Abstract

XYZ is a company that produces gloves. Due to the resulting defects such as vague logos, slanted stitching, mold and loose stitching, the company needs to make quality improvements so that defects become 0%. The aim of this research is to carry out quality control using the Six Sigma and FMEA methods to determine the sigma value and determine the causes of defects and make recommendations for improvements to the highest defects. From the results of Six Sigma calculations, a sigma level of 3.6 was obtained, which means that it is sufficient and 197,300 defects can occur on a production scale of one million. The capability results with an average value of 1.15 indicate that it is only quite reliable on a scale of 1-2. FMEA shows the highest cause of failure is sewing machine jams which can cause skewed stitches. The recommended control plan is to carry out routine weekly machine maintenance. Common factors causing defects are lack of regular maintenance on production machines, worker negligence, worker fatigue due to hot weather, lack of strict supervision of workers during the production process, less skilled workers and humid air temperatures resulting in moldy gloves. Proposed improvements in overcoming defects include carrying out routine maintenance on all machines, carrying out strict supervision of workers, implementing SOPs with strict supervision, adding air conditioning facilities, and adding a sterilization process for finished glove products.

Abstract

Katumbangan Village is one of the villages in Campalagian Subdistrict that has soil fertility and a good rainfall climate supported by evenly distributed plant vegetation growth, making places like this very suitable for beef cattle farming. One of the innovations given to farmers in the prevention and handling of diseases is by providing herbal supplements as additional feed for livestock. Herbal supplements are a type of additional supplement given to livestock whose basic ingredients are made from herbs and spices.  The socialisation and demonstration activities on making and giving herbal supplements to ruminants are expected to make it easier for farmers to handle and prevent diseases in livestock through herbal supplements. The methods provided consist of: 1. socialisation or presentation of material on efforts to handle and prevent diseases through herbal supplements. 2. training and technology application is a hands-on demonstration on making herbal supplements. 3. monitoring and evaluation through pretest and posttest. The results of the implementation of community service increased the knowledge of farmers about the types of diseases, handling and prevention of diseases before training only 12% and after training there was an increase of 91%. Meanwhile, farmers' knowledge of herbal supplements before the community service activities from not knowing to 95%. In addition, there was an increase in farmers' knowledge about kitchen spice ingredients that can be used as herbal supplements for livestock. The use of herbal supplements to reduce the use of antibiotics that can cause resistance. This activity went very well as evidenced by starting from the socialization of farmers actively involved, training activities farmers also actively helped in making herbal supplements and there was an increase in knowledge from before the activity and after the activity.

Abstract

Fertilizer is one of the strategic elements that plays a role in increasing productivity and unity part of the farming system. The current difficulty for farmers is the scarcity and inaccessibility of fertilizer subsidies, forcing them to seek alternatives to reduce fertilizer purchase costs. An alternative that can be used with organic fertilizer, which can be made using cow dung and aren plant waste, is bokashi fertilizer. The purpose of implementing this Community Service Program is to provide information related to technological innovations in processing aren waste and animal manure as organic fertilizer/compost to increase farmers' income and its application on plants. The implementation method of the activity includes preparation such as location surveys, discussions and explanations on bokashi fertilizer production, outreach and training through material presentation and demonstrations/practice on how to make bokashi fertilizer, as well as monitoring and evaluation. The results of the activity show a significant increase in knowledge and skills among the Bukit Harapan farmer group participants. Before the implementation of the community service activity, the partners' knowledge of waste processing as organic fertilizer was only 4.43%. After the community service activities, the partners' skills increased to 92.29%. The results of the mentoring for the Bukit Harapan Farmers Group were successfully achieved. This is evident from the bokashi, which is mature, has a dark color, a fine texture, and is odorless.

Abstract

This PkM activity is carried out in the context of spiritual formation for groups in the categories of children and adults. One of the focuses is serving children creatively. This is necessary because children's services experience problems in various churches, due to a lack of human resources, but also a lack of creativity in children's services which has an impact on reducing children's interest in attending worship services. These concerns prompted the STT ATI team to carry out PkM activities as a way to overcome them. The activity was carried out at GPPIK "Bukit Torsina" Runut, Landak Regency, West Kalimantan. The methods used in this PkM activity are stories, movements and songs, games, creations, and sermons or lectures. The results of this activity show that the activity had a good impact on the congregation and received a positive response from the local church. Apart from that, children learn new things through creative children's services. Services in the adult category also received a good response.

Abstract

Dengue remains a major global health concern, with current licensed vaccines offering variable protection across the four virus serotypes and posing safety considerations related to antibody-dependent enhancement (ADE). To contribute toward improved vaccine design, we developed a bivalent virus-like particle (VLP) targeting DENV-1 and DENV-2, the two most prevalent serotypes in Indonesia. Consensus envelope (CE) protein sequences from Indonesian DENV-1 and DENV-2 strains were codon-optimized and co-expressed in Pichia pastoris GS115 using the AOX1 promoter. The expressed proteins were solubilized from membrane fractions under denaturing conditions, purified via Ni2+-affinity chromatography, and subjected to urea gradient dialysis for VLP assembly. Transmission electron microscopy confirmed the formation of spherical VLPs. Western blot analysis confirmed expression and purification via anti-His detection, and supported antigenic integrity of the envelope proteins as recognized by anti-dengue E antibodies. The study demonstrates the feasibility of using P. pastoris for chimeric dengue VLP production based on regionally relevant strains. The findings support the development of serotype-focused VLP platforms as modular components in the development of future tetravalent dengue vaccines.
