Abstract

Evaluation of land capability is a way to use the land (land resources) in accordance with its potential. Land potential assessment is needed, especially in policy development, land use and sustainable land management. The purpose of this study was to evaluate the land use based on the land capability at Danau Buatan Rumbai cathment area, erosion predicting on land use and assess soil and water conservation that can be applied in Danau Buatan Rumbai cathment area. The results of this study indicate that the land use in Danau Buatan Rumbai cathment area according to the land capability (class II, III and IV). The results of erosion prediction is greater than the erosion tolerable (ETol), this suggests that the land use in this area there is no soil conservation efforts. Suggested land use planning is the land for oil palm plantations, rubber plantations and mixed farms require conservation efforts bench terracing, contour planting, soil cover crops and waterways. Agricultural land crops require conservation efforts bench terracing, gulud terracing, mulch crop residues, rotation and crop rotation. The land requiring conservation cover crops and grass canals. Land for residential conservation efforts need to planting trees and ground cover plants. and shrub lands conservation efforts allowed the meeting to be a scrub.

Abstract

A worker who works at a wood furniture industry has high-risk of a sensorineuralhearing loss because he/she is exposed to the noise which exceeds the threshold value.The present research was set to examine the relationship between the noise in theworkplace and a sesorineural hearing loss suffered by a wood furniture industry workerin Pekanbaru. The design of the research was cross sectional. The population consistedof 27 wood furniture industry workers and noise intensity sample was taken in aworkplace of planing and sawing unit at 11 wood furniture industries in Pekanbaru.The independent variables were age, noise intensity (dB), working period (year), dailywork length, the use of hearing protective device. The analysis is based on univariate,bivariate and multivariate and the calculation of prevalence ratio value. The resultsshow that there were two variables which had significant correlations withsensorineural hearing loss, namely working period 16 – 30 years (RP = 4.024; 95% CI= 1.476 – 10.971) and age 40 – 59 years (RP = 3.200; C1 = 1.547 – 6/619). Theanalyses also show that the prevalence of sensorineural hearing loss was very large(76.9%) when working period > 16 years and age > 40 years. Since the prevalence ofworkers with sensorineural hearing loss was high, Manpower and Health Offices weresuggested to do promotive and preventive efforts in order that safety and health of thewood furniture industry workers could bemaintained.

Abstract

The research was conducted in January - March 2019. This study aims to map and analyze changes in the area and density of mangrove vegetation based on NDVI values and community structure in the Muara Sungai Gangsal, Indragiri Hilir Regency. To analyze the area and density of NDVI using Landsat 5 TM satellite imagery in 2008 and Landsat 8 OLI/TIRS in 2018. Analysis using ArcGis 10.3 software. The calculation of mangroves based on community structure used the Transect Line Plot method at 6 stations for community structure sampling. The area of mangrove vegetation in 2008 was 2,706 ha and in 2018 it was 2,693 ha. The results of the analysis of mangrove vegetation area from 2008 to 2018 there was a reduction of 13 ha. The NDVI value for 2008 criteria is rarely 133 ha, while 2.009 ha are wide and 564 ha is dense. The NDVI value of the 2018 mangrove vegetation is rarely 16 hectares, while 2,135 hectares are in the area and 542 hectares are dense. Based on the analysis of mangrove density in 2018 at 6 sampling point stations ranging from 866 ind/ha to 1,522 ind/ha. Density criteria are rarely detected at station I with a density of 922 ind/ha and station II with a density of 866 ind/ha. The criterion of moderate density was detected at station V with a density of 1,255 ind/ha and station VI with a density of 1,044 ind/ha. Criteria for solid density were detected at station III with a density of 1,522 ind/ha and station IV with a density of 1,511 ind/ha.

Abstract

Mangrove forests have many roles, which can be grouped into biological, physical-chemical, and economic roles. Grey mangrove (Avicennia sp) fruit has the potential as a raw material for cakes that are still underutilized. The purpose of community service is 1. To increase the value of mangrove ecosystems through the processing of grey mangrove as ingredients for making cakes in Sungai Kayu Ara Village, Sungai Apit District 2. To increase the types of cake making materials for communities around mangrove forests in particular, and 3. Improving the community's economy which continues to increase public awareness to preserve the mangrove ecosystem in Sungai Kayu Ara Village, Sungai Apit District. The results of this counseling activity showed that the participants seriously listened to the material delivered by the extension team from beginning to end. The participants can understand the material presented well and play an active role in the question and answer session, discussion, and directly involved with the speakers and students in making muffins and puddings. As many as 90% of participants who never knew the gey mangrove fruit could be turned into flour after counseling became all of them. Participants who previously only 15% knew of the potential of fires for baking ingredients after counseling activities became 100% understood. As many as 90% of participants believe that with the increased economic value of mangrove forests, mangroves can be sustainable

Abstract

Mapping of coastline changes helps in coastal development and monitoring. The city of Dumai, on the east coast of Riau Province, has undergone significant and radical changes caused by the intervention of humans and nature over the past three decades. This study mapped and measured the rate of change of the coastline of Dumai City for 30 years. The Landsat (TM, and OLI) image series, 1990, 1999, 2008, and 2020 became a data source to generate coastlines through on-screen digitization techniques, then to study the temporal behavior of coastlines using the Digital Shoreline Analysis System (DSAS) and geographic information systems to describe the spatial and temporal variations of coastlines. The results showed that the coastline length during the observation ranged from 123,14 to 125,23 km, while the average accretion rate was 1.17 meters per year while the average abrasion rate was 2.04 meters per year. Those rates of change affected coastline expanded to the sea for 60,82 hectares and eroded 760,20 hectares coastline to the land.

Abstract

A clean and healthy lifestyle (CHL) is a health behavior which comes from one’s own awareness sothat a family member or a family could help him/herself with his/her health problems. To apply theCHL among the family or family members, the Health Department of Republic of Indonesia hascreated a health promoting program and has been decided as a flagship program. However, thenational health survey (2010) indicated that CHL nationally was still far from the minimal target(65%) of the year. The same thing goes to the implementation of the CHL in Sekijang Sub-district,Pelalawan Regency. Pelalawan Regency Health Profile shows that of 2010 households monitored,only 38% had had CHL inclusion. The present research seeks to investigate the correlation betweenthe community empowerment strategies and the individual CHL increase of families among theplantation community within the working area of Seikijang Community Health Center, PelalawanRegency. The data were calculated using Univariat and Bivariat analysis of Chi-Square. The resultsshow that there is a significant correlation between the community empowerment strategies and theindividual CHL increase in Seikijang Sub-district. The strategies shows that there is a significantcorrelation between advocacy and individual CHL, p value 0.007 < 0.005. then, there is a significantcorrelation between the community empowerment and the individual CHL increase, p-value 0.001 <0.05. There is a significant correlation between the atmosphere management and the CHL increase, pvalue 0.000 < 0.05 in Seikijang Sub-district. It is suggested that all parties be more proactive in theCHL program. The success of the program would have a positive impact on all parties, either on theHealth Office, the Community Health Center or on the community and each individual in a family.
