Abstract

The concept of Flower of Service was first introduced by Christopher Lovelock, a British service marketing expert. According to this concept, value is constructed by core products and supplementary services. There are two identified supplementary service, first is a supplementary service that acts as deliverer of service or aid in the usage of core products. And second is a supplementary service that strengthens and adds value to the customers. Mean while, physical evidence is recognized as one of the many factors that influence the customers to buy or use the offered services, and customers’ loyalty is a chance for the buyers to become a loyal customers and /or clients. This research is aimed to (1) find out about the influence of flower of service on customers’ loyalty, (2) to examine the influence of physical evidence on customer loyalty, and (3) to find out the influence of flower of service and physical evidence on customer loyalty. The research show that the multiple linear regression equation Y=3,786+0,482 X1+0,348 X2 which means that if flower of service is represented with 1 then the level of customers’ loyalty will increase for an amount of 0,482 and if physical evidence is 1 then the level of customers’ loyalty will increase for an amount of 0,348. The result of coefficient correlation analysis show that r = 0,642 which means that there is a significant relationships between flower of service and physical evidence on customers’ loyalty. The analysis for the coefficient determination proves that flower of service contributes 41,2% in creating customers’ loyalty and the rest of 58,8% was determined by other factors.

Abstract

The company's main objective is to enhance shareholder value and maximize shareholder wealth. One indicator is to increase the value of the company's profits. With the increase in earnings, the company can develop and maintain the company. Ways in which companies improve profits by increasing sales volume. To facilitate the flow of events from producers to consumers, company must make appropriate distribution channels that include quantity pricing and promotion. By choosing the right distribution channels to increase the company's sales volume. Distribution channels in order to achieve an appropriate target, it is necessary to charge the cost of distribution channels, as well as promotion and must be supported by a good sales person. With the appropriate sales person, the sales activities of the producer to the consumer can be achieved. The purposes of this study are (1) To determine the effect of cost distribution channel to sales volume (2) To determine the effect of the number of sales people to sales volume (3) To determine the effect of cost distribution channels and the number of sales people to sales volume. The results showed that the multiple linear regression equation is formed: Y = -135.3771 + 0.061. X1 + 0.330. X2. Sales volume is at the level of the ratio scale -135.3771. If the variable cost distribution channel (x1) increased scale ratio of 1 unit, then the cost of distribution channels will increase by 0.061 ratio scale, and with the assumption that the variables are considered constant number of sales people. If a variable number of sales people (x2) increased the ratio of 1 unit scale, the sales volume will increase by 0.330 scale ratio, and assuming that the number of sales people is considered constant. The coefficient of determination (R2) or variable R square on 0786 sales volume was 78.6%, which means the volume of sales are influenced by independent factors (cost distribution channels and the number of sales people). While the remaining 21.4% is influenced by other variables not included in this study. The correlation coefficient (R) is the sales volume on variable 0887 shows have a very close relationship between the independent factors (cost distribution channels and the number of sale speople) on sales volume, which is 88.7%.

Abstract

This study aims to describe the size distribution of coconut crabs spatially and temporally in Daeo, Morotai Island, North Maluku. The captching was carried out at three stations, namely in areas adjacent to residential areas (station I), steep terrain with varying vegetation (station II), and shallow areas with various vegetation and coconut trees (station III). The collections of samples were conducted using coconut bait and catching directly by hand. Their lengths of cephalotorax plus rostrum (Cp+r) and thorax (TL) and weight were measured. The habitat conditions of natural vegetation were also observed. Data collected in catch (spatial) were analyzed with non-parametric Mann- Whitney (α0.05) and temporal tests with Kruskal Wallis test (α0.05). The results showed that the total numbers of catched coconut crabs were 581 individuals consisted of 314 and 267 males and femalescoconut crabs). The weight ranges of male and female coconut crabs were 50-990 and 50-520 grams, respectively. The ranges of Cp+r on male and female coconut crabs were 43.98-114.72 mm and 43.98-90.67 mm, respectively. The sizes of the TL in male and female coconut crabs were 19.56-54.86 mm and 19.56-48.65 mm, respectively. Non-parametric Mann-Whitney test of the number of spatial coconut crab catched in station I was different from those in station II and stasion III (P<0.05). The numbers coconut crabs catched were not temporally different (P>0.05). The spatial environmental qualities were not different (P>0.05) and the temporal parameters were significantly different (P<0.05) except pH that was not significantly different (P>0.05). Station III had denser vegetation than stations I and II.

Abstract

The area of mangrove Segara Anakan has a high economic value so that there is a high interest to various land uses in this area. This condition leads to the change in ecological function of the mangrove which has impacts on the decreased production of mangrove crabs. This study was desighed to analyze the areas of catching crabs related to mangrove ecosystem. This study was conducted for six months in the 3 mudcrab catching areas (Western Area, Central Area, and Eastern Area). The analysis used in this study was a one way ANOVA statistic for the crabs catching in these 3 catching areas, and a simple linear regression to analyxe the correlation betwen annual crab production and mangrove area. The results showsed that mud crabs catchings in the 3 areas is 5861.7; 6072.87; dan 7689.4 kg were significantly different (P<0.05) and the linear regression between the area of mangrove in Segara Anakan and crab’s production of the Cilacap Regency was Y= 14.951X-88357 with R2 = 0.54. These results described that the number of crabs catching was influenced by the condition of mangrove in the 3 catching areas while the regressionb analysis showed that the decreased mud crab’s production in Cilacap Regency was correlated to the decrease in the area of mangrove Segara Anakan.

Abstract

Lake Matano is an ancient lake that has a high endemicity. Opudi fish (Telmatherina prognatha) is an endemic fish that is vulnerable to extinction and needs to be preserved. The threat of invasive species and habitat degradation can cause a decrease in opudi fish populations. This study aimed to examine the growth parameters associated with growth coefficients and mortality in Lake Matano so that population can be sustainable. The study was conducted at Lake Matano from March 2018 to February 2019. Samples of fish were caught using a net bag measuring 30 m long, 2 m wide with a mesh size of 0.5 inches. Analysis of fish growth was based on total length-frequency data. These data were analyzed using the FISAT II software. The sizes of male and female opudi fish obtained ranged from 30-70 mm. Growth patterns of von Bertalanffy butina in male fish are male Lt = 76.50 [1-e-0.46 (t + 0.47)] and female fish Lt = 74.05 [1-e-0.51 (t + 0.52)]. The total mortality value of male fish was higher (Z = 1.65) compared to female fish (Z = 1.50), the natural mortality value of male opudi fish was lower (M = 0.84) compared to that of female fish (M = 0.91).
