Authors: Sulaeman Y , Cahyana D , Husnain  , Nursyamsi D 
Published: May 2021

Abstract
Black soils are dark in color, having soil organic carbon, high base saturation and generally good in soil structure. Having relatively higher soil organic carbon, which is declining due to intensive cultivation, therefore, the conservation and wise use of these soils are of great important. This study aimed to identify spatial distribution of black soils in Indonesia. We used available national soil maps as reference. The identification was derived from the following: (i) collated available, published soil maps, (ii) studied map legends and identified mapping unit, (iii) plotted mapping unit, (iv) calculated the coverage based on proportion of Mollisols in given map units, and (v) did spatial cross tabulation with slope map and parent material map. Results show that black soils cover 6.3Mha and are categorized into 9 soil great groups (Hapludolls, Haplustolls, Endoaquolls, Argiudolls, Argiustolls, Rendolls, Calciustolls, Haprendolls, and Epiaquolls). We argue this has potential to be used as general guide for implementing conservation techniques.

Abstract
The Kuranji watershed has a complex problem which cannot be studied with a single scientific approach. In addition to an ecological approach it is also necessary to consider social and economic influences. Conserving areas that have a negative impact on watersheds, such as critical lands, is one of the efforts made to conserve watersheds will reducing costs and speeding up the recovery. The aim of this research is to estimate the economic value of the water yield of the Kuranji watershed on land conservation efforts. To get the economic value of water yield in the watershed, the non-market price approach method is used with the Contingent Valuation Method (CVM). The results showed that there were 356.10 ha of critical land in the Kuranji watershed that could be conserved. The value of water yield in existing land use conditions is greater than water yield in land use conditions influenced by conservation efforts. In this study, it was determined that the estimated economic value of water yield in the Kuranji watershed is 272 IDR/m3 of water. This is supported with a conservation value of 80% of critical land.

Abstract
Mount Sinabung was active again in 2010 after 400 years of dormancy and it is still erupting to date. The eruptions produced volcanic ash which blanket the soil surface. The distribution of volcanic materials was monitored by using Landsat Satellite which covers an area of 30, 320 Ha in 2018, then in 2019, it changed to 1, 371 Ha. After eruptions for 10 years, we believed soil characteristics are changed. The objective of this study was to characterize soil properties in the vicinity of Mt. Sinabung. There were 34 soil samples taken at a depth of 0-20 cm with a total research area of 4, 517.25 Ha. The samples were analyze for chemical properties included pH (H2O), total N, organic carbon, exchangeable base cations, and cation exchange capacity (CEC). The results showed that the pH (H2O) ranged from very acidic to neutral (4.14-6.52). The total N low to high category (0.13-0.60%). Organic carbon low to very high (1.73-13.05%). The exchangeable base cations have a high concentration with values of K (1.60-2.98 cmol kg−1), Na (3.72-7.45 cmol kg−1) and Mg (5, 79-12.15 cmol kg−1) respectively. Cation exchange capacity (CEC) showed high to very high category values (11.78-97.71 cmol kg−1). Volcanic ash provides many benefits to soil properties. This indicates that volcanic ash enrich soils by providing nutrients to the soils aftermath of volcanic eruptions.

Abstract
Serayu watershed, the largest watershed in Central Java Province of Indonesia, have various condition in the catchment area. Drawback of environmental services occurred in Banjarnegara, Wonosobo and Purbalingga regency due to intensive agriculture activities in the catchment area. However, suitable protected catchment area performed in Banyumas regency as part of Serayu watershed. Nature landscape and water quality (e.g., river and spring) are potential for tourism and domestic water resource. Nowadays, population growth and economical reason may threaten environmental services especially in catchment area. The research aim to identify waterfall potential as ecotourism development in Banyumas regency. Ecotourism Environmental Protection (EEP) approach already implemented in Asian mainland and appropriate tool for describing environmental protect measurement and its effect. EEP modified variables with Analytical Hierarchy Process (AHP) analysis were applied with focusing on water resource and conservation especially on waterfall ecotourism development. Identification of waterfall and survey of local communities, natural community, and government were conducted. We explore 109-waterfall in 17 districts of Banyumas regency with less than 20% manage by local or regional government. Third sector intervention (such local-or regional government and private sector) is indispensable for improving waterfall value as ecotourism attraction. In attractive waterfall destination, local people including local organisation receive economic benefit and might improve their welfare. Ecotourism of waterfall in Banyumas regency is promising strategy for water conservation in catchment area.
Numerical Model for Quantifying the Function of Soil Erosion and Sediment Transport Controls at Slope Agricultural Lands
Authors: Apip  
Published: May 2021

