Abstract

System of temperature control are used in many facility such as room temperature control, quality control of food and drink, electronic equipment control and etc. control of temperature can be done by using microcontroller as a media processing and process the changes of temperature that occured to the voltage. One of supporting component on the microcontroller to detect the change of temperature is temperature sensor LM 35 which in this study we will focus on the temperature sensor LM 35 for detect of change of temperature on the sea water in a small scale. the purpose of this study is to determine the ability and performance of temperatur sensor LM 35 for detect the changes of temperature sea water and check the condition of temperatur sensor LM 35 in use on the sea water. The results show that the temperature sensor of LM 35 can be used to measure the changes of temperatur sea water without have higher difference on the actual value and experiment results. the range of difference is smaller and the temperature sensor of LM 35 can be used to measured the change of temperature of sea water.Keywords: LM 35 Sensor, Microcontroller ATmega 8535, Sea Water Temperature

Abstract

Teknologi pengenal suara (speech recognition) merupakan teknologi yang berkembang pesat dalam bidang kecerdasan buatan (artificial intelligent). Saat ini, teknologi pengenal suara menjadi hal yang komersil melalui berbagai media teknologi seperti smartphone dan komputer. Salah satu pembentuk struktur pengenal suara agar dapat bekerja pada perangkat tersebut adalah model statistik pengenal suara Hidden Markov Model (HMM). Penerapan HMM pada berbagai kasus menunjukkan bahwa model ini cocok dengan berbagai macam data. Tulisan ini merupakan sebuah tinjauan untuk model HMM yang bertujuan untuk memberikan gambaran dan pemahaman terhadap kinerja HMM melalui rangkuman sejumlah penelitian yang digunakan dalam berbagai data. Penerapan HMM tersebut menunjukkan optimalisasi kinerja HMM dan tinjauan terhadap sejumlah penelitian menunjukkan bahwa tingkat keberhasilan HMM dalam mengenali data mencapai 71.43%.

Abstract

Proses persalinan ibu yang sangat dikenal saat ini adalah proses normal dan proses operasi (caesar), begitu juga di bidan Hj.Ponirah. Untuk melalui proses persalinan ini mulai dari awal kehamilan sampai dengan mendekati proses persalinan, ibu harus selalu memeriksakan kehamilannya kepada dokter ataupun bidan. Ada beberapa faktor yang mempengaruhi proses persalinan ibu yaitu posisi bayi, berat badan bayi serta kesanggupan ibu untuk proses persalinan. Metode Simple Additive Weight (SAW) ini dipilih karena metode ini menentukan nilai bobot untuk setiap atribut yang berpengaruh pada proses persalinan ibu, kemudian dilanjutkan dengan proses perangkingan yang akan menyeleksi alternatif terbaik dari sejumlah alternatif, dalam hal ini alternatif yang dimaksud adalah proses persalinan ibu normal atau operasi (caesar) berdasarkan kriteria-kriteria (faktor) yang ditentukan. Dengan metode perangkingan tersebut, diharapkan penilaian akan lebih tepat karena didasarkan pada nilai kriteria dan bobot yang sudah ditentukan sehingga akan mendapatkan hasil yang lebih akurat terhadap bagaimana proses persalinan ibu.

Abstract

Background: The literature on peripheral inflammatory cytokine levels in Parkinson's disease (PD) reveals a multifaceted relationship between immune responses and disease pathology. Early foundational work emphasized the crucial roles of both central and peripheral inflammation in PD progression, positing that immune dysregulation may precede neurodegeneration (Su & J. Federoff, 2014). This perspective is supported by subsequent studies that delve into the role of α-synuclein in sustaining neuroinflammation, highlighting the dual nature of inflammatory processes that can initially appear beneficial yet ultimately lead to neuronal degeneration (Pessoa Rocha et al., 2015). Literature Review: Recent research has further established a correlation between elevated levels of peripheral inflammatory cytokines and the severity of motor symptoms in PD, suggesting that inflammation is not merely a byproduct of the disease but a significant contributor to its clinical manifestations (Diaz et al., 2022). Historical analyses have documented the presence of activated microglia and elevated cytokines in PD patients, linking these findings to the progression of motor symptoms (Heidari et al., 2022). The systemic nature of inflammation in PD has been underscored by studies that connect peripheral immune responses to central neuroinflammatory processes, indicating that PD affects various bodily systems (P. Williams et al., 2022). Moreover, the exploration of biomarkers of inflammation in both blood and cerebrospinal fluid (CSF) has illuminated the role of microglial activation and cytokine release in PD progression (Zimmermann & Brockmann, 2022).. Conclusion: In conclusion, the body of literature underscores the significance of peripheral inflammatory cytokines in the pathophysiology of PD. The interplay between central and peripheral immune responses is critical in understanding the disease's progression and symptomatology. Future research should continue to explore these interactions, as they hold potential for developing targeted therapeutic strategies aimed at mitigating inflammation and its effects on PD.
