The Effect of Composted Oil Palm Empty Bunches on Growth and Yield of Pakchoi Plants in Ultisol Soil
Full text linkUltisol faces several challenges as agricultural land, including high soil acidity, low organic matter content, macro-nutrient deficiencies, and low cation exchange capacity that need to be addressed. One proposed solution is the use of oil palm empty fruit bunch (EFB/TKKS) compost, which is rich in N, K, and organic C. This compost can improve the physical properties and soil structure, making it a potential alternative for amending Ultisol. Pakchoi, a vegetable rich in vitamins and minerals, has broader stems and leaves compared to regular green mustard. It thrives in various conditions, both lowland and highland, and has a substantial market demand. This research aims to assess the impact of EFB/TKKS compost application on the growth and yield of pakchoi in Ultisol and to determine the optimal dosage. The study employs a Completely Randomized Design (CRD) with one factor, consisting of 5 treatments and 4 replications, totaling 20 experimental units. The treatments include t0 = TKKS compost 0 ton ha-1, t1 = TKKS compost 15 ton ha-1, t2 = TKKS compost 20 ton ha-1, t3 = TKKS compost 25 ton ha-1, and t4 = TKKS compost 30 ton ha-1. The results indicate that the application of TKKS compost significantly influences the growth and yield of pakchoi in Ultisol, with the optimal dosage identified at 20 ton ha-1
Economic Valuation of Pesanggrahan Forest in Malang Regency

The results of the study, obtained a decrease in the Coliform MPN and TPC numbers of water samples after treatment. LB100% X.granatum extract produces an effect that is not significantly different from chlorine. In conclusion, mangrove nyirih has the ability as a water disinfectant.  
Review: The Efficacy of Several Agricultural Wastes as Ameliorant for Peat Degraded Soil: The Case of Kalimantan
Full text linkVarious agricultural wastes are used as ameliorants to improve degraded peat soils, with a focus on cases in Kalimantan. Peat soil is one of the potential land resources for agriculture in Indonesia, with an area ranging from 12.59 to 14.90 million ha, spread across Kalimantan, Sumatra, and Papua. However, the use of peat soil for agriculture faces many obstacles, such as low pH, low base saturation, organic acid toxicity, and macro- and micronutrient deficiencies. The use of agricultural waste as an ameliorant to improve degraded peat soil has prospects and opportunities. Agricultural waste is rich in nutrients and, if managed well, can contribute to sustainable agriculture. This review outlines the characteristics and potential of various agricultural wastes, such as animal waste, food processing waste, crop residues, and hazardous agricultural waste. These wastes are abundantly available and cost-effective, making them a valuable resource for increasing soil fertility and crop yields. This review provides insight into the application of agricultural waste as an ameliorant for degraded peat soils in Kalimantan and identifies challenges and opportunities in this context. This information is important in enriching future peatland management strategies in relation to increasing productivity and production of cultivated plants on peatlands

The single factor of application of arbuscular mycorrhizae and SP-36 fertilizer each had a very significant effect on root colonization. Combination of arbuscular mycorrhizae at a dose of 10 g ton - 1 equivalent to 0.2 ton ha- 1 and SP-36 fertilizer at a dose of 3.06 g ton - 1 equivalent to 0.275 ton ha – 1 could increase the growth of butternut squash in the swampy land
Evaluation of the chemical quality of coffee grounds composted by various types of decomposers using a scoring system
Full text linkIn recent years, the amount of coffee consumption by the Indonesian people has increased. As a result, there is an increase in coffee waste in the form of coffee grounds so it has the potential to have a negative impact on the environment. Proper management is needed so that coffee grounds are not wasted and pollute the environment. Composting is one way to convert coffee grounds into organic fertilizer. The provision of decomposers is useful for accelerating the composting process of coffee grounds so that it affects the quality of the compost produced. This study aims to determine the chemical quality of coffee grounds compost using different decomposers based on the Indonesian National Standard (SNI) 19-7030-2004. This research was carried out in the Compost House Department of Agroecotechnology and Soil Laboratory Department of Soil Faculty of Agriculture, Lambung Mangkurat University, Banjarbaru for three months, from June to August 2021. This research uses quantitative methods (laboratory analysis) to determine the chemical quality of coffee grounds compost. The treatments were decomposers, d1 = EM4, d2 = M21, d3 = Beka, and d4 = Petro Gladiator. The results showed that the use of EM4, M21, BeKa, and Petro Gladiator decomposers produced organic C, total N, P2O5, K2O, Ca, Mg, and C/N ratio of coffee grounds compost in accordance with SNI 19-7030-2004, but the pH value of coffee grounds compost treated with EM4, M21, BeKa, and Petro Gladiator decomposers did not meet SNI 19-7030-2004
Removal of Turbidity and Color of Contaminated Drinking Water Sources using Chitosan-Bentonite Composite as Adsorbent
Full text linkThe composites of biopolymer chitosan obtained from the swamp fish scale with bentonite as clay minerals has been characterized by the structural, mechanical, surface functional group and composition properties using scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), X-ray fluorescence (XRF) and X-ray Diffraction (XRD) analysis. The morphology structure obtained by SEM for the original chitosan, bentonite, and its composites showed that the particles are relatively well dispersed in the chitosan matrix. The physicochemical properties of the chitosan-bentonite composites depend significantly on the chemistry of the polymer matrices, the nature of bentonite, their modification, and the preparation methods that showed by SEM, TGA, XRF and XRD analysis. The obtained composite of chitosan bentonite was then applied for treating raw water sources of drinking water in Bilu river, South Kalimantan, during the dry season. The raw water sources contained a high value of turbidity (ca. of 370±30 NTU) and color (1300±150 Pt-Co). Batch experiment using the composite of chitosan bentonite for treating raw water sources was significant to reduce the value of turbidity, and the color becomes 24.8±2 NTU and 86.7±5 Pt-Co, respectively. The results then compare to the treatment using the commercial chitosan and bentonite self. Moreover, it found that the raw water treatment using the composite of chitosan-bentonite is more favorable than chitosan and bentonite materials
