Abstract

Mandor Village has developed as a tradisional gold mining area since years ago. It involved activities that have led to extreme land condition and the release of mining residues, i.e., mercury, to the soils. The study examined the potential of soil bacteria as mercury bioremediation agent based on their population and activity in former mines with different ages. The bacterial population was measured by isolating soil bacteria on solid media using the pour plate method, and the colonies were enumerated during the incubation. The Nutrient Agar (NA) medium was used to obtain the total population, whereas the Salt Base Solution (SBS) was to determine the presence of mercury-tolerant bacteria. The addition of HgCl2 affected the number of the colonies. The colony only grew until the concentration of HgCl2 reached 5 mg/l, and the total colony was larger in older mines. The observation of bacterial activity showed that biotransformation performance was lower when the concentration of mercury was the same as its natural presence in soils (0.1-0.5 mg/l) compared with higher mercury level (1 mg/l). The research showed that lower mercury concentrations in nature reduced the natural ability of bacteria to transform pollutants. This study provides information that can assist the development of a technological approach to control mercury pollution in former traditional gold mines in an environmentally friendly manner using indigenous soil bacteria.

Abstract

Permukaan bumi mengalami perkembangan secara dinamis, tidak hanya pada perubahan jenis penggunaan lahan namun juga pada bentuklahan geomorfologi secara detail. Perubahan dinamis ini disebabkan adanya kebutuhan manusia mengenai lahan. Pulau Jawa memiliki fisiografi yang beragam, hal ini dipengaruhi oleh aktivitas vulkanik dan pengangkatan wilayah serta erosi dan sedimentasi. Kawasan Karangsambung merupakan daerah dengan topografi perbukitan dan tersingkap banyak batuan yang merupakan bukti dari proses tektonik. Singkapan batuan yang banyak dan pada daerah yang realitif luas, mengakibatkan pertanian tidak dominan. Masyarakat cenderung memanfaatkan keberadaan lokasi sebagai tempat untuk penambangan. Penambangan yang dilakukan oleh masyraakat di Kawasan Karangsambung meliputi batuan-batuan yang dianggap memiliki fungsi komersil. Selain itu erosi dan sedimentasi yang tinggi memicu penambanggan pasir pada daerah pengendapan. Penambangan yang dilakukan dilakukan secara luas dan berangsur-angsur menyebabkan permasalahan lingkungan. Pada penelitian ini bertujuan mengetahui dampak dari aktivitas manusia terhadap kondisi alamiah di Kawasan Cagar Alam Karangsambung bagian selatan. Pendekatan keruangan menggunakan data citra penginderaan jauh sebagai identifikasi awal. Hasil yang diperoleh bahwa pada Kawasan Karangsambung terdapat 3 aktivitas manusia yang menyebabkan perubahan bentuklahan, yaitu perubahan dari dataran aluvial menjadi dataran banjir dan ledok fluvial, perubahan sinuositas sungai akibat sedimentasi dan longsoran akibat pemotongan lereng, serta perubahan dari perbukitan intrusi diabas menjadi lahan rusak topografi datar. Perubahan-perubahan ini mengakibatkan dampak buruk bagi lingkungan, sehingga diperlukan penanganan dari berbagai pihak.

Abstract

Traditional gold mining activities release mercury into the environment, creating a major concern for the Indonesian governments today. In situ bioremediation, which draws on the activities of indigenous soil bacteria for the recovery of mercury-contaminated land, has never been conducted intensively in the country. This research set out to determine the most efficient in situ bioremediation strategy for this purpose. It took place in Mandor Village, Landak Regency, Kalimantan Barat-Indonesia. During the experiment, four groups of sampling plots were made into triplicate and given various treatments: a. nutrient addition, b. aeration, c. pH neutralization, and d. without nutrient addition and aeration as a control. pH neutralization was conducted in all sampling plots by adding lime until soil pH of ±7 was achieved. The experiment was performed during both rainy and dry seasons to determine the influence of seasonal weather. Total mercury levels of each plot were measured on day 0, 30, 60, 90, and 120, and the effects of treatments and time on mercury depletion were analyzed by two-way ANOVA (P<0.05), followed by a post hoc test to identify the best treatment and optimum time for in situ bioremediation. The results showed that the best time to conduct this bioremediation was in the rainy season by applying nutrient addition and aeration for 90 days on soils with neutral pH; these stimulations could remove ±89.6% of the mercury. This bioremediation technique is a novel technological approach in land recovery that local governments can adopt to restore soils contaminated with mercury from traditional gold mining.

