Abstract

nterpretasi anomali self-potential (SP) model geometri sederhana (fixed geometry) sederhana, dilakukan untuk menghitung kedalaman, sudut polarisasi benda, moment dipole listrik, dan bentuk struktur benda dibawah permukaan yang mempengaruhi data SP yang diamati diatas permukaan. Dalam mengidentifikasi parameter anomali SP akibat dari model fixed geometry dibawah permukaan bumi dapat dilakukan dengan cara pemodelan inversi. Dalam tulisan ini pemodelan inversi diselesaikan menggunakan pendekatan linier dengan metode least-square terbobot dan metode Levenberg-Marquardt. Kedua metode ini diaplikasikan untuk menentukan nilai parameter dari anomali self-potential akibat struktur sesar, dengan menganggap struktur sesar menyerupai bentuk lempeng. Metode least-square terbobot dan Levenberg-Marquardt mampu mengikuti pola hasil data pengukuran di lapangan. Kedua metode inversi tersebut efisien karena proses perhitungannya yang relatif singkat serta nilai parameter model struktur lempeng hasil perhitungan kedua metode tersebut menunjukkan hasil yang sama hanya terdapat sedikit selisih perhitungan pada nilai kemiringan sudut lempeng.Kata kunci: anomali self-potential, fixed geometry, pendekatan linier

Abstract

Desa Wiringtasi di Kecamatan Suppa Kabupaten Pinrang merupakan salah satu desa yang menjadi prioritas kegiatan pengabdian kepada masyarakat pada tahun 2019. Desa ini mempunyai potensi kekayaan rumput, namun belum dapat dimaksimalkan pengolahannya. Kegiatan ini bertujuan untuk meningkatkan keterampilan warga dalam mengolah rumput laut menjadi sajian penuh gizi. Tanggapan para peserta kegiatan ini juga sangat bagus. Para warga juga sebelumnya belum dapat pelatihan seperti ini, sehingga mereka sangat aktif dalam keikutsertaannya.

Abstract

The synthesis of MgxN1-xFe2O4/SiO2 composite nanoparticles, where x=0; 0.25; 0.5; 0.75; 1.0 through coprecipitation method and low temperatures had been successfully carried out. The result of X-ray Diffractometer (XRD) informed that the sample had crystalline forms and different crystallite sizes as the Mg concentration in the sample is increased. The sizes of crystallite produced were between 12.12 to 24.47 nm. In addition, theoretically and experimentally there were differences grid parameters with the energy bandgap of the nanocomposite sample ranged from 2.51 to 2.66 electron volt (eV). Therefore, the MgxN1-xFe2O4/SiO2composite nanoparticles could be referred to the nano-photocatalyst or nano-adsorbent for organic pollutant due to its potential to degrade Methylene Blue waste.

Abstract

Hand sanitizer products on the market generally contain alcohol which can cause dry hands and dehydration of the skin, therefore alternative ingredients that are skin-friendly and do not irritate the skin are needed such as the use of natural ingredients. One of them is bay leaf (Syzygium polyanthum). Salam plant is a plant that has antibacterial properties. The main ingredients that have antibacterial properties are flavonoids, tannins, essential oils, steroids, so that bay leaves can be used as a hand sanitizer to reduce alcohol use. The manufacture of bay leaf hand sanitizer is done by extracting the bay leaves with 96% ethanol solvent. The extraction results are then dissolved with other supporting materials which are certainly safe for health. It is hoped that the bay leaf hand sanitizer will be a safer alternative to hand sanitizers than alcohol-based hand sanitizers

Abstract

The Self-Potential (SP) method was used to identify changes in the potential groundwater in the area of Gampong Lengkong, Langsa City. The data acquisition technique was carried out with a fixed base technique with a measurement count of four acquisition lines. Research is conducted for two months that July and August are the same to monitor the changes in the SP value associated with the change of SP anomaly. SP value of the acquisition result is used as a reference for estimating the potential of groundwater. Interpretation is made qualitatively and quantitatively. Qualitative interpretation through analysis maps of the isopotential contours compared between the first month and the second month of measurements in the field. The interpretation is quantitatively by assuming the source of the subsurface anomaly fix geometry models of cylinders or spheres is done by the inversion modeling using the Levenberg-Marquardt method. The results showed that there was a reduction in SP value in the second month, indicating the potential shortage of groundwater in the region. The decrease in groundwater potential is also shown in the inversion results, where the result of the calculation of SP anomaly source parameters in the first month is estimated to be at 7.77 meters to 11.05 meters below the ground in the monthly measurements second.

