Abstract

Introduction. Obesity becomes one of concern for surgeon asit provides additional morbidity in breast cancer. It influencesthe healing process negatively, and increase the complications following mastectomy. The most often found complication is seroma. Its incidence in obese is found higher than non–obese patient. Studies evaluating the correlation between obesity and seroma showed controversy. Hence, we run a study aimed to find out such a correlation in our characteristics. Method.We conducted cross sectional study. All patients treated with modified radical mastectomy (MRM) during period of 2013 to 2014 were included. Subject characteristics were recorded, including age, body mass index (BMI). Bilateral breast malignancy, diabetes mellitus and hypertension were excluded.Drain production and infection, and length of staywas recorded. Kolmogorov Smirnov test is used to find out normal distribution. In normal distribution, Pearson test or Spearman’s is used to find out correlation. Results. Out of 72 samples underwent MRM and drainage, there were 67 enrolled. The mean age was found of 48.5±8.5 years, and mean BMI of 25.43 kg/m2 ± 4.08.Length of stay ranged of 3–8 days andmean total seroma production was found of 502.3mL ± 207.8. We foundmoderate positive linear correlation between obesity and seroma (r = 0.581; p <0.01; r2 = 0.338) rolled of 33.8% and strong positive linear correlation between seroma and length of stay (r = 0.581; p <0.01;r2 = 0.542)rolled of 52.4%. Conclusion. We found positive linear correlation between seroma and obesity, and positive linear correlation between seroma and length of stay

Abstract

Introduction. Skin cancer is one of many kinds of cancer which incidence increases globally. Basal cell carcinoma (BSC) and squamous cell carcinoma (SCC) are the most common prevalence of non–melanoma skin cancer, and also are the most common cancer among skin cancer. The main therapy for such skin cancer is wide excision within its safety margin added by adjuvant therapy. Despite adequate therapy, people with skin cancer still have a risk of recurrence. This study assesses the prognostic factors of recurrence among people with non–melanoma skin cancer who underwent wide excision surgery. Method. This study was a retrospective cohort with survival analysis. The patient's data who underwent wide excision surgery were from Perhimpunan Ahli Bedah Onkologi Indonesia (PERABOI)registry and medical record from Oncology Surgery Division in RSCM from January 2012–December 2015. Data selection was done based on inclusion and exclusion criteria. Results. There were 187 patients with non–melanoma skin cancer who underwent wide excision surgery; the recurrence was detected on 15% of the case. Most of the patients were ≥45 years old with the most common histopathological feature of the skin cancer was basal cell carcinoma. We did a survival analysis with Cox regression and the result was previous history of skin cancer (RR 6.903; 95% CI 2.925–16.292), perineural invasion (HR 3.818; 95% CI 1.561–9.340), location of the lesion (HR 0.071; 95% CI 0.022–0.228), and size of the tumor (HR 1.842; 95% CI 1.244–2.729) was the factorsthat increased recurrence. Conclusion. History of previous skin cancer, perineural invasion, location of the lesion, and size of the tumor were the prognostic factors for recurrence among patients with non–melanoma skin cancer who underwent wide excision surgery

Abstract

Introduction. The total number of patients with thyroid nodules, especially large thyroid nodules (> 6 cm diameter), is increasing. However, the conventional suturing technique for closure of thyroidectomies is still only recommended as the standard for the tumor with a diameter up to 6 cm. Hence, this study aims to prove another surgical technique, purse-string stitching technique, for better esthetic outcomes on large thyroidectomy. Methods. This study was a non-randomized control trial. The subjects included the patients of Cipto Mangunkusumo Hospital in 2013 to 2014 with a thyroid tumor > 6 cm in diameter without any history of anterior cervical surgery and positive lymph nodes. Subjects were divided into the purse-string group and the conventional group. Thyroidectomies were done on all subjects, then were closed by the suturing technique of each group. Outcomes were recorded in the follow-up sessions, including wound scar size, wrinkle existence, and subject’s satisfaction level. Results. Purse-string technique resulted in shorter scar length compared to the conventional technique (median 35 mm vs. 94 mm, p< 0.01). The other outcomes, such as the width of the scar (median 3 mm vs. 2 mm, p=0.265), the presence of wrinkles (0 vs. 2, p=0.480), and satisfaction level of subjects (median 9 vs. 9, p=0.287) were also assessed. Conclusion. The purse-string suturing technique on large thyroidectomy wound closure could be an alternative, besides the conventional suturing technique for a better esthetic result.

