As one of dam priority in Indonesia, Cipanundaan dam faced severe problem related to the sedimentation. The sedimentation in Cipanundaan derived from both soil erosion and landslide (earth slide and earth flow) along the river. Based on analysis, total potential sediment reached until 137,819 m3, which is shortened the dam lifespan only for 10 years. This research is conducted the effectivity of application of underwater dam in order to maintain intake system. Three underwater dams are constructed for controlling 8 mm/year of sedimentation from both erosion and translational landslide. The numerical modelling used ANSEDIM program to develop surface sediment elevation in reservoir. The result showed the infrastructure is succesfully suspending sediment enter the system, thus, the dam has a longer lifetime. The research revealed that application of three underwater dams will reduce 2.5 times of sediment volume, increase up to 6 times of effective volume and extend the dam’s lifetime until 250% from existing condition. This outcome will be helpful to planner, engineers and managers for better managing of reservoir sedimentation and water resources.

Published: August 2021

Economic movements in Indonesia and the logistics and distribution systems that accompany them are highly dependent on road transportation modes. On the other hand, the islands of Sumatra and Java are the centers of concentration for the Indonesian economy where the number of people inhabiting the two islands reaches 80% of the total population of Indonesia. In order to accelerate development and increase the economic integration of Java and Sumatra, it is necessary to build the Sunda Strait Bridge. The main bridge considered incudes the long span suspension bridge. At present, the planning and construction of the long bridge including suspension bridge was greatly affected by the failure of the Taccoma Narrow Bridge on 7 November 1944. Due to the wind load, the bridge structure shook until it finally collapsed. Although the cause of the collapse was not immediately known, it is currently concluded that it was caused by a single degree of freedom torsional flutter caused by self-excited wind load. This phenomenon is classified as an aerodynamic phenomenon on long span bridges. The flutter analysis performed on the Sunda Strait Suspension Bridge using the Direct Flutter Analysis method will be presented in this paper.

Nowadays, the citizen of the main city in Indonesia relies on app-based transportation to fulfill these needs, especially the motorbike taxi services. Many factors affect the convenience and safety of the passenger, especially a driver’s driving behavior. This research aims to measure a motorbike taxi driver driving behavior level using a Manchester Driving Behavior Questionnaire (MDBQ). Furthermore, the correlation between emotional intelligence (X1), the need for self-recovery (X2), and work motivation (X3) variables with driving behavior (Y) was measured. Using a set of questionnaires, the 200 app-based motorbike taxi drivers’ opinions on those variables were collected. The participants were drivers who operate in the Indonesian capital city and its four adjacent cities. To see the correlation of the variables, a Binary logistic regression method was applied. One way ANOVA was also utilized to find out whether the age, driver’s income, and driving duration differentiate the level of Y, X1, X2, and X3. The result showed that X1 had a negative influence on the Y, while X2 and X3 had a positive influence. The correlation can be explained by the equation Y=- 7,491 + 0,067X1 + 1,388X2 + 0,577X3
. One way ANOVA results showed that the emotional intelligence level statistically different among the age class (p = 0.095), the work motivation level statistically different among drivers with different driving duration per day (p= 0.035). This research provides a new perspective that driving behavior is influenced by those variables. The implication, to manage or to correct the driving behavior of drivers, the app-based transportation company service could set some regulations related to this matter. The company may consider limiting the driving duration and give rewards to the drivers who able to manage their driving duration and their driving behavior.

A non-thermal plasma system has been utilized as a new alternative sterilization method for food products. Non-thermal plasma generates free radicals, reactive oxygen species (ROS), and reactive nitrogen species (RNS) that contribute to bacterial cells inactivation. This review focused on the factors that affect the non-thermal plasma efficacy to microbial inactivation during the development of milk cold sterilization. The plasma effectiveness in inactivating bacteria could be affected by the attributes of plasma treatment time, the applied voltage, working gas and the type of plasma system. The non-thermal plasma system successfully applied to reduce the number of total bacteria in milk and prolong the shelf-life.
