Authors: Ning Wanling , Wang Shiheng , Tang Hanqing , Wu Sichu , Huang XiaoSong , Liu Baiyan , Mao Yilin
Published: October 2023

Objective
Atrial fibrillation (AF) is one of the most common arrhythmias. At present, the treatment for patients with atrial fibrillation mainly includes oral anticoagulants (OACs). Studies have shown that OACs are associated with cognitive decline in patients with atrial fibrillation, but there is a lack of relevant evidence. This study used Bayesian network meta-analysis to investigate the effects of different oral anticoagulants on cognitive decline in patients with atrial fibrillation.
Method
We systematically searched the clinical studies of oral anticoagulants on patients with atrial fibrillation included in PubMed, Web of Science, Embase, and Cochrane library as of July 3, 2023. Use Cochrane's randomized controlled trial bias risk assessment tool and Newcastle Ottawa Scale (NOS) to assess the bias risk of the included studies. The main outcome measure was a decrease in cognitive function.
Result
A total of 10 studies were included, including two RCTs and seven RCSs, including 882847 patients with atrial fibrillation. Including 8 oral anticoagulants: VKAs, Warfarin, Aspirin, Clopidogrel, Dabigatran, Edoxaban, Rivaroxaban, and Apixaban. The results of the mesh meta-analysis showed that VKAs were superior in reducing the risk of cognitive decline in patients with atrial fibrillation compared to warfarin (OR=-1.19, 95% CI (-2.35, -0.06), P < 0.05) (Table 4). The top three in terms of probability of reducing the incidence of cognitive impairment in patients with atrial fibrillation with different oral anticoagulants are VKAs (87%), Rivaroxaban (62.2%), and Dabigatran (60.8%).
Conclusion
Based on the results of this study, VKAs may be the potential best intervention measures that can reduce the risk of cognitive decline in patients with atrial fibrillation. Due to the limitations of this study, more high-quality randomized controlled trials with large samples and multiple centers are needed in the future to provide more evidence.

The study took the northern area as the object of evaluation by geostatistical software, fuzzy integrated comprehensive evaluation method and potential ecological risk index. The evaluation results were affected by natural geomorphological factors.There were four land types in the area, with varying spatial distribution ratios, as follows,the construction zone type which accounted for 21% of area, the grasslands type which accounted for 32%, the arable land type which accounted for 46%, and the forest land type which accounted for 1%. The ecological risk evaluation index of the study area indicated a slight threat. Using the health risk evaluation model, the children's health risk index were found to be 4.9×10− 3～1.31×10− 2, while the adults' health risk index were 3.2×10− 3～1.13×10− 2. Children were roughly 0.5 times more susceptible to health risks than adults. Therefore, there should be sustained attention to the nitrate groundwater contamination in the study area.

Determining the targets of of licorice against postmenopausal osteoporosis: A drug target mendelian randomization study followed network pharmacology analysis
Authors: Shan Shan , Chen Yijie , Zhang Zhifen
Published: October 2023

Background
We aimed to examine the main active components and mechanism of action of licorice against postmenopausal osteoporosis (PMOP) using a network pharmacology approach.And we also use the drug target mendelian Randomization (MR) to estimated the association between protein targets and PMOP, osteoporosis.
Methods
The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform was searched for active ingredients and potential targets of licorice. Cytoscape 3.7.2 software was used to build a network between the active components of licorice and its targets. A protein–protein interaction network of the prospective targets of licorice for PMOP treatment was constructed. Enrichment studies using the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases were performed on the primary targets. Instrument variables obtained from eQTLGen stroage, the outcome data get from the FinnGEN and Bionbank Japan Project. Primary causal effect was estimated by inverse variance weighted. Leave-one-out analyses and co-localization were uesd to vertifited the driven effect of single nucleotide polymorphism.
Results
We identified 88 potent active compounds from licorice and the corresponding 226 targets of action and retrieved 2,271 osteoporosis-related genes. The main active components were quercetin, kaempferol, naringenin, formononetin, and 7-methoxy-2-methyl isoflavone; the relevant protein targets were RXRA, AKT1, PPARA, TNF, CYP1A1, F2, and STAT3. MR analyses suggested STAT3 has a positive association both with PMOP of European population (odds radio [OR] 1.27, 95% confidence interval [CI] 1.01–1.60) and osteoporosis of East Asian (OR 1.29, 95% CI 1.18–1.41).
Conclusions
The pharmacodynamic effects of licorice for PMOP are the result of multi-component, -target, and -pathway interactions. Licorice may affect the development of PMOP throughSTAT3 gene,tumor, lipid, and arteriosclerosis pathways; chemical carcinogenicity activation; and advanced glycation end products–receptor (AGE–RAGE) pathways, thus providing a scientific basis for using licorice against PMOP.
Newly discovered differences of reproductive traits between island and mainland plants support Baker’s law
Authors: Keller Barbara , Alther Barbara , Jiménez Ares , Koutroumpa Konstantina , Mora-Carrera Emiliano , Conti Elena
Published: October 2023

