Abstract

Erosi tanah merupakan proses penghancuran, pengikisan, pengangkutan, atau penyimpanan tanah dari materi eksternal, yaitu hujan. Erosi mengakibatkan penurunan kesuburan tanah dan hilangnya top soil sebagai lapisan tanah yang subur untuk media tumbuh tanaman dan berkembangnya akar. Budidaya tanaman di daerah yang berbukit-bukit memiliki beberapa masalah seperti lereng yang relatif curam, kepekaan tanah terhadap erosi dan curah hujan yang tinggi. Pada daerah aliran sungai, erosi dapat mengakibatkan pendangkalan badan sungai karena sedimen tanah yang menumpuk. Tujuan penelitian ini untuk menetapkan besarnya potensi erosi yang ada dan peta penyebaran erosi. Penelitian dilaksanakan di sub-sub DAS Dengkeng Kecamatan Bulu dan Weru, Kabupaten Sukoharjo seluas 288 ha. Titik sampel ditentukan dengan metode purposive sampling dari hasil tumpangsusun peta kemiringan lereng dan tataguna lahan. Parameter penelitian ini adalah nilai erosivitas hujan, bahan organik, tekstur, struktur, permeabilitas tanah, indeks panjang dan kemiringan lereng, indeks nilai C dan nilai P. Pendugaan nilai erosi dihitung menggunakan Metode USLE (Universal Soil Loss Equation) yang dikelaskan menurut Kementerian Kehutanan. Hasil penelitian ini menunjukkan bahwa penggunaan lahan sawah tadah hujan pada kemiringan curam memiliki nilai pendugaan erosi tertinggi yaitu 600,64 ton/ha/tahun atau 40,04 mm/tahun, sedangkan pada lahan pemukiman dengan kemiringan lereng datar memiliki nilai pendugaan erosi terkecil yaitu 4,54 ton/ha/tahun atau 0,30 mm/tahun. Kelas erosi berat memiliki penyebaran paling luas yaitu 175,27 ha dengan penyebaran terluas di Dusun Kedung Lanang, Desa Karangmojo.

Abstract

Mining using an open pit system may lead to a deterioration in the quality of the environment in term of the extent of the cleared land, heavy metals contamination on the overburden rock, the formation of acid mine drainage (AMD) with a pH <5, high level of total suspended solid (TSS), and the content of the metal on it. Several research results on post-mining land indicated a change in the environmental quality of the mine. Handling of the AMD problem can be conducted by several methods, including the active method by spreading calcium oxide (CaO) in AMD with the aim of increasing pH to neutral. The purpose of this study was to study the alternative techniques to manage the AMD using biostimulant. The present study was conducted firstly in the vinil house by using 10 L of AMD water sample with 2 kinds of treatment, i.e. CaO with levels of 0.2 and 0.25. Biostimulant with four kinds of treatment (I, II, III and IV) which resulted from the combination of different types of biostimulants (A, B and C) with different in composition. Secondly, research on the 1000 L of AMD for scaling up applications in the field. CaO and Biostimulant doses were obtained from the first stage of the study. Analysis pH, TSS, Fe, and Mn of the AMD were done on the control, CaO, and biostimulant treatments. CaO treatment resulted in an increase in pH to 6.9, TSS decreased significantly decline so to 60 mg/L. Fe content in AMD decreased to 0.22 mg/L, and Mn levels decreased to 0.12 mg/L on day 10. Biostimulant treatment resulted in increase of pH to pH 6.7. The TSS value decreased to 40 mg/L. Fe and Mn levels decreased to 0.03 mg/L and Mn 2.98 mg/L, respectively.

Abstract

The Bogowonto River estuary is a coastal area in the open water category because it faces the Indian Ocean directly, it has high wave energy, which will cause erosion and abrasion, and the presence of mangrove and pond ecosystems (silvofishery) can support the development of coastal areas as conservation land. So it is necessary to conduct research to examine the influence of soil physical properties on silvofishing and determine the types of mangroves in the Bogowonto River estuary area. The method used was a survey, where soil samples were tested at the Yogyakarta BPTP Laboratory and the Yogyakarta "Veteran" National Development University at a depth of 0–20 cm and 20–40 cm. Sampling was conducted in a zigzag method from the left (near the pond) and right sides of the river. The results of the research found that there are 2 types of mangroves, namely the Tan cang (Bruguiera sp.), which grows far from the coastline and close to fish pond areas (silvofishery), has a has a relatively stable pH, is dominated by clay texture, and has a low salinity level. White Mangrove (Avicennia sp.) grows near the coastline, with a dominant sandy loam texture, low-normal pH, and high salinity levels. Mangroves that grow along the southern river in the presence of silvofishery can help with the deposition process of mud that is transported along the river and maintain the sustainability of fish populations, and litter from mangroves tends to increase the organic matter content of the soil.

