Abstract

The heat transfer is important in engineering field and aspects of the life. Many equipment was made by using principles of the heat transfer, like: the oven, iron, the car machine, the muffler, the room cooler et cetera. The principle of the work in the research, there was the heat source at the upper side and the sink (heat remover) at the bottom side so that the temperature different ( was significant) along metal that was tested. The heat source from the electric heater,the object the test togethered with his heater all was isolated. The test object consisted aluminum with 20 mm2 cross section area, the steel and copper have 10 mm2 cross section area. The results that that the conductivity of copper was biggest were followed with aluminum and finally the steel.

Abstract

Pseudomonas aeruginosa merupakan bakteri Gram negatif dari keluarga Pseudomonasadaceae dan terkenal dengan ketahananya yang mampu beradaptasi diberbagai lingkungan, suhu, bersifat aerob dengan mengoksidasi substrat untuk memperoleh energi, dapat bergerak menggunakan flagel dan tahan terhadap berbagai jenis antibiotik. Salah satu tindakan yang dapat dilakukan untuk mengurangi resistensi antibiotik yaitu memanfaatkan tanaman yang berkhasiat sebagai obat. Tujuan dari penelitian ini adalah untuk menguji efektifitas antibakteri ekstrak kulit pisang kepok (Musa acuminata balbisian colla) dan ekstrak daun salam (Syzygium polyanthum) terhadap pertumbuhan bakteri Pseudomonas aeruginosa. Jenis penelitian yang digunakan yaitu true eksperimental post test only with control group design. Metode yang digunakan difusi cakram menggunakan media Nutrient Agar (NA), sampel dibagi menjadi tiga kelompok dengan perbandingan konsentrasi ekstrak kulit pisang kapok dan daun salam (F1 25%:75%) , (F2 50%:50%) , (F3 75%:25%), kontrol positif (kloramfenikol 3µ), kontrol negatif (DMSO 5%), pengulangan dilakukan sebanyak 3 kali. Hasil pengujian yang telah dilakukan menunjukan pembentukan zona hambat pada ketiga perlakuan dengan hasil rata-rata F1 5,2 mm , F2 4,1 mm, F3 3,2 mm. Zona hambat terbesar terbentuk pada K+ , pada kelompok perlakuan zona hambat terbesar yaitu F1 kategori zona hambat lemah sampai sedang yang artinya kelompok perlakuan tidak efektif dalam menghentikan penyebaran bakteri Pseudomonas aeruginosa.

Abstract

The analysis of machine vibration is therefore essential for predictive maintenance and condition monitoring. Modern approaches, ranging from time-domain measurements of acceleration, velocity, and displacement to frequency-domain and modal analysis. This study investigates the vibration characteristics of rotating equipment in a manufacturing environment, focusing on identifying dominant frequencies, evaluating amplitude trends, and assessing overall machine condition. Data collected from accelerometers mounted on a centrifugal pump were processed using time-domain and frequency-domain techniques. The results highlight clear signatures of imbalance and bearing wear, demonstrating the value of predictive maintenance based on vibration monitoring. As the result the amplitude–frequency spectrum demonstrates that the machine is primarily influenced by rotational imbalance, with minimal evidence of high-frequency faults.

Abstract

Electricity has become an inseparable part of life's necessities along with the rapid development of technology, industry and information. The reduction in fossil energy sources and increasing awareness of preserving the environment requires us to look for alternative energy from renewable energy sources. The use of solar energy as a renewable energy source in NTB has not been widely used. This counseling was carried out at SMKN 1 Selong with the aim of introducing solar energy. Solar energy produced by solar panels is converted into electricity. Electricity is stored by the battery through a charging regulator (SCC). The battery can be used to power AC lights using an inverter. The length of use time depends on the amount of lamp power and battery power. Maintenance carried out regularly: 1. Clean the solar panels from dust or dirt. 2. Check the battery water level. Work safety is highly recommended when carrying out maintenance by turning off the MCB switch while the solar panels are being maintained.
