Since Covid-19 arrived in Indonesia, all policies have been carried out to stop the spread of this virus, one of which is the PSBB. The impact of the PSBB is felt by the drastic increase in the number of unemployed in Indonesia. Using Multiple Classification Analysis (MCA), this research was conducted in order to see the condition of the Open Unemployment Rate (TPT) in each province in Indonesia between before and during the pandemic, and to find out the factors that influenced it. The results show that both before and after the pandemic, provinces with an HDI below the national figure led to higher TPT. The growth rate of GDRP and UMP has a different effect between before and during the pandemic. Other results also show that before the pandemic, UMP had the greatest influence on TPT. But after the pandemic, the one that had the biggest impact was HDI.

This study aims to investigate the average travel cost budget (TCB) distributions among household life stages (HLS) groups considering the bus users of Trans-Koetaradja in Banda Aceh, capital of Aceh province. This research was conducted within three corridors of Trans Koetaradja. The onboard survey is performed to collect bus users related information such as their monthly travel budget, socio-economic attributes, and travel/mobility characteristics. In this study, we only consider to analysis the distributions and characteristics obtained data sets by deeply investigating socio-demographics and travel attributes of bus users. The analysis result reveals that the group 3 (families with pre-school children) spent the highest average of TCB (0.442 million IDR/month) and group 1 (single person) spent the lowest TCB (0.280 million IDR/month). While group 2 (childless couple) has portion the lowest average of TCB about 10.2% from their monthly income, and group 3 (families with pre-school children) has shared the highest TCB accounting up to 14.4% from their monthly income compared to the remaining groups. This result depicts that an average TCB across HLS groups is considerably high, especially early household life stages development. It is may partially due to a limitation on their monthly income and lack of affordable transport mode for them.

ABC Factory is one of the companies engaged in manufacturing precast concrete in Indonesia. This company was established in 1978 under the auspices of XYZ Group Since. The products produced by ABC Factory are Precast Concrete / Prefabricated Concrete or often abbreviated as "PC". Some of the products manufactured by ABC Factory are PC. Spun Pile, PC. Square Pile, PC. Spun Pole (Electric Pole), PC. I Girder, PC. Box Girder and several other products. ABC Factory uses the Make to Order production method, so it is demanded to produce orders maximally and as efficiently as possible. In this manufacturing company, the preparation of the layout of production facilities greatly affects the production cycle time which in turn will have a major effect on the company's production capacity. for that, the company needs to redesign the layout of the PC production facility of Spun Pile with the best production flow. Based on these problems, the method used is to use the SLP (Systematic Layout Planning) method which functions to produce a layout design for production facilities that minimizes material movement distance and produces a good production flow in ABC Factory. Based on the results of the study obtained a reduction in the distance of material flow facility layout by 72.71 meters and an increase in production capacity of 138 cigarettes or 13.44% of the initial layout.

Srikaya leaf (Annona squamosa L.) is a plant that contains several active compounds including flavonoids, saponins, alkaloids and tannins which have antibacterial properties. Transparent antiseptic extract of srikaya leaf (Annona squamosa L.) has antibacterial activity against Staphylococcus aureus. This research method is an experimental study with physical and chemical evaluation of the preparation as well as testing of antibacterial activity using the paper disc technique diffusion method at concentrations of 1%, 2%, 3%, negative control and positive control. The results of the study at concentrations of 1%, 2% and 3% met the physical and chemical requirements as well as the antibacterial activity test with a concentration of 1% inhibition zone 15.6 mm (Strong), 2% inhibition zone 19.6 mm (Strong) and 3% zone of inhibition 21.2 mm (Very strong). It was concluded that for a concentration of 3% with an inhibition zone diameter of 21.2 mm (Very strong) the most effective.
