Neglected foreign body aspiration mimicking bronchial carcinoma

Foreign body aspiration can occur in any age group, but it is more commonly seen in children. In adults, there is usually a predisposing condition that poses a risk of aspiration. If aspiration occurs, prompt diagnosis and extraction of the foreign body is needed to prevent early and late complications. We report a rare case of neglected foreign body aspiration in a 45-year-old schizophrenic opium addicted patient, which resulted in an occlusive lesion in the bronchus, mimicking bronchial carcinoma. © The Author(s) 2015

MENINGKATKAN HASIL BELAJAR SISWA PADA MATA PELAJARAN BIOLOGI MATERI SISTEM PEREDARAN DARAH MANUSIA MENGGUNAKAN PENDEKATAN SAVI DAN MEDIA GAMBAR DI KELAS VIII H SMP NEGERI 02 COLOMADU, KARANGANYAR TAHUN PELAJARAN 2010/2011

Siswa kelas VIII H SMP Negeri 2 Colomadu dalam proses pembelajaran siswa ramai dan tidak konsentrasi dalam belajar (46%); siswa tidak aktif dalam pembelajaran (43%); siswa bermain dalam kelas pada waktu belajar (31%); siswa makan dalam pembelajaran (29%); kurang motivasi dalam pembelajaran (23%); siswa ngobrol ketika pembelajaran berlangsung (29%). Berdasarkan hasil observasi maka peneliti dan guru biologi memilih pembelajaran dengan pendekatan SAVI dan Media Gambar untuk meningkatkan hasil belajar biologi siswa. Tujuan dari penelitian ini adalah untuk mengetahui peningkatan hasil belajar biologi menggunakan pendekatan SAVI dan Media Gambar pada siswa kelas VIII H SMP Negeri 2 Colomadu tahun ajaran 2010/2011. Penelitian ini merupakan penelitian tindakan kelas (PTK) dengan model pembelajaran menggunakan pendekatan SAVI dan Media Gambar. Subyek dalam penelitian ini adalah siswa kelas VIII H yang berjumlah 35 siswa. Penelitian ini berlangsung selama dua siklus dan masing-masing siklus terdiri dari empat tahapan yaitu perencanaan, pelaksanaan, observasi/pengamatan dan refleksi. Analisis data pada penelitian ini dengan cara deskriptif kualitatif, yaitu dengan cara menganalisis data perkembangan siswa dari siklus I sampai siklus II. Hasil penelitian menunjukkan tindakan diperoleh rata-rata 5,1 dan rata-rata siklus I meningkat sebesar 6,3, siklus II 7,4. Menunjukan setelah diberi materi dengan model pembelajaran menggunakan pendekatan SAVI dan Media Gambar berpengaruh positif terhadap peningkatan nilai awal. Untuk aspek afektif mengalami peningkatan dari siklus I sebesar 12,3 (berminat, sedang), siklus II sebesar 16,2 (berminat, baik). Berdasarkan hasil penelitian dapat disimpulkan bahwa model pembelajaran menggunakan pendekatan SAVI dan Media Gambar dapat meningkatkan hasil belajar biologi pada materi sistem peredaran darah manusia siswa kelas VIII H SMP Negeri 2 Colomadu tahun ajaran 2010/2011 pada aspek kognitif dan aspek afektif

Massive malignant pleural effusion due to lung adenocarcinoma in 13-year-old boy

A 13-year-old boy with no risk factors for lung cancer presented with a massive left-sided pleural effusion and a mediastinal shift on chest radiography and computed tomography. A chest tube drained bloody pleural fluid with an exudative pattern. A pleural biopsy and wedge biopsy of the left lower lobe revealed mucinous adenocarcinoma in the left lower lobe wedge biopsy and metastatic adenocarcinoma in the pleural biopsy. The patient is currently undergoing chemotherapy. Radiotherapy is planned after shrinkage of the tumor. Adenocarcinoma of the lung is very rarely seen in teenagers or children, especially in the absence of risk factors. © SAGE Publications

