Abstract

Mangrove Ecotourism Management of Mengkapan Siak which has potential as an ecotourism area is currently experiencing stagnation in its development. The management of mangrove ecotourism in Mengkapan is still sectoral and has not been based on multi-sectoral and multi-dimensional considerations. This study aims to identify the condition of the mangrove ecotourism area by integrating multidimensional aspects (ecological, economic, socio-cultural, legal-institutional and infrastructure-technology) to be able to analyze the sustainability index of each dimension of mangrove ecotourism management, which will then be obtained sensitive attributes that are the key in the formulation of the mangrove ecotourism management strategy. This research was conducted using quantitative and qualitative approaches with survey methods, literature studies and interviews. The data obtained will be analyzed using Rap-Mangrove Analysis which aims to determine the sustainability status of mangrove ecotourism and leverage analysis to determine the sensitive attributes of each dimension. The results obtained that the index value of the ecological dimension is 48.20% (less sustainable), the economic dimension is 37.00% (less sustainable), the socio-cultural dimension is 78.60 (very sustainable), the legal-institutional dimension is 57.30 (sufficiently sustainable) and the infrastructure-technology dimension of 68.70 (sufficiently sustainable). Therefore, the development strategy that can be carried out is the rehabilitation of the mangrove ecosystem, increasing education to the local community, involving all stakeholders, as well as compiling and establishing standard management rules with legal force.

Abstract

The research objective was to analyze the environmental sanitation and behavior of food handlers with the vector density of cockroaches in the Dumai Port canteen. It is an observational research with cross sectional method and quantitative data type. The research location was at the Port of Dumai canteen with the first population, namely 24 canteens, total sampling technique, the second 48 food handlers and the third population of 78 buyers with purposive sampling. Relationship analysis was performed using multiple linear regression. With the results of environmental sanitation that meet the health requirements of 20.83% and do not meet the health requirements of 79.17% and the behavior of food handlers as many as 8 (16.67%) have bad behavior, 17 (35.42%) have good enough behavior and 23 (47.91%) good behavior, 6 canteens in medium category and 18 high category canteens. The results of the analysis showed a strong (r = 0.799) and significant (p value = 0.000) relationship between environmental sanitation and cockroach density and a very weak correlation (r = 0.015) between food handler behavior and cockroach density in the Dumai Port canteen (pvalue = 0.946) greater than 0.05 means that there is no relationship between food handler behavior and cockroach density. The economic factor of the price and location purchasing decisions becomes the consumer decision-making process in buying at the Dumai Port Canteen. The suggestion in this research is the need to improve environmental sanitation and increase the supervision of port health workers to reduce the cockroach population in the Dumai Port Canteen.

Abstract

The phenomenon of paddy fields conversion in Kampar Regency which continues to increase from year to year had caused decreasing paddy fields area and threatening food supply capacity. The purpose of this study was to analyze the index and the status of the sustainability of control over the paddy fields conversion and to find out the sensitive attributes of the sustainability of control over the paddy fields conversion in Tambang Sub-District, Kampar Regency. This research was conducted in Aur Sati Village, Balam Jaya Village and Pulau Permai Village, Tambang Sub-District, Kampar Regency from October 2020 to January 2021. The method used was the survey method with a quantitative approach. The sampel of farmers in this study were 88 people who were selected by purposive sampling. Data collection was done by observation, interviews, and literature study. This study used questionnaires as an instrument to collect data.  The analytical method used in this research was the sustainability analysis carried out with the Multi-Dimensional Scaling (MDS) analysis approach with the Rap-Paddy Field tool which has been modified from Rapfish program. The results showed that the control of the paddy fields conversion in Aur Sati Village has been going very well, this can be seen from the sustainability index value of each dimension in the range of 52.4 - 83.9% (fairly - highly sustainable). On the other hand, the sustainability index value of each dimension in Balam Jaya Village ranges from 35.9 - 48.2% (less sustainable), this showed that paddy fields conversion in this village has not been well controlled. While in Pulau Permai Village, the economic dimension had a sustainability index value of 48.2% (less sustainable) and there were 2 (two) dimensions that were classified as fairly sustainable, namely the ecological dimension of 64.4% and the social dimension of 52.3%. These data provided information that the control of paddy fields conversion in Pulau Permai Village is still ecologically and socially oriented, and ignores the economic dimension. There were sensitive attributes that need to be given top priority in planning the sustainability of control over the paddy fields conversion in Tambang Sub-District, Kampar Regency, namely price stability, product markets, traditional leaders, cultivation techniques and availability of RTRW.
