Abstract

Soil properties play essential roles in transmitting and holding precipitation water; therefore, they determine the amount of plant-available water in the soil profile. The study aimed to compare the size distributions of Andept soil pores following four-year applications of vermicompost and liquid organic fertilizer (LOF). The experiment was done from 2016 to 2019. The five doses of vermicompost (5, 10, 15, 20, and 25 Mg ha-1) set as the main factor, supplemented with 0 and 100 percent concentrations of LOF as a sub-factor, were arranged in a split-plot design with three replicates. Results showed that adding LOF decreased slow-drainage pores significantly when combined with 10 Mg ha-1 of vermicompost. However, the pore changes by LOF were not significant when applied to other doses of vermicompost. Applying vermicompost and LOF lowered the slow-drainage pores by increasing soil organic carbon and reducing soil particle density. The findings suggest that vermicompost and LOF act as soil ameliorants to reduce water loss by drainage from soil profiles. The study highlights the importance of soil properties in determining plant-available water in the soil profile.

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh perlakuan dolomit dan NPK terhadap sifat kimia baglog, pertumbuhan dan hasil jamur tiram putih (Pleurotuss ostreatus), serta potensi pemanfaatan limbah baglog sebagai bahan pupuk organik. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan lima perlakuan : kontrol (A0), NPK 5,6 g/baglog (A1), NPK 11,2 g/baglog (A2), dolomit 5,6 g/baglog (A3) dan dolomit 11,2 g/baglog (A4), masing-masing diulang tiga kali. Parameter yang diamati meliputi kandungan C-organik, N-total, rasio C/N, P-total, K-total, pertumbuhan morfologi tubuh buah (lebar tudung, tebal tudung dan panjang batang), berat segar jamur, jumlah jamur per rumpun, berat baglog pasca panen dan rasio efisiensi biologis (REB). Hasil penelitian menunjukkan bahwa pemberian NPK dan dolomit berpengaruh nyata terhadap kandungan C-organik, N-total, C/N, P-total dan K-total media. Perlakuan A2 menghasilkan kadar N, P dan K tertinggi, sedangkan kadar C-organik tertinggi diperoleh pada perlakuan kontrol (A0). Namun, perlakuan NPK dan dolomit tidak berpengaruh nyata terhadap pertumbuhan morfologi maupun hasil jamur. Perlakuan dolomit dosis tinggi (A4) cenderung meningkatkan berat jamur, tetapi menurunkan REB. Limbah baglog dari perlakuan NPK (A2) memiliki kualitas kimia lebih baik untuk digunakan sebagai bahan pupuk organik. Hasil ini mengindikasikan bahwa suplementasi NPK dosis 11,2 g/baglog direkomendasikan untuk meningkatkan kualitas limbah baglog, meskipun tidak meningkatkan produktivitas jamur secara siginifikan.

Abstract

Penelitian ini bertujuan membandingkan pengaruh campuran kulit kopi dan serbuk kayu sebagai media tanam terhadap pertumbuhan, produktivitas jamur tiram (Pleurotus ostreatus) dan kandungan unsur hara makro baglog. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan komposisi media (P1: 100% kulit kopi, P2: 75% kulit kopi + 25% serbuk kayu, P3: 50% kulit kopi + 50% serbuk kayu, P4: 25% kulit kopi + 75% serbuk kayu, P5: 100% serbuk kayu) dan masing-masing di ulang tiga kali. Variabel yang diamati meliputi kandungan C-organik, N-total, Rasio C/N, P-total, K-total awal dan akhir media, lebar dan tebal tudung, panjang tangkai, berat jamur, jumlah jamur per rumpun, berat jamur+baglog, berat baglog pasca panen dan nilai REB. Hasil analisis ragam menunjukkan bahwa perbedaan komposisi media berpengaruh nyata terhadap seluruh variabel pengamatan. Perlakuan P3 menghasilkan jumlah jamur per rumpun dan nilai REB tertinggi (98,58%), sedangkan P5 memberikan bobot panen terbesar (121,33 g) dan lebar tudung terbesar. Kombinasi kulit kopi dan serbuk kayu pada perbandingan 50:50 menghasilkan keseimbangan rasio C/N dan ketersediaan unsur hara yang mendukung pertumbuhan optimal jamur tiram. Penelitian ini merekomendasikan pemanfaatan kulit kopi hingga 50% sebagai media tanam alternatif yang berkelanjutan, sekaligus mengurangi limbah pertanian dan meningkatkan efisiensi produksi jamur tiram.

