Abstract

A numerical study to reduce the condenser pressure in critical areas of a power plant surface condenser has been carried out. Numerically, effects are considered through a three-dimensional simulation approach. Modifying by adding a guide plate with a three variation of angle, (?) 15?, 30?, 45? in the surface condenser area to reduce the dynamic forces and pressure due to the collision of fluid flow in the critical pipeline without reducing the purpose of the design of shell and tube heat exchanger results in transferring heat. The drag force caused by the interaction of the shear layer with the surface of the body is very undesirable, so that the control of the flow fields is needed, one of which is by optimal angle guide plate of the pipe arrangement in the critical area. This study aims to determine the optimal plate angle to overcome high pressure in the critical area. This research was numerically conducted using 3D CFD ANSYS 14.5 software with a turbulence model using a standard k-? using a pressure-based solution solver. The initial stage takes geometric data on the surface condenser in the design specification as the basis for making the domain and data from before as boundary conditions in the simulation research process. The result is that with the addition of guide plates, the average drag coefficient (Cd) is reduced compared to the average Cd in the baseline conditions and angle variation (?) 15?, 30?, 45? is 0.537; 0.644; 0.446; 0.464. Taking into this aspect, the most optimal plate angle is 30?. The simulation results show that changing the angle of the plate can reduce the Nusselt value than the baseline conditions.

Abstract

The Minimum Competency Assessment is one of the national assessments used in 2021 by the Ministry of Education and Culture to replace the high school level national exam. It focuses on measuring literacy and numeric skills through students' logical abilities and reading comprehension. To trigger an increase in logic skills, SMAN 1 Lumajang students are given additional knowledge outside the curriculum. One of them is through the introduction of microcontrollers and PLCs, namely logic-based programming devices. This activity is also able to increase digital, technological and human literacy competencies in the era of the industrial revolution 4.0 because Microcontrollers and PLCs are widely used in the field of industrial automation. From the implementation of the activity it is known that the results of the participants' quizzes on each subject matter showed very satisfactory results with an average score of 76 and the results of the participants' tests at the end of the lesson also showed satisfactory results with an average score. out of 74. In addition, the results of the participant questionnaire in response to the implementation of the activity showed very good results. With these activities, the microcontroller and PLC can be used as one of the extracurricular activities to improve the competence of SMAN 1 Lumajang students.

Abstract

Kelompok nelayan Sedati saat ini mengandalkan kapal ikan 1 GT untuk menangkap ikan di lautan. Mayoritas kapal yang dimiliki oleh nelayan sudah berbahan fiber. Dalam pengoprasiannya, sering terjadi kerusakan-kerusakan kecil pada kapal akibat benturan ataupun kandas pada tanah. Kerusakan-kerusakan ini tentunya akan mengganggu pekerjaan nelayan dalam mengangkap ikan. Oleh karenaya Nelayan perlu dibekali keahlian dalam perwatan dan perbaikan kapal berbahan Fiber, agar bisa melakukan perbaikan secara mandiri. Kegiatan pelatihan kapal berbahan Fiber akan diperuntukkan bagi kelompok nelayan di Kecamatan Sedati Kabupaten Sidoarjo. Pelatihan terdiri dari teori penggunaan kapal Fiber yang baik dan benar, teori perawatan dan perbaikan kapal fiber, teori pencampuran bahan fiber di kapal serta praktek langsung di lapangan.

Abstract

Illegal logging in Indonesia is no small problem, with illegal logging causing damage to forest resources in terms of quantity, quality and ecosystem. Many efforts have been taken by the Indonesian government, but it has not been effective in dealing with this problem, due to limited supervision. From this problem, a chainsaw sound detection system was designed as an early indication of logging activity. This system is equipped with four MAX4466 sound sensors using the Convolutional Neural Network method. This system also uses data processing so that the chainsaw sound can be recognized by the system specifically and can communicate remotely with the use of LoRa RFM95. Thus, the system can identify the sound of the chainsaw with a maximum distance of 50 m, the success accuracy of the CNN model created reaches 97.5%, and can be integrated with WhatsApp in realtime.

Abstract

Asesmen Kompetensi Minimal (AKM) merupakan salah satu asesmen nasional yang digunakan pada tahun 2021 oleh Kementerian Pendidikan dan Kebudayaan untuk menggantikan ujian nasional tingkat SMA. AKM fokus mengukur kemampuan literasi dan numerikal melalui kemampuan logika dan pemahaman baca siswa. Berdasarkan laporan hasil tes PISA pada tahun 2018, kedua kompetensi ini menjadi masalah mendasar siswa di Indonesia. Untuk memicu peningkatan kemampuan logika siswa MAN 2 Madiun, maka diberikan pengetahuan tambahan di luar kurikulum. Salah satunya melalui kegiatan workshop pembuatan automatic mobile robot. Kegiatan ini juga mampu meningkatkan kompetensi dalam literasi digital, teknologi dan manusia pada era revolusi industri 4.0 karena workshop pembuatan automatic mobile robot banyak digunakan dibidang otomasi industri. Kegiatan dilaksanakan dengan metode luring melalui tatap muka di Aula MAN 2 Madiun untuk menciptakan ruang pembelajaran interaktif. Dari pelaksanaan kegiatan, didapatkan hasil quiz peserta pada setiap pokok materi menunjukkan hasil sangat memuaskan dengan nilai rata-rata 81 dan hasil tes peserta pada akhir pembelajaran juga menunjukkan hasil memuaskan dengan nilai rata-rata 79. Selain itu, dari hasil kuisioner peserta sebagai bentuk respon dari pelaksanaan kegiatan menunjukkan hasil sangat baik. Dengan adanya kegiatan ini, pembuatan automatic mobile robot dapat dijadikan sebagai salah satu kegiatan ekstrakurikuler untuk meningkatkan kompetensi siswa MAN 2 Madiun.