Abstract

Proses karstifikasi memegang peranan yang sangat penting dalam perkembangan bentuklahan karst. Pengetahuan tingkat perkembangan karst merupakan tolak ukur dalam suatu upaya pengelolaan karst. Penelitian ini bertujuan untuk mengetahui tingkat perkembangan karst di daerah peralihan antara Basin Wonosari dan Perbukitan Karst Gunungsewu. Metode pengumpulan data dilakukan secara tidak langsung dengan interpretasi visual terhadap DEMNAS (Digital Model Elevation), foto udara tahun 1993 dan citra landsat dilakukan untuk memperoleh semua informasi morfologi dan data morfometri bentuklahan karst yang meliputi dolina, bukit karst, dan lembah karst. Hasil interpretasi tersebut disesuaikan dengan hasil pemotretan Unmanned Aerial Vehicel (UAV) dengan drone dan validasi lapangan dengan pengukuran morfometri dolina, bukit karst, lembah karst pada beberapa lokasi dengan teknik purposive sampling. Tingkat perkembangan karst dinilai dengan indeks cekungan, orde dolina dan tahapan perkembangan karst. Hasil penelitian menunjukkan perbedaan tingkat perkembangan karst di daerah peralihan karst dan Perbukitan Karst Gunungsewu. Tingkat perkembangan karst pada daerah peralihan dikategorikan sebagai kawasan karst dengan perkembangan tahap muda atau dapat dikategorikan sebagai fluviokarst, sedangkan Kawasan Karst Gunungsewu sudah mengalami perkembangan karst dewasa atau dapat dikategorikan polygonal karst. Pemanfaatan dan pengelolaan karst harus dilakukan secara berkelanjutan dengan tetap menjaga kelestarian sumberdaya alam dan keberlangsungan proses karstifikasi.

Abstract

Karst area is highly susceptible to changes to climate parameters. One of the parameters is rainfall variability. In addition to shaping the condition of water resources, rainfall in the Gunung Sewu karst area determines the nature of crop and livestock of the agriculture sectors―the local population's main economic activities, warranting the significance of the rainfall variability studies. Rainfall variability in karst areas also affects disaster conditions such as drought and floods. However, due to insufficient meteorological data in quality and quantity, there has been no rainfall variability studies conducted in this locality. The research intended to analyze rainfall variability in the Gunung Sewu karst area in 1979‒2013 by utilizing rainfall predictions from satellite images that many scholars had tested in different locations and recognized as having good quality. In the analysis, mean monthly rainfall was calculated, and the trends of annual rainfall and average rainfall intensity, dry and rainy seasons, the number of rainy days, and the effect of ENSO (El Niño Southern Oscillation) on rainfall were analyzed. The research data were 35 years of daily rainfall records derived from the National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR). The analysis results showed that the mean rainfall, number of rainy days, and rainfall intensity had an increasing trend. Also, El Niño quantitatively influenced the rain in the Gunung Kidul karst area.

Abstract

The Plaosan Temple which was built during the eighth and tenth century AD is one of four temple complexes in the Prambanan area, Central Java-Indonesia. On going excavation in the temple complex discloses the occurrence of canals along the outer fences. The canals are eight meters wide and four meters deep. This article aims at reconstructing archaic river course and groundwater condition due to the construction of the canals. Aerial photo interpretation, excavation, ground water level measurement and valley morphology measurement reveal an anomaly of the nearest river in the temple complex. The river had seemingly been bypassed south-eastward to its tributary just before entering Plaosan Temple complex. Groundwater level dropped and its flow direction changed from nearly southward to south-eastward direction. These phenomena indicate that the canals were groundwater-discharged canals.
