Abstract

Rice (Oryza sativa) production in Indonesia has declined due to low iron (Fe) availability in alkaline soils, impacting plant growth and yield. Integrating Fe seed coating with sago (Metroxylon sp.) waste organic fertilizer may improve Fe availability and soil quality, offering a potential solution to enhance rice production. Our objective was to examine the effects of Fe seed coating and the incubation of sage waste organic fertilizer on rice growth. The study employed a factorial 2-factor randomized block design. The first factor was the concentration of Fe seed coating, with four levels: 0 g, 55 g with 2.5 g gypsum, 110 g with 5 g gypsum, and 275 g with 12.5 g gypsum. The second factor was the incubation time of organic fertilizer, with four durations: 0 weeks, 3 weeks, 4 weeks, and 5 weeks. The interaction between Fe seed coating and sago waste organic fertilizer incubation significantly impacted plant height (153.33 cm), leaf color chart scale (4), chlorophyll a (254.73 μmol.m-2), chlorophyll b (96.90 μmol.m-2), with the most notable effects observed at a Fe seed coating concentration of 275 g with 12.5 g of gypsum and a 5-week incubation period. The application of Fe seed coating at a concentration of 275 g with 12.5 gypsum, combined with a 5-week of sago waste organic fertilizer, effectively enhances plant height, chlorophyll a, chlorophyll b, and the leaf color chart scales.

Abstract

Lahan yang sesuai untuk usaha pertanian adalah lahan yang mempunyai kecocokan antara potensi lahandengan syarat tumbuh optimal suatu jenis tanaman pertanian. Penelitian ini dilakukan untuk menentukandan memetakan kelas kesesuaian lahan sayur-sayuran (hortikultura) khususnya tanaman kentang, tomat,dan kubis di Desa Tonasa Kecamatan Tombolo Pao. Penelitian ini menggunakan metode kualitatifdengan menggunakan pendekatan faktor pembatas sederhana. Pengambilan sampel dilakukan secarapurposive sampling berdasarkan peta unit lahan yang terdiri dari empat unit lahan, pada sistem lahan Barong Tongkok (BTK) dan Tanggamus (TGM). Kriteria kesesuaian lahan yang digunakan adalah kriteria menurut Djaenuddin et al. (2011). Penelitian ini menunjukkan bahwa kelas kesesuaian lahan aktual di lokasi penelitian untuk tanaman kentang tergolong sesuai marginal (S3) seluas 2.037 Ha (100%) dengan faktor pembatas retensi hara yaitu pH. Untuk tanaman tomat sebagian tergolong cukup sesuai (S2) seluas 1.778 Ha (87,29%) dengan faktor pembatas ketersediaan air yaitu curah hujan dan kelembaban; retensi hara yaitu kejenuhan basa dan pH; bahaya erosi yaitu lereng serta sebagian tergolong S3 seluas 259 Ha (12,71%) dengan faktor pembatas retensi hara yaitu pH. Untuk tanaman kubis tergolong S3 seluas 2.037 Ha (100 %) dengan faktor pembatas retensi hara yaitu kejenuhan basa dan pH. Desa Tonasa Kecamatan Tombolo Pao memiliki potensi untuk pengembangan tanaman hortikultura yang ditunjukkan dengan hasil analisis kesesuaian lahan aktual untuk tanaman kentang (S3), tomat (S2 dan S3), dan kubis (S3). Kelas kesesuaian lahan potensial tergolong S2 untuk tanaman kentang, tomat, dan kubis dengan faktor pembatas kelembaban.

