Abstract

Coconut shells and waste cassava peels could be used as the main raw material for biomass briquettes for alternative energy sources in Indonesia. This study aims to analyze the quality of briquettes based on a coconut shell and cassava peel adhesive through proximate analysis with three treatment ratio variations. The ratio of coconut shell to cassava peel used varied from V1 (75%:25%), V2 (70%:30%), and V3 (65%:35%). Based on the result, the charcoal briquettes produced have a density of 0.61 gram/cm³-0.66 gram/cm³, water content of 5.51%-7.85%, ash content of 1.50%-2.86%, combustion rate of 0.021 gram/s-0.026 gram/s, and the calorific value of 6,161 cal/gram-6,266 cal/gram. However, all the treatment variations appropriate the SNI 01-6235-2000, the national standard of Indonesia for the quality of charcoal briquette, which includes the calorific value (>5,000 cal/gram), moisture content (<8%), and ash content (<8%). Briquettes with the best quality were generated by V1 with a density of 0.66 gram/cm³, water content of 5.51%, ash content of 1.50%, combustion rate of 0.026 gram/s, and calorific value of 6,266 cal/gram. Furthermore, briquette material from the coconut shell waste with natural cassava peel adhesive can be feasible as an alternative fuel.

Abstract

Noni (Morinda citrifolia L.) is one of the many herbs which known as an anticancer agent. Nanoencapsulated form of noni extracts could help the body absorption and able to inhibit the proliferation of cancer cells in vitro. This study was conducted to examine the anticancer activity of nanoencapsulated noni extracts in vivo as the anti-proliferation agent of cancer cells. Noni extract was obtained by maceration method using water as a solvent. The nanocapsule of noni extracts was made using the ionic gelation method by magnetic stirrer with the speed of 1500 rpm. In vivo anticancer activity test was conducted in Balb/c male mice by comparing the treatment of nanoencapsulation noni extracts and non-encapsulated extracts. The result showed that the nanoencapsulated noni extracts have a particle size of 27-59 nm. Percent of inhibition of nanocapsule on cancer cells (specifically on fibrosarcoma of Balb/c male mice) were equal to 54.75% (P2), while non-encapsulated is 49.72% (P1). Nanocapsule of noni extracts has anticancer activity better than non-encapsulated form on fibrosarcoma of Balb/c male mice. Keywords: anticancer, nanoencapsulation, noni extract

Abstract

Lumajang Regency, especially Bades Village, is one of the central managements of coastal and marine areas in East Java Province. One of the fishermen groups in Bades Village is the Mina Dampar Fishermen Group. Until now, these fishermen groups have not been able to utilize coastal areas for small-scale people's ponds due to limited knowledge of intensive shrimp farming technology, limited access to capital, and limited market information. This Technical Guidance aims to broaden horizons and introduce vannamei shrimp farming technology to fishermen who are members of the Mina Dampar group. This technical guidance activity was carried out at the Fish Landing Base in Bades Village and was targeted at the Mina Dampar Fishermen Group. The mentoring method used is the Participatory Rural Appraisal (PRA) method. This Technical Guidance aims to broaden horizons and introduce vannamei shrimp farming technology to 10 fishermen who are members of the Mina Dampar group. This technical guidance consists of outreach activities and field orientation. This activity shows that fishermen are interested in cultivating vannamei shrimp in Bades Village, especially freshwater vannamei shrimp cultivation. Cultivating freshwater vannamei shrimp can be a source of income for fishermen while doing housework.

Abstract

Cultivating vannamei shrimp has dominated fishery sectors and led to aquaculture development to enhance the Indonesian economy. Lumajang, specifically Bades Village, is one of the potential regions in Jawa Timur for improving fishery products because of its long shoreline of approximately 75km. Developing shrimp cultivation requires vast funds, intensive pond systems, and broad markets. Consequently, a large number of vannamei shrimp cultivation is controlled by a large company, which will supersede the role of traditional or local fishermen. This program utilizes two main methods: socializing about the opportunity of production, cultivation, and building a business entity of vannamei shrimp and practicing creating a small pond using geomembrane as a natural insulator. These activities intend to significantly increase the interest and enthusiasm of fishermen to develop vannamei small pond systems as a solution for economic independence and new income sources. As a result, a local fishing group, widely known as Mina Dampar as a partner, accepted and approved those programs implemented in their region in a 2000m2 land area.

