Abstract

Abstract To help improving the family economic level, the Engineering Physics Team Telkom University held community service program in RW 6 Desa Citeureup Kecamatan Dayeuh Kolot Kabupaten Bandung Propinsi Jawa Barat. The program is supported by Direktorat Jenderal Pendidikan Tinggi, Riset, dan Teknologi Kementerian Pendidikan, Kebudayaan, Riset, dan Teknolog and is continuance of previous Telkom Univeristy’s Community Service Engagement . The participants were the PKK and Karang Taruna members. From 2021 until 2022 we trained them for healthy living and soap production. Even though the program had been suscessful, the product quality, the packaging, and the marketing process have to be improved. Therefore, in 2023, the program is focussing on improving the product quality, packaging, and digital marketing. For that purpose, two consecutive trainings on printed packaging and digital marketing as well as production of new formula soap have been held. Students are also involved in this program via Merdeka Belajar Kampus Merdeka (MBKM). Besides, this program is also supported by the village-owned enterprise (BUMDES) Citeureup. This program is expected to solve the small and medium enterprise challenges in packaging which usually requires large orders above 1000 pieces and enlarge the UMKM target markets. Abstrak Dalam rangka membantu masyarakat meningkatkan ekonomi keluarga, Tim Pengabdian Masyarakat (ABDIMAS) Teknik Fisika Universitas Telkom melaksanakan program ABDIMAS di RW 6 Desa Citeureup Kecamatan Dayeuh Kolot Kabupaten Bandung Propinsi Jawa Barat. Kegiatan ini merupakan kelanjutan dari program Community Service Engagement Universitas Telkom yang sudah dilaksanakan sejak tahun 2021 dalam bentuk pelatihan hidup sehat dan pembuatan sabun. Kegiatan bekerjasama dengan BUMDES Desa Citeureup dan diikuti oleh Kader PKK serta karang taruna. Meskipun kegiatan sudah berhasil membuat dan menjual sabun hingga sekitar 100 L, kualitas sabun, kemasan, dan penjualannya perlu ditingkatkan. Pada tahun 2023 ini Tim ABDIMAS mendapatkan pendanaan dari Direktorat Jenderal Pendidikan Tinggi, Riset, dan Teknologi Kementerian Pendidikan, Kebudayaan, Riset, dan Teknologi dan berfokus pada upaya peningkatan kualitas produk sabun, pembuatan kemasan secara mandiri, dan pemasaran melalui platform digital. Kegiatan juga melibatkan mahasiswa yang mengikuti Program Merdeka Belajar Kampus Merdeka (MBKM). Proses pelatihan pembuatan kemasan dan pemasaran digital telah dilaksanakan. Diharapkan kegiatan ini dapat membantu masyarakat yang selama ini mengalami kendala dalam pencetakan kemasan yang biasanya mensyaratkan minimal pemesanan 1000 eksemplar dan pemasaran produk yang masih terbatas di sekitar Dayeuhkolot.

Abstract

In the wake of the COVID-19 pandemic, the imperative to mitigate pathogen transmission has catalyzed the innovation of soaps imbued with antimicrobial and antibacterial properties. Diverging from conventional reliance on synthetic chemicals, often associated with adverse dermatological reactions, this study explores the formulation of organic liquid soaps. These soaps leverage naturally occurring antibacterial and antimicrobial compounds from readily accessible plants, presenting a viable alternative to commercially available inorganic body washes predominantly manufactured by small to medium-sized enterprises. Specifically, this research harnesses papaya and aloe vera extracts for their antimicrobial attributes, augmented with turmeric and piper betel for enhanced antibacterial efficacy. Despite the recognized potency of turmeric and piper betel, variability in their effectiveness necessitates rigorous validation against the Indonesian National Standards (SNI) to ensure product quality and safety. This includes comprehensive evaluations of pH levels, density, Total Plate Count (TPC), and Mold and Yeast Count (MYC) to certify the soap's inhibitory capacity against bacterial and fungal proliferation. Employing maceration and hot processing techniques, the formulated papaya-based soap adhered to SNI 4085:2017 criteria for pH and MYC, although initially failing the TPC test. Subsequent incorporation of turmeric extract facilitated compliance with all SNI benchmarks. Conversely, aloe vera formulations only satisfied pH requirements under the SNI, even after adding piper betel. However, substituting piper betel with turmeric extract enabled the aloe vera soap to fulfill the requisite SNI parameters. These findings underscore turmeric extract's superior antibacterial properties, positioning it as a pivotal component in papaya and aloe vera soap formulations. Contrary to prevalent assumptions regarding piper betel's antimicrobial and antibacterial effectiveness, our investigation substantiates turmeric's superior role in bacterial growth inhibition within organic soap matrices.

