Abstract
Land use is a representation of activities and utilization of land resources by the community. Land use has a big influence on the hydrological condition of a watershed. One of the small watersheds, in general, is the Karajae watershed, but it has a very large impact on the City of Pare-Pare, and the surrounding community. The Karajae watershed is the main water source for the people of Pare-Pare and agriculture. This study aims to analyze land use patterns that have a major impact on hydrological conditions in the Karajae watershed. The analysis begins with remote sensing methods to interpret land use using Landsat 7 image data in 2010 and Landsat 8 imagery in 2020. Next, analyze the pattern of land use change in detail in each forest area with a geographic information system approach. Analysis of hydrological conditions using the Soil and Water Assessment Tools approach with the input of the land use data. Land use Change 2010-2020 in the Karajae watershed shows additional land use in the form of settlements, rice fields, and dryland agriculture as a form of community activity. There are two forest areas in the Karajae watershed, namely production forest and protected forest. Production forest is dominated by dryland agriculture in the form of corn, beans, and horticulture, while the protected forest is dominated by and secondary dryland forest. This has an impact on hydrological conditions that there are fluctuations in discharge and an increase in sediment a decade ago. Optimal application of forest functions reduces discharge and sediment. Different forest planning for each forest function and land use within. Production forest with many activities directed towards community-based forest management such as community forest and village forest. As for the Protected Forest, which is dominated by grassland and shrubs, forest rehabilitation is carried out.

Abstract
A coagulant is a chemical needed by water to help settle small particles that cannot settle on their own. Meanwhile, total suspended solids (TSS) result from filter dissolved solids by gravity deposition, usually in chloride particles, and indicate the sedimentation rate. This study aimed to determine the effectiveness of bio coagulants to reduce levels of total suspended solids (TSS) in liquid tofu waste to find out which one is more effective as a bio coagulant in liquid tofu waste. This research is experimental, consisting of 2 stages: the manufacture of charcoal from bio coagulants and the measurement of total suspended solids (TSS) levels. The data collected were tabulated and then analyzed descriptively. Three types of bio coagulants used were tamarind seeds, coffee husks, and cocoa pods. The results showed that there was a decrease in the TSS value before and after coagulation was given. The highest TSS reduction was obtained from bio coagulant charcoal from cocoa pods which reached 54.28% for a coagulant dose of 2 mg/l, while for a coagulant dose of 5 mg/l it could reduce TSS by 70.71%. It means the cocoa pods waste have a potential to use as coagulant to control sedimentation in the environment.

Abstract
Cervus unicolor is an animal with a protected status under government regulations in Kalimantan. Conservation efforts for this species can be done through captivity. This study aims to analyze the suitability of the area for captive C.unicolor with additional functions as educational tourism. The research location that will determine the feasibility of captive C.unicolor in Tanah Laut Regency, South Kalimantan consists of 3 selected locations. Data was collected by direct field observation and interviews. Secondary data collected in the form of thematic layers and other land characteristics data. Environmental characteristics that became the main study points in captivity of C.unicolor were analyzed descriptevely. The feasibility of the location for captivity was analyzed by weighting several parameters approach. Some of the feasibility parameters assessed are accessibility, topography, grazing area, shade, water sources, and savety aspects. The mapping of the assessed captive locations was analyzed using Arc Gis Software. The results of the analysis show that the location of the Gunung Kayangan tourist area is the most recommended area for captive C.unicolor. The disadvantage of this area compared to the other 2 options is the limited water source which can be overcome by optimizing existing water bodies as reservoirs for water supply for captive C.unicolor.

Abstract
One of the causes of decrease forest functions is deforestation. Deforestation is a nonforest cover change activity that affects the decrease function of forest ecosystems. South Sulawesi and West Sulawesi Provinces are two areas that have experienced high deforestation. The area of forest in South and West Sulawesi in 1990 amounted to 2,550,946.13 ha. The number decreased in 2019 amounted to 2,213,628.88 ha. This study aims to identify and understand the spatial model of deforestation based on biophysical driving factors in South Sulawesi and West Sulawesi Provinces from 1990 to 2019. Materials used in this study were Statistics Data Centers in 1990, 2000, 2010, and 2019, Deforestation Profiles at South Sulawesi and West Sulawesi, literature supporting research. Data analysis used PCA (Principal Component Analysis) method. The results of this research explain that the driving factors the occurrence of deforestation in each location of the most influential research is the factor of the road, the closer the forest area to the road the higher the public desire to penetrate the forest area in addition, facilitate agricultural activities to distribute forest products and logs felling. River factors also have a role in the occurrence of deforestation, the community is very dependent on water needs primarily for agricultural land and plantations. In addition, the slope and altitude factors are also quite influential on the occurrence of deforestation due to the clearing of land in a fairly flat area with low altitude as in the Regency Bone and North Luwu, South Sulawesi province is very visible influence over the topographic areas of mountains and steep as in the Regency of Mamuju and Mamasa Regency, West Sulawesi Province. Areas with such topography, have a low level of accessibility so that the pressure and disturbance are low enough from the community.

