Ekstraksi dilakukan dengan cara maserasi menggunakan pelarut etanol 96%. Pengujian aktivitas antibakteri menggunakan metode difusi agar (difusi Kirby dan Bauer yang dimodifikasi) dengan cara sumuran. Hasil uji aktivitas antibakteri dianalisa dengan metode One way anova, dilanjutkan dengan uji Duncan. Data Anova menunjukkan bahwa konsentrasi ekstrak 5%, 10%, 20%, 40% dan 80% telah memberikan aktivitas menghambat pertumbuhan bakteri uji. Konsentrasi efektif untuk menghambat bakteri S. aureus pada konsentrasi ekstrak 20%, 40% dan 80%, untuk bakteri E. coli pada konsentrasi ekstrak 10%, 20%, 40% dan 80%, sedangkan untuk bakteri P. aeruginosa pada konsentrasi ekstrak 40% dan 80%. Peningkatan konsentrasi ekstrak daun mayana menunjukkan semakin besar diameter zona hambat pertumbuhan bakteri.

Extraction was done by maceration using ethanol 96%. Antibacterial activity test was done by using pitting method, Kirby and Bauer agar difussion with modification. The result was analyzed by One way anova, followed by Duncan test. The result showed that extract concentrations (5, 10, 20, 40 and 80%) possess bacterial inhibition activity. Extract concentrations (20, 40 and 80%) were effectively inhibit S. aureus growth and on effective concentration to inhibit E. coli were at 10, 20, 40 and 80%, while for P. aeruginosa were at 5, 10, 20, 40 and 80% extracts. The increase concentrations of mayana extract shows high inhibition diameter of bacterial growth.
Indonesia is a tropical country with a large potential for producing vegetable oils. Pure plant oils are usually cheaper than biodiesel because there is no need to process them by the chemical reaction termed transesterification. The aim of this research project was to investigate the relationships between the iodine and saponification values of various pure plant oils and the performance and emissions of static low speed diesel engine. 50% mixtures of pure plant oils with diesel were used as the experimental fuels each being compared with standard diesel fuel as control. The pure plant oils (PPO's) compared were: palm oil, coconut oil, jatropha oil and soybean oil. Comparisons were made under full load conditions at various engine speeds as well as at a constant engine speed (1500 rpm) under varied load. Emissions were also compared under conditions of constant engine speed as well as in accordance with the European Stationary Cycle (ESC) standard for static diesel engines.

Penelitian ini bertujuan untuk menguji keefektifan media dakon modifikasi terhadap peningkatan hasil belajar matematika peserta didik hambatan penglihatan kelas V di SLB Negeri Banjarnegara. Jenis penelitian ini adalah quasi eksperimen dengan desain one group pretest-posttes. Subjek penelitian ini yaitu empat peserta didik hambatan intelektual kekas V di SLB N Banjarnegara. Metode pengumpulan data mengunakan tes hasil belajar dan observasi. Hasil tes menunjukkan ratarata nilai posttest 82,67 lebih tinggi dari rata-rata nilai pretest 57,33. Hasil observasi proses belajar peserta didik selama mengikuti pembelajaran dengan menggunakan media dakon modifikasi berada dalam kategori baik dan sangat baik. Analisis menggunakan tes tanda menunjukkan P hitung 0,031 < P (α) 0,05 yang menandakan Ho ditolak dan Ha diterima;sehingga dapat disimpulkan bahwa media dakon modifikasi efektif terhadap peningkatan hasil belajar peserta didik. Analisis menggunakan N-Gain menunjukkan bahwa skor N-Gain sebesar 0,55 dan berada dalam taraf keefektifan cukup; sehingga dapat dikatakan media dakon modifikasi memberikan pengaruh yang cukup efektif terhadap peningkatan hasil belajar matematika peserta didik hambatan penglihatan. Kata kunci : Media dakon modifikasi, hasil belajar matematika, peserta didik hambatan penglihatan.
ABSTRAK Infeksi Saluran kemih (ISK) adalah keadaan dimana saluran perkemihan terinfeksi oleh patogen yang menyebabkan inflamasi. ISK biasa ditemukan pada masa anak anak hingga manula. Pasien ISK bergejala menerima terapi antimikroba. Ada banyak jenis antibiotika dari bermacam macam golongan dalam pengobatan ISK. Penelitian ini dianalisis menggunakan metode retrospektif pada 115 pasien rawat inap RSUD Banyumas Periode Agustus 2009 – Juli 2010 dan dibandingkan dengan Pedoman Diagnosa dan Terapi RSUD Banyumas. Hasil menunjukan, penderita ISK adalah 12,17% pediatrik, 71,30% dewasa dan 16,52% Lansia. Sebanyak 74,78% pasien menunjukan positif bakteriuria dan 25,12% negatif. Terdapat 12 jenis antibiotika yang digunakan dalam 115 kasus. Antibiotika Ceftriakson sebesar 59,38% merupakan antibiotika yang banyak digunakan. ABSTRACT Urinary Tract Infection (UTI) is a condition in which the urinary tract is infected with a pathogen causing inflammation. UTI is commonly found on children to geriatric periods. Symptomatic UTI patient should receive an antimicrobial therapy. There is a lot of agents from many groups of antibiotic commonly used which are treat UTI. This research analized with retrospectif methods to 115 hospitalized patient at RSUD Banyumas in August 2009 – July 2010 and compared to Pedoman Diagnosa dan Terapi RSUD Banyumas. The result shows, UTI patient are 12,17% pediatric, 71,30% adult and 16,52% geriatric. In amount of 74,78% patient show positif bacteriuria and 25,12% negatif. There is twelve antibiotic agents are used by 115 cases. Ceftriaxone 59,38%, is poppular antibiotic.

