Comparative study of Infrastructure Asset Management (IAM) between Papah irrigation areas in Indonesia and Cu-Chi irrigation areas in Vietnam
Authors: Cahyono C , Juliastuti  
Published: August 2021

Abstract
Infrastructure Asset Management (IAM) is implemented to overcome problems in the management of the agricultural sector. For example, in this study, the 2 research areas had similar problems, namely the poor water supply system in which the amount of water supplied did not match the initial design. To overcome this problem, IAM implementation in these two areas focuses on Integrated Water Resource Management. The objective of this implementation is that the ratio between the amount of water distributed and the one designed is close to 1 or the same. Based on the research results shown after implementing this IAM this problem was resolved. However, Cu-Chi Irrigation Area is still experiencing problems in the financial sector because the income from the sale of water supply is still far from the initial supply price. Whereas in Papah Irrigation Area this financial problem can be resolved with the implementation of the Irrigation Service Fee (ISF) and better management of the management company. Seeing this result, this ISF system can be applied to DI Cu-Chi to overcome the imbalance problem between the costs incurred for water supply and the revenue from the sale of the water.

Authors: Cahyono C , Juliastuti  
Published: August 2021

Abstract
Flood disaster management requires analysis and modeling, especially for the decision making of flood events. One way to analyze flood events is to use HEC-HMS software. HEC-HMS has three submodels: Loss, Transform, and Baseflow. In the flood discharge analysis, the selection of this sub-model is important because it is not certain that the method offered in this sub-model is suitable for all conditions, so it is necessary to choose which one is more suitable. Based on the results of the research, the SCS method can model well as evidenced by the good objective function values (RMSE (0.70 m; 49.05 m3 / s), Correl (0.931; 0.992), and DELTA PEAK (16.88%; 13.75%). The verification results are also show similar results (RMSE (0.63 m; 66,198 m3 / s), Correl (0.977; 0.916) and DELTAPEAK (43.04%; 32,754%). Therefore, it can conclude that the combination of benchmarking techniques that can be used for HEC-HMS modeling is the SCS curve number for losssubmodel, SCS unit hydrograph for transform submodel, and Recession constant for baseflowsubmodel.

Published: August 2021

Abstract
Flows that occur in rivers are usually accompanied by scouring/erosion and sedimentation/deposition processes. The scouring process that occurs can be caused by river morphological conditions and the existence of river structures that obstruct the flow. Structures such as bridge piers can change flow patterns so that in general can cause local scouring. One method for reducing the scouring that occurs around a bridge pier is to consider the shape of the pier bridge design. One of the most common pier bridge designs is the oblong shape. This research aims to find out the effect of streamlining the oblong pier shape on the change in flow characteristic and scour depth reduction using FLOW-3D numerical modeling.

Abstract

The road condition should provide a decent level of comfort, safety and efficiency for the road users. One of the pavement performance parameters that can be determined objectively is the International Roughness Index (IRI). This research uses a relatively new technology to measure IRI value named the Roadroid, which is an android application developed from a Sweden company. Roadroid uses a built-in vibration sensor on a smart phone which is placed on the vehicle and produces output value in the form of IRI and speed values. Roadroid application obtained output data based IRI value and speed value with high accurately because used real-time data with each vehicle type which get through each road surface condition. Each type of vehicle produces an output of IRI values on different roadroid applications for each type of road surface damage which is influenced by various factors, one of which is the vibration sensitivity setting factor of the roadroid application system during the start calibration of the type of vehicle selection. The IRI and speed value based on the output of the roadroid application have a high correlation of 87.8% on medium car.

Abstract
One effort that is considered very effective by the company is by building and increasing Health Safety Environment(HSE) awareness for all oil and gas workers. The efforts made by companies to develop and increase HSE awareness are by providing HSE compulsory training. This study aims to study how much influence HSE training has on the prevention of the main risks of well service activities in the oil and gas industry. Data was taken from the questionnaire given to 100 respondents in the weld services. Data wasanalyzed using SEM AMOS (Analysis of Moment Structures) method. The internal data of the company has recorded a significant increase in the number of occurrences of workplace accidents caused by a lack of HSE awareness. The study has compiled a matrix of HSE compulsory training that should be provided to all employees to increase HSE awareness to avoid the risks of major risk well services such as explosions, explosions of Fire and Gas and oil spills. The results of the company’s internal analysis show that the lack of HSE training for new employees and old employees as refreshment was one of the root causes of lack of HSE awareness in the work environment. As a result, the provision of HSE training significantlyimproves to prevent the main risks of weld service activities.

Published: August 2021

Abstract
The current progress of information and communication technology has been critical to the development of the Internet of Things (IoT) in a aquaculture system. IoT solution in this system utilizes interconnectivity between devices to obtain fish pond monitoring data from sensing devices and then transmit the data to a remote server to be analyzed for decision-making in pond management. In this paper, we propose a smart pond IoT solution that provides a continuous and real-time pond monitoring. The system principally embeds five sensors that measure critical environmental parameters to determine water quality: temperature, pH, dissolved oxygen (DO), total dissolved solids (TDS), and salinity. The IoT solution also integrates the development of a mobile application on the android platform that allows remote monitoring capabilities for users to maintain efficient pond management. The application is designed with a friendly-user interface that helps the farmer to monitor sensor measurements, manage fish production cycle, record fish feeding schedule, and also monitor the health status of fish from multiple ponds.

Published: August 2021

Abstract
Aquascaping is a branch of art by arranging and creating a closed environment in an aquarium ecosystem. Aquascape uses living plants as the main element with fishes, shrimps, snails as the additional element. Plants need light to carry out photosynthesis. However, the light needed has certain parameters and quantities for each type of plants. If the light used is less than the needs of the plants, the plants will not grow up properly, however if the light given exceeds the ability of plants to absorb, algae will start to grow. In this study, an LED device that can emit the light needed by the plants will be developed. The light emitted by this device will be adjusted to the types of plants grown and the light around the aquarium environment. In this study, an application based on an android smartphone will also be developed. This will be used by users to choose the intensity of light that will be emitted by the device according to the type of plants grown in the aquarium. The device developed has been successful in maintaining the light emitted according to the light needed by the plants and the influence of light around the aquarium.

Abstract
The transformation of sensory description of vanilla extract after it reaches the expiration date is caused by the changes in its flavor compounds. The aim of this study is to analyze the density, flavor compounds and sensory description in vanilla extract before and after the expiration date, quantitatively. Densities were measured using density meter, flavor compounds were measured using gas chromatography-mass spectrometry (GC-MS) and sensory descriptions of vanilla extract were observed using the sensory analysis of Quantitative Descriptive Analysis (QDA) by trained panellist. The results showed that the density of vanilla oleoresin increased during storage. Moreover, the GC-MS results showed that there were several flavor components that only existed on expired samples, such as 4-methyl guaiacol, anisyl ethyl ether, and anisic acid. However, there was no significant difference in vanilla extract sensory description, except for anisic attribute, where the expired vanilla extract was more anisic.