Published: November 2021

Abstract
DKI Jakarta is one of the provinces with the highest flood risk in Indonesia. 13 rivers divide Jakarta from upstream to downstream, one of which is the Ciliwung River. However, at this time, the Ciliwung River was asked to be one of the dirtiest rivers in the world. The purpose of this study was to determine the levels of physical parameters (TSS), chemical parameters (BOD, COD, Total Phosphate), and microbiological parameters (Total Coliform, Fecal Coliform) in the Ciliwung River, along with the potential health disaster risks from various parameters studied based on literature review. The method used is descriptive quantitative with secondary data sources in the form of monitoring data on the water quality of the Ciliwung River, which was carried out for four periods in April, June, July and August at 21 points spread along with upstream to downstream. The results showed that the physical, chemical and microbiological parameters had passed the specified standard thresholds and had the potential for a public health disaster due to exposure to organic compounds and microorganisms in the Ciliwung River. Further efforts related to disaster need to be carried out in a Penta helix manner so that disaster risk reduction efforts can be carried out as a whole.

Published: November 2021

Abstract
Periodic forest monitoring needs to be done to avoid forest degradation. In general, forest monitoring can be conducted manually (field surveys) or using technological innovations such as remote sensing data derived from aerial images (drone results) or cloud computing-based image processing. Currently, remote sensing technology provides large-scale forest monitoring using multispectral sensors and various vegetation index processing algorithms. This study aimed to evaluate the use of the Google Earth Engine (GEE) platform, a geospatial dataset platform, in the Vale Indonesia mining concession area to improve accountable forest monitoring. This platform integrates a set of programming methods with a publicly accessible time-series database of satellite imaging services. The method used is NDVI processing on Landsat multispectral images in time series format, which allows for the description of changes in forest density levels over time. The results of this NDVI study conducted on the GEE platform have the potential to be used as a tool and additional supporting data for monitoring forest conditions and improvement in mining regions.

Published: November 2021

Abstract
The Baikal Rift Zone hosts many hot springs with a wide range of temperature and physical-chemical conditions, which may harbour different niches for the distribution of microbial communities. We investigated microbial community composition and their functional activity in two alkaline hot springs with a temperature range of 34.4 to 73.6°C. Comparative analysis of the composition of the dominant taxa showed significant differences depending on the collection sites. In the community of high-temperature zones with a water temperature of 55-64°C, a high proportion of thermophilic bacteria Acetothermia (up to 57.9%), Deinococcus-Thermus (up to 50%), and Aquificae (up to 10.8%). Proteobacteria (29-77%) and Firmicutes (15-26%) dominate in the sulphide-free Garga spring (73-75°C). The functional analysis of the microbial community showed that the primary producers are cyanobacteria, anoxygenic phototrophs, and chemolithotrophic bacteria. At the terminal stages of the mineralization of organic matter, sulphate-reducing bacteria are the main destructors in the microbial communities in hot springs. The cyano-bacterial and sulfidogenic microbial communities play an important role in the formation of geochemical barriers and mineral formation.

Abstract
The results of studies of the chemical composition of water, travertine, and microbial mats in the Khoito-Gol mineral spring (Eastern Sayan) are presented. It was shown that the formation of mineral deposits, travertine, and microbial mat is connected with the active functioning of microorganisms and geological and geodynamic conditions. It has been revealed that the diversity of cyanobacterial and sulfur microbial mats increases as the distance from the springs of the thermal water grows. Microbial mats are hardened with carbonates being converted into solid travertine crusts that are built upon the top of older structures to form multi-meter domes. The concentration function of the microbial mats and thermal water showed higher coefficients of accumulation of nickel and beryllium.

Published: November 2021

AbstractBased on the studies conducted in 2012-2020 on the key plots of mixed fir tree woodlands that grow within the Ulan-Burgasy Mountain range, the authors identified a special nemoral group of lepidopterans, that typically inhabit ocean coastline mixed and broad-leaved forests. Another peculiarity of this area is the presence of species atypical for the major part of the Transbaikal Region:Spialia orbiferHbn.,Leucodonta bicoloriaDen. et Schiff.,Furcula bifidaBrahm (Sub-boreal group);Laothoe populiL. (Central Palearctic group); andFeralia sauberiGraes. (Palearchearctic group). The comparison of Lepidoptera faunas on the key plots and other forest and forest-steppe habitats in the Transbaikal Region revealed their high similarity (more than 80%) to the Ulan-Burgasy humid forests that grow near Baikal and mixed fir tree taiga forests of the Khamar-Daban Ridge.

Published: November 2021

AbstractWith regard to the problem of restoring the muksun (Coregonus muksun) population in Western Siberia by means of artificial regeneration, the genetic differentiation of natural populations and broodstocks of fish rearing farms “Forvat” and “Sobsky” was studied. Eighty-four sequences of mtDNA (3,006 bp) containing the highly polymorphic genes ND1 and ND2 were analysed. The differences between the populations of Western and Eastern Siberia were revealed. These findings must be taken into account when attempting to restore the species population in each particular region. The genetic closeness of the muksun from fish rearing farms “Forvat” and “Sobsky” with muksun from the Ob-Taz basin gives grounds for using these broodstocks for seeding the Ob and Taz rivers.

