Abstract

This research was conducted in February 2021 at the mouth of the Dumai River, Rupat Strait. The purpose of this study was to determine the effect of sediment supply from land on changes in bathymetry in the waters of the Rupat Strait based on the analysis of suspended sediment (SSC) and suspended solids (TSS) divided by the area of the study. The method used is a survey method. The results showed that as much as 26,94 tons/year of sediment entered the Rupat Strait and was distributed in the research area. Each part of the research area has a different bathymetric change value. This is presumably due to oceanographic factors in the waters of the Rupat Strait such as strong and weak river currents when entering the sea, the distance between the research area and the sediment supply source, human activities in each part of the study area, erosion along the river and abrasion at the river mouth. the presence of mangrove forests, dominant sediment types, sloping water topography, the cross-sectional width of the river as a sediment supplier, and suspended solids

Abstract

There are many mining sites found around Kampar watershed, specifically in Tambang sub-district. These mining site are scattered in villages, such as Palung Raya village. This research is conducted to analyze the influence of mining to water quality, rate of land erosion, pollutant load, assimilation capacity, social condition and community economy and mining area management. Survey method and quantitative descriptive approach are chosen to collect data from represented population, which are water, soil and the community around mining site. Insitu parameters are temperature, pH, DHL, DO, and exsitu parameters are TDS, TTS, Fe, texture, soil permeability and plankton. Mining activities have yet to influence water quality, but there’s a fluctuation in physical and chemical parameters, and the average of measurement is under the quality standard of PP Number 82 Year 2001, analog with plankton biology parameter, moderate diversity, no show of dominant type and balanced uniformity. The rate of erosion on slope of 0-8 % is 16,1 ton/ha/year with TBES, and on slope of 8-15% is 72,7 ton/ha/year with TBESB. The value of TDS and TSS for assimilation capacity is over the pollutant load from pollutant source. Mining activity has yet to influence the social economy condition of the community around mining sites. It’s because of the owner and employees are from the outside of the community. Water quality management of Kampar tributary is conducted based on the analysis of influence from mining to water quality, rate of erosion, pollutant load, assimilation capacity and social and economy condition around the mining sites.

Abstract

This study aimed to analyze the pattern of sediment transport to the distribution of plankton and fishing ground in the estuary of KamparRiver. This study used survey methods, the study sample was obtained in the field are considered to represent the Kampar River estuary. Then the sampling results in the form of TSS, brightness, temperature, salinity, pH, flow velocity and plankton descriptively analyzed and discussed with reference to data interpretation method by using mathematical models (software mike21 ). The results showed the concentration distribution of sediment at the mouth of the Kampar River in east monsoon amounted to 8.76 million tons / day and in the west monsoon amounted to 7.64 million tons / day. A region prone to silting due to sediment transport is periodically southeastern portion Mendol. Based on the analysis modeling , plankton diversity index tends to be low in the study site so that the waters around the Mendol island excluding strategic area for fishing grounds it is indicated there has been a downward trend in plankton diversity index as the primary productivity . The existence of TSS may hinder the penetration of light that ultimately affect the photosynthetic plankton.

Abstract

The objectives of this study are to identify the pollutant sources location, analyze pollution load and pollution load carrying capacity of BOD (Biologycal Oxygen Demand), COD (Chemical Oxygen Demand) and TSS (Total Suspended Solid) concentrations; The QUAL2Kw methods application for modeling process of the main river were divided into nine reach, where Sibayang River (kilometre 86,629) as the headwater and Mentulik village as the downstream boundaries (km 0). The water samples where selected at ten points, with five of them are located at the main river and the rest of five at the tributaries. The modeling used water quality data on pollutant sources as input and the main river water quality data as a comparison.Based on the results of the study, total pollution load of BOD are 4,83 Tons/hour and total pollution load carrying capacity of BOD are 2,65 Tons/hour, it means a pollution load carrying capacity for BOD has been exceeded for 2,18 Tons/hour. The total pollution load of COD are 8,16 Tons/hour and total pollution load carrying capacity of COD are 8,45 Tons/hour, it means a pollution load carrying capacity for COD has not been exceeded and the main river still capable to recieve the pollution load of COD for 0,29 Tons/hour. Total pollution load of TSS are 55,90 Tons/hour and total pollution load carrying capacity of TSS are 12,45 Tons/hour, it means a pollution load carrying capacity for TSS has been exceeded for 43,45 Tons/hour. Generally total pollution load carrying capacity of BOD and TSS has been exceeded, and a total pollution load carrying capacity for COD has not been exceeded, nevertheless if review is based on river reach, an excessing of BOD pollution load has been occurred at km 18 - 1 for 1, 37 Tons/hour, COD pollution load for 2, 38 Tons/hour at km 45 - 40 and TSS pollution load for 32, 54 Tons/hour in the Teso River