AKTIVITAS ANTIBAKTERI ISOLAT JAMUR ENDOFIT DARI DAUN INSULIN (Smallanthus sonchifolius (Poepp. & Endl.) H. Robb) TERHADAP BAKTERI Escherichia coli DAN Staphylococcus aureus

ABSTRACTEndophytic fungi from the Insulin plant (Smallanthus sonchifolius (Poepp. & Endl.) H. Robb) produce secondary metabolites that can be used as drugs such as anticancer, antiviral, antifungal and antibacterial. The purpose of this study was to determine the antibacterial activity of endophytic fungi extract from Insulin leaves (S. sonchifolius) against Escherichia coli and Staphylococcus aureus. The study was conducted starting with the production of endophytic fungi, maceration and testing of antibacterial activity against bacteria E. coli and S. aureus using well diffusion. Endophytic fungal extract at concentrations of 100 and 50 µg/well. Showedhas strong antibacterial activities against both tested bacteria. The inhibition zone diameter for E coli was 12.87 and 10.37 mm respectively, whereas  for S. aureus  13 and 10.12 mm respectively. However, at a concentration of 25 µg/well, it had moderate antibacterial activity against S. aureus with an inhibition zone diameter of 8.12 mm and not active in inhibiting the growth of bacteria E. coli. Tetracycline positive control has a strong zone of inhibition against bacteria E. coli with an inhibition zone diameter of 15.75 mm and a very strong inhibition zone against bacteria S. aureus with an inhibition zone diameter of 21.5 mm while the ethyl acetate negative control did not have an inhibition zone against bacteria E. coli and S. aureus. Keywords: Insulin leaf (Smallanthus sonchifolius), Endophytic Fungus, antibacterial  ABSTRAKJamur endofit dari tanaman Insulin (Smallanthus sonchifolius (Poepp. & Endl.) H. Robb) menghasilkan metabolit sekunder yang dapat digunakan sebagai obat seperti antikanker, antivirus, antifungi dan antibakteri. Tujuan penelitian ini adalah untuk mengetahui aktivitas antibakteri ekstrak jamur endofit dari daun Insulin (S. sonchifolius) terhadap bakteri Escherichia coli dan Staphylococcus aureus. Penelitian dilakukan diawali dengan produksi jamur endofit, maserasi dan uji aktivitas antibakteri dengan menggunakan metode sumuran. Ekstrak jamur endofit pada konsentrasi 100 dan 50 µg/well. memiliki aktivitas antibakteri kuat baik terhadap bakteri E. coli dengan diameter zona hambat masing-masing sebesar 12,87 dan 10,37 mm dan sebesar 13 dan 10,12 mm terhadap bakteri S. aureus. Namun pada konsentrasi 25 µg/well memiliki aktivitas antibakteri sedang terhadap bakteri S. aureus dengan nilai diameter zona hambat sebesar 8,12mm dan sebaliknya tidak aktif menghambat pertumbuhan bakteri E. coli.Kontrol positif tetrasiklin memiliki aktivitas hambat yang kuat terhadap bakteri E. coli dengan diameter zona hambat sebesar 15,75 mm dan sebesar 21,5 mm terhadap bakteri S. aureus sedangkan kontrol negatif etil asetat tidak memiliki zona hambat terhadap bakteri E. coli maupun S. aureus. Kata kunci: Daun Insulin (Smallanthus sonchifolius), Jamur Endofit, Antibakter

Implementasi Data Mining Metode C.45 untuk Memprediksi Peminat Kuota Internet pada Masa Covid 19

During the Covid 19 pandemic, Telering experienced an increase in sales and there were several internet SIM cards that consumers were less interested in. Various kinds of internet cards are sold and offered to attract consumers' attention, but it cannot be predicted which internet cards the consumers will be interested in. The C4.5 algorithm is a data classification algorithm with a decision tree technique that has advantages. These advantages, for example, can process numeric (continuous) and discrete data, can handle missing attribute values, produce easy rules. The results of the study explain that all providers including Telkomsel, Indosat, and axis are in demand by consumers. In analyzing using the C.45 algorithm with the Rapidminer Tools, the first is that the decision tree results in determining consumer interest are seen from the price, while the accuracy using the C.45 algorithm or decision tree produces an accuracy of 94.67%
