Authors: Salimah A’isyah , Simatupang S , Christian R , Hasan M F R , Agung P A M 
Published: December 2023

Abstract
Clayshale soil was found 5 meters below ground level in the Hambalang area. The fragility of clay shale soil results in clay shale soil being rarely used in construction needs. The physical condition of clayshale is not optimal when it is dry and also when it is mixed with water. This research is carried out so that the cohesion value and shear strength in the clayshale is close to perfection with the stabilization process. Disturbed sampling was carried out in the Hambalang area, providing that the granules passed the 4mm filter. Tests carried out to obtain soil parameters include physical properties testing and mechanical properties testing. Based on the results of laboratory tests, the original clayshale soil has a plasticity index (IP) value of 27.07%, so clayshale soil included CL (Clay-Low plasticity) according to the USCS category. The use of Portland pozzolan cement in this study is because it has high resistance to salts and sulfuric acid. Mixing of PPC cement test materials was carried out to determine the optimal cohesion value and shear strength by mixing 5%,8%, and 11% of clayshale weight per sample. The addition of cement variations can increase the specific gravity value of the soil and the optimum moisture content, but it can reduce the dry weight value of the soil and the value of the plasticity index on clayshale soils. The cohesion values and soil shear strength obtained after Triaxial UU testing on samples with the addition of Portland pozzolan cement (PPC) increased; however, the increase that occurred was varied and significant at the time of the PPC cement mixture.
Building Envelope Performance to Achievement of Energy-Efficient Buildings : a case study analysis in Ulil Albab Mosque Yogyakarta
Authors: Hendrawati D , Arientaka M Z 
Published: December 2023

AbstractThe performance of the building envelope is one of the most important in energy-efficient buildings. As the outermost layer, the building envelope will be very decisive for heat transfer from outside to inside the building. The performance of the building envelope in heat transfer refers to as the Overall Thermal Transfer Value (OTTV). OTTV measures the average heat gain into the building through the building envelope. It is a measure widely adopted in many countries to improve the design of energy-efficient buildings. The OTTV value strongly influences the ratio of transparent openings on the building facade. The size of the transparent opening will affect the inclusion of natural lighting in the building. This study aims to see how closely the relationship between the OTTV value and the achievement of natural lighting in buildings according to standards. The values used as success standards are the GBCI and SNI parameters. This research expects to provide a reference for existing buildings to improve building performance, especially for energy efficiency. This study uses a simulation method with OTTV worksheets and DIAlux Evo calculations. The mosque chooses to be a case study because the mosque is a building that has a distinctive orientation. In this research, Ulil Albab mosque, Yogyakarta, for the case study. For the location of Yogyakarta, the Qibla direction is azimuth direction 294° 42′ 39.894″ (Northwest) from Yogyakarta, where the radiation factor value is the largest. The results of this study indicate that the OTTV value can follow the standard by lowering the percentage of WWR in a facade with a high radiation factor value. Still, a WWR that is too small can result in natural lighting being unable to enter the room. In this building, the most efficient thing to do is replace the transparent material with one with better thermal properties.
Proanthocyanidins-Rich Fraction of Tamarindus Indica Maintained Redox Status of Environmental Toxicant-Induced Genotoxicity in Drosophila Melanogaster
Authors: Mohammed Jaafaru Sani , Yusuf Jibril Habib 
Published: December 2023

