Published: April 2021

Small-scale farmers in Tlogosari, Pagak, Malang have many limitations, especially economically. Instead of wanting to improve economic prosperity, small-scale farmer makes changes to the commodities they grow from sugar cane to sengon (Paraserianthes falcataria (L) or albizia). But the change in this commodity has an impact on changing the pattern of short to long harvests. This condition has increasingly resulted in the economic downturn of the farming family, coupled with the existence of the COVID-19 pandemic, making farmers increasingly powerless. This research focuses on the survival mechanism of small-scale farmers who switch commodities from sugar cane to sengon during the COVID-19 pandemic. This study uses James Scott's theory of the ethics of subsistence as a knife of analysis and uses a qualitative approach with a case study method. The research informants were determined by purposive sampling with the criteria of small-scale farmer informants who were affected by the COVID-19 pandemic due to the change of sugarcane commodity to sengon. The price of sengon during the COVID-19 pandemic dropped dramatically due to many factories closed, so farmers are also confused looking for sengon buyers. This condition makes small-scale farmers feel like poor famine. Faced with such conditions, smallholders do survival by other work, namely making gatot, tiwul, and corn grits (ampok) as a profitable employment opportunity in the future of COVID-19

Abstract
This paper presents a study to assess the roof-harvested rainwater (RHRW) in the Ikorodu area of Lagos state, Nigeria, and recommends guidance to minimise the health risk for its households. The types, design and use of rainwater harvesting systems have been evaluated in the study area to inspect the human risk of exposure to Escherichia coli (E. coli). To achieve these objectives, a detailed survey involving 125 households has been conducted which showed that 25% of them drink RHRW. Quantitative microbial risk assessment (QMRA) analysis has been used to quantify the risk of exposure to harmful E. coli from RHRW utilised as potable water, based on the ingestion of 2 L of rainwater per day per capita. Results have revealed that the maximum E. coli exposure risk from the consumption of RHRW, without application of any household water treatment technique (HWTTs) and with application of alum only, were 100 and 96 respectively, for the estimated number of infection risk per 10,000 exposed households per year. This estimation has been done based on 7% of E. coli as viable and harmful. Conclusively, it is necessary that a form of disinfectant be applied to the RHRW before use.

Abstract
The security of water environment in the source region of the Yangtze River (SRYR) is vital to the water environment security of the whole basin. The results showed that the rivers in the SRYR were weakly alkaline and the values of total solid solubility (TDS), electrical conductivity (EC), turbidity concentration and salinity were higher than the values in the middle and lower reaches of the Yangtze River. The results showed that the dissolved trace elements detected displayed obvious regional distribution characteristics, showing a high concentration trend in the Chumar River, low in the Dangqu, and middle in the Tong River. All water quality indexes in the SRYR met the surface water environmental quality standard of class II based on GB 3838-2002 except Hg, while the average concentration of As exceeded 10 μg/L. The main enrichment elements in the SRYR were Li, Se, As and Pb, and their concentrations were far higher than the average concentration of the world rivers. Moreover, the HI and HQingrstion of children caused by As in the SRYR were greater than 1. This study could provide basic data for water environment protection and water resource management in the SRYR.

Abstract
Highly populated coastal environments receive large quantities of treated and untreated wastewater from human and industrial sources. Bivalve molluscs accumulate and retain contaminants, and their analysis provides evidence of past contamination. Rivers and precipitation are major routes of bacteriological pollution from surface or sub-surface runoff flowing into coastal areas. However, relationships between runoff, precipitation, and bacterial contamination are site-specific and dependent on the physiographical characteristics of each catchment. In this work, we evaluated the influence of precipitation and river discharge on molluscs' Escherichia coli concentrations at three sites in Central Italy, aiming at quantifying how hydrometeorological conditions affect bacteriological contamination of selected bivalve production areas. Rank-order correlation analysis indicated a stronger association between E. coli concentrations and the modelled Pescara River discharge maxima (r = 0.69) than between E. coli concentration and rainfall maxima (r = 0.35). Discharge peaks from the Pescara River caused an increase in E. coli concentration in bivalves in 87% of cases, provided that the runoff peak occurred 1–6 days prior to the sampling date. Precipitation in coastal area was linked to almost 60% of cases of E. coli high concentrations and may enhance bacterial transportation offshore, when associated with a larger-scale weather system, which causes overflow occurrence.

