Analisis Kebutuhan Dan Ketersediaan Air Domestik Di Pulau Belakang Padang

Pulau Belakang Padang merupakan bagian dari Kecamatan Belakang Padang yang terletak 12,1 km dari Kota Batam.  Pulau Belakang Padang menghadapi masalah ketersediaan air terutama saat musim kemarau. Pada tahun 2016, terjadi bencana kekeringan yang mengakibatkan masyarakat tidak mendapatkan akses air. Kekeringan yang terjadi mengakibatkan tampungan waduk menjadi kosong sehingga waduk berhenti beroperasi karena tidak ada air baku yang dapat diolah. Selain itu, pertambahan jumlah penduduk yang bermukim di Pulau Belakang Padang juga meningkat setiap tahun. Oleh karena itu, tujuan penelitian ini adalah untuk menganalisis kebutuhan dan ketersediaan air di Pulau Belakang Padang untuk 5 tahun mendatang. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif dimana dilakukan analisis kebutuhan dan ketersediaan air bersih di wilayah Pulau Belakang Padang. Berdasarkan hasil analisis yang telah dilakukan, jumlah penduduk mengalami peningkatan sebesar 0,046% pada tahun 2027 dengan jumlah penduduk mencapai 22.561 jiwa. Pada tahun 2027, diprediksi kenaikan jumlah pelanggan rumah sebanyak 1.538 SR. Kebutuhan air bersih di wilayah pelayanan Kecamatan Belakang Padang sebesar 1,7801 liter/detik pada tahun 2027 sesuai dengan proyeksi pertumbuhan jenis pelanggan. Kebutuhan harian maksimum adalah 1,9581 liter/detik, dan debit puncaknya adalah 2,6701 liter/detik. Dengan membandingkan kebutuhan dengan ketersediaan air yang ada dapat diketahui bahwa jumlah ketersediaan sumber air saat ini masih mencukupi untuk prediksi 5 tahun kedepan (10 > 1,7801 Liter/detik). Jumlah pelanggan pada tahun 2027 meningkat mencapai 1.538 SR, maka kebutuhan waduk menjadi 3,1373568 m3 kapasitas saat ini 270.000 m3 mampu menampung hingga tahun 2027.

c-Maf Transcription Factor Regulates ADAMTS-12 Expression in Human Chondrogenic Cells.

ObjectiveADAMTS (a disintegrin and metalloproteinase with thrombospondin type-1 motif) zinc metalloproteinases are important during the synthesis and breakdown of cartilage extracellular matrix. ADAMTS-12 is up-regulated during in vitro chondrogenesis and embryonic limb development; however, the regulation of ADAMTS-12 expression in cartilage remains unknown. The transcription factor c-Maf is a member of Maf family of basic ZIP (bZIP) transcription factors. Expression of c-Maf is highest in hypertrophic chondrocytes during embryonic development and postnatal growth. We hypothesize that c-Maf and ADAMTS-12 are co-expressed during chondrocyte differentiation and that c-Maf regulates ADAMTS-12 expression during chondrogenesis.DesignPromoter analysis and species alignments identified potential c-Maf binding sites in the ADAMTS-12 promoter. c-Maf and ADAMTS-12 co-expression was monitored during chondrogenesis of stem cell pellet cultures. Luciferase expression driven by ADAMTS-12 promoter segments was measured in the presence and absence of c-Maf, and synthetic oligonucleotides were used to confirm specific binding of c-Maf to ADAMTS-12 promoter sequences.ResultsIn vitro chondrogenesis from human mesenchymal stem cells revealed co-expression of ADAMTS-12 and c-Maf during differentiation. Truncation and point mutations of the ADAMTS-12 promoter evaluated in reporter assays localized the response to the proximal 315 bp of the ADAMTS-12 promoter, which contained a predicted c-Maf recognition element (MARE) at position -61. Electorphoretic mobility shift assay confirmed that c-Maf directly interacted with the MARE at position -61.ConclusionsThese data suggest that c-Maf is involved in chondrocyte differentiation and hypertrophy, at least in part, through the regulation of ADAMTS-12 expression at a newly identified MARE in its proximal promoter

Optimalisasi Rencana Anggaran Biaya pada Perumahan Central Raya Tiban Menggunakan Perhitungan SNI dan Kontraktor

In the construction project, construction management is needed in order to get results that are in accordance with the objectives of the development. One of the elements of project management is cost management. Poor cost management can lead to cost overruns or over budgets to the detriment of project owners and contractors. One of the methods that can be used in preparing the project cost budget is the SNI calculation and the contractor's calculation. The purpose of this study was to determine the comparison of the budget plan using the SNI method and the contractor's calculation. The research was conducted by collecting data on the Central Raya Tiban housing development project. Furthermore, an analysis using the SNI and contractor is carried out and compares the results of the calculations of the two methods. The results of the study obtained that the estimated cost budget plan from the calculation of the contractor was Rp. 283,827,332, while the results with the SNI were Rp. 330,333,371. From these data, it can be seen that the contractor's calculation is more optimal when compared to the calculation of SNI with a difference of Rp. 46,506,039 or 14.08% of the total value of the estimated cost budget based on the SNI calculation method. This can be used as a reference in preparing a cost budget in order to reduce development or project costs so that they become optimal and in accordance with the wishes of the project owner
