Laminated beams are formed from two or more materials that have different properties. Bamboo laminate is one solution to develop a material to have a better structure. The purpose of this study was to determine the effect of the direction of the bamboo laminate on the flexural strength and compressive strength of the bamboo laminated. The method used is an experimental test by testing the flexural and compressive strength. The beam test refers to SNI 03-3958-1995 and SNI 03-3959-1995. The laminated beam to be tested has a moisture content value below 13% in accordance with the test provisions and has specific gravity between 0.58-0.69 g/cm 3 . Laminated beams with a cross direction variation of (cid:19)(cid:219)(cid:18)(cid:28)(cid:19)(cid:219) have flexural strength of 74.44 MPa and compressive strength of 53.36 MPa. Laminate with a cross direction variation of + (cid:23)(cid:24)(cid:219)(cid:18) - (cid:23)(cid:24)(cid:219) has flexural strength value of 55.34 MPa and compressive strength of 65.57 MPa. The variation of the cross direction (cid:19)(cid:219)(cid:18)(cid:28)(cid:19)(cid:219) directional arrangement has better flexural strength than the (cid:14)(cid:23)(cid:24)(cid:219)(cid:18) - (cid:23)(cid:24)(cid:219) variation, while for the compression test, the (cid:14)(cid:23)(cid:24)(cid:219)(cid:18) - (cid:23)(cid:24)(cid:219) directional arrangement variation has greater test results. The results of the compressive and flexural tests for both variations belong to different Indonesian Classification Bureau (BKI) strength classes, which cross-variation (cid:19)(cid:219)(cid:18)(cid:28)(cid:19)(cid:219) is classified in strength class II for flexural testing and strength class II for compressive testing, while cross variation (cid:14)(cid:23)(cid:24)(cid:219)(cid:18) - (cid:23)(cid:24)(cid:219) is classified in strength class III for flexural testing and strength class I for compressive testing.

Suatu material menjadi tekstil cerdas terhadap perubahan pencangkokan polimer termoresponsif seperti N-isopropilakrilamida (NIPAM). Penelitian ini bertujuan untuk mempelajari proses polimerisasi cangkok NIPAM pada nirtenun lyocell dengan bantuan iradiasi plasma. Dalam kegiatan penelitian ini, telah dilakukan upaya untuk mempolimerisasikan NIPAM menjadi p(n-isopropilakrilamida) atau PNIPAM sekaligus mencangkokkannya pada nirtenun lyocell dengan bantuan iradiasi plasma dari mesin plasma jenis lucutan korona bertekanan atmosfir. Metode penelitian meliputi iradiasi plasma pada permukaan nirtenun lyocell untuk menciptakan radikal bebas permukaan, perendaman NIPAM, pencucian, dan pengeringan nirtenun lyocell hasil proses. Pengujian nilai persentase kadar pencangkokan dan analisis morfologi serat dari nirtenun hasil proses dilakukan untuk mengetahui keberhasilan pencangkokan. Selain itu, keberhasilan polimerisasi NIPAM pada permukaan nirtenun lyocell juga dikonfirmasi melalui analisis gugus fungsi menggunakan spektrometer ATR-FTIR. Dari penelitian yang dilakukan, waktu perendaman dan metode pencucian berpengaruh terhadap kadar pencangkokan dari sampel yang dihasilkan. Diketahui bahwa nilai kadar pencangkokan paling tinggi sebesar 26,11%, yakni pada sampel nirtenun lyocell dengan perendaman NIPAM selama 24 jam tanpa pencucian. Citra SEM juga menunjukkan adanya NIPAM yang terdeposisi pada permukaan nirtenun lyocell. Sementara itu, hasil analisis gugus fungsi pada permukaan nirtenun lyocell hasil penelitian menunjukkan adanya gugus khas dari NIPAM, tetapi tidak dengan gugus khas dari PNIPAM. Hasil studi mengindikasikan bahwa proses pencangkokan telah berhasil, namun polimerisasi belum berhasil dilakukan. ABSTRACT A textile material can be modified into a smart textile against temperature changes through a grafting of thermoresponsive polymer such as N-isopropylacrylamide (NIPAM). This research aims to study plasma radiation-assisted graft polymerization NIPAM to lyocell nonwoven. In this research, efforts have been made to polymerize NIPAM into PNIPAM as well as graft it onto lyocell nonwoven with the assistance of plasma irradiation from an atmospheric corona discharge plasma machine. The research method consists of plasma irradiation on the surface of lyocell nonwoven to create surface free radicals, NIPAM immersion, washing, and drying of the treated lyocell nonwoven. Testing of grafting yield and analysis of fiber morphology from the treated nonwoven were carried out to determine the success of grafting. In addition, the success of NIPAM polymerization on the surface of lyocell nonwoven was confirmed through the functional group analysis using an ATR-FTIR spectrometer. From the research conducted, the immersion time and washing method affected the grafting yield of the resulting samples. It was found that the highest grafting yield was 26.11%, which was in lyocell nonwoven samples with NIPAM immersion for 24 hours without washing. SEM images also showe