Abstract
The objective of this study was to build a numerical model that has the capability to account for the effect of various water and soil conservation practice scenarios in reducing erosion rate and sediment loads along slope cultivated lands. As further, inter-rill and rill erosion were implicitly represented by the raindrop and overland flow soil detachments. The observed surface runoff and sediment concentration data in response to incoming water from the rainfall within selected agricultural river catchments were used to evaluate the performance of spatially distributed, processed-based Hillslope Erosion and Sediment Transport Model (HESTM). As erosion and sediment yield from slope lands are primarily determined by rainfall, surface runoff, topography, vegetative canopy cover, ground surface cover, soil erodibility, and sediment properties. Thus, several scenario-based control strategies according to three clusters of water erosion and sediment control measures had been examined. They are agronomic measures and soil management; field management; and mechanical approach. Accordingly, scenario-based water and soil conservation practices were designed for setup numerical experiments of the model at selected water catchments located in the Upper Citarum and Cimanuk River basins, West Java which dominated by planted seasonal crops (carrot and potato). The study area was discretized into a spatial resolution of 30 x 30 m for considering heterogeneity and control measures function in rainfall-runoff-erosion-sediment process mechanisms.

Abstract
Lake Diatas is surrounded by agricultural activities that cannot be separated from the use of synthetic pesticides. Improper use of pesticides may endanger the health of farmers. This research aims to observe the clean water resources, as well as the knowledge and safety practices of pesticides among farmers around Lake Diatas. Interviews were conducted with 30 heads of families who lived and farmed around Lake Diatas. The results showed that 40% of farmers utilized rainwater as clean water, 30% used shallow well water which most of the wells were open and have no concrete ring, which vulnerable to contamination. There were 11 active ingredients detected used by farmers with one type with highly hazardous and two of them were moderately hazardous toxicity. For farmers’ knowledge, 76, 7% of farmers know that the improper use of pesticides may cause health problems and environmental pollution. There were 73, 3% of farmers determine the dose of pesticide regarding packaging label, while the rest determine the dose from the seller recommendation and also trial and error. All of the farmer respondents used personal protective equipment during spraying but mostly only googles, gloves, and masks, and 40% of farmers experienced health problems after spraying. From the results of the study, it can be concluded that the practice of PPE practice on farmers who farm and live around Lake Diatas still needs to be improved to prevent more health problems that can be caused by pesticide application.

AbstractResearch on gluten-free noodles made from composite flour (modified cassava flour (mocaf), tapioca, cornstarch, and soybeans) has been carried out in previous studies. However, research on the shelf life of these noodles has not been carried out. Information on shelf life is intended to ensure product quality is in good condition when consumed and does not endanger consumers’ health. This research aims to determine the shelf life of gluten-free dry noodles made from composite flour (mocaf, tapioca, cornstarch, and soybeans). Determination of gluten-free dry noodles’ shelf life using Accelerated Shelf Life Testing (ASLT) with the Arrhenius approach based on the pattern of changes in water content. Gluten-free dry noodles are packed using polypropylene plastic with a thickness of 0.09 mm. The packaged noodles were then stored at different temperatures, 25°C, 35°C, and 45°C. The parameter observed was moisture content on days 0, 14, 28, 35, and 42 days. The result showed that water content tends to increase during storage of gluten-free dry noodles from composite flour (mocaf, tapioca, cornstarch, and soybeans). Gluten-free dry noodles from the composite flour (mocaf, tapioca, cornstarch, and soybeans) stored at 25°C had the most suitable shelf life, around 161 days.

Abstract
As a traditional food, tofu is a very popular food for Indonesian people. Tofu is a type of food that is produced from soybeans through a series of stages, one of which is the boiling stage. This stage plays a major role in determining the quality of the results. Although steam tofu technology has long been found with a number of advantages, tofu craftsmen generally still use the traditional method of boiling soybean porridge. This then makes the tofu produced has low quality. This study aims to introduce and observe the advantages of steam boiler technology in improving the boiling process of traditional soybean porridge. The research begins with the manufacture of a vertical fire pipe steam boiler made of stainless steel. The boiler is made with a diameter of 78 cm and a height of 120 cm. The steam boiler is designed with 7 fire pipes equipped with a chimney at the top. The steam boiler is designed and constructed in a laboratory, then applied to a small tofu processing industry with a capacity of 200 kg of dry soybeans per day. The activity of observing the performance of the steam boiler was carried out for several months. The results of the analysis show that: (1) the steam boiler has been functioning properly, (1) producing tofu with the boiler is more efficient, time saving, and cost-effective (less fuel), (2) quality of tofu produced with the boiler is better, especially when viewed from the aspect of taste.

Abstract
Research on stingless bee at several Meliponiculture (stingless beekeeping) sites in West Sumatra, including at Universitas Andalas Campus Complex, had been conducted from April to December 2019 by using direct survey and direct collection methods on stingless bee worker at their colony entrances. A total of 18 stingless bee species that belong to five genera were collected. Tetragonula was the genus with the highest in species number (8), followed by Homotrigona (5) and Lepidoptrigona (3). Meanwhile, Heterotrigona and Geniotrigona were only represented by a single species each despite their popularity among West Sumatra beekeepers. Universitas Andalas Campus Complex harbours the highest species number of stingless bee (10), followed by stingless beekeeping site in Lubuk Minturun (7). Only 2-4 stingless bee species bred elsewhere stingless beekeeping sites. We presume that the difference of species number recorded in various stingless beekeeping sites indicated the complexity of this bee species within the variety of habitats.
How to Reclaim Your Dragons? A Retrospective Review on Odonatology in West Sumatra, Indonesia
Authors: Janra M N , Herwina H 
Published: May 2021

