Analisis Kinerja Sistem Drainase Kelurahan Kuto Panji Kecamatan Belinyu

Kelurahan Kuto Panji merupakan salah satu kelurahan di Kecamatan Belinyu yangmemiliki permasalahan pada sistem drainase. Hal ini dikarenakan sering terjadinya banjirsaat musim penghujan. Kapasitas tampang saluran tidak mampu menampung air hujansehingga menyebabkan banjir yang mengganggu aktifitas masyarakat serta arus lalulintas. Tujuan dari penelitian ini adalah untuk menganalisis kinerja sistem drainaseKelurahan Kuto Panji Kecamatan Belinyu. Dalam analisis kapasitas tampang saluran,perhitungan dilakukan berdasarkan debit rencana, sedangkan penilaian indikator fisikberdasarkan bobot yang telah ditentukan. Data yang digunakan adalah data curah hujan,peta administrasi, peta kontur, peta tata guna lahan dan outline plan drainase KotaBelinyu. Berdasarkan perhitungan dan kondisi eksisting di lapangan diperoleh hasilbahwa ada beberapa saluran sekunder yang tidak mampu menampung debit rencana yaitusaluran sekunder S2, S3, S4, S6, S8, S11, S12. Sedangkan tingkat kinerja sistem drainaseterhadap indikator fisik yang dinyatakan dalam score adalah kurang (diperoleh totalpengalian nilai dengan bobot sebesar 6015 ≤ 6100) menurut Kementrian PekerjaanUmum. Diperlukan solusi terhadap permasalahan banjir antara lain dengan carapembersihan dan pemeliharaan saluran drainase dari semak, diperlukannya saringansampah dan normalisasi saluran berupa pengerukan secara berkala serta sumur resapanpada bangunan di pinggir saluran.Kata kunci : banjir, debit rencana, indikator fisik, sistem drainas

Analisis Willingness to Pay (Wtp) Dan Kebutuhan Air Di Kecamatan Merawang

The population growth and diversity of activities in the community in various fields occasion requirement of water have an important issue. Especially, supply of clean water. However, the availability of water in the Merawang Subdistrict had occurs dryness cause by drought in the 2015. Finally, many people using services from the Water Supply Company (PDAM) Tirta Bangka, Merawang Subdistrict. This indicated that there is a high ability and willingness of people to pay for services of PDAM. Therefore, in this research aims to examine the relationship between Willingness to Pay (WTP) of clean water in PDAM with the urgent water needs. Type of research is quantitative research, which is located in four villages in the Merawang Subdistrict. Such as Baturusa village, Riding Panjang village, Dwi Makmur (Sunghin) village, and Merawang village. In this case, we use Contingent Valuation Method (CVM) which using questionnaires and interviews to respondents in the village. The results of research showed that the rates paid by people who are willing to be in the range of Rp.50000.00/month until Rp.99000.00/month, average Rp.73378.00/month. Based on the results, tariff of WTP is Rp.2197.00/m3. In addition, from the analysis obtained the PDAM Tirta Bangka in Merawang was installed capacity of 10 l/s and water needs in the four villages, which is constitute the PDAM service area of less than 10 l/s. This suggests that the capacity of Water Supply Company (PDAM) Tirta Bangka has enough supplies for 10 years in Merawang Subdistrict

Evaluation and correlation of mammographically suspicious lesions with histopathology at Addington Hospital, Durban

Background. Stereotactic core-needle biopsies (SCNBs) are a reliable alternative to surgical biopsy for microcalcifications. The positivepredictive value (PPV) of SCNB has been shown to be reproducible in several studies using the Breast Imaging Reporting and Data System(BIRADS) classification, which is the current gold standard in mammographic reporting. At this stage, no study has been done in KwaZulu-Natal to assess local outcomes against BIRADS. The current standard of care utilises vacuum-assisted breast biopsy, but is not availablein a resource-constrained environment such as ours. The need, therefore, is for constant evaluation of existing practice to ensure that it isoptimised for the challenges and limitations facing local radiologists.Objective. To assess the PPV of SCNB in Addington Hospital, and to compare it with that of BIRADS.Material and methods. Mammographically detected lesions were assigned to 3 categories: benign, indeterminate and suspicious. Aretrospective review of 67 SCNBs was performed for lesions falling within the suspicious category, and the PPV and rates of ductalcarcinoma in situ (DCIS) were determined.Results. Our study demonstrated a PPV of 20.9%. This correlated well with international studies for BIRADS 4 and 5 lesions. DCISaccounted for 21.4% of detected malignancies, which is in keeping with current literature.Conclusion. Despite resource limitations, local outcomes were comparable with those of BIRADS. Given our fairly general categorisationof lesions, however, it should be emphasised that BIRADS allows better organisation, consistency and clarity in breast imaging reporting,as well as accurate data comparison between centres facing limitations similar to our own

The ϵ\epsilon-ζ\zeta Transition in Solid Oxygen

The structure of solid oxygen has been studied at pressures from 50 to 140~GPa using static structure search methods and molecular dynamics simulations with density functional theory and a hybrid exchange functional. Several crystalline structures with space group symmetries {\it Pnma}, {\it P}\,2$_{1}${\it /m}, {\it Pm} and {\it P}\,6$_3$/{\it mmc} have been identified as candidates for the $\zeta$ phase of oxygen at 0~K. Within the hybrid exchange functional framework and at 300~K temperature, {\it Pm} is shown to be energetically most favorable above 111~GPa. A comparison with experimental X-ray diffraction, spectroscopic and superconductivity measurements is provided for all competing structures.Comment: 6 pages, 5 figure

Peningkatan Motivasi Murid Menggunakan Metode Demostrasi dalam Mempelajari IPA Kelas III di Sekolah Dasar

Motivation to learn in the third grades students of SDN 11 Padang Sepan Kapuas Hulu is still lacking, especially in the learning process. In connection with the above issues need to be improved to enhance the students learning motivation. The purpose of this research is to increase the intrinsic motivation and extrinsic motivation of student to learn and see the impact of learning on learning outcomes. Researchers used the descriptive method and from of action research is a collaboration between the researcher with colleagues. Setting and subject of research conducted in the classroom with the research subject is the teacher and students who are 17 students with composition 11 boys and 6 girls. Each cycle consist of planning, implementation, direct observation and data collection tool as guide for the student and teacher abservation data obtained from each cycle are : Pupil instrinsic motivation increased from the baseline to the third cycle 57,52%, and pupil motivation ekstrinsic increased from the baseline to the third cycle 79,00%

Peningkatan Aktivitas Peserta Didik Menggunakan Pendekatan Saintifik Kelas II Sekolah Dasar Negeri 06 Ketapang

This study in the background backs by a lack of learning aktivtas implemented previously. The problem is to increase the activity, with the aim of menerapkakan steps thematic learning to use the scientific approach to enhance the learning activities of students of class II SDN 06 Delta Pawan Ketapang. Form of research is the institutional survey. The subject teachers and 20 students of class II SDN 06 Delta Pawan Ketapang. conducted in two cycles of action.
