Abstract

MOL is fermented solution by microbes from organic ingredients such as banana peel. MOL are useful in accelerating the destruction of organic materials and can be used as organic containing NPK fertilizer . This study aims to know the effect of the mixed of rice washing water and banana peel as MOL solution to the growth of pakcoy plants (Brassica rapa chinensis) and the its best concentration. The research design used in this study was a completely randomized design (RAL) consisting of 5 treatments and 5 replications. The treatments in this study were P0 (control) P1 (10%) P2 (20%) P3 (30%) and P4 (40%). The data were analyzed using analysis of variance (ANOVA) and continued with the Duncan/DMRT test (Duncan Multipe Range Test) at a significance level of 5%. The results showed that the MOL of kepok banana peel affects the growth of pakcoy plants on certain parameters, namely wet weight, dry weight and plant root length but not for the height and number of leaves. P2 treatment(20%) showed the best results.

Abstract

This research aims is to find starter for sorghum fermentation and to observe its influence in fermentation process and tannin level in sorghum flour. Four isolates of Lactic Acid Bacteria were tested as starter for Numbu and Kawali sorghum grain fermentation. The criteria was the ability to produce acid and cell viability. The fermentation used four treatments in duplicates. The selected isolate was inoculated into dehulled and non-dehulled sorghum grain. The fermentation time were 0, 24, and 48 h. Analysis were pH, total acidity, total sugar, viable cell, tannin level, structure of sorghum flour, the yield of flour passed 80 mesh, and flour moisture. The results showed that E1222 was selected as a starter for Numbu sorghum grain fermentation while E5 was selected for Kawali. The starter can decrease pH value, increasing total acidity, decreasing total sugar, however there was no significant difference in viable cell in fermentation process. It decreased tannin level approximately 90% in Numbu fermented flour and 77% in Kawali. There was corrosion in starch structure of fermented flour, while the yield of flour passing through 80 mesh was increased. The best treatment was fermentation of dehulled and inoculated sorghum grain (So-St) in both of sorghum varieties.

Abstract

Tomatoes are the popular fruit but having short shelf life. This fruit require some treatment to maintain it’s quality during post-harvesting. Eco-enzyme is a fermented liquid, it’s made by fermentation process of fresh waste vegetables or fruits. Previous study showed that spraying tomatoes with Eco-enzyme can maintain the shelf life of tomatoes. This study aim to observe the effect of various liquid in Eco-enzyme fermentation and it’s effect to tomatoes preservation by soaking method. The research was experiment research using quality scale of tomatoes. The Eco-enzyme was fermented using different liquid such as water, coconut water and rice rinsed water. Tomatoes were soaked with each Eco-enzyme treatment with 50% and 100% concentration of each liquid for 5 minutes then rinsed them and observed their quality for 8 days during storage process. The control treatments are non-soaked and non-rinsed tomatoes. The observation include the quality of tomatoes and the quality of Eco-enzyme. The result of this study found that modification of liquid in Eco-enzyme fermentation have different effect for tomatoes preservation. Soaking and rinsing method also have different effect for tomatoes. The best treatment for EE1 is EE1-rinse-concentration 50%, EE2 is EE2-rinse-concentration 100%, and EE3 is EE3-rinse-concentration 50%. The soaking followed rinsing was the best method for tomatoes preservation treatment using Eco-enzyme.

Abstract

Macrozoobenthos are effective bioindicators for assessing freshwater ecosystem health. This study examines the influence of physicochemical parameters and spatial-temporal variation on macrozoobenthic abundance in the Kungkilan River, South Sumatera. Sampling was conducted at upstream, midstream, and downstream sites. Generalized Linear Mixed Model (GLMM) analysis revealed that water depth and transparency had significant positive effects, while iron (Fe) in sediment had a negative effect. Random effects analysis showed that site-level variability (variance = 0.680) was far greater than temporal variability, indicating that spatial differences—especially in the midstream zone—were the dominant drivers of community structure. These findings highlight the importance of localized conservation efforts and reinforce the role of macrozoobenthos as reliable indicators of river health in tropical ecosystems.

Abstract

The impact of coal mining pollution on rice fields located near mining areas can affect the health of communities that consume the harvested rice. Ants can serve as bioindicators of environmental pollution. This study aims to investigate the diversity of ants in rice fields located near and far from coal mining areas. The results show differences in ant diversity between rice fields near and far from the coal mining site. Ant species found in the rice field near the mining area included Leptogenys chamela (44 individuals), Solenopsis invicta (4 individuals), and Camponotus texanus (8 individuals). In contrast, in the rice field farther from the mining area, seven species were found: Solenopsis invicta (5 individuals), Myopias emeryi (71 individuals), Tetraponera rufonigra (37 individuals), Paraponera clavata (7 individuals), Leptogenys chamela (5 individuals), Dolichoderus sp. (1 individual), and Camponotus texanus (13 individuals). Ant abundance was higher in the rice field located farther from the coal mining area compared to the one located nearby.

Abstract

A micro-mushroom namely Sphaerobolus stellatus (BO 24422) and macro-mushroom namely Trichaleurina javanica (BO 24420) were found in Landscape Arboretum of IPB University. The latest identification used morphological characteristic and molecular study of Large Subunit DNA marker respectively. According to their identification, the database of fungal identification is commonly from Internal Transcribed Spacer (ITS) marker for molecular study. But both specimens, S. stellatus BO 24422 and T. javanica BO 24420, have not the ITS sequences yet. This research aim to study the molecular data of two specimens using ITS sequences. The method of this research used the molecular identification using internal transcribed spacer (ITS) primer: ITS 4 as a forward and ITS 5 as a reverse. Two phylogenetic trees were generated by Randomized Axelarated Maximum Likelihood (RAxML) Black box. Bootstrap (BS) values ≥ 90% were displayed on the phylogenetic treebranches. The result showed that the bootstrap value for S. stellatus BO 24422  showed the good value as 96% classified as S. stellatus. Then, T. javanica BO 24420  had a better BS value with 93% classified as T. javanica. The ITS is a general marker and very useful for molecular identification.
