Published: March 2021

The concept of ecotourism is a form of management of tourist destinations that prioritizes the preservation of tourism resources, both physical and social culture of the local community. Conservation-oriented activities will guarantee an optimal life cycle and utilization time than oriented towards economic growth. Government and businessmen are the components that play a direct role in controlling the orientation and suitability of the Tourism Willingness to Pay (WTP) with the community’s Willingness to Accept (WTA). The analytical instruments models to synergize and orient travelers WTPs and WTA communities, with the support of government and business actors. This instrument includes the acquisition of data on tourists, the local community, the government and businessmen. The data is formulated in the form of WTP and WTA vectors in the conservation-economic growth coordinate system. The activity orientation tendency is determined by the angle between the WTP and WTA vectors against abscissa (conservation axis) and ordinate (axis of economic growth). Input WTP and WTA vector data into the life cycle of a tourist destination will determine the time to achieve optimal utilization of destination resources. This instrument was developed for the analysis and control of the management of tourist destinations. It can be adapted for the management of other resources that confront the interests of certain parties (such as entrepreneurs) with the local community.

Published: March 2021

The Banggai cardinalfish Pterapogon kauderni is a marine ornamental fish with an exceptionally limited natural (endemic) distribution with IUCN Red List status Endangered. An object of national and global concern, conservation efforts have been hindered by misconceptions regarding key concepts (e.g. endemicity) and a lack of routine and standardised monitoring of P. kauderni populations, fishery and trade. This study approached P. kauderni conservation, including sustainable exploitation, from an intra-species biodiversity perspective, based on IUCN definitions and the evolutionarily significant unit (ESU) concept, with a focus on the importance of monitoring. Analysis of monitoring data combined with knowledge of the unusual life-history and unusually fine-scale genetic structure of P. kauderni were used to identify monitoring priorities and methodological recommendations to support holistic P. kauderni management at the ESU level, within the endemic range. Some implications of introduced wild populations and captive breeding were also evaluated. The analysis highlights the need for an inter-disciplinary approach and inter-sectoral collaboration in monitoring for management. In particular, to combine information from field surveys with trade data (e.g. Fish Quarantine records), and to keep long-term records, to avoid shifting baselines due to the current typically limited periods of data availability.

Authors: Irtas Dentri , Bow Yohandri , Rusdianasari
Published: March 2021

The decline in crude oil production in Indonesia is a burden for the Indonesian people. Therefore, Indonesia needs alternative energy or innovation that aims to review the use of petroleum fuels. One alternative energy is the use of hydrogen fuel (H2). Hydrogen gas can be obtained by breaking air compounds (H2O) into hydrogen-oxygen hydrogen gas (HHO) which is brown by electrolysis. Water electrolysis is the decomposition of water compounds into oxygen and hydrogen gas by using an electric current through water. The current will conduct electricity to the electrodes so that a reduction reaction will occur at the cathode and form hydrogen gas. To speed up the electrolysis process, we need an electrolyte solution that conducts electricity. In general, the electrolysis process is carried out to produce oxygen gas and hydrogen gas using alkaline solution. Alkaline solution used is sea water-electrolyte. The solution is a strong electrolyte that can conduct electric current well. The electrodes used are stainless steel pipe which is resistant to corrosion with insulating material added cotton fabric that serves as an insulator or barrier zone between the cathode and the anode. By designing a hydrogen fuel generator, hydrogen gas may be generated based on the effect of electric current. Variations of the electrical current used is 3A, 6A, 9A, 12A, 15A, 18A, and 21A. The higher the electrical current supplied to the production of hydrogen gas will be many more. The production of hydrogen gas is the most widely produced on the current 21A with 0.0478 LPM of hydrogen gas and efficiency hydrogen fuel generator at 12.99%.

