Published: November 2024

Coconut fiber or coir is the outer part of the coconut fruit that is often considered as waste after the meat and water are extracted. Without proper processing, discarded coconut fibers will accumulate in the surrounding environment and creating a number of environmental problems. This community service activity aims to increase the knowledge and skills of the students through training in processing coconut fiber waste into cocopeat using a chopping machine. This cocopeat product can be used as an organic planting medium. This training was held at the Al Mimbar boarding school in Jombang, East Java, which can create an alternative source of income for the boarding school and foster environmental awareness among students. The methods used in this training include socialization and hands-on practice in making cocopeat. The results of this activity show that the students are increasingly aware of the environment, are able to process coconut fiber waste into quality cocopeat, and understand the economic value of the product as well as the market potential that can be utilized by the pesantren to get additional sources of funding from the sales of cocopeat. Thus, this program can be the first step for pesantren in developing sustainable environment-based businesses, as well as making a positive contribution to improving the local economy.Keywords: ecopreneurship; coconut fiber; cocopeat Abstrak: Serabut kelapa atau sabut kelapa adalah bagian luar dari buah kelapa yang sering dianggap sebagai limbah setelah diambil daging dan airnya.

Penggunaan perangkat radio portabel pada gelombang VHF (Very High Frekuensi) merupakan hal yang lazim dilakukan oleh tim-tim SAR untuk mengkoordinasikan kegiatannya di lapangan. Kendala utamanya adalah perangkat ini adalah daya jangkau yang rendah akibat penggunaan daya pancar yang rendah disamping sifat dari gelombang VHF sendiri yang mensyaratkan kondisi LOS (Line Off Side – Pandang Langsung)
Sebagai mitra kegiatan Ipteks bagi Masyarakat kali ini, RAPI (Radio Antar Penduduk Indonesia) Lokal Lawang Kabupaten Malang dan CBAT (Community Based Assesment Team) AmpelGading – SATGANA PMI Malang sering kali mengikuti kegiatan sosial kemanusiaan khususnya yang berkaitan dengan penanganan masalah bencana alam. Mereka umumnya menggunakan perangkat radio portable pada gelombang VHF untuk berkomunikasi dengan sesama anggota maupun dengan markas pusat. Kendala utama penggunaan perangkat ini (sebagaimana uraian sebelumnya) adalah masalah jarak jangkau yang terbatas. Untuk mengatasi kesulitan ini dapat digunakan 2 (dua) cara, yaitu: menggunakan perangkat dengan daya yang lebih besar atau menggunakan perangkat pancar ulang. Penggunaan perangkat dengan daya yang lebih besar jelas tidak memungkinkan untuk digunakan pada personal yang terus bergerak sehingga pilihan penggunaan Repeater (Pancar Ulang) untuk menunjang komunikasi adalah merupakan pilihan yang lebih tepat.
Kegiatan pengabdian masyarakat bidang Ipteks bagi Masyarakat yang dilaksanakanini adlah suatu kegiatan pengabdian kepada masyarakat yang menghasilkan luaran berupa perangkat Repeater Portabel. Repeater adalah perangkat yang dapat melakukan pemancaran ulang terhadap informasi yang diterima dengan daya yang lebih besar. Dan disebut portable karena perangkat ini dapat dipindahkan dengan mudah untuk mendapatkan daerah layanan yang lebih luas.
Perangkat portable repeater yang dihasilkan berukuran mini yaitu berukuran sekitar 30 x 17 x 22 cm (panjang x lebar x tinggi) dengan catu daya berupa aki sepeda motor. Dalam penggunaannya, portable repeater ini cukup diletakkan di atas pohon/tiang/gedung yang memiliki posisi lebih tinggi daripada pengguna radio amatir bergerak yang lainnya dan dapat bekerja secara kontinyu selama 8 (delapan) jam.

IntroductionThis study examined the impact of biochar application on agricultural productivity and greenhouse gas emissions in irrigated regions of northern Xinjiang. The objective of this study was to assess the impact of nitrogen fertilizer and biochar levels on soil respiration rate, enzyme activity, and spring wheat yield.Materials and methodsThe experiment employed a randomized block design comprising two nitrogen fertilizer levels (N1: 300 kg·hm-2 and N2: 255 kg·hm-2) and four biochar levels (B0: 0 kg·hm-2, B1: 10×103 kg·hm-2, B2: 20×103 kg·hm-2, and B3: 30×103 kg·hm-2). This resulted in eight groups (N1B0, N1B1, N1B2, N1B3, N2B0, N2B1, N2B2, and N2B3), each replicated three times.Results and discussionThe findings indicated that the N2B2 group exhibited a reduction in soil CO2 emissions, with a cumulative decrease of 4.42% in CO2 emissions compared to the N2B0 control. The application of biochar and/or nitrogen fertilizer, particularly in combination, was observed to increase soil urease, sucrase, and catalase activities. The N2B2 group exhibited a spring wheat yield of 8301.35 kg·hm-2, representing a 22.1% increase over the N1B0 group. This improvement was attributed to the capacity of biochar to regulate soil water content variability, stabilize soil aggregate composition, mitigate organic carbon mineralization, and reduce farmland carbon emissions. Furthermore, biochar’s nitrogen fixation provided essential nutrients for soil microorganisms, thereby enhancing enzymatic reactions and promoting crop growth.ConclusionIn conclusion, the N2B2 regime was determined to be the optimal approach for spring wheat cultivation in irrigated regions of northern Xinjiang, resulting in enhanced crop productivity and the mitigation of carbon emissions. Nevertheless, further investigation of its long-term impact on farmland is recommended.

