Currently the current curriculum is being discussed, namely the curriculum based on the Indonesian national qualification framework (KKNI). This curriculum is very closely related to the HOTS system (High Order Thinking Skill), where this system requires students / students to think high-level that requires a variety of different learning and teaching steps by just learning facts and concepts alone. The KKNI curriculum requires students to go directly into the real world / field. This curriculum is also expected to be able to harmonize cognitive, psychomotor, and affective. The purpose of this study was to find out and analyze how the influence of KKNI on the quality of student learning. Data collection techniques are by distributing questionnaires to respondents as many as 40 respondents. The research method used in this study is by using a correlational method that is related to the descriptive method, where the writer will look for the relationship between the variables studied, namely the KKNI towards the quality of student learning. The research approach used by the writer is by using qualitative and quantitative approaches. The results showed that there was an influence of the KKNI curriculum on the quality of student learning.

It has been observed that with increase in mass flow rate, air outlet temperature decreases and freezing time of cylinder decreases. However, at constant mass flow rate, with increase in cylinder radius, air temperature decreases and while freezing time increase sharply.

The results showed that early childhood in the application of science literacy as a learning development program in the classroom requires three aspects that need to be considered, namely: attitude, skills, self-competence in children's cognitive ability, and participation in classroom strategies mapped by teachers. While the needs of learning in the classroom are very important to be done as an effort to improve the competence of teachers to the quality of teaching.

To enhance the heat transfer rate, two different types of roughness has been used in conical insert i.e. protrusion and dimple roughness. A three-dimensional computational model with  RNG turbulence model is used for the simulation and it has been performed for three different diameters (3 mm, 6 mm and 9 mm) and two different pitch space (120 mm and 180 mm) for both protrusion and dimple roughness. The present model has been validated with Dittus-Boelter equation and with Blasius equation for Nusselt number and friction factor, respectively. For a constant heat flux of 1200 W/m2, effect of roughness, diameter and pitch on Nusselt number and friction factor has been predicted for Reynold number range of 5000 to 30000. From the result, it is found that, the protrusion shaped roughness has better thermal performance factor than dimple shape and diameter of 6 mm has performed better than 3 mm and 9 mm for both the cases of roughness due to favorable flow dynamics.","PeriodicalId":143921,"journal":{"name":"Aptisi Transactions on Technopreneurship (ATT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122942407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Krukut river is one of the rivers that often overflow, which is one of the causes of flooding in Jakarta. This study aims to determine the water level of the Krukut river so that it can be used as a reference in handling flood disaster mitigation. This study uses the Nakayasu method and the Snyder method to calculate flood discharge, with a return period of up to 100 years. Meanwhile, for modeling the river water level using the HEC-RAS 5.0.07 application. The results of this study, specifically on the upstream cross-section until 300 meters after that TMA, are pretty high with plan one, which is 3 m deep from the bottom of the channel. However, the track still has a sufficient guard height of about 1.5 m. In other words, no overtopping/ river water does not overflow in the upstream area with a return period of 10 years and 25 years. However, due to the narrower channel section, the upstream region is more prone to flooding than the middle downstream area. From the modeling results, the channel prone to erosion is the section 10 track which is widening at the same time that the channel is not filled with the CONCRETE channel, so it is effortless to erode. For this reason, it is recommended to repair the walls of the river/channel to avoid scouring, especially if there is a high/extreme discharge.","PeriodicalId":143921,"journal":{"name":"Aptisi Transactions on Technopreneurship (ATT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132644350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
