Abstract

Urfu Bay is a relatively new marine tourism destination and quite a favorite among the people of Biak Numfor. The Tourism Awareness Group (POKDARWIS) of Urfu Village is developing mangrove tourism. At the same time, scientific data is not yet available on the area's suitability level and the environment's carrying capacity for mangrove tourism activities. Hence, this research must be carried out to support the sustainable management of Urfu Bay mangrove tourism. The objectives of this study are: (1) knowing the tourism suitability index (IKW); and (2) knowing the carrying capacity of the Urfu Bay mangrove ecosystem (DDK). The study time is six months, which is April to September 2023. This research is located in the mangrove ecosystem of Urfu Bay, Biak Numfor Regency. The research method used is a survey, while random sampling techniques, observation, interviews, and literature studies carry out data collection. The results showed that the mangrove ecosystem of Urfu Bay: (1) Very suitable as a mangrove tourism area with a tourism suitability index (IKW) value of 2.85; and (2) Has an Area Carrying Capacity (DDK) of 381 people per day. This study concludes that the mangrove ecosystem of Urfu Bay is very suitable and prospective for developing mangrove tourism.

Abstract

Local people on Numfor Island are very dependent on coastal and marine natural resources around it, including making seagrass ecosystems as an area to find and capture various marine life to meet their daily needs. Intensive fishing activities cause stress on seagrass ecosystem biota, one of which is Siganus spp. It is known, that some Siganus fish live and breed in seagrass ecosystems, so the existence of habitat and the continuity of their life cycle needs to be studied for scientific data on Numfor Island. The objectives of this study are: (1) analysing seagrass biodiversity, and (2) identifying spawning ground Siganus spp. The research method used is a survey, while data collection is through square line transect techniques, in situ measurements, and interviews (questionnaires). The results of the study obtained are: [1] Seagrass dominance index is low; [2] The Shannon-Wiener Index (H') is moderate at Kansai, Kornasoren, and Andei stations, while at Bawei, Mandori, and Wansra stations are low; [3] Seagrass evenness index is classified as the community in stable condition at Kansai and Bawei stations, while at Kornasoren, Andei, Mandori, and Wansra stations classified as community in unstable condition; and [4] The identified spawning ground locations of Siganus spp. fish on Numfor Island are Kansai, Bawei, Mandori, and Wansra stations. This study concludes that there are no dominant seagrass species and stable ecosystems, medium and low diversity with moderate and severe ecological (environmental) pressures, and seagrass uniformity in stable and unstable conditions

Abstract

Nitrate (NO3-) and phosphate (PO4^3-) are two compounds that have a significant impact on aquatic ecosystems. Nitrate, which consists of nitrogen and oxygen, has both natural and anthropogenic sources. Meanwhile, phosphate, which contains phosphorus and oxygen, is an important component in plant nutrition. This is a problem in the Bodri River Estuary, Kendal. The objective of this study was to assess the nitrate and phosphate content and their distribution pattern. The research was conducted based on observation method with spatio-temporal approach. A total of 9 research stations and sampling times were June 30, September 1 and October 27, 2018. Nitrate and phosphate content were determined as independent variables. The results showed that the nitrate content at 9 research stations in the Bodri River Estuary was in the range of 0.48-0.8 mg/l and Phosphate 0.8-4.0 mg/l, Kendal Regency was in a fertile/eutrophic condition. The waters of the Bodri River Estuary, Kendal Regency show a high level of fertility or eutrophic.

Abstract

The rising cost of petalite fuel oil is causing concern for small-scale fishermen, particularly trolley fishermen, in the coastal regions of Ambon City. The public has expressed frustration with the increase, as it has the potential to raise the cost of living and necessities. This study aims to provide a more in-depth understanding of the issue and offer recommendations for Ambon City's fishermen in response to the government's frequent fuel price hikes. The research was conducted between November 2022 and January 2023 using observation and interview methods, along with questionnaires. Ambon City fishermen primarily use diluted Pertalite fuel, which costs IDR 15,000 in Laha, Hative Besar, and Latuhalat villages, and Rp 13,000 in Seri Village. Fishermen from different villages use differing amounts of fuel, with Laha Village fishermen using 20 liters per trip, Hative Besar Village using 5 liters, Latuhalat Village using 60 liters, and Seri Village using 40 liters. Comparing the income before and after the fuel increase, the results indicate that fishermen's income decreased after the fuel increase, with a decrease percentage of 47.12%

Abstract

Several factors influence the number and type of fish caught in a trap, including the size of the trap, fish activity, mobility, design, bait, soaking time,provision of shelter, moon phase, visibility of the trap in the water material, andtype of funnel. It is important to identify problems related to trap placement so thatthe productivity of fish resources can be optimal. This research aims to analyze thecomposition of fish species caught, length at first capture, and differences in catchrate of bottom traps based on different fishing locations. The research was carriedout from April to October 2023 in Talaga Nipa Hamlet, Waisala District, and WestSeram Regency using experimental fishing methods. The results of the research showed that there were 20 species of fish caught in the waters of Sanahuni Hamlet (Location A), with the most dominant type of fish being Pterocaesio tile, namely31.40%. Meanwhile, in the waters of Haya Pulo Hamlet (Location B), 16 species offish were caught, with the most dominant species being Scarus rubroviolaceus at22.86%. On average, caught fish such as Caesio cunning, Scarus rubroviolaceus andCaesio caerulaurea are caught before they reach maturity. The bottom trap catchrate in the waters of Sanahuni Hamlet (Location A) is higher than in the waters ofHaya Pulo Hamlet (Location B). Differences in the number and types of fish caughtin traps can be influenced by various factors, such as fish migration, foodabundance, oceanographic conditions, trap design and construction, depth ofoperation of fishing gear, and damage to coral reefs due to destructive bomb fishing.

