Abstract

The definition of mining and quarrying is constructed as an activity that includes research, management, and exploitation. Sand mining is part of non-metal mining business activities that aim to produce its associated minerals. This study aims to determine the results of the evaluation of the feasibility of heavy equipment investment in Excavators based on calculations using the NPV (Net Present Value), IRR (Internal Rate of Return), BEP (Break Event Point) and PP (Payback Period). This research was conducted surveys, observations and interviews to obtain data. The results of this study Investment in the procurement of heavy equipment Excavator is feasible to run because the Net Present Value (NPV) value is positive (+) which means it is good and acceptable while the resulting NPV value is Rp1,944,640,086.47. Then analyze the calculation of the feasibility of the Internal Rate of Return (IRR) obtained 26%. Thus IRR> MARR = 26%> 15.5% or according to the calculation of IRR this investment is RIGHT to run. Furthermore, from the analysis of the calculation of the Break Even Point (BEP), the calculation results obtained are 5.2153 years or BEP occurs when the break-even point occurs when PM - PK = Rp 5.006.705.873. In the Payback Period (PP) research, the investment turning point occurred in year 5.6856 at a value of Rp 4.009.690.743,31. It can be interpreted that for investment within a period of 10 years is FAIR.

Abstract

SMK PGRI 35 Solokan Jeruk Kabupaten Bandung is an educational institution under the auspices of the Trustees of the Association of Indonesian Teachers' Educational Institutions (YPLP PGRI) with the guidance of YPLP PGRI West Java Province. The design of the Tracer Study information system is a system created to trace alumni (Tracer Study) at SMK PGRI 35 because there is no information that can support adding accreditation value, how long the waiting period for graduates to get a job, how relevant the curriculum of the field of study is to type of work, position placement, location, and work situation. Therefore, a website-based Tracer Study information system is needed, namely using the system development method approach used is Object Oriented Analysis and Design (OOAD) while the model used is Rational Unified Process (RUP) with a development tool, namely Unified Modeling Language (UML). The results showed that this program makes it easier for schools to manage alumni data and makes it easier for schools to track alumni data so that it can support the addition of accreditation scores, how long the waiting period for graduates to get a job, how relevant the field of study is to the type of work, position placement, location, and job situation.

Abstract

Kesehatan dan keselamatan kerja berperanpenting dalam menjaga produktivitas dan kesejahteraanpekerja, termasuk di sektor jasa coffee shop. Penerapanergonomi diperlukan untuk meningkatkan kenyamanan kerja,khususnya bagi barista yang melakukan aktivitas berulangdengan postur tidak ergonomis yang berpotensi menimbulkanMusculoskeletal Disorders (MSDs). Penelitian ini bertujuanmengidentifikasi faktor risiko MSDs, mengevaluasi tingkatrisiko postur kerja, serta memberikan rekomendasi perbaikanfasilitas kerja berbasis ergonomi. Penelitian dilakukan di Tel-UCoffee Purwokerto dengan objek aktivits kerja barista dansubjek enam orang barista. Metode yang digunakan meliputiobservasi, pengukuran antropometri, Nordic Body Map (NBM),dan Rapid Upper Limb Assessment (RULA). Hasil analisismenunjukkan beberapa aktivitas, seperti penggunaan mesinespresso, pengambilan es batu, dan pengemasan cup, memilikitingkat risiko tinggi (skor level 4). Solusi dari penelitian denganmerancang dua meja kerja ergonomis yang disesuaikan denganpersentil data antropometri barista. Berdasarkan dataantropometri, dirancang meja kerja ergonomis dilengkapi boxes untuk mengurangi postur membungkuk. Hasil validasimenunjukkan bahwa desain dapat meningkatkan kenyamanankerja dan menurunkan keluhan fisik. Kesimpulan penelitianmemastikan bahwa penerapan prinsip ergonomi dapatmeminimalkan risiko MSDs dan meningkatkan produktivitasbarista. Penelitian ini diharapkan menjadi acuan perbaikanfasilitas kerja pada sektor usaha serupa.Kata kunci — Barista, Postur Kerja, Ergonomi, NBM,RULA, Antropometri

Abstract

This study aims to analyze the influence of Islamic spirituality on teaching professionalism among students of the Islamic Religious Education Study Program at the Ahmad Dahlan Institute of Probolinggo. The research employs a quantitative approach with an explanatory research design to examine the relationship between Islamic spirituality as the independent variable and teaching professionalism as the dependent variable. The population consists of all students of the Islamic Religious Education Study Program. The sampling technique used is probability sampling through the simple random sampling method. Data collection is conducted using a questionnaire developed based on indicators of Islamic spirituality and teaching professionalism, measured using a Likert scale. The collected data are analyzed using descriptive statistical analysis and simple linear regression to test the research hypothesis. The results show that Islamic spirituality has a positive and significant influence on students’ teaching professionalism. Students with higher levels of spirituality tend to demonstrate stronger commitment to academic responsibilities, greater awareness of professional ethics, and higher readiness to develop pedagogical competencies. These findings indicate that Islamic spirituality functions not only as a personal religious dimension but also as a moral and motivational foundation in shaping the professionalism of prospective educators. Therefore, strengthening spiritual values in higher education, particularly within the Islamic Religious Education Study Program, is essential to develop professional teachers with integrity and strong Islamic character.