Abstract
Proanthocyanidin, a bioactive polyphenolic component of tamarin (Tamarindus indica L.), offers neuroprotective benefits with insufficient scientific evidence. This study evaluated the behavioral and molecular effect of proanthocyanidin-rich fraction on the gene expression level of antioxidant and aging enzymes in Drosophila melanogaster. The fruit flies were fed with the fraction at 1.5 and 2.5 mg/g diet for seven days, followed by exposure to 0.1 µg/g diet lead oxide for equivalent days. Negative geotaxis and survival assays were conducted on the flies. The expression level of phase II antioxidant enzymes and acetylcholinesterase were evaluated using rt-PCR to assess proanthocyanidin’s protection level and mechanism in Pb-induced neurotoxic D. melanogaster. The results show that the proanthocyanidins-rich fraction enhanced locomotor activity and the rate of emergence of flies even in the presence of eco-toxicant. The fraction also mitigated the harmful effect of Pb via the activity of catalase and superoxide dismutase, as evidenced by the increase in the expression levels of the catalase and SOD genes in the noxious environment. Thus, the study provides insights into understanding the neuroprotection mechanism of proanthocyanidins-rich fraction against lead-induced neurotoxicity in D. melanogaster, which could be translated to humans when explored further.

Abstract
Indonesia’s nationally determined contributions (NDC) outline ambitious emission reduction targets, with the forestry and other land use (FOLU) sector expected to play a significant role in achieving these goals. This study estimates soil carbon stock in conservation areas covering mineral and peat soils. A total of 72 sample plots in Bukit Tigapuluh National Park (NP), Kutai NP, and Sebangau NP were established for soil sample collections. This study found that the highest organic content in mineral soil is at 0-5 cm depth, accounting for 3.54% in Bukit Tigapuluh NP and 2.72% in Kutai NP. The carbon stocks of mineral soil in Bukit Tigapuluh NP and Kutai NP at 0-30 cm depth are 43.17 tons C ha-1 and 56.77 tons C ha-1, respectively. Meanwhile, the carbon stock in peat soil in Sebangau NP at 400 m depth is 2,155.63 tons C ha-1, 43-fold more significant than the carbon stock in mineral soil. This study underscores the significance of soil carbon in Indonesia’s climate mitigation. It highlights the opportunity to refine emission estimates from the FOLU sector by adding a soil carbon pool to calculate the emission factor.

Published: December 2023

Abstract
Groundwater, a crucial resource for human needs and ecosystems, needs help ensuring its availability and quality in different regions around the globe due to overuse and exclusive access. Assemblage Thinking (AT), introduced by Deleuze and Guattari, offers a lens to unravel complex socio-ecological dynamics in groundwater governance. In most studies centered around governance, particularly concerning groundwater, researchers find themselves confined within a linear and structural viewpoint regarding the interactions among actors. This paper recommends using AT to analyze groundwater regimes’ socio-ecological dynamics and conflicting interests. AT is suitable for hybrid governance frameworks, encompasses dynamic and evolving processes rather than static conditions, and recognizes the impact of material objects on governance, including technology, policy, strategies, geohydrological, and spatial factors on groundwater access. AT will examine how human agency, biophysical elements, and social dynamics affect groundwater access, distribution, and use. Despite several challenges, AT is a promising holistic framework for understanding groundwater sustainability in a changing climate.

Abstract
The trend of natural food products free from synthetic additives has been experiencing rapid and dynamic growth in the global food industry. Nanocarotenoid-encapsulated compounds have been developed to increase stability, solubility, and industrial applications, especially for the design of carotenoid delivery systems and improving their bioavailability. This study aims to apply carotenoid nanoencapsulation technology from gnetum peel as an alternative food nutrient fortifier product. Nanoemulsion was prepared by homogenization using ultraturrax (11,000 rpm) combined with ultrasonication (1-3 h). The best nanoemulsion formulation was obtained from 1-hour sonication, showed by a minor diameter of the nanoparticles (99.54 ± 0.03 nm) and a low value of the polydisperse index (0.37 ± 0.03). The color properties and encapsulation efficiency of maltodextrin were also characterized. The greater the concentration of maltodextrin encapsulating material added, the better the carotenoid nanostructure. The higher percentage of maltodextrin influenced the color parameter.