Abstract
Dragonflies and damselflies (Odonata) were not really popular subjects for biological studies at least until a decade ago in West Sumatra. In many scientific publications published by Lieftinct, a colonial era odonatologist, not many localities in West Sumatra mentioned as the origin of his odonata specimens. In this study, we intend to review the extent of current odonatological works in West Sumatra to gain perspective on the ongoing scientific aspects of this taxon. We used literature study method to compile data from historical and recent bibliographies, published works and other resources regarding dragonflies in West Sumatra. As result, from around 294 odonate species ever recorded in Sumatra Island, 98 species have been recognized from within the borders of West Sumatra Province with more than half recently reobserved. Albeit most publications are taxonomical and inventorial in their nature, further survey works are still needed to gain thorough insight on West Sumatran odonates. Meanwhile, the current studies and researches indicate the possibilities that dragonflies can also be integrated into the wider aspects, such as ecotourism, pest management, landscaping, environmental impact assessment, aesthetic and many others. Hence, introducing odonates as fascinating study object to the new generation of biologists can help furthering the advance and diversification of odonatological study in West Sumatra.

Abstract

Background
Hypertension is a growing public health emergency in rural sub-Saharan Africa. Based on the known influence of religious leaders in rural sub-Saharan Africa and our prior research, we explored perspectives of religious leaders on hypertension and potential strategies to improve hypertension control in their communities.

Methods
We conducted 31 in-depth interviews with Christian (n = 17) and Muslim (n = 14) religious leaders in rural Tanzania. Interviews focused on religious leaders’ perceptions of hypertension and how they could play a role in promoting blood pressure reduction. We used interpretative phenomenological analysis, a qualitative research method, to understand religious leaders’ perspectives on, and experiences with, hypertension.

Results
Three main themes emerged during analysis. First, we found that perceptions about causes, treatment, and complications of hypertension are influenced by religious beliefs. Second, religious beliefs can enable engagement with hypertension care through religious texts that support the use of biomedical care. Third, religious leaders are enthusiastic potential partners for promoting hypertension control in their communities. These themes were consistent between religion and gender of the religious leaders.

Conclusions
Religious leaders are eager to learn about hypertension, to share this knowledge with others and to contribute to improved health in their communities.
Living after Life
Authors: Taylor Matthew A 
Published: May 2021

AbstractMy second book project explores the paradox of how a period ostensibly characterized by increasingly materialist conceptions of life—roughly bookended by On the Origin of Species (1859) and the discovery of DNA’s structure (1953)—perpetuated a vitalist (yet murderous) metaphysics that became the lifeblood of modern Western thought. This metaphysics values living beings according to the degree they embody the supposed ideal of biological life: free agency. Not only does such a model come to authorize violence against certain populations deemed naturally unfree, it also demands—as an expression of superior vitality—mastering the Earth. I thus contend, against specific versions of new materialism and neovitalism, that extending vitality to encompass all things furthers rather than forecloses a worldview central to eugenics and climate change alike. In sections on the history of biology, evolutionary aesthetics, and literary model organisms, I exhibit both life’s horrific reach and its utter fictionality—exemplified in this essay through an examination of the genocidal impulses inherent to Gaia discourses old and new. Drawing on scholarship in Black studies, disability studies, biopolitics, queer theory, and animal studies, my project’s final section explores fugitive alternatives to life in two distinct late nineteenth- and early twentieth-century archives: silent film comedies of mortal imperilment and Black speculative fictions envisioning nonlethal (because nonvitalized) modes of being.

Published: May 2021

Abstract

Objective
Physical exercise shows benefits to executive functioning (EF), a cognitive process that is relevant to goal-directed planning, application of complex rules, and dynamic control of action. However, many older adults have not engaged in exercise due to social distancing measures implemented to combat the Covid-19 pandemic. The present study aims to administer a remote physical exercise training program to older adults in Canada and examine its effects on EF and mood, beginning with the collection of the following baseline data.

Methods
So far, nine older adults (78% females, 66–78 years-old) have completed a remote assessment that examines current physical exercise engagement, Covid-related distress, general mood, and executive behavior. In addition, the assessment included computerized tasks measuring various aspects of EF. Pattern analyses were used to characterize trends in baseline data.

Results
67% of participants reported undergoing no moderate-vigorous physical exercise in a typical week. Compared to other participants, more individuals in this subgroup performed at a lower rate on a higher-order EF task (i.e., the Balloon Analogue Risk Task). Similarly, more participants who endorsed higher Covid-related psychological distress performed worse in the same task compared to others (40% in the lower third of performance vs. 0%), and also endorsed more difficulties with organization.

Conclusions
These results suggest that those who do not engage in physical exercise are potential candidates to experience the mental health and cognitive benefits of a physical exercise training program.
