The aim of this study is to isolate and characterize the structure of metabolite compounds of the sponge Xestospongia testudinaria, which grows in West Kalimantan. 3000 grams of sponges were analyzed through a preparation and extraction process, which produced a methanol-dissolved extract with a mass of 77.2 grams. The methanol-dissolved extract of was parted using n-hexane and dichloromethane as solvents. Based on the results of phytochemical testing, it can be concluded that the dissolved fraction of dichloromethane contains alkaloids and terpenoids or steroids. The purification process was carried out on 2.4 grams of dichloromethane-dissolved fraction by means of vacuum liquid chromatography, and ten separation fractions were obtained with eluated ethyl acetate : n-hexane as eluent. The separation fractions of FD 3, FD 4, FD 5 and FD 6, which have the same chromatogram characteristics were combined to be purified by means of preparative chromatography. The preparative process was carried out with chloroform : methanol 98:2 eluent, and three chromatogram isolates were produced. The chromatogram isolates with Rf = 0.44 and a mass of 8 milligrams were analyzed by FTIR spectroscopy using pellet KBr and 1H-NMR spectroscopy using CD3OD solvent. Based on the results of data analysis, it is concluded that the predicted content of metabolite compound of the Xestospongia testudinaria sponge sample growing in West Kalimantan waters is propyl-6,7,8-trihydroxy-4-pentadecenoate compound, which is a compound of the fat or lipid ester group with a typical IR absorption peak of the C = O group and C – O at wave numbers 1735.93 – 1766.80 cm-1 and 1111.00 – 1315.45 cm-1 and the containing 11 environments of hydrogen atoms scattered in the 1H-NMR chemical shift from 0.85 ppm to 3.97 ppm.

Ale-ale are popular clams in the coastal area of Ketapang. The local community uses the clams as food, one of which is in the form of fermented products. In the fermentation process, the nutritional content of course will be different from fresh ale-ale because it has gone through the preservation process. One of the goals of processing it into fermented products is to increase the product's durability. Essential mineral contents (Fe, Mn, Zn) in fermented products is different and tends to decrease. Essential mineral testing used the Atomic Absorption Spectroscopy (AAS) method. The water content and ash content of fresh ale-ale were 63.1% and 15.8%, respectively. While the water content and ash content of the fermented ale-ale were 68.69% and 17.2%, respectively. The essential mineral contents of fresh ale-ale obtained Fe 23 mg/kg, Zn 1.70 mg/kg and Mn 0.138 mg/kg. In fermented ale-ale, the content of Fe is 9.76 mg/kg, Zn is 0.740 mg/kg and Mn is 0.387 mg/kg.

Peat water has different characteristics from one location to another. The characteristics referred to include levels of organic matter, pH, conductivity, and turbidity. Based on these differences, it is necessary to research to determine the analytic parameters and the effect of matrix differences on manganese levels using a separate calibration method and standard addition using a Uv-vis spectrophotometer. The determination of manganese was carried out by the persulfate method, that is the oxidation of Mn in water by persulfate in an acidic and hot atmosphere to form MnO4 which is purple-red. The obtained results from the determination of the analytical parameters of the separate calibration method are precision of 7.75% to 63.96%, an accuracy of 0.80% to 5.24%, the linearity of r = 0.997, a detection limit of 0.170 ppm, and a limit of quantification of 0.567 ppm. Meanwhile, the addition method produces a precision of 2.19% to 20.35%, accuracy and linearity at points I, II, III are 10.65% to 25.47% respectively; 20.9% to 26.8%; 2.76% to 27.24% and 0.995; 0.999; 0.995. Linearity in addition as well as in calibration curves at all points have met the minimum value of SNI 6989.5: 2009 (R ≥ 0.995). In addition, based on the results of the comparison of the levels of the separate calibration and standard additions, the values are different, but the results of the t-test result in t-count

