Published: April 2023

Abstract
Living tissues dynamically reshape their internal cellular structures through carefully regulated cell-to-cell interactions during morphogenesis. These cellular rearrangement events, such as cell sorting and mutual tissue spreading, have been explained using the differential adhesion hypothesis, which describes the sorting of cells through their adhesive interactions with their neighbors. In this manuscript we explore a simplified form of differential adhesion within a bioinspired lipid-stabilized emulsion approximating cellular tissues. The artificial cellular tissues are created as a collection of aqueous droplets adhered together in a network of lipid membranes. Since this abstraction of the tissue does not retain the ability to locally vary the adhesion of the interfaces through biological mechanisms, instead we employ electrowetting with offsets generated by spatial variations in lipid compositions to capture a simple form of bioelectric control over the tissue characteristics. This is accomplished by first conducting experiments on electrowetting in droplet networks, next creating a model for describing electrowetting in collections of adhered droplets, then validating the model against the experimental measurements. This work demonstrates how the distribution of voltage within a droplet network may be tuned through lipid composition then used to shape directional contraction of the adhered structure using two-dimensional electrowetting events. Predictions from this model were used to explore the governing mechanics for complex electrowetting events in networks, including directional contraction and the formation of new interfaces.

Published: April 2023

Abstract
The capacity factor (CF) is a vital parameter used to quantify the performance and efficiency of a wind turbine. An increase in generation efficiency leads to higher wind power production, improving the economics within the growing global wind market. In this research, we use a data-driven statistical method to explore the contributions of the three main drivers of CF change: turbine aging, changes in wind speed, and technological improvements. We find that for the group of old turbines (operated before 2008) with an unchanging technical condition, wind increases contributed ∼10% to the increasing CF on average from 2010 to 2020. For new turbines (built from 2008 to 2020), technological improvements had a strong positive effect on CF from 2015 to 2020, exceeding the effect of wind increases and offsetting the effects of aging. On average, rising wind speeds increased CF by ∼5% per year, while technological improvements increased it by ∼12%. As the installed capacity of wind turbines grew, technological progress became the dominant driver in CF increase. However, poor site selection potentially compromised the positive effect on CF afforded by technology changes early in the decade.

Authors: Pham Y Lan , Holz Olaf , Beauchamp Jonathan 
Published: April 2023

Abstract
The first and most crucial step in breath research is adequate sampling, which plays a pivotal role in quality assurance of breath datasets. In particular, the emissions or uptake of volatile organic compounds (VOCs) by sampling interface materials present a risk of disrupting breath gas samples. This study investigated emissions and uptake by three interface components, namely a silicon facemask, a reusable 3D-printed mouthpiece adapter, and a pulmonary function test filter compatible with the commercial Respiration Collector for In-Vitro Analysis (ReCIVA) breath sampling device. Emissions were examined before and after (hydro-)thermal treatment of the components, and uptake was assessed by exposing each material to 12 representative breath VOCs comprising alcohols, aldehydes, ketones, carboxylic acids, terpenes, sulphurous and nitrogenous compounds at different target concentration ranges (∼10 ppbV and ∼100 ppbV). Chemical analyses of VOCs were performed using proton transfer reaction-time-of-flight-mass spectrometry (PTR-TOFMS) with supporting analyses via thermal desorption comprehensive two-dimensional gas chromatography-TOFMS (TD-GC×GC-TOFMS). The filter exhibited the lowest overall emissions compared to the mask or adapter, which both had equivalently high emissions (albeit for different compounds). Treatment of the materials reduced the total VOC emissions by 62% in the mask, 89% in the filter and 99% in the adapter. Uptakes of compounds were lowest for the adapter and most pronounced in the mask. In particular, 1-butanol, acetone, 2-butanone, 1,8-cineole and dimethyl sulphide showed negligible uptake across all materials, whereas ethanol, nonanal, acetic acid, butanoic acid, limonene and indole exhibited marked losses. Knowledge of emissions and/or uptake by sampling components is key to reducing the likelihood of erroneous data interpretation, ultimately expediting progress in the field of breath test development.

