Abstract

Establishing and maintaining hydrometeorological networks in sub-watersheds is challenging. An analysis of an established network of Rain Gauge Station (RGS) is provided in this study in the form of a comprehensive statistical framework. Hydrometeorological observations are monitored by this network, which aims to gather the most pertinent information while minimizing expenditures. The study location is at Ngasinan Hulu watershed (East Java, Indonesia), with ten rain gauge stations and one automatic water level recorder (AWLR). Errors in reviewing hydrological data in a watershed can cause the resulting data to be inaccurate. Therefore, to solve the problem of incorrect data, it is necessary to rationalize rain gauge stations. The rationalization for this study uses the Stepwise method. The results of the Stepwise-Enter method produce a combination of six rain gauge stations with measured rainfall data and a combination of four rain gauge stations with CHIRPS satellite rainfall data. Therefore, this combination of rain gauge stations is rational because it meets the classical assumption test, and the area is evenly distributed according to WMO standards.

Abstract

Arus lalu - lintas pada Jalan Gajah Mada dari tahun ke tahun mengalami peningkatan. Hal ini disebabkan perkembangan pada daerah Jalan Gajah Mada ini. Untuk menemukan suatu model transportasi yang sesuai pada jalan ini, terlebih dahulu diperlukan pengetahuan mengenai karakteristik lalu - lintas dan model hubungan antar karakteristik tersebut. Penelitian ini bertujuan menganalisis model hubungan antar karakteristik volume (V), kecepatan (S) dan kepadatan (D) lalu - lintas sesuai dengan kondisi yang ada dengan dasar pedoman Manual Kapasitas Jalan Indoneia (MKJI 1997). Survei data meliputi volume dan kecepatan lalu - lintas dengan metode manual counting, sedangkan analisis model meliputi model Greenshield, Greenberg dan Underwood. Hasil analisis menunjukkan bahwa untuk arah kota model yang sesuai dilihat dari nilai (R2) adalah Model Underwood sebesar 0,393 dan untuk arah luar kota yaitu Model Greenberg dengan nilai (R2) sebesar 0,43. Untuk nilai kapasitas yang mendekati hasil dari metode MKJI 1997 pada arah kota maupun arah luar kota yaitu Model Underwood.

Abstract

Abstrak Kawasan perumahan merupakan solusi untuk menciptakan pemukiman yang lebih tertata di wilayah kota dan sekitarnya, namun memiliki tantangan berupa penggunaan energi dan air yang besar, pengelolaan kawasan, dan penyediaan fasilitas untuk penghuninya. Kawasan hijau dapat menjadi solusi untuk menjadikan kawasan perumahan berkelanjutan yang ramah lingkungan, efisien dalam penggunaan energi, dan memberi kemudahan bagi penghuninya. Penilaian yang digunakan pada penelitian ini yaitu penilaian kawasan hijau yang didasarkan pada perangkat penilaian Greenship Neighborhood V.1.0 oleh GBCI. Perencanaan pekerjaan peningkatan kawasan hijau dan penyusunan cash flow dilakukan setelah melakukan penilaian kawasan. Cash flow digunakan untuk melakukan analisis investasi yang menggunakan metode Net Present Value (NPV), Internal Rate of Return (IRR), Break Even Point (BEP), Payback Period (PBP), dan Profit Ability Index (PI). Hasil dari penelitian menunjukkan Net Present Value sebesar Rp12.917.114.905,- Internal Rate of Return sebesar 28,34%, dan Profit Ability Index menunjukkan angka 1,592. Pengembalian modal yang dibutuhkan untuk mencapai Break Even Point adalah sebesar Rp73.184.818.841,-  dengan penjualan minimum 68 unit rumah tipe 43/72, 74 unit rumah tipe 45/72, 19 unit rumah tipe 90/120, dan 5 unit ruko sedangkan Payback Period menunjukkan pengembalian dalam waktu 2 tahun. Kata kunci: kawasan hijau, analisis investasi, perumahan   Abstract A residential area is a solution for creating organized settlements in the city, but have problems of large amounts of energy and water usage, area management, and facilities provided for its inhabitants. Green areas can be a solution to make sustainable residential areas that are environmentally friendly, energy-efficient, and provide convenience for their inhabitants. The assessment used in this study is the Greenship Neighborhood V.1.0 assessment tool by GBCI.  Green area improvement and cash flow are created after conducting the green area assessment. Cash flow is used to conduct investment analysis using methods of the Net Present Value (NPV), Internal Rate of Return (IRR), Break-Even Point (BEP), Payback Period (PBP), and Profit Ability Index (PI). The results of the study showed that the Net Present Value of Rp12,917,114,905, - the Internal Rate of Return of 28.34%, and the Profit Ability Index showed an index number of 1.592. The return on the capital needed to achieve the Break-Even Point is Rp73,184,818,841, with a minimum sales of 68 housing units of type 43/72, 74 housing units of type 45/72, 19 housing units of type 90/120, and 5 units of shophouses while Payback Period shows returns within 2 years. Keywords: green area, investmen analysis, housing

Abstract

Superhydrophobic coatings on cotton utilized in medical applications like hospital gowns and bed linens to offer a protective barrier against fluids and bacteria. Masks were worn with different types of materials. In this study, various cotton employed ZnO and AESO to effectively decrease the surface energy of cotton fabric via a Schiff base reaction. This chemical transformation resulted in the formation of a textured surface structure that exhibited robust adhesion qualities. The study demonstrates that the superhydrophobic coating on silk fabric increases 153. 59%. The coating on silk provides a reference for fabric types with ZnO and AESO coatings.