Abstract

Direct extraction and conversion of microalgal lipid to biodiesel in one step process is developed to initiate an efficiently method in the biofuel production. The method that called as in-situ process had been applied in the biodiesel production from microalgae Chlorella vulgaris lipid by involving of sonication assisting. Various parameters that affect the in-situ transesterification were investigated to find the optimum conditions including power of sonication, co-solvent use, and biomass amount. The experiment was performed by acidic catalyst The use of sonication in 25kHz/270W yielded the highest biodiesel product. The apply of co-solvent n-hexane significantly increased the yield biodiesel rather than no co-solvent. The biodiesel yield of 10.39 % obtained when the process was accompanied by the n-hexane.as co-solvent with increasing level as 47% rather than without co-solvent. The in situ process in the ratio biomass - methanol 3:50 that assisted by sonication for 60 mins produced the highest biodiesel, which was 20,31 % w/w. The yield was higher than assisting with reflux or combination of reflux-sonication. The component of biodiesel yielded in the process consisting of 7,10,13-hexadecatrienoic methyl ester; pentadecanoic acid, 14-methyl-methyl ester; 9,12,15-octadecatrienoic acid-methyl ester; and eicosanoic acid-methyl ester. Joining of reflux-sonication exhibited a low biodiesel product. Disadvantage method from the combination may inhibit on lipid extraction or FAME transformation, the exact cause needs to be looked for in the future.

Abstract

The protein adsorption was interesting study, especially in the biological fluidic application. In the present study, we study the protein adsorption behavior on the bacterial cellulose and modified bacterial cellulose. In here, bacterial cellulose was modified by acid hydrolysis using hydrochloric acid. The contact time and pH were used as variable to study protein adsorption behavior on the modified bacterial cellulose. As the results, based on functional group analysis, there are not different between bacterial cellulose and modified bacterial cellulose. However, after modification, there was increasing of crystallinity of bacterial cellulose from 84.5% to be 87.7%. In the protein adsorption study, increasing the contact time increase percent adsorption until contact time of 90 minutes, however the further contact time relatively constant. The protein adsorption on both of bacterial cellulose and modified bacterial cellulose decreases, following the increase of pH.

Abstract

One of the factors that determine the formation of the membrane is the solution in the coagulation bath (non-solvent). In this study, the effect of pH treatment on the coagulation bath solution on membrane formation and its effect on membrane performance will be studied. The pH of the coagulation bath used was pH 1, 6.8 and 12. As the results, physically the three pH treatments produced the same white (opaque) membrane. Through morphological analysis, it appears that the three pH treatments produced an asymmetric membrane consisting of a top layer and a sublayer. The surface of the membrane with pH 1 treatment showed a denser surface than the pH 6.8 and pH 12 treatments. The results of the membrane performance characterization showed that the membrane permeability coefficient of the membrane with pH treatment was in the following order pH 1 < pH 12 < pH 6.8. While the value of the rejection coefficient showed that the membrane treated at pH 1 did not detect rejection because there was no permeate coming out, while at the treatment at pH 6.8 and 12, the rejection coefficient values were 74% and 76%, respectively.

Abstract

Blend polysulfone (PSF)/cellulose acetate (CA) membranes have prepared by phase inversion method. In here, CA was prepared from bacterial cellulose by acetylation reaction. Various temperature of coagulation bath were used as variable to investigated water uptake, water flux, porosity and thermal properties of membranes. As comparison, the CA commercial (CCA) was also investigated with the same parameters. As the result, the functional group analysis by FTIR show that CA has successfully prepared from bacterial cellulose. The parameters include water uptake, water flux and porosity have the similar trend. The parameters increase with increasing of temperature of coagulation bath. The other hand, CCA membrane have similar trend to CA membranes for parameter of water water uptake, water flux and porosity. However, CCA membrane is higher than CA membranes for all parameters. Thermal analysis by Differential Scanning (DSC) showed that all blend membranes with different temperature of coagulation bath have single transition glass temperature (Tg) that indicated that molecular homogeneity. Keywords: blend membrane, phase inversion, coagulation bath, water flux, porosity.
