Abstract

Kabupaten Sijunjung, Sumatera Barat, memiliki cadangan emas yang diperkirakan ada di beberapa lokasi. Kegiatan penambangan umumnya dilakukan di lahan pertanian dan perkebunan seperti persawahan dan perkebunan karet dengan teknik penambangan terbuka yang berpotensi merusak lingkungan. Akibat pengerukan, penimbunan, dan pemadatan kendaraan berat merusak tekstur tanah, pada tata air, resapan air yang terganggu akan meningkatkan limpasan dan erosi. Strategi perbaikan sifat fisik tanah dilakukan dengan penanaman tanaman penutup tanah yang dikenal dengan Legum Cover Crop (LCC). Tanaman ini dapat hidup dan bertahan hidup di tanah yang rusak dan berguna untuk melindungi tanah dari kerusakan erosi dan menghasilkan bahan organik dalam jumlah besar. Penelitian ini bertujuan untuk memperbaiki sifat fisik lahan bekas penambangan emas. Penelitian ini dilakukan di Nagari Pala Luar Kecamatan Koto Tujuh Kabupaten Sijunjung Sumatera Barat selama 3 bulan dan dilakukan analisis tanah di Laboratorium Tanah Fakultas Pertanian Universitas Andalas. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 5 perlakuan LCC yang berbeda: A = Kontrol (tanpa penerapan LCC), B = Mucuna conchinchinensis, C = Calopogonium mucunoide, D = Centrocema pubescens dan E = Mucuna bracteata. Data yang terkumpul dianalisis menggunakan Analisis Varians (ANOVA) dan uji Tukey's HSD diterapkan jika ada perbedaan rata-rata. Hasil penelitian menunjukkan bahwa penggunaan LCC Mucuna conchinchinensis telah memperbaiki sifat fisik tanah yang ditunjukkan dengan peningkatan bahan organik tanah, penurunan volume tanah (BV), dan peningkatan total pori-pori tanah bekas tambang emas di Sijunjung.

Abstract

The percentage of slope classes on a land has an impact on changes in soil physics. The purpose of this study is to evaluate the physical properties of soil planted with tobacco on various slopes in Kenagarian Situjuah Batua, Situjuah Limo Nagari District, Lima Puluh Kota Regency. The method used in this study was a survey; samples were taken purposively based on slope classes at slopes 8-15%, 15–25%, and 25–45% at depths of 0–20 cm and 20–40 cm. From each slope 3 repetitions were taken. The results showed that there were changes in soil physics properties in each slope class with the dominant texture of sandy clay loam. Organic matter was classified as high to low (18.77–3.63%), low soil buld density (0.66–0.34 g/cm3), and total pore space was classified as high (75.27–86.87%). The permeability of the soil was classified as very fast to somewhat slow (34.88–0.78 cm/h), and the aggregate stability index was somewhat steady to less steady (60.89–45.98%). It is recommended that tobacco farmers to make terrracing and cut the length of the slope so that it does not lose organic matter. Keywords: soil physical properties, slope level, tobacco plantation

Abstract

This study investigates the impact of decanter solid and arbuscular mycorrhiza on the growth of oil palm seedlings in pre-nursery on ex-iron ore mining sites. The construction of pits during iron mining has resulted in soil degradation and abandonment. The addition of solid decanter and arbuscular mycorrhiza can improve the chemical characteristics of soil. The study sought to determine the interaction between solid decanter and arbuscular mycorrhiza, as well as the optimal dose of solid decanter and arbuscular mycorrhiza for oil palm seedling growth in the pre-nursery. This study employed a factorial Completely Randomized Design with two factors and four treatment levels. The first factor was solid decanter (0, 200, 300, and 450 g), whereas the second was arbuscular mycorrhiza (0, 5, 10, and 15 g/polybag). The parameter studied included initial soil analysis, solid decanter analysis, final soil analysis, seed height, stem diameter, number of leaves, leaf length, fresh and dry seedling weights. The study's findings revealed an interaction between solid decanters and arbuscular mycorrhiza on leaf length, fresh weight, and dry weight of seedlings. The treatment dose of 450 g solid decanter and 5 g/polybag arbuscular mycorrhizae resulted in the best growth in all variables. Keywords: arbuscular mycorrhizae, fertility, mycorrhiza, pre-nursery

Abstract

Gold mining is an activity that utilizes natural resources by extracting the economic value of the deposits. Mining activities can produce hazardous pollutants, namely Hg (mercury), which can physically, biologically, or chemically damage soil quality. This study aimed to determine the role of biokanat application on the chemical properties of ex-mining land and to determine the effect of biokanat on reducing Hg levels in Kanagarian Padang Sibusuak, Sijunjung Regency. This study was a field experiment with 3 biokanat treatments (0, 10, and 20 ton/ha) with 3 replicates. The experimental 9 units were allocated based on Randomised Block Design. The data were statistically analyzed using an F-test with a 5% significance level. Then, it was continued using DNMRT if the Fcalculated > Ftable. The results showed that the dose of biokanat 20 ton/ha could increase the soil pH to 6.08, organic-C to 2.4%, P-available to 11.96 ppm, total-N to 0.23%, CEC to 2.58 cmol/kg, the basic cations especially Ca into 3.53 cmol/kg, Mg into 0.37 cmol/kg, K into 0.26 cmol/kg, and Na into 0.29 cmol/kg. Application of biokanat 20 ton/ha reduced the soil mercury (Hg) content to 15.96 ppm. Keywords: biocanat, mercury, gold mining

Abstract

High acidity levels and low availability of alkaline elements such as Ca, Mg, and K inhibit plant growth and reduce land productivity. This study examined the effect of dolomite and fly ash doses on the chemical properties of peatland. This study used a 2 × 3 factorial randomized block design (RBD) with three replicates. The first factor was the type of soil conditioner, namely dolomite and fly ash. The second factor was the soil conditioner dose, namely 5, 10, and 15 t ha-1. The type of soil ameliorant did not interact significantly with the dose of soil conditioner for pH, water content, organic C, total N, K, P, Fe, Cu, Zn, Mg, Ca, K-exch, and humate. Dolomite was superior in increasing base elements (Ca, Mg, and K) and the humification process of organic matter, while fly ash played an important role in increasing microelements (Fe, Cu, Zn) and carbon stabilization. Meanwhile, an ameliorant dose of 15 t ha-1 significantly increases pH, moisture content, organic carbon, and macronutrients (P and K). Dolomite and fly ash at an optimal dose of 15 t ha-1 are recommended as a sustainable amelioration strategy to increase pH, chemical fertility, and carbon stability in peat soils without causing negative environmental impacts.

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.
