Development of Applications for Simplification of Boolean Functions using Quine-McCluskey Method

Purpose: This research makes an application to simplify the Boolean function using Quine-McCluskey, because length of the Boolean function complicates the digital circuit, so that it can be simplified by finding other functions that are equivalent and more efficient, making digital circuits easier, and less cost.Design/methodology/approach: The canonical form is Sum-of-Product/Product-of-Sum and is in the form of a file, while the output is in the form of a raw and in the form of a file. Applications can receive the same minterm/maksterm input and do not have to be sequential. The method has been applied by Idempoten, Petrick, Selection Sort, and classification, so that simplification is maximized.Findings/result: As a result, the application can simplify more optimally than previous studies, can receive the same minterm/maksterm input, Product-of-Sum canonical form, and has been verified by simplifying and calculating manually.Originality/value/state of the art: Research that applies the petrick method to applications combined with being able to receive the same minterm/maksterm input has never been done before. The calculation is only up to the intermediate stage of the Quine-McCluskey method or has not been able to receive the same minterm/maksterm input

Pengaruh jumlah nozzle terhadap kinerja turbin pelton sebagai pembangkit listrik di Desa Sumber Agung Kecamatan Suoh Kabupaten Lampung Barat

A micro hydro power plant, or commonly known as a turbine is a power plant that utilizes the potential energy of water to be converted into mechanical energy which is then converted into electrical energy using a generator.

PREGLED HAZARDA PROUZROČENOGA SLIJEGANJEM POVRŠINE U DELTI PEKALONGAN, SREDIŠNJA JAVA: UVID IZ PODZEMLJA

Land subsidence is a global threat to coastal areas worldwide, including the North Java coastal area. Of many areas experiencing land subsidence in North Java, the rate of land subsidence in Pekalongan has matched the high subsidence rates usually found in big cities. The rate of land subsidence in Pekalongan far exceeds the sea-level rise, resulting in a looming threat of land loss. The devastating impacts of land subsidence are the manifestation of its subsurface movement. Therefore, it is essential to understand the subsurface to elucidate the mechanism of land subsidence. Previous studies on land subsidence in Pekalongan are mainly related to subsidence rate monitoring and have not elaborated on the subsurface condition. This paper reviews the Pekalongan subsurface geology based on available literature to provide insight into the land subsidence problem. The results revealed that the land subsidence occurs in the recent alluvial plain of Pekalongan, consisting of a 30-70 m thick compressible deposit. Possible mechanisms of land subsidence arise from natural compaction, over-exploitation of confined groundwater, and increased built areas. As the seismicity of the study area is low, tectonic influence on land subsidence is considered negligible. It is expected that the offshore, nearshore, and swamp deposits are still naturally compacting. As the surface water supply is minimal, over-exploitation of groundwater resources from the deltaic and Damar Formation aquifers occurs. In the end, future research direction is proposed to reduce the impacts of the subsidence hazard.Slijeganje površine tla prijetnja je svim obalnim područjima, pa tako i obali sjeverne Jave. Niz područja u tome prostoru podložno je takvu slijeganju. Iznos toga spuštanja posebno je izražen u velikim gradovima područja Pekalongan. Taj iznos daleko nadilazi porast morske razine rezultirajući gubitkom kopna. Vrlo velik učinak takvih površinskih spuštanja odražava se također i u dubini. Zato je nužno razumjeti ispodpovršinske pojave kako bi se objasnilo samo spuštanje površine. Prethodna istraživanja tih pojava u Pekalonganu uglavnom su bila usmjerena na praćenje iznosa spuštanja, bez uvida u dubinske odnose. Ovdje je prikazana dubinska geologija istraživanoga područja, pregledom dostupne literature. Rezultati su pokazali kako se spuštanje događa u recentnoj aluvijalnoj ravnici Pekalongana, koja obuhvaća tlo debljine 30 – 70 m. Jedan od mogućih uzroka spuštanja jest prirodno zbijanje, zatim pretjerana eksploatacija podzemnih voda te prevelika izgrađenost. Seizmičnost je prostora mala, stoga je i utjecaj tektonike na taj proces zanemariv. Nadalje, morski, priobalni i močvarni talozi podložni su recentnom, prirodnom zbijanju. Kako je pritok svježe, meteorske vode minimalan, dolazi do pretjerane eksploatacije vodonosnika formacije Damar u delti. Predložena su buduća tematska istraživanja kojima bi se smanjio utjecaj opasnosti proizišlih iz slijeganja

PROFIL KADAR C-Reactive Protein (CRP), Rheumatoid Factor (RF) DAN LIMFOSIT SEBAGAI INDIKATOR RESPON IMUNITAS PADA LANSIA

C-Reactive Protein (CRP) is an acute phase protein that is present in normal serum in very small amounts. There are many factors that can affect CRP levels including age, gender, and smoking status. Increasing age allows the emergence of several groups of rheumatic diseases. One of the rheumatism groups that often accompanies the elderly is Rheumatoid Arthritis (RA). Elderly is an age that has a greater chance of experiencing autoimmunity. RA sufferers in the elderly around the world have reached 355 million people, meaning that 1 in 6 elderly people in the world suffer from rheumatism. The resulting human immune response depends on lymphocytes, where systemic inflammation significantly suppresses cellular immunity. Based on the Central Java Health Profile (2019) it shows that the number of elderly people in Cilacap Regency is 174,143 people. This study aims to analyze the number of lymphocytes as an indicator of the immune response in the elderly against levels of CRP, RF. The method used is descriptive qualitative method. From the results of a study of 30 samples in residents of RW 03, Donan Cilacap Village, the results of qualitative examination of CRP and RF levels showed normal results (100%), and the lymphocyte count results obtained for a number of 12 samples showed low results.C-Reactive Protein (CRP) merupakan protein fase akut yang terdapat dalam serum normal dalam jumlah yang sangat sedikit. Ada banyak faktor yang dapat mempengaruhi kadar CRP termasuk usia, jenis kelamin dan status merokok. Bertambahnya usia memungkinkan munculnya beberapa kelompok penyakit rematik. Salah satu golongan rematik yang sering menyertai lansia adalah Rheumatoid Arthritis (RA). Lansia adalah usia yang memiliki peluang lebih besar untuk mengalami autoimun. Penderita RA pada lansia di seluruh dunia telah mencapai 355 juta orang, artinya 1 dari 6 lansia di dunia menderita rematik. Respon imun manusia yang diakibatkan bergantung pada limfosit, dimana inflamasi yang sistemik secara signifikan menekan imunitas seluler. Berdasarkan Profil Kesehatan Jawa Tengah (2019) menunjukkan bahwa jumlah lansia di Kabupaten Cilacap 174.143 jiwa. Penelitian ini bertujuan untuk menganalisis jumlah limfosit sebagai indikator respon imunitas pada lansia terhadap kadar CRP, RF. Metode yang digunakan adalah metode deskriptif kualitatif. Dari hasil penelitian terhadap 30 sampel pada warga RW 03 Kelurahan Donan Cilacap diperoleh hasil pemeriksaan kadar CRP dan RF secara kualitatif menunjukan hasil normal (100%), dan hasil jumlah limfosit diperoleh sejumlah 12 sampel menunjukkan hasil rendah
