Abstract

Nowadays, coffee is one of needs among metropolitan people. This lifestyle impact to increasing waste along coffee production, one of them is coffee ground. Coffee ground has toxic properties to the environment such as caffeine, tannins, and polyphenols. While other chemicals contain on coffee ground are 2.28% nitrogen, 0.06% phosphorus, 0.6% potassium, which means has a good impact to the soil. In existing condition, coffee grNowadays, coffee is one of needs among metropolitan people. This lifestyle impact to increasing waste along coffee production, one of them is coffee ground. Coffee ground has toxic properties to the environment such as caffeine, tannins, and polyphenols. While other chemicals contain on coffee ground are 2.28% nitrogen, 0.06% phosphorus, 0.6% potassium, which means has a good impact to the soil. In existing condition, coffee ground is commonly used to, biodiesel and bioethanol or by direct used to the soil. The processing of coffee ground to be liquid organic fertilizer by using bio-activator are considered to substitute the direct used, it will improve the quality of soil. Objectives: The objective of this research is to study of liquid fertilizer from coffee ground, whether comply or not to the standard regulation Ministerial Decree of Agriculture of the Republic of Indonesia Number 261/2019. Method and results: This research use a coffee ground from arabica and robusta coffee and applied 2(two) different dilution by repeated 2x2 on one time by using EM4 as bio-activator.  The pH and temperature for 4 experiment measured daily and has an average on 4.8 and 31-degree celcius for 10 days.

Abstract

PT X has needs Waste Water Treatment Plant (WWTP) to reduce the high value of TSS and organic matter levels for the wastewater of glycerin production. The objective of the experiment is to design the dimensions of the primary sedimentation unit at PT X. This design is expected to reduce wastewater TSS levels up to 50 to 70 percent and BOD levels up to 25 to 40 percent. The design stages in this experiment include determining the quantity of wastewater discharged by PT X per day through production operations, quality testing wastewater, and designing primary sedimentation units. PT X wastewater quality testing includes measuring pH, ammonia, TSS, COD, BOD, oil & grease. The parameters are determined based on the basic oleochemical industry quality standard according to the Ministerial Regulation Environment Number 5 of 2014.  The primary sedimentation unit design in WWTP PT X was rectangular. The quantity of discharge of wastewater entering primary sedimentation tank of 0.00139 m3/second and detention time designed for 4 hours. Sedimentation tank volume is based on the calculation of 10 m3 with a multiplier of 1.1 so that the actual volume of the sedimentation tank is 11 m3. Based on the calculation results, the length of the tub is 4 m, the width of the tank is 1.1 m, 2.5 m deep, and 0.5 m freeboard. TSS level allowance and BOD that occurs in the primary sedimentation unit is the TSS level of 62.99% and BOD levels of 40.82%.

Abstract

Abstract. The problem of household waste faced in industrial areas is becoming increasingly urgent, considering that industrial areas are areas that are growing very rapidly. Jababeka Smart Township initiative is one of the efforts to provide services to the community, to improve sustainable living. In waste management, it takes the amount of waste generated to be managed, so that the measurement of household waste generation is the first step needed. Objectives: The objectives of this research are to know the waste generation at Jababeka residential, to know the waste generation of Mekarmukti village, and to analyze the waste generation in Jababeka area.   Method and results: The method of measuring household waste generation used follows SNI 19-3964-1994. The population used in this study were Mekarmukti villagers, both living in housing and outside housing. Purposive sampling method used in find the sample, method of data collection was observation, and descriptive statistics used for data analysis. The result found that the average waste generation from people at Jababeka residential is 0.33 kg/day/person, and out of residential is 0.37 kg/day/person. In Mekarmukti village, center of waste recycle could used to manage the household waste Based on this average waste the potential technology could implemented the solid waste management. Conclusion: The average waste generation in Jababeka residential is 0.33 kg/day/person and outside of residential is 0.37 kg/day/person, and this amount still less than the average waste produced per person per day in Indonesia.

Abstract

Phytoremediation is a technique that uses green plants, such as spices (e.g., Thlaspi Caerulescens, Brassica Juncea, Helianthus annuus) and woody plants (e.g., Salix spp, Populus spp), to eliminate, absorb, or convert different hazardous chemicals to the environment, such as heavy metals.

Abstract

Abstract. The Solomeronda River is a water source that currently supplies the clean water needs of the residents of Konawe Regency, with a very useful function for the community, namely for bathing, cooking and as a source of raw water for Regional Drinking Water Companies (PDAM). However, the Solomeronda River is still affected by several community activities that can reduce the quality of river water, such as felling trees and disposing of organic and inorganic waste into river bodies. These community activities will certainly affect the water quality of the Solomeronda River. Purpose: To analyze the status of river water quality through water sampling. Methods and results: Analysis of water quality status was carried out by taking water samples at three stations, namely station I (upstream), station II (middle), station III (downstream) and analyzed in the laboratory with water quality parameters analyzed including physical parameters, chemical parameters and microbiological parameters. The results of water quality measurements were then analyzed using the pollution index method. The results showed that the pollution index of the Solomeronda River at station I was 0.87 (meets quality standards), station II was 0.91 (meets quality standards) and station III was 1.1 (lightly polluted). Conclusion: Overall the pollution index value of the three stations on the Solomeronda River after being averaged has a value of 0.96, it is concluded that the status of the water quality of the Solomeronda River is included in the classification of meeting quality standards (good condition).

Abstract

Abstract. Human needs are increasing day by day. To meet these needs, one of the things that should be done are produce these materials or needs, this is related to the manufacturing industry. One of these manufacture is the metal and plastic industry. The manufacturing industry is growing rapidly and is diverse, causing a large environmental effect or influence, if environmental management or control is not carried out. Objectives: One of the efforts that need to be done to protect the environment is conduct a Life Cycle Perfective (LCP) analysis related to the implementation of 3R (Reduce, Reuse, and Recycle). In this study, analyzing the Life Cycle Perspective through the application of the 3R in each production activity or production support. Method and results:This research is done by literature study, observation, and analizing this situation Conclusion: The benefits of this 3R application are felt by the industry, in addition to making production activities more effective and efficient, increasing customer trust, and becoming a culture in environmental protection and environmental prevention activities in the company as well as the actions of every employee. In the future, it will be improved and re-evaluated in accordance with existing production activities and continuous industrial enhancement.
