Abstract

Exploration and utilization of seashore potency has to be done sustainably. One of the most valuable plants at Krakal Beach, Gunung Kidul is macroalgae which has not been identified and produced well. Krakal Beach is one of the beach tourism area, which has not been developed yet. To increase the income of owners of the shops in this tourism area, a community development had been held from June to October 2013. The target of this activity were women, which work as shop owner, and join the group of shop owner called Kelompok Pedagang Sido Mulyo Pantai Krakal. The participants had been trained four times, i.e. to understand the sea potency and sustainable development; how to make a jam and sweets made from Euchema sp., and also make crispy chips made from Ulva lactuca, one of the commonly found algae at Krakal Beach. Other topics of training were product packaging; and marketing and promoting the product. The result of this community development was increasing of awareness of the participant to explore and utilize the local potency sustainability, and as well as the increasing of their income from unique-local macro algae product.

Abstract

This study aims to evaluate the response of a decrease in the concentration of Cr in the culture medium and to determine the effect of Cr concentration on the growth of Chlorella vulgaris. This study used a completely randomized design (CRD) with 4 treatments and 3 repetitions. These treatments include, K treatment (control), treatment of Cr 1 (addition of chromium concentration of 1 mg / L), treatment of Cr 3 (addition of chromium concentration of 3 mg / L) and treatment of Cr 5 (addition of chromium concentration of 5 mg / L). Each sample was analyzed by AAS. Analysis of the data is using analysis of variance followed by Duncan test. The results of the analysis of metal concentrations decrease of Cr in the culture medium is Cr 3 (1.2834 mg / l), Cr 1 (0.4360 mg / l), Cr 5 (0.4276 mg / l), and K (0.0126 mg / l). Results of analysis of variance F test showed that Chlorella vulgaris gives highly significant effect on decreasing the concentration of Cd metal. While the results of the growth of Chlorella vulgaris during culture is Cr 3 (909.55 cells / ml), Cr 1 (864.28 cells / ml), Cr 5 (659.20 cells / ml), and K (647.15 cells / ml). Results of analysis of variance showed that different concentrations of Cd metal gives highly significant effect on the growth of Chlorella vulgaris. The conclusion is Chlorella vulgaris has the ability as bioremediator chromium with different concentrations, as shown by the reduction of Cd content in the culture medium. Chlorella vulgaris has a polyamine whose role is to protect or as a protection in a contaminated environment.

Abstract

Watershed is the land area that could potentially be a source of water. The main components of watershed ecosystem composed of humans, animals, vegetation, soil, climate, and water. Watershed ecosystem components that are interconnected is going to maintain the quality of the watershed. A common problem in a watershed is the sedimentation due to large amounts of waste, landslides, and erosion. Water and soil conservation efforts in the watershed can be cultivated by maintaining the balance of watershed ecosystem components one of which is the condition of the vegetation diversity. This study intends to analyze the potential of vegetation in water and soil conservation in the watershed. In-depth study based on the results of the analysis of vegetation and 3 sub-watershed namely Keduang, Dengkeng, and Samin which is a sub-watershed in the Bengawan Solo watershed. Analysis of the condition of the vegetation around the sub-watershed Keduang, Dengkeng, and Samin shows that vegetation has an important role in maintaining the quality of the watershed. Vegetation affects the ability of soil to retain water, thus increasing soil water reserves, prevent erosion and landslides in the surrounding watershed. Vegetation potentially in favor of water and soil conservation in the watershed are shrub vegetation, grass, and other plant floor coverings.

Abstract

There was no monitoring specifically on fauna in the reclamation area of PT Adaro Indonesia. The objective of the research was to record fauna species in this area which had been revegetated less than two years ago. Diurnal birds as a main object were recorded through observation point and survey in four reclamation locations, but mammals, reptiles, and amphibians as supporting objects were recorded merely through survey. Data on birds was analyzed based on a five minute unit to obtain both relative frequency of presence and that of location utilization, but those of others were analyzed merely to list their presence. Thirty bird species, 1 mammal, 3 reptiles, and 4 amphibians were identified in the reclamation area, but each 1 species of mammal, reptile, and amphibian was not identified yet. Five bird species were always present in every location, although their relative frequencies of presence varied. They could be categorized as pioneer birds in the reclamation area. Nine bird species were found only in a certain location

Abstract

Perkembangan pembangunan menyebabkan aktivitas manusia di berbagai sektor kehidupan. Kegiatan ini seringkali menghasilkan bahan pencemar yang berdampak terhadap lingkungan. Salah satu pencemaran yang serius adalah logam berat, karena bila terserap dan terakumulasi dalam tubuh manusia dapat mengganggu kesehatan dan menyebabkan kematian. Logam berat seperti Pb (timbal) dan Cd (kadmium) bersifat toksik dan merupakan pencemar di semua media lingkungan. Konsep yang melihat peran tumbuhan sebagai teknologi alami dalam ekosistem guna mengatasi permasalahan lingkungan dikenal dengan istilah Fitoteknologi. Jenis Acanthus ilicifolius (Jeruju) dipilih karena banyak dijumpai dialam pada muara sungai yang kondisi saat ini dimungkinkan tercemar oleh logam berat dari aktivitas industri dan sebagainya. Pendekatan fitoteknologi ini yang digunakan dalam penelitian. Penelitian bertujuan mengetahui kemampuan tumbuhan akuatik Acanthus ilicifolius terhadap paparan logam berat Pb dan Cd, serta konsentrasi yang terdapat pada bagian tumbuhan sebagai metode dalam fitoforensik. Penelitian dilakukan di Teknik Lingkungan ITS selama November 2013 s/d Desember 2014. Parameter yang diamati berupa kandungan logam berat pada media tumbuhan (pasir dan air) serta bagian tumbuhan (akar, batang dan daun), dengan variasi jumlah tiga dan lima individu. Percobaan dilakukan di greenhouse TL-ITS dengan konsentrasi paparan Pb 10.000 ppm dan Cd 400 ppm, kemudian analisis kandungan logam Pb dan Cd di laboratorium LPPM-ITS mengunakan AAS (Atomic Absorption Spectrophotometer). Hasil penelitian menunjukan bahwa Acanthus ilicifolius termasuk tumbuhan akumulator dengan nilai translokasi faktor 1,01 Konsentrasi logam Pb yang ditemukan pada hari ke 15 pemaparan di akar 8.958 ppm, batang 41 ppm dan daun 22 ppm. Sedangkan konsentrasi logam Cd yang ditemukan pada akar 237 ppm, batang 2 ppm dan daun 1 ppm. Sehingga fitoforensik untuk logam Pb dan Cd pada tumbuhan jeruju terletak di akar.
