Any laundry operation will discharge the waste water directly to the water surface, which can lead to pollution in the water. One method that can be used to treat laundry wastewater is a photocatalytic method with TiO2 (Titanium Dioxide) as an UV-assisted catalyst that is combined with a strong H2O2 oxidizer to produce OH (hydroxyl radical) to oxidize pollutants. The study aims to determine the differences in pH, TSS, BOD, COD, and Phosphate separation values with combination of TiO2 and H2O2 doses with variations in UV exposure time for 30, 60, and 90 minutes. A good quality TSS level obtained in the 60th minute with a dose of 1 g TiO2 and in combination with 10 ml H2O2 can reduce TSS levels by 20 mg/l from the initial TSS with a residual weight of 180 mg/L. A decrease in the quality COD level at a 90 minute clearance time with a dosage of 1 gr TiO2, in a combination of 10 ml H2O2, can reduce the COD levels by 32.5 mg/ l from the original COD value of 89.1 mg/l. A reduction in the phosphate level achieved at the cleaning time of 30 minutes at a combined dose of 4 gr TiO2 in a 40 ml combination, can lower the phosphatic level by 0.05 mg /l from the starting value of 5.61 mg/l and already meet the quality standard of laundry waste water.

Pollution of dug well water in Gampong Jawa Banda Aceh is caused by an imbalance in the ecosystem of organic and inorganic pollutants. The purpose of this study was to determine the effect of chitosan biocoagulant as a dug-well water purifier. The stages of this research were making chitosan from shrimp shells, making chitosan biocoagulant with the addition of 1% CH3COOH, and coagulation and flocculation with various biocoagulants (0.1%, 0.2%, and 0.5%) using the jar test method with fast stirring at 150 rpm and slow stirring at 50 rpm. The results of FTIR research on chitosan were characterized by the loss of the C=O group in the deacetylation process to change the acetyl amino group in chitin to amino, with a degree of deacetylation of 93.27%. The optimum performance of biocoagulants at a concentration of 0.5% can reduce pH from 7.1 to 6.9, the turbidity level to 99.99% (NTU), and E. coli to 0 jml/mL. The conclusion from this study is that chitosan biocoagulants are able to reduce turbidity levels (NTU), pH, and Escherichia coli bacteria.

Castor seed oil (Ricinus communis L) can be utilized for the manufacturing of membranes reacted with toluene diisocyanate (TDI). The aim of this study was to examine the effect and membrane characteristics of castor seed oil with a combination of silica used as an adsorbent, with a combination of silica (SiO2) 0.5 mg, 1 mg, 1.5 mg, and 2 mg. The initial analysis of the membrane was carried out with a swelling test of 1.5 mg of silica variation to obtain the most ideal result of 200%. The best chemical resistance characterization occurred at a variation of 1.5 mg of silica. Further characterization, particularly the FTIR test, thermal test, mechanical test, and SEM test, showed that there were Si-O groups and amine groups (NH2), and on the membrane there were groups OH, C=O, and NH. The thermal characterization of the silica membrane (1.5 mg) gave the greatest residue concentration, measuring 3.2%. In mechanical terms, the silica membrane has a higher elongation value than the membrane. In SEM characterization, the silica membrane has holes and is solid. This study indicated that the highest drop in Fe metal occurred at an immersion period of 6 hours with a combination of silica with a flux value of 9.25 L/m2 hour and a rejection value of 0.098%.