Abstract

This research is aimed to analyze and simulate the temperature distribution in heat sink CPU processor. The study analyzes the heat absorption from the heat source to the bottom of the heat sink, the conduction process, and the forced convection process. All processes are simulated with software Comsol Multiphysics 4.4 to obtain the optimal heat sink design. The simulation is performed by varying the number of fins, the fin thickness, the air gap between two fins, the fin surface area, and the convection coefficient. The optimal design is found for heat sink with 40 pieces fins, fin thickness of 0.4 mm, air gap of 2.4 mm, fin surface area of 9425 mm2, and the convection coefficient of 5.26 W/m2K. Further simulation shows that PID control improved the forced convection process. A proportional control (P) is reasonable enough to achieve a settled convection process. A settling temperature occurs at 241 s after heat is applied to the system. This is faster than non-controlled convection process which requires 1600 s instead. Additional integration and derivative controls will increase stability at later time.

Abstract

Masalah sampah sudah menjadipermasalahan yang harus diselesaikan setiap negaraberkembang. Masalah sampah juga akan menjadi tolok ukurbagi perkembangan suatu negara. Masalah sampah sendirisudah diatur dalam Undang- Undang Republik Indonesianomor 18 tahun 2008 tentang Pengelolaan Sampah. DalamUndang-Undang tersebut disebutkan pengertian pengelolaansampah adalah kegiatan yang sistematis, menyeluruh,berkesinambungan yang meliputi pengurangan danpenanganan sampah. Menurut data yang didapat dari websiteSistem Informasi Pengelolaan Sampah Nasional (SIPSN) datatimbulan sampah yang dihasilkan tahun 2020 sebanyak 33 tondengan komposisi sampah sisa makanan sebanyak 38,9%.Dalam pengelolaan sampah ada berbagai metode yang dapatdilakukan, salah satu metode yang sekarang banyak yangdigunakan dengan menggunakan larva Black Soldier Fly(BSF). Serangga Black Soldier Fly (BSF) memiliki nama latinHermetia Illucens dan salah satu jenis serangga yang dapathidup di musim tropis. Pada penelitian didapat hasilpengolahan sampah dengan menggunakan black soldier fly(BSF) hasil yang paling baik pada sampah sisa makanandapat 80% penguraian yang dilakukan. Sampah sisamakanan lebih mudah terurai dengan perbandingan sampahsayur 28% dan sampah buah 36%.Kata kunci—sampah, pengolahan sampah, black soldierfly

Abstract

The concepts of floating, flying, and sinking object have been studied since junior high school. However, we still often find students' misconceptions regarding the concept, especially of flying objects, even at the university level. This work aims to propose a clarification of the concept of a flying object in the fluid to be correctly described the condition for the flying object. We used eggs, water, and salt solutions to demonstrate sinking, rising, and floating objects in the fluids. The results showed that when the density of the object is the same as the density of the fluid, the position of the object is still at the bottom of the fluid since it was not flying in the middle of the depth of the fluid. But the object does not touch the bottom of the container so that the object's height is zero. This is because the object has not had a driving force (Fd = 0) that pushes the object upward towards the surface of the fluid to float. When the density of the fluid slightly exceeds the density of the object, the object immediately moves upward to the fluid surface - floating phenomenon is started. The greater the difference between the density of the fluid and the density of the object, the faster the object moves towards the surface. The object cannot stay at any position between the bottom and the surface of the fluid. A stable position is reached when the object reaches the surface of the fluid to float. This work is expected to increase students' understanding of flying objects in fluids.
