Abstract

Dairy farming waste in high volume especially in the form of flushing slurry can be unmanageable. Flushing slurry is lower in organic matter content compared to solid waste due to water saturation. In order to enhance the utilization, flushing slurry can be converted in liquid organic fertilizer with higher nutrient content. King grass (Pennisetum purphoides L.) plant is commonly used as livestock feed especially dairy cow in South Bandung area. The experiment was conducted between March to June 2018 in Pangalengan, South Bandung. The result shows no significant different between control specimen and liquid organic fertilizer teratments in plant hight, number of leaves, root weight, and root length. Although notable amount of plant leaves was demonstrated in D treatment compared to than that of control.

Abstract

One of the problems on soybean production in North Kalimantan is the acidic soil conditions. The use of soybean varieties that are resistant to acidic soil conditions is an alternative to overcome this problems. Dena 1 and Devon 1 soybeans were the varieties that can be grown in acid soils. In addition to the right seeds, application of fertilizer is also needed to support the growth and grain yield of soybean. This study aimed to determine the interaction between varieties with Urea dosage on growth and grain yield of soybean varieties Dena 1 and Devon 1. The experimental design of this study was factorial randomized block design with two factors. The first factor was the soybean variety which consisted of: V1 = Devon 1 and V2 = Dena 1. The second factor was the Urea fertilizer dosage which consisted of four levels: P0 = Control, P1 = 1.32 g/plant, P2 = 2.64 g/plant, P3 = 5.28 g/plant. The results showed that there were no interaction between varieties and the Urea fertilizer dosage on growth and grain yield of soybeans. However, the variety independently had a significant effect on plant height and leaf width, which was shown by the Dena1 (V2) treatment.

Abstract

Corn is one of the important commodities in Indonesia that is not only used as food but also as livestock feed and industry, as well as alternative fuels (biofuels). Degradation of soil fertility became one of the factors limiting the production of this commodity. The purpose of this study was to determine the effect of innovative phosphate fertilizer on the growth and yield of sweet corn on Inceptisols with low fertility. The research was conducted from September 2018 to January 2019. Randomized Block Design (RBD) was used with treatment arrangements as follows: A = Control (without P), B = Recommended NPK dosage (300 kg / ha urea + 150 kg / ha SP-36 + 50 kg / ha K), C = ¼ P (300 kg / ha N + 25 kg / ha SP-36 Inv + 50 kg / ha K), D = 1/2 P (300 kg / ha N + 50 kg / ha SP36 Inv + 50 kg / ha K), E = ¾ P (300 kg / ha N + 75 kg / ha SP-36 Inv + 50 kg / ha K), F = 1 P (300 kg / ha N + 100 kg / ha SP-36 Inv + 50 kg / ha K), G = 1 ¼ P (300 kg / ha N + 125 kg / ha SP-36 Inv + 50 kg / ha K), H = 1½ P (300 kg / ha N + 50 kg / ha SP-36 Inv + 150 kg / ha K), I = 1 ¾ P (300 kg / ha N + 175 kg / ha SP-36 Inv + 50 kg / ha K), J = 0 (Without NPK). The results showed that the SP-36 innovative inorganic fertilizer that was given together with urea and KCl increased the yield of sweet corn equivalent to the standard yield of corn in NPK fertilizer. The treatment with the highest results is 1½ P doses of SP-36 innovation results and P from standard NPK both of which are equivalent to 150 kg / ha P. The yield of sweet corn yields ranges from 21.16 - 21.56 tons per hectare.

Abstract

This study investigates the microbial populations during different coffee fermentation processes and their impact on coffee quality. Bacillus, Pseudomonas, and endophytic populations in coffee beans undergoing natural saccharic and natural lactic fermentation remained unchanged compared to fresh coffee beans. However, a notable increase in Bacillus population occurred in honey saccharic fermentation, possibly attributed to the high sugar content in the mucilage, supporting bacterial growth. Additionally, the introduction of Lactobacillus and Saccharomyces during fermentation enhanced sugar consumption and influenced the final coffee quality, particularly aroma profile and nutritional composition. Varietal differences were observed, with Bacillus population decreasing slightly post-fermentation, especially in honey saccharic and natural lactic processes. This decline may be attributed to the dominance of Saccharomyces and Lactobacillus, antagonistic to Bacillus, and the fermentation conditions leading to decreased pH, unfavorable for Bacillus. These findings highlight the intricate microbial interactions and their implications for coffee fermentation and quality.

Abstract

These chemical residues affect the natural balance of soil biota, leading to a decrease in soil pH, areduction in Cation Exchange Capacity (CEC), and a general decline in land productivity. If not treatedpromptly, this damage could harm health and food sustainability. The application of eco-friendlyproducts in modifying soil characteristics, including high-quality zeolite, remains common today. Thisstudy aims to examine the effects of zeolite application on the dynamics of soil chemical characteristicsto promote the development of a sustainable agricultural system. This study employed a RandomizedBlock Design (RBD) containing six different treatments such as five varying recommendation dosagesof zeolite (0.5, 1, 1.5, 2, and 2.5) and one control treatment devoid of zeolite for comparative analysis.Each treatment was reproduced three times, yielding a total of eighteen experimental plots. Soilchemical parameters (pH and CEC) are the primary focus of this experiment. The study's resultsindicated that during the last weeks of testing, applying 1.5 to 2 doses of zeolite proved to be the mostbeneficial, as it continuously raised the pH and CEC levels. Both Pearson and Spearman tests indicatethat the correlation between variables improves from first week to week fourth week. This suggeststhat the effects of the treatment, possibly zeolite application or an alternative treatment, start afterseveral weeks. The results of this investigation indicate that incubation time in zeolite applicationimportant for exhibits effective buffering properties and functions efficiently, significantly improvingthe chemical properties in soil.
