Published: December 2021

Abstract
The Peusangan watershed is home to hundreds of communities and approximately to fifty individuals of the endemic wildlife Sumatran elephants (Elephas maximus sumatranus). Human-elephants conflict (HEC) is a competition in the intersection of needs that has a negative impact on the community welfare and elephants. Elephants are protected wildlife that must be preserved, while at the same time there are socio-economic interests of the community which must also be guaranteed to be protected from possible damage due to the movement of the elephants. This study aims to determine the risk level by using a descriptive quantitative approach to identify the level of risk in the village area which is directly adjacent to the home range and not directly adjacent to the home range in the Peusangan watershed area. The method used is observation. The research sample was taken by purposive random sampling. Data collecting in the form of questionnaires and interviews. Data on the risk level of human elephants conflict were analyzed using the risk level formula. The hypothesis test of this study was carried out by analyzing the Independent Sample Test. The results of the study indicate that there are differences in the level of risk in areas that are directly and not directly adjacent to the Home Range with tcount
value of 3.384 > ttable
which is 1.984467. The criteria for the level of risk in areas directly adjacent to the home range have a low risk level and outside the home range have a medium risk with a level of hazard (68%), vulnerability (60%) and capacity (26%). Differences in risk levels refer to the implementation of conflict mitigation strategies, knowledge, attitudes and actions of the community in responding to human elephants conflict.

Published: December 2021

Abstract
The determination of the drying temperature and time depends to the characteristic of the mushrooms. The use of low temperatures causes the mushrooms to not fully ripen, if the temperature is too high the protein contained in the mushrooms can be denatured and drying too long will change the color of the mushrooms to brown and change its taste. Research on the processing of oyster mushrooms as a raw material for natural flavoring, it is carried out to determine the quality flavoring produced through a descriptive test of the test parameters, color, aroma, taste and texture by variations the temperature 60¼C and 70¼C in drying time 6, 7 and 8 hours. The results of descriptive test of the sixth color of the flavoring have an intensity of attractive colors are light brown; Descriptive taste test F1, F2 and F5 have the intensity of the taste is rather pleasant, the umami is weak while F3, F4 and F6 have taste is quite good, umami tastes; Descriptive test of the six flavoring textures has a good intensity and; Descriptive test of the sixth aroma of flavoring has a slightly fragrant aroma intensity, the aroma of the material is not too smelly. The conclusion of the research is that temperature and drying time do not affect quality of color, aroma and texture. However, they affect the taste where the temperature 60¼C for 8 hours and a temperature of 70¼C within 7 and 8 hours have enough delicious taste with tasteful umami.

Published: December 2021

Abstract
The operation of the pivot type trailer on a two-wheeled tractor on flat land shows that it is more ergonomic than conventional trailers, but for testing on sloping land it has never been tested. Therefore, this study aims to analyze ergonomics, especially the operator’s workload on the operation of a pivot-type trailer on a two-wheel tractor on a sloping land. The calculation of the operator’s workload is based on heart rate measurements, where three operators have their heart rate data taken during the activity of operating a two-wheeled tractor in pulling a trailer. The workloads analyzed are qualitative and quantitative workloads. The results showed that the operation of conventional trailers for land slopes of 0°, 10°, and 30° respectively showed IRHR values of 1.23, 1.24, and 1.31 or the level of work “light”, “light”, and “light”. While using a pivot type trailer, the IRHR values are 1.20, 1.27, and 1.55 or the work levels are “light”, “light”, and “medium”. The average energy consumption rate of operating a conventional trailer is 2.54 kcal/hour.kg-bb (kilocalories per hour per operator’s weight), while using a pivot type trailer 2.60 kcal/hour.kg-bb. The high level of operator workload is largely determined by the skill of the operator in operating the trailer, which requires training in its operation. This causes the operator’s workload to operate on pivot type trailers higher than conventional trailers. However, from the aspect of operator comfort and safety, pivot-type trailers are superior, especially when turning.

Abstract
Indonesia aims to decarbonize the energy sector by accelerating the use of new and renewable energy, expected to reach 31% of total energy supply in 2050. One of important tools to achieve the target is renewable energy potential maps including hydro energy potential maps. Yet, existing hydro energy potential maps have several weaknesses such as sites coordinate not on the river network. This study aims to update and to improve the run-off river system energy hydro maps by using a novel method considering multiple factors that are head values, discharge river, gravity, and the efficiency of the hydro system. In calculating the head value, we use DEM data from SRTM 1 arc second to estimate difference between upstream and downstream elevations. We also did Q90 modeling using WFLOW software as generate the discharge value. In the end, we verified the maps by using field measurement data in 776 sites from previous study. As a result, we estimate the total potential of hydro energy with the run-off river system in Indonesia reaches 94,627 MW distributed in 52,566 sites.

