Abstract

Tea waste is a low-cost alternative material for making adsorbent to remove methylene blue from synthetic dye wastewater perpetually. Optimization of the adsorbent process utilized Response Surface Methodology (RSM) and a continuously operating system in a fixed bed column. The independent variables in the research are X1 (bed height), X2 (contact time), and X3 (flow rate). The dependent variable is Y1 (removal efficiency) with a matrix design by Box-Behnken. The optimum condition of methylene blue (MB) B removal was found at X1=16 cm, X2=90 min, and X3=4 L/min with an adsorption efficiency of 90.45%. After the activation and adsorption of MB dye, the complete FTIR spectrum shows a distinct peak at 2933.7 cm-1. The results of the EDX analysis performed on tea waste reveal the presence of nitrogen (element N) following the adsorption process. This observation strongly suggests that the tea waste has effectively absorbed MB, as nitrogen is a constituent element found in the molecular structure of MB.

Abstract

.Bioethanol is a pure alcoholic compound consisting of ethanol and is produced through a biomass fermentation process with the help of microorganisms.  Making bioethanol can be done using plants that contain starch, carbohydrates, glucose, and cellulose. One option is kepok banana peels.  Utilization of kepok banana peels can increase the variety of raw materials for bioethanol production which are cost-effective and easy to obtain.  This research has been done before, what has never been done is the manufacture of bioethanol using various catalysts H2SO4, hydrolysis temperature and fermentation time.  This research method uses hydrolysis, fermentation and distillation with variations in hydrolysis temperatures of 80°C, 90°C and 100°C, variations in catalyst concentration H2SO4 1 M, 2 M, 3 M with fermentation times of 5, 7, 9 days. Results of this study  the highest yield and density were obtained at the hydrolysis temperature of 90°C, the catalyst concentration of 3 M H2SO4 with a fermentation time of 9 days was 5.0432% and 0.8346 gr/ml, and the highest bioethanol content was at the hydrolysis temperature of 90°C, the catalyst concentration  2 M H2SO4 with 9 days fermentation time of 0.2884%.  The size of a grade is influenced by the length of time of fermentation and the amount of catalyst given.  The density value of the bioethanol obtained meets the Indonesian National Standard.  The results of the GC (Gas-Chromatography) test based on the highest glucose content and fermentation time at each temperature variation showed that the bioethanol content with a glucose content of 5.2%, 12.2% and 14.1% respectively at a hydrolysis temperature of 80°C  , 90°C and 100°C with catalyst concentration H2SO4 3 M and a fermentation time of 9 days, namely 1.783%, 4.024% and 5.030%.  The greater the catalytic agent used, the greater the level of glucose produced and the longer the fermentation period given, the more optimal the product will be.

Abstract

Salah satu pencemar yang berbahaya dalam limbah buangan industri yaitu logam berat timbal (Pb). Adsorpsi sering digunakan karena prosesnya yang sederhana dan efektif untuk mengurangi kadar logam berat. Penelitian ini bertujuan untuk menganalisis efektifitas kertas HVS sebagai adsorben, menganalisis pengaruh waktu kontak dan massa adsorben terhadap kapasitas adsorpsi dan %removal serta mekanisme penyerapan melalui pendekatan isotermis adsorpsi Langmuir dan isotermis adsorpsi Freundlich.  Penelitian ini dilakukan dalam tiga tahap yaitu pembuatan adsorben, pembuatan limbah artifisial, dan proses adsorpsi dengan variasi massa adsorben dan waktu kontak. Hasil yang diperoleh menunjukkan bahwa % removal maksimum yaitu 95,41% pada massa adsorben 1 gr dan kapasitas adsorpsi maksimum yaitu 18.123,4 mg/g pada massa adsorben 0,05 gr, konsetrasi limbah 20 ppm dengan waktu kontak 120 menit. Mekanisme adsorpsi yang terjadi mendekati persamaan isotherm Freundlich dengan nilai R2 = 0,8746, diduga proses penyerapan terjadi secara multilayer. Semakin lama waktu kontak dan semakin banyak massa adsorben dalam konsentrasi limbah yang sama maka semakin rendah kapasitas adsorpsi dan semakin tinggi %removal Pb yang diperoleh.

Abstract

Palm kernel shell combustion waste in boiler units called fly ash (FA) is a low-cost alternative material as an adsorbent. FA contains high levels of silica (SiO2) and aluminium oxide (Al2O3). The content of both compounds is an important component as an adsorbent. FA was used to absorb methylene blue (MB) continuously from synthetic dye wastewater. The study was conducted by continuous system process optimization using Response Surface Methodology (RSM) Box-Behnken design. MB was flowed on a set of fixed-bed adsorption columns with independent variables in this study are X1 (bed height; 8, 12, 16 cm), X2 (contact time; 90, 120, 150 min) and X3 (flow rate; 2, 4, 6L/min). The dependent variables were Y1 (removal efficiency) and Y2 (adsorption capacity) with matrix design by Box-Behnken. Optimisation of MB removal in this study was obtained at X1 = 16 cm, X2 = 150 min and X3 = 2 L/min with removal efficiency of 98.45% and adsorption capacity of 0.115 mg/g. FA pores according to SEM analysis were obtained at 1-2 µm. Likewise, the results of EDX analysis showed that there were N and Cl atoms in FA after the adsorption process. This shows that FA is able to adsorb MB.

