Abstract

Soil contamination was commonly found in gold mining location in Selogiri, Wonogiri, and Central Java and need serious attention for remediation action. This study aimed to investigate the mineralogical characteristic of zeolitic tuff and to analyze the influence of its characteristic for lead sorption on soil in mining, as mentioned earlier location. The soil sample was obtained from around the gold mining location. The zeolitic tuff was obtained in two locations in Gunungkidul, Yogyakarta: A and B. Zeolitic tuff samples were then characterized for mineralogy content using polarization microscopes, cation exchange capacity (CEC) by using barium chloride method and XRD (X-Ray Diffraction) analysis. A batch test was conducted on a laboratory scale by shaking zeolitic tuff samples with soil samples in a CaCl2 solution. The solution was then shaken using a magnetic stirrer, and the filtrate was sampled at a specific time interval. The batch test result showed that the zeolite mineral percentage influenced the sorption behavior of zeolitic tuff in the sample and the value of CEC, which the more zeolite mineral and CEC value, the higher of sorption capacity achieved up to 58.8%. Hence, zeolitic tuff investigated in this study has a promising material for the remediation of Pb-contaminated soil in Selogiri, Wonogiri, and Central Java.

Abstract

Batik wastewater produced in the batik industry in Bayat, Klaten Regency, contains chromium and phenol, which pass the wastewater quality standard. This study aimed to evaluate the ability of tuff breccia from the study area to reduce chromium and phenol concentration in batik wastewater. Mineralogical and chemical characterization was conducted to investigate tuff breccia's mineralogical and chemical composition. A batch and regeneration test was conducted to investigate tuff breccia's ability to reduce the chromium and phenol concentration in the batik wastewater. The characterization of tuff breccia indicates that the tuff breccia consists of fragments, minerals (quartz, plagioclase), and clay minerals (smectite and illite). The batch test results show that the grain size of tuff breccia and the pH value significantly influence the ability of tuff breccia to reduce the chromium and phenol concentration in batik wastewater. The regeneration test showed that the tuff breccia would decrease the capability by up to 30 percent after five times of use.

Abstract

Meningkatnya pertumbuhan penduduk membuat pengelolaan lahan harus dilakukan dengan baik. Dalam mengelola lahan, salah satu aspek terpenting adalah daya resap tanah atau infiltrasi. Faktor yang dapat mempengaruhi infiltrasi di antaranya yaitu litologi, jenis tanah, dan sifat fisik tanah (kandungan air, porositas, rasio pori, dan derajat saturasi). Pengujian dilakukan pada 32 titik di Desa Ngalang, Kecamatan Gedangsari, Kabupaten Gunungkidul. Pengukuran laju infiltrasi dilakukan dengan turf-tec infiltrometer dan dihitung menggunakan model infiltrasi Philips dan Kostiakov yang diklasifikasikan dengan klasifikasi Kohnke (1968). Semua parameter dikorelasikan secara overlay dan grafik terhadap laju infiltrasi model Philips yang dinilai lebih baik dibanding model Kostiakov. Hasil korelasi menunjukkan semua parameter memiliki pengaruh terhadap laju infiltrasi. Parameter jenis tanah memiliki hubungan terkecil dengan nilai R2 yaitu 0,0054, sedangkan rasio pori memiliki hubungan terbesar dengan nilai R2 yaitu 0,2603. Berdasarkan laju infiltrasinya, penggunaan lahan daerah penelitian dibagi menjadi empat, yaitu area pertanian dan penggembalaan, perkebunan, perladangan, dan recharge area.

Abstract

The high growth of developed land in the Banyumanik Sub-District, especially in residential and commercial areas, occurred due to the high demand for housing, lifestyle fulfillment, and speculation and investment by the upper-middle-class society. The reduction or loss of land with vegetation cover in the Banyumanik Sub-District increases the potential for flooding due to more significant surface runoff than water absorption during heavy rainfall. This research used integrated spatial analysis to generate information on the critical level of water infiltration in the research area using the Analytical Hierarchy Process (AHP) method. Both primary and secondary data collected will be compiled and subjected to spatial analysis to address the issues at hand. The weight of each parameter class produced by the AHP method is used for modeling and includes infiltration rate, land use, slope, and lithology parameters. The criticality level of the water infiltration zone in the southern part of Banyumanik Sub-District indicates that the water infiltration condition in the research area consists of good class at 13.589%, naturally normal at 18.405%, started to be critical at 16.114%, slightly critical at 20.764%, critical at 18.286%, and very critical at 12.841%. Changes in land use in the research area have become the primary factors causing alterations in the water infiltration conditions. Infiltration wells are one of the solutions to mitigate runoff as part of sustainable rainwater management. The government plays a crucial role as a policymaker in making decisions to address issues related to urban area development towards sustainable development.