Background: Reproduction in angiosperms involves either one or two parents, through which selfed/cloned or outcrossed progeny is formed, respectively. Uniparental reproduction is advantageous when lack of mates and/or pollinators limits outcrossing opportunities. Baker’s law predicts that the capacity for uniparental reproduction should be enriched in habitats colonized via long-distance dispersal, such as volcanic islands. To test Baker’s law, we quantified variation of reproductive traits at multiple hierarchical levels and compared seed set after selfing and crossing experiments in both island and mainland populations of Limonium lobatum, a widespread species that Baker described as self-incompatible based on observations of stigma-pollen dimorphism in their flowers. In species with the type of pollen-stigma dimorphism that Baker detected in L. lobatum, pollen of one floral morph typically cannot fertilize ovules of the same floral morph.
Results: We discovered new variation and combinations of pollen-stigma traits never described before and determined that plants with such novel combinations were more common in island than mainland populations. We also documented, for the first time, a lack of correspondence between specific pollen-stigma combinations and pollen compatibility. Furthermore, the results of manual pollination experiments established that selfed seed-set was higher in island than mainland plants, while outcrossed seed-set was lower in island than mainland plants. Overall, more than 80% of all plants were self-compatible, while less than 20% were partially or entirely self-incompatible.
Conclusions: Contrary to previous descriptions by Baker, L. lobatumis a species that includes both self-compatible and self-incompatible plants characterized by both known and previously undescribed combinations of pollen-stigma traits. This type of variation was previously unknown in Plumbaginaceae and the lack of correspondence between pollen-stigma combinations was never described outside the highly variable species complex of Armeria maritima. Furthermore, island populations of L. lobatum harbor more plants with the newly discovered pollen-stigma combinations than mainland populations and are enriched in their capability for uniparental reproduction, corroborating Baker’s law. Our study establishes a link between variability of reproductive traits and capability of uniparental reproduction on islands, connecting research on reproductive and island biology.

The complete genome sequence of one rare actinobacteria Amycolatopsis sp. BCA−696 was characterized in this study. BCA−696 was previously reported as a biocontrol agent against charcoal rot in sorghum and a plant growth-promoting agent in sorghum and chickpea. The next-generation sequencing based whole draft genome of BCA−696 comprises of ~ 9.05Mb circular chromosome with 68.75% GC content. In total, 8,716 protein-coding sequences and 61 RNA-coding sequences were predicted, and the species-specific genomic features of Amycolatopsis sp. BCA−696 was analysed. Here we also report the Amycolatopsis sp. BCA−696 produces the glycopeptide antibiotic vancomycin that inhibits the growth of pathogenic gram-positive bacteria. Moreover, BCA−696 possesses 23 biosynthetic gene clusters (BGCs) that may be of biological importance. The comparative genomic analysis of BCA−696 and fourteen other strains of Amycolatopsis revealed a total of 3,627 core and 1,423 unique orthologous genes present in the genome. The number of unique genes ranged from 654 to 2557 across 15 strains of Amycolatopsis. Genome assembly of the BCA−696 also provided genes involved in key pathways related to plant growth promotion (PGP) and biocontrol traits such as siderophores, chitinase, and cellulase.