Abstract

Food insecurity affects every aspect of student development. Cultivating food security through education can be implemented through the culturization of food security in nature schools, and it is encouraged to be managed at the elementary level. Research relating to differences in the influence of nature school management on food security has not yet been found. This research aims to analyze the differences in the influence of general and Islamic school management on the culturization of food security. This research used a quantitative approach with a multivariate analysis of variance method using SPSS software. Data were collected using questionnaires of 20 items consisting of three aspects: school policy, learning activity, and student engagement. The participants were 28 principals and representatives in 15 nature elementary schools in West Java Province, Indonesia. The respondents were chosen from a population of nature elementary school principals using purposive sampling. The sampling encompasses the distribution of nature elementary schools based on types of school management and their distributive location. The result of the multivariate test shows a value of 0,260 0.05. This result means that different types of school management have an insignificant impact on the culturization of food security. The weakest aspect is school policy, with a mean score of 15.93, while learning activity and student engagement obtain a mean score of 27.25 and 27.50 for each. These findings imply that school policy in nature elementary schools must be improved to support a food security culture.

Abstract

Environmentally friendly plastics can be degraded biologically in an anaerobic environment. This plastic is synthesized from starch such as sago starch which is available in abundance. In the form of bioplastics, its mechanical properties are still not compared to conventional plastics derived from crude oil, so its application is limited. The incorporation of filler material increases its mechanical properties, one of the selected fillers is hemp fiber as used in this study. Thermoplastic starch from sago with flax fiber as a filler and the addition of Polypropylene to improve mechanical properties with a certain composition to maintain its natural biodegradability. The mechanical properties analyzed were tensile strength, elongation and modulus of elasticity. Water absorption tests were also carried out to observe the water resistance properties. The results of the tensile strength test showed that the best tensile strength value of 9.32 Mpa was obtained at the addition of 35% fiber with a TPS: PP ratio of 1:1.5. The same conditions were obtained for the percent elongation with the results of 10.16% and the modulus of elasticity was 91.73 Mpa. Water absorption showed that 55% filler gave the lowest water     absorption, namely 4.41% at a ratio of TPS: PP 1:0.5. The addition of fiber filler into the bio-composite affects the tensile strength,    elongation and modulus of elasticity, the higher the volume of filler entering the bio-composite, the lower the value of tensile strength, elongation and modulus of elasticity, or vice versa. The ratio of addition of polypropylene matrix is also influential, the higher the ratio contributes to the tensile strength, elongation and higher modulus of elasticity. High water absorption capacity will reduce the performance of biocomposite, so the lower the water absorption ability, the better the quality of the biocomposite product and the wider its application

Abstract

Sampah organik dapat memberikan manfaat apabila dikelola dengan baik. Salah satunya adalah pemanfaatan sampah organik menjadi pakan ikan dengan mengandalkan larva lalat BSF yang disebut Manggot yang mengandung banyak nutrisi untuk produktifitas ikan air tawar seperti lele.Tujuan kegiatan pengabdian adalah memberikan sebuah solusi kepada petani budidaya ikan air tawar di Desa Mon Geudong untuk penyediaan pakan ternak yang bernutrisi dengan harga yang lebih murah dibandingkan dengan pakan ternak konvensional dan juga menjadi salah satu usaha yang berkontribusi kepada pemanfaatan sampah organik menjadi bahan yang mempunyai nilai tambah (added value) dan menjadi salah satu potensi pengembangan ekonomi masyarakat yang akan berdampak pada peningkatan kebersihan lingkungan. Teknologi Biokonversi adalah sebuah proses yang mampu mengubah sampah organik menjadi produk pakan ikan yang berguna dengan memanfaatkan proses biologis dari mikroorganisme dan enzim. Teknologi ini dapat diimplementasikan oleh masyarakat desa binaan dengan pelatihan dan bimbingan serta dukungan untuk menyiapkan peralatan dan ruang untuk proses produksi maggot. Saat ini, produksi maggot dari BSF untuk pakan ikan belum ada di Kota Lhokseumawe dan Kabupaten Aceh Utara. Petani tambak memesan maggot di Banda Aceh, namun jumlah produksinya masih terbatas. Hal ini menjadi satu peluang bagi petani tambak ikan yang ada di Desa Mon Geudong. Teknologi ini tidak sulit diimplementasikan dan tidak mahal karena yang dibutuhkan adalah mengembangbiakan larva serangga BSF untuk menjadi maggot dengan bahan baku sampah organik yang telah dihaluskan. Satu siklus produksi maggot membutuhkan waktu sekitar 2 bulan didalam ruang penetasan dan pembesaran maggot sampai bisa dipanen. Ruang ini selanjutnya akan terus digunakan oleh kelompok pemuda memproduksi maggot untuk memenuhi kebutuhan pakan ikan mereka. Kedepan masyarakat juga berkeinginan untuk memproduksi maggot untuk dijual agar dapat memenuhi kebutuhan pakan ternak untuk Kota Lhokseumawe dan Kabupaten Aceh Utara. Desa Mon Geudong dipilih sebagai objek pengabdian karena desa tersebut sedang dalam perhatian khusus Badan Narkotika Nasional (BNN) yang sedang berupaya mereduksi peredaran dan penyalahgunaan narkoba dikawasan ini khususnya dikalangan generasi muda. Salah satu sebab tingginya kasus penyalahgunaan dan peredaran narkoba oleh generasi muda di desa ini adalah karena masalah ekonomi.
