The use of the right method for inventory control problems is Just In Time , which is a management strategy used to optimize the production process and product delivery by buying and producing only when needed and at the right time. Silver Meal Heuristic, a heuristic approach used in inventory control to determine the optimal lot size. The quantity of raw material orders using JIT is relatively more than the silver meal, but with JIT the supplier only needs to send 4-5 times, meaning that the company can save costs. The quantity and frequency obtained from data processing using silver meal is more optimal. However, the cost of raw material inventory incurred is quite large. For a decrease in efficiency costs by implementing a policy of making purchases with Just In Time  (JIT) and is expected to save on raw material inventory costs. So that these cost savings can be allocated by the company to other costs.

Sambas has a traditional craft of songket cloth known as Kain lunggi or kain Bannang ammas because the motif is woven from gold and silver colored threads. Lunggi fabric has many weaving motifs, one of the most famous weaving motifs is the motif of bamboo shoots (Pucuk Rebung). But not a few people who do not know other motifs besides woven fabrics and other information about the motif of Sambas woven fabrics that are already quite global. So it is important to convey this information to the public interestingly. One of the media that can be used is through 3D animated films. This study was conducted by applying the MDLC method in which the process of modeling, rigging texturing, editing and animating in it. Based on the test results of 2 media experts at 84%, 2 material experts at 89%, and 30 general public at 89.46%, this animated film deserves to be published with a duration of 15 minutes and mp4 format.

The synthesis of PbO-Ag nanoparticles was carried out using the sol-gel method using bioreduction from fig leaf extract (Ficus Carica L). PbO is a semi-conducting metal, so it is combined with Ag metal to make PbO a conducting metal. The reason Ag is used is because the stability of silver nanoparticles plays a very important role when being characterized and applied to a product. The nanoparticles formed were characterized by PSA, PZC, XRD, FTIR, UV-Vis, DRS and SEM. From the characteristic results, it was obtained that PbO-Ag could be formed using the sol-gel method using fig leaf bioreductor (Ficus Carica L).
