This novel approach not only improved MXene stability by arresting oxidation but also increased the available functional groups for further functionalization with various biomolecules. The DSTC NSs were then sequentially conjugated with enzyme glucose oxidase (GOx) and photosensitizer Ce6 to render the obtained CGDSTC NSs with glucose starvation and photodynamic therapeutic properties and thus attain high efficiency in killing cancer cells through the cooperative effect. The as-synthesized CGDSTC NSs demonstrated tremendous photothermal effect with conversion efficiency of 45.1% and photodynamic (ROS generation) properties upon irradiation with 808 and 671 nm lasers. Furthermore, it was observed that the enzymatic activity of CGDSTC NSs increased upon laser irradiation due to enhanced solution temperature. During in vitro studies, the CGDSTC NSs exhibited cytocompatability to HePG2 and HeLa cells under nonstimulus conditions. However, they elicited more than 90% cell-killing efficiency in the presence of glucose and laser irradiation via the cooperative effect between starvation therapy and phototherapy. These results indicate that CGDSTC NSs could be used as potential therapeutic agents to eradicate cancers with no or few adverse effects. This surface modification approach is also simple and facile to adopt in MXene-based research.

However, the education sector experienced better growth compared to national growth. Seeing this, the potential of this sector in West Sumatra needs to be analyzed so that it can be seen whether this sector can be chosen as a priority sector in spurring West Sumatra's economic growth to enter the new normal period. The analysis in this study uses secondary data with the classic Shift Share method. The data in this study are Indonesia's Gross Domestic Product according to Constant Prices and the Gross Regional Domestic Product of West Sumatra according to Constant Prices with the 2019 and 2020 data periods. From the analysis results, it is known that the education sector is growing progressively. This sector in West Sumatra is growing faster than the national one and its competitiveness is better than other sectors in West Sumatra. Another thing according to this research is ...

Perikanan Laut kita ditopang dengan luasnya laut dan perikanan budidaya dengan banyaknya jenis budidaya yang bisa dilakukan. Namun perkembangan perikanan tidak begitu tinggi karena hanya berkontribusi 2,65 % dari PDB Indonesia. Padahal Nilai Tukar Petani Subsektor Perikanan/Budidaya Ikan nilainya sekitar 106,94 yang jauh diatas Nilai Tukar Petani secara umum yaitu berkisar 103,21. Namun nilai yang besar itu tidak dinikmati secara merata pada Provinsi yang ada di Indonesia. Karena adanya perbedaan tersebut maka perlu dilihat kontribusi dan pertumbuhan subsektor ini untuk masing-masing provinsi dengan metode Location Quotient (LQ). Dari hasil analisis diketahui bahwa ada 6 (enam) provisi dengan status unggulan, 11 provinsi pada sektor tertinggal, 16 provinsi pada sektor potensial dan 1 (satu) provinsi pada sektor berkembang

Perekonomian Sumatera Barat juga mengalami masalah akibat Covid-19. Namun sektor pertanian tetap mengalami pertumbuhan di Sumatera Barat. Hal ini dikarenakan kebutuhan manusia dasar dipenuhi pada sektor ini. Sumatera Barat merupakan provinsi yang bergantung pada sektor pertanian karena sepertiga penduduk yang bekerja di Sumatera Barat bekerja pada sektor ini sehingga perlu melihat kesejahteraan Petani di Sumatera Barat pada masa pandemi Covid-19 ini. Salah satu cara melihat kesejahteraan petani ini dengan menganalisis secara deskriptif dengan indikator proxy (pendekatan) yaitu Nilai Tukar Petani (NTP). Nilai NTP secara umum di Sumatera Barat nilainya di atas 100 sehingga bisa disimpulkan kesejahteraan petani terjamin di masa pandemi ini. Namun jika melihat per subsektor pada NTP maka bisa disimpulkan hanya subsektor Perkebunan Rakyat dan Peternakan yang diatas 100. Sedangkan subsektor perikanan, tanaman pangan dan perikanan...

This research is survey and use questionnaire as data collecting tool. This research is a descriptive research analysis, which has the purpose of describing the characteristics of the quality of library services. Sample in this study were 121 respondents. Data analysis techniques used in this study include descriptive analysis, univariate analysis, and multivariate analysis. The results showed: (1) Dimension of service quality that is tangible most significantly and positively influence on visitor satisfaction; (2) service quality dimension that is reliability, assurance and empathy have a significant effect and positively influence on visitor's satisfaction; (3) Dimension of service quality that is responsiveness has a negative and significant effect.

One of the sectors in the GRDP that is one part of the tourism industry is West Sumatra is one of the provinces that have potential in the field of tourism. And If you look at the West Sumatra Province's GRDP, the growth rate of the accommodation and food and beverage sector is the second highest growth rate in the West Sumatra Province's GRDP of 8.11%. The development of tourism through this sector in West Sumatra is inseparable from the contribution of each Regency / Municipality. Therefore, see the importance of the position of this sector in each Regency / Municipality with the Location Quotient (LQ) Approach. Regency / Municipality in West Sumatra consist of one Municipality which is a leading sector, Six Municipality which are potential sectors, Four Regencies which are developing se...
