Abstract

This research aims to find out the effect of logic concept mastery by cognitive development on physics science learning achievement with a problem-solving approach. The population of subjects was students of class VIII SMP Negeri 16 Palu with purposive sampling technique with a quasi-experimental method based on the results of data analysis can be concluded as follows: 1) oriented learning with a problem-solving approach to learning in the subject matter in class VIII of SMP can light improve student learning outcomes;  2) there was a significant effect between mastery of the concept of cognitive development to the learning outcomes with the value of R= 0.802; 3) the response of the student to the teaching component that includes teaching materials, LKS, practice, and approaches used by the teacher in teaching was happy and interested.

Abstract

The implementation of Modern EcoHeat Technology Innovation is designed to overcome the challenges of the non-standardised sea cucumber drying process. This programme is conducted in several stages, namely: Installation of EcoHeat drying technology in the production facilities of partner SMEs, training on the use of technology for employees and students, development of quality SOPs, and improvement of logistics management for more efficient distribution. This activity also includes regular evaluation of production processes and results to ensure improved product quality according to international standards. In addition, a social media campaign was implemented to support product marketing and increase consumer awareness about the benefits and quality of dried sea cucumbers from Bintang Laut SMEs. The results of the programme showed significant improvements in the efficiency of the production process, which enabled Bintang Laut SME Partners to increase production capacity and reduce operational costs. Improved product quality of dried sea cucumbers with more consistency and longer shelf life was also achieved, resulting in a positive response from the market. The programme also successfully enhanced employee skills through technology training and quality SOPs. The programme successfully optimised the production process with the support of modern technology and better implementation of quality SOPs. The programme was able to improve the competitiveness of dried sea cucumber products in the export market and provide opportunities for SMEs to maintain quality and expand markets

Abstract

Chips are a type of snack or snack made from tubers such as cassava and bananas which are usually produced by home businesses. However, most home-based chips making businesses still use manual tools such as kitchen knives or cutters so that production takes longer, the thickness cannot be adjusted and the risk of workers' hands being injured by knives is added. This cassava and banana chopper uses a driving motor system that is driven by an electric motor with a speed of 1400 RPM HP and the pusher is driven by a power window. The results of this tool chopping obtained thickness in cassava and banana is 1-1.5 mm which is the standard thickness of chips in general. In addition, the results obtained are faster production compared to manual techniques using a kitchen knife or cutter. The conclusion is that the cassava and banana chopper with a driving motor is very efficient for chip craftsme, because the production time is faster and the thickness of the cassava and banana slices is uniform, namely 1-1.5 mm.

Abstract

The making of this shallot peeling machine is intended for farmers and catering entrepreneurs to facilitate the process of peeling shallots. The research and design of this machine were conducted at the Poluteknik campus and Sirarata workshop, Sibowi Village, Tanambulava District. Sigi Regency, Central Sulawesi Province. This shallot peeling machine is very simple, using an electric motor with a speed of 1400 rpm as a driving force. This peeler rubber serves to peel the shallot skin. The result of this research is the creation of an shallot peeling machine with a frame length of 75 cm, a width of 40 cm, and a height of 88 cm so that the peeling results can help shallot farmers.