Abstract
Shallot (Allium ascalonicum L.) is one of the horticultural commodities that have high economic value in Indonesia. The caterpillar, Spodoptera exigua Hübner (Lepidoptera: Noctuidae), is an important pest of shallot crops which decreases both production and yield quality. Farmers commonly spray pesticides to control S. exigua. This can cause negative impacts on the environment and farmers’ health. Therefore, environmentally friendly control measures need to be implemented. Use of sex pheromone traps can be an alternative in controlling S. exigua. This research aims to study the effect of moonlight and rainfall on the number of male imagos of S. exigua captured in sex pheromone traps and to study the correlation of the number of S. exigua imagos captured on the percentage of infested leaves and shallot yield. This study was conducted from March to June 2016 in Labuhan Lombok Village, East Lombok Regency, West Nusa Tenggara (NTB) Province, Indonesia. Sex pheromone traps were randomly set on 12 shallot cultivation plots (Super Phillips variety). The number of male moths caught was recorded every 3-4 days, and then at the end of observations the percentage of infested leaves was determined. The number of captured male imagos of S. exigua had a significant linear relationship with the percentage of infested leaves and shallot yield with the correlation coefficient values of -0.607 and 0.829 respectively. The application of sex pheromone traps to control S. exigua on shallot, during moonlight and rainfall, has the potential to decrease both insecticide and production cost and to increase farmers’ income.

Published: April 2023

Abstract
Global climate change induced environmental stress such as salinity significantly impact growth and crop productivity. Red amaranth (Amaranthus tricolor L.) is a vegetable commodity that has high nutritional value, but its productivity will decrease when grown in saline area. Seed priming is one of the pre-planting treatment techniques used to increase plant growth under unfavourable conditions. Osmopriming is one of the priming techniques where the seeds will be immersed in a solution with a high osmotic potential, such as PEG (Polyethylene Glycol). The purpose of this study was to determine the morphophysiological response of red amaranth to osmopriming treatment under salinity stress. Complete randomized design was used to arrange this experiment containing two variables including seed osmopriming (0, 5% and 10% of PEG) and salinity stress (0, 50, and 100 mM of NaCl). Morphophysiological parameters were measured including plant height, number of leaves, root length, leaf chlorophyll content, proline content, oxalic acid content and Ca-oxalate crystal density. After seed osmopriming with 10% of PEG 6000 increased plant height, number of leaves and root length of red amaranth Under salinity stress. Chlorophyll content increased while proline, oxalic acid content and Ca-oxalate crystal density decreased on osmopriming with 10% of PEG 6000. Seed osmopriming enhances morphophysiological characters to overcome problems in cultivating of red amaranth on saline area.

Abstract
Indonesia produces large amounts of rice. However, almost every year, rice imports are still carried out to meet the needs of food stock, and supply in several regions still needs to catch up to demand. The application of rice cultivation technology contributes to increasing the productivity of cultivated rice products with the “Jajar Legowo System” (JLS). The purpose of this study is to compare the income of JLS cultivation and conventional systems (CS). This research applied the descriptive-analytic method from the survey. The purposive method was applied deliberately in determining the location of the study by considering certain objectives. This study uses a simple random sampling techniques to collect samples from 30 JLS and CS farmers. The collected data is first compiled, described, and then analyzed by quantitative research methods, namely, taking a sample from a population using a questionnaire as a data tool. The research results showed that the application of JLS rice cultivation technology significantly increased productivity (13.62%), income (29.88%), efficiency (18.90%), and benefits for rice farmers (8.53%) compared to that CS. Rice cultivation using JLS is appropriate in Indonesia to increase farmers’ income. The application of JLS can improve farmers’ income. This technology is feasible to develop in Indonesia.

Published: April 2023

AbstractSoybean is Indonesia’s important food crop, generally grown in monoculture. Global climate change can affect unfavourable environmental conditions and reduce soybean yields. Soybean yields can be increased by intercropping, which can improve the plant’s environmental conditions. One of the crops that can be intercropped with soybeans is corn because planting corn between soybeans can create a favourable microclimate for soybeans. This study aims to obtain the right population proportion in soybean and corn intercropping based on physio-morphological responses. This research was conducted in Kasihan, Bantul, Yogyakarta Special Region, in July-November 2021, with a single-factor experimental method arranged in a single plot design. The treatment was the proportion of soybean and corn population, consisting of 4 proportions, i.e. 2:1, 3:1, 4:1, 5:1, and monoculture soybean and corn as controls. The variables observed were leaf area, dry weight, chlorophyll content, stomatal density, number of pods, seed weight, and soybean yield. The results showed that the proportion of soybeans and corn intercropping population did not affect chlorophyll content and stomata density. A population proportion of 3:1 produces the number of leaves and specific leaf area, the number of pods, and pod weight per plant higher than monoculture soybeans and other intercropping population proportions.

