Abstract

Pengukuran volume zat cair yang sensitif dapat dicapai menggunakan alat ukur atau sensor. Akan tetapi sensor volume zat cair tidak banyak mengembangkan, padahal pengukuran volume berdampak langsuang pada  nilai ekonomis, keberhasilan penelitian ilmiah,  dan kemanjuran dosis obat. Penelitian yang telah dilakukan hanya sebatas pada pengukuran pada kenaikan permukaan zat cair  dalam kenaikan tandon. menggunakan sensor fotodioda. Metamaterial telah banyak dikembangakan sebagai sistem sensor yang sensitif karena berbasis gelombang elektromagnetik, namun belum spesifik mengkajinya sebagai sensor volume zat cair. Tujuan penelitian ini adalah untuk merancang dan menyimulasikan penggunaan sensor metamaterial yang sensitif dalam pengukuran volume zat cair.  Sensor didesain dengan prinsip split ring resonator berbentuk rektangular (SRR-R) yang terdiri  dari cincin logam tembaga dan substrat FR4-Epoxy. Sensor SRR-R disimulasikan pada rentang frekuensi 350-850 MHz untuk mendeteksi perubahan volume zat cair (aquades, air tawar dan etanol) dari 5 - 44 ml. Hasil simulasi menunjukan terjadinya pergeseran frekuensi resonan spektrum S21 yang  jelas untuk masing-masing zat cair. Pergeseraan frekuensi resonan untuk sampel aquades terjadi pada frekuensi 403 – 527 MHz, air tawar 403 – 528 MHz, dan etanol 60 – 783 MHz. Distribusi medan E dan medan H menunjukan nilai maksimum sebesar 18662 V.  dan 43771 A. . Karakteristik kurva linier terjadi dalam rentang volume 12-44 ml untuk semua sampel zat cair. Sensor metamaterial SRR-R berhasil disimulasikan untuk mendeteksi perubahan volume zat cair dengan sensitivitas pengukuran aquades -1.3999 MHz/ml, air tawar -2.6833 MHz/ml, adan etanol -3.5685 MHz/ml.

Abstract

The diagnosis of childhood tuberculosis remains a challenge worldwide. The GeneXpert MTB/RIF test, a rapid Mycobacteria tuberculosis diagnostic tool, was recommended for use in children. No pediatric studies of GeneXpert MTB/RIF assessing pulmonary tuberculosis within a hospital setting has been done in Indonesia. We evaluated the performance of the GeneXpert MTB/RIF test compared with sputum culture on Lowenstein-Jensen (LJ) for the diagnosis of childhood pulmonary tuberculosis. This study was conducted in pediatric respirology inpatient and outpatient Dr. Soetomo Hospital, a tertiary care facility in Surabaya between June and August 2015 with a cross-sectional design. We consecutively enrolled 27 children aged 3 months to 14 years who had history of close contact with adult tuberculosis patients and showed symptoms of pulmonary tuberculosis. Sputum collection was performed by induced sputum and three examination methods were performed (microscopic, GeneXpert MTB/RIF and sputum culture) simultaneously followed by a drug sensitivity test for specimens detected with MTB growth. The GeneXpert MTB/RIF test had a sensitivity of 100% (95% CI 100-100) and a specificity of 95% (95% CI 85-100). The positive predictive value for diagnosing pulmonary TB was 89% (95% CI 68-100), the negative predictive value was 100% (95% CI 100-100) and positive likelihood ratio was 20 (95% CI 2.82-128). The GeneXpert MTB/RIF test on one sputum sample rapidly and correctly identified all children with culture-confirmed pulmonary tuberculosis with high specificity. Similar results were obtained between GeneXpert MTB/RIF and sputum culture based on age groups and clinical manifestations. Rifampicin resistance were both detected in GeneXpert MTB/RIF and MTB sensitivity test

