Abstract

This research was carried out to produce wine from banana (Musa sapientum) using yeast (Saccharomyces cerevisiae) isolated from grape (Vitis vinifera). The fermentation of the banana wine lasted for 21days. During fermentation, liquor of the fermenting “must” were removed every 48hours from the fermentor for analysis of pH, titratable acidity, specific gravity and reducing sugar using standard procedures.. The results from the experiment showed that Specific gravity of the wine was observed to reduce drastically as the fermentation progresses. The pH of the Banana wine during fermentation increased from 4.16- 4.22 while the titrable acidity of the Banana wine produced increased from 1.05-1.77. The alcohol content of the wine increased from 0.0 to 9%. The higher the fermentation temperature, the faster the conversion of sugars into alcohol and carbon dioxide by the yeast. The flavor and taste was appreciable. This study showed that acceptable wine can be produced from banana with the yeast Saccharomyces cerevisiae isolated from grape.

Abstract

This study aims to measure the biological activity of flavonols in the leaves of Sterculia foetida as an antihyperlipidemic drug. The chemical structure of flavonols contained in the leaves of Sterculia foetida was taken from the literature. The target protein used was 3-hydroxy 3-methylglutaryl coenzyme A reductase and the control was simvastatin. Water molecules have been removed with PyMol v2.5.2 Software. Docking between the target protein and flavonols was performed using PyRx-Python Prescription 0.8 Software. The results showed that flavonol compounds have greater potential for antihyperlipidemia compared to control compounds. The equivalent affinity of 3-hydroxy 3-methylglutaryl coenzyme A reductase for flavonols is -8.3, and the affinity of 3-hydroxy-3-methylglutaryl coenzyme A reductase for simvastatin is -7.9. Flavonol toxicity studies have shown that flavonols are not potentially carcinogenic and did not cause mutations. The absorption of flavonols in water was higher than that of the control compound.

Abstract

Tunicates belongs to Urochordate that inhibit coral reefs ecosystem. The uniqueness of the tunic can be seen from the body shape like a tube with 2 siphons and the body is covered by a protective layer known as the tunic. The present study aims to observe marine tunicate at waters of Badi Island, Pangkajene Regency, South Sulawesi. This research using the Belt Transect method with a length of 20 m and a width of 4 m at a depth of 5 m with 4 station points according to the wind directions. All tunicate inside transect was noted and identified. Identification was based on morphological characteristics. The result shows that there were 18 species of tunicates present in the coral reefs ecosystem of Badi Island.

Abstract

This study aims to analyze and examine the exchange rate of labour fishers on Bagan Rambo fishing gear in Barru district, Barru Regency. The fishers' exchange rate is used to measure the basic needs of fishers, which considers the income and expenditure of the households of the Bagan Rambo labourers. This type of research uses instrumental case studies. Analyze the poverty of fishers as an instrument for understanding their lives. The results showed that the exchange rate of fishers (NTN) of Bagan Rambo workers was lower than one hundred (88,49%), which means the Bagan Rambo labour fishers cannot meet their basic needs.

Abstract

The potential of Maritime Affairs and Fisheries owned by Indonesia becomes a massive opportunity in producing various types of commodities provided by natural resources such as the fishing fish, aquaculture, fishery products, and ecotourism. Based on this, it is necessary to have synergy between the government, the private sector and the community in managing marine fisheries resources that exist today. Of course, with the existing potential, it will become a challenge in its management that can guarantee the sustainability of natural resources and the improvement of the people's economy. This paper examines the opportunities and challenges of the fishing industry in Indonesia using the input and output data of the Directorate General of Maritime and Fisheries Resources Supervision, which are analyzed descriptively using tables and graphs and journal reviews relating to the study.

Abstract

The objective of this research was to assess the financial feasibility of tiger prawns polyculture (Penaeus monodon) with finfish (milkfish, tilapia, and white snapper) using a leased land system and privately owned land. The sample of respondents was determined by purposive sampling technique in which the number of respondents each was 34 people for privately owned land and leased land. The primary data were collected through direct interviews with respondents. To determine the variations in financial feasibility parameters between the two polyculture cultivation systems, the data were examined using quantitative descriptive analysis, business financial analysis, and a t-test. The results showed that the polyculture business of tiger prawns and finfish using privately owned land with leased land had a significant difference in the income parameters, R/C ratio, and return on investment (ROI) and was not significantly different for the payback period (PP) parameter. The average value of the parameters of the financial feasibility analysis are: income of Rp. 7.043.771/year, R/C ratio of 1,44, PP of 4 years 1 month, ROI of 40,97%, NPV of Rp. 35.375.216, IRR of 77.32%, Net B/C 2,98 for privately owned land systems and income of Rp. 4.007.466/year, R/C ratio of 1,28, PP of 4 years 10 months, ROI of 24,88%, NPV of Rp. 21.492.203, IRR of 50,36%, Net B/C 2,12 for leased land system. Financially, the cultivation system on private land is more profitable than the polyculture cultivation system on leased land. However, in general, both polyculture cultivation systems are profitable and feasible to be continued and developed.
