Abstract

Water is one of the most important elements for humans but nowadays, the growing demand for clean water and increasing water scarcity are serious issues that must be addressed. As an alternative solution, optimizing the use of high-intensity rain in Indonesia through a Rainwater Harvesting system can help and support the water conservation efforts conducted in the green campus concept. The purpose of this final project is to calculate the cost and saving possibility through applying the rainwater harvesting system both in terms of water saving possibility and economic saving and provide the design of a rainwater harvesting system unit that is suitable for the Building A of President University. The observation method was used in this final project to find out what is the water quality of the rainwater harvested and also used the documentation method for processing the secondary data. Using the given rainfall data, the rainwater supply, in year water saving through the use of rainwater harvesting system can reach around 148.8 – 154 m3/year and save around Rp. 208,320 over the year for water costs. The storage tank capacity of the system was the size of 840 liters with the gutter 9 inches in diameter and the distribution pipe diameter 8 inches.

Abstract

Abstrak. Air limbah dihasilkan dari aktivitas manusia, baik industri maupun domestik. Air limbah domestik berasal dari kegiatan rumah tangga seperti mandi, mencuci, jamban, dan wudhu. Indonesia sebagai negara dengan mayoritas penduduk muslim menghasilkan air limbah wudhu yang dihasilkan setidaknya dari lima kali ibadah solat wajib. Secara umum, air limbah dapat diolah dengan berbagai teknologi, salah satunya adalah teknologi sentrifugasi. Teknologi sentrifugasi adalah salah satu teknologi proses untuk memisahkan partikel tersuspensi dari air limbah. Tujuan: Penelitian ini berfokus pada penggunaan teknologi sentrifugasi untuk mengolah air limbah wudhu yang bertujuan untuk mengetahui kemampuan teknologi sentrifugasi dalam pengolahan air limbah wudhu dalam hal efisiensi penyisihan dan penetuan kondisi proses optimum sehingga dapat menghasilkan efluen sesuai baku mutu air permukaan. Parameter indikator yang diamati sebagai acuan untuk mengamati perubahan kondisi efluen hasil pengolahan adalah tingkat kekeruhan (turbidity) dan konsentrasi total padatan terlarut (TSS). Metode dan Hasil: Penelitian ini merupakan penelitian skala laboratorium yang menggunakan unit sentrifugasi sebagai instrumentasi utama. Air limbah wudhu akan diolah pada berbagai variasi kombinasi perlakuan antara lain variasi kecepatan rotasi 500, 1500, 3000, 4500, dan 6000 rpm dan variasi durasi sentrifugasi 1, 3, 5, 8, dan 10 menit dengan penambahan kaolin pada dosis 25, 50, dan 75%. Kesimpulan: Hasil pecobaan menunjukan bahwa rentang penyisihan kekeruhan berada pada nilai 16,1-99,4% dan 0,9-92% untuk penyisihan parameter TSS. Kondisi optimum proses penyisihan dapat dicapai pada kombinasi perlakuan durasi 1 menit, kecepatan sentrifugasi 6000 rpm dan dosis kaolin 75%.

Abstract

Abstract. Population growth, regional development, and inaccuracy in planning targets will impact and disrupt food self-sufficiency Objectives: Analyzing and evaluating Carrying Capacity (CC), Assessing and analyzing land requirements in North Kalimantan Province Method and results: The research method is qualitative, which is analyzed descriptively quantitative. The formula of CC developed from a combined concept of the theory of Odum, Cristeiler, E Howard, and Issard. The results showed that the food carrying capacity of North Kalimantan Province in 2020 was 0.56 and land requirements for paddy 26.912 ha. Food carrying capacity is projected to decline to 0.28, and land requirements for paddy will increase to 38.479 ha in 2037. Conclusion: North Kalimantan Province's Food carrying capacity was incapable of food self-sufficiency (Class III) and continues to decline from 2016-2020 until projected in 2037. Added paddy-harvested area or land in 2037 is needed to realize food self-sufficiency through an alternative policy of expanding paddy fields (extensification) by maintaining productivity stability or increasing productivity (intensification).

Abstract

Rangkasbitung Sub-district (105 25’ – 106 30’ EL and 6 18’ – 7 00’ SL) is the capital city of Lebak Regency which has an area of 7,252 Ha. Based on the Master Plan of Lebak Regency 2014 – 2034, It will be built the toll roads and industrial areas in Nameng Village, Citeras Village, and Mekarsari Village. Therefore the Rangkasbitung will become a rapidly growing urban area. The sanitation services are still 60,63%. To achieve the Goal 6 of SDGs, then this paper aims to design an analytical technique the sewerage system in order to achieve sanitation for all, and to recommend the planning phases in order to be effective and efficient sewerage system until the end of the 2040. The Sewerage system design has anticipated the Ciujung River and Ciberang River with seven (7) tributaries that pass through this sub-district. The location of the Waste Water Treatment Plant (WWTP) is designed at a low elevation, namely in Kolelet Wetan, Nameng, and Mekarsari Village by considering the flood-free areas and topography. The recommendations for the construction phases are based on population density and the service area of the WWTP location. The total wastewater discharge is designed as 510.367 L/sec, which will be implemented into two phases. The first phase will build WWTP A = 208.937 L/sec and WWTP B = 275.188 L/sec, then WWTP C = 26.242 L/sec in the second phase. The design of the trunk sewer has a total 24,556 m length, of which 19,043 m will be in the first phase and 5,513 m will be in the second phase. The diameter of the trunk sewer ranges from 300 mm to 1,000 mm. The first phase indicated depth by diameter (d/D) ratio in the range of 55% - 78%, and the velocity range of 0.68 – 2.24 m/sec. The final phase indicated 61% - 75% and the velocity range of 0.69 – 2.24 m/sec.

Abstract

Abstract. There is a good potential between the increase in the growth of the textile industry, especially on a small scale which also causes a lot of environmental pollution of colored water in the water bodies of the area around the textile industry With the great potential of using Eco Enzyme which can be used as a biocatalyst. Eco Enzyme contains several types of enzymes, which can be used as tools to speed up the textile wastewater decoloring process which is included in the Biological method in textile wastewater treatment. Objective. To find out what are the results of color removal efficiency after adding by Eco Enzymes, and its effect on the pH values. Methods and Results. In this research, by using 10% concentration from Orange and Dragon Fruit Peels. The sample that was added by Orange Eco Enzymes (OEE) and Dragon Fruit Eco Enzymes (DEE) has a color removal respectively in 80% and 82% in 48h then continuously slowly degrades slowly to 86% and 86% in 120h. Before adding the Eco Enzyme, the sample has a high pH of 10.98. After added by OEE and DEE, in 48h respectively the pH values decrease to 9.58 and 8.98, then continuously slowly degrades to 8.70 and 8.56 in 120h. Conclusion. The results show that selected Eco Enzymes are able to decolor textile wastewater also following by reducing pH and already stable starts from 48h.