Abstract

The eruption of Mount Semeru at the end of 2021 was responsible for emitting volcanic ash with specific characteristics. These unique mineralogy and chemical properties have both positive and negative effects on soil fertility, as excessive heavy metals adversely affect soil, plants, and the environment. Therefore, this study aimed to determine the distribution of volcanic ash cover from the eruption of Mount Semeru and investigate elemental composition as well as mineral characteristics of volcanic ash and soil covered by volcanic ash. The investigation was carried out in Supiturang village, Pronojiwo District, Lumajang, East Java, Indonesia. Sampling was carried out following the toposequence method, covering agricultural land within approximately ± 15 km from Mount Semeru. Pure volcanic ash was collected at sites not contaminated with soil. At the site location, it was found that the depth of volcanic ash cover ranged from “thin” (<2 cm) to “very thick” (>10 cm). The results of SEM and XRD analyses showed that of the pure volcanic ash contained quartz (50%), rock fragments (15%), plagioclase (12%), hornblende (10%), opaque (8%), and pyroxene (5%) minerals. The results of XRF analysis showed that the dominant elements in volcanic ash and soil were silica (Si), aluminum (Al), calcium (Ca), iron (Fe), and potassium (K). Several non-essential heavy metal elements found were Pb, Sn, and As, while rare minerals discovered were Y, Nb, Eu, and Yb at relatively low concentrations. The SEM analysis showed the structure of volcanic ash dominated by prismatic and blocky.

Abstract

Air asam tambang (AAT) merupakan air dengan kandungan pH rendah (<4) dan logam terlarut dalam air limpasan. AAT terbentuk dari bertemunya tiga komponen, yaitu batuan yang mengandung sulfat, air dan udara. Batuan yang mengandung asam (potential acid forming) yang terkupas selama kegiatan penambangan dapat membentuk AAT setelah bertemu udara dan air yang berasal dari paparan air hujan langsung, air limpasan dan rembesan air tanah. Air limpasan yang tercemar tersebut mempunyai pH sekitar 2 – 4 dengan kandungan logam berat berupa Al, Fe, Mn, Cu dan Zn. Metoda dalam pengelolaan AAT terdiri dari sistem aktif dan sistem pasif. Paper ini membahas mengenai pengelolaan AAT dengan menggunakan sistem pasif wetland. Cakupan yang dibahas menyajikan beberapa hal terkait wetland diantaranya: ukuran wetland dan desain wetland yang tepat termasuk keasaman air yang keluar dari tambang (pH), kondisi reaksi oksidasi, laju aliran air serta waktu yang diperlukan dalam proses wetland serta luasan area yang tersedia untuk konstruksi wetland. Manfaat yang dihasilkan dari studi ini dapat digunakan untuk penelitian selanjutnya dalam rangka program pascatambang tembaga dan emas.

Abstract

Incorporating organic materials that contain biochar is gaining traction as a research area for the cleanup of wastewater contaminated with heavy metals. This study intends to explore the potential of biochar-based materials in removing heavy metals from water sources, with a particular emphasis on rehabilitating aquatic environments affected by mining waste. Identifying appropriate literature studies in collecting research data from various scientific publications was used to understand the topic. Several biochar manufacturing processes are generated through pyrolysis, gasification, and Hydrothermal carbonization (HTC). In this field, studies revealed that using most biochar can achieve relatively high metal removal. Research findings indicate that Cu, Zn, Cd, Pb, Ni, Cr, Co, As, Ag, Fe, Al, and Mn are the metal ions that have received the most attention in this field. This study highlights explicitly the effectiveness of biochars made from orange peel, nutshell, compost, rice husk, oak wood, used coffee grounds, durian bark, Phragmites australis corn cob, dregs of cascara, and hickory wood. The findings show that biochars from these materials, especially those produced at high pyrolysis temperatures (≥500°C), can achieve metal removal efficiencies above (≥90%). Various factors can influence the effectiveness of biochar in removing heavy metal ions, including the pH of the contaminated water, the amount of biochar used, the initial concentration of heavy metals, the properties of the biochar, and the specific forms or speciation of the metals. Biochar's ability to draw in and retain metal ions can be influenced by its characteristics, including its surface area and pore sizes. This study highlights the need for more research in this field going forward. It gives a general review of the use of biochar in removing heavy metals from water, particularly contamination in Acid Mine Drainage (AMD).
