Abstract - Research on the effect of the use of HCl concentrations in the hydrolysis process of cellulose from medang wood (Neolitsea latifolia) on the characteristics of microcrystalline cellulose has been studied. The purpose of this study was to determine the effect of HCl concentration on the characteristics of microcrystalline cellulose. The analysis carried out included yield, pH, color, functional group characterization using FTIR and crystallinity index using XRD. The hydrolysis process was carried out at 105 °C for 15 minutes with variations in HCl concentrations of 1.5 N, 2.5 N and 3.5 N. Based on the results of the research conducted, the results showed that the use of variations in the concentration of HCl in the hydrolysis process affected the yield, color, TCI (Total Crystallinity Index) value of FTIR data and crystallinity index of XRD data. The yield of microcrystalline cellulose produced from each variation of concentration was 64.41, 61.94 and 53.99. The color of microcrystalline cellulose is getting darker as the concentration of HCl is used. Based on FTIR data, the TCl value of microcrystalline cellulose from each variation of concentration was 0.861%, 0.907% and 0.976%. XRD data shows an increase in crystallinity index produced from each variation in concentration on microcrystalline cellulose amounted to 80.52%, 82.17% and 83.49%.

Abstrak. Alang-alang (Imperata cylindrica) mengandung sekitar 59% holoselulosa dan dapat digunakan sebagai bahan baku bioetanol. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pretreatment menggunakan asam encer terhadap karakteristik struktur kimia pada lignoselulosa alang-alang. Pretreatment dilakukan menggunakan asam encer dengan konsentrasi H2SO4 1%, 2%, 3% dan 4% pada suhu 210°C dalam autoclave selama 45 menit. Analisis perubahan struktur secara kimia setelah pretreatment dengan asam encer dilakukan menggunakan Spektroskopi Inframerah Transformasi Fourier (FTIR). Analisis perubahan warna dilakukan dengan metode CIELAB. Hasil yang diperoleh dari spektra FTIR mengindikasikan bahwa asam encer mendekontruksi strukur kimia dari alang-alang dengan melarutkan hemiselulosa selama proses pretreatment. Perubahan warna (ΔE) berkolerasi dengan modifikasi struktur kimia pada lignoselulosa alang-alang. Kata Abstrak.

Logam berat merupakan unsur yang seringkali menjadi polutan utama dalam pencemaran air dan dapat membahayakan kehidupan organisme. Penelitian ini bertujuan untuk memprediksi pola perpindahan ion logam Pb dan Zn dari badan air ke sedimen berdasarkan fenomena adsorpsi isoterm di waduk Riam Kanan Kecamatan Aranio Kabupaten Banjar. Selain itu , penelitian ini diharapkan dapat memberikan informasi terhadap rona awal waduk Riam Kanan, dinamika, dan keadaan ion logam Pb dan Zn di sepanjang waduk Riam Kanan dari hulu hingga hilir. Metode yang digunakan adalah Standar Nasional Indonesia (SNI) dengan menggunakan instrumen Spektrofotometer Serapan Atom (AAS). Hasil analisis laboratorium diperoleh rata-rata kandungan Pb di air sebesar 0,0494 ppm – 0,2582 ppm, Zn sebesar 0,0002 ppm – 0,0370 ppm, sedangkan sedimen Pb sebesar 6,8311 mg/kg – 21,1756 mg/kg dan Zn 3,3778 mg/kg – 28,3522 mg/kg. Berdasarkan data percobaan ternyata perpindahan ion logam Pb dan Zn ke sedimen akan mengikuti model adsorpsi Langmuir dengan koefisien determinasi (R2) sebesar 0,8167 dan 0,8801. Keywords: Model adsorpsi, logam berat (Pb dan Zn), air, sedimenHeavy metals are often considered as main contaminant in water pollution and its highly dangerous for living organisms in the contaminated area. The aim of this research is to predict the movement pattern of Pb and Zn metal ions from water onto sediment in the Riam Kanan Reservoir, Aranio Sub-district, Banjar District. In addition, this study is expected to give information on the initial condition of Riam Kanan reservoir; dynamics; and the fate of Pb and Zn ions from upstream to downstream. The samples were analysed using AAS (Atomic Absorption Spectrophotometer) based on the Indonesian National Standard (SNI). Result of laboratory analysis showed that in the water, contents of metal Pb were 0.0494 ppm – 0.2582 ppm, Zn 0.0002 ppm – 0.0370 ppm. In the sediment, contents of Pb were 0.8311 mg/kg – 21.1756 mg/kg and Zn 3.3778 mg/kg – 28.3522 mg/kg. Based on the experimental data, it was found that the displacement of Pb and Zn onto sediment complies with Langmuir adsorption model where the determination coefficient (R2) were 0.8167 and 0.8801 respectively. Keywords: Adsorption model, heavy metal (Pb and Zn), water, sediment

Synthesis of g-Al2O3 from Tatakan, South Kalimantan kaolin using simple methods: metakaolinization, dealumination, precipitation process using polyethylene glycol (PEG-6000) as a structure directing agent, calcination steps, and characterization of its products have been presented. The purified kaolin was metakaolinized and dealuminated to get amorphous aluminum hydroxide. After that, the sample was precipitated using the various concentration of PEG and NH4OH as the precipitating agent. Calcination process was carried out at calcined at a temperature of 700°C for 3 hours. Based on the FTIR spectra and X-ray diffraction of the g-Al2O3 obtained was similar to that of commercial g-Al2O3. The highest crystallinity of g-Al2O3 was formed when using twice of critical micelle concentration of PEG (10-3 mol/L). This simple process is an industrially practicable substitute to the Bayer process

In this research, the synthesis of nanocellulose from Nypa fruticans fronds as a filler of polyvinyl alcohol-based bioplastic has been carried out. Nanocellulose synthesis was carried out using sulfuric acid hydrolysis process with a concentration of 30% and the results were analyzed using a Particle Size Analyzer. The effect of addition of the amount of nanocellulose on bioplastics from polyvinyl alcohol such as moisture content, thickness, transparency, vapor transmission rate, solubility and functional group analysis using FTIR have been evaluated. The results showed that the nanocellulose from Nypa fruticans fronds had a diameter below 600 nm. The addition of nanocellulose with a concentration of 0.2%; 0.4% and 0.6% into the polyvinyl alcohol bioplastic can increase the thickness and transparency of the bioplastic, and reduce the water vapor transmission rate. However, the addition of nanocellulose in this range did not significantly affect the water content and the solubility of bioplastics in water.

Guntung Payung land condition majority is peat that makes low productivity of vegetables, difficult land preparation, and much consume of fertilizer. In the other hand, partner location in this program is an urban area that near international airport, caused the change in land function from the farming area to be residence area. That condition caused the traditional farming area is not enough. The low education level and skills of community inhibit to learn and try new technology for increasing income level. The training of the hydroponic system to the community in this program can solve the problem that happens in this partner community. With knowledge of hydroponic technology, it is expected that the partner’s income will increase and this group of hydroponic farmers can supply the vegetables need in Banjarbaru area.
