PENINGKATAN PERFORMA KEMASAN DAN STRATEGI PEMASARAN(IbM UKM Pengerajin Kerupuk Getas)

Kerupuk getas and kemplang are snacks from Bangka Island made from a mixture of mackerel and corn starch. The snacks are produced by snack food home industry.  The production center located in Belinyu and Pangkalpinang City. The main problem of industry is lack of knowledge about the packaging technology and sales strategy. The product packaging is an important part of a sales strategy. In this report, the authors proved statistically that the product packaging can increase revenue. The packaging system by using vacuum packaging machine. Furthermore, sales strategy be developed into an online system.The results show that sales of products with packaging boxes significantly affect gross income partners. Correlation test showed that the value of pearson product moment (r) is 0.862. The value of the Pearson product moment means that there is a very close relationship between the product packaging boxes with gross revenue and P-value is 0.05 so it was concluded that the relationship is significant. Keywords: product packaging, sales strategy, online system, pearson product moment, P-value

Carbon electrode sensitivity enhancement for lead detection using polypyrrole, ionic liquid, and nafion composite

This paper concerns enhancing a lead detection sensor using a combination of polypyrrole (PPy), Nafion (N), and ionic liquid (IL) with thick-film or screen-printing technology on sensitive material-based carbon electrodes. Electrode characterization using a scanning electron microscope (SEM) was conducted to see the morphology of sensitive materials, showing that the spherical particles were distributed evenly on the electrode surface. Analysis using energy dispersive spectroscopy (EDS) shows that the element's atomic composition is 84.92 %, 8.81 %, 6.26 %, and 0.01 % for carbon, nitrogen, oxygen, and bismuth, respectively. Potentiostat measurement with the ambient temperature of 25 °C on a standard lead solution with concentration ranging from 0.05 to 0.5 mg/l yields an average output voltage ranging from 2.16 to 2.27 V. It can be concluded that the sensor is able to detect lead with a sensitivity of 0.21 V in each addition of solution concentration (mg/l) and give an 84 % concentration contribution to the voltage