Published: October 2023

Objectives Pre-Vascularization of collagen membranes with autologous platelet concentrates is a standard procedure in oral and maxillofacial surgery. This study analyzed the possible interaction of an acellular collagen membrane of porcine origin (NM) with platelet-rich fibrin (PRF) regarding its rehydration protocol with differences in pH values and effect on angiogenesis.
Materials and methods NM was analyzed alone and combined with solid PRF by plotting or co-culturing with injectable PRF. Different media (venous blood, buffer solution with a fixed pH value of 7, saline solution, and injectable PRF) were used to analyze the influence on pH value during rehydration. Chorion allantois membrane assay (CAM) was applied to check pro-angiogenic effects after 24, 48, and 72 hours, followed by immunohistochemical analysis.
Results Rehydration in injectable PRF showed acidity over time (p < 0.05). A definite pro-angiogenic effect of NM alone was found regarding neo-vessel formation supported by the respective light microscopically analysis without significant differences to PRF alone (p>0.005). This pro-angiogenic effect could not be exaggerated when NM was combined with liquid/solid PRF (each p>0.005).
Conclusions Rehydration with liquid PRF of the collagen membrane results in acidity compared to a saline solution or patient’s blood. The significant pro-angiogenic potential of the membrane alone resulted in enhanced neo-vessel formation that could not be optimized with the addition of PRF.
Static and dynamic adsorption of arsenate from water by Fe3+ complexed with 3-aminopropyltriethoxysilane-modified carboxymethyl chitosan
Authors: Jiang Changjin , Zhang Shuang , Zhang Ting
Published: October 2023

Fe3+ complexed with 3-aminopropyltriethoxysilane (APTES)-modified carboxymethyl chitosan (CMC) named Fe-ACMC was synthesized by a one-step method at room temperature and pressure. The surface morphology and chemical structure of Fe-ACMC were characterized by SEM-EDS, XRD, BET, FT-IR, XPS, and ζ-potential. Both Fe3+ and APTES adsorbed onto the CMC surface. The optimum pH for arsenate [As(V)] adsorption was 3–9 with removal efficiency > 99%. The adsorption of As(V) onto Fe-ACMC could reach equilibrium within 25 min with the maximum adsorption capacity of 84.18 mg g–1. The pseudo-second-order model (R2 = 0.995) fitted well the kinetic data, while the Freundlich model (R2 = 0.979) well described adsorption isotherm of As(V) on Fe-ACMC. The co-existing anions (NO3–, CO32–, and SO42–) exhibited a slight impact on the As(V) adsorption efficiency, whereas PO43– inhibited As(V) adsorption on Fe-ACMC. The real applicability of Fe-ACMC (0.8 g L–1) was achieved to remove ca. 10.0 mg L–1 of As(V) from natural waters to below 0.05 mg L–1. The regeneration and reuse of Fe-ACMC for As(V) adsorption were achieved by adding 0.2 mol L–1 HCl, whereas the adsorption capacity decreased after 5 cycles. The main adsorption mechanism of As(V) on Fe-ACMC was attributed to electrostatic attraction and inner-sphere complexation between –NH2···Fe3+ and As(V). The dynamic adsorption of As(V) onto Fe-ACMC was investigated in a fixed-bed column. Thomas model was the most suitable model to elucidate the dynamic adsorption behavior of As(V). The loading capacity of Fe-ACMC packed column for As(V) was 47.04 mg g–1 at pH 7 with an initial concentration of 60 mg L–1, flow rate of 3 mL min–1, and bed height of 0.6 cm. The excellent performance of Fe-ACMC for adsorption makes it a good candidate for a wide range of applications.
Multiprojection Local Discriminant Analysis
Authors: Ma Jiajun , Zhang Shilong , Xu Fei , Hu Zhijuan
Published: October 2023