Development of drug delivery systems (DDS) has been widely carried out using safe biopolymers – starch and κ-carrageenan. However, for optimal use, the foregoing polymers still suffers from mechanical weakness. Combining both polymers could enhance the properties of each of the polymer. This research aimed of improving the applicability of starch and κ-carrageenan as DDS by means of polyelectrolyte complexation to form a polymer film. The composition ratio of starch:κ-carrageenan was optimized using response surface method (RSM) on Design Expert 11.0 based on water swelling, tensile strength, and disintegration time of the film. Fourier transform infrared spectrometry was performed on the prepared starch—κ-carrageenan film and suggested the successful film preparation. The bulk characteristics of the film are dependent on the starch or κ-carrageenan composition ratio, where starch has been associated with higher thickness, while κ-carrageenan — rigidity. From the RSM, the optimized composition was revealed to be 2.95 and 2.84 g for starch and κ-carrageenan, respectively, in a 60 mL aqueous solvent. The predicted optimum properties of the film were 160.21%, 3.26 MPa, and 17.47 min for swelling degree, tensile strength, and disintegration time, respectively. Taken altogether, the characteristics of starch or κ-carrageenan individually could be modified by polymeric combination, where they could be optimized by means of RSM.

Even though phytoremediation is considered a green technology for remediating heavy metals, there are some problems with the application of this technology, particularly when it comes to managing the biomass that is used. So, processing biomass needs to be given a lot of attention. This study outlined the utilization of extracts obtained from the hyperaccumulator plant Brassica oleracea var. alboglabra to synthesize nickel oxide nanoparticles. Subsequently, the nanoparticle underwent testing to determine its suitability as an absorbent for heavy metals, specifically lead, as well as its efficacy as an antifungal agent against Fusarium sp. strain. The characterization of nickel oxide nanoparticles involved several measurements, such as scanning electron microscopy analysis, high- and low-resolution transmission electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and hysteresis curve acquisition. The research findings indicate that the extract from hyperaccumulators can be utilized for the synthesis of NiO, which exhibits an absorption capacity exceeding 98% and serves as an efficient antifungal agent against Fusarium sp. pathogens. The approach utilized in this study not only prioritizes "green" and sustainability factors but also takes into account the economic aspects associated with the items being manufactured. The research has important implications in two areas. Firstly, it demonstrates the utilization of natural resources (B. oleracea var. alboglabra) in the production of nickel oxide, which serves as a safer and more eco-friendly substitute for dangerous chemicals. Furthermore, it aids in the advancement of novel techniques for effectively managing biomass hyperaccumulators.

3D printing technology is one of the latest innovations in the manufacturing industry. One of the uses of 3D printing is manufacturing products and machine components such as making coupling components on the Z axis of a 3D printer machine. 3D printing technology works by extruding thermoplastic filaments to form layers of material gradually. In this research, the filament used is PLA (Polylactic Acid) filament with a diameter of 1.75 mm. This research aims to analyze the effect of process parameters on surface roughness using response surface methodology (RSM). The parameters tested were nozzle temperature (215°C, 230°C, 245°C), layer height (0.2 mm, 0.25 mm, 0.30 mm), and print speed (50 mm/s, 65 mm/s, 80 mm/s). The results showed that nozzle temperature and layer height significantly influenced the surface roughness results. The most optimal process parameters to minimize surface roughness are at nozzle temperature of 249°C, layer height of 0,17 mm, and print speed of 90 mm/s.

The study is conducted to analyse foods which are marketed in Aceh since March 2015. Within 3 months of observation, the study took in total 98 samples, 18 of which are positive for borax content. Food types commonly containing this dangerous substance are yellow noodle, fried tofu ball with peanut sauce, and fried meatball, with borax determination using indicator turmeric. The assumption is a significant correlation between motherâ€™s educations to high level consumption of borax containing foods for children in Aceh, since the average motherâ€™s educations in Aceh are low. Therefore, several factors in motherâ€™s educations need to be revealed. The study area is focused on the area of Aceh Besar Regency, where cases for the borax containing foods were highly found. The data used in this study are data findings for the use of borax in Aceh Besar Regency, the observation of motherâ€™s education through social media, deep interview to several housewife mothers, several public figures and several communities with knowledge in local customs, in addition of observation on object related to the use of boraxs. The interview result is inserted to a matrix table in order to obtain information related to motherâ€™s education. The analysis is done in descriptive-qualitative method. One of the study results shows a correlation between motherâ€™s educations to children foodâ€™s consumption. The better motherâ€™s education will lead to healthier children foodâ€™s consumption. Environmental factors also play a role.
