Abstract

One of the drawbacks of Crude Palm Oil (CPO) biodiesel is that it has a high pour point which causes disadvantages in its use. The objective of this research was to obtain biodiesel of low pour point by mixing CPO biodiesel with Candlenut biodiesel with various ratios among them. In this research, the effect of biodiesel composition, and the type of biodiesel in the mixture were evaluated in order to obtain the best combination of the biodiesel in the mixture. The influence of polyunsaturated such as linolenic derived from candlenut oil was also evaluated. The result of the research showed that when the amount of the Candlenut biodiesel increased in the mixture the pour point decreased. When the ratio between CPO and Candlenut biodiesel was 80:20, the product had an optimal pour point of – C. In fact, .the number of double bonds present in linolenic acid had a more significant effect on the quality of biodiesel produced than the length of the fatty acid chain.

Abstract

Passive design is a way to save energy through the passive use of solar energy, that is, without converting solar energy into electrical energy. the passive design relies more on the ability of engineers how the design of the building itself can "anticipate" external climate problems. In Indonesia as a tropical region, cooling systems and lighting systems are the largest contributors to building energy consumption, accounting for 24.7% and 16% respectively of the total building energy consumption. The purpose of this research is to do storage modeling using the passive energy method. The procedure is carried out with a combination of energy calculations around storage and CAD. CAD software is used to create 3D solid surface drawings and shapes. Then draw several options for the air openings that will be used. The results showed that based on the month of observation, the value of heat energy that occurred in the storage of dry harvested grain and rice with passive energy buildings was lower and heat energy was higher in June. Therefore, the solution for choosing the type of opening in January is required an opening percentage of 25% and for June, an opening with a percentage of 50% is required).

Abstract

In the era of society 5.0, skills are the most important value for a person, because skills can help them develop themselves holistically, prepare them for the world of work, and enable them to contribute positively to society. Implementing MBKM in learning is expected to meet the needs of graduates who are ready to face the world of work. By implementing MBKM, it means giving students the freedom to design collaborative projects and choose their own learning partners, MBKM facilitates innovation and co-creation. This research is a quantitative research that collects data through questionnaires and interviews. The highest increase was in independent learning skills, namely an increase of 45.3% and the smallest increase was in critical thinking skills, namely 37.3%. But basically every skill has improved. Skill improvement has an average of 41.8%. Thus, MBKM-based learning is expected to provide greater opportunities for students to take control of their own learning, develop their interests and talents, and better prepare themselves for future challenge.

Abstract

Electric vehicles use an electric motor as a driving force where it functions as a converter of electrical energy stored in the battery into mechanical energy to turn the wheels of the vehicle. Electric motors can reduce fuel consumption and air pollution produced by motorized vehicles, so electric vehicles are one of the transportation modes they can use. In this research, the design of a BrushLess Direct Current (BLDC) motor as a motorcycle propulsion was carried out. The BLDC motor has the main components, namely the stator and rotor. This electric motor designed uses a BLDC type E-BIKE with specifications for 1000 Watt power and an input voltage frequency of 60Hz, and a rotating speed of 500Rpm with a 3.75V-25Ah BMS battery in 16 series to 60V-25Ah. This E-BIKE type BLDC electric motorcycle model can be adapted to the shape of a motorcycle drum with a wheel diameter of 17 inches.

Abstract

Penelitian ini dilakukan untuk memberikan penjelasan tentang studi eksperimental pengaruh variasi beban dan variasi aliran terhadap efek water hammer. Dimana efek ini akan mempengaruhi tekanan air yang akan dihasilkan jika setelah pembebanan dan perubahan bukaan valve yang diberikan akan menghasilkan efek water hammer yang lebih baik atau cenderung lebih buruk bila tidak memiliki kedua efek tersebut. Penelitian ini dilakukan dengan melakukan studi eksperimental yang bertujuan untuk mengetahui tekanan yang terjadi pada saat air mengalir dan kemudian ditutup secara tiba-tiba oleh katup pembuangan yang dihubungkan dengan aliran pipa dengan diameter 1,5 inci setelah beban dan variasi bukaan katup. Pada uji efek water hammer dengan sistem pompa water hammer hidrolik ini dimungkinkan untuk mengubah bukaan katup pemasukan air dengan perubahan beban katup yang diberikan untuk menentukan tekanan water hammer maksimum 378334,64 Pa setelah menerima katup bukaan 80 derajat dan tambahan beban 250 gr, dan efek water hammer terkecil dengan nilai 321376,44 Pa pada bukaan katup 50 derajat dan beban 150 gr. Saat menginvestigasi pompa hydraulic ram ini, dapat disimpulkan bahwa ukuran bukaan valve atau jumlah air yang masuk dan besarnya beban pada discharge valve yang akan mempengaruhi tekanan akan meningkat.

Abstract

The Shredded fish is produced by machines automatically, which can facilitate the production process. Previously the process was done conventionally in one production run. This problem prompted researchers to create a machine by combining three tool systems to become a shredded fish processing machine, including a system for separating meat and fish bones, a cooking furnace system, and a shredded dryer/spinner system that can be controlled electrically in the production process, in addition to the shredded produced more cleanly and efficiently in one production process. This machine utilizes the power of an electric motor of ¾ Hp, which is the driving force for the meat separator machine with a rotation speed of 2840 rpm and a production capacity of 30 Kg/hour.

Abstract

The bread machine is also a leverage to increase production capacity and production quality. In contrast to manual bread production, which requires a lot of effort and time, a bread machine makes everything more efficient. The bread machine's output is better than manual production's. Besides that, the hygiene of the bread produced is guaranteed. The device is sterile and safe because all materials are protected with stainless plates, a mixer motor flame that can be adjusted according to needs, and an automatic oven according to requirements. The tray uses hygienic, not harmful to health, and environmentally friendly and pollution-free materials. The level of safety in use is higher because it has appropriate dimensions. The technique for operating a semi-automatic bread-making machine with a production capacity of 4 kg requires 45 minutes with an oven process temperature of 100 ºC to 150 ºC.

Abstract

Utilization of natural energy sources such as solar thermal energy and geothermal energy converted into electrical energy through appropriate technology has been widely used and cannot be separated from the climate. One of them is the process of drying clothes. The drying process used by many people is still simple, namely by drying directly under the sun. This method is less effective because it takes a long time and still depends on the weather. So from here, we will innovate in making a clothes dryer that uses a heating element as a heat source and a fan. The purpose of using a heating element and fan is to help speed up the process of drying clothes in a short time without having to wait a long time and to be able to control the temperature of clothes.