Published: November 2021

Abstract
The characteristics of the photosynthetic apparatus of coniferous growing in various forest types and climatic conditions of the Irkutsk region (Taishet, Bratsk, Shelekhov, Irkutsk districts) have been explored. The content of photosynthetic pigments, total, free, and bound water in the needles of P. sylvestris and L. sibirica were studied. Using a pulse fluorimeter PAM 2500 (Waltz, Germany), the chlorophyll fluorescence in needles was measured based on such induction curve indices as Fv/Fm, Y(II), NPQ, and ETR. According to the chlorophyll fluorescence induction curve parameters of Scots pine and Siberian larch needles growing in different forest growth conditions, the most effective potential of primary photochemical processes in PSII was observed in Scots pine. While studying the pigment fund of Scots pine and Siberian larch needles, it was found that the highest values of the content of chlorophyll (Chl) a, b, and carotenoids were observed in P. sylvestris and L. sibirica growing in the climatic and forest growth conditions of the Shelekhov district. It is assumed that the revealed characteristics of the parameters reflect the processes of adaptation of the photosynthetic apparatus to various environmental conditions during vegetation development, as well as its high plasticity in different climatic growth conditions.

Published: November 2021

Abstract
New data on the soils of mountain floodplains in the tectonic joints zone of the Mongol-Okhotsk Orogenic Belt on the example of the Upper Kerulen Basin are presented. Soil diversity is mostly determined by sedimentation conditions and drainage of the parent rocks. There are alluvial–humus (Fluvisol (Humic)), mucky–humus (Folic Fluvisol), dark–humus (Fluvisol (Mollic)), dark–humus gley (Gleyic Fluvisol) and dark–humus saline soils (Sodic Gleyic Fluvisol (Mollic)) were diagnosed. Tectonic movements of the earth’s crust lead to the appearance of shaftlike linear dams, blocking river flow through the valley. So, the Kerulen river changed the direction of the channel and go beyond the depression, embedding into its mountain frame. Current seismicity impact on soils appears locally at tectonically active positions of epigenetic areas, close to outputs of saline underground deep waters, in the form of surface soil salinity and hydrometamorphism.

Published: November 2021

ABSTRACT

Background
The relationship between intake of sugar-sweetened beverages (SSBs) and the risk of death in patients with chronic kidney disease (CKD) is unclear. We evaluated the association between SSB intake and subsequent overall mortality in CKD patients.

Methods
We included data from 3996 CKD patients who participated in the 1999–2014 National Health and Nutrition Examination Survey (NHANES). SSB intake was assessed by a 24-h dietary recall, grouped as none, &gt;0 to &lt;1 serving/day, 1 to &lt;2 servings/day and ≥2 servings/day. After adjusting for demographic variables, lifestyle, diet and comorbidities, Cox proportional risk regressions were applied to analyze the associations between the daily intake of SSBs as well as added sugar from beverages and all-cause mortality.

Results
In the whole research population, the median age at baseline was 67 years, 22% were Black and 54% were female. A total of 42% had stage 3 CKD. During an average follow-up period of 8.3 years, a sum of 1137 (28%) deaths from all causes was recorded. The confounder-adjusted risk of mortality was associated with an increase of 1 serving/day of SSBs, with all-cause mortality of 1.18 [95% confidence interval (95% CI)1.08–1.28], and intakes of increased 20-g added sugar/1000 kcal of total energy per day were associated with all-cause mortality of 1.14 (1.05–1.24). Equivalently substituting 1 serving/day of SSBs with unsweetened coffee [HR (95% CI) 0.82 (0.74–0.91)], unsweetened tea [HR (95% CI) 0.86 (0.76–0.98)], plain water [HR (95% CI) 0.79 (0.71–0.88)], or non- or low-fat milk [HR (95% CI) 0.75 (0.60–0.93)] were related to a 14–25% reduced risk of all-cause mortality.

Conclusion
Findings suggest that in the CKD population, increased SSB intake was associated with a higher risk of mortality and indicated a stratified association with dose. Plain water and unsweetened coffee/tea might be possible alternatives for SSBs to avert untimely deaths.

Published: November 2021

Abstract
The goal of this paper was to report a new variant of oesophageal atresia: an H-type congenital tracheo-oesophageal fistula associated with oesophageal segmental stenosis distal to the fistula. Although symptoms were present from birth, we did not differentiate the new anatomical variant preoperatively. The patient was treated by fistula ligation, segmental resection of the distal oesophagus and end-to-end anastomosis of the oesophagus by thoracoscopic surgery. Here we describe the clinical history and management of the newborn infant, together with diagnostic recommendations to prevent misdiagnosis in the management of this condition.