Abstract
This article aims to explore the Optimization of Public Green Open Spaces as an Effort to Preserve the Environment in Klungkung Regency, Bali. The research in this article will use normative legal research methods with an analytical and descriptive nature. The study found that Optimizing the amount of green open space is very important for the surrounding environment and public health. Several factors cause obstacles in arranging green open spaces in Klungkung City. One of them is the limited ability of the Klungkung City Government to obtain green available space land. In addition, limited funds are also a factor affecting the Klungkung City Government’s ability to open green spaces. In addition, the lack of comprehensive planning from the Klungkung City Government in managing the available land to be used as green open space is also an obstacle. Collaborative efforts among government, communities, and the private sector are essential for successful implementation. The application of this approach contributes to the overall improvement and preservation of the environment, leading to a more sustainable future.

Published: December 2023

Abstract
The rapid growth of the textile industry, while bringing positive impacts, also brings negative effects related to the increasing amount of wastewater generated. Poorly managed wastewater can potentially create adverse effects on human health and the environment. This study evaluates the hybrid mesh filter bioreactor (MFBR) performance for textile wastewater treatment. The bioreactor was operated with a nylon mesh filter having 37 µm pore size under intermittent aeration with aeration on/off durations of 1/1 hour. Wastewater influent was degraded by microorganisms attached to biofilm carriers and filtered by an external filtration tank. The process performance was evaluated under varying concentrations of COD (600–1200 mg/L). The stable operation was achieved for around 60 days with 88.4-94.8% turbidity removal and a flux value of 102±15 L/m2·hour. Although high COD removal was observed (89.4-92.1%), only 14.3-25.2% color removal was achieved in hybrid MFBR under hydraulic retention time (HRT) of 4-8 hours.

Published: December 2023

Abstract
The current dynamics pose a number of primary tasks for society and the state, related both to the issues of accelerating economic growth and taking into account regional specifics in terms of increasing the requirements for ensuring the sustainability of socio- economic development strategies (SED). This requires ensuring the rational use of regional resources, including the need to maintain energy security (ES) of territories and environmental (EnM) protection. This article studies the interrelationships between the regions’ RP and the main factors of their sustainability: ES and the state of EnM. The purpose of the study is to analyze the impact of ES and the state of EnM on the RP regions in the process of their SED, taking into account the state of sustainability from the strategic perspective. The methodological basis of the study is based on the use of the comparativist approach, which allowed us to consider the factor states of regional sustainability through comparative analysis in order to select common characteristics that affect the RP state. As a result, the authors have formed models aimed at determining the relationship between sustainability factors and RP regions.

Published: December 2023

AbstractReducing the cost of electricity to improve production efficiency is one of the urgent tasks. Nowadays, the rapid development of Neodymium rare earth (NdFeB) permanent magnet technology has promoted the creation of high-efficiency motors to replace low-efficiency induction motors to save electricity. One of them is a line-start permanent magnet synchronous motor (LSPMSM). The permanent magnet configuration significantly affects the operating characteristics of the LSPMSM, such as working current characteristics, pulsating torque, working efficiency, and starting speed. The content of the article focuses on investigating and evaluating some permanent magnet configurations affecting the working characteristics of the LSPMSM based on the finite element method through Ansys/Maxwell software. The research results are suggested for the design and manufacture of LSPMSM used in mining to save electricity.
The Athenian Working Class
Authors: van Wees Hans 
Published: December 2023

AbstractThis chapter looks at those Athenians who were ‘working-class’ in the sense that they derived part or all of their livelihood by performing wage labour. It argues that that about 90 per cent of Athenians were in this category around 600 bce, and that most of them worked under highly exploitative conditions for a wage of only one-sixth of the crops they cultivated on their employers’ farms. Economic growth and social reform in the sixth century meant that a substantial ‘middle class’ of independent working producers emerged and that in classical Athens only about 55 per cent of citizens were still reliant on wages, now earned from casual or seasonal labour. Contrary to recent claims that wage labour was exceptionally well rewarded in classical Athens, this chapter argues that the Athenian working class continued to earn only a bare subsistence.
Hostile: accurate decontamination of microbial host sequences
Authors: Constantinides Bede , Hunt Martin , Crook Derrick W 
Published: December 2023

Abstract

Motivation
Microbial sequences generated from clinical samples are often contaminated with human host sequences that must be removed for ethical and legal reasons. Care must be taken to excise host sequences without inadvertently removing target microbial sequences to the detriment of downstream analyses such as variant calling and de novo assembly.

