Abstract

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.

Abstract

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.

Abstract

The use of gadgets, especially smartphones and tablets, for young children has now become a public concern. This is because gadgets have become a necessity for society and even children. Gadgets are technology that have very interesting applications and features, such as games and videos which children really like. Most parents do not supervise and regulate their children's use of gadgets and sometimes parents are not aware that their children are addicted to gadgets. This research aims to analyze the influence of gadget use on young children, with research subjects being carried out on Tunas Harapan Salo Kindergarten students. The results of the research show that the negative impacts are more pronounced in Tunas Harapan Kindergarten students where they show attitudes such as being easily emotional, imitating movements and language in the games or videos they see, and when using gadgets, they don't care and ignore the surrounding conditions, they don't care. care if called while playing gadget. However, even though the negative impacts are more visible, there are several positive impacts from using gadgets, namely that they can learn traditional gymnastics and dance movements through YouTube videos

Abstract

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.

Abstract

It is known that the income earned by breeders is still not optimal, so it is quite difficult to obtain higher profits. Based on the problems in this study, how to analyze factors of production, total costs, income, business efficiency and Break Event Point broiler farms in partnership Pokphand chickens and how business development strategies can be applied. This study aims to analyze the advantages of Mitra Pokphand Chicken Livestock to then determine the right development strategy by utilizing the strengths and opportunities that this livestock business has. Data analysis was carried out qualitatively and quantitatively. The data that has been obtained is analyzed using descriptive analysis, business analysis and SWOT analysis using the IFE/EFE matrix. The results showed that the size of Mitra Pokphand's business income was influenced by revenue and production costs. For breeders to increase their income, it is hoped that livestock owners can reduce production costs. Meanwhile, based on the SWOT analysis IE matrix, the broiler business in Mitra Pokphand Chicken Livestock is in cell IV position which indicates that the strategy needed for the business is to grow and develop (growth and build). This strategy shows that livestock businesses need strategies to grow better and to develop broiler farming businesses to be better.

Abstract

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.

Abstract

The development of development in the industrial world does not escape the use of building materials, one of which is asphalt, which is often used in road construction. Asbuton is one of Indonesia's natural resources whose quality cannot be doubted. One of the asbuton technologies that is widely used is pre-mixed asbuton. Pre-mixed asphalt is one type of modified asphalt used in Indonesia. Pre-mixed Asbuton is processed and mixed with Asphalt Pen 60/70 in a factory that meets certain requirements, so it is equivalent to Modified Asphalt. This research aims to obtain a comparison of the characteristic values of Premixed Asbuton (AC-WC) with Pen 60/70 Oil Asphalt (AC-WC). The method used is experimental by carrying out laboratory tests. The test results for Premixed Asbuton (AC-WC) stability were 1,239.2 and Flow 3.82. Meanwhile, Asphalt Pen 60/70 (AC-WC) Stability is 1,051.4 and Flow 3.17
