Abstract

Liquid confectionery waste water treatment is carried out using a combination of batch system electrocoagulation methods and irradiation by UV light. The variations of contat time applied were 30, 45, 60, and 75 minutes, the electrode distance was 2 cm and voltage variation was 20 and 30 volts. In addition to reducing pollutant levels, UV lamps are also used to remove odors. The result showed that the electrocoagulation process and UV irradiation could reduce pollutant levels maximally at 30 volts 73 minutes. COD level decreased to 1646,40 mg/L (efficiency 76,34%) and TSS to 50 mg/L (efficiency 88,68%). UV irradiation is also effective in removing the odor of soft confectionery wastewater. This result meets the wastewater quality stabdard according to PerMenLH No. 5 of 2015 Appendix XXVI, it’s just that COD does not meet the quality standards, therefore further research is needed.

Abstract

The use of synthetic plastics in everyday life has a negative impact but can be reduced in effect, if replaced with biodegradable plastics. Polymer biodegradation can occur because of microbiological infestation of the material. Microorganisms could produce various kinds of enzymes that can react with polymers. This study aims to study the effect of adding organic matter spearhead bacteria on the biodegradation rate in test samples with the help of Bacillus sp bacteria and the bacterium Pseudomonas sp. In this case, bioplastic samples were characterized using Fourier Transform Infrared (FTIR) spectroscopy and continued with quantitative analysis using gravimetric methods to determine biodegradation rates based on CO2 weight. The results of the characterization test study showed that the test sample containing cellulose is characterized by the presence of glycosidic -OH, -CH, and C-O functional groups. The determination of the rate of biodegradation gave the value of the rate constant microcrystalline cellulose as a positive control of 0.0489 day-1, Bioplastic A without inoculum addition of 0.0451 day-1 while Bioplastic A with the addition of inoculum by 0.0423 day-1 . Meanwhile, Bioplastic B without inoculum addition is 0.0254 day-1, and bioplastic B with inoculum addition is 0.0391 day-1.

Abstract

This study aims to find the optimum conditions for the adsorption of Cr (VI) ion to the eugenol-silica gel composite as an adsorbent and to determine the adsorption parameters using the Langmuir and Freundlich isotherm model. The three optimization parameters analyzed were pH, contact time, and weight of the adsorbent of the eugenol-silica gel composite. The optimization experiment was designed using the Box Behnken Design Response Surface Methodology (RSM) on the MINITAB software. Then, the maximum adsorption capacity was evaluated using the Langmuir and Freundlich isotherm equation model. The results showed that the optimum conditions for the adsorption process were the weight of the eugenol-silica gel composite adsorbent of 0.15 grams, contact time of 35 minutes and pH of 5. The adsorption process under these conditions was favorable because the RL obtained was 0.0297. The maximum absorption capacity of Cr (VI) was indicated by the qm value of 1.0328 mg/g, and the KF, KL, and n values ​​observed 0.7961, 1.0885 and 14.0056, respectively. Adsorption of Cr(VI) ion by eugenol-silica gel composite followed the Langmuir isotherm equation.

Abstract

Corn stalks are an agricultural waste that is commonly found in Indonesia. Corn stalks have a high enough cellulose content which has functional groups that can be used as biosorbents. This study aims to optimize the adsorption of corn stalk waste to mercury metal ions and then determine the adsorption capacity and adsorption constant of the Langmuir and Freundlich isotherm model. This research begins with corn stalk preparation, delignification, characterization using FTIR and SEM, determination of optimization of biosorbent weight, pH of Hg solution, contact time, and concentration of Hg solution, then applied to mercury metal contamination waste. Optimization of the weight of biosorbent in the range 0.4-1.2 grams, pH of the Hg solution is 2-4, contact time is 60-120 minutes, and concentration of the Hg solution of 30-100 g/L with a solution volume of 50 mL. Furthermore, determination of mercury levels, manufacture of standard series, and testing using ICP-OES. Followed by the determination of Langmuir and Freundlich's adsorption isothermal model. The results of this study indicate that the optimum conditions for the adsorption process occur at the weight of the biosorbent 1.2 grams, pH of the Hg 3 solution, contact time of 90 minutes, and concentration of Hg solution of 40 ppb with a solution volume of 50 mL. The application of biosorbent to metal contamination waste with adsorbed Hg concentration obtained 27.5772 ppb in 50 mL of waste solution with an adsorption efficiency of 88.44%. In the determination of Langmuir and Freundlich isotherms, a match was found for Langmuir adsorption isothermals with an adsorption capacity of 0.00333 mg Hg/g biosorbent and b = 176.8256.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi rendahnya minat baca siswa sekolah dasar di Kecamatan Tawangharjo, Kabupaten Grobogan. Penelitian ini menggunakan metode kuantitatif dengan pendekatan survei, melibatkan 3817 siswa dari 29 sekolah dasar. Hasil penelitian menunjukkan bahwa hanya 10% siswa yang memiliki minat baca tinggi, 17% sedang, dan 73% rendah. Faktor-faktor utama yang mempengaruhi rendahnya minat baca siswa meliputi ketersediaan fasilitas baca, peran guru, dan dukungan orang tua. Sekolah dengan fasilitas baca yang lengkap dan guru yang aktif dalam kegiatan literasi memiliki siswa dengan minat baca yang lebih tinggi. Dukungan orang tua juga terbukti signifikan dalam meningkatkan minat baca siswa. Untuk meningkatkan minat baca, diperlukan pengembangan program literasi yang komprehensif dan keterlibatan aktif orang tua.

Abstract

Transformasi pendidikan di Indonesia merupakan upaya penting untuk meningkatkan kualitas dan hasil pembelajaran di sekolah dasar. Guru Sekolah Dasar (SD) memainkan peran sentral dalam proses ini melalui implementasi kebijakan Kurikulum Merdeka dan Program Guru Penggerak. Artikel ini meninjau literatur mengenai transformasi pendidikan oleh guru SD di Indonesia, dengan fokus pada kebijakan pendidikan, metode pengajaran inovatif, kepemimpinan transformasional, dan tantangan dalam implementasi. Studi ini menunjukkan bahwa kebijakan yang mendukung, metode pengajaran yang inovatif, dan kepemimpinan transformasional yang kuat dapat secara signifikan meningkatkan kualitas pendidikan dasar. Namun, tantangan seperti resistensi terhadap perubahan pedagogis dan beban kerja yang berlebihan perlu diatasi melalui dukungan administratif dan bimbingan yang memadai. Pengalaman internasional juga memberikan wawasan berharga tentang strategi sukses dalam transformasi pendidikan. Artikel ini memberikan rekomendasi untuk mendukung guru sebagai agen perubahan dalam meningkatkan kualitas pendidikan di Indonesia.