Linear discriminant analysis (LDA) is a critical technology for dimensionality reduction (DR). However, LDA still suffers from the following issues. One is that the total number of features available from LDA is limited to the number of classes minus one, which severely limits its application, especially for the problems where the dimension of the features is much higher than the number of classes. Another one is that LDA only preserves the global information of the data while ignoring the local structure of the data, which degrades the performance. To overcome these disadvantages, a multiprojection local discriminant analysis (MLDA) of calculating the discriminant features is proposed in this paper. Specifically, we first make a simple but crucial transformation for the optimization problem of LDA, and then propose a novel multiprojection convex discriminant analysis framework that can extract an unlimited number of features and avoid the small sample size problem. In addition, an auto-optimized graph technology is cleverly integrated into the discriminant analysis framework to exploit the local structure of data. As a result, enough more discriminative and structured features can be extracted. Since two variables need to be optimized simultaneously in the proposed methods, an efficient iterative optimization algorithm is introduced to solve the proposed MLDA. Extensive experiments on several benchmark data sets have demonstrated the effectiveness of the proposed method.

Application of wound dressings loaded with antimicrobial agents considered a viable option to reduce wound bacterial colonization and prevent infection, in order to improve the healing process. In this study, we developed an easy-produced chitosan sponge-like wound dressing containing a broad-host spectrum Escherichia phage BIM BV-67 as an antimicrobial component. This novel dressing was entirely composed of biologically safe and biocompatible materials, had a porous structure, was biodegradable, and exhibited a high swelling capacity. Atomic force microscopy of model layer-by-layer modified planar surfaces and scanning electron microscopy of chitosan sponges showed a non-oriented adsorption and low density of phage particles on chitosan surface. However, immobilized Escherichia phage BIM BV-67 maintained its infectivity and lytic activity. Phage-loaded chitosan sponges effectively inhibited growth of E. coli BIM B-984 G in both qualitative (agar diffusion) and quantitative (suspension) in vitro assays. Moreover, the dressings with bacteriophage retained bactericidal activity for 12 weeks when stored at 4°C. Furthermore, in vivo testing showed that topical application of phage-loaded chitosan sponges significantly reduced the number of E. coli BIM B-984 G cells in the wound and resulted in accelerated wound surface regeneration in infected rats compared to the use of pure sponges and no treatment. Based on these promising results, developed technology has potential as a platform for producing topical dressings with immobilized bacteriophages active against wide range of wound-infecting pathogens. In turn, this could promote the application of phage therapy in wound management.

Published: October 2023

Bacillus subtilis is a plant growth promoting bacterium that acts as a microbial fertilizer and biocontrol agent, providing benefits such as boosting crop productivity and improving nutrient content. It is able to produce secondary metabolites and endospores simultaneously, enhancing its ability to survive in unfavorable conditions and eliminate competing microorganisms. Optimizing cultivation methods for the production of B. subtilis MSCL 897 spores on an industrial scale requires a suitable medium, typically made from food industry by-products, and maintaining optimal temperature and pH levels to achieve high vegetative cell and spore densities with maximum productivity and yield. In this study, we demonstrate successful pilot-scale (100 L bioreactor) production of a biocontrol agent B. subtilis with good spore yields (1.5 x 109 spores/mL) and a high degree of sporulation (> 80%) using a low-cost cultivation media, which showed excellent antifungal activity (1.6–2.3 cm) against several phytopathogenic fungi. An improved methodology for inoculum preparation was investigated to ensure an optimal seed culture state prior to inoculation, promoting process batch-to-batch repeatability. Increasing the molasses concentration in the medium and operating the process in fed-batch mode with additional molasses feed, did not improve the overall spore yield, hence, process operation in batch mode with 10 g/L molasses is preferred. Results also showed that the product quality was not significantly impacted for up to 12 months of storage at room temperature.

