Abstract

Reclaimed-mining soil (RMS) is characterized by low fertility, acidic pH, and high heavy metal contents. As a result, adding amendments becomes essential to support plant growth. Therefore, this research measured alterations in the characteristics of RMS, plant growth, and metal accumulation in plants with the co-application of coal fly ash (CFA) and empty fruit bunches of oil palm (EFBOP). In the first experiment, various levels of CFA (0, 75, and 150 Mg ha-1) and EFBOP (0, 25, and 50 Mg ha-1) were added to the RMS and then incubated at 70% water holding capacity for 45 days to determine their effect on changes in soil properties. In the second experiment, four treatments: control, CFA, EFBOP, and CFA+EFBOP were tested in the greenhouse to quantify their effects on the growth and metal accumulation of plants. Results of the study showed that the co-application of CFA and EFBOP significantly affected bulk density, pH, mineral nitrogen (NH4+ and NO3-), available phosphorus, and exchangeable Ca and Mg in RMS. CFA application increased exchangeable Al by 82-160%, while EFBOP resulted in a decrease of 24-119%. CEC decreased with CFA application and increased with the use of EFBOP. Plant growth increased with the co-application of CFA and EFBOP. The addition of CFA to soils results in increasing metal contents in plant tissue; however, the presence of EFBOP reduced the concentrations of metal in plant tissue. These results highlight the potential of CFA and EFBOP, which are industrial and agricultural wastes, as valuable soil amendments.

Abstract

The issue of acid sulfate soil in Indonesia, characterized by high acidity due to pyrite (FeS2) oxidation, produces sulfuric acid and iron oxide detrimental to agricultural productivity. The use of ameliorants such as coal fly ash (ATB) and empty oil palm bunches (TKKS) is expected to improve soil chemical conditions. The study aims to assess the impact of the ATB and TKKS combination on increasing pH, lowering Eh, and reducing soluble Fe concentration in acid sulfate soils, determining the most effective dose. The research method employs completely randomized design (CRD) with various doses of a combination of ATB and TKKS applied to acidic sulfate soil. Observations focus on changes in pH, redox potential (Eh), and soluble Fe concentration post-treatment. Results of study indicated that application of the ATB and TKKS combination given significant effect to increase soil pH and decreased Eh values. Certain dose combinations exhibit higher effectiveness than single treatments. In conclusion, the combined use of ATB and TKKS offers an efficient and environmentally friendly solution to acidity and iron solubility issues in acidic sulfate soils, supporting increased agricultural land productivity.

Abstract

Kebakaran hutan dan lahan merupakan kejadian yang hampir terjadi setiap tahun pada musim kemarau di Kabupaten Banjar. Kondisi ini mengakibatkan kerusakan dan kerugian ekonomi, sosial dan lingkungan yang akan menghambat laju pembangunan dan pengembangan wilayah Kabupaten Banjar sehingga diperlukan upaya pengendalian terhadap kebakaran hutan dan lahan. Penelitian ini bertujuan untuk menganalisis prediksi luas area kebakaran kawasan hutan dan lahan. Prediksi Luas Area Kebakaran Hutan dan Lahan ini dilakukan di wilayah Kabupaten Banjar dengan menggunakan metode regresi linier berganda, analisis dilakukan secara spasial dengan menggunakan software ARCGIS. Prediktor yang digunakan yaitu Indeks SPI, Suhu Muka Laut dan indeks Nino 3.4. Berdasarkan hasil prediksi menggunakan metode regresi linier berganda didapatkan bahwa kebakaran hutan dan lahan di kabupaten Banjar mengikuti pola musim di wilayah tersebut. Pada saat musim hujan luas kebakaran yang terjadi berada di bawah 10 ha dan berada pada kategori aman hingga menengah. Saat musim kemarau luas kebakaran meningkat hingga lebih dari 400 ha dan berada pada kategori sangat rawan. Kecamatan Karang Intan, Aranio, Pengaron, Sungai Pinang, Sambung Makmur dan Mataraman di wilayah Kabupaten Banjar bagian tengah – selatan merupakan daerah/spot yang paling rawan terjadinya kebakaran.

