Cassava starch (Manihot esculenta) is polysaccharide compound which comprises of amylose and amylopectin. This paper demonstrated the characterization result of cassava peel waste modified by esterification with acetic acid and oleic acid. The products were analyzed by FT-IR, PSA, SEM, and XRD. FT-IR results represented carbonyl compound. DS value of acetic acid and oleic acid modification is 0.63 and 0.56, respectively. Characterization by PSA found the distribution frequency was 358.19 mm. SEM analysis was obtained rigid structure. From XRD result, the crystallinity of modified flour better than without modification.

Indonesia is the second biggest producer of natural vanillin. Traditionally it was isolated from the bean of vanilla (Vanilla planifolia Andrews). This paper reports on applying vanillin as starting material for synthesizing a biologically important chemical structure 3,4-dihydropyrimidinone. The reaction was undertaken in one step following multi component reaction (MCR). Products determination was undergone using FTIR and UV-Vis spectrophotometry, and also liquid chromatography-mass spectrometry (LCMS). After purification under flash column chromatography in ethyl acetate-hexane, it was found a white solid of 4-(4-hydroxy-3-methoxyphenyl)-6-methyl-3,4-dihydropyrimidin-2(1H)-one in 67% yield with a few amount of an unreacted vanillin.

Synthesis of Patchouli Biochar Cr2O3 Composite Using Double Acid Oxidators for Paracetamol Adsorption Tutik Setianingsih; Masruri Masruri; Bambang Ismuyanto

Composite built by patchouli biochar and metal oxide, Cr2O3, is a potential material for remediation of contaminated wasterwater. Oxidation of biochar using acid or salt oxidators can improve its surface polar functional groups. This treatment may be able to increase impregnation of metal cation (as salt) before calcination to form its oxide. In this research, 3 types of oxidators were used to oxidize the biochar before impregnation with purpose to study its influence toward physichochemistry and adsorption performance of the composite. Preparation of the composite included 3 steps, including preparation of biochar by pyrolisis of patchouli biomass using ZnCl2 activator at 450 oC, oxidation of the biochar using 3 different oxidators (H2SO4-HNO3, H3PO4-HNO3, H2O2–HNO3) at 60 oC, impregnation of the oxidized biochar using CrCl3 followed by calcination process to form biochar–Cr2O3 composite at 600 oC. Characterization using X-ray diffraction indicated that the composite containes the Cr2O3 structure. FTIR spectrophotometry characterization indicates the different content of C=O, C-O, and –OH on the composite surface. SEM images shows irregular micro ball shapes. EDX characterization indicates the different Cr content in the composite with same sequence with FTIR absorbances of both C-O and –OH. Adsorption of paracetamol indicates effect of Cr2O3 showing the same sequence of both.

This research aims to know the effect of the use of powder moringa seed to coagulant mass and coagulation process, and its effectiveness to increase the quality of pure water. This research uses factorial research design and statistic test MANOVA. To analyse water quality, the researcher uses Fe parameter. A graphic of coagulant mass and time for each parameter is used to analyse the data. Based on the research result, the uses of moringa seed as coagulant in each 300 mL mineral water gives a possitives result to the river water sample using 100 mg coagulant mass and sedimentations time for 60 minutes, well water sample using 500 mg coagulant mass and sedimentations time for 60 minutes, tap water sample using 300 mg coagulant mass and sedimentations time for 90 minutes. The effective coagulant that increase the water quality on well water is 98,32% of moringa seed powder, on river water is 96,64% and for tap water is 25,62%.

Polyaniline (PANI) is a conductive polymer and potential for application in the electronic device manufacturing. This paper discloses a recent strategy in synthesis polyaniline nanoparticle (NP-PANI) using inverse micelle (IM) microemulsion method, and also characterization of the provided products. The synthesis step was conducted by mixing of aniline as a polymer precursor with PEG 400, n-hexane, n-butanol, ammonium persulfate and hydrochloric acid in three different reaction times, i.e. for 2, 6, and 12 hours at 26 oC. NP-PANI was afforded as a brown powder in 2.87%, 1.97% and 2.30% yield for NP-PANI-IM-2, NP-PANI-IM-6 and NP-PANI-IM-12. The characteristic on ultra violet-visible and infrared spectra exhibited NP-PANI was formed as an emeraldine salt oligomer. Moreover, their morphology was observed through scanning electron microscopy (SEM) and showed a different range of nanoparticle size, i.e. 50-62, 68-72 and 58-62 nm for NP-PANI-IM-2, NP-PANI-IM-6 and NP-PANI-IM-12, respectively. These products open the potency application in material science.

This study looks at the wastes derived from Indonesian fruit as prospect for biofuels. This report investigates the chemical composition of Srikaya (Annona squamosal sp.) seed, which is disposed as waste products from traditional markets. The seeds were extracted with various extraction methods and the oil obtained was analysed by means of gas chromatography (GC/FID), gas chromatography-mass spectrometry (GC/MS), infra-red spectrometry and ultra-violet-visible spectrometry. It was found 2 h extraction using soxhlet apparatus with diethyl ether as solvent gave the optimum time extraction. Moreover, five major components were isolated from i.e.: ethyl hexadecanoate, ethyl hexadec-9-enoate, ethyl octadecanoate, 2-hydroxy-1,3-propanediyl hexadecanoate, octadec-9-enaldehyde, and unknown compound, respectively.

White ginger which is also called Jahe Putih (Zingiber officinale) in Indonesia, is widely used in local Indonesian communities. It is a popular ingredient in beverages for stamina and also a bioactive ingredient for many traditional Indonesian food recipes. It is a popular ingredient in beverages for stamina and also a bioactive ingredient for many traditional food recipes. However, with the increase in demand for ginger related products, fake ginger formulated products are widespread in the market. This paper is disclosed the chemical profile of essential oil obtained from steam distillation of the local ginger. The results of this study can be used as a standard to detect original ginger. It was found that the chemical composition of the essential oil obtained from the white ginger contained 0.19% of a dried weight after 3 h of steam distillation. A total of 40 monoterpenoids (C10) and sesquiterpenoids (C15) secondary metabolite compounds were respectively detected in the oil.

The organic-agricultural waste resulted from local farmer or community gardening recently paid public attention. The presence and easily grown of “Lidah Mertua” or Sanseviera trifasciata being focused on potency investigation for its prospecting application. It was reported contain some phenolic and also tannin extracted from aqueous solvents. This paper revealed recent investigation applying of its isolated tannin from leave part to modifying of activated carbon. The previous report published that carbon were able to adsorb some toxic heavy metals. However, it has some limitation including lower capacity adsorption. Impregnated or immobilized the tannin-isolated from S. trifasciata leaves was able to modify the carbon functionality, physical appearance, pores size, and it adsorption capacity. Both Langmuir and Freundlich adsorption mechanism model also disclosed the developed adsorbent mechanism of iron(II) adsorption on the adsorbent tannin-immobolized on carbon. The real test using community well drilling water source also gave important finding on the concentration of iron(II) contained on water source.
