Abstract

One of the most abundant high-carbohydrate foodstuffs in Indonesia is cassava, this is what Keripik Kaca (Glass Chips) AKOPA uses as a MSME Partner which is the target of Community Service activities from Universitas Satya Negara Indonesia. The main objective of this community service activity is based on optimizing Keripik Kaca AKOPA’s waste to be used as cassava flour or tapioca flour. The methods used include training and mentoring as well as evaluation of activities to ensure the quality of the services presented. Based on the results of community service, a cassava-based derivative innovation transfer product was obtained, namely Cassava Flour. The product will be marketed through various online channels. This is done in order to increase the usability value as well as the selling value of cassava-derived products.

Abstract

This study aims to obtain information and determine the effect of Staphylococcus aureus in the room against sick building syndrome (SBS) on front office employees and operational space at PT Unilab Perdana, South Jakarta. The location of the study was conducted at PT Unilab Perdana, South Jakarta. When the study was conducted in March to July 2019. The results showed that: the influence of SBS symptoms at the front office location were 44 people, an average of 9 colonies of staphylococcus aureus bacteria. While the influence of SBS symptoms in the operational space location was 64 people, with an average of 18.3 colonies of staphylococcus aureus bacteria. The number of employees in the operational room experienced a frequency of Sick Building Syndrome (SBS) complaints dominated by headaches, fatigue, difficulty concentrating and nausea and dizziness with a category 1-3 times as many as 8 people (53.33%). The cause of the number of employees who are in the operational room experiences the frequency of Sick Building Syndrome (SBS) complaints because of the large number of employees who are in the operational space location, and employee activities are centralized in the operational space. Thus, there is an effect of the number ofstaphylococcus aureus bacterial colonies in the room on Sick Building Syndrome (SBS) in front office employees and the operating room of PT Unilab Perdana, South Jakarta. The dominance of symptomsand frequency of Sick Building Syndrome (SBS) complaints occurred in employees in the operatingroom of PT Unilab Perdana, South Jakarta

Abstract

Activated carbon is a material that contains high carbon elements and has a porous solid. The material used in this research is a nutmeg shell. The purpose of this study was to determine the effectiveness of activated charcoal from the shell of nutmeg (Myristica fragrans) as activated carbon in treating domestic wastewater. The variables studied to compare the effect of the wastewater absorption process are the concentration of the chemical NaOH 15% with temperature variations of 400ºC, 450ºC, and 500ºC. The best activation results were obtained at a temperature of 450ºC with a water content of 4.22%, an ash content of 10.24%, and iodinecontent of 577,395 mg/g. Activated charcoal parameters refer to SNI 06-3730-1995 regarding the quality standard requirements for activated charcoal. Wastewater management by activated charcoal from the shell of nutmeg (Myristica fragrans) with a concentration of 10, 15, 20 grams of activated charcoal. The best results were obtained by the concentration of activated charcoal 20 grams with a pH value of 9.0, TSS 0.663 mg/L, BOD 7.3 mg/L. For pH parameters, the effectiveness of activated charcoal is less than the maximum, and it does not meet quality standards.

Abstract

Water is an important resource for human life and other living things, and is also a valuable capital investment. Water quality is a problem because of the large amount of waste generated by human activities. This waste includes things like wastewater from households, factories, and other activities. Therefore, an effective micro-organism-4 (em4) is needed to treat wastewater. The purpose of this study was to determine whether the use of EM4 can reduce the amount of pollutants in hospital waste. The research method used is a laboratory experimental method used to study the effect of the variables studied. Experiment using the formula . The results of this study show the effectiveness of pollution levels using EM4 culture with a time of 16 days with the highest efficiency value found on day 16 in each parameter. Treatment on day 0 shows BOD 20.035 mg/L until treatment on day 16 results in BOD value of 6.087 mg/L and the second repetition (Y2) treatment on day 0 shows BOD value of 20.022 mg/L until treatment on day 16 BOD value is 5.022mg/L. It shows that the mean (Mean) BOD decreased from the initial concentration of 20.029 at 0 days to 5.555 at 16 days treatment. On the 16th day the efficiency value of setting aside BOD levels is 72.3%, on day 0 the TSS result is 85 mg/L until the repetition (Y1) on the 16th day the BOD result becomes 28 mg.L and the second repetition (Y2) on day 0 TSS result 83 mg/L until repetition (Y2) on day 16 the result TSS value 26 mg/L. Then the mean value (Mean) of TSS decreased from the initial concentration of TSS value of 84 mg/L on treatment day 0 and became 27 mg/L. on 16 days of treatment while for TSS levels that is equal to 67.86%.

Abstract

Saat ini, krisis air bersih mulai dirasakan masyarakat, khususnya masyarakat kota. Untuk itu, solusiyang harus dilakukan adalah penggunaan air yang efisien dan mendaur ulang limbah dari buanganair limbah industri merupakan alternatif yang terbaik. Hasil analisis pengelolaan air limbah domestikdi IPAL PT Komatsu Indonesia ternyata beberapa parameter air buangannya tidak memenuhipersyaratan air bersih, sehingga perlu ditambahkan unit pengolahan lainnya yaitu penambahanrecycle unit yang terdiri dari filter zeolit aktif, filter karbon aktif, filter bag dan ultrafiltrasi.Berdasarkan penelitian yang telah dilakukan, dapat disimpulkan bahwa dengan menggunakanrecycle unit dapat menurunkan beberapa parameter air limbah yaitu TDS, zat organik, besi danmangan dalam air limbah. Perbandingan hasil analisa air effluent dengan analisa air PAM dapatdisimpulkan bahwa air beberapa parameter air effluent hasilnya lebih baik dibandingkan parameterair PAM, parameter tersebut adalah pH, zat organik dan besi.