ObjectiveThis study aims to summarize the clinical experience of using Hem-o-lok clips for the closure of the left subclavian artery (LSA) stump in patients with acute Stanford type A aortic dissection.MethodsClinical data were collected from 96 patients with acute type A aortic dissection admitted to our hospital from January 2020 to December 2022. The cohort comprised 61 males and 35 females, with an average age of 52 ± 9.57 years and a mean body weight of 79.54 ± 12.57 kg. The mean diameter of the LSA opening was 11.24 ± 1.48 mm, as measured by computer tomography angiography (CTA) of the thoracoabdominal aorta. All patients underwent emergency Sun's procedure. The surgical method for the LSA stump was selected based on the anatomical location, depth of the subclavian artery, vessel diameter, length of the free vessel, and extent of dissection. Techniques included the use of two Hem-o-lok clips, 5–0 prolene suture with one Hem-o-lok clip, and 5–0 prolene suture alone.ResultsAll the patients successfully completed Sun's procedure as planned. Two Hem-o-lok clips were used to close the stump of the LSA in 38 cases. A combination of 5–0 prolene suture and one Hem-o-lok clip were used to close the stump of the LSA in 54 cases. The LSA stumps for 4 cases were closed with 5–0 prolene suture only. Postoperative complications included cerebral infarction in one patient, renal insufficiency in one patient, and gastrointestinal bleeding in one patient. There were no surgery-related deaths, no paraplegia,and all patients were successfully discharged. The 1-year follow-up CTA of the thoracoabdominal aorta demonstrated effective thrombosis of the false lumen in the stented segment of the thoracic aorta, no aneurysmal dilatation, and successful closure of the LSA stump.ConclusionsThe simplified approach of Hem-o-lok closure of the LSA stump largely mitigates the difficulty in the LSA operation process,shortens the time of operation and reduces bleeding risk, thus effectively improving a patient's prognosis and yielding satisfactory clinical outcomes.

ObjectivesWe aimed to quantitatively analyze wall shear stress (WSS) of the common carotid artery (CCA) and elucidate the relationship between WSS and cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (T2DM) using ultrasound vector flow (V-Flow) imaging.MethodsA total of 109 T2DM patients were selected as the DM group, while 49 healthy volunteers served as the control group. V-Flow examination of the bilateral CCA was conducted. The maximum wall shear stress (WSSmax) and mean wall shear stress (WSSmean) at the bifurcation, proximal bifurcation and middle segment of the bilateral CCA were obtained.ResultsThe DM group showed decreased WSSmean in the middle region and proximal bifurcation of the CCA compared with the control group (p &lt; 0.05). The WSSmean was further decreased in T2DM patients with CVD compared to those without CVD (middle region: 0.71 ± 0.17 Pa vs. 0.84 ± 0.24 Pa, p &lt; 0.05; proximal bifurcation: 0.62 ± 0.22 Pa vs. 0.80 ± 0.21 Pa, p &lt; 0.05). The receiver operating characteristic curve showed that a model combining with age, body mass index and WSSmean at the proximal carotid bifurcation had diagnostic value for detecting CVD in T2DM patients (area under the curve: 0.862, p &lt; 0.05).ConclusionWSSmean has potential value for evaluation of atherosclerosis, as well as in detecting the occurrence of CVD in T2DM patients. Ultrasound V-Flow imaging may be an effective tool for non-invasive evaluation of WSS in the clinic.

