The synthesis of mesoporous Al-MCM-41 material made into H-MCM-41 has been done by mixing 5 grams of Al-MCM-41 synthesis into 100 ml of 0.5 M NH4Cl solution, then filtered and washed and dried in an oven at temperature 80 oC for 24 hours. The acid sites contained in the mesoporous material of H-MCM-41 are the Brønsted acid sites (B) and Lewis acid sites (L). The mesoporous material of H-MCM-41 synthesis shows morphological form of hexagonal pore such as honeycomb. It also makes clear that CTAB as a pore structure steering agent has succeeded in forming a hexagonal phase pore from mesoporous H-MCM-41 synthesized material. The size of the pore diameter of the mesoporous material of H-MCM-41 synthesis was 2.88 Å measured using a measuring ruler based on the scale of the resulting image analysis using TEM.

A study has been conducted for functional group analysis of polyethylene Glycol (PEG) coated nanoparticles of iron oxide (Fe3O4) and biomolecules using FTIR-Spectroscopy. A sample functional group analysis was performed to determine the ability of modified iron oxide nanoparticles (Fe3O4) with the addition of PEG polymers, potentially to bind biomolecules. The presence of water molecules absorption on the surface of black iron oxide nanoparticles (Fe3O4) causing bonding with PEG polymer is indicated by the absorption peak at the vibration of the -OH (hydroxyl) group at the wave number 3441,01 cm-1. The result of modification of black iron oxide nanoparticles (Fe3O4) with PEG, can bind biomolecules exhibited repetition of the absorption peak on the vibration of the -OH (hydroxyl) group at wave number 3433,29 cm-1 and even the appearance of a new absorption peak on vibration CO at wave number 1350,17 cm-1

One method to eradicate plant pests carried out by farmers in the North Sulawesi area is to use pesticides because they are considered easy to obtain, the price is still affordable, and very effective at killing plant pests. However, improper use of pesticides results in the loss of pesticide residues in plants which causes environmental pollution, health problems in humans and inhibits trade. Therefore, it is necessary to monitor the use of pesticides through the fulfillment of the maximum residual limit (BMR). This study aims to analyze pesticide residues in tomatoes, cayenne pepper, and carrots using the method of High Performance Liquid Chromatography (HPLC) which was previously optimized and validated. The research samples were tomatoes, cayenne pepper, and carrots, taken from Pasar Bersehati Tomohon, Pasar Karombasan Manado, and Pasar Kawangkoan Minahasa, then taken to the Chemistry Laboratory of Manado State University to be extracted and analyzed. The results of this study indicate that pesticides with chlorpyrifos active ingredients were detected in almost all samples analyzed, although the levels were still below the specified BMR value, ie 1 mg/kg sample. The highest chlorpyrifos level was found in tomato samples taken from Pasar Kawangkoan Minahasa, which was 0.3150 mg/kg. The results of this study also showed that samples that were washed before extraction caused a decrease in the residual content of the petisides.

The purpose of this study was to identify compounds such as beta carotene, such as rubber extracts from various pumpkin strands extracts. Pumpkin plant as a minor food commodity, it is very rich in bioactive compounds that act as antioxidant very useful for human health. Strands in yellow fruit processing is often used as waste. This research was conducted by using laboratory analysis method through the following stages, determination and sampling, sample preparation, content analysis of beta carotene compound by spectrophotometer method at absorbance 445 nm. The results showed that strands of yellow pumpkin fruit contain beta carotene. In the extraction with Petroleum Ether (EPE), the beta-carotene content of EPE-strands 39.1 μg / g, ethanol extract (EET) of strands pumpkin flour, yielded 7.94 μg/g of beta carotene. The highest beta carotene content of the two extraction types EEP and EET are found in the extract with Petroleum Ether (EPE) because Petroleum Eter is a non-polar solvent which can dissolve less polar compounds that reside on cell walls such as terpenoids. Pumpkin fruit extract can be used as food fortification to increase the nutritional value.

The use of carbon steel to meet human needs is increasing every year. Steel is not a rust-resistant material, so it can corrode over time, especially Indonesia is a tropical country that has high rainfall and humidity. Almost all industrial sectors have problems with corrosion. Problems that arise can be in the form of damage, the age of use of goods that do not meet expectations until inadequate safety factors. This study aims to study the effect of low carbon steel coating composition using the PAni-TiO2 composite material. Coating of PAni-TiO2 composite on low carbon steel was carried out by the electrodeposition method on the acid medium and LiCl salt. TiO2 is synthesized by the sol-gel method, while PAni is synthesized by electrochemical polymerization along with electrodeposition. Based on the results of the study of the highest corrosion rate the Plate was produced without inhibitors with a value of 0.007359 mpy, while the lowest corrosion rate was produced by Plate 2 with a value of 0.003666 mpy. The best composition for protecting the Plate from corrosion is 10-3 M PAni and 10-2 M TiO2.

In this study, coconut fiber based activated carbon has been used for fabrication of supercapacitors. Iodine absorption test is performed to measured absorption level porous activated carbon sample size is relatively small (microporous). Characteristics of the activated carbon material covering the surface morphology and structure were tested using SEM and XRD. Electrode materials with composition (Activated charcoal: PVDF = 9: 1 (w / w)), the current collector and separator has been assembled to be tested its performance as an electrical charge storage device. The test results by cyclic voltammetry method was to look at the performance supercapacitor devices at once to obtain the value of the capacitance curve obtained voltammograms. Based on the results of the calculation of the capacitance, the highest capacitance values obtained in the supercapacitor with activated carbon electrodes in coconut fiber steam 50 mL / bar with a capacitance value is 50.73 F / g.

One of the processed coconut products that is beneficial to health and has been widely used as an industrial raw material is VCO. Traditional rural communities and households have produced their own VCO for personal consumption because of its health benefits. However, the production process of VCO which still traditionally produces VCO products with a standard of quality and yield that has not been maximized. The research was carried out by enzymatic method, which added the enzyme bromelain contained in pineapple stem extract into coconut milk. The VCO product obtained was then purified by zeolite adsorbent, and water content and free fatty acid levels were tested. The results showed the highest VCO yield was found at a concentration of 20%, which was 36% and the purification of VCO with adsorbent zeolite was proven to reduce water content and free fatty acid levels with the highest percentage decrease in water content by 66%, and the highest percentage decrease in free fatty acid 63%. From the results of the study it can be concluded that the addition of pineapple stem extract containing the enzyme bromelain in the production of VCO can increase the yield of VCO to a maximum of 35.9% and purification of VCO samples with adsorbent zeolite proven to help reduce water content and free fatty acid levels.

Manado Bay waters have a high diversity of seaweed. This study aims to find the seaweed in Manado Bay waters that have aglutinin activity. Seaweed samples were taken in Manado Bay. After cleaned and identified, the samples were extracted. The extract was tested on human red blood cells (erythrocytes) of 4 types (A, B, O and AB) with controls made without addition of extracts. The activity of agglutinin is determined by the agglutination titer of the highest dilution which causes cell agglutination. Agglutinin activity of each type of seaweed was tested at various temperature and pH. Among five species of seaweed that were tested, only three were agglutinated human red blood cells types A, B, O and AB. Halimeda macroloba and H. taenicola did not show any aglutinin activity. Based on the research, it can be concluded that Ulva fasciata seaweed, Halymenia durvillaei and Laurencia obtusa from Manado Bay waters have agglutinin activity.
