Abstract. Compression molding is a major technology in the plastic industry, and the one of the original
processing technique for manufacturing plastic. The current study was aimed to design and fabrication
of mini compression molding machine for use in laboratory workshop or education institution. This
machine was designed and fabricated to reduce the cost of expensive purchasing and cost maintenance
of compression molding machines used in the industry. Mini compression molding provides for study of
implemented to facilitate the production process of plastic products according to the mold provided. This
machine used an oven as a heater to melt the resin in the mold provided and car jack as pressure to
compress the resin after melting. The parameter has been considered is a temperature and pressure of
the process of flow raw material into the cavity and period of time of melting. Based on the test, the
optimize of temperature suitable for heating the polypropylene plastic (PP) to melt is at 250°C, while the
best time to melt of at 250°C is within 15 minutes. From the results obtained based on the quality of
mold produced by the mini compression molding machine, the fabricated machine performance was
satisfactory and can be used locally institution and industrially in small scale. This Mini compression
molding used in Manufacturing lab in PSMZA for subject of DJF2012 (Manufacturing Workshop Practice
2) as development aids in Teaching and Learning.

Keywords: Compression molding, plastic product, parameter, teaching and learning, institution.

Abstract. Tobacco is cultivated for their by-product. In this research, by using tobacco as a basic
ingredient for botanical insecticide making, it had been tested on termites (Coptotermes formosanus)
population. Simple extraction from tobacco leaves containing nicotine as active ingredients were mixed
with garlic, salt, stone paste and fermented for 3 days. The application based on different dilution series
which are T1 (distilled water/control), T2 (pure stock), T3 (5 ml pure stock: 10 ml distilled water), T4 ratio
(1: 2) T5 (1: 3), T6 ratio (1: 4) and T7 with ratio (1: 5). 1.5ml of dilution being put on filter paper inside
petri dish which consists of 30 live termites. Each treatment consists of 3 replication. Data collections of
percentage dead termites are recorded for 1, 3 and 5 minutes interval. All collected data had been
analyses using Two-way ANOVA using SPSS version 24. The percentage of died termites recorded at
96.67% in treatment 2 and shown significant difference. Other treatments that show significant
differences are treatment 3 and 4. The best treatment was treatment 2 with highest percentage of dead
termites and shortest time intake. These botanical insecticide are effective in controlling termites
population thus it can be commercialized and safe to our environment.
