Abstract
The production of soybean nationally is still low. Therefore, the expansion of agricultural land in Aceh can be applied to marginal lands, such as peatlands, swamps, tidal lands, and even land affected by the tsunami. This study examined the use of saline soil unaffected and affected by Tsunami for soybean (Glycine max var. kipas merah) cultivation by adding Arbuscular Mycorrhizal Fungi (AMF). Kipas merah was grown in unaffected and affected by Tsunami soil, with 0, 5, 10 and 15 g AMF per planting hole, in a Split plot with n=3, in a completely randomized layout. The results revealed that the dose of AMF affected all variables observed. The growth and yield of soybean increased as the AMF dose increased. AMF on land affected and not affected by the tsunami could increase the growth and yield kipas merah soybean variety. The application of AMF 15 g/plant and affected soil was the best treatment.

Abstract
Microgreens are quickly-grown greens that are suitable for urban areas. The accumulation of chlorophyll in plants is essential for both nutritional compounds and the microgreen’s attractive appearance. A plant factory is a controlled-environment cultivation method that employs LEDs to enhance photosynthesis, vegetative development, seed germination, and chlorophyll accumulation. This work used VIS-NIR for the quantitative determination of chlorophyll content in green and red spinach microgreens grown under four different LED light intensities with four different ratios, with 100% blue, red, and white LED, and 67%:20%:13% of red:blue: white LED, as artificial grow for 12 hours illumination. The performance of MSC, AN, SNV, smoothing, and the first and second Savitzky-Golay’s derivatives (SGD) were examined. PLSR explained accurately predicted R2C, R2P, RMSEC, and RMSEP up to 0.957, 0.892, 1.054, and 1.661 for chlorophyll a using SGD 1st; 0.813, 0.652, 0.979, and 1.338 for chlorophyll b using SNV; and 0.931, 0.876, 1.155, and 1.550 for total chlorophyll using SNV. The wavelength region of 400 to 700 nm was dominant based on the best regression coefficient (β) for predicting green and red spinach microgreens. Results demonstrated that VIS-NIR spectroscopy, combined with chemometric techniques, PLSR, can be used to evaluate the chlorophyll content of green and red spinach microgreens.

Abstract
The use of polyurethane membranes is inseparable from its several advantages, including the use of minimal energy, the use of fewer additional chemicals, and having good chemical resistance. The polyurethane membrane synthesized using red seaweed biomass (PUM-RSB) in this study was used as a filter in the ammonia filtration process in water. The specific objective of this research is to regenerate and test the chemical resistance of polyurethane membranes, in this study, an acid solution (H2SO4) and a salt solution (NaCl) were used for washing PUM-RSB, because it uses the principle of desorption from the ionic bonds formed or in other words ion exchange, characterization of functional groups shows that there is no change in structure, but a change in transmittance value (%T) between the polyurethane membranes before and after the washing process. The chemical resistance of PUM-RSB was evaluated in a solution of 3% HCl, 3% KOH, Aquadest, 50% Methanol, 5% NaCl, Fertilized soil and ordinary soil. PUM-RSB can be washed using 0.1N H2SO4 solution to regenerate the performance of the membrane, PUM-RSB tends to be resistant to some chemicals by experiencing weight loss of about 4-5% during one month of storage. The polyurethane membrane produced from red seaweed biomass has resistance to several chemicals, besides that the polyurethane membrane can be regenerated by a washing process. So that polyurethane membranes have the potential to be applied in various environmental conditions.

Abstract
Research has been carried out on hydrophobic membranes based on polyethersulfone (PES) polymers using Mg(OH)2 additives. PES membranes are made by blending polymers using Mg(OH)2 additive because structurally bound OH groups play an important role. In addition, Mg(OH)2 is also cheap and easy to obtain and non-toxic. This study aims to improve the performance of PES membranes, by studying the effect of adding Mg(OH)2 additives into the membrane system which was evaluated by analyzing changes in surface shape using scanning electron microscope, changes in chemical structure using ATR-FTIR, membrane porosity, and membrane mechanical properties. The performance of the membrane being reviewed is water permeability testing and rejection of organic compounds. The results of SEM photos showed that the addition of additives affects changes in the membrane structure, where large macrovoids formed on the modified membrane decreases the tensile strength of the membrane. Additives also increases the porosity of the membrane in the range of 12–40%. The addition of additives also leads to an increase in membrane performance, with a higher permeability of 56.4 L/m2·h·bar with 65% rejection. These findings indicate that PES ultrafiltration membrane with Mg(OH)2 additive can be used to reduce organic compounds in water.

Published: June 2023

Abstract
To increase the effectiveness of the coffee oil processing process in drying coffee beans, in this study, pretreatment drying using a microwave was evaluated. The drying method using a microwave was carried out with three power inputs. After the drying process, it was followed by roasting and grinding process of the coffee beans. Then the coffee beans were extracted so that the oil was obtained. From the process of drying coffee beans using a microwave with 3 variations of input power, namely MH, MM, and ML, from the initial moisture content of 56.75%, the moisture content was 7.29% in a row; 8.32%; and 10.32%. Meanwhile, from the results of the extraction of coffee beans in the three variations of the drying process, the yield of coffee oil was 16.936%, 16.448%, and 2.534%, respectively. It can be seen that the input power in the microwave drying process greatly affects the results of decreasing the moisture content of coffee beans and the yield of coffee oil. In addition, from the process that has been carried out, it can be seen that the fatty acid content obtained in coffee oil was high. So that the drying process carried out using a microwave is very effective to do in producing coffee oil with high yields.
