Abstract

Quality is a benchmark to determine the level of good and bad of a product. The level of quality of a product will affect customer satisfaction, hence, to produce high quality products, it is necessary for a company to have a quality control process. Quality control is a process that aims to maintain the quality of products and services that have been promised to consumers. In this study, quality control is carried out in the sugar packaging process. Where in the sugar packaging process found the resulting product has a poor quality, defective and not in accordance with specifications. This study uses the Statistical Process Control (SPC) method which aims to determine the causes of defective products with the intention that the packaging process can further minimize the level of product defects. The SPC method is a statistical analysis technique with seven statistical tools or seven tools. Based on the results of the study it can be seen that the cause of product damage / defects in the product packaging process is caused by three types of damage namely damage due to conveyor (38.17%), damage due to machine pinched (35.82%), and damage due to loose seams (26,00%) This type of damage can be caused by human error and other factors such as engine condition, engine cleanliness and the monitoring process. Proposed improvements recommended for the company are to provide training to employees, make clear work instructions, conduct periodic maintenance for the machines used, supervise all work areas, and carry out quality control for every acceptance of raw materials.

Abstract

Stunting merupakan gagal tumbuh dari anak yang ditandai dengan tinggi badan yang lebih pendek dari usia seharusnya. Kegagalan tumbuh akibat kekurangan gizi kronis. Salah satu upaya untuk menurunkan kasus stunting adalah peningkatan peran posyandu  dengan pelatihan stunting dan penerapan teknologi dalam penatalaksaan stunting di Desa Pakem. Kegiatan dilaksanakan dengan memberikan pelatihan dan demontrasi dari proses pelatihan stunting. Kegiatan dilakukan di Desa Pakem, Kecamatan Sukolilo Kabupaten Pati pada Tanggal 8-15 November 2025. Analisa pelatihan stunting dan penerapan E-TOS dari nilai rata rata 45,55 setelah dilaksanakan 67,67. Sedangkan dari kertercapaian dalam kegiatan didapatkan nilai sebesar 90 %. Ketercapaian ini didasarkan dari ada beberapa kader yang tidak memiliki alat komunikasi dalam pelaksaaan evaluasi kegiatan pelatihan stunting.  Analisa pelatihan kegiatan pengolahan bahan makanan dari makanan local  dari nilai rata rata 65,45 setelah dilaksanakan 72,33. Sedangkan dari kertercapaian dalam kegiatan didapatkan nilai sebesar 100 %. Penerapan e-TOS memberikan dampak positif berupa tersedianya gambaran spasial dan visualisasi data yang lebih informatif, yang memudahkan analisis wilayah rawan stunting dan pengambilan keputusan berbasis bukti.

Abstract

The increasing volume of global plastic waste, which has exceeded 367 million tons per year, has created a serious environmental problem, particularly in Indonesia, which contributes about 17% of the national waste. Mechanical recycling and direct incineration are considered less optimal due to limited product quality and potential pollution. As an alternative, pyrolysis offers a promising technology to convert plastic waste into liquid fuel (pyrolysis oil) with characteristics similar to conventional fuels. This study utilized even-numbered plastic wastes (HDPE, LDPE, PS) through pyrolysis at 300 °C for 45 minutes with a reactor capacity of 5 kg, producing 1 L of pyrolysis oil per batch. Characterization results indicated that most fuel parameters met ASTM standards, such as Total Acid Number (0.02 mg KOH/g), flash point (61 °C), and sulphur content (0.005%), although some deviations were found in water content, carbon residue, and cetane number. To improve its quality, 0.2% solketal was added as an oxygenated additive, which significantly enhanced engine performance and reduced emissions. Performance testing using a D-4D diesel engine demonstrated improved fuel efficiency, while emission tests showed lower opacity and CO levels, along with more complete combustion indicated by higher CO₂ emissions. These findings confirm that integrating pyrolysis with solketal additives can produce a more efficient, environmentally friendly alternative fuel with potential for application in sustainable energy industries.