Liquid smoke has been successful pabricated from mangrove Avicennia alba shell by pyrolysis method at a temperature of 400℃ for 3 hours. Liquid smoke was purified by adsorption using activated kaolinite as adsorbent. The test results showed that activated kaolinite could bring down the rancidness to become odorless and the color of liquid smoke from dark chocolate to gray colour. The composition of the liquid smoke compound was determined by using the Gass Chromatography-Mass Spectrophotometer (GC-MS) consists of 2-propanone (CAS) acetone 25.79% and furan, tetrahydro- of 10.37% and carbamic acid, monoammonium salt (CAS) ammonium carbamate of 58.46% . The LC50 value of pure liquid smoke ranging from 1000 ppm is an indication that it is not toxic and safe to use for food preservation. Activity test against the inhibition of microbial growth in fish meatballs, showed that ability. The higher the concentration of liquid smoke, the better the inhibition of microbial growth. Based on the results, it can be concluded that the liquid smoke produced from mangrove Avicennia alba shell purified by the activated kaolinite is very promising as a foodstuffs preservative

Photodegradation of phenol on TiO2-pillared-kaolinite was observed. Pillarization of kaolinite was conducted through intercalation of polyoxotitanium sol into clay suspension followed by calcination giving TiO2-kaolinite which showed an increase in specific surface area and total pore volume compared with the kaolinite. The analysis of XRD demonstrated no significant change on d-space of second order of kaolinite structure associated with 2q 26.61°, but diffractions with regard to 2q 25.3° and 48.0° interpreted for TiO2 anatase were seen on the diffractogram of TiO2-kaolinite. The significant decrease of phenol concentration was observed in the presence of both kaolinite and TiO2-kaolinite under UV illumination (hn ³ 365 nm) compare with the photoreaction without the kaolinite materials however the degradation rate of phenol on TiO2-kaolinite was faster than that on the kaolinite-only where 50% of phenol was consumed after 45 minutes of reaction. Kinetic study showed the photoreaction of phenol on TiO2-kaolinite follows the first order reaction with the reaction rate constant of 1.8 x 10-2 min-1.

Bath bombs were produced with ten different types of oil to determine the effect of the oil used on their physical and chemical properties. Bath bombs were prepared by mixing the dry ingredients first (citron, cornstarch, baking soda) and stirring until all the ingredients were well blended. Then, mixed the wet ingredients (water, oil, perfume ore, food coloring) into the beaker. After that, the wet ingredients were poured gradually into the dry dough, and this step was done until all the wet ingredients run out, and the texture of the bath bomb dough was slightly moist so that it can be put in the mold. Finally, the bath bomb is printed and tested in a laboratory. The result showed that the difference in essential oils used in the manufacture of bath bombs does not affect the pH of the bath bomb but affects the stability of the resulting foam. The acceptability test results showed that the resulting bath bomb provided a sensation of freshness and relaxation and did not cause allergies. Based on the SWOT analysis results, these bath bombs can advance and develop by implementing a vertical integration strategy

Virgin coconut oil (VCO) was prepared by stirring and cold-pressed methods. This research aimed to study the effectiveness of both methods on VCO extraction. The first method was carried out by high-speed stirring to broke the coconut milk emulsion, and the second method was using the freezing and thawing technique. The physical appearance of VCO from both ways was clear, with a specific odor and taste of fresh coconut oil. The density of the VCO obtained by the stirring and cold-pressed method was 936 kg/m3 and 933 kg/m3, respectively. Physicochemical characterization shows that the cold-pressed process produces better properties of VCO.

Research on the effect of variations in the composition of rice straw cellulose on the characteristics of biodegradable PET-Cellulose plastic. The purpose of this study is to explain the effect of the composition of rice straw cellulose and PET on the characteristics of biodegradable plastic made from composite of rice straw cellulose and PET. This research was conducted in several stages, the isolation of cellulose from rice straw, recycling PET from mineral water bottle, mixing cellulose and PET, then testing the characteristics, the DTA-TGA thermal characteristic test, and degradation test with the soil burial test method. . In the thermal characteristics test there was a decrease in weight in samples with composition PET: cellulose 90:10; 60:40; and 50:50 each with 0.719; 0.710; 0.581 mg in the temperature range 38.30-68.32 ° C, 40.72-68.17 ° C, 41.45-80.40 ° C, while in the samples 80:20 and 70:30 there was no decrease in weight the temperature. In the sample 90:10; 80:20; 70:30; 60:40 and 50; 50 there is a decrease in weight each of 4,045; 3,909; 3,464; 2,760 and 3,205 mg at temperatures 328, 16-430.65 ° C, 362.05-442.15 ° C, 349.96-439.82 ° C, 388.29-446.70 ° C, and 325.39-420.79 ° C. The degradation test using soil burial test method obtained percent weight loss in samples with PET composition: 70:30 cellulose which was 38.24%.