Abstract

One of the reasons for the rapid population growth in the 21st century is urbanization. This leads to land degradation, which can result in a lack of water seeping into the ground when it rains in densely developed areas. Most of the water becomes surface runoff that cannot be absorbed by the soil because the runoff exceeds the soil's capacity to absorb water. In response to this situation, research was conducted on the criticality level of water catchment areas in Gunungpati District, Semarang City. The research involved collecting primary data through infiltration rates and lithology taken in the field, as well as secondary data, including information on land use and slope. This data was later verified in the area. The collected data were then analyzed using the Analytical Hierarchy Process (AHP) method by assigning weights to each parameter and sub-parameter. The parameters considered were land use, infiltration rate, slope, and lithology. The weighted values were overlaid to generate a critical level zoning map of water catchment areas in Gunungpati District, Semarang City. The critical level of water catchment areas in the research area can be categorized into "good" with an area of 1307.2 Ha, "normal natural" with an area of 1013.12 Ha, "starting to be critical" with an area of 436.26 Ha, "Slightly critical" with an area of 91.87 Ha, and "critical" with an area of 7.89 Ha, out of a total research area of 2856.34 Ha..

Abstract

Tanah ekspansif dijumpai di beberapa lokasi di Kecamatan Lumbir, Kabupaten Banyumas, Provinsi Jawa Tengah. Keberadaan tanah ekspansif ini mempunyai implikasi terhadap banyaknya kerusakan jalan di lokasi tersebut yang dikarenakan oleh sifat mudah mengembang yang dimiliki oleh tanah ekspansif. Penelitian ini bertujuan untuk melakukan stabilisasi tanah ekspansif di lokasi penelitian dalam skala laboratorium. Tiga sampel tanah diambil di lokasi penelitian dan dilakukan analisis ukuran butir, kandungan mineralogi dan indeks plastisitas. Percobaan laboratorium penambahan kapur dilakukan pada tiga perlakuan yaitu 2,5%, 5%, dan 7,5%. Hasil analisis distribusi ukuran butir, menunjukkan bahwa persentase ukuran butir lempung yang rendah dan didominasi oleh ukuran butir lanau dan termasuk ke dalam golongan loam dan silt loam serta menunjukkan ketiga sampel memiliki gradasi yang cukup buruk. Hasil plotting nilai batas atterberg pada grafik plastisitas, sampel termasuk ke dalam kelompok CH (lempung plastisitas tinggi) dan CL (lempung plastisitas rendah). Analisis mineralogi menunjukkan bahwa sampel tanah tersusun atas mineral kaolinit dan monmorilonit. Kemudian, percobaan dengan melakukan penambahan kapur pada tanah ekspansif dapat menurunkan nilai indeks plastisitas. Penurunan terbesar terjadi pada sampel dengan penambahan kapur 7,5% yang memiliki nilai penurunan indeks plastisitas sebesar 51,23%.

