Abstract

Understanding the vulnerability of livelihoods is very important in identifying and developing alternative livelihoods for communities to achieve their welfare. Alternative livelihoods are intended so that people do not depend their livelihoods entirely on the use of natural resources. Thus, the exploitation pressure on natural resources, especially the coast and the sea can be minimized. The purpose of this study is to analyze the level of livelihood vulnerability of the people in Depapre Bay using the Livelihood Vulnerability Matrix method. The results of the analysis showed that the level of vulnerability of people's livelihoods is in the vulnerable category (2.44), where the variable value is still low in terms of disaster disruption, social networks, savings, means of production, production costs, and fulfillment of basic needs.Keywords: Vulnerability; Livelihood; Coastal Community; Exploitation Pressure; Natural Resources; Teluk Depapre; Papua

Abstract

Urfu Bay is one of the new marine tourism destinations among the Biak Numfor community. This tourist area does not yet have data from scientific studies related to the level of suitability of the region and its environmental carrying capacity, so it is considered necessary to do so. It is feared that the unavailable accurate data about the condition of tourist areas can pose risks to the comfort and safety of visitors, considering these two aspects are the main reference in the management and development of a tourist area. The purpose of the research is: (1) to know the level of conformity of Urfu Bay area as a marine tourism area, and (2) to know the carrying capacity of urfu bay marine tourism area. The research took place from July to September 2020 in the marine tourism area of Urfu Bay, Biak Numfor Regency. The research methods used are surveys with random sampling techniques, observations, interviews, and library studies. The results showed: [1] Urfu Bay marine tourism area is not suitable for coastal recreation activities (1,235) and diving (1,370), while it is suitable for snorkeling tourism activities (2,285), and [2] the carrying capacity of the urfu bay marine tourism area is 176 people per day. The conclusion of this research is that the coastal area of Urfu Bay is not suitable for marine/coastal tourism activities.Keywords: Suitability; Carrying Capacity; Marine Tourism; Urfu Bay; Biak Numfor

Abstract

This study aims to determine the diversity, distribution, and ecological index of coral fish from the Pomacentridae family in the coral reef ecosystem of Jayapura City. Reef fish observations were carried out in April 2020 at seven study sites. The fish observation was carried out at a depth of 3 to 5 m using the Underwater Visual Census method. Ecological indices were determined using PAST software (PAleontological Statistics) version 4.01, while the similarity index between study sites was determined using PRIMER 7 software. The results showed that the number of coral fish species of Pomacentridae family was 35 species with a total of 346 individual fish. The species distribution was very diverse and no fish species were found at all study sites. The diversity index ranges from 0.572 to 2.215 (low to moderate category), the evenness index ranges from 0.431 to 0.886 (medium to high category), and the dominance index ranges from 0.145 to 0.616 (low to moderate category). The diversity index at Base-G, Pulau Kayupulo, and Lampu Merah sites shows the fish community is classified as medium diversity with high evenness. There are similarities between study sites, where the species N. filamentosus contributed to the formation of group A (Base-G and Argapura 1 sites), while P. moluccensis, C. margaritifer, and P. taeniometopon species contributed to the formation of group B (Argapura 2, Pulau Kosong 1, Pulau Kosong 2, Pulau Kayupulo, and Lampu Merah sites).Keywords: Coral reef; Reef fish; Ecological index; Community structure; Similarity index

Abstract

Tubifex Sp. is an alternative feed for the growth of fish larvae and seeds. This study aims to determine the growth of Tubifex Sp. using fermentation media tofu pulp and vegetable waste. The research will be carried out from September to October 2020. Sample Tubifex Sp. taken at the Acai river, Jayapura City. Effective Microorganisms (EM-4) are used as a solution for the fermentation process. After 30 days, weighing is carried out to determine the growth of Tubifex Sp. The results showed that the growth of Tubifex Sp. on tofu pulp media (55.61 g) was higher than the vegetable waste media (46.7 g) and the control variable (35.5 g). There is a significant difference in the average growth of Tubifex Sp. on tofu dregs media with control variables. Otherwise, there is no significant difference between the growth rates of Tubifex Sp. on tofu dregs medium with vegetable waste, as well as between the average growth of Tubifex Sp. on vegetable waste media with control variables. Tofu pulp fermentation is better than vegetable waste as a substrate for the cultivation of Tubifex Sp. The availability of tofu pulp which is quite abundant and easy to obtain is highly recommended as a substrate fermentation medium for the growth of Tubifex Sp.Keywords: Tubifex Sp.; Fermentation; Tofu pulp; Vegetable waste; Fish feed

Abstract

Eel (Anguilla spp.) is a fish that has a perfect tail, dorsal and anal fins. The eel's fins are equipped with visible soft fingers and the three fins are connected to each other, starting from the back to the tail and ending at the abdomen of the body. The thing that stands out from the eel is the presence of a pair of pectoral fins that are visible on both sides of the body which is located behind the head so that it is suspected that the fins are the ears. Identification of eel species is very important for the management of a resource. The ADL/% TL key character comparison is one way of identifying the types of eels that can be applied. Sampling and measurement of water parameters were carried out on 23 to 25 August 2020. From the research results obtained 1 type of eel, namely Anguilla bicolor (ADL/% TL = -0.37 to 4.76) where the eel entered the Yellow ell phase. This Anguilla bicolor eel likes slow-flowing waters (lentic waters) and sandy mud. Overall the water parameters in the Air Ngalam River are still in optimal conditions to support the survival of the eels, namely temperature 28.5 to 29.8oC, salinity 0 ppt, pH 7.1 to 7.4, brightness 96.48%, and flow velocity 23.78 cm/s. Based on statistical tests, the typology of the Air Ngalam river affects the types of eels found.Keywords: Eel; Phase; Typology; Identification
