Abstract

Limestone mining removes topsoil and produces overburden piles, which is improper for plant growth. The objectives of this study were to compare the texture, certain chemical properties, and bacterial population of overburden to the topsoil and to observe the effects of compost amendment on the growth of corn seedlings on the potted overburden. The overburden characterization was performed using a quantitative descriptive method with purposive sampling. Samples were taken from a 6-month-old overburden pile and a pine-vegetable agroforestry ecosystem. The data were further analyzed by using the Student’s t-test. A bioassay was set up in                            a randomized block design with various concentration compost treatments and five replications. The results showed significant differences between texture, chemical characteristics, and bacterial counts of overburden and topsoil were recorded. The topsoil was more acidic and had higher organic carbon, potential phosphorus, potential potassium, and cation exchange capacity, while the overburden had higher levels of calcium; however, the total N and Magnesium content in topsoil and overburden was similar. The bacterial population of the overburden was lower than in the topsoil. A total of 16 gram-negative and one gram-positive bacteria have been identified from both samples. Applying huge amounts of compost enhanced corn seedlings' growth in the overburden. The study suggested that overburden was more unfertile compared to the topsoil. Therefore, the improvement of overburden properties by compost amendment is needed to green the area.

Abstract

Kopi Arabika Puntang menjadi salah satu produk unggulan pertanian di Desa Campakamulya, Kabupaten Bandung, Jawa Barat. Cita rasa dan aroma yang khas menjadikan kopi ini banyak peminat, namun produktivitas kopi arabika ini terus menurun. Pengabdian pada masyarakat (PPM) ini berupaya mendongkrak produksi kopi Arabika Puntang di Lembaga Masyarakat Desa Hutan (LMDH) Bukit Amanah di Desa Campakamulya, Kabupaten Bandung, Jawa Barat. Produktivitas kopi yang rendah di wilayah ini disebabkan oleh kondisi fisik lingkungan dan tanah yang kurang baik. Selain itu, setidaknya terdapat 17 spesies nematoda parasit yang berbeda ditemukan di tanah perkebunan kopi dengan tegakkan hutan pinus, yang dapat menyebabkan pertumbuhan terhambat, pematangan buah tidak merata, dan hasil panen rendah. Untuk mengatasi masalah tersebut, PPM ini mengusulkan beberapa solusi yaitu perbaikan kesuburan tanah melalui pemupukan berimbang, pengendalian hama dan penyakit, dan praktik konservasi tanah. Seminar dan lokakarya dengan tema "Peningkatan Produktivitas Lahan Perkebunan Kopi Berbasis Karakteristik Tanah dan Lingkungan" juga menjadi bagian dari program PPM ini. Penerapan metode ini diharapkan mampu meningkatkan produksi kopi Arabika Puntang dan membantu memenuhi permintaan dunia akan kopi berkualitas tinggi ini. Petani juga mendapat manfaat dari program ini, karena meningkatkan pemahaman mereka tentang tingkat kesuburan tanah dan cara menjaga kesuburan tanah.

Abstract

Lithologic discontinuity reflects the distinct change between different types of soil layers that can occur due to various geological process, resulted in variation composition, colour, texture, organic matter, consistency, structure, and others characteristics. Soils derived from volcanic eruption have the possibility to have lithologic discontinuity in the depth of the soil profiles due to the different eruption that formed the soils. Soils developed from the eruption of Mt. Patuha were investigated whether lithologic discontinuity presence the soil layers. The research used descriptive and comparative method of two profiles, analysed the soil macro-morphology and soil laboratory analyses covered colour, organic carbon, texture, consistency and structure. The result showed that the unusual pattern distributed of colour, organic matter, consistency, structure indicated the lithologic discontinuities of the underlying 2Ab (A buried) horizon to the overlying horizon. The darker colour, higher organic matter content, friable consistency in 2Ab in deeper depth, were some indications of lithologic discontinuities, where in soil without lithologic discontinuities the deeper depth or horizon was normally lighter colour, lower organic matter content and firmer consistency. However, detailed analysed with instruments like XRF and VIS DRS are needed to have the precise elemental composition in every horizon which conclude the horizon from the same or different parent materials.

Abstract

The Cikapundung Sub-watershed is part of the Upper Citarum Watershed, with its catchment area covering West Bandung Regency, Bandung City, and Bandung Regency. The increasing land use activities in the Cikapundung Sub-watershed have driven significant development activities in the upper areas of the subwatershed. One of the factors influencing this development is the road network, which affects the accessibility of an area, known as the driver variable. The creation of this driver variable requires GIS analysis using the Euclidean distance module, which calculates the distance from the roads. This calculation yields radial distances, ranging from the farthest to the nearest distances. It is known that local roads are the longest in the Cikapundung Sub-watershed, reaching 644.31 km. Based on the Euclidean distance calculation, the farthest distance from the road is 9504.22 meters, and the nearest is 0 meters. The map resulting from this calculation can be used to analyze the extent to which the distance from the road influences land use changes as a driver variable in the Cikapundung Sub-watershed.

Abstract

Nitrogen-fixer and phosphate-solubilizer bacteria increase the chemical-fertilizer efficiency and soil health. Bacterial-coated NPK fertilizer is a novel approach for intensifying biofertilizer application in vegetable production. The study aimed to observe the compatibility between two Azotobacter species and two Bacillus species, their population on two formulations of bacterial-coated NPK fertilizer (BCN), and the effect of BCN dose on growth, N and P content, and their uptake in tomato shoots. The compatibility test was performed using the streak method. The population of Azotobacter and Bacillus were counted for two formulations of NPK fertilizer coated by solid biofertilizer (5% and 10%) and zeolite (1% and 5%). The pot experiment was conducted in a randomized block design with four treatments and six replications. The treatments were 100% recommended doses of conventional NPK fertilizer (700 kg/ha) and 100%, 80%, and 60% doses of BCN. The results showed four bacterial species were compatible, indicated by synergistic growth on the plate agar. The BCN formula using 5% liquid inoculant and 5% zeolite has higher cell viability. The BCN enhanced stem thickness and leaves number but did not change the plant height, dry weight, N and P content, and their uptake in shoots. Applying 60% of BCN caused greater stem thickness and leaf number. Despite being insignificantly different from another treatment, that dose increased the biomass and the shoot uptake of N and P. The NPK fertilizer coated by Azotobacter and Bacillus has the potency to increase tomato growth and NPK fertilizer dose.
