Abstract

The hearing level of fishermen in the Lembeh Strait out of 11 fishermen, there are only 2 fishermen whose hearing is still normal. This is likely the effect of a plain exhaust modification and does not use a muffler. The muffler acts as a sound transmission damper when the exhaust gases exit the engine. The objectives of this study are as follows: 1) redesign of the engine exhaust of the pakura boat; 2) analyze the relationship and influence of rotation per minute with laboratory-scale noise levels; and 3) analyze the relationship and influence of rotation per minute with field-scale noise levels. The method used in this research is experimental laboratory and field, comparising one control group and three treatment groups. The results obtained are that there are three types of redesigned exhausts equipped with mufflers. The most effective exhaust for reducing noise levels is exhaust type B, with a range of values between 79-93 dB in laboratory scale and 90-102 dB in field scale.

Abstract

Bahan bakar merupakan salah satu elemen penting yang sangat berpengaruh dan menunjang keberhasilan kegiatan penangkapan ikan serta menjadi bahan vital bagi sebuah mesin. Namun penggunaan bahan bakar yang semakin meningkat juga akan berpengaruh pada biaya operasional, khususnya pada nelayan. Dengan adanya pengunaan mesin yang tingkat konsumsi bahan bakarnya boros atau berlebihan, maka biaya operasional akan semakin melambung atau meningkat. Hal ini akan berpengaruh kepada penghasilan atau pendapatan yang diperoleh nelayan. Oleh karena itu, perlu dilakukan kajian terhadap knalpot mesin yang digunakan nelayan, agar dapat membantu menurunkan tingkat konsumsi bahan bakar. Tujuan yang dari penelitian ini adalah menganalisis tingkat konsumsi bahan bakar minyak terhadap redesain kenalpot perahu pakuira 13 HP. Data dikumpulkan dengan menggunakan metode eksperimental lapangan dengan membandingkan 4 tipe knalpot dengan 5 sekala pengukuran RPM yang berbeda. Lima tingkat RPM tersebut adalah pada RPM 1400, 2150, 2680, 2800, dan 3000. Analisis data yang digunakan adalah analisis statistik parametrik. Hasil yang diperoleh adalah terdapat hubungan dan pengaruh antara RPM dan tingkat konsumsi bahan bakar minyak, dimana semakin tinggi RPM maka tingkat konsumsi bahan bakar akan semakin meningkat dan sebaliknya. Knalpot B merupakan jenis knalpot yang paling baik untuk mengurangi tingkat konsumsi bahan bakar minyak pada tingkat RPM dibawah 2500.

Abstract

The gallium nitride (GaN) films were grown on molybdenum disulfide (MoS2) layers via plasma-assisted molecular beam epitaxy (PA-MBE). The heterostructures of the GaN film were studied using reflection high-energy electron diffraction (RHEED) and HR-XRD. The heterostructures of GaN/MoS2/sapphire were revealed through cross-sectional transmission electron microscopy (TEM). The surface texture of the GaN films was analyzed using FE-SEM. Single-crystal heterostructure GaN films can be obtained on 2D MoS2/c-sapphire. The RHEED demonstrated spot patterns with high intensity showing the single crystal structure constructed in the GaN films. The GaN films on the surface exhibited a hexagonal structure. TEM images taken perpendicular to the surface revealed that, even after 60 minutes of epitaxial growth, the thickness of the GaN films remained consistent at approximately 4 nm. However, the 2D MoS2 layer was not observable in the images due to harm incurred during heteroepitaxial growth. Based on the surface structure, it was found that GaN films were successfully grown on the MoS2 layers using the PA-MBE system.

Abstract

This study presents a comprehensive analysis of the epitaxial growth and surface characteristics of GaN films on 2D MoS2/c-sapphire substrates. Reflection High Energy Electron Diffraction (RHEED) patterns demonstrate the evolution of the substrate and GaN film surfaces during growth. The subsequent growth of GaN films results in the emergence of hexagonal spots, indicative of a single crystal structure. The brightness intensifies with longer growth times, confirming the improvement in GaN crystalline quality. Atomic Force Microscopy (AFM) images provide further insights into the surface texture. The 2D MoS2/c-sapphire substrate exhibits a textured surface, while GaN films display similar features with bright colors corresponding to GaN clusters. The Root Mean Square (RMS) surface roughness values of GaN films have a higher roughness compared to the substrate. Scanning Electron Microscopy (SEM) confirms the uniform coverage of GaN films, revealing smooth growth and organized hexagonal structures. These findings collectively demonstrate the successful epitaxial growth of GaN films on 2D MoS2/c-sapphire substrates, providing valuable insights into their surface morphology and crystalline structure.

Abstract

The increasing usage of plastic is proportional to the amount of plastic waste today. The plastic usage makes the human live easier especially for packaging purposes. However, it also has a negative impact to the environment. This is due to it cannot easily decompose. Therefore, it can reduce the level of soil fertility. Besides plastic, lubricant waste from motor vehicles can induce an environmental problem as well since it is categorized of hazardous material (B3) waste. Currently, the use of plastic waste has been widely carried out by correlating into liquid fuel through thermal cracking or pyrolysis treatment. It produces liquid and it can be used as an alternative liquid fuel. This study uses the co-pyrolysis method for treating the used plastic waste with used lubricants. The composition ratios used are 10:0, 10:2, 10:4, 10:6, and 10:8. The highest acquisition of liquid products was in the composition ratio of 10:6 as much as 24.67% with a calorific value of 11015.33 cal/g. Then the highest calorific, density, and viscosity values were obtained, namely at the 10:8 composition ratio of 11061.67 cal/g, 0.8906 g/mL, and 0.927 cSt. It was concluded that the mixing of used lubricants in the co-pyrolysis of LDPE plastic waste was able to increase the calorific value of the liquid product produced.
