Abstract

The most effective way to reduce the pollution of heavy metal waste is the adsorption process using an adsorbent. Sugarcane bagasse is one of materials that has high affinity to absorb heavy metals. The adsorption capacity of sugarcane bagasse can be increased by converting it into cellulose xanthate by reaction of cellulose with carbon disulfide (CS2). Synthesis of cellulose xanthate consists of three stages, i.e isolation, alkalization, and xanthation. In this study, the preparation of cellulose xhantate was conducted by adding carbon disulfide (CS2) about 180% (w/w). The temperature of xhantation reaction was varied at 35C, 40C and 45C. The effect of temperature reaction into degree of substitution (DS), the degree of polymerization (DP) and the metal adsorption capacity of cellulose xanthate for Zn2+ and Pb2+ were determined by quantitative and qualitative analyze. Morphological characteristics of cellulose xanthate was characterized by SEM and the functional groups contained in the cellulose xanthate was characterized by FTIR. The result showed that cellulose xanthate synthesized at temperature of 35C have a highest value of DS, DP, and the adsorption capacity higher than two variations of temperature (40C and 45C). The value of DS, DP, and the adsorption capacity is 0.389, 299.27, 48.353 mg/g for Zn2+ metal and 51.763 mg/g for the metals Pb2+, respectively

Abstract

Zeolit Lynde Type-A (LTA) merupakan zeolit yang tergolong dalam kadar Si/Al rendah. Zeolit LTA memiliki berbagai kegunaan, antara lain sebagai adsorben, katalis, membran, penukar ion, maupun molecular sieve. Zeolit LTA sebagai molecular sieve memiliki kemampuan dehidrasi yang tinggi sehingga dapat digunakan untuk dehidrasi air pada campuran bioetanol-air agar diperoleh bioetanol yang sesuai dengan FGE (Fuel Grade Ethanol), yaitu kemurnian mencapai lebih besar dari 99%. Zeolit LTA dapat menyerap air di dalam bioetanol dikarenakan sifat Zeolit LTA yang hidrofilik. Penelitian ini mengkaji pengaruh waktu aging agar diperoleh persen kristalinitas relative zeolit LTA yang tinggi. Variasi waktu aging pada penelitian ini adalah 0 jam, 15 jam, 30 jam, dan 45 jam. Tahapan sintesis zeolit dilakukan pada sebuah water bath secara hidrotermal dengan metode step change temperature, yaitu pada suhu 90oC selama 1,5 jam dan 95oC selama 2,5 jam. Hasil sintesis dianalisis menggunakan SEM (Scanning Electron Microscopy), FTIR (Fourier Transmission Infra Red), BET (Brunaur, Emmet And Teller), dan XRD (X-Ray Diffracton). Berdasarkan analisis FTIR, hasil sintesis mempunyai ciri khas Zeolit LTA yaitu double rings pada bilangan gelombang 550-600 cm-1, persen kristalinitas relatif tertinggi yang didapatkan dari hasil analisis XRD adalah sebesar 66,15%, hasil analisis SEM menunjukkan morfologi Zeolit LTA berbentuk kubus, dan berdasarkan analisis BET didapatkan isotherm adsorpsi tipe ketiga.

Abstract

Telah dilakukan penelitian penggunaan material aluminasilikat MCM-41 sebagai adsorben limbah cair tapioka. Dalam penelitian ini dipelajari permodelan isotermal dan kinetika adsorpsi dari material MCM-41 pada proses adsorpsi limbah cair tapioka. Isotermal Langmuir dan Freundlich digunakan sebagai permodelan isotermal data penelitian. Dari data penelitian yang diperoleh pada konsentrasi COD sebesar 416 - 784 mg/L, proses adsorpsi limbah cair tapioka oleh MCM-41 sesuai dengan pendekatan isothermal Langmuir. Kapasitas maksimum adsorpsi MCM-41 diperoleh dari pendekatan Langmuir adalah sebesar 15,92 mg/g. Model kinetika pseudo-orde pertama dan pseudo-orde kedua digunakan untuk analisis kinetika adsorpsi pada data penelitian. Model kinetik pseudo-orde pertama yang sesuai dengan proses adsorpsi limbah cair tapioka dengan laju penyerapan adalah 7,48 x 10-2 dan 7,37 x 10-2 g/(min-mg) untuk konsentrasi awal secara berturut-turut adalah 608 dan 784 mg/L.