Published: October 2023

The current study is a pioneering effort to create karyotypes and include comprehensive karyomorphological analysis of two wild species (M. sar-gharwalensisfrom Uttarakhand containing high protein content of 39.5% andM. axillarefrom Australia with significant characters, such as more pods/plant, a larger seed yield/plant, stress tolerance etc.) and one cultivated species (M. uniflorum) of horsegram. For genetic diversity study eight cultivated lines (VLG1, HPKM319, HPKM317, HPKM249, HPKM193, HPK4, HPKM191, HIMGANGA) along with wild species were analyzed with 50 SSRs primers. Cytogenetic markers like secondary constrictions, 45S rDNA and 5S rDNA were established in this study. Over 200 crossing attempts between cultivated and wild species resulted only six F1, which were sterile. The cause of the F1's sterility was identified by studying pollen morphology, meiotic anomalies, and chromosomal data. The phylogenetic tree was drawn from the molecular analysis using DARwin software. All results were in consonance with the other results yielded by Dendogram and Structure analysis. Dendrogram showed thatM. sar-gharwalensisis completely distinct from the cultivated lines, whereasM. axillarefound to be very close to them. HIMGANGA and HPKM193 lines of cultivated species exhibited more resemblance towardsM. axillareas compared to the other species. Molecular characterization and karyotypic studies markedM. axillareas the closest parent of the cultivated horsegram (M. uniflorum). These findings would be extremely beneficial in clarifying the phylogenetic relationships and extending the limited genetic base of the cultivated species of horsegram for further enhancing its nutritional and therapeutic properties.
Video alignment using unsupervised learning of local and global features
Authors: Fakhfour Niloufar , ShahverdiKondori Mohammad , Mohammadzade Hoda
Published: October 2023

In this paper, we tackle the problem of video alignment, the process of matching the frames of a pair of videos containing similar actions. The main challenge in video alignment is that accurate correspondence should be established despite the differences in the execution processes and appearances between the two videos. We introduce an unsupervised method for alignment that uses global and local features of the frames. In particular, we introduce effective features for each video frame using three machine vision tools: person detection, pose estimation, and VGG network. Then, the features are processed and combined to construct a multidimensional time series that represents the video. The resulting time series are used to align videos of the same actions using a novel version of dynamic time warping named Diagonalized Dynamic Time Warping(DDTW). The main advantage of our approach is that no training is required, which makes it applicable for any new type of action without any need to collect training samples for it. For evaluation, we considered video synchronization and phase classification tasks on the Penn action dataset \citep{penn}. Also, for an effective evaluation of the video synchronization task, we present a new metric called Enclosed Area Error(EAE). The results show that our method outperforms previous state-of-the-art methods, such as TCC \citep{TCC}, and other self-supervised and weakly supervised methods.

Background: Motor cognitive risk syndrome (MCR) is a pre-dementia and disability state combining objective slow walking speed and subjective cognitive complaints (SMCs). To explore the risk factors and the association between 8-hydroxy-2’-deoxyguanosine (8-OHdG) and motor cognitive risk syndrome (MCR) in Chinese community-dwelling elderly people.
Methods: A total of 1312 participants were involved in this study based on the data of the Rugao Longevity and Aging Study (RuLAS). The MCR was characterized by subjective memory complaints (SMCs) and slow walking speed. The SMCs were defined as a positive answer to the question ‘Do you feel you have more problems with memory than most?’ in a 15-item Geriatric Depression Scale. Slow walking speed was determined by one standard deviation or more below the mean value of the patient’s age and gender group. The plasma of 8-OHdG were measured by a technician in the biochemistry laboratory of the Rugao People’s Hospital during the morning of the survey.
Results: The prevalence of MCR was 7.9%. After adjusting the other covariates, the elder (OR 1.057, 95% CI 1.010–1.106; p= 0.018), cerebrovascular disease history (OR 2.155, 95% CI 1.206–3.850; p= 0.010), and elevated level of 8-OHdG (OR 1.007, 95% CI 1.002–1.012; p= 0.003) showed obvious relevance to MCR.
Conclusions: This study indicated These results may suggest that the elevated 8-OHdG was associated with the increased risks of MCR in elderly community.