Abstract

Most of swamp soils in tidal land are Acid Sulfate Soils. Acid sulfate soils are the common name given to soils containing iron sulfides (pyrite). The soils are characterized by very low pH and high amount of soluble S and Fe, resulted from oxidation of pyrite when soils are drained.  This study was aimed to determine acidity pattern, iron and sulfate solubility as the impact of the length time of oxidized, the effect of inhibitors application to acidity rate of sulfidic materials and top soils.  The materials are: (1) soils at pyritic layer (sulfidic materials) and (2) soils at 0 – 20 cm from soil surface.  Soils is sampled at Barambai reclaimed area, Barito Kuala Regency, South Kalimantan Province.  In the laboratory soils treated with some ameliorants, that are silica, phosphate and lime applied with dosage 2 t ha-1 with 3 replications times.  The soils incubated for 2 weeks under submerged condition.  After soil incubation, soil exposed to the air for 1 week, 2 weeks, 4 weeks, and 6 weeks.  Parameters of soil analysis include pH, sulfate and iron soluble. Results of this study showed that (1) soil acidity rate of  sulfidic materials more faster than upper soils when soils and sulfidic materials oxidized intensively, (2) at submerged soil condition or high soil water content, the application of ameliorants effective increasing the soil pH of the upper soils, (3) at further oxidized soil condition or lower soil water content, the application of ameliorants inhibited acidity rate of soils and sulfidic materials, and (4) at further oxidized soil condition or lower soil water content, the application of ameliorants increased iron solubility of  soils and sulfidic materials.

Abstract

The use of fish pond mud in improving soil quality is generally still not widely used. This study used various doses of pond mud to determine the effect of pond mud doses on the availability of N and Fe-soluble in Ultisol soil planted with mustard greens. The research was conducted in the Greenhouse in April - May 2022 with a Completely Randomized Design (CRD), five doses of fish pond sludge namely at doses of 0; 0.5: 7.5: 10; and 12.5% applied to Ultisol soil. The results showed that applying fish pond sludge significantly affected soil pH, N-NO3-, N-NH4+ and Fe-soluble. Soil pH decreases due to a reaction between water and Fe compounds that bind OH- and release H+. Whereas N-NO3-, N-NH4+, and soluble-Fe significantly increased due to chemical reactions that produced soluble salts which reacted with water. As for the soil parameters, the effect of pond mud decreases soil pH at all doses of addition of mud and increases N-NO3-, N-NH4+, and soluble-Fe Ultisol, with the best doses of M3 (equivalent to 1 kg mud + 9 kg of soil). There is a relationship between the chemical properties of the soil and the fresh weight of the plants, as evidenced by the increase in the wet weight of the mustard plants.

Abstract

The decline in mustard (Brassica juncea L.) productivity in recent years has been associated with increasing pest pressure and uncontrolled insecticide use. This study aimed to evaluate the effects of neem leaf–based botanical insecticide and the synthetic insecticide methomyl applied at three spraying frequencies on insect damage intensity, number of leaves, plant height, and fresh weight of mustard. The experiment was arranged in a randomized block design with nested treatments and a separate control. The results showed that the application of both botanical and synthetic insecticides reduced leaf damage intensity and enhanced vegetative growth and fresh weight compared to the control. At 21 days after planting, the neem-based insecticide demonstrated a better ability to suppress pest attack intensity (9.39%) than the synthetic insecticide methomyl (11.29%). The application of methomyl at a spraying interval of three days produced the highest fresh weight (155.08 g) compared to other spraying frequencies.

Abstract

The decline in mustard productivity in recent years has been associated with increasing pest pressure and the uncontrolled use of insecticides. This study aimed to evaluate the effects of a neem leaf–based botanical insecticide and the synthetic insecticide methomyl, applied at three spraying frequencies, on total bacteria, total fungi, soil pH, and pesticide residues. The experiment was arranged in a randomized block design with nested treatments and a separate control. The results showed that the control and the treatments did not differ significantly in total bacterial populations, and insecticide type also had no significant effect. Within the nested factor, methomyl applied at a three-day spraying frequency produced the highest total bacterial population and differed significantly from the other treatments. Total fungal populations did not differ significantly across all treatments. Both types of insecticides increased soil pH compared with the control, with a greater increase observed in methomyl; spraying frequencies of six and nine days produced the highest soil pH values. Residue analysis showed that neither neem nor methomyl triggered the accumulation of persistent semi-volatile residues, and the detected chemical traces more closely reflected soil volatilization dynamics rather than the formation of long-term contaminants. Methomyl increased bacterial populations and soil pH as a short-term degradation response, while the botanical insecticide exerted lower ecological pressure due to its rapid degradation and the absence of stable metabolites. These findings confirm the potential of neem as a more sustainable pest management option and provide a scientific basis for determining pesticide application frequencies that are safe for soil conditions.
