Abstract

PT Tirta Investama Pabrik Mambal merupakan industri yang bergerak di bidang produksi Air Minum Dalam Kemasan (AMDK) di Desa Mambal, Kecamatan Abiansemal, Kabupaten Badung, Provinsi Bali. Dalam kegiatan industry pengolahannya telah dilengkapi dengan dokumen lingkungan yaitu AMDAL sekaligus membangun IPAL (Instalasi Pengolahan Air Limbah) untuk mengolah limbah hasil produknya. Tujuan penelitian ini untuk menganalisis tingkat efisiensi air melalui upaya penghematan pemakaian air bersih, melakukan konservasi air dan menjaga ketersediaan sumberdaya air dan dan penurunan beban pencemaran dengan kegiatan TSS, BOD 5, minyak dan lemak, dan debit air limbah. Hasil penelitian menunjukkan bahwa perusahaan ini telah memenuhi kriteria efektivitas dengan hasil rata-rata yang tidak melebihi standar baku mutu yang sudah diterapkan dalam Peraturan Gubernur Provinsi Bali No 16 tahun 2016 melalui program kegiatan 3R Air berhasil mencapai angka 25% dalam tingkat efisiensi air mulai dari proses pengolahan air hingga pengemasan produk kemasan 5 galon (HOD), terhadap total produk dengan intensitas pemakaian air tahun 2018 sebesar 1,22 m3 dan berhasil melakukan penurunan beban pencemaran air sebesar 2,43 gCOD/Ton Produk tergolong pada 25%. Hal ini karena terjadi perubahan sistem IPAL yang tadinya dibuang ke sungai dan tidak dimanfatkan, ditampung kemudian disalurkan ke toilet untuk air domestik. Dengan demikian program keberlanjutan sumber daya air telah berjalan optimal.

Abstract

Botol PET (Polietilena Tereftalayt) memiliki Softening point lebih rendah yaitu 140oC dibandingkan dengan botol PC (Polycarbonate) yaitu 200 oC, maka diperlukan pengkontrolan suhu pencucian botol yang lebih rendah dan lebih stabil. Kontrol Proportional, Integral, Derivative (PID) adalah sistem pengendali yang umum digunakan di industri dengan respons waktu yang cepat dan lebih stabil dari hysterisis. Inisiatif penghematan energi dengan cara mengurangi lekukan perpipaan juga dapat dilakukan. Kelebihan jumlah lekukan perpipaan akan mengakibatkan menurunnya tekanan air penyemprotan pada ujung nozzle, kondisi ini memaksa penggunaan daya pompa yang lebih besar untuk mendapatkan besaran tekanan yang sesuai dengan parameter pencucian. Masa air juga berpengaruh besar terhadap kebutuhan energi untuk pemanasan di tangki mesin pencuci botol. Semakin banyak masa air, maka semakin besar pula energi listrik yang dibutuhkan untuk mencapai suhu acuan. Penelitian ini dilakukan pada mesin pencuci botol 5 gallon, dengan mencatat parameter-parameter washer, terutama suhu dan konsumsi energi listrik harian. Dari hasil penelitian didapat penurunan deviasi suhu dari 6o celsius menjadi 1 oC. Indeks rata-rata konsumsi energi listrik sebelum inisiatif adalah 112,63 kwh/kbtl (kilowatt hours/killo bottles) sedangkan indeks konsumsi energi rata-rata setelah inisiatif adalah 87,09 kwh/kbtl.

Abstract

Starting from a problem in the process of lubricating the conveyor motor using a grease gun manually which is done manually, so there will always be grease/lubricant overflow which is finally wiped using a cloth cloth. The rags that have been contaminated by this grease will become B3 Waste (Hazardous and Toxic Waste) which will be high. The lack of automatic equipment facilities requires employees to perform manual processing, this of course causes productivity and product quality to be less than optimal. Conveyor designer through modification of lubricant cartridge as automatic lubricant. Modify the lubricant cartridge so that it is able to lubricate automatically with a timer. Thus, the lubrication process for the motor conveyor axle can be carried out with precision and order, so that there is no longer any spillage of grease/lubricant that must be wiped with a cloth. This can eliminate one of the sources of B3 Lap Majun waste. This resulted in a decrease in the overall B3 Waste Load. With this system, it can reduce the burden of Hazardous and Toxic Waste, especially from contaminated cloth, by 0.04 tons/year.

Abstract

Compressors and compressed air systems are important areas for improving energy efficiency in industrial plants. The compressor engine is one of the machines that are included in the top 5 machines with the highest energy consumption. Based on the results of the analysis, the old compressor with a capacity of 90 KW only had a load of 70%, so another 30% wasted energy during the unload condition. The compressor engine which previously used high enough energy was replaced with a compressor engine type AF OPC 55-10 which uses more energy efficiently than the previous type because its capacity is only 55 KW. Through the use of this compressor, the compressor load can reach 90% and is more efficient in energy use. Thus, the potential for energy savings from the utilization of the compressor engine, reaches 306,600 kwh/year. or a potential cost savings of Rp. 442,945,020 per year. With a temperature of 50oC when operating (load) the motor output power is 193 KW and when not operating (unloaded) at a temperature of 45oC the motor output power is 186 KW from the nameplate data of 200 KW. The percentage of leaks in the compressed air system on the blow molding machine is > 10%.

Abstract

In its implementation, to monitor water discharge to the water treatment section, a flowmeter is used to obtain water discharge results, and an ultrasonic sensor is also added which is connected to the controller which produces height data. Furthermore, water level data, water discharge data and cost rates for water pump motors will be displayed via the website for remote control systems because of the speed of data transmission, efficiency and wide coverage. However, it still needs to be connected to a control device to be able to monitor electrical devices remotely. The research objective is to design an integrated automation pump as an energy saving alternative. The research method using integrated automation pump design using a picobox is power supply circuit design, AC current sensor circuit design, RTC circuit design, and microcontroller circuit design. Based on the research results, based on the results of testing the use of the Lambda Iteration method which is commonly used in economical operations of electric power systems, it turns out that it can also be effectively applied in economical operations using water pump motors. From the results of the calculations that have been carried out, the optimal water pump motor operation scheduling is in the 10th iteration calculation, with the calculation results that the first water pump motor must pump a volume of 59 m3. This scheduling also has an impact on reducing the operating costs of the pump motor which is estimated in one filling cycle to Rp. 6,214,- in one filling cycle. The total energy efficiency of this innovation is 11,880 Kwh/year with cost savings of Rp. 13,068,000. This means that the Lambda Iteration method is able to reduce costs by 34.1%.

Abstract

The need to use plastic as packaging material for food and beverages still has great opportunities. In the process of making packaging bottles, a machine called blow molding is required. The aim of this research is to design photo rejector preforms for injection blowing tools installed on blow molding machines that must have high strength so that they are able to support the load of the injection tools and mold cavity in an effort to deal with non-b3 waste. The research method uses the Six Sigma method to reduce defects based on the RPN (Risk Priority Number) value. Based on the research results, there are several types of defects that occur in the 2000 ml ASB blow molding machine, namely: runner defects, preform defects, and bottle defects. The 2000 ml defective bottle has the three highest causes of defects, namely: the absence of standards for machine startup with an RPN value of 448, components exceeding the useful life limit with an RPN of 378, and the absence of machine checking standards with an RPN of 336. The total production cost is more efficient at IDR 8.700.000. Thus, the total reduction in non-B3 waste from this innovation in 2022 will be 1.94 tons. This can reduce environmental damage significantly.
