Abstract

One of the plantation companies and palm oil mills in West Sumatera is part of the group and makes a positive contribution. In one of the palm oil factories in West Sumatra, there is a problem with the flow of the work process, where there is an accumulation of products of different sizes in the factory area. This hinders the product transfer process. In addition, this situation will affect the use of the land area. Therefore, it is necessary to consider how to make or change the layout of facilities more effectively and efficiently. An activity Relationship Chart will be used as a method to make recommendations for the layout design of palm coconut factories. The flow of the crude palm oil production process from the proposed layout design weighs the car and bunches of fresh fruits before heading to isolation until the bunches of ripe fruits are stored in the storage tank before being transferred to the transport car. Based on the proposed layout redesign, the management of the oil palm mill can consider improving the placement of the area in the boiler station, as well as the placement of production not too far from the production process.

Abstract

Industri pengolahan crumb rubber di Sumatera Barat memiliki operator trolley sebagai bagian dari pekerjanya. Saat ini, analisis lama waktu istirahat berdasarkan beban kerja operator trolley belum pernah dilakukan oleh perusahaan. Berdasarkan hasil observasi yang dilakukan secara langsung menggunakan kuesioner Nordic Body Map (NBM), lebih dari 50% operator trolley yang bekerja mengalami keluhan pada bagian kaki. Sehingga dilakukan analisis lama waktu istirahat berdasarkan beban kerja operator trolley dengan pendekatan fisiologis pada crumb rubber industry di Sumatera Barat. Penentuan waktu istirahat berdasarkan beban kerja menggunakan metode tidak langsung dengan menghitung denyut nadi selama bekerja serta metode langsung dilihat melalui asupan oksigen selama bekerja. Berdasarkan hasil pengukuran beban kerja, menggunakan metode pengukuran tidak langsung, didapatkan %CVL pada pekerja proses pembongkaran trolley meningkat mencapai 58,81% sehingga diperlukan perbaikan. Pada rata-rata P1, P2, P3 pekerja pembongkaran trolley adalah 88,6 atau mempunyai nadi pemulihan normal dan beban kerja tidak berlebihan (not excessuve). Untuk hal tersebut perlu dilakukan pengkajian lebih lanjut. Pada pengukuran menggunakan metode pengukuran langsung, total metabolisme yang didapat sebesar 206,86 Kkal/jam dengan beban kerja tergolong sedang. Berdasarkan pendekatan fisiologis untuk penentuan waktu istirahat menyatakan bahwa tidak dibutuhkan waktu istirahat tambahan selama melakukan kerja pada proses pembongkaran trolley tersebut (Rt = 0).

Abstract

One of the companies that make tools for printing at one of the printing companies in Jakarta has a product in the form of Offset Roller Printing, where Offset Roller Printing is a mainstay product with the highest sales. The company promises a declining trend in the rejection rate in 2024, with the rejection rate not exceeding 2%. For that, an analysis of the cause of the problem will be carried out until a repair proposal is obtained by using an integrated method which is Statistical Quality Control (SQC) with Failure Mode Effect Analysis (FMEA). Based on the check sheet, it shows the total production in January - December 2023 of 5699. On the overall operational map, there is no point that is outside the upper or lower operational limits. From the results of the FMEA analysis, it can be seen that the highest RPN is the cover for the method factor with the first priority having an RPN value of 252 which means that the vulcanization temperature is not reached or the temperature of the maturity point is not reached. unable to. There is a need to renew the vulcanization recipe so that the rubber matures perfectly and avoids the occurrence of oblong or closed defects. In addition, improvement proposals as a form of evaluation results are given related to the operator's attention factor, operator's skill, various types of materials, working environment temperature, no machine control, comfortable work environment, hostap plastic setting.

Abstract

Penggunaan biopelet di Indonesia saat ini masih tidak banyak, meskipun sumber daya biopelet di Indonesia, khususnya di pulau Sumatera, sangatlah banyak dari berbagai variasi sumbernya, seperti limbah dari industri perkebunan, pertanian, dan lainnya. Dalam aplikasinya, biopelet yang berasal dari kayu dan non-kayu maupun kombinasi keduanya dalam penentuan proses yang menggunakan Design Expert metode Mixture D-Optimal merupakan sesuatu yang terbarukan. Penelitian ini bertujuan untuk mendapatkan proses yang optimal pada produk biopelet berbahan pelepah kelapa sawit dengan penambahan limbah serbuk kayu menggunakan Design Expert 13.0, kemudian dilakukan standarisasi proses produksi terhadap produk biopelet berbahan pelepah kelapa sawit dengan penambahan limbah serbuk kayu. Berdasarkan hasil terhadap respon yang telah ditentukan, yaitu kadar air, kadar abu, dan nilai kalor terhadap biopelet, terdapat biopelet dengan variasi proses yang memenuhi kriteria SNI 8021–2014 Persyaratan Pelet Kayu dan SNI 8675–2018 Persyaratan Pelet Biomassa. Proses optimal terpilih pada produk biopelet berbahan pelepah kelapa sawit dengan penambahan limbah serbuk kayu berdasarkan Design Expert 13.0 adalah dengan ukuran partikel 40 mesh dan temperatur pengovenan 120°C yang memiliki nilai desirability 0,953.

Abstract

Developing hard candy as a functional food with antioxidants and antibacterial properties derived from natural ingredients will do. By analyzing the formulation of innovations and analysis of the financial viability of hard candy products with the addition of gambir catechins, it is expected to provide information to stakeholders related to the development of hard candy innovation products with the addition of gambir catechins (Uncaria gambir Roxb.). The results of the analysis of organoleptic tests, obtaining formulas 17, 8, 18, 4, 7 hard candy had the rating respondents liked very much (4-5). Then conduct a quality test based on SNI hard candy 3547.1:2008 on products that have the criteria of organoleptic test results. Results from SNI hard candy test 3547.1:2008, the product met the standard requirements of SNI 3547.1:2008 products. When compared to hard candy products on the market with an average selling price of around Rp. 333.33, the hard candy products in this study can compete, especially strawberry variants. On a production scale of at least, 10 kg of hard candy HPP can compete with other products, where the hard candy in this study has a high added value antioxidant and has antibacterial properties useful for the health of consumers.