Published: October 2023

Recent advancements in deep learning have led to significant improvements in driving perception. However, perceiving the environment accurately during risky situations like fog remains a major challenge. Existing methods for detecting foggy atmospheres struggle with both recognition speed and accuracy. In this study, we propose an object discovery network specifically designed for driving in foggy environments, utilizing a modified version of YOLOv5. Our approach involves building a mist detection network based on a modified ResNet-50 model. To address the lack of features in foggy scenes, we introduce a new feature enhancement module (FEM) and employ the skip attention mechanism. These additions allow the recognition network to focus on the most relevant features in foggy scenes, improving overall performance. Experimental results demonstrate that our suggested foggy multi-target recognition network outperforms the original YOLOv5 in terms of both accuracy and speed. When evaluated on the MS COCO vehicle dataset, our network achieves an impressive accuracy of 81.8%, showcasing its superiority over the original YOLOv5. This advancement in foggy environment perception holds great promise for enhancing driving safety and efficiency. Keywords: accuracy, deep learning, driving perception, foggy environment, mist detection, object discovery, recognition speed, ResNet-50, skip attention, YOLOv5.

Published: October 2023

Compressibility and pressure-induced structural evolution of kokchetavite, the hexagonal polymorph of KAlSi3O8, has been studied up to 11.8 GPa using synchrotron single-crystal X-ray diffraction. Two phase transitions were observed at pressures of ~0.3 and 10.4 GPa. Kokchetavite-I (as-synthesized, P6/mcc) transforms into kokchetavite-II with the P6c2 space group. Kokchetavite-II → kokchetavite-III phase transition at ~10.4 GPa is accompanied by a change of symmetry to probably orthorhombic. After pressure release, kokchetavite reverts to the initial single-crystal state with P6/mcc space group. A second-order Birch-Murnaghan equation of state was calculated for phase kokchetavite-II with coefficients V0 = 1486(3) Å3, K0 = 59(2) GPa.

Published: October 2023

Population growth increases the demand for world food needs. Meanwhile, the agricultural sector’s challenges are increasing due to reduced agricultural land, climate change, and natural disasters. The covid-19 pandemic teaches us the importance of precision agriculture to produce optimal food products with minimal input. This study aims to introduce low-input farming practices at the household scale. Low-input farming (LIF) was chosen because its production costs are relatively low with low inputs. Low-input farming is an agricultural practice that maximizes the use of land resources, ensures the achievement of profits, minimizes environmental damage and negative impacts, and prevents adverse effects on health. The study was carried out in partnership with women farmer groups. This study introduced three main programs to support food self-sufficiency at the household scale: hydroponics, aquaponics, and training in processing processed food products made from fish. The selection of program types was determined based on the community's needs following the community's economic capacity to provide inputs in cultivating food crops on a household scale. Intensive assistance was also carried out by a team of experts from agronomy, environmental science, and food technology to ensure the successful implementation of the program. In addition, agricultural inputs with hydroponics in planting media, seeds, and fertilizers are available at low and affordable prices with optimal yields. Meanwhile, for aquaponics, the cultivation of vegetable and fish were introduced in one cultivation medium. The selected plants and fish were species that can grow easily in various climatic conditions and were widely consumed by the community. The training on processing processed food products from fish continues the other two programs. This program increases the knowledge of farmer groups to process fish so that it can increase the added value of fish harvests as well as for household consumption.

Through the participation of local communities in the preservation of mangrove forest ecosystems, an attempt is being made to prevent further damage to the mangrove environment and recover from any damage already caused. The mangrove forests along the shore of Kampung Laut, most notably those located in the Ujung Alang Village, are kept in pristine form because of the numerous and varied types of mangrove plantation activities that are carried out there. The local people are currently utilizing mangrove plants as a source of food (certain parts of the plant) and building materials (the stems). On the other hand, its use as a natural dye source is not yet common enough to be considered a significant industry. So, the mangrove forest ecosystem can be protected through the Sustainable Utilization of Mangrove Forests for the Production of Natural Dyes with a Zero Waste System, which includes: (1) the preparation and completion of a natural dye production unit based on the right technology for Kampung Laut village; (2) the preparation and completion of the production unit to produce charcoal briquettes and liquid smoke from mangrove waste as a new and innovative use for mangrove waste; and (3) the preparation and completion of the production unit to produce naturally.