Abstract

Banjir adalah salah satu bencana yang sulit dihindari yang dapat terjadi tanpa peringatan. Penyebab banjir yang utama adalah luapan dari sungai. Umumnya curah hujan yang tinggi dan kemampuan drainase tanah yang rendah menyebabkan air sungai naik sehingga terjadi banjir. Oleh sebab itu dibutuhkan sebuah sistem pemantauan peringatan dini banjir yang terintegrasi dengan masyarakat atau operator secara langsung. Untuk mencegah banjir akibat luapan air sungai, telah dirancang sebuah alat rancang bangun dan proptoptype sistem peringatan dini berbasis Arduino uno dengan menggunakan metode fuzzy logic. Alat ini bekerja dengan dua sensor, yakni sensor Ultrasonik untuk ketinggian aliran air sungai dan water flow sensor untuk kecepatan alirannya. Saat kedua sensor mendeteksi nilai yang melebihi set point yang ditentukan, aktuator motor DC akan berputar untuk mengangkat pintu air. Data nilai sensor juga akan ditampilkan oleh LCD, kemudian buzzer dan lampu indikator sebagai penanda peringatan. Pada saat sistem bekerja maka operator yang menjaga akan mengetahui level dan kecepatan aliran sungai pada saat air sungai naik, sehingga dapat terdeteksi sebelum terjadi luapan yang berakibat banjir. Hasil perancangan dalam penelitian ini telah sesuai yang diharapkan bahwa kecepatan putaran motor yang dihasilkan dipengaruhi oleh data yang terdeteksi dari kedua sensor, kemudian jarak jangkauan sistem, dan perangkat android dapat mendeteksi sampai 15 meter bila tidak ada penghalang, sehingga secara keseluruhan sistem dapat bekerja dengan baik. Dengan demikian, hasil perancangan sistem peringatan dini menggunakan sensor ultrasonik, water flow sensor dengan metode fuzzy logic dalam perancangan dan penelitian ini merupakan solusi yang tepat untuk pencegahan luapan sungai yang berakibat banjir.

Abstract

Teori Fisika tentang Relativitas membuka pemahaman baru fisika dan kosmologi. Sejak dimulai peradaban manusia, bahasan tentang kosmologi selalu terkait dengan aspek teologi atau ketuhanan. Teori awal kosmoslogi adalah Geosentris, bahwa bumi sebagai pusat kosmos dan alam semesta diciptakan seketika oleh Tuhan. Pemahaman dan Tafsir klasik Kitab Suci agama Abrahamik dinilai sejalan dengan teori Geosentris. Teori Heliosentris – Matahari sebagai pusat kosmos muncul abad ke 16 menggeser faham Geosentris. Faham Heliosentris membuat bahasan kosmoslogi lepas dari konsep-konsep teologis. Terjadilah dikotomi agama dan sains. Konsep Penciptaan kembali muncul di awal abad ke-20 setelah teori Relativitas Einstein menjadi fondasi dalam memahami kosmologi kontemporer. Tulisan ini membahas implikasi teori Relativitas dan perkembangan kosmologi terhadap pemahaman tentang Ketuhanan atau Teologi Kontemporer. Penelitian tulisan memenggunakan metode penelitian kualitatif dengan pendekatan Studi Kepustakaan (Liberary Research) dan analisis yang dikembangkan menggunakan metode analisis deskriptif, dengan konsep keterpaduan sains dan teologi. Hasil penelitian tentang relativitas bahwa ruang dan waktu besaran relatif, menjadi dasar pemahaman teori perkembangan kosmos. Sesuai Hukum Hubble, alam semesta terus berkembang dan bila dirunut mundur, alam semesta berasal dari “Dentuman Besar” sekitar 13,8 milyar tahun lalu. Sebelum dentuman besar, Volume Alam Semesta = nol , artinya belum tercipta ruang dan juga waktu, yang ada adalah “Ketiadaan”. Implikasi teori Relativitas terhadap Teologi adalah konsep ilmiah alam semesta dari “Ketiadaan” menjadi “Ada” yang bukan dari teks kitab suci, meneguhkan keyakinan akan adanya Sang Pencipta, yakni Tuhan.

Abstract

Solar energy as new and renewable energy (NRE) in Indonesia has great potential, reaching 4800 watt-hours/m2 per day because Indonesia's geography is in the tropics. Therefore, its use for direct electricity generation with environmentally friendly photovoltaic effects has received great attention from the government and the public. This article describes the development of the use of photovoltaic solar energy, its working principles, efficiency and how photovoltaic electricity is becoming an energy source that is increasingly developing today. World photovoltaic solar power generation (PLTS) in 1996 was only 0.3 GWatt to 303 GWatt in 2016, an increase of 1000 times in 20 years. The efficiency of photovoltaic systems has increased from 6% in the 1950s, now reaching 20%. In Indonesia, in 2021, photovoltaic electricity will contribute 1.8% of New and Renewable Energy (EBT), which consists of hydro, geothermal, wind and biomass energy. In 2025, it is targeted to contribute 22% of EBT after the Bintan PLTS mega project with a capacity of 3.5 GWatt operates, part of which will be exported. Photovoltaic solar energy has large and significant potential to be used as a long-term alternative energy source in the future and can be transmitted more efficiently. Meanwhile, operational cost constraints for residential PLTS are reduced by synergy with the PLN electricity network with On-Grid installations, which saves the cost of batteries, which are still high in price, besides electricity can be sent to PLN.

Abstract

Filling system technology is a technology for filling liquid into cups continuously which will make it easier for companies or small entrepreneurs to make drinks. In this technology, an Arduino Atmega 2560 microcontroller is needed as a system control, and an InfraRed (IR) sensor to detect the presence of an object (cup). This filling system technology is used continuously, using a conveyor as a tool to move objects from one place to another. The transfer of the place must have a fixed location so that the conveyor system has economic value. From this filling system, it achieved a success rate of 95% overall, while for sensor accuracy, it was obtained as much as 88% of the 20 cups that had been tested. While for filling milk in 10 cups, the average result was obtained on the first pump, which was 37.5 ml, and on the second pump, which was 49 ml.
