    B iolog i merupakan mata pelajaran yang konkrit yang banyak ditemukan bahkan dirasakan dalam kehidupan sehari - hari. Namun masih ada saja sebagian siswa yang menga nggap mata pelajaran ini sulit. M enurunnya minat membaca serta menurunnya minat untuk me lestarikan kebudayan. Hal ini mengakibatkan rendahnya penguasaan konsep serta kurang ke yakinan diri ( self - efficacy ) siswa dalam proses pem b e lajaran. Maka dari itu diperlukan ide - ide kreatif untuk menciptakan pembelajaran yang tepat dan inovatif. Salah satu ide kreatif dalam pemb elajaran yai tu menggunakan bahan ajar komik yang dapat mempengaruh i pemahaman, minat, belajar serta keyakinan diri ( self - efficacy ) siswa dalam belajar sehingga berpengaruh terh a d ap hasil belajar . Penelitian ini dilakukan di SMA PGRI 1 Bandung Kelas X MIA dengan jumlah 37 siswa sebagai sampel. Metode penelitian yang digunakan mixe met hod de n gan desain skuensial eksplorartori tanpa menggunakan kelas kontrol. Menggunakan 2 bentuk instrumen yaitu instrumen kualitatif dengan pengukuran versi Bandura, keyakinan siswa saat mengisi soal. Instrumen kuantitatif berupa tes objektif pilihan ganda 20 butir soal pr etest dan posttest serta angket. H asil analisis data pengukuran keyakinan diri ( self efficacy ) menunjukkan rat a - rata nilai 30,00 % dengan kategori cukup bisa mela kukan, serta pendapat keyakinan mengisi soal rata - rata nilai 78,51 % dengan kategori sangat ya ki n. Didukung dengan hasil belajar siswa dengan hasil uji gain ternormalisa s i 0,24 yang termasuk ke dalam kategori rendah. Responden siswa yang kebanyakan memberi respon positif yaitu 48,64% siswa setuju tampilan bahan ajar dibuat dalam bentuk komik .

    <p>Abstract</p> <p>Introduction</p> <p>Headache is a common presenting complaint and has a wide differential diagnosis. Clinicians need to be alert to clues that may suggest an underlying secondary aetiology. We describe a novel case of headache secondary to intracranial hypotension which was precipitated by the rupture of a spinal arachnoid cyst.</p> <p>Case report</p> <p>A 51-year-old Indian female presented with sudden onset severe headache suggestive of a subarachnoid haemorrage. Investigations including a computed tomography brain scan, cerebrospinal fluid examination and a magnetic resonance angiogram were normal. The headache persisted and magnetic resonance imaging revealed bilateral thin subdural collections, a spinal subarachnoid cyst and a right-sided pleural effusion. This was consistent with a diagnosis of headache secondary to intracranial hypotension resulting from spinal arachnoid cyst rupture.</p> <p>Conclusions</p> <p>Spinal arachnoid cyst rupture is a rare cause of spontaneous intracranial hypotension. Spontaneous intracranial hypotension is a common yet under-diagnosed heterogeneous condition. It should feature significantly in the differential diagnosis of patients with new-onset daily persistent headache.</p

    Generalised Wick Transform in Dimensionally Reduced Gravity

    In the context of canonical quantum gravity, we study an alternative real quantisation scheme, which is arising by relating simpler Riemannian quantum theory to the more complicated physical Lorentzian theory - the generalised Wick transform. On the symmetry reduced models, homogenous Bianchi cosmology and 2+1 gravity, we investigate its generalised construction principle, demonstrate that the emerging quantum theory is equivalent to the one obtained from standard quantisation and how to obtain physical states in Lorentzian gravity from Wick transforming solutions of Riemannian quantum theory.Comment: 25 pages, 3 figures, revtex4; v.2: referencing improve

SUN STAR MOTOR divided into four types, there are car sales in cash , car sales by leasing , spare parts sales in cash , and spare parts sales incredit .Variety of sales which complex will not implemented effectively and efficient without any internal control system