The abundance of manure can be used as a local commodity that has the potential to be a business opportunity for local communities through youth farmer groups. At present, the abundance has not been optimally utilized. Its use is only sown directly into the land, which can have several implications, including reduced nutrient content due to volatilization and lack of practical use. Managing manure into packaged fermented organic fertilizer makes its use more practical, effective, and efficient. The increase in the use of fermented organic fertilizers also can reduce agricultural production costs, such as purchasing chemical fertilizers. The purpose of this program was to assist Ngudi Boga's youth farmer group in managing manure into packaged fermented organic manure, which is marketable and partly used by themselves. Aerobic composting was applied. Raw materials, including manure, foliage, and other local organic matter, were used. The fertilizer samples were analyzed for nutrient content. It has produced 375 packs (5 kg/pack) of ready-to-use fermented organic fertilizer, equivalent to ± 1.76 tons. It was >75% of production sold by the limited local markets. Future improvement efforts related to increasing the capacity of grinding machines and developing a profit-sharing system with the village community need to be carried out.

Budikdamber is the acronym for “budidaya ikan dalam ember”, an Indonesian term for a small-scale aquaponic system in a plastic bucket. This equipment is famous for its compact size and easy implementation to cultivate fish in households, especially for those with limited space resources. Budikdamber can be seen as the proper solution to support one of Kulon Progo’s critical programs to reduce its poverty rate. The number of animal protein intake in each local community family is one indicator to measure the poverty rate. Hence, Budikdamber allows lower-income families to cultivate fish in their houses to fulfill their animal protein needs. This paper reported the community-based activity to design and implement Budikdamber of giving guidance to low-income families. The general problems of implementing Budikdamber for the community service program were the low fish productivity and sustainability of the people using granted Budikdamber. This program introduced Budikdamber, equipped with a water circulation system to improve fish productivity, hopefully increasing people's interest in using Budikdamber. The design included a solar panel to prevent additional maintenance costs of required electricity for Budikdamber—which has been successfully manufactured into a prototype by the student community service program. A series of activities (including socialization, operation tutorial, and a hearing from Kulon Progo district’s stakeholders) were conducted to bring the design and prototype to Tanjungharjo, Nanggulan, Kulon Progo local community.

An increasing number of lectures in higher education are being held online. This study aimed to establish the nature and frequency of external distractions during online learning and to obtain students' opinions on whether distractions affected their study performance. We, therefore, conducted a survey with university students about external distractions during online learning and students' attention engagement using the adult ADHD (Attention Deficit-Hyperactivity Disorder) Self-Report scale. Eighty response sheets were collected, half of which were from Indonesian students in Indonesia and a half from Japanese students in Japan. The frequency of distractions for this study is described as the number of incoming visual, auditory, or audio-visual notifications from electronic devices, such as pop-up windows of software updates, battery warnings, chats, or e-mails. A number of distractions from other external events was obtained as well. From the survey, we discovered that about one-third (25-37%) of 80 students reported that their study performance was affected frequently (“often” or “always”) by external visual, auditory, and audio-visual distractions from electronic devices. Moreover, a significant correlation was obtained between the perceived frequency of these distractions and the students' attention scores: Low attentional engagement was accompanied by a relatively high number of perceived distractions. Although online learning fulfills the need for social distancing and may make lectures or meetings easier to organize, it is not ideal for all students, given that many thought their study performance was affected by external distractions.

The amount of organic and inorganic waste which has not been appropriately managed has become a global problem. The zero-waste system can then be a solution to waste problems. The zero-waste system must be implemented to protect areas with valuable natural and cultural resources. For instance, it could be implemented in the ecotourism area of Kebonagung village, Imogiri District, Yogyakarta. This educational program aims to provide understanding and upgrading skills related to the zero-waste system by creating a waste-free ecotourism area. This program will be conducted from December 2021 to September 2022 through socialization, waste treatment training and application, and evaluation monitoring. This program resulted in the socialization implementation of inorganic waste processing, liquid organic fertilizer, home-grown vegetables, Mina-padi (rice-fish farming), biogas, and Black Soldier Fly (maggot) larvae cultivation—which is the main focus of this program. Waste system training and application are carried out by turning plastic bottles into crafts, building Omah Maggot (a maggot breeding ground), also maggot cultivation training, monitoring, and guidance. This maggot cultivation could accommodate up to four kilograms of organic waste per day, along with a half kilogram of harvested maggot that could be harvested as fish seed. The remaining organic waste, known as kasgot, can be used as plant fertilizer. From evaluation to in-depth interviews, it is known that the community understands the zero-waste system concept and application. Yet, they lacked the organic waste handling experience for maggot, and no group yet can handle inorganic waste processing. From the results obtained, it can be concluded that this program received positive support and responses from the community that has gained knowledge and skills related to a zero-waste system toward creating a waste-free area.