Abstract

During adolescence, students begin to develop purpose in life and strategies to achieve them. The perceived social support of teachers is an initial stimulus for students to discover life goals. However, gratitude can also be a positive predictor for students to reflect on support, experiences, and challenges to find purpose in life that have an impact on the environment. The present study focused on examining the effect of perceived teachers' social support on purpose in life with gratitude as the mediator variable. This study used quantitative methods with a mediation design. The participants in this study were 204 SMA/MA/SMK students in grades 10-12, aged 15-18 years, and domiciled in Indonesia. Data collection used accidental sampling and snowball sampling where questionnaires were distributed online through social media. Data analysis was conducted using JASP 0.14.1 and hypothesis testing through mediation analysis with a causal steps model. The results of the mediation analysis showed that perceived teachers' social support has a significant influence on purpose in life through gratitude as a mediator variable, but the resulting mediation effect is partial. The implications of this research can help the school environment, especially teachers, in helping students find a meaningful purpose in life.Pada usia remaja, pelajar mulai merancang purpose in life dan strategi untuk mencapainya. Adanya perceived teacher’s social support menjadi stimulus awal bagi pelajar untuk menemukan purpose in life. Akan tetapi gratitude juga dapat menjadi prediktor positif bagi pelajar untuk merefleksikan dukungan, pengalaman, dan tantangan untuk menemukan purpose in life yang berdampak bagi lingkungan. Melalui penelitian ini, peneliti berfokus untuk menguji pengaruh perceived teacher’s social support terhadap purpose in life dengan gratitude sebagai variabel mediator. Penelitian ini menggunakan metode kuantitatif dengan desain mediasi. Partisipan dalam penelitian ini adalah pelajar SMA/MA/SMK kelas 10-12, berusia 15-18 tahun, dan berdomisili di Indonesia. Pengambilan data menggunakan accidental sampling dimana kuesioner disebarkan secara online melalui media sosial. Analisis data dilakukan menggunakan JASP 0.14.1 dan uji hipotesis melalui analisis mediasi dengan model causal steps. Hasil analisis mediasi menunjukkan perceived teacher’s social support memiliki pengaruh yang signifikan terhadap purpose in life melalui gratitude sebagai variabel mediator, tetapi efek mediasi yang dihasilkan bersifat parsial. Implikasi hasil penelitian ini dapat membantu lingkungan sekolah terutama guru dalam mendampingi siswa menemukan purpose in life yang bermakna.

Abstract

Utilizing palm frond biomass for the production of composite materials will have a positive impact on managing palm oil plantation waste. Palm frond fiber biocomposite products have been proven to have good mechanical properties. However, exploration of other physical properties, especially thermal insulation properties, has not been widely studied. As a non-conducting material, palm frond fiber has the potential to have good thermal insulation properties. This study aims to fabricate palm frond biocomposite fiberboard, which has potential as a thermal biocomposite material. Fiberboard is made using the manual hand lay-up technique and cold compaction using a press machine. The characteristics under consideration for the fiberboard in concern encompass its physical, mechanical, and thermal properties. The main ingredients utilized in the fabrication of fiberboard predominantly comprise palm frond fiber and epoxy resin, with five distinct sample variants denoted as PSP-1 (84% fiber:16% resin), PSP-2 (83% fiber:17% resin), PSP-3 (82% fiber:18% resin), PSP-4 (81% fiber:19% resin), and PSP-5 (80% fiber:20% resin). The experimental results obtained from the testing of physical parameters indicated that the density of fiberboard exhibited a range of values spanning from 0.28 g/cm3 to 0.55 g/cm3. Similarly, the fiberboard's water absorption capacity varied between 107.25% and 194.00%. The water absorption abilities display significant variability, as indicated by a large standard deviation ranging from 28.15% to 80.35%. When the density of fiberboard is high, its water absorption capacity tends to be low. Furthermore, the mechanical tests revealed that the fiberboard's flexural strength showed a range of values spanning 1.10-5.42 MPa. The magnitude of specific heat capacity for fiberboard is calculated to be between 2.1-3.5 J/g ̊C, while the thermal conductivity lies within the range of 0.001-0.0020 W/mK

Abstract

Interest in sharia loans may be significantly lower than regular internet loans. Online Sharia loans are safer than conventional loans as they do not incur interest or usury and do not impose penalties for late payments. This study seeks to ascertain public perceptions regarding the utilization of Sharia-compliant P2P lending as a means to mitigate illicit online loan fraud. The employed methodology is a mixed methods research strategy, specifically quantitative utilizing the TAM model and qualitative through structured interviews, aimed at acquiring deeper insights from relevant sources. This research sample used 167 respondents with the criteria namely people who have knowledge or experience using Sharia P2P Lending. The research findings indicate that trust and comfort affect individuals' views and interest in utilizing P2P syariah lending. Attitudes affect individuals' desire to utilize Sharia P2P Lending, whereas risk perceptions do not influence their attitudes or interests. Moreover, the significance of Sharia P2P Lending is paramount, as it functions by Sharia principles that prioritize justice, transparency, and the avoidance of usury, gharar, and maysir. Digital literacy, particularly in financial matters, is essential to avert illicit online loan fraud.
