Bacillus megaterium is a bacteria that causes human infections, causing keratitis, skin infections, brain abscesses and tissue infections. Treatment often uses chemical antibiotics. However, long-term antibiotics can cause new health problems such as resistance. Therefore, antibacterial ingredients are needed that can not only inhibit the growth of bacteria but also do not have a negative impact on health such as honey. Honey is thick, it can cure various diseases such as gastrointestinal, stomach, skin diseases, acute respiratory infections and coughs. This research aims to determine the ability of Sumbawa white honey as an antibacterial against B. megaterium. The method used in this research is paper disc diffusion. There were five treatments used in this study, between 100%, 75% and 25% honey concentrations, DMSO negative control and chloramphenicol positive control with five replications each. The results of the antibacterial activity test showed that the 100% concentration had an inhibitory zone diameter of 2.59 mm, then the 75% concentration was 1.46 while the 25% concentration was 0 mm. When compared with positive control, white honey was lower antibacterial. If it is in the white honey category, the inhibition zone category is included in the lower category.
巨芽孢杆菌是一种引起人类感染的细菌，可引起角膜炎、皮肤感染、脑脓肿和组织感染。治疗通常使用化学抗生素。然而，长期使用抗生素会导致新的健康问题，如耐药性。因此，需要既能抑制细菌生长又不会对健康产生负面影响的抗菌成分，如蜂蜜。蜂蜜浓稠，可治疗胃肠道、胃部、皮肤病、急性呼吸道感染、咳嗽等多种疾病。本研究旨在确定松巴哇白蜂蜜对巨型芽孢杆菌的抑菌能力。本研究采用纸片扩散法。试验采用100%、75%和25%蜂蜜浓度、DMSO阴性对照和氯霉素阳性对照5个处理，每个处理5个重复。抑菌活性试验结果表明，100%浓度的抑菌带直径为2.59 mm, 75%浓度为1.46 mm, 25%浓度为0 mm。与阳性对照相比，白蜂蜜的抗菌作用较低。如果属于白蜂蜜类，则抑制带类包含在较低的类别中。

Porang (Amorphophallus onchophyllus) has many benefits for industry and health, because of the high content of glucomannan in its tubers. Porang needs to be developed, but the problem is getting a uniform source of tuber seeds. To get the uniform tuber seeds by dividing them. This study aims to get a uniform source of tuber seeds. This study was conducted in the field and laboratory. The experiment was arranged in a CRD. There are two factors, in seed tuber division: U1= Intact tuber, U2=Tuber cut in 2, U3=Tuber cut in 3 parts, and U4=Tubers cut into 4 parts. The second factor is fertilizer consisting of Urea, Za, and Phonska. The results of the combined treatment between tuber division and fertilizer treatment showed no significant interaction in all observed parameters. The seed tuber division treatment affects the bud break time, plant height, stem diameter, and canopy width, only at the beginning of growth. U1 gives the highest growth. The various fertilizer treatments only had a significant effect on plant height and stem diameter at 7 and 8 WAP. The treatment of splitting tuber seeds can replace intact tubers to be used as Porang tuber seeds

Multivariable processes are the general classification for process features in the chemical industry. The variables in a single process unit interact with one another through more than one input and output. Since parameters interact with one another, changing one parameter's variable requires changing another parameter's variable as well. Further research is needed to determine how to create controllers that can handle interactions in the process. A MIMO control system is exemplified by the coupled tank system. Coupled tanks are present, and they communicate with one another by horizontal pipes. An interacting system can be represented using a coupled tank setup. Decoupling can be added to reduce the interactions that take place between variables. According to the results of the simulation, adding decoupling reduces the IAE value compared to not adding it. When the setpoint for tank level 1 (H1) was changed, the system's IAE value was 17.35 without the addition of decoupling, whereas it was 11.71 with it.
