The tofu industry in Indonesia generally utilizes simple processing technologies, leading to unresolved wastewater management issues. Tofu wastewater contains high organic matter, measured by BOD, a parameter indicating the oxygen required by microorganisms to decompose organic matter. High BOD can decrease dissolved oxygen (DO) levels in water, which is crucial for aquatic life. This study investigates the effectiveness of local probiotics in reducing BOD and increasing DO in tofu wastewater (ABIT). Three treatments were applied: pure ABIT, neutralized ABIT (ABIT-N), and ABIT mixed with local probiotics in three ratios (1:1, 1:2, and 1:3). DO was tested at 0, 8, 16, 24, and 36 hours, while BOD was tested at 0 and 5 days. The results demonstrate that local probiotics can effectively reduce BOD and enhance DO levels in ABIT. The highest DO (3.36 mg/L) was observed in ABIT-N mixed with local probiotics at a 1:3 ratio after 32 hours. The most significant BOD reduction (135.77 mg/L) was also achieved at the 1:3 ratio. These findings suggest that local probiotics offer an eco-friendly approach to treating tofu wastewater.

In Indonesia, there are two types of motorcycle transmissions: manual and automatic. Users prefer automatic transmissions due to convenience and fuel efficiency. Automatic transmissions, such as CVT, CVT utilizes force for smooth and continuous gear ratio changes. CVT has disadvantages because unlike manual motors that have greater torque, especially on motorbikes that are three years old or more, such as poor acceleration at low to medium revolutions and wasteful fuel. This study aims to determine how the effect of adding spring plate and roller mass variations on torque and fuel consumption. This research uses a quantitative method with an experimental approach, by testing the independent variable to determine the results of the dependent variable. The result of this research is the use of lighter rollers can increase fuel consumption but the torque is getting smaller, because the use of lighter rollers has a fast rotation response so that the crankshaft in rotating the roller housing pulley is also lighter so it does not require a lot of fuel. While the use of heavier rollers coupled with spring plates also increases torque because the displacement ratio is faster, the torsional moment will be large which causes the torque to increase.
