Abstract

Aloe Vera is one of prime farming products in Pontianak so that the city government established Aloe Vera Center as the center for research and development of Aloe Vera product. In 2002, Aloe Vera Center also added an agritourism service there. Agritourism in Aloe Vera Center is expected to keep developing and face the challenge to attract visitors. For a unit of government under service sector, visitor is the most important parameter to make development planning. Therefore, as a basis of development planning, a research is needed to measure satisfaction variable in order to analyze visitors’ satisfaction. This study aims to determine the satisfaction variable of visitors who have the highest and lowest values and which variables are the main problems of visitors so that policy makers can use this research as a basis for planning development facilities, infrastructure and further service improvement. There are 100 respondents with the determination of samples from visitors who came. Conducted with non-probability sampling through convenience sampling method. There was a screening at the beginning of the questionnaire where the visitors who were used as respondents were visitors who had finished visiting. This research used Important Performance Analysis method and Customer Satisfaction Index. Research findings showed that from 5 dimensions and 27 variables analyzed, it was obtained that CSI score was 78,54%, which means that the satisfaction level of the visitors of Agribisnis Aloe Vera Center at whole is at the minimum limit, research finding is on the range 77%<X<80%. It means that, if there were no improvement on the attributes, the satisfaction of the visitors would also deteriorate. Besides, from Cartesian coordinate system, it was found that there were five prioritized variables that need to be improved. The researcher concluded that the Aloevera Manager must be giving attention to the parking area. More improving the cleanliness, comfort, neat location. Providing repairs to the Gazebo Facility and adding wudhu place, prayer mats and mukena as a prayer room facility. This needs to be done to increase customer satisfaction and increase visits. Managers must also make satisfaction analysis as a reference for preparing the following year’s budget.

Abstract

Banda export nutmeg and mace commodities which are rich in essential oils make this plant one of the export commodities on the international market. Banda Neira with the sub-district center located on the island of Neira is one of the Districts in Central Maluku Regency which has the highest amount of nutmeg production, and is a natural spice of the Banda Islands and is known as the nutmeg Banda. This study aims to analyze the nutmeg marketing channel Banda in Banda Neira District, Central Maluku Regency. Sampling uses the random sampling method using a lottery. The data analysis method used is a quantitative analysis approach. The results showed that the in-depth knowledge of farmers about the handling of lean crops coupled with the discovery of aflatoxin which resulted in Banda nutmeg being rejected by international markets, this became a dilemma for exporters whose focus was on small farmers who in their post-harvest processing did not meet international quality standards. This is also triggered by the share received by farmers as the main marketing actor, which is much smaller than other marketing institutions that contribute to the Banda nutmeg marketing chain, so that handling and marketing seems not right, and strategies for more efficient marketing channel analysis are needed that is through the role of marketing institutions involved in developing and marketing nutmeg commodities. There was 70 percent of respondents (42 people) involved in the short marketing channel, through subdistrict traders and 30 percent (18 people) farmers engaged in the long marketing channel through village collectors with different levels of prices charged by each marketing agency.

Abstract

The objective of this study was to determine the release of S in paddy soil. The experiment was carried out in the greenhouse which the soil sample was taken from three different sites. The treatment consists of (T0) control, (T1) 0.02 g S pot-1, (T2) 0.04 g S pot-1, (T3) 0.08 g S pot-1, (T4) 0.04 g S pot-1 + rice straw. The concentration of S was measured in soil, surface water (soil solution) and leached water. The results showed that the addition of S increased the available S. In general, concentration of S in soil was high for site 1 and 3. It was possible due to the higher clay content for site 1 and 3 compared to site 2. The higher S concentration in soil solution was obtained by treatment T3 for all sites. Sulfur concentration in leached water was higher for T2 compared to T4. It indicated that rice straw could protect the release of S in leached water.

Abstract

The purposes of the study was to isolate, to characterize, and to identify rhizobacteria from plant rhizosphere growing in gold and copper mine. The isolation of rhizobacteria used N-free semisolid agar media, TSA, and SLP plus heavy metals (HMs), namely Pb, Cd, and or Cu. Isolated rhizobacteria were subsequently characterized for resistance to higher level of Pb, Cd, Cu in SLP media. Cultural and morphological characterization of rhizobacteria were conducted for cell morphology, motility, Gram staining, and biofilm formation. The rhizobacteria identification used sequence analysis of the 16S RNA gene fragments. The results showed that the majority of rhizobacterial from Cu mine site (66.7% of 21 isolates) were resistant to Cu (72150 ppm) while the majority of rhizobacteria from gold mine site (77.8% of 18 isolates) were sensitive to 72 ppm Cu. Majority of Cu in the soil was insoluble as granules attaching to gravel so that rhizobacteria of Cu mine site have been exposed and adapted to available Cu. This fact, explaining that the rhizobacteria’s MIC value was lower than the total Cu level in the soil. Three HMs-resistant rhizobacter (PbSM 2.1, MGR 334, and CuNFbM 4.1) formed biofilms, which was as one of the resistance mechanism to HMs. This research informed that HM contaminated-soil is better source for obtaining HM resistant rhizobacteria than HM uncontaminated-soil. The use four isolation media produce rhizobacteria which was more diverse than rhizobacteria from each isolation medium. Further characterization needs to be done to obtain HM resistant-rhizobacteria which can be used as biofertilizers and phytoremediation agent.

Abstract

Sinbiotic drinks have a very acidic taste, so it is necessary to add sucrose solution to get the best taste. This study aims to determine the effect of adding 65% (v/v) sucrose solution to changes in antibacterial activity of green grass jelly synbiotic drinks during storage in cold temperatures. The finished green grass jelly synbiotic product was given two different treatments, namely the product without the addition of sucrose solution and product with the addition of 10% (v/v) of 65% (b/v) sucrose solution. The product was stored for 28 days at a cold temperature of ± 10oC. Observations were carried out every 7 days for antibacterial activity, pH, total acid, and total lactic acid bacteria. Antibacterial activity was evaluated using the agar diffusion method against pathogenic bacteria including Staphylococcus aureus, Salmonella sp., Bacillus cereus, and Eschericia coli. The results showed that the antibacterial activity, pH, and total lactic acid bacteria of green grass jelly synbiotic drinks both without and with the addition of 65% (b/v) sucrose as much as 10% (v/v) reduced during storage at cold temperatures, while total acid increases. There was no significant difference between the antibacterial activity and the characteristics of the green grass jelly synbiotic drink given 65% sucrose solution and without the addition of 65% sucrose solution. Thus the study concluded that the addition of 65% sucrose solution to increase the preference for the product did not significantly affect the change in antibacterial activity of the green grass jelly synbiotic beverage during storage in cold temperatures.