Abstract

In 2019 there were 9 (nine) managers of drinking water from Sikumbang Springs. The management of the Sikumbang Spring water supply business is still carried out individually and traditionally means that the management carried out by the Sikumbang Spring entrepreneur is only limited to exploitation. Management does not include environmental preservation. The purpose of this study was to determine the potential and determine the sustainable management strategy of Sikumbang Springs in Pulau Sarak Village, Kampar District, Kampar Regency. The benefit gained from this research is the balance between environmental, economic and social aspects in managing Sikumbang Spring. and the community as water users / entrepreneurs get information on the potential of Sikumbang Springs in Pulau Sarak Village. Analysis of the projected population of each village in the Kampar subdistrict above can be calculated the number of residents who use clean water. The more accurate results of the largest population is at the end of the planned year, namely in 2029 with a total population of 50.732 people (10-year projection). The potential of Sikumbang Spring based on the value of its debit from March to December 2020 is 247.127.040 liters. The need for clean water for household needs (drinking and cooking water) in Kampar sub-district is 6,3 ((liters / day) / soul), so that the community's water demand in Kampar sub-district in 2019 is 310.697 liters / day. The average daily debit of Sikumbang Springs is 808.272 liters / day. The calculation of the average daily debit of Sikumbang Spring shows that the debit value of Sikumbang Spring exceeds the value of its needs. Therefore, Sikumbang Springs in the study area can be used as an alternative in meeting the water needs of the local community and communities outside Pulau Sarak Village. Based on the results of the SWOT analysis of the management of the Sikumbang Spring, the strategy that can be applied is an aggressive (development) strategy that is maximizing strengths and taking advantage of available opportunities, so as to minimize weaknesses and avoid threats. Sikumbang Spring management must optimize the main function of Sikumbang Spring as a source of clean water in meeting household water needs and improving its marketing system. The role of the community in maintaining and preserving the source of the Sikumbang Spring also needs to be enhanced.

Abstract

At the aim to clarify the relationship between the sandbar  formation and lithogeneous sediment discharges, the sedimentological aspects of the Mesjid River Estuary are revealed by various analysis. The samples of bottom surface sediments and the suspended sediment were collected at 50 stations in the estuary using grab and van dorm samplers. Oceanographic observation were also carried out  at the stations. The Mesjid River Estuary receives lithogeneous sediments mainly from the Mesjid River’s drainage areas which play important role on the formation of sandbar which is shown by  a belt-like area (0.5-1.0 m depth) in the area off the river mouth. The sandbar might become a sandbank in 20 to 40 years later. High suspended sediment up to 354.61 mg/l indicates the river mouth receives lithogeneous sediments. Total of 926  ton/day of the sediments supplied by the river are deposited 0.024 m/year into the area.

Abstract

Studying Singapore Strait waters condition as a form of maritime mitigation is necessary because it is an international shipping lane. The dominant weather changes include rainfall, wind flows, and sea surface temperature (SST). This study aims to reveal the relationship between rainfall and SST activity in the Singapore Strait for over 18 years, from 2002 to 2019. The results showed a negative correlation, where the SST decreases as rainfall increases and vice versa. In addition, the high rainfall and low SST distribution occur in the Western season (December–February). The low rainfall intensity and high (warm) SST distribution occur yearly in the transition from West to East (March–August). Also, the distribution pattern is influenced by rainfall intensity and the water mass from the South China Sea and the Malacca Strait, where the strait is a mixture of these masses. The neural network model confirmed the negative correlation. Hence a small change in SST causes rainfall if it is cooler, and less precipitation if warmer.

Abstract

The purpose of this study was to clarify relationships between socio-economic activities and forest ecology degradations in Kampar Peninsula, Riau Province, Indonesia. Socio-economic and demographic data were collected from seven districts in three regencies, namely district of Kuala Kampar and Teluk Meranti in Pelalawan Regency, district of Sungai Apit and Dayun in Siak Regency, and district of Merbau, Rangsang and Tebing Tinggi in Bengkalis Regency. All data were collected using Simple Random Sampling and Loting Methods.Results of this study revealed that there were close relationships between socio-economic activities and forest ecology degradations in Kampar Peninsula. The population growth and improvement of socio-economic activities caused land use in Kampar Peninsula forest getting higher. Kampar Peninsula forests were deforested about 260,348 ha (34%) in the period of 1998-2005. The highest deforestation (20%) occurred in the period of 2000-2005. Land use on this forest had increased since 1990 (25,256 ha) and had became increasing in 2005 (162,413 ha).

Abstract

Bottom sediment samples were collected at 74 stations in the South Yatsushiro Sea, off the west coast of central Kyushu Island, Japan using gravity corer. 62 core samples were used for bottom sediments analysis and for determination of mercury content. Among these samples, only 5 core samples were used for this study in an attempt to clarify the relationship between the vertical distributions of benthic foraminiferal assemblages (Bulimina denudata) and mercury contents in core sediments. The distribution pattern of sediment median diameter and of the maximum mercury content at some layers of each core show that the fine-grained sediment polluted by mercury were transported both northeastward and southward by weak longshore currents and spread toward north and west across the northern and souhtern part of the South Yatsushiro Sea. Bulimina denudata shows the highest frequency at every layer which has high mercury content ranging from 0.14 to 3.46 ppm, and is comparatively low at all unpolluted layers. The frequency of Bulimina denudata slightly decreased at the layers showing more than 3 ppm. All these signals suggest that Bulimina denudata does not prefer the bottom sediments showing high mercury contents but tolerates mercury pollution.
