Abstract

Salah satu penyebab fraktur pada tulang ialah kecelakan pada saat beraktifitas maupun berkendara. Penggunaan pelat implan metatarsophalangeal (MTP) menjadi satu dari berbagai macam metode penanganan fraktur pada tulang. Maka penting untuk mengetahui kemampuan pelat implan dalam menahan segala jenis pembebanan yang mungkin terjadi saat digunakan di tubuh manusia. metode yang digunakan untuk menganalisis kekuatan struktur pelat implan MTP ini adalah dengan menggunakan finite element method. Terdapat tiga tahapan dalam metode ini. Tahapan pertama adalah preprocessing, jenis material dan jenis meshing ditentukan pada tahapan ini. Lalu tahap solution, yaitu penentuan jenis pembebanan dan constraint  yang digunakan. Terakhir tahapan post processing, yaitu proses analisis hasil simulasi yang dilakukan pada dua tahapan sebelumnya. Pada penelitian ini didapatkan nilai von-mises stress dengan pembebanan 44.228 N hingga 200 N sebesar 51.492 MPa hingga 232.85 MPa. Nilai tersebut masih berada di bawah nilai tegangan luluh material Ti-6Al-4V yakni sebesar 880 MPa. Nilai von-mises stress yang rendah tersebut mengakibatkan deformasi total dan deformasi sumbu Z yang terjadi cukup rendah, rata-rata pada angka 0.0189 mm dan 8,77x10-4 mm. Berdasarkan perolehan nilai tersebut dapat disimpulkan pelat implan MTP dengan material Ti-6Al-4V tidak terjadi deformasi plastis. Deformasi yang terjadi pada  pelat implan MTP adalah deformasi elastis, dengan nilai yang cukup rendah. Sehingga aman digunakan sebagai salah satu alat bantu dalam proses penyembuhan fraktur pada tulang MTP.

Abstract

There are 10 countries with the least pollutant levels in the world. This is what triggers the example of other countries. So it is necessary to explore what makes these countries superiors in environmental issues so that they are ranked in the top 10 on the world scales according to the U-Earth Team. However, a clean country can be due to a small area or a small population so that the pollutants become small. The method used for this research is a literature study with a qualitative research type based on what already exists. What is meant here is the research method with reference to the existing literature. The stages of this research are looking for problems, then collecting the existing literature. Then after that, examine the related parameters related to the problem. The final step are to find a solution to the existing problem. The importance of progress of going green in this great country so that it can save much human beings. You could say, in terms of SO2, NOx and Dust emission levels in Indonesia, Indonesia has a fairly high ratio, so it is important to check CO2 in every vehicle and industry as well as limit personal use. The essence of this research is that public education about go green energy and minimizing pollution is very much needed.

Abstract

This article features experimental findings on the tensile testing procedure conducted on package seals made from Polyethylene Terephthalate (PET)-Low-Density Polyethylene (LDPE)-Aluminum Foil composite materials commonly employed in food packaging applications. This study aims to ascertain the outcomes of the tensile test or tensile strength of the packaging seal utilizing the Auto Tensile Tester XLW according to the ASTM F88 standards. The tensile test involves using two types of variables: independent variables and dependent variables. The study used temperature (°C) and holding time (s) as independent factors, whereas the dependent variable is the tensile test results or tensile strength (N/mm2). This study utilized identical parameters for each variable. The specimen's measurements were 15mm x 25mm. This experiment included three temperature factors and a constant holding time of 1 second. Every parameter underwent four tests, resulting in twelve test samples. Based on the findings, the optimal temperature range for achieving the most efficient packing sealing was 135oC. The maximum sealing strength of 17.50 N/mm2 was attained within this temperature range, and the outcomes were influenced by both the temperature and the duration of the holding period. Each sample has distinct values, encompassing a rather narrow range.

Abstract

Desa Kedung Jeruk terletak di RT/RW 4/1 Dosun Krajan Desa Kedungjeruk Kecamatan Cibuaya Kabupaten Karawang, memiliki sumber daya para pemuda yang kuat dan memupuni didalam dunia kerja. Pada umumnya masyarakat tersebut berprofesi sebagai petani. Tetapi para pemuda menginginkan pekerjaan yang dapat mengembangkan UMKM di Desa tersebut. Di Desa tersebut memiliki usaha mebel untuk kebutuhan rumah tangga. Kegiatan produksi mebel memiliki pengaruh pesat untuk perkembangan UMKM didesa.Namun karena tidak banyak keahlian dalam memilih material kayu mebel serta keahlian membuat mebel maka para pengabdi memberikan pelatihan untuk mengatasi permasalahan tersebut, dengan dimulai memberikan sosialisasi, pengarahan pembuatan mebel dan pemilihan jenis kayu, proses produksi mebel dan memberika kuisioner tentang kepuasan pada pelatihan tersebut. Peserta masyarakat Kedungjeruk mengikuti pelatihan sebanyak 8 orang dengan memberikan responden yaitu ingin menerapkan ilmu tentang pembuatan mebel, ingin pelatihan mebel dilanjutkan dan mengadakan pelatihan skill lainnya. Dengan responden tersebut memberikan dampak bagi masyarakat yang antusias mengikuti pelatihan untuk meningkatkan skill tersebut

Abstract

Catalytic converters (CCs) play a critical role in reducing exhaust emissions in motor vehicles. This study presents a sustainable solution by utilizing rice husk waste (RHW) to produce activated carbon, which is then fabricated into honeycomb-shaped catalytic converters with thickness variations of 10 mm, 15 mm, 20 mm, and 25 mm. Among these, the 15 mm-thick converter (CC15) exhibited the most effective emission reduction performance, achieving reductions of 78.33% in hydrocarbons (HC) and 48.23% in carbon monoxide (CO). To assess its impact on engine performance, a series of dynamometer tests were conducted, showing that the installation of CC15 led to less than a 6% decrease in both power and torque, which is considered acceptable for daily vehicle use. Furthermore, the air–fuel ratio (AFR) shifted from an average of 13.38 under standard conditions to 14.19 with CC15, indicating stable combustion. Acoustic evaluation also confirmed that the CC did not function as a noise suppressor, resulting in no significant alteration to engine acoustics. Overall, the CC15 demonstrates an effective balance between environmental performance and engine efficiency, offering a practical emission control solution based on locally sourced agricultural waste.