bakteri dapat dipandang perlu untuk menambahkan zat antibakteri pada kain kapas. Pada penelitian ini, zat antibakteri yang diaplikasikan pada kain kapas adalah ekstrak jintan hitam. Langkah awal yang dilakukan adalah menentukan konsentrasi optimum ekstrak jintan hitam dengan variasi 10%, 20%, 30%, 40%, dan 50% untuk diaplikasikan pada kain kapas menggunakan cara rendam peras-pemanasawetan ( pad-dry-cure ). Setelah diperoleh konsentrasi optimum, ekstrak diaplikasikan pada kain kapas dengan beberapa variasi metode, yaitu (1) tanpa plasma lucutan korona dan asam sitrat, ABSTRACT One of the clothing materials that are widely used by community is cotton fabric, which is famous for its comfort. Unfortunately, cotton fabric is very susceptible to bacterial colonization which can cause skin problems. Therefore, it is deemed necessary to add an antibacterial agent to cotton fabric. In this study, the antibacterial agent applied to cotton fabric was black cumin extract. The first step was to determine the optimum concentration of black cumin extract with variations of 10%, 20%, 30%, 40%, and 50%, to be applied to cotton fabric using a pad-dry-cure method. After obtaining the optimum concentration, the extract was applied to cotton fabric with several variations of methods, namely (1) without corona discharge plasma and citric acid, (2) with corona discharge plasma only, (3) with citric acid only, and (4) with corona discharge plasma and citric acid. The antibacterial ability test of black cumin extract cotton fabric was carried out using the AATCC TM100-2019 method. The results showed that black cumin extract had the ability as an antibacterial agent on cotton fabric. Cotton fabric with extracts of 30%, 40%, and 50% resulted in the highest reduction percentage, which were respectively 96.6%; 97.0%; and 97.0%; against S. aureus; and 79.4%; 79.5%; and 79.5% against E. coli. The method that produced the highest reduction percentage was the combination of corona discharge plasma technology and citric acid, which resulted in an increase in the reduction percentage to 99.9% of S. aureus and E. coli at an extract concentration of 30%. This method also produces the highest durability against household washing. After 9 times of household washing, the percentage of reduction only decreased from 99.9±0.14% to 77.7±0.3% against S. aureus and 99,9±0.12% decreased to 75.1±0.4% against E. coli.
烘焙食品中的抗烘焙剂可在蛋糕上使用。在笔者看来，在烘焙过程中使用的抗烘焙剂是一种抗氧化剂。目前，最佳抗菌剂浓度分别为 10%、20%、30%、40% 和 50%，可用于干式固化（pad-dry-cure）。通过使用不同的方法，如（1）使用等离子体（Plasma lucutan korona dan asam sitrat）、（2）使用等离子体（Plasma lucutan korona dan asam sitrat）、（3）使用等离子体（Plasma lucutan korona dan asam sitrat）、（4）使用等离子体（Plasma lucutan korona dan asam sitrat）、（5）使用等离子体（Plasma lucutan korona dan asam sitrat）、（6）使用等离子体（Plasma lucutan korona dan asam sitrat）。遗憾的是，棉织物非常容易受到细菌的侵袭，从而引发皮肤问题。因此，有必要在棉织物中添加抗菌剂。在这项研究中，应用于棉织物的抗菌剂是黑小茴香提取物。第一步是确定黑孜然提取物的最佳浓度，浓度分别为 10%、20%、30%、40% 和 50%，使用垫干固化法将其涂在棉织物上。在获得最佳浓度后，用几种不同的方法将提取物涂抹在棉织物上，即（1）不使用电晕放电等离子体和柠檬酸；（2）仅使用电晕放电等离子体；（3）仅使用柠檬酸；以及（4）使用电晕放电等离子体和柠檬酸。采用 AATCC TM100-2019 方法对黑小茴香提取物棉织物进行了抗菌能力测试。结果表明，黑小茴香提取物对棉织物具有抗菌能力。萃取率分别为 30%、40% 和 50%的棉织物对金黄色葡萄球菌的抑菌率最高，分别为 96.6%、97.0% 和 97.0%；对大肠杆菌的抑菌率分别为 79.4%、79.5% 和 79.5%。减少金黄色葡萄球菌和大肠杆菌比例最高的方法是电晕放电等离子技术与柠檬酸的结合，在提取物浓度为 30% 的情况下，减少金黄色葡萄球菌和大肠杆菌的比例提高到 99.9%。这种方法在家庭洗涤中的耐久性也是最高的。经过 9 次家庭洗涤后，对金黄色葡萄球菌的杀灭率仅从 99.9±0.14% 降至 77.7±0.3%，对大肠杆菌的杀灭率从 99.9±0.12% 降至 75.1±0.4%。

