Penajam Paser Utara ini mempunyai segudang destinasi wisata yang berpotensi untuk dikembangkan. Namun, pemberitaan terkait destinasi wisata yang ada pada Penajam Paser Utara sangat jarang didengar oleh telinga para wisatawan dari luar daerah Penajam Paser Utara, salah satunya ialah destinasi wisata Pantai Tanjung Jumlai yang memiliki potensi untuk dikembangkan. Dari data yang didapat oleh peneliti, Pantai Tanjung Jumlai sangat terdampak karena adanya pandemi Covid-19, akibat dari hal tersebut pada masa pandemi Covid-19 terjadi penurunan jumlah wisatawan yang datang merasakan keindahan dari Pantai Tanjung Jumlai ini sendiri. Pembuatan jurnal ini mempunyai maksud sebagai penyebar luas informasi dalam bentuk media tulis ke sejumlah pembaca yang ingin mengetahui lebih jauh lagi terkait destinasi wisata yang berada di calon Ibu Kota Negara baru, Penajam Paser Utara, tep...

Pelatihan ini dilakukan karena kekurangan jumlah pelatih KSN, sedangkan ajang ini sangat bergengsi bagi para siswa SMA di seluruh Indonesia. Oleh karena itu, pelatihan ini diadakan untuk mempersiapkan para siswa menghadapi KSN 2020. Pelatihan ini menggunakan metode pembahasan soal secara intensif. Tahap-tahap yang dijalani adalah pre-test, pemantapan materi dasar KSN, pelatihan soal secara intensif, dan diakhiri post-test dengan soal-soal yang sebobot dengan pre-test. Pelatihan dilakukan secara luring dan daring. Hasilnya adalah salah seorang siswa binaan berhasil mendapatkan juara pertama KSN pada tingkat kota Balikpapan dan juara pertama babak penyisihan tingkat kota Balikpapan pada Pekan Fisika XXI Universitas Mulawarman. Hal ini membuktikan bahwa dengan adanya pelatihan KSN secara intensif oleh pelatih KSN yang mumpuni maka peluang juara semakin terbuka ...

Setiap SMA di Balikpapan sebagai mitra pengabdian dihimbau mengirimkan maksimal tiga siswa terbaiknya untuk mengikuti program ini. Pembinaan dilakukan intensif dengan metode daring, baik secara asinkron maupun sinkron. Pembelajaran asinkron dilaksanakan dengan memberikan berbagai soal latihan Fisika dari level sekolah hingga tingkat olimpiade secara bertahap melalui penggunaan Google Classroom, sedangkan pembelajaran sinkron dilakukan untuk membahas soal-soal tersebut serta memantapkan konsep dasar materi KSN Fisika melalui penggunaan Google Meet untuk piranti pembelajaran sinkron dan Google Jamboard untuk piranti notulensinya. Tingkat keberhasilan program diukur dengan pre-test di awal pembinaan dan post-test di akhir pembinaan dengan bobot soal yang setara. Ada lima topik yang diujikan...

Bertolak dari pemikiran Richard Feynmann dan David Deutsch, diperlukan komputer yang bekerja berdasarkan prinsip-prinsip mekanika kuantum yang berbasis dua keadaan juga. Beberapa penelitian membuktikan bahwa algoritma-algoritma kuantum mampu menyelesaikan beberapa persoalan yang belum bisa diselesaikan oleh komputer klasik secara efisien. Komputer kuantum berbasis NMR diperkenalkan sebagai prototipe pertama dari sistem fisis dimana algoritma kuantum berskala kecil dapat dijalankan. Akan tetapi banyak jurnal penelitian telah membahas hasil eksperimen tanpa disertai perhitungan secara terperinci hingga dimunculkannya spektrum absorpsi. Tesis ini bertujuan untuk mengkaji perhitungan matematis mengenai algoritma Deutsch-Jozsa 3 qubit pada sistem fisis NMR. Hasilnya terbukti bahwa algoritma ini dapat diterapkan secara teoritis.

The quantum system replaces the role of the classical system which has a working substance in the form of gas confined in a piston cylinder. The piston that moves back and forth is substituted by a 1D potential box wall that can move freely to change the width of the potential box. In this way, the three classical thermodynamic processes in the CLE (Classical Lenoir Engine), namely isochoric, isotherm, and isobar, can be analogous to the quantum system. Finally, we find that the thermal efficiency formulation of QLE has the similarity of shape to the CLE efficiency equation. However, a higher ratio of specific heat for QLE makes the efficiency value greater than CLE at each same compression ratio.

In this theoretical study, the symmetrical potential box containing one particle with one of its walls moving freely is analogous to a cylinder with a piston. The potential box contains a massless Boson particle, while the piston-cylinder contains a monatomic ideal gas. The form of Quantum-Mechanical Brayton Engine (QMBE) thermal efficiency formulation has similarities to the classical version of the Brayton engine. However, the efficiency value of QMBE with a massless Boson particle is higher than the classic version because the heat capacity ratio of the Boson particle working fluid is 2, while the monatomic ideal gas is 5/3.

This quantum efficiency of the engine will be compared to the classical version, the gas in the piston tube, which is considered still needs to be improved its efficiency according to the second law of thermodynamics. By analogizing the variables that exist in the classical system to the quantum system, heat energy and work for the five thermodynamic processes in a quantum dual cycle can be extracted. The main result is obtained that the thermal efficiency of a dual quantum engine has similar formulations with the classical counterpart. The higher heat capacity ratio of the quantum system has the effect of higher efficiency of the quantum dual engine than the efficiency of the classical version at the same compression ratio, cutoff ratio, and pressure ratio.

This engine is often implemented on turbojet engines of airplanes and gas turbines. However, the efficiency of a classically Brayton engine still needs to be improved according to the second law of thermodynamics. This research presents a Brayton engine on 2D symmetric potential well. The used method is modeling analogy of the first law of thermodynamics and then it is implemented into a quantum system with the single-particle as a working substance. The primary result obtained is the efficiency formulation of a quantum Brayton engine for 2D symmetric potential well which is similar to the 1D quantum Brayton engine and the classical Brayton engine. Quantum Brayton engine in 2D has a higher efficiency compared to the 1D and the classical one.

The quantum system used is a single particle (as a working fluid instead of gas in a piston tube) in a one-dimensional infinite potential well with a wall that is free to move. The analogy of the appropriate variables between classical and quantum systems makes the three processes for the classical Lenoir engine applicable to the quantum system. The thermal efficiency of the quantum Lenoir engine is found to have the same formulation as the classical one. The higher heat capacity ratio in the quantum system increases the thermal efficiency of the quantum Lenoir engine by 56.29% over the classical version at the same compression ratio of 4.41.

The method applied in this research is a classical thermodynamics system model in the form of a piston tube containing a monatomic ideal gas analogous to a quantum model in the form of a potential box containing one particle. The efficiency formulation of the quantum Brayton engine obtained from this study is following the classical version. However, the efficiency value obtained on a quantum Brayton engine is higher when compared to its classic. It happens because the value of the Laplace constant owned by the Brayton quantum version is 3, while the classic version is 5/3.
