Abstract

A high quantity of organic waste without proper waste management can endanger public health and environmental sustainability. To reduce the risk that can be caused by organic waste pollution, then there should be a solution. One of them is to make eco-enzyme. Eco-enzyme is a fermented solution from organic waste that can be used as floor cleaner, plant disinfectant, hand sanitiser, plant fertilizer, etc. A good eco-enzyme solution has special properties. One of them is the low-value power of Hydrogen (pH). In this study, other physical properties of eco-enzyme are analyzed. Eco-enzyme was produced from organic waste. Here, Sunkist orange peel and various mixtures of orange peel were used as the main materials of eco-enzyme. The eco-enzyme solutions were carried out for 33 days, accompanied by routine monitoring by reviewing physical parameters such as pH, Total Dissolved Solid (TDS), and Electrical Conductivity (EC) values. The results showed the characteristics of the eco-enzyme product by physical properties are the eco-enzyme has an acidic with a low pH value (<3.6) accompanied by high values of TDS (>1000 ppm) and EC (>1500mS/cm). The finding is TDS and EC have high value whereas usually high EC and TDS are owned by polluted liquids.

Abstract

Pemeriksaan lapisan batuan serta kondisi bawah permukaan memegang peran yang sangat penting dalam upaya pemanfaatan lahan, baik untuk mendukung infrastruktur diatasnya maupun pemanfaatan sumber daya alam yang terkandung didalamnya. Pemanfaatan lahan berhubungan erat dengan pengembangan infrastruktur yang direncanakan. Agar dapat mengurangi risiko potensial dari bencana, penting untuk memperhatikan kualitas dan kemampuan dukungan lahan yang diperlukan. Artikel ini mengulas tentang hasil studi mengenai identifikasi lapisan batuan yang dilakukan kampus Universitas Padjadjaran Jatinangor di bagian utara. Metode yang digunakan dalam penelitian ini adalah metode Electrical Resistivity Tomography (ERT) karena merupakan metode yang memiliki resolusi yang baik dalam pengukuran geofisika dangkal. Data yang dihasilkan dari pengukuran ini adalah penampang kontras resistivitas tanah dan batuan yang berasosiasi pada berbagai aspek seperti kandungan air dalam pori, jenis batuan serta struktur bawah permukaan. Pengukuran ERT dilakukan dengan membuat 11 lintasan baik yang saling memotong maupun saling sejajar. Hasil pengukuran geolistrik resistivitas di daerah penelitian ini menunjukkan variasi kontras tahanan jenis batuan mulai dari 0,5 Ωmeter sampai lebih dari 500 Ωmeter, namun demikian dalam interpretasi yang kami lakukan, rentang nilai tersebut dibagi menjadi beberapa rentang kategori yang disesuaikan dengan maksud penelitian serta kondisi lapangan yang sedang diteliti. Hasil interpretasi terhadap data resistivitas memunculkan informasi dugaan tiga lapisan batuan di antara kedalaman 0 sampai dengan 70 dan struktur patahan minor di sekitar daerah penelitian.

Abstract

This study investigates the impact of vehicular emissions on the physico-chemical properties of topsoil at Padjadjaran University, Jatinangor. Soil samples were analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), magnetic susceptibility ()LFll, magnetic domain properties (), and heavy metal concentrations using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The results showed that while pH values remained within the neutral range (6.03–7.40), elevated EC and TDS values were observed at locations with high traffic density, indicating increased ionic content from anthropogenic sources. Magnetic susceptibility values ranged from 506.7 to 1148.7 × 10⁻⁸ m³kg⁻¹, with all sites exceeding 10 × 10⁻⁸ m³kg⁻¹, confirming the presence of ferrimagnetic minerals, and higher values were found near areas with heavy vehicle activity. The ) values, mostly below 4%, suggest a significant contribution from anthropogenic magnetic particles, dominated by stable single domain (SSD) and multi domain (MD) grains. Heavy metal analysis revealed that most elements (Fe, Mn, Cu, Zn, Al, As, Mg, Ca, K, Ni and Cr) were within permissible limits, except cadmium (Cd), which exceeded background crustal levels, suggesting contamination from anthropogenic sources, including vehicle emissions.

Abstract

Citarum is the longest river in West Java and one of the most polluted rivers in Indonesia and the world. Heavy metals from agriculture, industry, and household waste pollute the Citarum river. Heavy metals enter humans and animals by consuming contaminated food and beverages. Several studies have identified mitochondria as a primary target for heavy metal poisoning, resulting in impaired mitochondrial energy production, induction of oxidative stress, apoptosis, and mitophagy. This study aims to investigate the impact of heavy metals from the upstream and downstream areas of the Citarum river on mitochondrial gene expression of cox4i1, sod2, baxa, mfn1b, and ppargc1a in the skeletal muscle of zebrafish (Danio rerio) using in vivo models for biological monitoring of early detection of environmental heavy metal pollution. This experimental study was conducted from December 2019 to March 2020. The study involved four treatment groups and one control group of zebrafish, which were exposed to river water and sediments collected from two sites in the Citarum river area in December 2019. The biomarker levels were analyzed using multivariate analysis. Although all heavy metal levels except mercury were below the WHO threshold in all samples, this study's results showed that the RT-PCR results indicated that the levels of cox4i1, baxa, and ppargc1a in all samples were generally higher than those in the control. There were significant differences (p<0.05) using multivariate analysis in sod2 in Cibeureum water compared to Cibeureum sediment and ppgarc1a compared to control and Balekambang sediment. In conclusion, heavy metals from the upstream and downstream areas of the Citarum river had an impact on mitochondrial gene expression of cox4i1, sod2, baxa, mfn1b, and ppargc1a in the skeletal muscle of zebrafish. Biomarkers pparc1gc and sod2 could be further studied to identify the most valid and reliable parameters for biological monitoring, which may aid in the early detection of environmental damage to humans and animals.