Abstract

The Lombok Strait is one of the strategic choke points frequented by heavy maritime traffic, demanding effective maritime security assurance. To ensure thissecurity, careful maritime control and surveillance are necessary, especiallythrough the use of monitoring tools such as SONAR to detect foreign objects passingthrough the Lombok Strait. This research aimed to analyze the characteristics ofunderwater acoustic wave propagation patterns, particularly in the formation ofshadow zones, using the Bellhop method. Simulations of the Bellhop propagationmodel were conducted using the AcTUP v2.2L Toolbox. Temperature and salinitydepth distribution data from January 01st, 2023, to December 31st, 2023 obtained from Marine Copernicus were used in this research,. The calculation of soundpropagation velocity based on the Medwin empirical equation, with a focus onsource depths of 10, 100, 300, and 500 meters. The simulation results indicated thatthe Bellhop propagation model with a frequency of 100 Hz at a source depth of 300meters produced more shadow zones compared to other source depths. Thesefindings have significant implications for understanding the patterns of acousticwave propagation in the Lombok Strait, providing valuable insights for maritimecontrol and surveillance efforts in the region.

Abstract

Artifficial fee nutrition can be enhanched by adding vitamin C, aiming to suport the growth and survival of female Nile tilapia (Oreochromos niloticus). The addition of vitamin C to feed for the growht an d survival of fish has been extensively studied. However, there is still limited research specifically focusing on female Nile tilapia. The study aims to investigate the effect of vitamin C supplementation in feedd and to determine the optimal dosage for the growth and survival of fimale Nile tilapia juveniles. The research adopts an experimental approach using a Completely Randomized Design (CRD), consisting of 4 treatments and 3 replications. The treatments include A (Vitamin C 200 mg/kg feed), B (Vitamin C 300 mg/kg feed), C (Vitamin C 400 mg/kg feed) and D (Without vitamin C supplementation). Based on the results, the treatment with 300 mg/kg feed provide the best outcome, followed by treatment A and treatment C. The ANOVA analysis results indicate that there is no significant effect on growth (Fcount < Ftable) with a significance value >0.05, while there is a significant effect on survival (Fcount > Ftable) with a significance value < 0.05. Therefore, it is concluded that adding vitamin C to feed does not significantly affect the growth of female Nile tilapia juveniles but results in better growth compared to not providing vitamin C. In addition, of vitamin C significantly affects survival. Keywords: Female Nile Tilapia, Growth and Survival, Vitamin C

Abstract

Cenderawasih Bay is one of the territorial waters of Indonesia which has a fairly high fishery potential. In 2022, the bay's fishery potential reaches 135,140 tons but the utilization rate is still at 0.3, which means that it has not been fully utilized, especially small pelagic fish. This shows the need for an estimation of the distribution of fish in the bay that can take advantage of the hydroacoustic method. This research uses a split beam echosounder SIMRAD EY-60 which is operated at a frequency of 38 KHz and a pulse duration of 1,024 ms to obtain fish distribution data. Environmental parameter data was obtained using data from marine.copernicous.eu at the same time as fish distribution data collection. The distribution of fish also shows a fairly diverse distribution of values with the highest SV value range at -59.7 to -57.4 dB and the highest TS range at -59.4 to -46.7 dB. The distribution of fish was also seen to be more concentrated in areas with warm temperatures and spread evenly in each salinity range with the number of fish detected approaching areas of higher chlorophyll concentration.

Abstract

One of the biomass that can be used for making biogas is fish waste. Based on the research, fish waste has a small c / n ratio so it requires mixing with other organic materials that have a higher c / n ratio. The addition of water hyacinth and cow dung will increase the c / n ratio in the anaerobic process to make biogas. The aim of this research is to analyze the process anaerobically of biogas formation from a mixture of fish waste, cow dung, and water hyacinth. Biogas is made with a variation composition of cow dung (D1), a mixture of cow dung, water hyacinth, and fish waste (D2), and a mixture of cow dung and fish waste (D3).) The Variation ratio of each composition is 1: 0: 0; 5: 1: 1 and 2: 0: 1. The results are the value of volatile solid and total solid for each composition of D1, D2, D3 was 33,600 mg / L, 34,800 mg / L, 33,000 mg / L. Value of Total Solid D1, D2, D3 are 121,800 mg / L, 146,200 mg / L, 174,600 mg / L. Fermentation process lasts for 1 month at a temperature 25oC-33oC and pH 6-7. The rates of degradation of organic compounds for D1, D2, D3 are 0.0058/day; 0.0439/day and 0.0052/day.

Abstract

Uncontrolled use of the Arbes river due to human activities causes pollution, thereby causing a decline in river water quality. This research aims to determine the quality of river water in terms of physical, chemical and biological factors in the Arbes River.This research was conducted from January to February 2019by taking Arbes River water samples using the quadratic linear transect method.The research sampling transect line measurements were carried out horizontally, namely from upstream to downstream of the river.Arbes River water quality analysis testing was carried out at the MIPA IAIN Ambon laboratory.The results of the analysis of the water quality of the Arbes River physically, chemically and biologically have decreased with the water quality criteria based on PP 82 of 2001 being classified as class II quality water which is not intended as a raw source of drinking water but is more suitable for washing and agriculture.Based on determining the Pollution Index (IP) value, the results of the pollution index for use (Pij) in Arbes river water are included in the lightly polluted category.The highest pollution index value for use (Pij) is found in the lower reaches of the river, namely 1.869. Meanwhile, the Pij value in the middle of the river is 1.784. And the lowest Pij value is found in the upper reaches of the river at 1.677.