Authors: Puspitasari W , Hisyam E S , Gunawan I 
Published: December 2021

Abstract
Continuous and excessive use of groundwater causes a decrease in the water table, as well as drought during the dry season. Land use change causes reduced water infiltration, leading to flooding and inundation during the rainy season. This happened in KayuBesi Village, which is located in PudingBesar District, Bangka Regency. The purpose of this planning is to determine the dimensions of the rain water harvesting pool integrated with infiltration wells in the village office as the center of the village government and the mosque as the center of worship. The method used to calculate the volume of rainwater collected in a rain water harvesting pond is the result of substitution and modification made by Maryono from the relationship between discharge, volume of rainwater, and duration of rain with the relationship between discharge, speed of rainwater, and the cross-sectional area of the gutter pipe. The method used to calculate the depth of the infiltration well is the Sunjoto method. The results of the planning for the KayuBesi Village Office obtained the dimensions of the rain water harvesting pool with a pool length of 5 m, a pool width of 4 m and a pool height of 1.5 m, as well as an infiltration well with a diameter of 1 m and a depth of 2.5 m, while for the KayuBesi Village Mosque obtained the dimensions of the rain water harvesting pond with a pool length of 6 m, a pool width of 5.5 m, and a pool height of 1.6 m, as well as an infiltration well with a diameter of 1 m and a depth of 4.5 m.

Published: December 2021

Abstract
The development of Kediri City in various sectors, such as industry, agriculture, and population growth, also increases water. The utilization of groundwater is still a major mainstay in this area. The utilization of groundwater includes the construction of production wells for irrigation and raw water. The aquifer susceptibility should be considered during groundwater exploitation to minimize a negative impact on the environment. This research aims to analyze the susceptibility of the aquifer to pumping in Kediri City, which is helpful for planning and making decisions in the management of groundwater resources. The determination of aquifer susceptibility is based on aquifer response characteristics, aquifer storage characteristics, allowable subsidence of groundwater level, and depth to the groundwater table. Based on those parameters, it can be concluded that the aquifer susceptibility on groundwater utilization in Kediri City is at moderate and high levels. Areas with moderate aquifer susceptibility are located on the west side of Kediri City, and high aquifer susceptibility is in the middle to the eastern side of Kediri City.

Authors: Syafarini H , Hendrayana H , Winardi S 
Published: December 2021

Abstract
The karst area on Rote Island dominates more than 60% of the Island. The land surface conditions in karst areas are generally dry, while below the subsurface is the potential for abundant water resources. This study aims to assess groundwater vulnerability using the APLIS (Altitude, Pendiete/Slope, Lithology, Infiltration, and Soils) method that will integrate with Geographic Information System (GIS) technique. The parameters used are elevation, slope, lithology, infiltration zone, and soil type. Slope and elevation are obtained from DEM maps, the soil is obtained from soil type maps, while lithology and infiltration zone are obtained from geological maps. The lithology and the infiltration zone in APLIS method analysis have a high role in determining the level of groundwater vulnerability. The groundwater vulnerability in Rote Island was divided into four classes: very low in the Northeast, low in the South, moderate in the East and North, and high in the East and West part of the Island. It explains that a high level of groundwater vulnerability in Rote Island needs to be used as a groundwater protection zone.

Published: December 2021

Abstract
Randublatung groundwater basin is one of the groundwaters basins with massive utilization of groundwater pumping. However, the knowledge of the comprehensive hydrogeological system in this groundwater basin is limited, so this research aims to determine a comprehensive hydrogeological conceptual model of the Randublatung groundwater basin. The methodology was conducted by collecting secondary and primary data of deep and shallow wells to evaluate boundaries of pattern and direction of groundwater flow and develop the aquifer system’s geometry. The result shows that the groundwater flow boundaries are Grogol River in the west, Wado River in the East, Bengawan Solo river in the South as a river boundary, and Rembang Mountains in the North as a constant head boundary. Therefore, groundwater flows from the hills area to the Bengawan Solo River and the north as the river’s flow. Based on the log bor evaluation, the aquifer system of the study area consist of an unconfined aquifer with a maximum thickness of 20 m and three layers of confined aquifers with thickness vary between 8 to 60 m. the hydraulic conductivity of the aquifers depends on the aquifer’s lithology range from sand, gravel, limestone, and sandstone. This hydrogeological conceptual model provides essential information for numerical groundwater models in the middle of the Randublatung groundwater basin.

Published: December 2021

Abstract
The community of Randublatung basin and its surroundings (Grobogan, Blora, and Bojonegoro Regencies) using groundwater for agricultural, farming, and daily needs. However, these activities can contaminate the groundwater through nitrate and chloride in fertilizers, pesticides, animal waste, and household waste. Therefore, it is crucial to know the amount of nitrate and chloride content in the groundwater of The Randublatung basin and its surroundings. This research aims to analyze nitrate and chloride content and the ratio between ions in the groundwater of The Randublatung basin and its surroundings to find contaminant resources. The method to analyze the nitrate and chloride content is using Ion Chromatography. The analysis result from 35 samples of groundwater shows that the average nitrate content in dug wells samples is 10.06 mg/L, while the average from pump wells is 6.31 mg/L. The average chloride in dug wells samples is 43.65 mg/L, and the average from pump wells is 54.57 mg/L. These nitrate and chloride level are still in safe category based on Health Ministry Indonesia and WHO. The nitrate: chloride ratio in dug wells is 1:5, 1:9 from pump wells. The ratios indicate that the nitrate’s resource is associated with the on-site sanitation and will increase if there is no mitigation action to the contaminant resource.

