Abstract

Hasil observasi di PT. Holcim Indonesia Tbk, pabrik Cilacap, didapati banyaknya pemborosan di bagian pengepakan semen, termasuk banyaknya produk cacat kemasan, sehingga banyak semen tercecer dan harus mengulangi proses pengepakan. Penelitian ini dilakukan untuk mengidentifikasi pemborosan selama proses pengepakan menggunakan  pendekatan lean manufacturing dengan value stream mapping. Sementara tingkat kualitas dianalisis dengan metode six-sigma. Penyebab kecacatan produk dianalisis dengan fish-bone diagram. Failure Mode and Effect Analysis (FMEA) digunakan untuk merancang ususlan perbaikan. Pemborosan yang teridentifikasi meliputi : transportation, motion, waiting, over processing, dan defect. Usulan perbaikan untuk mengurangi pemborosan yaitu dengan penggabungan stasiun penimbangan dan stasiun pemeriksaan, sehingga memberikan estimasi peningkatan  process cycle effisiensi  dari 39,1% menjadi 46,69. Sedangkan upaya untuk mengurangi cacat produk dilakukan dengan perawatan preventif mesin packer.

Abstract

The“Bersih Bersama” Waste Bank located in Karanganom, Sitimulyo, Piyungan, Bantul, Yogyakarta Special Region was a waste bank that still exists to manage waste from the local community. The problems faced include that management ware still limited to receiving from customers, then collected and handed over to collectors. The customer was not always doing the sorting process, so the managers have to sort and even have to clean it first. In addition, the level of community awareness to manage waste is still lacking. The purpose of community service was to provide additional skills to members of the waste bank to convert used goods that were originally only sorted and sold, converted into products that have use value and sale value. Community service activities were carried out by organizing training and assistance in making coffee sachet bags using waste paper and coffee sachets (plastic) directly to the community. This training was carried out in 2 stages, namely on September 20 for stage 1 and October 10, 2020 for stage 2. The results of the implementation of community service were increased knowledge about the use of paper and plastic waste, the ability to make new products in the form of coffee sachet bags with attractive motifs that have value. added. A positive impact can be seen from the increased knowledge and understanding of waste bank members in the use of paper and plastic waste into useful and economic goods. In addition, the Karanganom Sitimulyo community can contribute to reducing plastic waste in their environment

Abstract

Diantara produk yang banyak dikonsumsi masyarakat yang berpotensi besar merusak lingkungan adalah popok sekali pakai karena komposisi bahan yang sulit terurai di alam seperti plastik dan Super Absorbent Polimer (SAP). Popok kain ini dianggap lebih ramah lingkungan. Hanya saja jumlah pengguna popok sekali pakai tetap lebih banyak, khususnya di daerah berkembang seperti Kabupaten Bantul. Untuk itu dilakukan penelitian yang bertujuan untuk mengetahui faktor yang berpengaruh terhadap niat penggunaan popok ramah lingkungan ini. Faktor yang diteliti adalah:  sikap terhadap penggunaan green product, norma subyektif, perceived behavioral control, kepedulian terhadap lingkungan, perceived risk, dan personal norm. Pengolahan data dielakukan dengan regresi berganda. Dari hasil penelitian diperoleh fungsi regresi: Niat= 0,058sikap + 0,284SN + 0,390PBC + 0,032KL – 0,026PR + 0,118Norm. Berdasarkan uji t didapat kesimpulan bahwa faktor yang signifikan berpengaruh adalah perceived behavioral control, norma subyektif, dan personal norm.

Abstract

Waste is one of the problems in Bantul Regency, especially in Bangunjiwo Village, Kasihan District. Bangunjiwo Village has a waste generation of 8.39 tonnes per day, but only 0.03 tonnes can be managed, and the rest is disposed of in landfills. The contributing factors are low public awareness of waste management and suboptimal waste management. The purpose of this study is to propose a waste management strategy to reduce the volume of waste disposed to landfill. This research uses the SWOT method as a strategy planning tool by considering the internal factors of the waste management party and the external factors that surround it. Strategy determination is based on the calculation of the IFAS and EFAS matrix which serves to determine the quadrant position. Then the quadrant position is used as the basis for determining waste management strategies. The results showed that the position of waste management in Bangunjiwo Village is in quadrant 1 (S-O), which means that it must optimise internal strengths and existing opportunities. The strategy formed is a strategy of collaboration between BUMDes and private waste collectors by utilising funds provided by the Regency Government and utilising the existing large land area, as well as increasing the empowerment of Human Resources (HR) for waste management.

Abstract

The waste bank is one of the methods used by the Government of Sleman Regency, DIY, to solve the waste problem. However, citizen participation to be active as customers in the waste bank is still lacking. For this reason, a study was conducted to find out what factors affect the level of activity of citizens in depositing waste into the waste bank. The research uses The Theory of Planned Behavior, coupled with factors: knowledge of how and what and knowledge of consequences. Data was collected through interviews with several bank administrators and customers and filling out the questionnaire. Respondents were selected by purposive sampling from 11 waste banks. The analysis method uses multiple linear regression by testing the significance of the regression model, the coefficient of determination, and the partial effect test of each variable. The results showed that attitudes, subjective norms, contr, knowledge of how and what, and knowledge of consequences simultaneously affected 73% of the intention. Among the five independent variables, only the perceived behavioral control has no partial effect. The study also showed that the intention had a significant effect on the waste bank's active behavior with a coefficient of determination of 63%.

Abstract

The increasing volume of waste in Bantul Regency is a problem that must be solved. One of the things that the Regency Government does is by promoting waste banks. From the existing waste banks, citizen participation is still low, so it is not significant enough to reduce the volume of waste disposed of at the Piyungan landfill. One of the factors identified is the low interest of residents to join the waste bank. For this reason, a study of citizens' behavior is needed so that they join the waste bank with a theory of planned behavior coupled with knowledge of how and what and knowledge of consequences factors. Data collection was carried out by distributing questionnaires to members of the garbage bank. The number of respondents was 1265 from 29 waste banks spread throughout Bantul Regency. The method of data analysis uses linear regression. Research shows that attitudes, perceived behavioral control, knowledge of how and what, and knowledge of consequences have positive and significant effects, both simultaneously and partially, on the intention of residents to join the waste bank. Intention is also a significant positive and significant effect on behavior.
