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: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