Abstract
Energy has an important role in achieving social, economic and environmental goals, with energy being a driving force for the economy and a form of defense against the state. Because energy supports the supply of fuel, electricity and infrastructure so as to support a stable defense. The increasing needs of the community in the transportation sector and the decreasing availability of fossil energy. The Indonesian government is trying to find alternative energy as a substitute for fuel oil, namely by using electric vehicles. With the development of electric vehicles in Indonesia, it is expected to be a solution and can support the achievement of clean and environmentally friendly energy. Electric vehicles can reduce pollution and exhaust emissions due to the use of fuel oil in two or four-wheeled vehicles. In addition, using electric-fueled vehicles will certainly reduce the energy crisis and import fuel oil. In support of clean and environmentally friendly energy, Indonesia has supported the Paris Agreement policy to reduce carbon emissions in the transportation sector. The author tries to discuss the use of electric vehicles through current policies and applications and is associated with reducing carbon emissions through the use of electric cars. At the end the researcher will provide strategic recommendations related to the use and development of environmentally friendly electric vehicles to be developed in Indonesia in order to reduce carbon emissions in the transportation sector.

Published: December 2021

Abstract
Cognitive networks have evolved to cope with uncertain environments in order to make reliable decisions. Such decision making circuits need to respond to the external world in efficient and flexible ways, and one potentially general mechanism of achieving this is grounded in critical states. Mounting evidence has shown that brains operate close to such critical boundaries consistent with self-organized criticality (SOC). Is this also taking place in small-scale living systems, such as cells? Here, we explore a recent model of engineered gene networks that have been shown to exploit the feedback between order and control parameters (as defined by expression levels of two coupled genes) to achieve an SOC state. We suggest that such SOC motif could be exploited to generate adaptive behavioral patterns and might help design fast responses in synthetic cellular and multicellular organisms.
EnGRaiN: a supervised ensemble learning method for recovery of large-scale gene regulatory networks
Authors: Aluru Maneesha , Shrivastava Harsh , Chockalingam Sriram P , Shivakumar Shruti , Aluru Srinivas 
Published: December 2021

Abstract

Motivation
Reconstruction of genome-scale networks from gene expression data is an actively studied problem. A wide range of methods that differ between the types of interactions they uncover with varying trade-offs between sensitivity and specificity have been proposed. To leverage benefits of multiple such methods, ensemble network methods that combine predictions from resulting networks have been developed, promising results better than or as good as the individual networks. Perhaps owing to the difficulty in obtaining accurate training examples, these ensemble methods hitherto are unsupervised.

Results
In this article, we introduce EnGRaiN, the first supervised ensemble learning method to construct gene networks. The supervision for training is provided by small training datasets of true edge connections (positives) and edges known to be absent (negatives) among gene pairs. We demonstrate the effectiveness of EnGRaiN using simulated datasets as well as a curated collection of Arabidopsis thaliana datasets we created from microarray datasets available from public repositories. EnGRaiN shows better results not only in terms of receiver operating characteristic and PR characteristics for both real and simulated datasets compared with unsupervised methods for ensemble network construction, but also generates networks that can be mined for elucidating complex biological interactions.

Structural feature-driven pattern analysis for multitarget modulator landscapes
Authors: Namasivayam Vigneshwaran , Stefan Katja , Silbermann Katja , Pahnke Jens , Wiese Michael , Stefan Sven Marcel 
Published: December 2021

Abstract

Motivation
Multitargeting features of small molecules have been of increasing interest in recent years. Polypharmacological drugs that address several therapeutic targets may provide greater therapeutic benefits for patients. Furthermore, multitarget compounds can be used to address proteins of the same (or similar) protein families for their exploration as potential pharmacological targets. In addition, the knowledge of multitargeting features is of major importance in the drug selection process; particularly in ultra-large virtual screening procedures to gain high-quality compound collections. However, large-scale multitarget modulator landscapes are almost non-existent.

Results
We implemented a specific feature-driven computer-aided pattern analysis (C@PA) to extract molecular-structural features of inhibitors of the model protein family of ATP-binding cassette (ABC) transporters. New molecular-structural features have been identified that successfully expanded the known multitarget modulator landscape of pan-ABC transporter inhibitors. The prediction capability was biologically confirmed by the successful discovery of pan-ABC transporter inhibitors with a distinct inhibitory activity profile.

Availability and implementation
The multitarget dataset is available on the PANABC web page (http://www.panabc.info) and its use is free of charge.
