Abstract

Teaching reading comprehension to the students is not easy. The teacher often finds a lot of students’ learning motivation problems from the students. The students’ problems are (1) students’ interest, (2) students’ effort, (3) self responsibility activity or persistence, (4) students’ optimal experiences; (5) reinforcement and teacher's method. One of the efforts to minimize the problems is by empowering the students in the learning process. One of the teaching techniques that can empower learners is Reciprocal Teaching Method. An action research was carried out and aimed at finding out whether Reciprocal teaching can improve the students’ learning motivation in reading comprehension in classroom when the teacher applies reciprocal teaching. Two cycles are applied. The data are taken by observing the learning process when an action is applied, by interviewing the learners involved, by giving questionnaires and by conducting interview. The finding of the research shows that Reciprocal Teaching Method can improve the students’ learning motivation in reading comprehension when it is applied.

Abstract

Hidrofoil adalah sebuah kapal dengan bagian seperti sayap yang dipasang pada penyangga di bawah lambung kapal. Ketika kapal meningkatkan kecepatannya, hidrofoil memproduksi gaya angkat sehingga lambungnya terangkat dan keluar dari air. Ini menyebabkan pengurangan gesekan dan oleh karena itu peningkatan dalam kecepatan. Pemilihan foil menjadi salah satu aspek yang penting dalam meningkatkan prinsip kerja kapal (Adji, 2017). Geometri foil yang dirancang dalam penelitian ini diharapkan mampu menghasilkan gaya angkat (lift) yang maksimal serta menghasilkan gaya hambat (drag) seminimal mungkin pada waktu yang bersamaan. Sehingga nantinya geometri foil pada kapal hidrofoil tersebut adalah yang memiliki rasio koefisien gaya angkat (CL) terhadap koefisien gaya hambat (CD) paling besar (CL/CD maksimum). Selanjutnya proses optimasi menggunakan Particle Swarm Optimization (PSO) untuk mendapatkan nilai CL/CD maksimum. Metodologi  penelitian dilakukan melalui empat tahapan yaitu 1) penentuan sudut serang dan Bilangan Reynold; 2) penentuan foil NACA 63(3)018 3) iterasi dengan XFoil solver, 4) proses optimasi menggunakan GNU Octave 4.4.1. Hasil penelitian menunjukkan validasi pada MA409 menghasilkan nilai CL metode panel yang cukup baik dan akurat dengan rata-rata kesalahan sebesar 3.65%, sedangkan validasi untuk CD rata-rata kesalahan 9.31%. Hasil ini dalam toleransi yang diijinkan sesuai literatur Reid (2016) yaitu dibawah 9.5%. Kesimpulan penelitian adalah nilai rasio gaya angkat terhadap gaya hambat (CL/CD) maksimum dipengaruhi oleh bilangan Reynold. Semakin besar bilangan Reynold maka nilai CL/CD maksimum juga semakin tinggi. Ketebalan (thickness) dan camber maksimum hidrofoil setelah dioptimasi mempunyai kecenderungan semakin meningkat dengan peningkatan bilangan Reynold.

Abstract

SLB N Jepon-Blora is one of the special schools that accommodates all types of disabilities by providing Batik Ciprat skills. Batik Ciprat's skills are carried out at school. Still, during the Covid-19 pandemic, students learned from home so that the production of Batik Ciprat was temporarily stopped, even though there was still a demand for Batik Ciprat from consumers. The tools used by SLB N Jepon-Blora's students in producing Batik Ciprat are straightforward. “Gawangan” means spreading cloth made of paralon pipes arranged like a table frame. These hurdles are inefficient, easily damaged, require ample space in storage. The STT Ronggolawe Cepu made a portable frame from stainless steel, which is designed to be folded so that it is practical and does not require ample space in terms of storage. This program aims to see the sustainability of the STT Ronggolawe Cepu team's activities at SLB N Jepon-Blora. The program's conclusions are as follows: 1) the tools submitted by the STT Ronggolawe Cepu Team still exist and are still being used in the Batik Ciprat production process before the Covid-19 pandemic. 2) the sustainability program has encountered obstacles from external factors, such as the natural conditions of the Covid-19 pandemic, causing the production of Batik Ciprat SLB N Jepon-Blora to be temporarily suspended.

Abstract

There are 2 problems that motivated the researchers to conduct this research. The first problems arises from internal and the second comes from external problems related to the weakness of engineering students in mastering English vocabulary. This study is intended to provide reinforcement to students on English vocabulary so that their English language skills increase. Through the repetition method, students are more likely to repeat and practice correct spelling when pronouncing English words. In addition, the ability to concoct sentences can also be trained with this method. The data in the form of field notes and questionnaire results show that with repetition students are able to increase English vocabulary accompanied by an increase in creating sentences.

Abstract

Central Java Province, especially Rembang Regency, has great potential for marine resources. However, based on PRDB data for the fisheries sub-sector, from 2010 to 2021 the fishery sector has slowed down. One of the reasons for this condition is that fishermen in Rembang Regency still use small-scale capture fisheries methods. Alternative fishing patterns need to be considered to increase capture fisheries production and reduce ship fuel costs so that fishing operations can remain profitable. One way that can be done is by conducting a study on the ship's steering axis. The traditional ship steering axle uses AISI 1045 material which is hard, wear-resistant, torsional-resistant, and quite ductile at the core. This study aims to analyze the strength of the material on the steering shaft of a traditional ship using Solidworks. The method used is a quantitative simulation to analyze the strength of the structure on the steering shaft of a traditional ship including the strength of the structure, the magnitude of the force, the torque and the stress that occurs. This analysis will be useful to assist fishermen in selecting suitable materials for traditional boats. The result of this research is AISI 1045 material has a yield strength of 5.3e+08 N/m2. The traditional ship's steering axis when given a bending load of 100 N, with a torque of 10 N.m, the maximum stress is 33.64 N/mm2, so the safety factor is 5.588585. The critical stress will occur when the bending load is increased to 600 N and the torque is 60 N.m, the maximum stress is 201.9 N/mm2 and the safety factor is less than 1, which is 0.931154. The maximum stress obtained exceeds the maximum stress required by the Indonesian Classification Bureau (BKI) which is 188 N/mm2 so that the construction is said to be unsafe.
