Abstract

Pada triwulan 1 2016 beberapa bank seperti bank mandiri mengalami penurunan profit diikuti oleh bank BTPN, bank Artha graha dan lain. Penurunan profit bank ini disebabkan oleh bankbank tersebut beroperasi tidak efisien. Pada beberapa semester belakangan ini peneliti telah melakukan penelitian tentang faktor-faktor yang mempengaruhi profitabilitas perbankan diman peneliti telah melakukan penelitian di bank swasta,BPR,dan BUMN dimana hasil dari penelitian tersebut menunukkan bahwa penurunan tingkat profitabilitas itu disebabkan oleh bank-bank tersebut tidak efisien dimana nilai efisiensinya diukur dengan rasio efisiensi keuangan yaitu BOPO.Berdasarkan fenomena yang dijelaskan diatas maka peneliti tertarik untuk melakukan penelitian dengan judul Faktor-Faktor yang empengaruhi Efisiensi Perbankan suatu Studi pada Bank BUMN yang Terdaftar di Bursa Efek Indonesia.Adapun peumusan masalah penelitian ini adalah seberapa besar modal berpengaruh terhadap efisiensi bank,seberapa besar likuiditas berpengaruh terhadap efisiensi bank, seberapa besar Net interest Margin berpengaruh terhadap efisiensi bank seberapa besar pengaruh resiko terhadap efisiensi bank dan Seberapa besar kepemilikan berpengruh terhadap efisiensi bank.Tujuan penelitian ini adalah untuk menguji pengaruh modal terhadap efisiensi bank ,untuk menguji pengaruh likuiditas terhadap efisiensi bank, untuk menguji pengaruh Net interest margin terhadap efisiensi bank, untuk menguji pengaruh resiko terhadap efisiensi bank dan untuk menguji pengaruh kepemilikan terhadap efisiensi bank.Hasil penelitiannya adalah bahwa ada 3 variabel yang mempengaruhi efisiensi bank pemerintah yaitu NPL,ROA dan LDR. Pengaruh variabel ROA bersifat negatif sedangkan pengaruh LDR dan NPL terhadap efisiensi bank pemerintah bersifat positif. Pengujian simultan menunjukkan hasil bahwa CAR,NPL,LDR,ROA,NIM,total aset dan tingkat bunga pasar secara bersama-sama mempengaruhi efisiensi bank pemerintah. Dimana pengaruh ke tujuh variabel ini hanya 89,8% saja.

Abstract

Pendahuluan: Plak merupakan deposit lunak yang melekat erat pada permukaan gigi. Salah satu usaha untuk mengontrol pembentukan plak adalah tindakan secara mekanis yaitu menyikat gigi. Ada beberapa teknik menyikat gigi yang dianjurkan anak-anak. Setiap teknik mempunyai kelebihan dan kekurangan. Supaya gigi dan mulut dapat dibersihkan dengan maksimal dapat dilakukan teknik kombinasi yang mempunyai efek saling melengkapi. Tujuan: mengetahui perbedaan perbedaan hygiene index murid yang menyikat gigi dengan teknik kombinasi vertikal horizontal dan Fone’s horizontal di SDN 11 Aur Kuning Kota Bukittinggi. Metode: pre-experiment dengan rancangan “pretest and postest”. Teknik pengambilan sampel adalah sensus sebanyak 46 orang. Pengumpulan data melalui observasi dan perlakuan, kemudian dianalisis menggunakan uji T-Test. Temuan penelitian menunjukkan tidak terdapat perbedaan yang signifikan antara hygiene index murid yang menyikat gigi dengan teknik kombinasi vertikal horizontal dan Fone’s horizontal dengan p-value = 0,110 dengan rata-rata selisih peningkatan hygiene index sebesar 40,26% sebelum dan sesudah menyikat gigi dengan teknik kombinasi vertikal horizontal dan 33,24% pada teknik kombinasi Fone’s horizontal. Kesimpulan: kedua teknik ini sama-sama dapat meningkatkan hygiene index. Teknik kombinasi vertikal horizontal lebih efektif dalam meningkatkan hygiene index. Disarankan kepada murid sekolah dasar untuk menyikat gigi sesuai dengan teknik kombinasi yang sudah diajarkan

Abstract

This study aims to determine the effect of gross profit, operating profit, net income, changes in receivables, changes in payables and changes in inventory in predicting future cash flows (empirical studies on mining companies listed on the Indonesia Stock Exchange in 2016-2020). The population in this study are all mining companies listed on the Indonesia Stock Exchange (IDX) in 2016-2020. The total population in this study were 47 mining companies.The sampling technique used purposive sampling method which resulted in 12 companies as samples. The results showed that gross profit, operating profit, net income, changes in debt, and changes in inventory had an effect on predicting future cash flows, while changes in accounts receivable had no effect on predicting future cash flows. Then there is the effect of gross profit, operating profit, net profit, changes in receivables, changes in debt and changes in inventory in predicting future cash flows simultaneously.

Abstract

Dental health education is one of the programs to tackle dental health problems in Indonesia. The selection of the appropriate method in delivering educational material significantly contributes to the achievement of the targeted behavior change. Demonstration is one of the methods commonly used in this process. The demonstration method can be amplified by incorporating audio-visual media. It can be used to deliver the material more interestingly so that learning can be more interactive. This study aims to determine dental health education using demonstrations and videos on toothbrushing behavior changes among primary school students aged 9-12 years old. This research is quasi-experimental with Pretest-Posttest Group Design. The research samples are students aged 9-12 years old at SDS Al-Azhar Bukittinggi with a total number of 100 students. These samples were collected by simple random sampling. The research procedure started by giving a pre-test followed by a demonstration and video presentation about toothbrushing for different groups. The research then ended with a post-test to find out tooth brushing behavior. The data were analyzed using Wilcoxon and Mann-Whitney test. From the results of the Wilcoxon test, dental health education with demonstration method and video before and after the treatment obtained a significance value of 0.000 <0.05. It indicates that dental health education with demonstrationmethod and video effectively improves the respondent's toothbrushing behavior. The Mann-Whitney test showed a significance value of 0.000 < 0.05. It indicates that there is a difference in toothbrushing behavior between the demonstration method and video. Dental health education with the demonstration method is more effective in changing the respondent's toothbrushing behavior. Therefore, it is recommended for school teachers and UKGS officers to conduct dental health education using the demonstration method to change the toothbrushing behavior of elementary school students.

Abstract

A composite is a material formed from a combination of two or more constituent materials using a heterogeneous mixing process, whose mechanical properties vary. The aim of this research is to compare the tensile strength values ​​of abaca banana stem fiber polyester composites with variations in fiber orientation. The fiber orientation used is parallel, random and woven. The method used is a hand lay-up press with a fiber volume fraction of 30% and the resin itself uses BQTN 157 EX polyester resin with a hand lay-up method using a glass mold. The test was carried out by tensile testing using the ASTM D3039 measurement standard and macro photos. The results of research on tensile testing show that composites with variations in parallel fiber orientations reinforced with abaca banana stem fibers have an average tensile strength of 39.63 MPa, variations in random fiber orientation have an average tensile strength of 32.87 MPa and variations in fiber orientation woven has an average tensile strength of 25.90 MPa. From the results of macro photo fracture observations, it was found that the type of fracture is a brittle fracture on an uneven fracture surface which causes fiber pull-out where the fibers appear to be coming out of the specimen because the matrix and fibers are not strongly bonded and the fracture is also caused by voids near the fibers.
