Analyzing the Cr(III) adsorption properties of bagasse lignin (LB), bagasse lignin carbon (LBF), and lignin amine (LA). Variable adsorption studies were performed, including variations in mass, contact time, and pH. The adsorption ability test was carried out first by varying the mass of the adsorbent to determine the optimum mass of each adsorbent LB, LBF, and LA for the Cr(III) adsorbate. The ability of lignin adsorbents (LB, LBF, and LA) to adsorb Cr(III) was optimum at 0.015 g adsorbent mass contact time of 90 minutes, and the adsorbate solution had a pH of 6. The adsorption capacity (Qm) value for bagasse lignin adsorbent (LB) was 8.6050 mg/g at 30°C, bagasse carbon lignin (LBF) was 9.8717 mg/g (30°C), and ammine lignin (LA) with the highest value is 9.9800 mg/g (35 °C).

Penelitian ini dilakukan untuk menganalisis konsentrasi PM2.5, CO dan CO2 dalam ruangan ketika dilakukan penggunaan bahan bakar biopelet pada sebuah kompor biomassa, serta menghitung laju konsumsi bahan bakar tesebut. Pengujian menggunakan metode water boiling test (WBT) untuk mensimulasikan proses memasak yang terbagi ke dalam 3 fase, yaitu cold start (CS)/fase dingin, hot start (HS)/fase panas, dan simmering (SM)/fase mendidih. Biopelet dibuat dari limbah sekam dan jerami padi. Pengukuran PM2,5 dilakukan menggunakan low volume air sampler (LVS) yang dilengkapi dengan elutriator untuk memisahkan partikel berukuran di atas 2,5 mikron dan filter fiberglass untuk menangkap partikel berukuran kurang dari 2,5 mikron pada kecepatan aliran udara 3,5 liter per menit. Sedangkan pengukuran CO dan CO2 menggunakan Portable Air Quality Monitor. Didapatkan konsentrasi PM2,5 biopelet sekam padi pada fase CS, HS, dan SM berturut-turut 33,13,30,81, dan 24,76 μg/Nm3, sedangkan untuk biopelet jerami padi diperoleh 23,29, 29,98, dan 30,42 μg/Nm3.Terkait konsentrasi CO, pada ketiga fase berturut-turut untuk biopelet sekam padi yaitu 5,29, 5,14, dan 6,09 ppm, sedangkan untuk biopelet jerami padi didapatkan 6,13, 5,86, dan 5,67 ppm. Terakhir, pengukuran konsentrasi CO2 biopelet sekam padi yaitu 436,74, 451,71, dan 472,82 ppm, sedangkan pada biopelet jerami padi terukur 419,87, 417,93, dan 453,43 ppm, pada ketiga fase berturut-turut. Konsentrasi PM2,5, gas CO dan CO2 biopelet masih memenuhi baku mutu udara indoor sesuai dengan PERMENKES/1077/2011. Rasio CO/CO2 berada di bawah nilai 0,02 yang menunjukkan pembakaran bahan bakar biopelet menghasilkan karbon monoksida yang kecil sehingga terjadi pembakaran sempurna. Laju konsumsi bahan bakar biopelet lebih kecil dibandingkan jika digunakan biomassa yang belum diolah menjadi biopelet. ABSTRACTThis research was conducted to analyse indoor PM2.5, CO dan CO2 concentrations during the use of biopellet fuel in a biomass stove, and to calculate the fuel consumption rate. Water boiling test (WBT) was used to simulate cooking activities, which comprises of three phases, i.e., cold start (CS), hot start (HS), and simmering (SM). The biopellet was made from rice husk and straw wastes. PM2.5 were measured by using a low volume air sampler (LVAS) that was equipped with an elutriator to separate particulates with more than 2.5-micron size and a fiberglass filter to trap particulates with less than 2.5-micron size at air flow rate of 3.5 liter per minute. Meanwhile, a portable air quality monitor was used to measure CO dan CO2. It was found that PM2.5 concentrations for rice husk biopellet during CS, HS, and SM were, respectively, 33.13,30.81, and 24.76 μg/Nm3. While those for rice straw biopellet were 23.29, 29.98, and 30.42 μg/Nm3. Regarding CO concentrations during the three phases for rice husk biopellet were, respectively, 5.29, 5.14, and 6.09 ppm, whilst for the rice straw biopellet the concentrations were 6.13, 5.86, and 5.67 ppm. Lastly, the CO2 measurements for rice husk biopellet were 436.74, 451.71, and 472.82 ppm, while those for rice husk biopellet were 419.87, 417.93, and 453.43 ppm, during the three phases correspondingly. All PM2.5, CO and CO2 gas concentrations still met indoor air quality standard, in accordance with Minister of Health Regulation Number 1077/2011. Moreover, the CO/CO2 ratios were below 0.02, which indicates that the combustion of the biopellet fuels emited small amount of carbon monoxide, thus, perfect combustion were achieved. The biopellet fuel consumption rates were smaller than those of virgin biomasses that had not been converted into biopellet

“…The lignin content in biomass pellet making material can be one of the determinants of the heating value produced because it can influence the density of biomass pellets during the densification process [35]. This is reinforced by [36] that the lignin content in lignocellulosic plants can be used as an adhesive with certain processes both physically and chemically. Cacao raw materials produce 21.29-51.98% lignin [16] [19].…”

Biomass is a suitable material to be developed as an alternative energy source to substitute fossil fuels. Waste of Cacao and banana processing (peel) are potentially forming into biomass pellets because they have high calorific value. Increasing the caloric value of biomass fuel can be done through the densification process to produce biomass pellets. This study aims to find the best-mixed formula and particle size (mesh), thus calculate the physical properties of the best biomass pellets. The quality of biomass pellets is determined by the physical properties of the pellets. Processing of biomass pellets is by drying cocoa skin and banana peel, grind with a hammer mill, and sieved with a size of 20, 40, and 60 mesh. Materials are mixed with composition of cacao pod husk and banana pod husk are 80% : 20%, 70% : 30%, 60% : 40%. Biomass is pressed using a hydraulic press with a diameter of 1 cm, and a height of 1 cm then dried to reduce the moisture content. The result shows the best formula of biomass pellets occurs in a combination of 80% cacao pod husk and 20% banana pod husk with 60 mesh. This biomass pellet has physical characteristics for calorific value of 4049,815 cal/g, a volatile matter value of 78,92%, moisture content of 5.17%, ash content of 9,8%, and density of 5,214 gr/cm 3. Banana pod husk with high levels of lignin can be used as an adhesive, it binding cacao pod husk particles properly and increase density and calorific value.
