PENERAPAN MODEL LANCHESTER PADA PERTEMPURAN IWO JIMA

Dalam skripsi ini dibahas penurunan model Lanchester dan penerapannya pada pertempuran Iwo Jima. Model tersebut diselesaikan menggunakan metode variasi parameter, diaproksimasi menggunakan konsep jumlah Riemann dan kemudian dibandingkan dengan data empiris. Hasil-hasil yang diperoleh menunjukkan bahwa model Lanchester cukup akurat dalam memprediksi jumlah pasukan Amerika yang aktif bertempur di medan pertempuran tiap harinya. Kata Kunci: model Lanchester, metode variasi parameter, jumlah Riemann, pertempuran Iwo Jima

Automatic Sprayer Controller Untuk Airlock Chamber RSUP Dr. M. Djamil Padang

Penyebaran COVID-19 telah melanda dunia hingga mencapai Indonesia, khususnya wilayah sumatera barat. RSUP  Dr. M Jamil padang merupakan salah satu rumah sakit yang menjadi tempat perawatan pasien COVID-19. Dengan segala keterbatasa peralatan RSUP menangani pasien yang dirawat di sana. Salah satu masalah yang dihadapi adalah kurang maksimalnya alat yang berfungsi untuk mensterilkan udara antara ruang isolasi dan pintu keluar ruang tersebut dimana ruang ini disebut airlock chamber. Airlock Chamber adalah ruang kosong yang berada diantara ruang isolasi dengan pintu masuk ruang isolasi yang berguna untuk menjaga agar udara dari ruang isolasi tidak keluar ke ruang bebas. Politeknik Negeri Padang (PNP) berusaha melakukan inovasi berdasarkan teknologi terapan dengan memanfaatkan staf pengajar yang kompeten dan mahasiswanya merakit pompa air, selang dan nozzle pengembun dipadukan dengan modul sensor proximity dan driver relay untuk mengendalikan pompa maka dibuatlah Automatic Sprayer Controller yang dapat melakukan penyemrotan secara otomatis setelah tenaga medis atau pasien keluar dari ruang tersebut. Pihak RSUP Dr. M. Djamil Padang bersyukur dan berterima kasih sekaligus memberikan apresiasi kepada PNP karena bukan hanya merancang dan membuat Automatic Sprayer Controller tapi terjun langsung melakukan instalasi dalam chambernya. Selain itu RSUP  Dr. M. Djamil Padang berharap kerjasama yang berkesinambunagn dengan PNP tetap terjalin dalam inovasi teknologi tepat guna khususnya di bidang medis yang terbukti saat ini membantu menekan pandemii Covid-1

Sustainable Drainage System Analysis In The Institut Teknologi Sumatera (ITERA)

The Institut Teknologi Sumatera is a new university that still requires planning and infrastructure development, one of the development needed is the construction of a drainage system, namely a sustainable drainage system that adheres to the concept of water conservation. The purpose of this research is to analyze topographic conditions, as well as the performance of the existing drainage system in ITERA and to develop recommendations for a sustainable drainage system. In this study, several stages were carried out, first analyzing the topographical conditions in ITERA. The second is to analyze the existing drainage capacity, which is to compare the existing drainage capacity to the runoff that occurs when it rains. The calculation of runoff discharge is obtained from hydrological analysis of rainfall data using the annual maximum partial series method. Third, synthesizing the connectivity between drainage segments to the reservoirs in ITERA.   The results of several analyzes above show that, firstly, the topography in ITERA is relatively flat with the most dominant elevations being 85 - 100 m and 100 - 105 m. Second, the calculation results show that the existing drainage capacity is still able to accommodate the runoff that occurs. So for now it is still safe against inundation and flooding. Third, the results show that there are several existing drainages that have not been connected to other drainage segments and water does not run off to the designated place as a reservoir, namely the reservoir.   &nbsp

WHY DID ALL FAMILY MEMBERS ABANDON THIS MAN?

Danas je alkoholizam treća bolest suvremenog čovječanstva, u Hrvatskoj ima 6% ovisnika o alkoholu, a oko 15% muškaraca starijih od 20 godina prekomjerno uzima alkoholna pića. Prikazan je 65-godišnji pacijent, mjesec dana u mirovini, s teškim, neliječenim mnogostrukim psihičkim, fizičkim i socijalnim problemima uzrokovanim alkoholom. Tjelesne posljedice su često ozljeđivanje, prijelomi nadlaktice i kuka. Psihosocijalne posljedice su gubitak obiteljske kuće, odvojen život od žene koja živi povremeno kod kćerke, sin je razveden, često hospitaliziran na psihijatriji zbog PTSP-a i nije voljan primiti oca, troje unučadi od kojih su dvoje krenula „krivim“ putem i smješteni su u učenički dom, a unuka od 17 godina odustala je od škole. Njegov brat, sa senzomotornom afazijom nakon moždanog udara ga također ne može primiti u prigradsku kuću, koju iznajmljuje. Pacijent je prošlog ljeta zapušten spavao ispred ambulante te je uz insistiranje liječnika i prisilno hospitaliziran, zadržan „iz socijalnih razloga“ petnaestak dana na psihijatrijskom odjelu i potom udomljen. Obiteljska medicina je idealna za liječenje poremećaja uzrokovanih alkoholom i barem jednako efikasna kao specijalizirana zdravstvena skrb. Još uvijek je prisutna stigmatizacija alkoholičara i posljedična društvena diskriminacija, što valja suzbijati antistigma programima.Alcoholism is a major public health problem in modern society. There is 6% of alcoholics in Croatia while 15% of adult men drink excessively. A patient, 65-year-old alcoholic with severe, untreated multiple mental, physical and social problems is presented. Injuries such as fractures of upper arm and hip were frequent physical consequences. He lost his family home, separated from his wife, his son is divorced, frequently hospitalized for PTSD, and is not willing to accept his father to live with him. Three of his grandchildren undertook the wrong way in their lives (two of them were institutionalized, and a 17-year-old granddaughter abandoned school). His brother, with sensomotor aphasia after a stroke, refused to accept him in his suburban house, which is currently rented. Last summer the patient was found asleep in front of the dispensery in a poor condition, and compulsorily hospitalized. After he spent 15 days in a psychiatric ward for “social reasons” the patient was placed in foster care. Family medicine is ideal for the management of alcoholism. Interventions in reduction/cessation of heavy drinking in primary care are as effective as in specialized institutions. Stigmatization and consequential social discrimination of alcoholics is still present what is the reason for family doctors to implement antistigmatic programs