Abstract
Indonesia is the largest palm oil producer in the world. One of the provinces with the largest oil palm area in Indonesia is the West Kalimantan Province, which 1,89 million ha. Of this total plantation area, 54,7% (1.456.534 ha) are smallholder plantations. The use of huge area for oil palm cultivation is often associated with global warming because it is considered to source of carbon release from irresponsible cultivation processes. The main problem of oil palm independent smallholder plantations is the low productivity because of does not implementing the sustainable cultivation technologies. This study was conducted to describe the process of oil palm cultivation carried out by oil palm independent small holder in West Kalimantan Province. The research has been conducted through structured interviews in four districts with a purposive sampling method. The results showed that the most sustainable agronomic activities that have been carried out by oil palm farmers are plantations establishment in non-forest estate (APL) and use of certified seeds. Meanwhile, sustainable agronomic activities that have not been carried out by most oil palm farmers include without-burning land clearing, weed and pest-diseases control according to guidelines, and fertilization, castration, pruning, and harvesting rotation as recommended. On average, the productivity of oil palm independent smallholder in West Kalimantan is about 8,36 tons of FFB/ha/year, still below the Indonesian national average of oil palm productivity. These results indicate that most of oil palm independent small holder in West Kalimantan Province need to increase their agronomic capacity so that their productivity can increase.

Abstract
Flood disaster in Mandailing Natal Regency, North Sumatera, Indonesia is challenging due to its barriers to reduce the disaster impact. Flood disaster mitigation should be prepared for both structural and non-structural alternatives to apply. Meanwhile, the government seems to face budget allocation and geographical condition of the area to choose the better alternatives. This research aims to investigate the suitable alternative to be applied in the study area as flood disaster mitigation. There are three alternatives: (1) river channel modification, (2) earth-embankment dam construction, or (3) rainwater harvesting (RWH) application. The investigation is carried out through hydrological analysis, hydraulics analysis, and numerical analysis of channel and dam by using HEC-RAS and Geo-Studio supporting tool. Meanwhile, rainwater harvesting is computed based on a mathematical model from previous studies. Since the alternative is chosen because of the runoff reduction capability and budget expenditure prediction, rainwater harvesting seems to be the more recommended to be applied in the study area. The RWH could make 86.36% runoff reduction. Despite river channel modification could extract almost 100% of runoff, the allocation for the construction is too high for the government to handle.

Published: April 2023

Abstract
Climate change is indicated by extreme weather changes, namely drought on agricultural land, thus limiting crop growth. The availability of rice as a food source in developing countries has not met the increasing food needs of the population. The low planting area and productivity, which are said to be the triggers for the problem, can be overcome by nutrient management on dry land. Iron serves a function in the physiology and metabolism of plants. Iron sprayed on the leaves in the form of nano Fe2O3 can increase the efficiency of nutrient absorption by plants. This study aims to evaluate the effect of the application of nano Fe concentration on rice growth in drought-stress conditions. The study was conducted in the Sleman experimental field using the Split Plot Design method with two factors (water content of 100; 50% and nano-Fe concentration of 0; 0.5; 1; 1.5; 2 ppm). Based on the results of the study showed that there was an independent effect of treatment on growth. Spraying nano Fe 0.5-1 and 1.5-2 ppm reduced membrane damage by 3.27% and 8.25% respectively, and there was a negative correlation between membrane damage and growth parameters.

Published: April 2023

AbstractIn their business operations, mining companies that process natural resources must deal with environmental degradation. The companies shall do environmental preservation to mitigate global warming due to business processes and make an environmental responsibility report to ensure a sustainable business. Whether the COVID-19 pandemic affects environmental responsibility is the focus of this study. The pandemic disrupts all sectors, including the mining industry. Therefore, this study investigates the level of environmental reporting made by mining companies before and after the COVID-19 outbreak. In addition, this study also investigates the determinants of the level of environmental reporting disclosed in either the annual report or sustainability report. Thirty-seven companies listed on the Indonesia Stock Exchange in the mining sector in 2019 and 2020 were used as a sample. Results from the Wilcoxon signed rank analysis suggest that the level of environmental disclosure increased following the epidemic’s spread, contrasted to levels prior to the outbreak. The multiple regression analysis reveals that public ownership and size are likely to enhance environmental disclosure. Meanwhile, leverage tends to reduce environmental disclosure. The analysis offers perspective on the capital market authority agency’s new strategy aimed at enhancing aspects that could influence environmental responsibility disclosure.

