Abstract

Darurejo Village, Plandaan District, Jombang is an onion horticulture area where the highest productivity level is in the Jombang Regency of 3990 kw and 38 kw/ha. However, the onion sales are not optimal so farmers often experience losses. Therefore, we service activities regarding the processing and management to enhance the effectiveness. Coinciding with the COVID-19 pandemic and the enactment of the government's decision to Implement Emergency Community Activity Restrictions (ECAR) the implementation of counseling is carried out online. The online activity was carried out through the WhatsApp Group, on Saturday, July 31, 2021, from 11.00-14.00 WIB, which was attended by 25 village cadres. This outreach activity was carried out by providing 2 materials, including basic knowledge of onion and the resulting products such as fried onion, onion baceman, and onion powder which have great potential to be widely sold, and the introduction of automatic peeling machines to increase the quantity and quality of productions through online and offline meeting on August 28, 2021. It is hoped that the community will be able to process and manage the onion shallot potential products.

Abstract

The simple organic waste processing in this journal is a follow-up to the previous activities. By using a concise method that did not take up land, the people of Gebang Putih Village have been able to process simple organic waste into ready-to-use compost. The method used in making ready-to-use compost was to stack brown and green waste in layers and then doused it with two variations of bio-activators, i.e., leri water (rice washing water) and EM4. After the 18th day, the resulting fertilizer showed dry characteristics, odorless, and had a neutral pH. An interesting result in this study was that the compost with the addition of leri water (pH=7) began to decompose on the 9th day. However, in the compost with the addition of EM4, on the 6th day, the compost had decomposed evenly. However, the final results of the compost produced proved that leri water was quite effective as an alternative bio-activator, a substitute for EM4.

Abstract

The midsole is an inseparable component of the shoe. For this reason, midsole production must be fulfilled so that the needs of shoe manufacturers to produce shoes can be met according to the target. Midsole Jepara factory is one of the work units of PT. X is a company that processes Compound raw materials into Midsole as its main product. ISO 9001:2008 is an international standard for quality management systems. ISO 9001:2008 establishes requirements and recommendations for the design and assessment of a quality management system. It is expected that the products produced from an international quality management system, will be of good quality (standard). Based on this, this study will discuss the quality assurance contained in a manufacturing company to prevent the absence of things that cause product defects. In analyzing the implementation of ISO 9001:2008 used is the analysis of P control maps, fishbone diagrams, and Pareto diagrams. In controlling the midsole products it produces, PT X applies a policy regarding product quality standards, namely using the PDCA (Plan Do Check Action) quality standard.

Abstract

XYZ Village is an industrial village that produces woven fabrics. Failure in the production process is something that must be traced to the cause so that it can be used as a basis for improving product quality. Total Quality Management (TQM) is an approach to running a business that tries to maximize the competitiveness of an organization through continuous improvement of products, services, people, processes, and the environment. This study was conducted to identify potential causes of failure and improve the quality of woven fabrics in the weaving process in XYZ Village with the TQM method approach. Based on the calculations that have been done, it was found that there are two valid variables and two other invalid variables because the value of r-count > r-table, namely the variable color is less bright and the color is mixed. Then the main factors that cause the quality of woven fabrics to decrease and result in production failures on woven fabrics are inappropriate battens and also color spots on woven fabrics.

Abstract

Mesoporous silica is continuously raising in popularity due to its excellent and unique properties, such as customizable pore, surface shape/morphology, large pore volume, and ease of functionalization for wide applications like catalysis, energy, environment, and biomedical areas. In the templated growth synthesis, a template acts as a mesostructure-directing agent to produce hollow porous structures in silica frameworks. Templates can be divided into "hard" and "soft" templates. While soft templates are typically in a fluid-like condition and hard templates are typically solid-state materials with specific morphology and structure. In this minireview, we summarize the synthesis method of mesoporous silica with a soft-hard template approach (template-assisted method).
