Abstract

Komposit berbahan dasar fiberglass banyak ditemui pada produksi kapal. Namun, pemakaian komposit dalam proses produksi kapal belum mempunyai ketetapan mutu yang baik tentang pengaruh antara persentase resin dan hardener yang dipakai, akan tetapi banyaknya pemakaian katalis dan resin mempunyai pengaruh pada kekuatan komposit serat sebagai penguat. Penelitian ini dilakukan untuk melihat perbandingan persentase katalis dan resin pada kuat tarik komposit berbahan fiberglass. Metode yang dipakai pada penelitian ini ialah metode eksperimen yang memakai mesin uji tarik serta meragamkan persentase katalis pada campuran resin dari 1% hingga 2,5%. Hasil yang diperoleh pada penelitian yaitu komposit dengan kandungan persntase 1% mempunyai nilai kuat tarik 99,25 N/mm2, elongasi 19,8% dan modulus elastisitas 518,18 N/mm2. Komposit serta kandungan katalis 1% mempunyai skor kuat tarik 108,65 N/mm2, elongasi 15,6% dan modulus elastisitas 11,86 N/mm2. Komposit yang mengandung katalis 2% mempunyai skor kuat tarik 108,31 N/mm2, elongasi 24,2% dan modulus elastisitas 500,52 N/mm2. Komposit dengan kandungan katalis 2,5% mempunyai skor kuat tarik 104,75 N/mm2, elongasi 19,4% dan modulus elastisitas 658,96 N/mm2. Kekuatan tarik komposit fiberglass terjadi kenaikan pada kandungan katalis 1% sampai 1,5% serta terjadi pelemahan pada kandungan katalis 2% sampai dengan kandungan katalis 2,5%. Hasil kuat tarik paling tinggi berada pada komposit dengan capuran kandungan resin 98,5% dan kandungan katalis 1,5%.

Abstract

Seringkali banyak ditemukan peserta didik yang diberi lebelling negative oleh guru berdasarkan tingkat pengetahuan dan keterampilannya. Hal ini menjadi faktor yang mempengaruhi peserta didik dalam keberhasilan menjalani pembelajaran. Karena pemberian labelling membuat seorang peserta didik tidak percaya diri. Berdasarkan fenomena yang terjadi ini, penelitian ini bertujuan untuk mengungkapkan pengaruh pemberian lebelling negative ini terhadap minat belajar peserta didik. Penelitian menggunakan metode kuantitatif dengan jenis korelasional yang menerapkan lebelling negative pada peserta didik dan melihat dampaknya terhadap minat belajar seorang siswa. Penelitian dilaksanakan pada 68 orang siswa kelas X Teknik Pemesinan di SMK N 1 Bukitinggi. Analisis data menggunakan metode deskripktif dan analisis regresi. Hasil pengujian diketahui nilai signifikan sebesar 0,037 yang artinya > 0,005. Sehingga diketahui jika Ha diterima dan Ho ditolak, artinya ada dampak signifikans antar variabel pemberian labelling terhadap variabel minat belajar siswa. Dari hasil riset ini disimpulkan bahwasanya ada kontribusi yang signifikan antara pemberian labelling negative pada minat belajar siswa. Seorang anak diberikan label negatif akan membuat anak tersebut dijauhkan dari temannya. Hal ini berdampak terhadap kepercayaan diri siswa. Seseorang yang memperoleh label negatif akan meyakini dirinya sesuai denga lebel negatif yang disematkan kepada dirinya. Hal ini sangat berpengaruh terhadap minat seseorang terhadap pembelajaran dan berdampak langsung kepada prestasi belajar.

Abstract

Based on research conducted by PISA, the ability to solve problems and think critically of Indonesian students is still below the average score set by PISA. Problem based learning is one of the learning models recommended by the Ministry of Education and Culture to be applied in improving these abilities. However, the lack of problem-based learning that has been applied so far is the lack of use of media that can be used as support in learning activities, resulting in inconsistencies in the impact of problem-based learning in improving student skills. The importance of these skills for students to have in this era of the industrial revolution 4.0, makes educators have to be more creative and innovative in implementing learning. Therefore, this study aims at seeing efforts to improve problem solving skills and critical thinking skills through problem based integrated computer assisted instruction (CAI). This study used a quasi-experimental pre-test and post-test control group design. The population in this study were undergraduate students of Mechanical Engineering Education, Padang State University. The instrument used in this research is a questionnaire which is used to see students' problem solving and critical thinking skills. The data analysis technique in this study is in accordance with the research hypothesis, where research hypotheses 1 and 2 use independent sample t-test and research hypothesis 3 uses MANCOVA. The research covered by his study is in line with higher education's continuing search for effective SCL approaches

Abstract

Stability is an important aspect that was studied in ship design as it relates to the safety of the ship when facing ocean waves. The tourist ship needed to have a good image in order to attract tourists to use its services. Good stability of the tourist ship was crucial in enhancing the image of the ship and attracting tourists to utilize its services. This research aimed to investigate the effect of concave on the U hull to improve ship stability. The study compared the stability test results of two hull designs: U hull with concave and without concave. The stability tests of both ship models were conducted through simulation methods. The simulations were performed under two conditions: when the tourist ship was empty and when it was fully loaded with passengers. The simulation results indicated that the design of the U hull with concave had a positive influence on ship stability, leading to improved stability. The concave design enhanced the ship's ability to return to its original position when encountering waves. Even in the presence of small waves, the tourist ship did not experience instability.

Abstract

The availability of boats is needed to develop fishing tourism. Most of the boats used so far generally use fishing boats made of woodcut in the forest, so this can damage the environment and cause natural disasters. Ships using a flat plate hull made of steel can be a substitute for wooden ships. This study aims to test the stability of a flat plate vessel designed for fishing boats. The ship stability test was carried out using a computer simulation method using Maxsurf Stability software. The ship stability criteria refer to the International Maritime Organization code A.749 (18), Ch 3-design criteria applicable to all ships. The ship stability analysis was carried out on two variations of the load case. The value of GZ at A h 300, A h 400 and A h 300 - A h 400 for load case 1 and 2 are greater than the minimum standards determined by IMO. The maximum GZ value at load case 1 occurs at an angle of 400 and at load case 2 at an angle of 60.90. The GM value in load case 1 is 0.609 meters and in load case 2 is 0.485 meters. Based on the results of the tests that have been carried out, it can be denied that the flatboat design model for fishing tourism meets the criteria set by the International Maritime Organization.