    Brainstem auditory evoked potentials after irradiation of nasopharyngeal carcinoma - Report on two cases with myelopathy of the brainstem

    Get PDF
    Brainstem auditory evoked potentials (BAEP) were recorded in two patients with nasopharyngeal carcinoma (NPC) irradiated and 14 and three years ago respectively and compared with 15 healthy controls. The patients had features of post-irradiation myelopathy of the brainstem with reduced gag reflex, unilateral vocal cord paralysis and fasciculation of the tongue. The first patient had a blind left eye. The second patient had quadriparesis. All ears revealed post-irradiation otitis media changes and mixed deafness. BAEP was not recognizable in the left ear of the first patient and was normal in the left ear of the second patient. Simultaneous electrochochleogram and BAEP were recorded from the right ear of the first case. The wave I-V latency interval were prolonged in both right ears. In the absence of local recurrence and brain secondaries, these BAEP changes are attributed to the post-irradiation myelopathy of brainstem.published_or_final_versio

    Analisis Efektivitas Kebijakan Kredit Untuk Menurunkan Tingkat Non Performing Loan (Studi Pada PT Bank Sahabat Sampoerna Periode 2012-2015)

    Non-performing loаn is а rаtio thаt cаn reflect the credit risk fаced by bаnks. One effort in directing bаnk lending bаsed on the principle of bаnk heаlth by providing а cleаr credit policies. This study aimed to analyze the effectiveness of credit policies on the level of non-performing loаns.In this study, the effective credit policy is meаsured by the precаutionаry principle, the orgаnizаtion аnd mаnаgement of credit, credit аpprovаl policies, documentаtion аnd credit аdministrаtion, credit monitoring, аnd resolution of problem loаns. Аnаlysis of policy effectiveness is meаsured by аnаlysis bаnkаble loаns, investment policy аnаlysis, policy аnаlysis risk, credit spreаd of policy аnаlysis, аnd аnаlysis of interest rаte policy.This reseаrch is using а descriptive reseаrch. The locаtion of this reseаrch is PT Bаnk Sаhаbаt Sаmpoernа for the period 2012-2015. The dаtа used аre primаry dаtа аnd secondаry dаtа. Dаtа аnаlysis techniques in this study using descriptive аnаlysis.The results of this study indicаte thаt the credit policy of PT Bаnk Sаhаbаt Sаmpoernа hаs not been effective in policy precаutionаry principle аnd аnаlysis bаnkаble, while other credit policy hаs been quite effective

    Irfan Dwi Risnandar, 48114202.T, 2017, "the effect of diesel supply to the motor work in MT. Madelin Expo ", Diploma Program IV, Teknika, Merchant Marine Polytechnic Semarang, Supervisor I: F. Pambudi Widiatmaka, ST., M.T. and Supervisor II: Winarno, S.ST., M.H One reason for the lack of air rinse into the combustion chamber is the result of the work of Turbocharger and Intercooler is not the maximum so that the combustion in the cylinder did not get the corresponding combustion or combustion is less than perfect. In normal circumstances turbocharger can produce a pressure of 2.3 kg / cm2 and rinse intercooler air temperature 55 ° C at room temperature 41oC machine and sea water temperature 30oC, whereas in these circumstances the resulting pressure turbocharger down to 1.4 kg / cm2 and temperature rinse intercooler rose to 63oC in the engine room temperature 41oC and 30 C temperature of sea water. Making this thesis is basically aimed to develop or pouring, thoughts, and experience into written form concerning various problems that occurred onboard, particularly those related to the lack of air supply rinse related to malfunctioning of supporting devices like turbocharger and intercooler to the maximum, who followed the evidence and facts that can be accounted, the making of this thesis also has several general purpose and special purpose. The research were conducted on the main engine will indirectly lead to problems related to the main engine. So that through these studies the problems that occur will be solved and results in a jawaban.Hasil of the study are expected to be useful for officers machines or machinist, readers and friends also have similar problems, to be used as guidance in order to obtain rinse optimum air in the combustion process in diesel motors main.