Mangrove conservation in Indonesia has progressed from planning, and implementation to monitoring, supported by the efforts of the government and non-governmental groups. Mangrove rehabilitation and conservation is an effort to restore the function of degraded mangrove forests and increase the potential for suitable land to be planted with mangroves. Mangrove rehabilitation efforts in Pedaleman Village, Tanara Sub-district, have created a significant mangrove ecosystem in the surrounding area, including the arrangement and restriction of conservation areas with fishpond business areas. Rehabilitation efforts can be realized by selecting suitable site of mangrove planting locations as part of conservation planning. Site selection by visual interpretation method using remote sensing imagery from Planetscope satellite has provided a synaptic overview of land use in the coastal and estuary area of Pedaleman Village. This site selection results in potential mangrove planting areas and non-potential areas. More than 50% of the coastal area of Pedaleman Village is considered conducive for mangrove seedling planting planning. Of this percentage, there are some land uses of ponds and vacant land, most of which can be converted into part of the mangrove forest area.

In Indonesia, the decline of the calf birth rate affects the cattle population. One way to increase the population and birth rate of cattle can be done through artificial insemination. However, using artificial insemination devices does not guarantee the accuracy of the cattle’s heat period. An artificial insemination device integrated with an endoscopic camera combined with photo, video, and temperature capture methods is needed to carry out the stages before and after the placement of sperm semen on the ovaries, namely the heat period and pregnancy detection. The design of this artificial insemination device, known as the IB-G2, is emphasized so that insemination officers are more focused by positioning the screen on board. The IB-G2 was successfully made with a 1.4 GHz processor specification, 1GB memory, 3.5" 320x480 Dots color touch screen LCD, 640x680p camera, and a temperature sensor range -55 to 125 °C. The IB-G2 is expected to contribute to helping inseminators in particular and farmers in general to catalyze the cattle population increase.

Beach tourism is identical to coconut. Almost all beach tourists will look forward to enjoying fresh coconut water under the hot beach atmosphere. High coconut consumption in tourist areas greatly benefits the economy of traders in tourist areas. On the other hand, it creates a problem due to increased coconut waste. Coconut waste is large and difficult to decompose, resulting in a buildup that could disrupt coastal tourism. Goa Cemara Beach in Bantul, Yogyakarta, is one of the areas affected by coconut waste accumulation, hence warranting proper management of coconut shell waste. Coconut shell waste Management is expected to be a new source of income for the local community. Community service activities are carried out to apply coconut waste processing technology. This technology is carried out to overcome the problem of accumulation of waste and utilize waste as a support for sustainable agriculture. Applying this waste treatment technology involves two community groups, namely the “Pantai Goa Cemara” tourism awareness group and the “Tani Raharjo” farmer's group. Each group has a synergistic role in the processing and utilization of waste. The Goa Cemara Beach tourism awareness group, processes the destruction of coconut shell waste with a mill. The crushed coconut shell waste will produce small pieces. Sorting the crushed coconut waste will produce two forms, namely cocopeat, and cocofiber. Laboratory tests are carried out to see the content of cocopeat and the safe amount that can be applied to agriculture. Laboratory results showed organic matter 19.51-28.70%, Nitrogen 0.69-0.88%, Phosphorus 0.40-0.58%, Potassium 0.26-0.33%, and pH 7.66-7.95 depending on the age of the waste. Community service activities are carried out to utilize cocopeat to become an environmentally friendly seedling medium. Seedling media with cocopeat printed in squares can sow plant seeds. This box media is often called a soil block and does not require small plastic pots for seeds. Thus, it can reduce plastic waste on agricultural land. In addition, the utilization of processed coconut shell waste can support sustainable agriculture.
