Propionibacterium acnes is one of the bacteria that trigger acne. A popular face mask preparation today for acne skin care is the peel off Mask. The purpose of this study was to formulate ethanol extract of moringa leaves (Moringa oleifera L.) become a Peel Off mask preparation and see the antibacterial activity of the preparation against Propionibacterium acnes. This research method is quasi experimental, formulated Peel Off Mask preparation with variation of ethanol extract of moringa leaves F1 (10%), F2 (15%) and F3 (20%), then physical test (organoleptic test with hedonic scale 1-5, pH test, irritation test, spreadability test, dry time test) and antibacterial activity test with diffusion method. Data analysis of antibacterial activity test results using one way ANOVA test. The results showed organoleptic test, pH test, irritation test and drying time test F1-F3 all meet the standard. Antibacterial activity test has the greatest power is F1 17.17 mm. The result of one way anova test between F3 treatment with positive control 2 (peel Off mask Brand x®) obtained significance value (0.01) <(0.05), which means F3 has a significant difference to KP2. Conclusion; preparation peel Off Mask ethanol extract of Moringa leaves F3 is the best formula physically and has the greatest antibacterial activity of 17.17 mm (strong) against Propionibacterium acnes.

Kecapi (Sandoricum koetjape, (Burm.f.) Merr) leaf extract contains secondary metabolites such as alkaloids, flavonoids, phenolics and triterpenoids which may be an environmentally friendly corrosion inhibitor. The method used in extraction of kecapi leaves in 1 N hydrochloric acid as a steel corrosion inhibitor was carried out by weight loss, FTIR (Fourier Transform Infrared) and SEM (Scanning Electron Microscopy) methods. The data from the weight loss method revealed that the rate was inversely proportional to the concentration of the inhibitor and directly proportional to the temperature, while the value of the efficiency inhibition was directly proportional to the temperature and concentration of the inhibitor. The maximum efficiency inhibition value obtained was 86.61% at an extract concentration of 6 g/L and an immersion temperature of 60oC. The adsorption of kecapi leaf extract followed the Langmuir adsorption isotherm.

The present research was studied the capability of leaf dregs lemongrass (LDLG) and modified LDLG by Citric Acid (LDLGCA) for Cd(II) removal. The optimum conditions for both biosorbents at pH 5, stirring speed 200 rpm, contact time 60 minutes, and temperature 25 ᵒC. The optimum concentration LDLG was 120 mg/L and 160 mg/L LDLGCA with adsorption capacity 10.63 mg/g and 11.66 mg/g, respectively. Isotherm models revealed that the adsorption of LDLG and LDLGCA followed Langmuir isotherm model with coefficient determination (R2) 0.98 LDLG and 0.93 LDLGCA. Both biosorbents were fitted to pseudo-second-order indicating that adsorption process chemically occurring. Adsorption Cd(II) LDLG spontaneous reactions and exothermic, meanwhile for Cd(II) removal LDLGCA not spontaneous and exothermic. The characterization biosorbents was done using FTIR, XRF, SEM – EDX and BET. The adsorption capacity of both biosorbents decreased after 3 times adsorption-desorption cycles. Applications biosorbents to the real wastewater (Laboratory wastewater) indicated that LDLG can remove Cd(II) up to 46.88 % and LDLGCA reached the peak at 52.14 %. Based on XRF data, the percentage of Cd(II) in both adsorbents increased up to 21.12% for LDLG and 24.04 % for LCGA. The result indicated that Citric Acid was quite effective as modifier for Cd(II) removal.

Bone is an important support for the human body and is hard. To overcome damaged tissue, biomaterials can be used by implanting them into bone tissue. The material that can be used as a substitute for bone tissue is hydroxyapatite. The aim of this research was to synthesize porous hydroxyapatite from Clamshells using cassava starch polymer. In this research method, initially, CaO powder was obtained from clamshells in a furnace at a temperature of 800ºC for 3 hours after which XRF analysis was carried out. Next, the CaO powder was reacted with (NH4)2HPO4 with ratio mol Ca/P 1.67 and the pH was adjusted with NaOH to 12. Then, calcinated it at 900ºC, XRD and SEM were analyzed. Hydroxyapatite was mixed with cassava starch polymer with ratio of 10:1 at pH 11 with ammonia stirred at 300 rpm for 5 hours. Next, oven at 110ºC for 5 hours and furnace at 1100ºC about 4 hours. The results of the research were analyzed by XRD, FTIR, SEM, and Compressive Strength Test. XRD analysis on 1,67 mole Ca/P obtained hydroxyapatite compound according with ICSD No. 01-072-124. FTIR analysis shows the functional groups of O-H, P-O, and C-O. SEM analysis obtained particles in the form of non-uniform lumps. The compressive strength of HAp and porous HAp was obtained at 14.58 & 49.20 Mpa. This research concluded that porous hydroxyapatite from clam shells can be made from cassava starch polymer with good strength.

Squid ink (Loligosp) is still considered a waste and has not been widely used as a food ingredient. This study aims to determine the protein content of squid ink tested using the Kjedahl method and the level of iron (Fe) using Atomic Absorption Spectrophotometry with air-acetylene flame at a wavelength of 248.3nm. The squid ink used is obtained from the South Coast. Qualitative testing of protein was carried out using the biuret, ninhydrin, and xanthoprotein tests which showed positive results. In the test, iron was reacted with NH4OH to form a reddish-brown precipitate which indicated that it was positive for Fe. From the measurements obtained protein content of 14.0733% and Fe content of 3.8 g/g. This protein and iron content can be used to meet daily protein and iron needs so that squid ink can be used as a food intake

Inceptisol soil is a soil that is not good chemical and physical quality for the cultivation of lettuce microgreen. However, microgreen is a plant that has many benefits. Microgreens can fight free radicals, are useful as antioxidants, relieve the workload of damaged kidneys and lower bad cholesterol levels, and can reduce the risk of Alzheimer's disease. Several studies have been conducted to improve the soil quality of inceptisol. But improving its chemical quality by using a mixture of husk charcoal and sand and proving the change through the cultivation of lettuce microgreen has not been done much. The purpose of this study is to study the improvement of the chemical quality and physics of inceptisol soil using a mixture of husk charcoal and sand by cultivating lettuce microgreen in the land. This research is a mixture of field research and analysis in the laboratory. before planting and 2 weeks after planting, the land is measured pH, P determination is available by bra method, N conjecturing by means of distillation and spectrophotometry. Determination K uses HCl extraction method. Determination of Zn, Fe, and Ca using DTPA extraction. For analysis of cultivation, results is with RAK, where there are 4 groups with 5 Deuteronomy. The result was a change in pH from 4.7 to 6.9. The content of P, N and K changes from ineligible to fulfilling the requirements for lettuce plants. The results of the analysis provide real different information.
