Resy Kumala Sari, Raka Tabagus, Muhammad Nur, Yi-Lang ChenShow Abstract | Download PDF | DOI: 10.31004/jestm.v3i2.112 | Check in Google Scholar
The aims of this research are: 1. Able to design and build functional and ergonomic trolleys based on anthropometric data. 2. Able to demonstrate the efficiency of physical products from trolleys to material handling aspects. 3. To make products that can facilitate the transportation of waste to temporary waste disposal sites (TPS).Data collection was carried out by conducting interviews and measuring the body dimensions to 20 respondents consisting of 10 industrial engineering students class of 2018 and 10 random respondents aged 22-57 years. For the design of the trolley, there are 4 data variables that will be used, namely LB (44 cm), TPB (101.90 cm), JTD (63.10), PTT (16 cm) and several additional parts to make it more ergonomic and efficient. The conclusions of this study are 1. The design and manufacture of the trolley is in accordance with the anthropometric size of the human body where the trolley is very functional by providing a pulley on the trolley so as to facilitate the process of moving to the four temporary garbage disposals (TPS) and providing 3-axis wheels which function to facilitate the collection of waste through the stairs. Thus reducing complaints of diseases such as injuries to muscles, tendons, ligaments, nerves, cartilage, bones, or blood vessels in the hands, feet, neck, and back. 2. The physical product of the trolley is in accordance with anthropometric aspects and the trolley is also more efficient in its use.

Lailatul Syifa Tanjung, Resy Kumala Sari, Hidayati RusnedyShow Abstract | Download PDF | DOI: 10.31004/jestm.v3i2.106 | Check in Google Scholar
This research aims to design a website-based User Interface that will be used to view product sales in the Postpaid Management Department. This research is important because a good User Interface can increase user efficiency in accessing and managing product sales data, which in turn can improve department performance. The research methodology used in this research is user needs analysis, User Interface prototype development, prototype testing, and user evaluation. Product sales data from the Postpaid Management Department will be used as a data source in developing the User Interface. The research results show that the User Interface design meets user needs and allows users to easily view product sales data. This User Interface provides various features that allow users to search, filter data, and view sales reports with various parameters that can be adjusted. Users also provide positive feedback regarding the ease of use of the designed User Interface. This research makes a positive contribution to the Postpaid Management Department by providing a more efficient tool in viewing product sales. The results of this research can also be a basis for further development in improving the User Interface and its functionality in accordance with the development of departmental needs.

Analysis of the Use of Generators and Rectifier Regulators as Additional Charging Systems for BLDC-Based Electric Bicycles
Nurul Dwi Pratiwi, Rahmadis Muhammad, Aris FiatnoShow Abstract | Download PDF | DOI: 10.31004/jestm.v3i2.114 | Check in Google Scholar
The development of technology and mobility has encouraged humans to innovate and create environmentally friendly means of transportation and can reduce dependence on fuel oil which will eventually run out. Currently, transportation equipment using electrical energy is starting to appear as an alternative energy source, including electric bicycles. In this research, electric bicycles were produced equipped with generators and rectifiers to produce additional electrical energy. The generators utilizes the rotation of the front wheels to produce electrical energy which is then channeled through the rectifier and stored in the battery. This research aims to determine the benefits of using generators and rectifiers as additional charging systems for BLDC-based electric bicycles by conducting direct road test of electric bicycles. The result show that the use of a generator and rectifier can increase the distance traveled by up to 2 km. An electric bicycle with a capacity of 24V x 14 Ah can over a distance of 13 km without a generator and 15 km with a generator.

Forage is the main feed for ruminant livestock. Before starting a ruminant livestock business, farmers need to plan the availability of forage before the ruminant livestock are brought to the livestock location. The main feed for ruminant livestock comes from consuming fresh forage ranging from 10-15% of the livestock's body weight. One of the superior grasses used as animal feed is setaria grass (Setaria sphacelata). Increasing the productivity of superior grass is influenced by several factors, including seeds, climate, weather, water and fertilizer. Manure is a product made from livestock waste that is given to agricultural land to improve soil fertility and structure. This research aims to determine the effect of giving cow manure on the growth of plant height, leaf width, leaf length, and the number of setaria grass saplings. Application of cow manure resulted in a significant increase in plant height, leaf length and fresh weight of setaria grass. The best results were found in the P2 treatment, namely by providing 300 grams of cow manure per planting hole.

Analysis of Environmental Traffic Flow Characteristics on Jalan Kaharuddin Nasution – Marpoyan, Pekanbaru City
Revi Lasmita, Ayu Putri Permata MS, GusnandaShow Abstract | Download PDF | DOI: 10.31004/jestm.v3i2.129 | Check in Google Scholar
Jalan Kaharuddin Nasution, a major educational area in Pekanbaru, hosts numerous schools and universities along with various amenities such as hotels, restaurants, cafes, shops, and street vendors. This study focuses on three key traffic components: Speed, Volume, and Density, aiming to analyze service levels on Kaharuddin Nasution Street. The research investigates the relationship between traffic flow components (Volume, Speed, and Density) using the Greenshield and Greenberg Models. Findings reveal that the Greenshield Model best portrays congestion density (Dj), ranging from 103.17 to 126.41 vehicles/km, compared to Greenberg's much higher Dj values (642.89 – 3990.35 vehicles/km). Greenshield also identifies maximum volume/capacity (1801.74 – 2562.53 vehicles/hour), while Greenberg shows higher capacity (3477.38 – 12826.50 vehicles/hour), inconsistent with the road's actual capacity. Service levels on Kaharuddin Nasution Street throughout the week are categorized as E, indicating service levels beyond speed measurement due to consistently lower speeds than level D. Unstable traffic results from near-capacity volumes, causing congestion and occasional standstill. Effective traffic management considering volume, speed, and density is essential to anticipate future congestion issues on Kaharuddin Nasution Street.
