Abstract

Penelitian ini bertujuan nntuk menganalisis bentuk-bentuk eko-efisiensi, serta keterkaitannya dengan pengelolaan lingkungan. Data yang diperoleh dianalisis secara deskriptif-komparatif. Hasil penelitian menunjukkan, bentuk eko-efisiensi yang dilakukan industri galvanis adalah recycle air limbah yang dihasilkan. Industri galvanis PMDN telah berhasil mendaur-ulang seluruh air limbah yang dihasilkan, sedangkan industri galvanis PMA berhasil mendaur-ulang sebanyak 1.742,2 m 3 atau 46,2 % air limbah yang dihasilkan pada tahun 2004 hingga mencapai 83,4% pada tahun 2008. Di samping itu, industri galvanis PMA telah berhasil mengelola limbah yang bernilai ekonomis, yakni zinc ash dan zinc dross selama kurun waktu 2006-2008, senilai Rp 3.488.910.000,00. Industri farmasi melakukan eko-efisiensi melalui program penghematan air, pemanfaatan kertas bekas untuk amplop gaji pegawai (reuse), penggunaan e-mail, dan pengelolaan barang bekas/limbah nonB3. Pemakaian air awal sebelum program penghematan rata-rata perbulan ± 10.000 m 3 (tahun 2000). Pemakaian air setelah program penghematan rata-rata perbulan ± 4.250 m 3 (tahun 2008) atau turun 57,5 %. Rata-rata penggunaan e-mail perbulan ± 2.500 email per bulan. Rata-rata penjualan barang bekas/ limbah nonB3 yang masih bernilai ekonomis (karton, plastik bekas, dll) ± Rp 5.750.000,00 perbulan. Industri furniture menghasilkan limbah yang bernilai ekonomis, seperti serpihan kayu, serbuk gergaji, dan sisa potongan kayu. Setiap hari rata-rata dihasilkan 30 m 3 serpihan kayu, 12 m 3 serbuk gergaji, dan 7 m 3 sisa potongan kayu. Di samping itu, dihasilkan sisa karton dan gabus rata-rata 2 m 3 per hari. Industri tekstil pemintalan menghasilkan limbah kapas dan benang, serta limbah bekas packing kapas dan serat, masing-masing 40 ton dan 10 colt perbulan, dengan nilai Rp 220.000.000,00.

Abstract

The conversion of tropical peat forest to other land uses can reduce organic carbon (C) and stable C isotope (δ13C) of peat soil. This research aimed at analyzing the soil organic-C and δ13C 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 δ13C  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 δ13C 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

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.
