Abstract

Kampung Batik Kamboja is a tourist village consisting of a community of people fostered by the Pontianak City government to produce various textile crafts. Previously, the production activities carried out were limited to batik products and still used synthetic materials and dyes; this is what underlies the need for assistance related to eco-friendly product innovation. This collaborative assistance has been carried out since 2020. It aims to solve production problems experienced by craftsmen and develop the diversification of products made from natural raw materials to become the hallmark of Kampung Batik Kamboja. Training and assistance that have been carried out include making natural dyes, coloring with shibori, and making textile motifs using eco-print pounding and leaf printing techniques. This assistance succeeded in increasing knowledge and encouraging the community to innovate to produce various environmentally friendly textile products so that they have the potential to increase the community's economy through community-based creative industries.

Abstract

The study aimed to analyze the quality of particle boards from bark fiber of sago (Metroxylon spp) with citric acid as natural adhesives based on physical properties, mechanical properties, and durability from subterranean termites Coptotermes curvignathus Holmgren. Particle boards are made with a size of 30 cm x 30 cm x 1 cm. The experimental factors used in the study included densities (0.7 gr/cm3 and 0.8 gr/cm3) and concentrations of citric acid adhesives (20% and 30%). The material then flow into hotpress with 1800C for 15 minutes and pressure at 25 kg/cm2. Testing of the physical and mechanical properties of particle boards refers to the JIS A 5908-2003 standard and durability against subterranean termites Coptotermes curvignathus Holmgren was conducted based on SNI 01. 7207-2006. The results showed that the densities factor had a significant effect on density, thickness swelling, MOE, MOR, internal bond, screw holding strength, and weight loss of the particle board against termites. Meanwhile concentration of citric acid adhesive significantly affected the density, moisture content, water absorption, thickness swelling, MOR, internal bond, and screw holding strength. The interaction between the densities factor and concentration of citric acid has a significant effect on thickness swelling and density. The physical and mechanical properties of particle boards which fulfill the JIS A 5908 2003 standard were density, moisture content, MOR, and screw holding strength. The durability of particleboard againts termites has a very strong level. The average values of termites mortality were 94% ~ 100%. The average of wood weight loss values were 9.61%~ 18.51%. The particle board made with a density 0.8 gr/cm3 and concentration of citric acid adhesive 30% achieved the highest values on physical properties, mechanical properties and durability to the termites Coptotermes curvignathus.