Abstract

Keberadaan industri kerajinan perak di Kotagede, Yogyakarta yang sudah berlangsung lama, menghasilkan limbah cair yang diduga telah mencemari tanah di lokasi industri dan sekitarnya. Penelitian ini dilakukan untuk menginvestigasi kandungan logam berat dalam tanah, yaitu Cu dan Pb, serta faktor penyebarannya di lokasi kerajinan perak dan sekitarnya di Kotagede, Yogyakarta.  Sampel tanah diambil di lokasi penelitian, yang merupakan daerah kerajinan perak dan sekitarnya. Sebanyak 35 titik sampling diambil pada kedalaman 5 cm, 15 cm, dan 25 cm. Analisis ukuran butir, pH, kandungan organik, kandungan Cu dan Pb, dilakukan pada 105 sampel yang telah diambil serta dihitung pula untuk nilai indeks geoakumulasi. Analisis dilakukan dengan menyajikan dalam peta sebaran kandungan Cu dan Pb yang dilakukan secara spasial, maupun secara vertikal menurut kedalaman sampel, yang bertujuan untuk menganalisis penyebaran secara lateral dan vertikal. Hasil penelitian menunjukkan kandungan Cu dan Pb di dalam sampel tanah yang diambil, telah melebihi nilai latar belakang (background) namun masih berada di bawah baku mutu rujukan. Penyebaran Cu dan Pb pada tanah di lokasi penelitian dipengaruhi oleh dua faktor, yaitu faktor alamiah yaitu ukuran butir, pH serta kandungan organik dalam tanah. Sedangkan faktor manusia yang diduga berpengaruh adalah faktor kegiatan industri kerajinan perak yang menghasilkan limbah cair. Untuk faktor lainnya seperti arah aliran air permukaan dan morfologi, diduga kurang berpengaruh terhadap penyebaran Cu dan Pb pada tanah di lokasi penelitian.

Abstract

The extraction and processing of aggregates in quarrying operations leads to environmental degradation through various engineering methods. This study investigated the geo-engineering properties of tertiary volcanic rocks mined from various sites in Sleman and Bantul District, Yogyakarta Province. A total of twelve rock samples were obtained from the study area. This study conducted mineralogical and geotechnical engineering investigations, including microscopic analysis, unconfined compressive strength (UCS) tests, abrasiveness tests (CAI), and rock abrasivity index (RAI) calculations. Mineralogical observation using polarisation microscopy indicated that the rock samples consist of quartz, plagioclase, lithic fragments, and volcanic glass. The UCS test showed varying rock strengths due to resistant minerals in the samples. Similarly, the CAI values varied and were influenced by the quartz mineral content, which is representative of resistant minerals. The Rock Abrasivity Index (RAI) calculation classified the samples as less abrasive, and this characteristic is also affected by quartz content. A significant correlation was observed between the quartz mineral content and the UCS, CAI, and RAI values. This relationship suggests that the quartz mineral content substantially affects the UCS, CAI, and RAI values of the rock samples in the study area. The findings of this study can be used to enhance mining practices and minimize their ecological impact.

Abstract

Aspek geologi lingkungan memegang peran penting dalam perencanaan wilayah. Penelitian ini mengevaluasi beragam parameter geologi, terutama terkait airtanah dan sifat permukaan, untuk memperkuat pengembangan wilayah Desa Bejiharjo di Kecamatan Karangmojo, Kabupaten Gunungkidul. Parameter yang diteliti meliputi kedalaman muka air tanah dan Total Dissolved Soil (TDS), yang diperoleh dari sumur gali dan hanameter, serta karakteristik tanah dan batuan yang didapatkan melalui pemetaan. Temuan penelitian memaparkan tiga zona kedalaman muka air tanah (dangkal <6 m, dalam 6-20 m, sangat dalam >20 m), dua zona TDS (excellent <300 mg/L, good 300-600 mg/L), serta dua zona satuan permukaan (zona tanah dan batuan). Zonasi pengembangan kawasan ditentukan melalui pembobotan setiap parameter dan pengklasifikasian skor yang membaginya menjadi zona sangat mampu, mampu, dan kurang mampu. Zona yang dianggap cocok untuk pengembangan adalah zona mampu dan sangat mampu yang menunjukkan variasi karakteristik lahan dengan kedalaman muka air tanah antara <6 m hingga >20 m, permukaan yang terdiri dari campuran tanah-batuan, dan nilai TDS antara <300 hingga 600 mg/L. Sebaliknya, zona kurang mampu diisi dengan kedalaman air tanah dari 6 m hingga >20 m, permukaan yang merupakan tanah residu, dan nilai TDS antara <300 hingga 600 mg/L. Dominasi tanah residu menjadi faktor utama yang mengkategorikan zona ini sebagai zona kurang mampu karena tanah residu memiliki kualitas pondasi yang kurang dibandingkan dengan batuan.
