Abstract

The conversion of tropical peat forest to other land uses can reduce organic carbon (C) and stable C isotope (?13C) of peat soil. This research aimed at analyzing the soil organic-C and ?13C of peatland with respect to maturity (fibric, hemic and sapric) in five types of peatland use, which included primary peat forest, secondary peat forest, shrubs, oil palm plantations, and cornfield in West Kalimantan. Analysis of peat soil samples includes organic C with Loss in ignition method and ?13C  using an isotope ratio mass spectrometry(IRMS) method. Organic-C at fibric was higher than hemic and sapric, respectively (57.2%, 57.0%, 56.4%), meanwhile, organic-C was the highest on primary peat forest, followed by on secondary peat forest, oil palm plantation, cornfield, and shrubs, respectively 57.1%, 57.0%, 56.4%, 56.0%. The cause of increasing and decreasing organic C and ?13C due to land-use change due to changes in vegetation, burning during tillage, and age of organic matter of peat soil. This condition causes the opening of natural peat ecosystems and changes in anaerobic to aerobic conditions.

Abstract

Sermo reservoir is the only one belongs to Yogyakarta Special Province; it is relatively a new reservoir with the area of 1.9 kilometer square and its capacity of 25 million cubic meter: It started to operate since 1996 as flood control, irigation, water supply, tourism and fishery purposes. As a reservoir it could be considered to be a manmade lake, as its condition nearly similar to a lake. Since it operated (even during construction period) there were some significant environmental changes within the reservoir and in the area around the reservoir due to the human activities. These changes could threat the sustainability of the reservoir itselfThis research aims to identiflr the human activities living around the reservoir and visitors coming to the area, and to evaluate the potensial of the activities to produce wastes which is discharging in into the reservoir; which may threat the sustainability of the reservoir: The observatorium in the field has been conducted in the area of the reservoir and its sorrounding. I t was firund fiom the observation that activities o f fishery using net (karamba), tourism altogether with its facilities, land use around the reservoir for agriculture purposes, mining of class C ore, have given a lot of contribution to wastes (liquid and solids) and sediments into the reservoir: Those activities may cause water quality of the reservoir lo decrease as well as reducing the reservoir depth. Those situation was observed in the northern and north western parts of the reservoir Water quality degradation of the reservoir may threat reservoir as source of domestic water supply, while the sedimentation may reduce the life time of the reservoir The fishery and tourism activities was estimated as a main cause of water quality degradation, beside agricultural and domestic wastes originated from sattlement area around the reservoir: Sediments coming into the reservoir are derived fiom transported and movement of materials from land slide occuring around the reservoir; due to distruction of land in constructing the relatively new ring-road close to the shore line of the reservoir: Of course, the sediment is also coming from rivers enteringdie reservoir. Sermo reservoir is a relatively young reservoir; the early observation of environmental changes of the reservoir could hopely be used as indicator to study ecological changes of the area within and around of the reservoir; and could be used as a comparison to other reservoirs, as well as basic environmental management of the reservoir and its surrounding.

Abstract

Papua is the final fortress of forests in Indonesia. However, floods recently occurred in Jayapura, Paniai, and Manokwari. If causal factors are not identified and early anticipated, the flood will become an annual disaster with more severe impacts. This study aims to identify main factors causing floods using scoring analysis. Data collected include: rainfall, river gradient, water discharge, drainage density, watershed shape, slope and land use. The research results show that the main factor of floods are average daily rainfall in wet month by 86.53 mm day-1 (rather high) with a score of 28, land use dominated by forest and plantation (rather low and medium) with a score of 21, watershed slope dominated by 1-<8% (high) with a score of 5, drainage density of 6.4 (medium) with a score of 3, watershed shape (Rc of 0.30 < Re 0.71) with  somewhat/elongated shape with a score of 2, and river gradient of 0.0062 (low) with a score of 2 respectively. High rainfall causes greater flow of water and runoff. Land use dominated by plantations (21.46%) is thought to be one of the main causes of floods in Masni District. Flood mitigation does not mean that rain should be reduced, but regulates/manages such as stopping the conversion of forest into palm oil plantations, reducing surface runoff by applying soil conservation, making bypass from meandering, dredging sediments, and constructing retaining walls.

