Abstract

The negative impact of excessive exposure to agrochemicals in shallot cultivation causes environmental pollution and human health. Biochar has the potential to absorb agrochemical contamination. This research aimed to investigate the effect of providing compost and biochar from agricultural waste on land quality, reducing the concentration of heavy metal cadmium (Cd) and mancozeb pesticide residues in soil and products in shallot. The experiment was carried out in shallot fields in Ngurensiti Village, Pati Regency, Central Java Province. Four different treatments, including combinations of biochar and compost, were applied, along with conventional controls. Data were analyzed using the F test (ANOVA) and Tukey's test using the Minitab statistical program version 16.0. The research showed that using biochar made from sugarcane bagasse, rice husk, corncob, and compost helped more soil bacteria grow and lowered Cd and mancozeb concentrations. In addition, treatment with biochar from sugarcane bagasse waste showed a decrease in Cd and mancozeb concentrations and a more significant increase in bacterial populations compared to other treatments (rice husk biochar and corncob biochar). Although there was a slight increase in Cd concentration in shallot leaves post-treatment, Cd levels in shallot bulbs remained within safe limits. This study shows that using biochar and compost from agricultural waste effectively improves soil quality, reduces heavy metal pollution, and lowers pesticide levels to support sustainable agriculture and protect people's health.

Abstract

This research aims to investigate the factors leading to siltation in Lake Limboto by analyzing its morphometric characteristics gathered through direct field measurements and remote sensing using Geographic Information System (GIS). Lake Limboto covers an approximate surface area of 26.09 square kilometers, boasts a maximum depth of 4 meters, and maintains an average depth of 2.83 meters. The Shoreline Development Index (SDI) stands at approximately 2.57, indicating an irregular shape of the lake's water body, while the Lake Volume Development (VD) index, at 2.12, suggests a generally flat lake bottom. The Relative Depth (Zr) registers at around 0.69%, as observed from the water turbidity level. The lakebed relief in the vicinity of the lake's periphery is predominantly flat and shallow, particularly in the western, northern, and southern regions, with depths measuring less than 2 meters. In contrast, the lakebed relief in the central and eastern sections tends to be less flat but still features depths of less than 4 meters. Siltation in Lake Limboto primarily results from high sediment input originating from erosion processes, agricultural activities, and settlements in the surrounding area.

Abstract

Limboto Lake is one of the lakes in Indonesia that has been degraded due to sedimentation and waste disposal, which will affect the lake ecosystem and its surroundings. This research aims to analyze the Magnetic Susceptibility in Vertical Sediments in the fish pond area of ​​Limboto Lake. Efforts must be made to trace sediment's contribution, which is controlled by lithogenic and anthropogenic components. Vertical sediment samples from Fish Ponds in Limboto Lake were taken at one point with a depth of 15 meters using an XY-1A Spindle drilling machine. This type of research uses survey techniques and laboratory tests that use rock magnetism methods, especially susceptibility parameter analysis using the Bartington MS2 susceptibility meter instrument at a low frequency of 470 Hz and a high frequency of 4700 Hz to obtain information on the concentration of magnetic minerals. The sediment samples tested did not go through preparation, such as sieving and drying, but the unsifted samples were put into the plastic holder to analyze the susceptibility magnetic parameter. The measurement results show that the low-frequency magnetic susceptibility (XLF) value ranges from 1.11 x 10-8 m3/kg to 9.68 x 10-8 m3/kg. The concentration of magnetic minerals in this sample contains paramagnetic minerals, and based on the XFD % value, which ranges from 0.206% to 4.714% with an average value of 1.170%, the magnetic minerals in the samples tend to be dominated by coarse-grained non-superparamagnetic minerals (>0.03 µm) and tend to occupy stable single-domain (SSD) and multi-domain (MD) domains. Magnetic susceptibility parameters tested using sediment samples without going through a sieving process can be used to determine sediment characteristics in lake areas that tend to be controlled by anthropogenic components.

Abstract

Mikroplastik merupakan salah satu jenis pencemaran yang berbahaya baik di darat maupun ekosistem perairan. Dengan menurunnya kualitas perairan merupakan salah satu permasalahan yang berada pada lingkungan danau Limboto yang disebabkan oleh pencemaran dan pendangkalan kondisi danau Limboto saat ini sangat memprihatinkan. Penelitian ini bertujuan untuk mengetahui karakteristik mikroplastik yang terkandung pada air dan ikan mujair (Oreochromis mossambicus)  pada perairan Danau Limboto.  Penelitian ini menggunakan alat mikroskop USB Traveler untuk mengidentifikasi bentuk dan warna mikroplastik. Berdasarkan hasil penelitian yang dilakukan Mikroplastik yang ditemukan pada air dan ikan mujair yaitu fiber, pellet dan fragmen. Warna mikroplastik pada ikan mujair dan air danau Limboto berwarna hitam, biru, kuning, hijau, merah cokelat dan putih.

Abstract

Danau Limboto telah mengalami degradasi yang sangat signifikan yang disebabkan di antaranya adalah tingginya pasokan sedimen dari sungai sebagai inlet danau yang menyebabkan menurunnya fungsi danau baik untuk sektor ekonomi, pariwisata maupun untuk penyeimbang sistem ekologi. Oleh karena itu diperlukan solusi untuk mengendalikan laju sedimentasi di antaranya dengan menganalisis suseptibilitas agar dapat memahami kerentanan terhadap faktor-faktor yang menyebabkan kerusakan danau, yang berdampak negatif terhadap fungsinya. Analisis suseptibilitas pada penelitian-penelitian sebelumnya hanya menganalisis sedimen terhadap permukaan. Sehingga tujuan penelitian ini menganalisis suseptibilitas magnetik pada sedimen vertikal Danau Limboto khususnya di area pertanian dan pemukiman yang sekaligus sebagai area sempadan danau. Metode penelitian ini menggunakan survei dan analisis laboratorium dengan metode kemagnetan batuan pada parameter suseptibilitas dengan menggunakan alat Bartington MS2B yang berkerja pada dua frekuensi. Sampel sedimen tidak melalui proses preparasi tetapi langsung dimasukan ke dalam holder. Hasil penelitian menunjukkan nilai suseptibilitas magnetik berkisar antara 13,4x10-8m3kg-1 hingga 807x10-8m3kg-1. Sementara itu persentase suseptibilitas magnetik bergantung frekuensi (?FD%) berkisar antara 0,161% hingga 1,87% dengan rata-rata 0,903% yang terukur pada 20 sampel. Terdapat semua sampel mengandung mineral ferimagnetik. Penelitian ini dapat memberikan informasi tentang proses-proses fisik dan lingkungan yang mempengaruhi sedimentasi, menjadi penanda sedimen yang dikontrol oleh antropogenik dan litogenik yang masuk ke Danau Limboto.
