Judul: Development of Business Model Manufacturing Company in PT Bando Indonesia, Development of Business Model Manufacturing Company in PT Bando Indonesia
Abstrak: PT Bando Indonesia is one of the best manufacturing companies in the automotive sector in providing power transmission belts in Indonesia. PT Bando Indonesia's products have been accepted in several countries. And these products are used by the automotive industry, conveyors, and other industries. However, this company still faces obstacles in its activities, and one of the problems is the fulfillment of production capacity. This research aimed to identify and evaluate the impact of business environment factors and current business models. The second purpose of this research to determine alternative business strategies that are possible to implemented by the company. The third purpose of this research to formulated recommendations new business model based on the studies that have been done. This research uses two types of data, primary data, and secondary data. The primer data comes from interviews, questionnaires, and the FGD of the company, and the secondary data comes from company profiles, literature, and internet. Primer data and secondary data will be processed and analyzed first using internal analysis (IFE) and external analysis (EFE) to know the company's business environment. The results from internal analysis (IFE) and external analysis (EFE) will be the basis for the alternative strategy with SWOT analysis. The final method is to build an alternative triple-layer business model canvas (TLBMC). The alternative business model has been influenced by an alternative strategy from the swot analysis that has been prepared previously. The results showed that the company was in good condition. The research output had indicated by the IFE analysis score of 3,06 and the EFE analysis score of 2,74. The SWOT analysis in this study showed several alternative strategies to support the company's business. Alternative strategies have the effect of building alternative business models based on TLBMC. Previously, the company's business model has been analyzed using the TLBMC approach, with economic, environmental, and social factors. The influence of the alternative strategies formed on the business model is the addition of several blocks in TLBMC. The company's problems in procuring raw materials solve by apply EOQ, safety stock, forming a new business unit and using substitute materials. The solution to labor problems in a company is raising the welfare and confidence of the existing workforce. The storages problems of the company faced by maximizing operational effectiveness based on the alternative business model

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
