Judul: Efisiensi Kantor Cabang di BPJS Ketenagakerjaan Tahun 2018-2020
Abstrak: BPJS Ketenagakerjaan menghadapi tantangan untuk memperluas cakupan kepesertaan dan menjamin keuangan yang berkelanjutan. Jumlah peserta relatif rendah, dan hal ini juga diperparah dengan Covid-19 karena meningkatkan jumlah pengangguran dan pembayaran klaim. Dengan memaksimalkan sumber daya, BPJS Ketenagakerjaan masih memiliki potensi yang besar untuk mendorong produktivitas dan meningkatkan efisiensi. Penelitian ini bertujuan untuk menganalisa efisiensi dari kantor cabang BPJS Ketenagakerjaan. Data Envelopment Analysis (DEA) digunakan untuk mengestimasi efisiensi pada 26 kantor cabang pada periode 2018-2020. Hasil menunjukkan bahwa rata-rata kantor cabang efisien. Selanjutnya, regresi model Tobit digunakan untuk menginvestigasi faktor yang mempengaruhi efisiensi. Penemuan baru menunjukkan hasil yang positif signifikan pada pergantian kepala kantor cabang, lokasi operasional, dan proporsi penduduk yang bekerja namun, Covid-19 memiliki hasil yang negatif signifikan terhadap efisiensi. Sementara itu, tipe kantor cabang dan pertumbuhan Bruto Regional Domestik Bruto (PDRB) menunjukkan hasil yang tidak signifikan. Rekomendasi dari penelitian ini yaitu BPJS Ketenagakerjaan dapat meningkatkan efisiensi dengan memotivasi kepala cabang dengan melakukan rotasi, meningkatkan kinerja kantor cabang di Pulau Jawa dan memperkuat kerjasama dengan pemerintah dan penegak hukum, ocial security agency for employment in Indonesia that called BPJS Ketenagakerjaan faces challenges in extending membership coverage and ensuring sustainable financing. The number of participants is relatively low and Covid-19 also exacerbates by increasing unemployment and claim payment. By maximizing the resources, this institution still has a huge potential to advance productivity and elevate levels of efficiency. This paper is aimed to analyze the efficiency of BPJS Ketenagakerjaan’s branch offices. Data Envelopment Analysis (DEA) was used to estimate the efficiency score among 26 branch offices over the period of 2018-2020. Results show that on average, the branch offices were efficient. Furthermore, the Tobit Regression Model is used to investigate the determinants of efficiency. New findings indicate that significant positive effects among switching of branch managers, operational location, and proportion of working population, yet, Covid-19 has a significant negative effect on efficiency. Meanwhile, the type of branch offices and the growth of Gross Domestic Regional Bruto (GDRP) show insignificant results. This study suggests that BPJS Ketenagakerjaan could be efficient by motivating the branch manager, enhancing the performance of branch office in Java Island and the collaborating with government and law enforcement.

Judul: Analisis Efisiensi BPRS di Wilayah Jabodetabek Periode Sebelum dan Selama Pandemi COVID-19
Abstrak: Kinerja Bank Pembiayan Rakyat Syariah (BPRS) di Indonesia mengalami perkembangan yang fluktuatif, termasuk BPRS yang berada di wilayah Jakarta, Bogor, Depok, Tangerang dan Bekasi (Jabodetabek). Terjadinya perubahan kinerja BPRS serta pandemi COVID-19 masuk di Indonesia menyebabkan perlu adanya pengukuran kinerja BPRS. Penelitian ini bertujuan untuk menganalisis tingkat efisiensi BPRS di Jabodetabek dan membandingkan rata-rata nilai efisiensi BPRS sebelum dan selama pandemi COVID-19. Sampel yang digunakan adalah 11 BPRS di Jabodetabek. Metode analisis yang digunakan adalah analisis deskriptif dan analisis kuantitatif. Metode kuantitatif yang digunakan pada penelitian ini adalah Data Envelopment Analysis (DEA). Besarnya nilai standar deviasi dari output yang digunakan menunjukkan bahwa tedapat perbedaan yang cukup besar dalam jumlah output yang dihasilkan BPRS. Hasil penelitian dengan DEA terdapat 10 Decision Making Unit (DMU) memiliki skor efisiensi sebesar 100 persen sebelum pandemi dan 9 DMU selama pandemi. Pada uji Mann-Whitney menunjukkan bahwa tidak terdapat perbedaan rata-rata nilai efisiensi sebelum dan selama pademi COVID-19. Kata, The performance of Islamic Rural Banks (BPRS) in Indonesia has fluctuated, including BPRS in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek).The purpose of this study is to assess BPRS efficiency in Jabodetabek and compare BPRS efficiency before and during the COVID-19 pandemic. In Jabodetabek, 11 BPRS were used as a sample. The analytical methods used are descriptive analysis and quantitative analysis. Data Envelopment Analysis was the quantitative method used in this study (DEA). The magnitude of the standard deviation of the output used indicates that there is a significant difference in the amount of output produced by the BPRS. According to the findings of the DEA study, 10 Decision Making Units (DMU) had an efficiency score of 100 percent before the pandemic and 9 DMU during the pandemic. According to the Mann-Whitney test, there is no difference in the average efficiency value before and after the COVID-19 pandemic.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