Results
To facilitate accurate host decontamination of both short and long sequencing reads, we developed Hostile, a tool capable of accurate host read removal using a laptop. We demonstrate that our approach removes at least 99.6% of real human reads and retains at least 99.989% of simulated bacterial reads. Using Hostile with a masked reference genome further increases bacterial read retention (≥99.997%) with negligible (≤0.001%) reduction in human read removal performance. Compared with an existing tool, Hostile removes 21%–23% more human short reads and 21–43 times fewer bacterial reads, typically in less time.

Availability and implementation
Hostile is implemented as an MIT-licensed Python package available from https://github.com/bede/hostile together with supplementary material.
Conformalized survival analysis with adaptive cut-offs
Authors: Gui Yu , Hore Rohan , Ren Zhimei , Barber Rina Foygel 
Published: December 2023

Summary
This paper introduces an assumption-lean method that constructs valid and efficient lower predictive bounds for survival times with censored data. We build on recent work by Candès et al. (2023), whose approach first subsets the data to discard any data points with early censoring times and then uses a reweighting technique, namely, weighted conformal inference (Tibshirani et al., 2019), to correct for the distribution shift introduced by this subsetting procedure. For our new method, instead of constraining to a fixed threshold for the censoring time when subsetting the data, we allow for a covariate-dependent and data-adaptive subsetting step, which is better able to capture the heterogeneity of the censoring mechanism. As a result, our method can lead to lower predictive bounds that are less conservative and give more accurate information. We show that in the Type-I right-censoring setting, if either the censoring mechanism or the conditional quantile of the survival time is well estimated, our proposed procedure achieves nearly exact marginal coverage, where in the latter case we additionally have approximate conditional coverage. We evaluate the validity and efficiency of our proposed algorithm in numerical experiments, illustrating its advantage when compared with other competing methods. Finally, our method is applied to a real dataset to generate lower predictive bounds for users’ active times on a mobile app.

Published: December 2023

Abstract
Repetitive transcranial magnetic stimulation (rTMS) and cognitive training for patients with Alzheimer’s disease (AD) can change functional connectivity (FC) within gray matter (GM). However, the role of white matter (WM) and changes of GM–WM FC under these therapies are still unclear. To clarify this problem, we applied 40 Hz rTMS over angular gyrus (AG) concurrent with cognitive training to 15 mild–moderate AD patients and analyzed the resting-state functional magnetic resonance imaging before and after treatment. Through AG-based FC analysis, corona radiata and superior longitudinal fasciculus (SLF) were identified as activated WM tracts. Compared with the GM results with AG as seed, more GM regions were found with activated WM tracts as seeds. The averaged FC, fractional amplitude of low-frequency fluctuation (fALFF), and regional homogeneity (ReHo) of the above GM regions had stronger clinical correlations (r/P = 0.363/0.048 vs 0.299/0.108, 0.351/0.057 vs 0.267/0.153, 0.420/0.021 vs 0.408/0.025, for FC/fALFF/ReHo, respectively) and better classification performance to distinguish pre-/post-treatment groups (AUC = 0.91 vs 0.88, 0.65 vs 0.63, 0.87 vs 0.82, for FC/fALFF/ReHo, respectively). Our results indicated that rTMS concurrent with cognitive training could rewire brain network by enhancing GM–WM FC in AD, and corona radiata and SLF played an important role in this process.