IntroductionThe high prevalence of schizophrenia worldwide makes it necessary to proceed from subjective assessment of patient’s clinical symptoms in diagnosis making to searching for circulating blood biomarkers. On the one hand, searching for molecular markers and targets for therapeutics will make it possible to refine and detail the molecular mechanisms of pathology development, while on the other hand, it will offer new opportunities for elaborating novel approaches to disease diagnosis and enhance efficacy and timeliness of drug therapy.MethodsIn this study, we performed an extended-range proteomic analysis of plasma samples collected from 48 study subjects with confirmed diagnosis of schizophrenia and 50 healthy volunteers. The high-resolution tandem mass spectra recorded in the data-dependent acquisition mode were analyzed using the MaxQuant algorithm for the library of known protein sequences and the PowerNovo algorithm for de novo protein sequencing.ResultsIt was demonstrated that both strategies show similar results for high-abundance proteins (≥1 μg/mL). For mid-abundance (10 ng/mL – 1 μg/mL) and low-abundance (&lt;10 ng/mL) proteins, the results obtained by the two search strategies complement each other.DiscussionGroup-specific proteins for the samples of schizophrenia patients were identified, presumably being involved in synaptic plasticity, angiogenesis, transcriptional regulation, protein stabilization and degradation.

BackgroundSystematic study on the relationship between vaginal microbiota and high-risk human papillomavirus infection (HR-HPV) is limited. Hence, the aim of this study is to investigate the correlation between vaginal microbiota and HR-HPV infection through a meta-analysis of case-control studies.MethodsChinese Journal Full-text database, Wanfang database, PubMed database, VIP Chinese Science and Technology Journal database, Web of Science, ScienceDirect, ProQuest, JSTOR, Wiley, and IEEE Xplore were synthetically searched for studies about the correlation between vaginal microbiota and HR-HPV infection. Revman 5.3 software was used to assess the relationship between vaginal microbiota and HPV infection through meta-analysis. Finally, forest map was used to calculate the results and funnel plot was applied to test the publication bias.ResultsFourteen independent studies were admitted in this study, containing a total of 21, 446 women in gynecological outpatients. Compared with HR-HPV negative group, the prevalence of bacterial vaginosis (BV) [odds ratio (OR)=2.45, 95% confidence intervals (CI): 1.83-3.27, P&lt;0.00001], Ureaplasma urealyticum (UU) (OR=1.38, 95% CI: 1.23-1.54, P&lt;0.00001), and Chlamydia trachomatis (CT) (OR=3.53, 95% CI: 2.82-4.41, P&lt;0.00001) increased in HR-HPV positive group through meta-analysis, while, there was no significant difference in the prevalence of trichomonal vaginitis (TV) (OR=1.69, 95% CI: 0.97-2.96, P=0.06) and vulvovaginal candidiasis (VVC) (OR=0.91, 95% CI: 0.54-1.51, P=0.71.ConclusionsVaginal pathogens are closely related to HR-HPV infection. When BV, UU, and CT are abnormal, the risk of HR-HPV infection is increased.

ObjectiveThere is currently no consensus on whether the combination therapy of Vitamin D (VitD) and bisphosphonates offers superior efficacy compared to monotherapy in the treatment of postmenopausal osteoporosis. The aim of this study is to conduct a meta-analysis of recent relevant research to synthesize the available evidence and further investigate whether the combined use of VitD and bisphosphonates is superior to monotherapy in treating osteoporosis in postmenopausal women.Methods and resultsWe systematically searched PubMed, EMBASE, the Cochrane Library, and Web of Science for randomized controlled trials (RCTs) comparing the effects of monotherapy with VitD or bisphosphonates versus their combination therapy in the treatment of postmenopausal osteoporosis, up to 1 February 2024. The articles were independently screened and relevant data were extracted by two investigators. The changes in mean values and percentage changes for bone resorption markers, bone formation markers, bone mineral density, and bone mineral metabolism markers were expressed using the standardized mean difference (SMD) and 95% confidence intervals (CI). Heterogeneity was quantitatively described using the I2 test. Subsequently, sensitivity analyses were performed for data with significant heterogeneity. Subgroup analyses were conducted based on the type of monotherapy used, and potential publication bias was assessed. The analysis revealed that the combination of VitD and bisphosphonates demonstrated a more pronounced effect in increasing alkaline phosphatase (ALP), 25-hydroxyvitamin D (25-OH-VD), and serum calcium (sCa) levels, as well as in decreasing levels of serum bone-specific alkaline phosphatase (sBALP), serum C-terminal telopeptide of type I collagen (sCTX), and urinary N-telopeptide of type I collagen (UriNTX) compared to the monotherapy group. However, the combination of VitD and bisphosphonates did not show a significant advantage over monotherapy in terms of improving osteocalcin levels. The differences in the mean changes in osteocalcin, UriNTX, and sCa, as well as the percentage changes in parathyroid hormone (PTH) were not statistically significant (p &gt; 0.05).ConclusionThe meta-analysis suggests that compared to monotherapy, the combination therapy of VitD and bisphosphonates exhibits a more favorable effect on bone mineral density and bone calcium metabolism-related markers in the treatment of postmenopausal osteoporosis.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/PROSPERO
