Rapid globalization has led to the growth of a significant amount of waste, including in the industry. Due to the considerable amount of growth of waste every year, effective and efficient waste management is needed to protect our environment. In the leather product industry, waste management is strongly important since it may have a significant impact to the employee and production process. Regarding those issues, waste management technology is considered proposed in order to solve those problems. Current research reported the outstanding work of implementing artificial intelligence for detecting and recognizing industrial waste. Artificial intelligence was proven to be a highly recommended approach that is able to classify several waste types with outstanding performance. Regardless of those facts, artificial intelligence still remains several hurdles, such as the high computational demands, especially for deep learning networks. Regarding the mentioned issue, we proposed a more proper deep learning network for recognizing industrial waste. In this research work, we use Single Shot Detector (SSD) to recognize and classify industrial waste. Our proposed solution was performed in the TrashNet dataset and Waste Picture dataset. Our proposed solution successfully achieve mAP of 0.8813, accuracy of 0,9795, precision of 0,9985 and recall of 0,9693 in the training process. Whereas, in the testing process we achieve average accuracy of 0,8254. According to those results, we can conclude that our proposed solution is suitable for industrial waste detection and has potential to be implemented as an embedded system for recognizing industrial waste automatically.

One of the small industries that survives and needs to be developed is the shadow puppet industry. The shadow puppet industry uses parchment skin as the main raw material. As a laboratory institution, the author tested the quality of parchment skin dye paint for shadow puppet using a crockmeter machine. The test is carried out by adding an auxiliary material in the form of ethylene glycol to the dye paint which is expected to improve the quality of the rubbing resistance of the dye paint on the shadow puppets. In this test the author uses parchment skin from sun-dried buffalo skin with a transparent color and an even thickness of the skin and a large cross-sectional area so that no part is wasted. Furthermore, the parchment skin surface was sanded before staining. This sanding aims to level the parchment skin surface and remove the remaining collagen, protein and fat. The test was carried out using 3 samples. Sample I used coloring materials (mowilex paint, foxputih glue, water and finishing using mowilex clear). Sample II uses coloring materials (mowilex paint, white fox glue, water, Ethylen Glycol and finishing using mowilex clear). Sample III uses dyes (mowilex paint, white fox glue, water, Ethylen Glycol, finishing using mowilex clear and the addition of a clearing process using a sunlight wetting agent. From the experiments and tests carried out, better results were obtained for the use of Ethylen Glycol in the coloring and also the clearing process to improve the color quality of the wayang kulit products produced.