Abstract

Dental caries is a problematic area in pediatric dentistry, with Streptococcus mutans as the dominant bacterial cause. Green tea solution and chlorhexidine were effective in reducing the number of Streptococcus mutans. But study about the differences of these two materials has not been done. Objective: The aim of this study was to determine differences in the effectiveness of rinsing with 0.2% chlorhexidine and 2.5% green tea solution in reducing the number of Streptococcus mutans. Methods: This study is quase experimental study with cross-over design. Thirty children aged 6-12 years with poor OHI-S index were participated. Samples of saliva were taken respectively before rinsing for 3 seconds with 0.2% chlorhexidine solution and a solution of 2.5% green tea and 15 minutes followed 30 minutes after rinsing intervention. Saliva samples were taken to the laboratory then the number of Streptococcus mutans count were evaluated. The statistical analysis were performed by SPSS version 18.0 with ANOVA, t-paired and LSD test. Results: ANOVA test result showed that the decrease generated by each mouthwash is a significant reduction. T-paired test result showed that there is no difference in the number of Streptococcus mutans colonies significantly between chlorhexidine and green tea solution at 15 minutes dan 30 minutes after rinsing. Conclusion: There is no significant difference between chlorhexidine and green tea solution in reducing the number of Streptococcus mutans.

Abstract

Perilaku altruistik merupakan tindakan sukarela yang dilakukan oleh individu demi menolong orang lain tanpa mengharapkan imbalan. Penelitian ini bertujuan untuk mengukur tingkatan perilaku altruistik guru (Guru Mata Pelajaran dan Guru Pembimbing) dalam mendidik anak berkebutuhan khusus di sekolah dasar Inklusi Kota Banda Aceh, serta perbedaan perilaku altruistik dari kedua kelompok guru tersebut. Penelitian ini menggunakan pendekatan kuantitatif dengan metode komparatif. Subjek penelitian adalah 34 orang guru mata pelajaran dan 34 orang guru pembimbing. Pengumpulan data menggunakan skala altruistik dan dianalisis menggunakan analisis deskriptif persentase dan uji-t. Hasil penelitian menunjukkan 88,2% guru mata pelajaran di SDN Inklusi Kota Banda mempunyai perilaku altruistik kategori tinggi dengan nilai mean = 142,15, sedangkan 44,1% guru pembimbing di SDN Inklusi Kota Banda Aceh mempunyai perilaku altruistik yang sangat tinggi dengan nilai mean = 150,9. Hasil uji-t menunjukkan nilai t hitung 3,506 (t tabel 1,996 sig. 0.001). Artinya, terdapat perbedaan yang signifikan antara perilaku altruistik guru mata pelajaran dan guru pembimbing dalam mendidik anak berkebutuhan khusus di Sekolah Dasar Inklusi Kota Banda Aceh. Peneliti selanjutnya disarankan untuk melibatkan variabel lain dan pendekatan penelitian yang berbeda, seperti kecedasan emosi, simpati dan juga dapat memperdalam penelitian ini dengan observasi dan wawancara sehingga dapat diperoleh hasil yang lebih mendalam.

Abstract

This study aims to obtain an overview of the leadership intelligence of Guidance and Counseling students based on their ethnic backgrounds in the province of Aceh, namely Aceh, Gayo, and Kluet tribes. This research employed a quantitative research approach. Data was collected through the Leadership Intelligence Questionnaire (LIQ) instrument developed by Ronthy. The research population was all students in Guidance and Counseling in the even semester of 2020/2021, totaling 343 students. By using the Slovin formula, the research sample amounted to 185 people. The research data used descriptive analysis. Thus, it can provide an overview of the leadership intelligence profile of student groups in each ethnic group which can be the basis for developing personal services and as a reference in research development related to socio-cultural-based guidance and counseling.