Abstract

The rendement value of plywood industry is a benchmark of increasing efficiency in utilizing raw materials. Raw materials from natural forests produced into plywood have a yield that is not in accordance with P.15/PHPL-PPHH/2015. The detailed and sequential DMAIC method can analyze the impact of the use of natural forest raw materials. The purpose of the research is to elaborate the application of six sigma (DMAIC) in PT. XYZ and prove the use of six sigma method can increase the yield of plywood production in PT. XYZ to conform to P.15/PHPL-PPHH/2015. The research was conducted in September-November 2020. This research uses six sigma method with DMAIC (Define, Measure, Analyze, Improve and Control) stages in each plywood production process. The results showed that the rendemen increased by 2.14% by applying the six sigma (DMAIC) method. These results were found based on the collection of define and measure data (analysis of waste problems and rendemen of each production process and interviews), processing of analyze and improve data (analysis of causes and proposed problems of low rendemen value) and implementation of data control (analysis on three production processes of low rendemen causes). The proposed improvement is minimalism tearing of finir core at rotary process, so that there is an increase in plywood production rendemen from 88.23% to 90.37%.Keywords : six sigma (DMAIC), rendement, process, plywoodAbstrakNilai rendemen industri kayu lapis merupakan tolak ukur tentang peningkatan efisiensi dalam memanfaatkan bahan baku. Bahan baku dari hutan alam diproduksi menjadi kayu lapis memiliki rendemen yang tidak sesuai dengan P.15/PHPL-PPHH/2015. Penerapan metode DMAIC yang detail dan berurutan dapat menganalisa dampak dari penggunaan bahan baku hutan alam. Tujuan penelitian adalah menguraikan penerapan six sigma model DMAIC di PT. XYZ dan membuktikan penggunaan metode six sigma dapat meningkatkan rendemen produksi kayu lapis di PT. XYZ agar sesuai dengan P.15/PHPL-PPHH/2015(P_15_2015 Efisiensi Bahan Baku_zgZVDf, n.d.). Penelitian dilaksanakan pada September-November 2020. Penelitian ini menggunakan metode six sigma dengan tahapan DMAIC (Define, Measure, Analyze, Improve dan Control) pada setiap proses produksi kayu lapis. Hasil penelitian menunjukkan bahwa rendemen meningkat sebesar 2,14% dengan menerapkan metode six sigma (DMAIC). Hasil ini ditemukan berdasarkan pengumpulan data define dan measure (analisis masalah limbah dan rendemen setiap proses produksi serta wawancara), pengolahan data analyze dan improve (analisis penyebab dan usulan masalah nilai rendemen rendah) serta implementasi data control (analisis pada tiga proses produksi penyebab rendemen rendah). Perbaikan yang diusulkan adalah minimalisir penyobekan finir core proses rotary, sehingga terjadi peningkatan rendemen produksi kayu lapis dari 88,23% menjadi 90,37%.Kata kunci : six sigma (DMAIC), rendemen, proses, kayu lapis

Abstract

The objective of this research is to evaluate the effect of the number of composite layers on the quality of the composite board from sago bark waste and plastic waste, and the number of composite layers that produce the best quality on composite board. The composite board is made with size 30 cm x 30 cm x 1 cm. The composition and division of the material was carried out manually with the polypropylene distribution divided into three parts: the front and rear respectively of 15%, and the center 70% of the plastic weight. Target density of composite boards was 0.7 g / cm3. The treatment used is based on the number of layers composing, which is 5 layers, 7 layers, 9 layers, 11 layers and 13 layers. After mixed the sago bark particle and waste of polypropylene, the materials then compressed with hot press at 180oC with pressure about ± 25 kg / cm2 for 10 minutes. The composite boards then tested the quality included physical and mechanical properties. Testing of physical and mechanical properties refers to JIS A 5908-2003 standard. Physical properties consist of density, moisture content, thickness swelling, and water absorption. Mechanical properties consist of modulus of rupture, modulus of elasticity, internal bonding, and modulus of screw holding strength. The study used a completely randomized design experiment consisting of 5 treatments and 3 replications. The results showed the average value of composite density was range between 0.6962 – 0.7896 g/cm3, the moisture content was range between 4.3388 % - 6.8066%, the thickness swelling was range between 8.2605% - 11.9615%, and water absorption was range between 17.2380% - 22.3867%. The average value of modulus of rupture was range between 60,0632 kg/cm2 – 64,4068 kg/cm2, the modulus of elasticity was range between 17935,1813g/cm2 – 32841,8278 kg/cm2, the internal bonding was range between 1,9268 kg/cm2  - 5,4119 kg/cm2, and the modulus of screw holding strength was range between 78,2530 kg/cm2 – 92,9677 kg/cm2. The composite board made from sago stem bark waste and polypropylene waste plastic with 13 layers treatment is the best composite board and fulfilled the JIS A 5908-2003 standard.

Abstract

The objective of this research was to evaluate the characteristic of composite boards made from coir, plastic waste , and urea formaldehyde (UF). The board samples were manufactured at target density of 0,7 gr/cm3. The weight ratio of waste plastic and coir was 50: 50. the UF adhesive added at 0%, 4%, 8%, 12% and 16% of the total weight of the composite board. The result shows that the characteristic of composite boards improve with UF adhesive added, however no signifivant difference was found statistically.