Abstract

Environmental conditions in aquatic ecosystems could change due to the entry of additional materials, such as heavy metals and magnetic minerals. These materials, referred to as anthropogenic materials, could be derived from human activities. The presence of the materials could affect the magnetic properties and heavy metals content of river water and sediments. We have analyzed magnetic susceptibility and heavy metal concentration in sediments collected from Cisanti Lake. Cisanti Lake is known as “zero kilometers” of the Citarum River. Using the level of heavy metals in sediments, we calculated and evaluated pollution indices in the form of Contamination Factor (CF), Geoaccumulation Index (Igeo), and Pollution Load Index (PLI). The results showed that the magnetic susceptibility of sediments (𝜒𝐿𝐹) was in the range of 317.2 - 2274.9 (× 10-8) m3kg-1, inferring the dominance of ferrimagnetic minerals in sediments. Based on bivariate analysis of 𝜒𝐿𝐹 and the calculated frequency-dependent magnetic susceptibility or cFD (%), domain states of magnetic minerals are clustered at stable single domain (SSD)/multidomain (MD). Pollution indices of CF and Igeo showed that all sample points were contaminated by Cu at a considerable level.  Moderate to significant contamination occurred in the studied area according to the PLI analysis. The positive strong correlation between 𝜒𝐿𝐹 and PLI suggests that magnetic susceptibility serves as a proxy indicator of contamination.

Abstract

The Cirata Reservoir, an important water reservoir in West Java, plays a key role in hydropower generation, irrigation, and flood control. However, increasing sedimentation poses a significant threat to the reservoir’s functionality. This study maps the bottom topography and evaluates flood risks from sedimentation through bathymetric mapping and water level rise simulations. Data was collected from 22 sampling points using Deeper Sonar Pro+, providing precise depth measurements. Depths ranged from 2.1 m to 45.9 m, with an average of 22.4 m and a standard deviation of 13.46 m. The deepest areas are located in the center and near the Citarum River, while shallower areas are found at the estuaries of the Cibalagung and Cisokan Rivers due to sediment deposition. Simulations of water level rise using bathymetric and NASADEM data showed that a rise of up to 15 m would inundate the western, southern, and southwestern regions of the reservoir. Although the total volume of the reservoir is not determined, these findings underscore the need for effective sediment management to sustain the reservoir’s capacity and ecological functions. Further studies are required to estimate the reservoir’s volume and model long-term sedimentation risks to support the Cirata Reservoir's sustainability.

Abstract

Coda wave data from four stations are to understand seismic attenuation on Sumba Island. Specifically, we estimate the quality factor at 1 Hz (Q₀) and its frequency dependence (η) across multiple window lengths (20–120 s) and frequency bands (1–7 Hz) using waveform data from 394 local earthquakes. The aim is to evaluate how these parameters reflect crustal heterogeneity and tectonic activity. Results show that Q₀ increases with window length, indicating that coda waves progressively sample deeper and more homogeneous layers, while high η values at shorter windows suggest significant near-surface heterogeneity. These findings highlight a depth-dependent variation in seismic attenuation and structural complexity. The study reveals spatial variability, with MELO station showing anomalously high Q₀ values, likely due to localized site conditions or deeper structural influences. Sumba’s location within the tectonically active Sunda-Banda arc transition zone further supports these observations. The combination of low Q₀ and high η values confirms high tectonic activity, and the use of coda wave attenuation analysis offers a reliable, parameter-based framework for assessing seismic hazard potential in regions with complex geodynamics. This work fills a research gap by providing empirical data and interpretation for a previously underexplored area in eastern Indonesia.

Abstract

Sarimukti landfill serves as a waste disposal site. Leachate generated from waste accumulation is discharged through pipelines into multiple retention ponds. This study aims to assess contamination levels in leachate deposits by analyzing the magnetic properties and morphology of magnetic minerals collected from four retention ponds, along with measurements of pH, EC, and TDS in the pond water. Magnetic susceptibility values range from 37.4 – 409.5 (×10⁻⁸) m³/kg, indicating ferrimagnetic mineral dominance. The  values range from 0.81% - 5.96%, where  >2% is often associated to pollutant-contaminated soils. A negative correlation between  and  suggests a minor contribution of superparamagnetic grains from pedogenesis. Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS) analysis identifies spherule and hedral magnetic mineral shapes, with O and Fe as dominant elements and minor Ti, indicating magnetite and titanomagnetite presence. Other elements, including C, Mg, Al, Si, K, Ca, and Mn, likely originate from anthropogenic sources.

Abstract

This study aimed to analyze the physicochemical characteristics of soils across different land uses in Jatiroke Village, West Java. Twenty-four surface soil samples were collected from rice fields, plantations, residential areas, and a temporary waste disposal site (TPS) using a stratified random sampling design. Parameters measured included soil color, texture, temperature, pH, electrical conductivity (EC), and total dissolved solids (TDS) through field and laboratory analyses. Principal Component Analysis (PCA) was applied to evaluate parameter relationships and identify dominant drivers of variability. Results showed that rice fields exhibited the highest salinity, primarily linked to the application of nitrogen- and potassium-based fertilizers, while TPS soils were affected by leachate containing organic and inorganic contaminants. Residential areas maintained near-neutral pH and low salinity, and plantations displayed intermediate variability. Descriptive traits such as color and texture varied across land uses but did not strongly differentiate soil conditions. PCA confirmed EC and TDS as the dominant differentiating factors, with pH and temperature contributing secondary variation. These findings demonstrate that fertilizer use and waste leachate are the main causes of elevated soil salinity, emphasizing the importance of monitoring EC and TDS for sustainable land management.
