Pengembangan Kawasan Agropolitan dalam Perspektif Perencanaan Pembangunan Partisipatif. Penelitian ini bertujuan mengetahui dan memahami Pengembangan Kawasan Agropolitan dalam perspektif perencanaan pembangunan terutama berkaitan dengan akomodasi terhadap partisipasi masyarakat. Pengembangan Agropolitan merupakan bagian dari strategi percepatan peningkatan kesejahteraan masyarakat dan upaya pemerataan pembangunan daerah. Adanya Masterplan Pengembangan Agropolitan 2007 didukung oleh dokumen RPJMD Kabupaten Malang 2010-2015 menjadi pedoman dalam implementasi program tersebut. Kesadaran akan pentingnya akomodasi terhadap keterlibatan masyarakat mulai dari proses penyusunan hingga implementasi mendorong kesadaran urgensi adanya perencanaan yang lebih bersifat partisipatif. Dalam penerapan model perencanaan partisipatif secara tidak langsung memerlukan kehati-hatian dalam mengidentifikasi perwakilan masyarakat. Jika wakil-wakil itu cukup representatif, maka implementasi perencanaan tidak hanya menghasilkan partisipasi semu, namun bisa membawa manfaat bagi masyarakat secara luas.

A qualitative and quantitative analysis of the turpuntine oils was undertaken by means of gas chromatography and mass spectroscopy. Two types of sample was analyzed, one was bought from local market in Malang and a sample originally from local producer. Analysis was conducted directly from raw sample after drying over magnesium sulfate anhydrate and also after purification under fractional distillation. It was found that at least 13 compounds was detected contains of turpuntine oil sample from local producer and 10 compounds compose of sample from local market in Malang. α-Pinene as the main compound composes 64.63% from the first sample meanwhile sample from local market indicate in 55.75%. Moreover, fractional distillation under reduced pressure could provide α-pinene in 88.2% purity and 11.8% of δ-carene as the minor compound, respectively. Keywords: turpentine oil, α-pinene, GC-MS, essential oil

Abstract. Phytochemistry and biological activity investigation of medical plants was an important step in exploring of their potency. The objectives of this research were to determine the antioxidant activity of the extract and purified isolate of C. alata leave and also, to elucidate of the molecular structure of the responsible molecule. The methods used were extraction, isolation and purification by means of chromatography, DPPH radical scavenging and spectroscopy. Result of the research provided antioxidant activity was (ED5o) 28.50±1.86 µg/mL for the extract and 9.99±0.28 µM for the purified isolate. Elucidation toward the purified isolate indicated kaemferol structure as the most active antioxidant compound. (JKS 2007; 3: 125 - 130)

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.

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.
