Abstract

Botia fish (clown loach) growth is relatively slow, taking 4-5 months to reach marketable size (2 inch) and 3 years to achieve initial gonad maturation in female and 1 year in male fish. Environmental degradation and overfishing are factors triggering the production of newly potential broodstock. This study aimed to observe the growth response of potential broodstock through rearing technique with and without shelter. Fish were kept inside the aquaria sized 80x40x30 cm with 20 cm water height on the recirculation system. Fish used for shelter treatment were: Total length ± 7.7 cm, height ± 2.09 cm, and weight ± 7.33 g; for no shelter treatment were: Total length ± 6.7 cm, height ± 1.88 cm, and weight ± 4.59 g. Fish were stocked 10 fish / aquarium and fed 3 times / day by at satiation method. Parameters observed were total length, height and weight improvement also water quality. The results showed that growth and feed efficiency had better value when reared with shelter than without shelter.Keyword: Grow-out, Chromobotia macracanthus, shelter

Abstract

There is no society that does not experience change. Likewise with the people in Kilensari Village, Panarukan District, Situbondo Regency. Along with the times, the people of Kilensari Village began to be dynamic. This raises the question 1) What are the aspects that have experienced socio-cultural changes in the activities of the coastal community of Kilensari village? So, what are the factors driving this change? The research method used is descriptive qualitative. The location was chosen in Kilensari Village, Panarukan Subdistrict, Situbondo Regency because this location is the largest fishing village in Situbondo Regency and there is a 1000 km long monument on the north coast highway. The research subjects consisted of village heads, community leaders, wood crafts entrepreneurs. Data collection techniques in the form of observation, and in-depth interviews. The sampling technique is purposive sampling. Based on the results of the study, it can be seen that the aspects that experience changes in the management of wood crafts are aspects of knowledge, aspects of trust, aspects of socio-culture, and aspects of the economic system. While the factors that encourage change are contact with other cultures, people's dissatisfaction with certain areas of life, future orientation, and the value that humans must always try to improve their lives.Keywords: change, social, culture, woodworking.

Abstract

Muncar Beach, Banyuwangi Regency is an area with high disaster risk. Community-based disaster management will be much more effective than formal agencies set up by the state. But it also does not mean that formal institutions are not important. Education, counseling, and public awareness are non-structural/non-physical disaster mitigation activities. This study aims to analyze the level of knowledge and preparedness of coastal communities in Muncar, Banyuwangi Regency in dealing with disasters, and to find out how the community-based disaster mitigation system in Muncar Beach, Banyuwangi Regency is. This research uses qualitative methods with qualitative descriptive research. Data were obtained through observation, in-depth interviews, and documents. The subjects of this research are community leaders, fishermen, and the people of Kedungrejo Muncar Village. The analysis technique in this research is inductive. In this study, the inductive analysis used is an interactive analysis technique. The results show that the paradigm of disaster management at the population level has not changed much and is still associated with myths. Knowledge and awareness of coastal communities about disaster mitigation are still very low.Keywords: Mitigation, Disaster, Muncar, Banyuwangi

Abstract

The study of biodiversity is important in looking at the current condition of an aquatic environment. The purpose of this study is to examine the biodiversity of the fauna in the Progo River in determining the level of fish diversity and the status of fish resources in the Progo river by using a Geographical Information System (GIS). The sampling method was carried out by purposive sampling consisting of 17 stations. The data taken includes coordinate points, the diversity index (H '), evenness index (E), dominance index (D), and relative abundance (Kr), as well as making a map of the distribution of progo river fish using Arcgis software version 10.5. The results showed that the diversity index value (H ') was moderate to high with a value range of 2.24 to 3.83, with a catch composition consisting of 23 species and 11 families. The evenness index value (E) of the progo river ranges from 0.71 to 1.21. Based on this value, the Progo River has an evenness value between species that is relatively even or the number of individuals of each species is relatively the same. Progo river dominance index value ranges from 0.002-0.008, that is, no fish species dominates. The highest relative abundance (Kr) was balar fish (Barbonymus balleroides) = 0.12%, melem fish (Osteochilus vittatus) = 0.11%, uceng fish (Nemacheilus fasciatus) 0.09%, tilapia fish (Oreochromis niloticus) 0 , 08%, while the lowest was kekel fish (Glyptothorax platypogon) and sepat fish (Trichopodus trichopterus) with a value of 0.01%. The results of the analysis of the distribution of fish in the Progo river show that the fish are widely distributed in the river area which has deep and calm water characteristics, this is indicated by the number of catches at each research station.Keywords: Biodiversity, Progo River, Geographical Information System (GIS)