Published: April 2021

Background
Machine learning algorithms have been drawing attention at the joining of pathology and radiology in prostate cancer research. However, due to their algorithmic learning complexity and the variability of their architecture, there is an ongoing need to analyze their performance.

Objective
This study assesses the source of heterogeneity and the performance of machine learning applied to radiomic, genomic, and clinical biomarkers for the diagnosis of prostate cancer. One research focus of this study was on clearly identifying problems and issues related to the implementation of machine learning in clinical studies.

Methods
Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, 816 titles were identified from the PubMed, Scopus, and OvidSP databases. Studies that used machine learning to detect prostate cancer and provided performance measures were included in our analysis. The quality of the eligible studies was assessed using the QUADAS-2 (quality assessment of diagnostic accuracy studies–version 2) tool. The hierarchical multivariate model was applied to the pooled data in a meta-analysis. To investigate the heterogeneity among studies, I2 statistics were performed along with visual evaluation of coupled forest plots. Due to the internal heterogeneity among machine learning algorithms, subgroup analysis was carried out to investigate the diagnostic capability of machine learning systems in clinical practice.

Results
In the final analysis, 37 studies were included, of which 29 entered the meta-analysis pooling. The analysis of machine learning methods to detect prostate cancer reveals the limited usage of the methods and the lack of standards that hinder the implementation of machine learning in clinical applications.

Conclusions
The performance of machine learning for diagnosis of prostate cancer was considered satisfactory for several studies investigating the multiparametric magnetic resonance imaging and urine biomarkers; however, given the limitations indicated in our study, further studies are warranted to extend the potential use of machine learning to clinical settings. Recommendations on the use of machine learning techniques were also provided to help researchers to design robust studies to facilitate evidence generation from the use of radiomic and genomic biomarkers.

Published: April 2021

This research attempts to investigate the grammatical errors occuring in the official website of Indonesia’s tourism managed by the Tourism and Creative Economy Ministry of the Republic of Indonesia. It classifies the grammatical errors based on their lingustic categories. The data used in this research were taken from the articles containing grammatical errors. The results show that from 11037 words, 150 errors (13.59 per 1000 words) were found. The errors were evenly distributed across the three menus under investigation, with those in the News menu (15.46 errors per 1000 words) being slightly greater than those in the Discover Indonesia menu (12.97) and the Events menu (12.65). Furthermore, of the 150 errors, 131 (87.33%) belong to the syntactic category and only 19 (12.67%) belong to the morphological category. Out of the 19 morphological errors, the most frequent errors occured in the incorrect use of nominal modifiers (9 or 47.37%), followed by the incorrect use of third person singular verb (5 or 26.32%). As for the syntactic errors, the most common (102 or 77.87%) occured in the use of the noun phrase, followed by the incorrect use of the verb phrase (15 or 11.45%). Out of the 102 errors in the use of the noun phrase, most errors (65 or 63.72%) happened because of the omission of the articles, especially the definite article. The results seem to reflect the ability of the writers which do not clearly understand about the occasions when the definite article must be used.

Published: April 2021

Lignin is an organic polymer compound that is difficult to degrade in the environment because of its very complex structure consisting of an aromatic ring group and three carbons in the side chain. This exploratory study aims to determine whether white rot fungi isolated from wastewater from eucalypt pulp and weathered wood are lignolytic and the ability of the isolates to degrade tannins as an approach in the lignin degradation process. The experimental design is divided into two stages, namely: 1) Isolation of fungi that have the ability to degrade tannins quantitatively and qualitatively as well as characterization of fungi morphologically (macroscopic and microscopic). 2) Testing the ability of superior white rot fungus isolates in degrading tannins at concentrations of 0.5%, 1%, 1.5% and 2% of tannins. The brown zone formed in white rot fungal isolates was measured the zone diameter and intensity of the brown color. The results of this study indicate that of the 29 isolates obtained, there were five superior isolates capable of degrading tannins, namely isolates LD06, LD07, BE01.3, BE01.4 and BE02.2. BE01.3 was isolated at 2% tannin concentration, the second largest diameter of the brown zone after LD06 isolate and the highest brown color intensity level three with a slightly dark brown color intensity, namely slightly blackish brown.