Abstract

Tujuan dari penelitian ini adalah untuk mengevaluasi hubungan antara Digital Intellectual Capital dan Inovasi berkelanjutan dan Kinerja Keuangan. Studi ini mempertimbangkan peran yang dimainkan oleh transformasi digital dan mediasi reputasi perusahaan. Teknik pengambilan sampel menggunakan purposive sampling. Terdapat 122 sampel dari 15 perusahaan industri barang konsumsi primer yang terdaftar di Bursa Efek Indonesia. Penelitian ini menggunakan data sekunder yaitu laporan keuangan tahunan perusahaan yang diperoleh dari website resmi perusahaan yang dijadikan sampel tahun 2019-2023. Data yang digunakan adalah laporan keuangan tahunan perusahaan, yang diolah menggunakan metode Partial Least Square Structural Equation Modeling (PLS-SEM). Hasil penelitian menunjukkan bahwa Digital Intellectual Capital memiliki pengaruh positif dan signifikan terhadap Kinerja Keuangan, serta hubungan tersebut diperkuat oleh DT sebagai variabel moderasi. Sebaliknya, Inovasi Berkelanjutan tidak memiliki pengaruh signifikan terhadap Kinerja Keuangan maupun Reputasi Perusahaan. Reputasi Perusahaan juga tidak memediasi hubungan antara Digital Intellectual Capital dan Kinerja Keuangan, serta antara Inovasi Berkelanjutan dan Kinerja Keuangan. Namun, Reputasi Perusahaan memiliki pengaruh positif signifikan terhadap Kinerja Keuangan, menegaskan pentingnya reputasi perusahaan dalam meningkatkan kinerja keuangan.

Abstract

This study aims to determine the strategies teachers use in carrying out independent learning curriculum learning in frontier, remote, and disadvantaged schools and to explain the limitations in frontier, remote, and disadvantaged areas. The method used in this research is qualitative with a case study approach. This research was conducted at SMP Negeri 2 Amandraya in South Nias district, North Sumatra province. Data collection techniques were carried out through interviews, observation, and documentation. Informants in this study consisted of 10 teachers, principals, and 20 students. Data analysis was done using data reduction, presentation, and conclusion. The results of the study show that the teacher's strategy in implementing the independent learning curriculum in frontier, remote, and disadvantaged areas is that the teacher optimizes the use of available learning facilities, the teacher utilizes learning tools and materials that are made naturally, and the teacher uses internal creativity in supporting learning by independent learning curriculum. Teacher competence in implementing the independent learning curriculum has limitations, namely the need for teacher training and professionalism. In addition, the results of implementing the independent learning curriculum have yet to experience changes in student learning outcomes fully. Therefore, the researchers suggest that local governments focus on developing human resources and learning facilities in frontier, remote, and underdeveloped regional schools to create young people who can compete nationally and internationally.

Abstract

Pupuk organik cair adalah pupuk yang terbuat dari bahan-bahan organik alami seperti sisa-sisa tanaman, hewan, atau limbah organik yang difermentasi serta dapat diaplikasikan dalam bentuk cair. Bahan baku yang digunakan dalam pembuatan pupuk organik cair sangat menentukan kualitas dari pupuk tersebut. Beberapa bahan baku yang dapat dijadikan sebagai pupuk organik cair diantaranya adalah daun tithonia (Tithonia diversifolia), daun kaliandra (Calliandra calothyrsus), serta limbah kulit pisang. Penelitian ini bertujuan mengetahui kandungan unsur hara dalam berbagai pupuk organik cair. Penelitian ini dilakukan pada bulan Mei – Juli 2024. Penelitian ini terdiri dari 4 perlakuan pupuk organik cair, yaitu : 1). Daun Tithonia, 2). Daun Tithonia + Kulit Pisang, 3). Daun Kaliandra, 4). Daun Kaliandra + Kulit Pisang. Variabel yang diamati pada penelitian ini adalah Ph, C-organik, kadar hara makro (N,P,K,). Data yang dihasilkan dianalisis dengan membandingkan hasil variabel pupuk organik cair yang diamati dengan persyaratan teknis minimal pupuk organik cair sesuai dengan Keputusan Menteri Pertanian Republik Indonesia Nomor 261/KPTS/SR.310//M/4/2019. Hasil penelitian diperoleh kandungan hara N dan P tertinggi didapatkan pada pupuk organik cair daun tithonia yaitu N 0,081% dan P 0,020%. Sedangkan kandungan K dan C-Organik tertinggi diperoleh pada pupuk organik cair daun Tithonia + Kulit Pisang yaitu 0,280% dan 1,13%. pH tertinggi diperoleh pada pupuk organik cair kaliandra 3,97. Nilai kandungan unsur hara N, P, K, C-organik dan pH pada berbagai pupuk organik yang telah diuji masih belum memenuhi kriteria Permentan Nomor 261/KPTS/SR.310//M/4/2019