Abstract

The study was conducted at the edamame plantation area of PT. Mitra Tani 27 Jember with the size of 31.6 m x 29.8 m. The sampling of imature B. tabaci was done by collecting the samples of  leaves from the five plots of planting. The adult samples were taken by setting some yellow traps with the size of 20 x 30 cm. The results showed that the populations of B. tabaci changed during the growing season of edamame, the older the plants grow, the greater number of the populations. The highest number of B. tabaci  adult population was in the age of 10 weeks after planting, those were 818 B. tabaci. The increase of the B. tabaci  population had a significant correlation with the increase of the predators population on edamame. There were seven species of predators founded at the edamame. The highest number of predator founded was Coccinella transversalis and the lowest number of predator was Coccinella septempunctata. Keywords: Bemisia tabaci Genn., edamame Soybeans, yellow traps, C. transversalis

Abstract

Spring is as one of the water resources potential that can not be ignored. Gunungkidul district has three physiographic units: Baturagung Hills, Wonosari Basin and Gunung Sewu Karst Hills. All of them affect the distribution of springs in the Gunungkidul Regency. On the other hand, physiography will affect the community adaptation to the environment. It will contribute to the springs conservation effort. The purposes of this research are:  1) to identify the characteristics of springs, 2) to analyze the community participation in conserving  the springs as basic information to develop spring conservation models. To identify the socio-economic characteristics and the springs characteristics in the research areas use a survey method. Unit sampling and analysis is done purposively based on three zones: Baturagung Hills, Wonosari Basin and Gunung Sewu Karst Hills. Socio-economic survey was done by sampling on the 90 respondents, divided into 3 zones through direct interviews using quetionare. Quantitative descriptive analysis was performed through statistical tests. The results show that the quality of spring water in all physiographic zones meet to the water quality standard, except those for colli bacteria. The discharge of karst springs in the hills of Gunung Sewu greater than the discharge of the two other zones. The springs distribution is more in Wonosari Basin and Karst Hills of Gunung Sewu than Baturagung Hills. The level of the community participation in springs conservation is mostly done in groups through user spring groups. Generally, socio-economic factors affect to the level of participation in prevention of springs damage.

Abstract

Airtanah karst merupakan salah satu sumbedaya alam yang potensial di kawasan karst Gunung Sewu. Di sisi lain, akuifer karst sangat rentan terhadap pencemaran. Sungai Bawah Tanah Bribin menjadi sumber air utama untuk masyarakat khususnya untuk mendukung kebutuhan air di musim kemarau. Tujuan pene1itian ini adalah: 1) mengetahui karakteristik daerah imbuhan ponor me1alui identifikasi variabel kerentanan (kondisi ponor, lereng, vegetasi, tanah dan batuan); dan 2) mengetahui tingkat kerentanan airtanah terhadap pencemaran dengan metode COP. Ponor, gua, dan dolin diidentifikasi melalui sensus, sedangkan pengambilan sampel tanah secara purposive berdasarkan unit seri tanah. Proses pengolahan data mendasarkan metode COP, yang merupakan akronim C (concentration offlowkonsentrasi aliran), 0 (overlaying layerllapisan pelindung) and P (precipitation/curah hujan). Setiap variabel dan sub variabel mempunyai nilai di setiap ke1as dan dihitung melalui operasi perkalian dan penjumlahan. Hasil menunjukkan bahwa karakteristik daerah imbuhan ponor bervariasi menurut aspekjumlah, ukuran, lokasi dan kondisi ponor; lereng dan vegetasi, jenis tanah dan batuan serta ketebalannya. Tingkat kerentanan airtanah terhadap pencemaran sebagain besar sangat rentan. Faktor yang mempunyai pengaruh besar adalah konsentrasi aliran. Jumlah ponor sebagai imbuhan terkonsentrasi (titik) dari aliran permukaan menyebabkan sangat rentan.

Abstract

The groundwater salinity in Kedung Sub-district, near the coastal area, is the result of the salt water that comes into the aquifers and the salt water seepage from the surface. The broad groundwater salinity is because of the recent land condition that is resulted from the deposition in the ocean. The nature of the groundwater in-Sub-distric from all aquifers consists of 14% saline groundwater, 48% brackish groundwater and 38% fresh water. The number of community that has brackish until saline ground water property is 19.202 people, so that the domestic water need for the community is 1.344.378 liters/day. Such environmental condition makes the residents make some adaptation. The adaptation of the land use aspect is by making the western region as a fishponds region and the eastern one as a rice fields region. Adaptation in community activities is to fulfill the needs by working as farmers (on the rice fields, fish ponds or salt ponds) or as the fishermen. Adaptation is also made to minimize the threat of disasters, such as the manufacture of levees, weirs or dams and diversions to prevent the spread of tidal flooding.
