Published: February 2021

Abstract
Creativity and Sustainability Education (Education for Sustainability Development) are two global agendas in 21st century learning. This underlies the birth of various pedagogical ideas that are relevant for teaching creativity and eco-literacy. Humans are creatures who love to play (homo ludens) and will always desire to be affiliated with nature (biophilia). Therefore, this article aims to describe how creative play and learning in the natural environment are used to develop creative-eco-literacy in elementary school students. This article presents an overview of Participatory Action Research (PAR) studies in social studies teaching. Kemmis, McTaggart, and Nixon (2014) defined PAR as a study, which creates learning innovation through planning, action, observation, and reflection. The teacher makes learning plans by preparing various creative games performed in the natural environment such as playing on grass, identifying colors, shapes, textures of plants and animal, natural sounds, describing, asking, telling about animals, running, digging, and solving environmental problems such as through gardening activities. The teacher does not forget to make the relevance of these activities with the curriculum that applies in the school thematically. Learning activities are then observed and reflected by the teacher to see their effectiveness and impact on students creative-eco-literacy development. The results showed that creative play activities and learning in the natural environment can be used to develop adaptive, aesthetic, cognitive, communication as a language function, sensorimotor, and socio emotional attitudes in students.

Published: February 2021

Abstract
The problem of global warming or called GWP (Global Warming Potential) that occurs in the earth’s atmosphere, one of which comes from synthetic refrigerants used in household air-conditioning refrigeration machines. R410A is a refrigerant that still contains GWP: 1942. Hydrocarbon refrigerant is a refrigerant that does not contain ODP (Ozone Depleting Potential) and a very small GWP. By using ref prop software, the mixing process can be simulated to obtain refrigerants that have characteristics similar to R410A. Mixing using R32 / R290 ingredients varied with percentage compositions ranging from 50/50, 40/60, 30/70, 20/80, and 10/90. From the simulation results, a mixture approaching R410A with 10/90 composition with COP: 3.85 for R410A and 5.76 for 10/90 mixture was obtained. Compression ratio: R410A: 2.8 and for mixed refrigerants 10/90: 1.8. The refrigerant effect of mixed refrigerants is 10/90: 264,13, R410A: 161,68. By using this refrigerant mixture can reduce the GWP and improve the performance of the Air Conditioning cooling system so that it has a reduced GWP value that can be obtained significantly and has a large enough potential to replace the R410A.

Abstract
One of the factors that influence the smoothness in the Production Process is the condition of the equipment or machine. Frequent jams or even the engine may stop suddenly making the readiness and reliability of the machine is not optimal, causing production losses and quality degradation. For this reason, engine maintenance becomes a very important thing to consider in order to maintain the ongoing level of productivity. Oni Jaya Motor is a company engaged in manufacturing that produces motorcycle spare parts. This company is inseparable from problems related to the effectiveness of equipment or machinery. One of the causes of disruption to the production process is due to the lack of maintenance management on the machine. To overcome this, one of the methods used to measure engine effectiveness is the Overall Equipment Effectiveness (OEE) method. Where is known the value of OEE can provide information in evaluating maintenance activities so as to minimize the occurrence of lost production and decreased quality. The results of calculations with the OEE method on Oni Jaya motorcycles are carried out on the Corter Machine and take place from January 2018 to December 2018 with the highest OEE value of 81.0%, while the lowest OEE value of 77.1%. Based on the results of data processing and identification of the six big losses, the most influential losses on the machine are set up and adjustment of 29.8%, Reduced Speed Loss of 25.6% and Breakdown Loss of 21.3%.

Published: February 2021

Abstract
Severe accidents on the Gekbrong - Bangbayang road, Cianjur, very often occur and recur with the same pattern of events, which caused quite a lot of victims, in the form of property and lives. Handling of Field existing in n the form of making the ramp on the left side of the road, intended to halt vehicles that have failed brakes. This handling is certainly not rooted in the main problem, namely the steep geometric conditions of the road. Based on the data, the accident occurred on a vehicle that descended towards Cianjur. Failed brakes on vehicles that crashed on this road due to steep long descent. This geometric condition causes the driver - which is not normal through this section - to do continuous braking, which causes the brake lining to run out or the hydraulic brake system to be damaged, which in turn results in a severe accident. This situation can be avoided by improving the geometric conditions of the steep road, by changing the road alignment for vehicles going down towards Cianjur. Road alignment deflected in Gekbrong (KM 78 + 000) to the left, customized topographic data were made 2-3 bends, and end it merged back into the main line in Bangbayang (KM 74 + 000). While vehicles that ride towards Sukabumi continue to use existing roads with some geometric improvements, unless heavy vehicles are prepared for special lanes following the new road alignment.
