Pedagang di pasar bunga wangaya melakukan pekerjaannya dengan sikap kerja duduk statis. Sikap ini dilakukan selama 10 jam setiap harinya mulai pukul 11.00 – 21.00 WITA. Durasi bekerja tersebut merupakan durasi yang melebihi waktu normal. Ketika statis maka otot-otot punggung akan terbebani. Apabila terus menerus berlebihan, dapat memicu timbulnya keluhan musculoskeletal. Penelitian menggunakan ...

This research aims to identify students' understanding of physics concepts in the topic static fluids and analyze which subtopics often pose a problem. study is quantitative descriptive using an instrument 8 three-tier questions on Hydrostatic Pressure, Pascal's Law, Archimedes' Principle. The subjects consisted 35 students from grade XI St. Albertus Malang Catholic High School who have studied...

In recent years, fuzzy logic has been increasingly used to improve conventional methods. This paper proposes fuzzy-logic based improvements to the n-tuple recognizer algorithm. The original n-tuple method works by matching bunches of n pixels exactly between the test images and the template images. In the proposed method, new concepts such as ‘Importance of Tuple’ and ‘Degree of Match’ of a tup...

One may not be able to measure exactly the various parameters involved in computing physical fitness and cardiovascular efficiency of a human being. Inexactness, in turn, may lead to inaccurate results and misleading conclusions. In the present paper, using fuzzy arithmetic, we modify both the Long Form and in Short Form approach associated with the Harvard Step Test, under fuzzy environment. T...

Fuzzy modeling of high-dimensional systems is a challenging topic. This paper proposes an effective approach to data-based fuzzy modeling of high-dimensional systems. An initial fuzzy rule system is generated based on the conclusion that optimal fuzzy rules cover extrema [8]. Redundant rules are removed based on a fuzzy similarity measure. Then, the structure and parameters of the fuzzy system ...

Water pressure tests are a common method of soil exploration in engineering geology. The classification of water pressure test results is usually carried out by expert geologists. This paper presents a method for the automatic classification of water pressure test curves. After discussing the features extracted from the test curves the fuzzy rule base used for classification is described. Some ...

This paper presents a fuzzy extension of the simple assembly line balancing problem of type 2 (SALBP-2) with fuzzy job processing times since uncertainty, variability, and imprecision are often occurred in real-world production systems. The jobs processing times are formulated by triangular fuzzy membership functions. The total fuzzy cost function is formulated as the weighted-sum of two bi-cri...

Pemikiran yang sama atau pemberian solusi persis ketika dinyatakan oleh beberapa siswa pada pertanyaan terbuka bersifat High Order Thinking Skill (HOTS) mengindikasikan kurangnya kepercayaan diri (self-efficacy) mereka. Hal tersebut melatarbelakangi tujuan dari penelitian ini untuk mengukur self-efficacy melalui Lembar Kerja Siswa (LKPD) berbasis tinjauan empiris dan teoretis materi fluida stat...

An adaptive method to construct compact fuzzy systems for solving pattern classiication problems is presented. The method consists of two phases: a rule identiication phase and a rule selection phase. The rule identiication phase generates fuzzy rules from numerical data through a simple fuzzy grid method, then tunes the resulting fuzzy rules by training a neuro-fuzzy network used to model the ...