National energy demands continue to increase in 2050 in line with economic growth, population growth, energy prices, and government policies. During 2016-2050, the final energy demand growth rate could reach 5.3% per year. For this reason, alternative energy is needed to meet these needs. One of them is by modifying the generator engine that uses fuel oil (gasoline) with gas (LPG and Biogas) by using a 1250 watt generator set with the aim of knowing how effective the performance of the generator engine is after fuel changes are made. The modification of the engine generator is located in the way the fuel enters the combustion chamber, where the modification lies in the rubber boundary between the carburetor and the manifold installed in the main jet. The test time takes 20 minutes. The test uses no-load with 0.1 kg fuel consumption, 160 watts load with 0.1 kg fuel consumption, 350 watts load with 0.2 kg fuel consumption, and 700 watts load consumption with 0.2 kg fuel. For the use of biogas without load, the fuel consumption is 0.03 m3, with a load of 160 watts, the fuel consumption is 0.03 m3, while for larger loads, the engine is unable. From the results of testing on the modified generator set, the highest fuel consumption was obtained with 0.01 kg/minute LPG, and the consumption of fuel with biogas was 0.03 m3/min. From this test, it was concluded that in the material of fuel consumption (LPG), the power generated was 8.571 kW/hour at the cost of Rp. 12.573 and biogas 0.01125 kWh/hour at a cost of Rp. 16.

The pulp treatments were, P1 = pulp of coffee cherries which were kept in a sack for 12 hours before pulping (delayed pulping), P2 = pulp soaked in water for 12 hour, P3 = pulp left in a basket at room temperature for 12 hours, P4 = pulp/husk of dry process coffee, P5 = pulp of wet process coffee, P6 = pulp/husk of wine process coffee (prolonged dried coffee). The results show that the treatments did not affect the cascara beverage antioxidant activity which was between 53-78% DPPH inhibition. However, all treatments lowered tannin contents to about 35 mg/L, except for the P3 and P6 treatments. The cascara beverage caffeine content of P1, P2, and P3 treatments was low, around 0.20%, and about twice of that in the P4-P6 treatments. Cascara beverage of P4 contained the highest total acids and the lowest pH which was 4.18, whereas cascara tea/beverage of the wet process (P5 treatment) had high caffeine and low tannin contents with moderate pH and total acid content.

Some detrimental effects of decaffeination process are attributed to the stability of the chemical composition of green coffee beans, include reducing the antioxidant activity. Ginger (Zingiber officinale) is widely used as an ingredient for herbal beverage due to its well-known antioxidant activity. The aim of this study was to evaluate the effect of decaffeination process on the chemical compounds and antioxidant activity of green robusta coffee beans without or with ginger extract. The result disclosed that the total phenolic contents of decaffeinated- and caffeinated- coffee were significantly higher up to 1.13 and 3.13 mg GAE/mL, respectively, as the increase of ginger extract concentration of 30%. Of the highest concentration of ginger extract, the total flavonoid contents of decaffeinated- and caffeinated- coffee increased up to 2.55 and 13.41 mg QE/mL, respectively, as well as the melanoidin contents, rose until 0.53 nm (decaffeinated coffee) and 1.19 nm (caffeinated coffee). The analysis also found that the highest antioxidant activity determined by 2,2-Diphenyl-1-picrylhydrazyl was observed in the decaffeinated- and caffeinated- coffee (0.20 and 0.46 mmol TEAC/mL, respectively) with the addition of 30% ginger extract. When 30% ginger extract was added into the decaffeinated- and caffeinated- coffee, there was a significant improvement in the antioxidant activity tested by ferric reducing antioxidant power (0.27 and 0.77 mmol TEAC/mL, respectively) and hydroxyl radical scavenging assay (2.10 and 2.66 mmol TEAC/mL, respectively). Regardless of the concentration of ginger extract, this study reveals that decaffeinated coffee has lower antioxidant activity since a lower content of polyphenol, flavonoid, and melanoidin.

Salmonella sp is a cause of Salmonellosis in ducks. One way to kill these bacteria is to use ultraviolet (UV) light. In this study irradiation for 15, 25 and 35 minutes. Salmonella sp bacteria can attack several physiological systems of the body, one of which is the digestive system. This is because bacteria infect ducks through food and drink that has been contaminated with bacteria. To see the effect of Salmonellosis, a blood sample and organ of the ducks were removed every 2 weeks from the treatment. The physiological condition of ducks infected with Salmonella sp can be seen in hematological conditions and histopathological picture of the liver and intestines in ducks that have been infected with Salmonella sp bacteria that have been exposed to ultraviolet. Based on the results of research that has been done, it was found that the illumination of Salmonella sp using UV light for 35 minutes was most effective to weaken the bacteria because the results showed the smallest value compared to other controls and irradiation. Some histological abnormalities were found in the liver and intestines but still in a condition of minor damage because the damage was only found a little. Abnormalities that occur in the liver include bleeding, nucleus picnosis, necrosis and inflammation, while in the intestine found abnormalities include desquamation of epithelial cells, bleeding and proliferation of goblet cells.
