Abstract

Intensive agricultural practices in the upper land of the Indragiri river bring about problem to  oxbow-lakes spreading out along in the middle and downstream of the river. Danau Sungai Sorik (DSL) typically included to oxbow-lake, situated in the middle part of Indragiri River, one of four big river in Riau Province, Sumatera. Since the catchment area of the lake were totally urban, accordingly the dynamic equilibrium of lake ecosystem were shifted. The lakes were reportedly degraded in terms of hydrological regime, high sedimentation, fully vegetated and low biological diversity. The local government has repeatedly normalized the depth of the lake in related to development of water attraction, restocking of invading species of fish, cage culture and rice field along the edge of the lake. The present papers aimed at characterizing and assessment of physicochemical and biological properties of the water. Further, potential threats on the sustainability of the lake were assessed. Based on chemical properties of water including BOD5, phosphate and Nitrate range were of (3.26-7.43), (0.11-0.13) and (0.229-0.433) m/L, respectively, were categorized into un-equilibrium or slightly polluted. The water transparency appeared low (25-29) cm, the pH of 6.0-6.5) and temperature of 31-32 0C. Apparently, the diversity index (H), dominancy index and similarity index of phytoplankton ranged from (0.9110-1.2211), (0.3201-0.6136) and (0.3939-0.6290, respectively. It suggested slightly dominated by certain species

Abstract

Heavy metals in soil are relatively easy to be degraded by using plants. Certain plants have a high potency to bioaccumulate heavy metals and to be hyperaccumulator by translocating the high concentrated metals from soil into plant tissues without  causing a negative effect to the plants. One of the potential plants is a flat leave Sansevieria, which is relative easy and fast to grow.The research was conducted to evaluate the potency of five flat leave Sanseviera: S. indica “Tiger Blue”, S. trifasciata “Lorentii”, S. aubrytiana “Tiger Strip”, S. kirkii “Coopertone” and S. hybrid “Blue Boy” as the treatment, and was replicated three times. Each replicate consisted of five plants, which were pre-selected from 100 grown plants. Heavy metals (Pb, Cd, Cu and Zn) in the growing media (soil) and plant tissues were analyzed by using Atomic Absorbtion Spectophotometric (AAS). The results indicated that : 1). Pb, Cd, Cu and Zn concentration in growing media (soils) were in a normal range, 2). S. indica “Tiger Blue” had the highest bioaccumulation potency to Cu and high potency to Cd, Zn and Pb. S. trifasciata “Laurentii” had the highest bioaccumulation potency to Cu and high potency to Cd and Pb, 3). S. indica “Tiger Blue” had the highest hyperaccumulator  potency to Cu and high potency to Cd. S. trifasciata “Laurentii” had the highest hyperaccumulator potency to Cu and high potency to Pb.

Abstract

Lake Timbang Bunga Pengantin, an oxbow lake, has been a favorite tourist destination in Kuantan Singingi Regency in the last decade. The lake of 12 ha in area were used for multi purposed locally livelihood indluding tradisional rice field in the bank of the lake, irigation, fishing ground, fish cage culture, floating resdtaurant and water attraction tourism. As such the lake faced heavy burdens and could interferred the sustainability of the lake. To overcome the environmental problem for sustainability of the ecosystem,a management sustainable strategy need to be formulated with multi criteria of consideration. The present study applied multi-dimentional scaling (MDS) approach following RapLake. The result showed that, the sustainability state of Danau Timbang Bunga Pengantin based on ecology, technology, regulation, were 60,6%,  62,8 %, 70,2%,  respectively, which categorized fairly sustainable, while based economy and sociocultural categorized less sustainable which index of  35.3 % and 44,5 %,  respectively. It revealed that 11 atributes namely; water fertility of lake, fish biodiversity, water condition, tourist potency, capital, fishing dependency, infrastructure, law enforcement, fertilizing of rice field, social  conflict and community empowerment, which driven factors of the management of the lake. The management strategy should start on developing supporting tourism facilities such as econo-lodging, home stay, new attraction, road improvement and amenities. Further the management develop a locally unique attraction and increase local knowledge. Another aspect of important was promotion of the tourist destination through media.

Abstract

The former mining area in Tanjungpinang City was found around the Carang River and Senggarang Village. There was sedimentation containing red mud from the rest of the mining activities that covered the mangrove substrate. The impact is expected to affect the life of the surrounding mangroves. One of the dominant species found is Avicennia marina. This study aims to determine the absorption ability of heavy metal A. marina found around the former bauxite mining area of Tanjungpinang City. The study was conducted from April to August 2020. The study was conducted by a survey by sampling the sediment around the A. marina tree and its organs (roots, stems, and leaves) in the laboratory using the Atomic Absorption Spectrophotometer (AAS). The results of the analysis showed that the concentration of Pb in the sediment ranged from 0.2215-0.2711 ppm; Cd concentration ranged from 0.0113-0.0721 ppm; and Cr ranged from 0.0221-0.0633 ppm. The highest average metal concentration value for Pb was in the Carang River (root organ with a value of 2.1691 ppm); Cd metal in Senggarang (stem, 0.0951 ppm); and Cr metal in Senggarang (root, 0.4988 ppm). The phytoaccumulation mechanism of Pb, Cr, and Cd by A. marina is rhizofiltration (TF<1), while the BCF value indicates that A. marina is non-accumulator/low accumulator (BCF < 250 ppm).

Abstract

Rumah Godang or traditional house in Kuantan Singingi is a cultural heritage building. The building is tens or even hundreds of years old, but the building is still preserved. The existence of Rumah Godang is related to socio-cultural activities and environmentally friendly traditional tambul. Recently, there has been a degradation of the function of Rumah Godang and its socio-cultural activities. Therefore, it is necessary to revitalize the socio-culture and building of Rumah Godang. The purpose of this study was to develop a cultural revitalization program and to compile a technical drawing of the Rumah Godang building. This type of research is qualitative research. The research location is the customary state of Sentajo, Kuantan Singingi Regency. The study population was the traditional houses and cultural activities in Kenegerian adat Sentajo. Data collection techniques are through observation and in-depth interviews with key informants, namely traditional leaders and formal leaders which are then analyzed qualitatively. The results of this study are (a) Revitalization of cultural aspects is the socialization delivered by ninik mamak in Rumah Godang or other traditional events, (b) The arrangement of technical drawings of Rumah Godang keeps Rumah Godang original, so that if it is renovated it must be guided by technical drawings.
