Abstract

AbstrakTerdapat beberapa jenis limbah kayu dari hasil proses produksi diantaranya adalah limbah serbuk kayu limbah serutan kayu, limbah serpihan kayu, dan limbah potongan kayu. Berbagai upaya dilakukan untuk memberi nilai tambah pada setiap jenis limbah kayu tersebut diantaranya adalah pembuatan kayu laminasi, kayu partikel, MDF, HDF, briket kayu, ornamen kayu, dan lain-lain. Program pengabdian ini memanfaatkan limbah potongan kayu jati menjadi produk papan kayu laminasi dan bekerja sama dengan kelompok industri meubel rumahan Desa Mangunsari di Kabupaten Semarang. Kelompok industri tersebut memiliki limbah-limbah kayu berbagai jenis dengan kuantitas yang tergolong melimpah namun belum ada perlakuan (treatment) sama sekali terkait limbah tersebut selain hanya dimanfaatkan untuk memasak dan dibuang ke lingkungan. Edukasi dan pelatihan dilakukan melalui program ini untuk membantu mitra dalam membuat limbah kayu jati menjadi papan kayu laminasi dengan memanfaatkan alat kerja seperti table saw, hand planner, hand sander, lem kayu, dan bar clamp. Poin penting pembuatan papan kayu laminasi adalah pemanfaatan table saw 8? agar bisa memotong secara presisi mengingat limbah tersebut berupa potongan kayu berdimensi kecil. Poin penting lain adalah pada proses penyatuan setiap potongan kayu dengan proses perekatan (adhesion) menggunakan lem kayu berjenis polyurethane dan pada saat bersamaan dilakukan proses penjepitan (clamping) sambungan kayu tersebut menggunakan alat bantu bar clamp agar proses pengeleman menjadi sempurna.Kata kunci: kayu laminasi, limbah kayu jati, table saw, perekatan, clampingAbstractThere are several types of wood waste from the production process such as wood dust, wood shavings, wood chips, and wood scrap waste. Various attempts were made to add value for each type of wood waste including the manufacture of laminated wood, particle wood, MDF, HDF, wood briquettes, wood ornaments, and others. This program utilizes teak wood waste into laminated wooden board products and cooperate with home-based furniture industry group in Mangunsari Village on Semarang Regency. The industrial group has various types of wood waste with a relatively abundant quantity but there is no treatment at all related to the waste other than just being used for cooking and discharged into the environment. Education and training are carried out through this program to help partners in making teak wood waste into laminated wooden boards by utilizing work tools such as table saw, hand planner, hand sander, wood glue, and bar clamp. An important point in the manufacture of laminated wooden boards is the use of a table saw 8 "in order to cut precisely because the waste is in small pieces dimension of wood. Another important point is the process of assy each piece of wood with the adhesion process using polyurethane type of wood glue and at the same time the process of clamping the wood connection using a bar clamp tool so that the gluing process becomes perfectly.Keywords: laminated wood, teak wood waste, table saw, adhesion, clamping

Abstract

Intisari— Biaya distribusi produk yang masih cukup tinggi dan juga lokasi konsumen yang tersebar di berbagai wilayah Pulau Jawa menjadi sebuah tantangan yang cukup kompleks bagi UKM Mina Indo Sejahtera, agar dapat selalu memenuhi mayoritas bahkan seluruh demand dari konsumen potensialnya dengan biaya yang seefisien mungkin. Oleh karena itu, diperlukan sebuah desain jaringan supply chain yang optimal bagi UKM Mina Indo Sejahtera, agar seluruh konsumen dapat tetap terlayani dengan total biaya distribusi yang tetap efisien. Metode yang digunakan yaitu dengan menggunakan formulasi model matematis haversin dan juga Center of Gravity (COG) Adjusting. Koordinat lokasi yang dihasilkan terbukti mampu meminimalkan total jarak tempuh dan juga total biaya yang harus dikeluarkan UKM Mina Indo Sejahtera untuk mendistribusikan produknya ke seluruh market khususnya di Pulau Jawa. Hasil penurunan total jarak tempuh dan total biaya distribusi bulanan yang didapatkan melalui formula haversin dan metode COG Adjusting yaitu sebesar 22% dan 24%. Sehingga, apabila UKM Mina Indo Sejahtera memusatkan distribusinya pada lokasi baru tersebut, total jarak yang ditempuh ke seluruh pasar di Pulau Jawa dapat diminimalkan menjadi sejauh 1.720, 4 kilometer, dengan total biaya distribusi bulanan yang dikeluarkan hanya sebesar Rp Rp 11.736.455,-.. Abstract— The cost of product distribution is still quite high and also the location of consumers spread across various regions of Java Island is a fairly complex challenge for Mina Indo Sejahtera SMEs, in order to always meet the majority and even all demands from potential consumers at the most efficient cost possible. Therefore, an optimal supply chain network design is needed for Mina Indo Sejahtera SMEs, so that all consumers can still be served with efficient total distribution costs. The method used is by using a haversin mathematical model formulation and also Center of Gravity (COG) Adjusting. The resulting location coordinates are proven to be able to minimize the total distance traveled and also the total costs that must be incurred by Mina Indo Sejahtera SMEs to distribute their products to all markets, especially in Java. The results of the reduction in total mileage and total monthly distribution costs obtained through the haversin formula and the COG Adjusting method are 22% and 24%, respectively. Thus, if Mina Indo Sejahtera SMEs concentrated their distribution in the new location, the total distance traveled to all markets on Java Island could be minimized to 1,720, 4 kilometers, with a total monthly distribution cost of only Rp. 11,736,455,-.

Abstract

This community service activity aimed to empower Repro Micro, Small, and Medium Enterprises (MSMEs) in Semarang City to process organic waste, specifically, milk protein waste from the bread industry and banana tree waste from agriculture, into poultry feed pellet products. These products are intended to support livestock food security, environmental management, and social empowerment. The problem-solving method was implemented through an applied green economy approach, engineering a series of poultry feed pellet production machines integrated with an Artificial Intelligence (AI) system. The realization of this engineered technology series adheres to several technical standards and is designed with multi-feature mechanisms: coarse chopping, fine chopping, pulverizing, and pellet molding. The integration of the AI system serves as a virtual assistant to guide the partner in optimally composing the raw material mixture and simultaneously predict the resulting content based on quality parameters. This integration aims to enhance process effectiveness through improved quality outcomes while maintaining production efficiency. The results of the program realization show that the partner is able to utilize the technology effectively to independently produce poultry feed pellets at a cost of approximately IDR 5,850 per kg. Furthermore, the program's impact has demonstrated an ability to enhance self-reliance, competitiveness, environmental awareness, and business sustainability, thereby contributing to community welfare and advancing the people's economy at the MSME level.
