The growth of manfish can be influenced by appropriate feed, so this study aims to find out what type of natural feed is suitable for the growth of manfish with artificial feed comparisons (pellets). The treatments used in this study were 100% artificial feed (petet) as control/P0, 100% Daphnia sp as 1/P1 treatment, 100% Tubifex as 2/P2 treatment, and 50% Daphnia sp and 50% Tubifex as 3/P3 treatment. The parameters observed during the study were absolute weight growth, absolute length growth, survival rate, water quality, and feed conversion ratio. The results showed a treatment that used good natural feed in the long growth of manfish, namely P1 treatment of 100% Daphnia sp feed by showing a figure of 5.27±0.29 cm. The absolute weight growth parameters in good natural feed treatment are P1 treatment of 100% Daphnia sp with a figure of 3.20±0.34 g. The results of the study with feed conversion ratio parameters in natural feed treatment showed the results that P1 treatment experienced high fish appetite because feed needs during the study showed a figure of 11454.02 mg. The lowest survival rate was obtained in the control at 66.67% and the highest survival rate at P1 treatment at 91.67%. The measured water quality parameters are temperature, pH, salinity, and dissolved oxygen which each show numbers in the range of 27-17oC, 00/00, 7-8 and 4-5mg/L.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139621574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to determine the addition of pectin with different concentrations on the quality of red dragon fruit jam sheets. This research is an experimental study using a completely randomized design (CDR) with four treatments and four replications. Data were analyzed using Analysis of Varience (ANOVA) to obtain Duncan New Multiple Range Test (DNMRT) results at level 5%. The research results showed that the effect of pectin with different concentrations provided significant differences (P<0.05) on water content, ash content, sucrose content, crude fiber content, total dissolved solids, degree of acidity (pH), and organoleptic tests. The addition of 0.75% pectin affects the chemical, physical and organoleptic properties of Red Dragon Fruit Jam. Chemical ingredients consist of water, ash, sucrose content, crude fiber content, total dissolved solids, acidity degree (pH), and physical characteristics including taste, color, aroma and texture. A total of 25 panelists liked the organoleptic properties. In conclusion, the effect of adding pectin on the quality of the best jam product is P3 (0.75% pectin addition) so it is more acceptable based on its character and organoleptic properties.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139621271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local ecological knowledge has an important role in informing sound spatial, spatial and temporal management approaches for marine spatial planning. The aim of this research is to identify the ecological knowledge of local communities regarding the mangrove ecosystem and 2) Community perceptions regarding the management of mangrove ecotourism in Talaga Yenelo in Sagea Village and 3). The level of perception of local communities regarding Ecotourism activities. The method used in this research is determining the sample in this research using a purposive sampling method, namely respondents who participate are deliberately selected by researchers according to the criteria of research respondents. To determine people's knowledge and perceptions, it is based on a Likert scale assessment system and multiple linear regression analysis to see the influence of several independent variables on one dependent variable. The research results show that the people of Sagea and Kiya villages have better knowledge of the local ecology of mangrove forests, especially mangrove habitat, factors of mangrove damage and the impact of mangrove damage compared to the function of mangroves. with the level of utilization of the mangrove ecosystem in the villages of Sagea and Kiya varying greatly. While understanding of mangrove ecotourism activities is very minimal, they agree with the ecotourism activities carried out. Therefore, there is a need for follow-up action from the government regarding mangrove forest management based on the mangrove forest environment.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139624776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chicken sausage is a processed meat product that typically contains meat, binders, and fillers. This study aimed to investigate the physical and microbiological properties of chicken sausage with varying concentrations of oyster mushrooms, which are added to improve its quality. The study employed a completely randomized design with three treatments. If a treatment showed a difference, the Duncan Multiple Range Test was conducted. The treatments consisted of J0: 0% oyster mushroom, J1: 1% oyster mushroom, and J2: 2% oyster mushroom. Statistically, the use of different concentrations of oyster mushrooms did not result in a significant difference (P>0.05) in the water binding capacity, breaking power, pH, and total plate count of chicken sausages. However, the addition of oyster mushroom concentrations can improve the physical and microbiological quality of the sausages. The addition of different concentrations of oyster mushroom to chicken meat sausage resulted in a water binding capacity of 39.28-46.12%, breaking strength of 0.4-0.5 kg/cm2, pH value of 6.46-6.56, and total plate count of 1.57-1.86 cfu/g. The treatment that yields the highest water binding capacity (45.06%), breaking power (0.04 kg/cm2), pH (6.56), and total plate count (1.57 cfu/g) is the addition of 1% oyster mushroom concentration. The concentration of oyster mushroom used in the preparation of chicken meat sausages should not exceed 1% of the total sausage mixture.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":" 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139625201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
