Judul: Analisis Faktor-Faktor Yang Memengaruhi Profitabilitas Bank Pembiayaan Rakyat Syariah (BPRS) Di Provinsi Jawa Timur
Abstrak: Bank Pembiayaan Rakyat Syariah (BPRS) merupakan salah satu bentuk perbankan syariah yang lebih berfokus pada pembiayaan pada sektor menengah kebawah. Profitabilitas merupakan indikator dari kinerja BPRS yang digunakan untuk melakukan evaluasi kinerja BPRS. Penelitian ini bertujuan untuk menganalisis faktor-faktor apa saja yang memengaruhi profitabilitas BPRS di Jawa Timur. Data yang digunakan dalam penelitian ini adalah data kuartalan dari tahun 2020 hingga 2022 yang dianalisis dengan metode regresi linier berganda. Hasil analsis data menunjukkan bahwa Kualitas Aktiva Produktif (KAP) dan Non-Performing Financing berpengaruh positif (signifikan) terhadap profitabilitas BPRS, Biaya Operasional terhadap Pendapatan Operasional (BOPO) dan Cash Ratio berpengaruh negatif (signifikan) terhadap profitabilitas BPRS.

Judul: Faktor-Faktor Yang Memengaruhi Tingkat Profitabilitas BPRS di Sumatera Barat
Abstrak: Salah satu indikator kinerja keuangan adalah profitabilitas. Bank Pembiayaan Rakyat Syariah (BPRS) memiliki potensi besar di Sumatera Barat dalam menyalurkan pembiayaan karena memiliki penduduk mayoritas muslim serta jumlah UMKM terbanyak ketiga di Sumatera. Akan tetapi, nilai profitabilitas BPRS di Sumatera Barat berada di bawah standar BI. Penelitian ini bertujuan untuk menganalisis perkembangan kinerja BPRS serta faktor-faktor yang memengaruhi profitabilitas BPRS di Sumatera Barat pada periode 2020 hingga 2022. Sampel penelitian ini terdiri atas 7 BPRS dan dianalisis dengan regresi data panel. Hasil penelitian menunjukkan bahwa secara parsial, variabel cash ratio berpengaruh positif (signifikan) terhadap profitabilitas dan variabel BOPO berpengaruh negatif (signifikan) terhadap profitabilitas. Sementara itu, variabel FDR, NPF, IHK dan PDRB tidak berpengaruh terhadap profitabilitas., One of indicators to measure financial performance is profitability. Islamic Rural Banks has great potential in West Sumatera to provide financing because it has a Muslim majority population and being the third largest MSMEs in Sumatera. BPRS in West Sumatera has profitability below the Bank Indonesia (BI) standard. This study aims to analyze the development of BPRS performance and the factors those affect the profitability of BPRS in West Sumatera during the period 2020 to 2022. The research sample consists of 7 BPRS and used panel data regression to analyze. The result of study shows that partially the cash ratio variable has a positive effect (significant) on profitability and the BOPO variable has a negative (significant) effect on profitability. One the other hand, the variables FDR, NPF, IHK and PDRB have no effect on profitability.

Judul: Growth, Concentration Chlorophyll-a, and Structure of Macroalgae Gracilaria edulis in the Culture Media Containing Copper
Abstrak: The physiological responses (specific growth rate, concentration of chlorophyll-a, morphological and anatomical structure of the vegetative cells) of the marine macroalga Gracilaria edulis at the different concentrations of copper (0.01 as control, 0.04, 0.06 and 0,5 ppm) delivered continuously for 28 days under controlled laboratory conditions were investigated. Result showed that the degree of copper toxicity depends on both factor the concentration and exposure time. Copper concentration and day of exposure decreased significantly the specific growth rate (SGR) of the Gracilaria edulis but only 0,5 ppm Cu decreased the chlorophyll-a content when compared to control. Of the various physiological end points measured, growth proved to be the most sensitive response than chlorophyll-a with reductions in specific growth rate (SGR). The reason for this could be related to a greater sensitivity of the enzymes involved in growth than those related to chlorophyll-a or a greater energy needs to maintain cellular integrity and metabolic processes under sublethal Cu stress. In all cases, the main effect on vegetative cells were structure changes in cortex and subcortex cells, compared to control, macroalgae exposed to copper showed depigmentation and blending in the lateral branches, heavy staining of the cell wall and severe damage of cell membrane, while the mucilage and the cell walls was densely fibrillar, thick and heavily stained, the cortex cell was clearly vacuolated, the presence of endophytic on the cell wall and endophytic spores in the mucilage. The presence vacuoles should be related to a metal immobilization mechanism, minimizing the Cu toxicity for cells. The epiphytic bacteria can act as a biofilter diminishing the availability of Cu for macroalgae accumulation.
