The environments have created an abundance of residual plants from all life sectors, which is not optimal for bioethanol. Therefore, this research developed microbial technology that yielded sugar and fermentation testing. The research aimed to discover the delignification process and compare the consuming sugar by Saccharomyces cerevisiae between the chemical saccharification and accelerated bio-agent of fungal consortium in the engineered media. The innovation of the bioethanol process was conducted using raw materials from biomass. Based on this study, some preliminary hypotheses were made: (i) arranging fungal substrate which consists of residual sugar, molasses, and enriched residual papaya fruits could provide distinguishable growth of cell mass; (ii) the substrate concentration of 2.5% and 7.5% in the growth medium using enriched residual papaya fruits, respectively, as a medium, could be distinguished using delignification. A benchmark was used to compare the chemical and bio-agent saccharification. The consortium that grew and produced cell mass by times factor in molasses has fulfilled the element needed compared to the natural organic substances from the papaya fruit. The higher concentration of delignification material substrate yielded higher growth-saccharification and the average of 10.45 ± 0.21 % Brix was obtained by the fungal consortium in the broth medium, although the acceleration growth is insignificant. Nonetheless, Saccharomyces cerevisiae had successfully fermented saccharification yield sugar from the delignification of plants residual

Both solid and liquid residues derived from activity of particleboard (PB)’srecycling were investigated. The solid was attempted to make recycle particleboard (rPB) while the liquid was tried to use as fertilizer to seedling of Acacia crassicarpa. Objective of this study was to compare quality between PB and rPB and to evaluate seedling growth of A.crassicarpa exposed to liquid disposal from PB’s recycling activity. Methods of this study were consisted of testing of physical and mechanicalproperties of industrial PB, manufacturing rPB, and comparing the properties between PB and rPB. Prior to manufacture rPB, liquid disposal from PB’s recycling activity was released through water immersion of industrial waste’s PB comprised of predominant trimming residues. The liquid disposal was measured its nitrogen (N) content and then it was kept in a gallon for further use as fertilizer. Observation on growth parameters (height, diameter, leaves number and seedling’s strength) of both treated and untreated seedlings was conducted weekly for 2 months. Results of this study showed: 1)rPB was feasible to be produced but their quality was slightly decreased. 2) Liquid disposal during cyclist test and water immersion of PB’s residues contained 0.69% N. 3) Growth parameters of A.crassicarpa seedling showed response positively and significant statistically between treated and untreated seedlings. These findings suggested that both residues originated from PB’s recycling can be utilized further; the solid can be used as raw material of rPB while the liquid can be utilized as fertilizer to seedlings.

Self-regulation online learning (SRoL) merupakan proses proaktif secara internal dari mahasiswa untuk dapat mencapai perkuliahan yang dilakukan secara online dimasa pandemi covid-19. Tujuan dari penelitian ini adalah menggambarkan kondisi perkuliahan mahasiswa dimasa pandemi yang mengubah regulasi belajarnya, dan bagaimana capaian-capaiannya. Metode penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan mengambil teknik random sampling pada mahasiswa yang aktif dalam perkuliahan online. Deskripsi hasil penelitian ini menerangkan capaian tertinggi dari respons self regulation online learning (SRoL) meliputi enam indikator yaitu pertama goal setting menunjukkan 57,1% mahasiswa dapat membuat strategi belajar dengan baik. Indikator kedua environment structuring yaitu bagaiamana mereka mengatur lingkungan secara kondusif direspons 35,7%. Indikator ketiga task management direspons 7,1%, indikator keempat time management menerangkan sebanyak 32,9% mahasiswa dapat mengelola waktunya. Kelima help seeking yaitu meminta bantuan teman 80,1% dalam mengerjakan tugas atau memerlukan pemahaman. Keenam self evaluation direspons 44,3% yaitu mahasiswa mengevaluasi hasil belajar dengan capaian pembelajarannya. Dari data ini menunjukkan pencapaian perkuliahan yang dilakukan dengan sistem online tidak menjamin adanya usaha yang maksimal meskipun dapat mengakses tugas-tugas perkuliahan lebih mudah dengan jaringan internet.
