No full textABSTRACT Herwoto, Ilham Putra. dan Aziz, Muhammad Taufiq. 2013. Mesin Poles Spesimen Metalurgi. Tugas Akhir, Program Studi D3 Teknik Mesin, Jurusan Teknik Mesin, Fakultas Teknik, Universitas Negeri Malang. Pembimbing: Drs. Imam Sudjono, M.T Kata Kunci: pemolesan, motor listrik, inverter. Instansi pendidikan banyak yang mengajarkan teori tentang metalografi, salah satunya mereka mengerjakan proses pemolesan dengan alat manual. Hal tersebut dirasa kurang efisien sebab masih banyak menggunakan tenaga manusia, membutuhkan waktu dalam pengerjaan dan hasilnya kurang memadai. Oleh karena itu dirancanglah Mesin Poles Spesimen Metalurgi. Mesin ini menggunakan holder/pemegang benda uji sehingga mengurangi tenaga manusia. Untuk mengatur putaran motor menggunakan inverter sehingga dapat diatur putaran motor sesuai kebutuhan yaitu 0 rpm – 1500 rpm. Kontruksi dari mesin ini dibuat sesederhana mungkin, sehingga dapat menekan biaya pembuatan dan mudah dalam pengoperasiannya. Mesin ini mampu untuk melakukan proses pemolesan sehingga hasil permukaan benda uji halus, bebas goresan, mengkilap, dan menghilangkan ketidakteraturan permukaan benda uji. Mesin ini menggunakan sebuah motor listrik sebagai penggerak, piringan logam, dan sirkulasi air. Sehingga hasil pemolesan menjadi lebih halus, bebas goresan, mengkilap, dan menghilangkan ketidakteraturan permukaan benda uji

KARAKTER GURU IDEAL DALAM BUKU BEGINI SEHARUSNYA MENJADI GURU KARYA FU’AD BIN ABDUL AZIZ ASY-SYALHUB
Get PDFZulkifli. The ideal teacher character in this book should be a teacher by Fu'ad bin Abdul Aziz Asy-Syalhub. The teaching profession cannot be matched by any other profession in virtue and position, and (some) teaching professions are more noble and the more useful the science material being taught, the higher the dignity and degree of its owner. And the most noble knowledge is absolutely the science of syari'at, only then the other sciences, each according to its level. A teacher, if he gives up his deeds for Allah and intends his ta'lim to benefit humans, teach those who are good, and lift the ignorance of them, then that will be a plus for his goodness and a cause for additional rewards, as the Prophet Sallallahu 'alayhi wa sallam in the authentic hadith,
إنَّمَا الأعمَال بالنِّيَّاتِ
Meaning: "Indeed, every practice depends on the intention" (Narrated by Bukhari, no. 1 and Muslim, no. 1907)
The teacher's task is not only limited to delivering subject matter to students, it is even a tough and difficult task, but it will be easy for whom Allah Subhanahu wa ta'ala wants and makes easy. This task requires a teacher to be patient, trustworthy, sincere, and nurturing to those under him, namely his students. May Allah subhanahu wa ta'ala grant us sincerity in our words and deeds, and may Allah Subhanahu wa ta'ala benefit him and the Muslims as well. Only Allah is the Giver of Taufiq, there is no power and strength for us except for His help. Aamii

Analisis Tingkat Kebisingan, Masa Kerja,Shift Kerja Terhadap Stres Kerja Pada Karyawan Di Pt. Bintang Asahi Textile Industri Kab. Sragen
Get PDFThis research aims to know the relationship of the noise level, the work, shift work against work stress on employees at PT. Asahi Star Textile Industry Sragen. This research is quantitative research. The subjects used in this research employees working on the loom as much as 40 respondents out of a total of 60 employees at the loom. Data analysis techniques using multiple linear regression. There is a relationship between noise, working period, Shift work to stress of work. But individually working period there is no relationship with work stress means working period does not affect work stress, while noise and Shift work has a relationship with work stress. Noise, Period work, and Shift work affect work stress then it will also impact the performance of the employees so that their performance will not yield the maximum. Individually working period there is no relationship with work stress because the work has a positive impact against future employees. The noise contributions, working period, Shift work to stress of work amounting to 72%, so there are still some other factors influencing the stress of work
Energy harvesting from tropical biomasses in Wallacea region: scenarios, technologies, and perspectives
Get PDFWallacea attracts much attention from researchers because it is a meeting point between Asia and Australia with rich biodiversity. Therefore, bioenergy source identification in this region is crucial to better understanding biomass potential and utilization. On the other hand, national bioenergy development usually refers to government policies, including granting permits to use forest land, especially on unproductive land. Thus, balanced utilization of tropical forests as an energy source is required. It must consider several aspects comprehensively, including its function in protecting the surrounding landscape, contributing to food security, and creating economic opportunities for communities around forest areas. This paper addresses biomass utilization in the Wallacea region aligned with Indonesian policy targets for bioenergy generation to achieve the net zero emission target by 2060. The study is carried out by limiting the scope of the area and relying on international databases and the nation’s potential targeting biomass research. In addition, the recent development of conversion technologies is adjusted based on available biomass types, including geographic information systems for potential biomass analysis. The analysis and data synchronization are presented in charts, graphs, and tables. In the early section, the potential of biomass in the Wallacea is explained. The following section discusses several scenarios, routes, and utilization technology options for biomass utilization. Various studies that have been conducted are presented in this section, including machine learning adoptions to model and optimize biomass conversion processes. Furthermore, challenges and opportunities are discussed by looking at various factors, such as accessibility, socio-economics, life cycle assessment, and environmental issues.</p
Displacement response of partially precast fly ash polymer concrete on the RC column-pilecap semi-rigid joint connection subjected to cyclic loading
No full textAbstract This study introduces a novel approach to enhancing seismic resilience through the displacement response of partially precast vinyl ester polymer concrete (VEPC) in semi-rigid column-pile cap joint connections under cyclic loading. By comparing VEPC connections of varying joint heights with conventional reinforced concrete (RC), the research highlights the superior performance of VEPC in seismic conditions. The optimized VEPC composition, incorporating vinyl ester resin, catalysts, fly ash, and iron sand, yields a material with significantly higher compressive strength and lower density than traditional concrete. Hysteresis loops from cyclic quasi-static lateral loading tests revealed that VEPC connections exhibited exceptional ductility, achieving greater drift ratios and deflections than RC counterparts. These connections transition seamlessly from elastic to plastic behavior, forming plastic hinges that effectively absorbed seismic energy, minimizing brittle failure and cracking. The optimal joint height balanced strength and ductility, making VEPC ideal for earthquake-prone regions. The low-viscosity VEPC enabled efficient precast construction, streamlining assembly while integrating sustainable fly ash to reduce environmental impact. This innovative semi-rigid system outperformed conventional RC in load-carrying capacity and deformation tolerance, offering a groundbreaking solution for seismic design. By fostering ductile, high-strength joints, VEPC paved the way for performance-based engineering, redefining structural connections to withstand cyclic loads with enhanced resilience. This advancement promises safer, more sustainable infrastructure, revolutionizing design practices in seismically vulnerable areas by prioritizing flexibility and durability