Abstract

Indonesia is an agrarian country and requires the development of improvements in soil productivity. The decline in soil productivity for agriculture is currently caused by several factors, namely land conversion to a decrease in the quantity of ground water. The actual frequency pattern of irrigation water needs with the application of dielectric sensor technology is carried out in cultivation in order to create efficiency in the provision of irrigation water. This research was conducted using a single factor experimental method with repeated measurements on three types of land use, namely land without vegetation, soil with grass vegetation, and soil with tomato cultivation. Measurements were carried out using an automated application of soil moisture monitoring based on dielectric technology with two measuring periods. Each measuring period consists of two weeks or fourteen days. Soil sample analysis was carried out at the Bengkulu University soil laboratory. The results of the observations were analyzed using variance (ANOVA) on the 5% F test table, the BNT test was carried out at the 5% level on data that had a significant effect. The results showed that the frequency of giving irrigation water on the 1st day to the 14th day in the 2 observation periods on the Bera land was the most common compared to the use of grass vegetated land and the use of tomato cultivation land, which was 5 times in the 1st and 4th periods. times in the 2nd period with 14 days each. Provision of irrigation water will stop automatically when the dielectrometer shows the field capacity so that it can show the frequency of giving different water to each field.Key words : Dielectric; Frequency; Irrigation water

Abstract

Entisols are sandy soils with P and K in form still fresh and cannot be absorbed by plants, thereby affecting plant growth and production. Therefore, it is necessary to add rice husk biochar and arbuscular mycorrhizal fungi (AMF) to help provide nutrients to support the growth of sweet corn plants. The research was carried out from August to October 2020 in Beringin Raya Village, Bengkulu City with coordinates S03°45,434' E102°15,687'. The study used a completely randomized design (CRD) with two factors. The first factor was the dose of rice husk biochar: 0, 5, and 10 tons ha-1 ; and the second factor was the AMF dose of 0, 5, and 10 g of propagule. The total 27 units was obtained from nine treatment combinations that was repeated three times. Each experimental unit consisted of 2 sample plants so that there were 54 polybags. Soil parameters observations were soil pH, CEC, organic C, nutrient levels of N, P, K and P uptake. Phosphor uptake was calculated based on the total dry weight of plants x nutrient content of P. The variables observed in plants were plant height, root length, plant dry weight (roots and stems), ear length, cob diameter, cob weight. The result was no interaction between rice husk biochar and AMF on growth, P uptake, and yield of sweet corn. Application 10 tons ha-1 of rice husk biochar of biochar and inoculation of 10 g of plant propagule-1 gave the best results on growth, P uptake, and yield of sweet corn.Keywords: Biochar: Entisols, Mycorrhizal

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

The practice of intensive rice field cultivation and excessive chemical fertilizer use often leads to gradual declines in soil quality and fertility, as well as environmental pollution. By employing Tetadi as an ameliorant technology and adopting SRI cultivation techniques, we can mitigate the adverse effects on rice fields. This study aimed to examine the effects of Tetadi soil ameliorant on the physical properties of paddy soil, growth, and rice yield using the SRI method. The experiments were conducted in paddy fields in Pasar Ambacang, Kuranji, Padang city. Tetadi soil ameliorant was applied at A=0, B=5, C=10, D=15, and E=20 t ha-1. Data on soil physical properties and plants were statistically analysed using ANOVA. The results showed that the change has an insignificant impact on soil physical properties, yet decreases BD (Bulk Density) by 28.2%; increases SOM (Soil Organic Matter) by 18.55%; TPS (Total Pore Space) by 13.7%, moisture content by 5.6%, permeability by 34.2%, and Available Water Pores (AWT) by 20%—application of 20 Mg ha-1. Tetadi increased the number of productive saplings by 52.65% and yield by 69.46% compared to the treatment without Tetadi application.
