Abstract

The Tegaldlimo branch of Banyuwangi water supply company serves 3 villages and 28 villages in the southern part of Banyuwangi district are not yet served by piped networks. This study aims to analyze the development of piped distribution networks in the short-term, medium-term term, and long-term Southern Banyuwangi Regency. The geometry method was carried out for population projection in 2042 that applied as the basis of average water demand. The calculation of water demand was simulated using EPANET 2.2, with maps of distribution pipelines to illustrate the hydraulic simulation of pipelines. The development of drinking water distribution networks in The Southern Banyuwangi Regency was divided into four stages according to the priority, namely Siliragung, Pesanggaran, Bangorejo, and Purwoharjo district. The development of the drinking pipeline network was carried out by using HDPE in diameters of 200, 180, 160, 140, 125, 110, 90, 75, and 63 mm and pump type of Grundfos UPS Series 200 with a maximum head of 18 m and a maximum flow of 70 cubic meter per hour. Keywords: development, SPAM, PUDAM  ABSTRAK PDAM Banyuwangi cabang Tegaldlimo melayani 3 desa dan 28 desa di Kabupaten Banyuwangi bagian selatan belum terlayani jaringan perpipaan.

Abstract

In the era of industry and technology in Indonesia, environmental problems due to waste are problems that require wise handling. Fly Ash (FA) waste from PLTU activities and Spent Bleaching Earth (SBE) waste resulting from the palm oil production process are very abundant, thus polluting the environment. Indonesia is currently prioritizing physical infrastructure development, which aims to improve connectivity and encourage economic growth in every sector. The development process that occurs increases the use of concrete. Concrete has a tremendous impact on the environment because most of its composition is cement. The use of cement in the manufacture of concrete results in the emission of large amounts of CO2 gas into the atmosphere, which causes an increase in global warming. The use of concrete can have a lower environmental impact if the use of cement is reduced as much as possible by adding a mixture of FA and SBE wastes. This research will utilize FA and SBE waste in the manufacture of normal concrete production weights and aim to determine the optimal composition of FA and SBE waste that is economically and environmentally feasible. The results of the research by applying FA and SBE substitutions show that FA is better than bleaching earth in the resulting compressive strength. The optimal composition of FA as a substitute for cement to achieve the quality of the planned concrete is 15%, while the composition of SBE as a substitute for cement is 10%. Keywords: concrete, Fly Ash (FA), Spent bleaching earth (SBE), concrete compressive strength  ABSTRAK In the era of industry and technology in Indonesia, environmental problems due to waste are problems that require wise handling.

Abstract

Indoor air pollution is dangerous for human health because almost 90% of human activity occurs indoors. An important factor when assessing indoor air quality is the concentration of carbon dioxide (CO2). Even at very low concentrations, it can have a marked effect on the health of those in it. The purpose of this study was to review the ability of moss used as a living wall to absorb CO2 and study its potential application in improving indoor air quality. In addition, this research will also identify challenges that may be faced in implementing living moss walls. This study used the true experimental method with a pretest and posttest control group observation design. The study was conducted by comparing CO2 levels from 2 white cigarette smoke with and without living moss wall in a prototype room made of glass with dimensions of 40 cm x 40 cm and 55 cm high.The research results show that the use of living moss wall as a solution to overcome indoor air pollution, especially CO2, cannot be separated from several obstacles that must be faced in its implementation. Living moss wall has a relatively low CO2 reduction efficiency value by using blumei’s moss (Macromitrium blumei). The use of a living moss wall must also pay attention to the suitability of the environment where it is installed so that the living moss wall can function properly.Keywords: Living moss wall, carbon dioxide (CO2), indoor air pollution  ABSTRAK Pencemaran udara dalam ruangan berbahaya bagi kesehatan manusia karena hampir 90% aktivitas manusia terjadi di dalam ruangan. Faktor penting dalam menilai kualitas udara dalam ruangan adalah konsentrasi karbon dioksida (CO2).

Tujuan dari penelitian ini adalah untuk mengevaluasi kemampuan lumut yang digunakan sebagai dinding hidup untuk menyerap CO2 dan mempelajari potensi aplikasinya dalam meningkatkan kualitas udara dalam ruangan. Selain itu, penelitian ini juga akan mengidentifikasi tantangan yang mungkin dihadapi dalam mengimplementasikan dinding lumut hidup. Penelitian ini menggunakan metode eksperimen sejati dengan desain observasi kelompok kontrol pretes dan postes. Penelitian ini dilakukan dengan membandingkan tingkat CO2 dari asap rokok putih dengan dan tanpa dinding lumut hidup dalam sebuah ruangan prototipe yang terbuat dari kaca dengan dimensi 40 cm x 40 cm dan tinggi 55 cm. Hasil penelitian menunjukkan bahwa penggunaan dinding lumut hidup sebagai solusi untuk mengatasi pencemaran udara dalam ruangan, terutama CO2, tidak dapat dipisahkan dari beberapa hambatan yang harus dihadapi dalam implementasinya. Dinding lumut hidup memiliki nilai efisiensi pengurangan CO2 yang relatif rendah dengan menggunakan lumut Macromitrium blumei. Penggunaan dinding lumut hidup juga harus memperhatikan kesesuaian lingkungan di mana dinding lumut hidup dipasang agar dapat berfungsi dengan baik.Kata Kunci: Living moss wall, karbon dioksida (CO2), pencemaran udara dalam ruangan

There is a flood that can disrupt the activities of residential residents. One alternative to overcome this is by applying the concept of eco-drainage in residential areas. This study uses a quantitative descriptive approach to the Podo Asih Housing area, hydrological analysis is carried out to determine runoff discharge and hydraulic analysis to determine the capacity of the existing channel in the Podo Asih Housing area, the analysis is carried out to determine how much runoff discharge occurs, that is the basis In eco-drainage planning, it is necessary to take into account how many rainwater reservoirs, infiltration wells, and biopore infiltration holes are needed to control the runoff water. In collecting data, researchers conducted observations and measurements directly in the field, carried out laboratory tests, and collected rain data from the Department of Irrigation and Mining of Pasuruan Regency. HEC-RAS software for hydraulic analysis calibration. The results showed that there were 39 out of 118 channels that could not accommodate runoff water discharge, planned as many as 378 rainwater collectors, 68 infiltration wells, and 289 biopore infiltration holes that could reduce runoff discharge by 1,253 m3/s with a reduction percentage of 95.59% for a 2 year return period, 77.06% for a 5 year return period, and 68.19% for a 10 year return period. Keywords: housing, runoff, ecodrainage  ABSTRAK Perumahan Podo Asih merupakan kawasan perumahan yang terletak di Kecamatan Beji Kabupaten Pasuruan, terletak pada 7°34'23.21” LS dan 112°44'00.39” BT dengan luas perumahan 50.000 m2 atau 5 hektar, perumahan yang relatif padat penduduk ini masih sering dijumpai.
