Published: August 2021

Education is an important capital for a person to live his life. The role of education is inseparable from the components of students, teachers, learning materials, learning media, learning models, and so forth. The main factors in the education described need to be improved because the progress of the civilization of a society or nation lies at the level of education. This research is also motivated by the low level of student activity during the learning process. The low student activeness is due to the way the teacher delivers the material and the educator rarely applies varied strategies in the learning process. So the learning process becomes monotonous and boring and causes students to assume that the fiqh lesson is not important and saturating, or they think it is enough to listen to the fiqh lesson as it is finished just like that, without any application. One strategy that can be used is to implement a joyful learning strategy or fun learning. This study aims to determine whether there is an influence of joyful learning strategies on student activity in the fiqh learning process especially in circumcision material at MI Miftahurrohman Senori Tuban. This type of pre-experimental research with the type of one group pretest-posttest design. The population in this study were class V students consisting of one class that was used as an experimental class with a total of 14 students and all members of the population were sampled in this study. Data collection techniques were observation, tests (pretest and posttest) and documentation. The results of the study and discussion of the t test calculations obtained that thitung = 2.197 and ttabel = 1.771. This means that thitung is greater than ttabel so it can be concluded that there is an influence of joyful learning strategies on student activeness in the learning process of fiqh in MI Miftahurrohman Senori Tuban class on circumcision material after being treated. Increased student activity is influenced by the use of learning strategies.

Of the 4 treatment combinations were repeated 5 times, in order to obtain 20 experimental units, each containing 40 plants. Data were analyzed by ANOVA followed by the 5% HSD test. The results showed that there was a significant interaction effect between the varieties and the application of Trichoderma sp. on the growth rate of sprouts and the number of leaves grown on land with an average salinity of 4 dS.cm-1 at 35 days after planting. Anjasmoro variety shows tolerance on saline soil, while Demas 1 variants are intolerant to saline soil. Anjasmoro varieties treated with Trichoderma sp. compost were able to show a sprout growth rate of up to 6.10 cm per day and accelerate the appearance of flowers on high salinity soils. The combination of these two has the potential to be tested and developed into a wide production stage on high salinity swamps.

Published: August 2021

Today the internet is inseparable in the life of modern society. For this reason, fast and reliable internet is very important. To achieve this, on the internet there are various kinds of technologies that make it very reliable. One of the technologies used in the internet is the Multihoming Border Gateway Protocol (BGP). This BGP technology allows every router on the internet to be connected and exchange routing information needed on the internet. BGP Multihoming allows two or more Autonomous Systems (AS) to connect and exchange routing information without any routing information being wrong. So if there is one AS experiencing interference then it will not significantly affect the other AS. That is because there are two or more pathways that can be traversed to get to the destination AS.

Astrans Putra Logistik Ltd. is a logistics service company with shipping routes in Sidoarjo, Denpasar, Lombok and NTB. Some of the problems that occur, such as delays in the pick-up process of goods to the load that large but not enough for departure, cause the quality of the supply chain system to be poor. So this research needs to be done with the aim of knowing the point of waste in the supply chain, identifying the sigma value, and determining the priority for its improvement. Quality improvement is carried out using the Lean Six Sigma method with AHP integration as a priority selection for improvement. From the research results, it was found that there was waste that caused 3 (three) CTQ, namely delivery was delayed, goods were damaged or leaked, and there was a difference in the number of goods. The company's DPMO value is 34272 with a sigma value of 3.34. The priority for improvements that can be made based on AHP weight, namely check the package packages before they are sent (0,353), make SOP for the preparation of goods (0,167), and apply SOP for goods checking documents (0,142).

The car accident while passing on the railroad tracks is not new anymore. Several assumptions emerged about the cause of the breakdown of the car. Some say it's because of the magnetic field that arises from the friction between railroad iron and railroad wheels. Various internet sites have discussed the problem of car accidents that often occur at train crossings, but do not include the cause of the accident. Logically, it is true that the friction between two metals will cause something that according to physics is called thermal energy in the form of heat. The heat generated by the friction of the railroad tracks and wheels is certainly not the cause of these accidents. In several previous studies, it was stated that the friction between the wheels and railroad tracks causes changes in the earth's magnetic field. The change in the earth's magnetic field is not yet known whether it affects the performance of a car engine. This research will look for the effect of changes in the earth's magnetic field on the performance of car engines. The engine performance under study is to compare car engine speed between car engine speed data due to changes in the earth's magnetic field with car engine speed data without the influence of changes in the earth's field using the t test method for two paired samples. The results of the data test show that changes in the earth's magnetic field do not affect the performance of a car engine speed.

Carburizing is a process of adding carbon content in steel by using solid media. This study aims to determine the effectiveness of the carburizing process on the hardness and depth of carbon diffusion on ST 42 steel with a variety of donor media. Meanwhile, the donor media used were teak wood charcoal, coconut shell charcoal, and graphite. The results of this study are the highest level of hardness in coconut shell charcoal, namely 815.39 HV, teak charcoal 715.5 HV, and the lowest hardness is graphite at 343.975 HV. While the highest average carburizing depth was coconut shell charcoal of 0.0133 µ, teak charcoal at 0.0085 µ, and graphite by 0.00416 µ. This shows that there are differences in the hardness value and the depth of carbon diffusion in the three types of donor media used in the carburizing process, so it can be concluded that the type of donor media can also affect the effectiveness of the carburizing process itself.
