishing gear. It's still a challenge and consensual for researchers to find the solution to solve this issue. This research is a steps of efforts to overcome it by using crab snares construction that has been used for recreational fishing activities. Crab snares consists of bait components and snaring rope. The research step consists of designing trap construction; selecting materials; building fishing gear; and conduct laboratory-scale trials. Then calculations of the effectiveness of the snare to catch crabs at various sizes. Observations during laboratory trials show that crab snares are capable of catching various sizes of crabs. Furthermore, the crabs caught were categorized into small, medium and large size groups based on their carapace width. analysis results of the effectiveness of catching snares show the highest value is 94.6% for catching large crabs, in the second position the effectiveness value is 86.4% for catching small crabs and the lowest is for catching medium crabs the effectiveness value still reaches 84.6%.

Abstract

Multispecies demersal fisheries management in Brondong waters have been managed by conventional single-species approach for determining catch quota or annual allowable biological catch (ABC). This might be impractical since a multispecies fishery should be managed by a multispecies fisheries management approach. The feedback harvest control rule (HCR) is a harvest control rule that has been validated and might be applied for a multispecies fishery. The aim of this study is to compare the conventional single-species approach and the feedback HCR in order to estimate the annual ABC. In this study, the annual ABC was calculated by applying two HCRs, the conventional single-species approach that applying the Schaefer surplus production model into the catch and effort of the dominant demersal fisheries data series of 2011 – 2020. The results showed that the Schaefer model provided the annual ABC higher than the feedback HCR estimation. Therefore, it was safe to apply the feedback HCR than the Schaefer model to determine the annual ABC. Under data-limited conditions, the feedback HCR might be an option to manage multispecies fisheries.
