Pengungkapan Sukarela Berdasarkan Karakteristik Perusahaan dan Kepemilikan Institusional
Abstract This study analyses the effect's degree of firm characteristics and institutional ownership on voluntary disclosure. Firm characteristics in this study are measured based on size and leverage. This study's panel data are from financial reports of 23 companies in the consumer goods industry listed on the Indonesia Stock Exchange for the 2014 to 2018 reporting period. By using panel data regression analysis, this study finds that company size does not affect voluntary disclosure. On the other hand, leverage positively affects voluntary disclosure, while institutional ownership has a negative effect. This study implies that voluntary disclosure is more determined by the need to win the competition and rationalize investors regarding their leverage. The company's size does not determine the voluntary disclosure level. The government needs to encourage the companies to reveal more information for better market within the pandemic through the Financial Services Authority. On the other hand, institutional ownership that has a negative effect on voluntary corporate disclosure shows that investors from other institutions tend not to have healthy controls in encouraging companies to make voluntary disclosures. Future research is expected to reexamine corporate voluntary disclosure determinants through other variables and use more than one method to ensure their robustness results. Keywords: Firm Characteristic; Institutional Ownership; Voluntary Disclosure AbstrakPenelitian ini bertujuan untuk menganalisis besarnya pengaruh karakteristik dan kepemilikan institusional terhadap pengungkapan sukarela yang dilakukan perusahaan. Karakteristik perusahaan dalam penelitian ini diukur berdasarkan ukuran dan leverage. Data dalam penelitian ini yakni laporan keuangan dari 23 perusahaan sektor industri barang konsumsi yang terdaftar di Bursa Efek Indonesia periode laporan 2014 hingga 2018. Dengan menggunakan analisis regresi data panel, penelitian ini menemukan bahwa ukuran perusahaan tidak mempengaruhi pengungkapan sukarela. Di sisi lain, leverage berpengaruh positif terhadap pengungkapan sukarela, sedangkan kepemilikan institusional berpengaruh negatif. Implikasi penelitian ini adalah bahwa pengungkapan sukarela lebih ditentukan oleh kebutuhan untuk memenangkan persaingan serta keperluan memberikan rasionalisasi terhadap para investor terkait besarnya leverage yang dimiliki. Besar kecilnya ukuran perusahaan tidak menentukan tingkat pengungkapan sukarela sehingga pemerintah melalui OJK perlu mendorong pengungkapan sukarela perusahaan. Di sisi lain, kepemilikan institusional yang justru berpengaruh negatif terhadap pengungkapan sukarela menunjukan investor dari institusi lain cenderung belum memiliki pengendalian yang kuat dalam mendorong perusahaan agar melakukan pengungkapan sukarela. Penelitian selanjutnya diharapkan dapat menelaah kembali determinan pengungkapan sukarela melalui variabel-variabel lain serta menggunakan lebih dari satu metode untuk memastikan hasil yang robust.

PRODUKSI LIPASE DARI ISOLAT KAPANG HASIL MUTASI UNTUK TRANSESTERIFIKASI
Lipase Production by Mutant Fungal Isolates for Transesterification ABSTRACTLipase is used amongst others in biodiesel production, namely in the transesterification reaction. Kernel B (KB) was a fungus isolated from the waste of palm kernel and seed. The fungus produced lipase that catalysed the transesterification reaction with a lower activity compared to that of AK Amano commercial lipase. The purpose of this study was to obtain mutant fungi with higher transesterification activities than the wild type (KB). The mutation process was carried out using ultraviolet (UV) light, ethyl methane sulfonate (EMS), and N-methyl-N’-nitro-N-nitrosoguanidine (NMNG) on KB fungus. The mutations using UV light produced 11 isolates, of which isolate m4.1KB1 produced a higher transesterification activity (0.172 U·mg-1) compared to the wild type. Mutant m5.7KB, which was generated from mutant m4.1KB1 treated using EMS, had its transesterification activity decreased to only 0.051 U·mg-1. Mutant m6.0,3KB2, which was resulted through NMNG treatment, experienced an increase in transesterification activity which was 91.2% higher than that of KB.Keywords: ethyl methane sulfonate, lipase, mutant fungi, N-methyl-N’-nitro-N-nitrosoguanidine, ultraviolet ABSTRAKLipase dimanfaatkan salah satunya dalam produksi biodiesel, yaitu dalam reaksi transesterifikasi.

Production of Xylanase by Recombinant Bacillus subtilis DB104 Cultivated in Agroindustrial Waste Medium
AbstractA recombinant Bacillus subtilis DB104 strain harbouring recombinant plasmid pSKE194 containing an Open Reading Frame (ORF) of endoxylanase and its indigenous promoter from the wild-type B. subtilis AQ1 strain was constructed. This recombinant B. subtilis DB104 strain had higher endoxylanase activity than the nonrecombinant B. subtilis DB104 strain in standard media, such as Luria Bertani (LB) and LB with xylan. The agroindustrial wastes corncobs and tofu liquid waste were chosen as cost-effective carbon and nitrogen sources, respectively, to test the economics of xylanase production using the recombinant B. subtilis DB104 at a larger scale. Submerged fermentation using a 4.5 L working volume fermentor with tofu liquid waste and 4% corncobs produced maximum xylanase activity of 1296 ± 1.2 U/mg (601.7 ± 0.6 U/mL) after 48-hour fermentation at 37°C with 150 rpm agitation; this is more than twofold higher than the activity produced in an Erlenmeyer flask. This is the first report of high xylanase activity produced from recombinant B. subtilis using inexpensive medium. During fermentation, the xylanase degrades corncobs into xylooligosaccharides, showing its potential as an enzyme feed additive or in xylooligosaccharide production