Abstract

Orthosiphon aristatus (Java Tea) is a traditional and economically valuable medicinal plant with different pharmaceutical activities for preventing various diseases. Air temperature is one of the environmental elements that have an impact on plant growth and herbal production. The study aimed to assess how java tea plants respond to high air temperatures and to learn if soil with compost fertilizer may have a substantial impact on plant growth. The research was arranged using a completely randomized design, with air temperature as the main factor with three replicates for each treatment. Plastic Pots of java tea plants were maintained in the greenhouse (control) for three months and in the growth chamber day/night temperatures of 25/25°C, 30/25°C, 35/25°C, 40/25°C, 45/25°C and 50/25°C. Plants placed in a growth chamber showed significantly affected by temperature by comparing treatments in the greenhouse (control). Java tea plants kept at 30/25°C and 35/25°C had considerably higher plant height, leaf numbers, fresh and dry weight values than other treatments, whereas the 40°C treatment had the greatest growth decline, reduced leaf number, dry weight, and fresh weight. Moreover, all plants subjected to 45/25°C and 50°C/25°C in the growth chamber suffered more severely in all traits up to mortality. Therefore,30/25°C treatment would be more valuable for high marketability due to increased plant height, leaf number, and dry mass compared to other treatments.

Published: April 2023

Abstract
Information on soil moisture is very important in activities cultivation of crops, especially in rainfed land which is very vulnerable to climate change. The need for a method for estimating soil water content is very urgent because of the amount of time and energy required by the gravimetric method. One way that can be applied is with Planetscope Imagery. Planetscope sensors are inexpensive so they are increasingly being used for science and environmental applications, including for land cover classification. The research was carried out on rainfed land, the slopes of Mount Lawu - Central Java, at different altitudes, in the highlands, the middle plains, and the lowlands, with descriptive explorative research method, using purposive sampling to obtain an image to determine the Color Digital Number value. The results of the color digital number are used for correlation and regression analysis to determine the relationship between the actual soil moisture content and the digital number on the Planetscope image. The T-test was used to determine whether there was a significant difference between the results of the actual moisture content and the predicted moisture content. The results showed that the accuracy of Planetscope imagery in predicting soil moisture content in the highlands, middle plains, and lowlands was 86.16%; 89.07%, and 95%. These results indicate the high accuracy of PlanetScope images in predicting soil moisture content in rainfed rice fields in the toposequence of Mount Lawu, Central Java.
Effect of a neurokinin 3 receptor-selective agonist administration on the embryos recovered from superovulated cows

Published: April 2023

Abstract
Superovulation (SOV) treatment of cows results in unovulated follicles and inconsistent quality of the recovered embryos. It has been demonstrated that luteinizing hormone (LH) secretion is suppressed during SOV treatment of cows, which may cause insufficient follicle development and variation in the development of recovered embryos and unovulated follicles. Pulsatile gonadotropin-releasing hormone/LH secretion is controlled by the activity of kisspeptin, neurokinin B and dynorphin (KNDy) neurons in the arcuate nucleus in many mammals. As neurokinin B promotes the activity of KNDy neurons, we hypothesized that senktide, a neurokinin B receptor agonist, has the potential as a therapeutic drug to improve the ovulation rate and quality of recovered embryos in SOV-treated cows via stimulation of LH secretion. Senktide was administered intravenously (30 or 300 nmol/min) for 2 h, beginning from 72 h after the start of SOV treatment. LH secretion was examined before and after administration, and embryos were collected 7 d after estrus. Senktide administration increased LH secretion in SOV-treated cows. The ratios of code 1, code 1 and 2, and blastocyst stage embryos to recovered embryos were increased by senktide (300 nmol/min) administration. Moreover, the mRNA levels of MTCO1, COX7C, and MTATP6 were upregulated in recovered embryos of senktide (300 nmol/min)-administered animals. These results indicate that the administration of senktide to SOV-treated cows enhances LH secretion and upregulates the expression of genes involved in mitochondrial metabolism in embryos, thereby improving embryo development and embryo quality.