Abstract

Using biological agent microorganisms such as Arbuscular Vesicular Mycorrhiza (AVM) is needed to improve post-mining soil fertility. This research aimed to explore and identify morpho species of AVM in the post-nickel mining areas Soil samples were taken from the tree rhizosphere at each representative point. The soil samples have been isolated using Brundrett's method of wet sieving and decanting; AVM spore density is determined for each 20 g soil sample; and spores are grouped based on morphological traits up to the morphogenic stage of the species. The results showed that there are four mycorrhizal species found in the rhizosphere of plants in the nickel post-mining soil of PT Vale Indonesia Tbk., namely Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp. Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp obtained 18, 8, 8, and 7 morpho species, respectively. The highest spore density is 34 spores of Gigaspora sp4 found in the rhizosphere of Casuarina rumphiana, 57 spores of Acaulospora sp1 in the rhizosphere of Macaranga gigantea, two spores of Glomus sp1, sp2, and sp6 each as many as two spores per 20 g of soil in rhizosphere of Enterolobium cyclocarpum, Dillenia serrata, Maesopsis eminii, 11 spores of Scutellospora sp6 in the Shizigium sp rhizosphere. One finding revealed that Gigaspora and Acaulospora predominated in the rhizosphere over other mycorrhizas. The results of this AVM identification will be the basis for the mass propagation of local AVM for broader use in the post-nickel mining land area in Sorowako. Widespread use of AVM is a form of post-nickel mining land management based on local resource potential, particularly the dominant trees rhizosphere and the most commonly found AVM types. This proves that AVM can colonize plant roots in this nickel post-mining soil and potentially be mass-propagated, especially species.

Abstract

It is estimated that hundreds of millions of tonnes of carbon stored in soil have been lost due to human activities, primarily through soil cultivation practices and land cover changes. The organic C content in the soil varies, depending on the climate, soil type, mineralogy, land cover and management. The existence of the C-organic distribution map can be a reference in dealing with existing problems, especially in the agricultural sector regarding soil fertility in the region. This study aims to determine the level of soil organic carbon in several types of land cover and slope classes to map the spatial distribution of soil organic carbon in several land covers and slope classes in Simbang District, Maros Regency. Soil sampling was carried out using a drill at a depth of 0-15 cm, for each point a sample was taken. Soil analysis includes c-organic, soil texture, soil color, and bulk density. Making maps of the distribution of soil organic carbon using ArcGIS spatial analysis with interpolation techniques. The highest soil C-organic content was obtained in secondary forest land cover with slopes of 0-8% (flat) with a bulk density value of 1.05 g/cm3 and a color of 7.5YR 3/3 dark brown. The lowest C-organic content was obtained in scrub land cover with a slope of 8-15%, namely 1.21% with a bulk density value of 1.50 g/cm3 and a color of 5YR 4/4 reddish brown. In addition, the soil texture results also showed that the highest clay fraction content was found in secondary forest land covers and slopes of 0-8%. Land cover and slope gradient affect the C-organic content. The highest C-organic content was obtained in secondary forest land cover with a flat slope with an area of 249.92 ha. While the lowest C-organic content was obtained in shrub land cover with a gentle slope with an area of 59.75 ha. The distribution of soil organic carbon content in Simbang District is dominated by the moderate category.

Abstract

Technological developments in the agricultural sector are currently increasing for maximum production results. This encourages the use of chemicals or inorganic materials as nutrients for plants, especially mustard greens. Biosaka is a new form of innovation that is suitable for development because the basic materials used come from organic materials or green plants. This biosaka acts as an elicitor, not a fertilizer. This research aims to determine the effect of Biosaka and Gamal Leaves on the growth of mustard greens and is expected to reduce the use of chemicals. This research is divided into five main stages, namely: 1) Making Biosaka; 2) Incubation of Gamal Leaves; 3) Planting and maintaining mustard plants; 4) Application of Biosaka; and 5) Analyze and process data using a Completely Randomized Design (CRD) with 10 levels of treatment combinations (biosaka 4 levels of treatment and gamal leaves 3 levels of treatment). In the parameters of plant height, number of leaves, pH, C-Organic, and N-total, the K2G1 treatment (3 ml of biosaka + 2 liters of H2O + 25 grams of gamal leaves) was the treatment with the best results. Meanwhile, for the parameters of fresh weight, leaf length and Cation Exchange Capacity (CEC), the K3G2 treatment (4.5 ml of biosaka + 2 liters of H2O + 50 grams of gamal leaves) showed the best treatment. The K3G2 treatment was the treatment with the best results with a value of 35.67 grams with a percentage increase of 2.32% from the control treatment. Based on the results of research on the application of Biosaka and Gamal Leaves, it shows a very real influence in the interaction test of the two factors, which means there is an influence on the plants after being treated.
