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

Small-scale gold ore processing areas have become a global concern due to their significant contribution to heavy metal pollution. The residual amalgamation process in these areas leads to the accumulation of heavy metals in the environment, which can bioaccumulate in living organisms. This study focuses on the lime plant (Citrus aurantifolia), commonly found in small-scale gold ore processing areas, particularly in Sukamenang village. The research aims to assess the Bioconcentration Factor (BCF) and Estimated Daily Intake (EDI) of heavy metals in lime plants to evaluate the risk to residents who consume them. Samples were collected using random sampling and analyzed with an Atomic Absorption Spectrophotometer (AAS) and a mercury analyzer. The results indicate that Citrus aurantifolia has a BCF value of less than 1 (<1), classifying it as an excluder plant, effectively preventing heavy metals from entering its upper parts and allowing it to thrive in polluted environments. However, the consumption of these plants poses health risks. The study highlights the Reference Dose (RfD) values for heavy metals: Cu at 4.0 x 10^-2 (0.008), Fe at 0.7, and Hg at 0.0001, as recommended by the United States Environmental Protection Agency (USEPA) in 2011. Heavy metals such as Fe, Cu, and Hg in the lime plants indicate potential adverse health effects due to their toxicity. This research underscores the necessity for monitoring and mitigating heavy metal pollution in small-scale gold ore processing areas to protect public health and the environment.

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

This study aims to determine the diversity of phytoplankton in the river in Banyuasin Regency. Phytoplankton samples were taken using an active sampling method using a plankton net in an upright position on the water surface. The results of the study obtained five classes consisting of 32 species of phytoplankton. The highest abundance was at station II in the morning as many as 684 individuals/l and the lowest abundance was at station I in the morning with an abundance of 286 individuals/l. The most dominant diversity was found in Planktothrix sp species and when viewed from the abundance value the most dominant species were Phacus cloroplate, Trachelomonas lacustris, Diatoma elongatum, Ankistrodesmus falcatus, and Pediastrum tetras species. The results of the analysis show that the abundance of a phytoplankton has a close relationship with the physico-chemical parameters in a waters.AbstrakPenelitian ini bertujuan untuk untuk mengetahui keanekaragaman fitoplankton di Sungai di Kabupaten Banyuasin. Pengambilan sampel fitoplankton menggunakan metode sampling aktif menggunakan plankton net dengan posisi tegak lurus pada permukaan air. Hasil penelitian diperoleh lima kelas yang terdiri dari 32 spesies fitoplankton. Kelimpahan tertinggi terdapat pada stasiun II pagi hari sebanyak 684 Individu/l dan kelimpahan terendah terdapat pada stasiun I pada pagi hari dengan kelimpahan sebanyak 286 individu/l. Keanekaragaman yang paling dominan terdapat pada spesies Planktothrix sp dan jika dilihat dari nilai kelimpahan nya spesies yang paling dominansi terdapat pada spesies Phacus cloroplate, Trachelomonas lacustris, Diatoma elongatum, Ankistrodesmus falcatus, dan Pediastrum tetras. Dari hasil analisis memperlihatkan bahwa  kelimpahan pada suatu fitoplankton memiliki kaitan erat dengan parameter fisika-kimia pada suatu perairan.
