Judul: Energy Audit and Productivity Optimization of Stretch Blow Moulding Machine for PET Bottle Cap Production at PT. Sari Multi Utama
Abstrak: PT. Sari Multi Utama (SMU) merupakan salah satu perusahaan yang memproduksi botol plastik jenis PET (Polyethylene Terephthalate). Salah satu kendala yang dihadapi adalah penentuan kinerja serta penggunaan energi secara akurat pada mesin stretch blow moulding (CPSB CSS 3000). Perawatan mesin yang dilakukan oleh PT. SMU hanya menggunakan metode korektif yang berdampak pada waktu downtime yang tinggi dan rendahnya produktivitas. Penelitian ini bertujuan untuk melakukan analisis downtime mesin, analisis kebutuhan energi dan optimalisasi kinerja mesin dengan metode perawatan preventif dan korektif. Hasil analisis menunjukkan rata-rata penggunaan energi listrik dan manusia saat dilakukan perawatan secara korektif sebesar 33.758,13 kWh, setelah dilakukan perawatan secara preventif dan korektif turun menjadi 29.432,74 kWh. Energi spesifik produk turun dari 0,025 kWh/pcs menjadi 0,022 kWh/pcs. Produktivitas mesin sebelumnya sebesar 97% dan setelah dilakukan perawatan preventif dan korektif meningkat menjadi 99%. Total downtime mesin dapat diturunkan dari sebelumnya 14,3 jam menjadi 4,9 jam. Tindakan perawatan secara preventif dan korektif pada mesin CPSB CSS 3000 mampu menurunkan downtime hingga 65,73 % dan meningkatkan produktivitas mesin hingga 2,06 %., PT. Sari Multi Utama (SMU) is one of the companies that produces PET (Polyethylene Terephthalate) type plastic bottles. One of the obstacles faced is the determination of performance and accurate use of energy in stretch blow moulding machines (CPSB CSS 3000). Machine maintenance carried out by PT. SMU only uses corrective methods that have an impact on high downtime and low productivity. This study aims to analyze machine downtime, analyze energy needs and optimize machine performance with preventive and corrective maintenance methods. The results of the analysis showed that the average use of electrical and human energy when corrective treatment was carried out 33,758.13 kWh, after preventive and corrective treatment decreased to 29,432.74 kWh. Product specific energy rose from 0.025 kWh/pcs to 0.022 kWh/pcs. The productivity of the previous machine was 97% and after preventive and corrective maintenance was carried out increased to 99%. The total engine downtime can be lowered from the previous 14.3 hours to 4.9 hours. Preventive and corrective maintenance actions on the CPSB CSS 3000 machine are able to reduce downtime by up to 65.73% and increase machine productivity by up to 2.06%.

Judul: Kajian Peluang Aplikasi Produksi Bersih Untuk Meningkatkan Efisiensi Produksi Teh Botol Sosro (Studi Kasus di PT. Sinar Sosro KPB Cibitung)
Abstrak: Teh Botol Sosro (TBS) is one of the main products of tea processing in PT Sinar Sosro KPB Cibitung. The total production efficiency was influenced by efficiency in the water treatment process unit, extraction process unit, mixing process unit, and bottling process unit. TBS production efficiency in 2011 was 58.24% with total production of 228 129 672 bottles. The efficiency continuously decreased in 2012 and 2013 at 57.08% and 56.35% with total production of TBS 271 265 184 bottles and 246 664 944 bottles, respectively. The decrease of production efficiency was affected by machines performance. The purpose of this study was to analyse the opportunity for cleaner production implementation and to formulate its alternative strategy for improving the efficiency of TBS production process. The methods used in this study were quick scan on the production process of TBS, and implementation feasibility assessment. The result from quick scan showed that inefficiency of TBS production occured in some unit processes, namely water treatment process unit, extraction process unit, mixing process unit, and bottling process unit. The inefficiency of production with respect to the highest breakdown time were the bottle washing process unit and fillercrowner process unit. Alternative strategies of cleaner production recommended are implementation of good operating practices, the use of control level sensors for the extraction tank and mixing tank, good maintenance of bottle washer units and liquid sweet tea (TCM) filling units of as a preventive action. Result of the feasibility assessment and the highest frequency (modus) of breakdown time, it is recommended the priority for implementation of cleaner production in the the bottle washing machine maintenance system.
