Get PDFResidents of Bumi Salam Sejahtera 2 (BSS 2) Moncongloe Bulu Village, use their empty land to plant cassava. Currently, residents process cassava into fried cassava, cassava chips and other cassava preparations. Food process produces waste in the form of cassava peel cause a bad smell, build up rubbish and pollute the environment. Meanwhile, the need for sugar in Indonesia continues to increase every year, which results in sugar imports, so that alternative non-cane sweeteners are needed as raw materials for making sugar. Cassava skin has a high carbohydrate content so can be processed into raw materials for glucose production. Glucose is a material containing polysaccharides obtained from starch. The starch can be broken down by the amylase enzyme into sugar. The Community Partnership Program (PKM) aims to increase the selling value of cassava peel, as solution to overcome environmental pollution, and increase residents' income. The target achieved is the formation of economically independent community groups through entrepreneurial activities that utilize cassava peels into liquid sugar that is ready to be sold or consumed daily. The output target of this PKM is scientific articles published nationally, so that they can provide benefits to the wider community. This activity is carried out Socialization, Demonstration and Training.

PENERAPAN MACHINE LEARNING UNTUK MEMANTAU KERUSAKAN KONTAINER PADA GATE TERMINAL PETIKEMAS MAKASSAR NEW PORT
Get PDFThis research was conducted to design and develop a system capable of automatically monitoring and determining roof damage on containers before they enter the container yard. The monitoring is carried out at the gate area by applying a Machine Learning method, namely You Only Look Once (YOLO). Three types of damage are being monitored: rust, holes, and dents. Human error, extreme weather conditions, or collisions with other objects usually cause this damage. The results of the study show that YOLO in monitoring and identifying container damage achieved an 88.8% detection accuracy in the morning with a detection process duration of 31.5 seconds, a 90.9% detection accuracy during the day with a detection process duration of 31.1 seconds, an 87.7% detection accuracy in the afternoon with a detection process duration of 32.6 seconds, and an 83.6% detection accuracy at night with a detection process duration of 33.2 seconds. The low detection accuracy at night, which is only 83.6% is caused by less than optimal lighting, in contrast to daytime lighting. The real- time monitoring system functions quite well, as it can provide documentation evidence and continuously notify the gate inspector regarding the physical condition of the container roof.