Postparum blues conditions experienced by nearly 80% of women who have just given birth. This may occur because of unprepared delivery and becoming a mother, too low levels of estrogen, progesterone, prolactin, and esteriol levels, age and parity (young age or the number of persistents experienced may result in postpartum blues), as well as emotional support of husbands and families have a major influence in the contribution of postpartum blues. The purpose of this research is to know the description of Postpartum Mother Knowledge about Postpartum Blues at Sunggal Medan Clinic Year 2017. This method uses descriptive, measuring instrument. The population of this research is all 13 postpartum mothers in Medan singleton clinic. Sampling technique by saturated sampling, data collection using questionnaire. The result of the research is 7 (53,84%) enough knowledge, less 2 (15,28%) people and good 4 (23,07%) people. Knowledge of postpartum mother about postpartum blues Majority of respondents have enough knowledge., It is suggested that mothers increase their knowledge about postpartum blues by seeking lots of information and ask many people who have experienced postpartum as postpartum mother learning process in adapt during postpartum period.
Koneksi matematik merupakan salah satu kemampuan yang menjadi tujuan pembelajaran matematika. Koneksi matematik terjadi antara matematika dengan matematika itu sendiri atau antara matematika dengan di luar matematika. Dengan kemampuan koneksi matematik, selain memahami manfaat matematika, siswa mampu memandang bahwa topik-topik matematika saling berkaitan. Dalam artikel ini dikaji mengenai koneksi matematik yang meliputi pengertian, peran dalam pembelajaran matematika, dan kemampuan koneksi matematik dari siswa kelas 3 sebuah SMP .
Terbaru skala tanaman menangkap CO2 telah menemukan bahwa kondensasi amina ke hasil benih inti emisi amina yang sangat tinggi yang sangat sulit untuk mengkarakterisasi dan kontrol menggunakan teknik penghapusan aerosol tradisional. Pemodelan dan percobaan telah menunjukkan potensi yang signifikan untuk efisien menangkap kepadatan tinggi, partikel submikron di kolom dikemas dengan menyesuaikan kondisi operasi kontaktor. Penelitian ini menyajikan pengaruh kondisi operasi total (gas dan aerosol) emisi piperazine (PZ) diukur dengan Fourier hot-gas Transform Infrared Spectroscopy (FTIR) dari CO2 absorber bangku-besaran dengan RSR-0,3 kemasan acak menggunakan 0,9 m PZ . Aerosol diciptakan oleh penguapan dan cepat kondensasi 0,5 m PZ dan 0,05% vol asam sulfat (H2SO4). PZ adalah berbanding terbalik dengan suhu pelarut dan debit, tetapi meningkatkan independen dari CO2 inlet dengan inti biji PZ / H2O. emisi PZ yang proporsional terhadap debit dan berbanding terbalik dengan inlet konsentrasi CO2 untuk H2SO4 / H2O inti kondensasi.