Essential oils as the antibacterial substance in textiles are commonly demanded since they are easily found and have additional properties as relaxation therapy. This study aims to receive an antibacterial cloth using eucalyptus oil as a finishing substance gained from the leaves of Melaleuca leucadendra L. from a local industry (Perhutani Gundih, Central Java). The four types of cotton/polyester fabrics were prepared for finishing treatment with the bathing direct application method. They were 100% cotton, 100% polyester, 80%/20% polyester/cotton, and 65%/35% polyester/cotton. FTIR findings proved the existence of the eucalyptus main compound (α-pinene) in those four fabrics. Moreover, the antibacterial tests using S. aureus cultivation showed that only 100% polyester-treated fabric did not obtain antibacterial properties because the diameter of bacterial inhibition was zero millimeters. The other three fabrics potentially have antibacterial properties even if they did not gain a high diameter inhibitor zone.

As a reinforcement, cellulose natural fiber material is used from the pseudostem of the banana plant using the solution casting method using variations of glycerol as a plasticizer (10%, 20%, 30%, 40%, and 50%) and using various compositions of fiber and film in a ratio (30:70, 40:60, and 50:50). The characterizations carried out on its mechanical properties and hydrophilicity. The test results showed that cassava bagasse can be used as a film with an optimum concentration of glycerol of 40% with a tensile strength value of 0.71 MPa and elongation of 101.04%, and the ability to absorb water of 144.68%. The test results on the biocomposite showed that the addition of banana pseudo-stem fiber to starch with an optimum ratio of fiber and film of 50:50 could increase the tensile strength and absorption with a tensile strength value of 0.71 MPa to 4.62 MPa and absorption from 144.68 to 243.21%.

Kenyamanan taktil merupakan salah satu aspek yang menentukan kenyamanan pada pakaian secara keseluruhan. Dalam studi ini, performa kenyamanan taktil pada tiga variasi kain rajut single jersey yang mengandung serat biduri, yaitu: thermolite -biduri (TB) 50%:50%, micropolyester -biduri (MB) 50%:50%, dan excel biduri (EB) 50%:50%, dibandingkan terhadap kain kapas (K) 100% dan poliester (PES) 100%. Kelima jenis kain tersebut juga divariasikan menjadi dua jenis kerapatan jeratan, yaitu rendah dan tinggi. Karakteristik kenyamanan taktil dievaluasi dengan menggunakan alat uji fabric touch tester (FTT). Hasil uji menunjukkan bahwa berdasarkan kriteria nilai primary sensory index (PSI), kain rajut dengan konstruksi kerapatan tinggi dapat menghasilkan nilai smoothness (kehalusan permukaan) , softness (kelembutan) , dan kenyamanan taktil total yang lebih baik dibanding kerapatan ABSTRACT Tactile comfort is one aspect that determines the overall comfort of the clothing. The work focused on studying performance relevant to the tactile comfort of single jersey knitted fabric. The fabrics were made using three fiber blending variation, include: thermolite-biduri (TB) 50%:50%, micropolyester-biduri (MB) 50%:50%, and excel-biduri (EB) 50%:50%. The 100% cotton (K) and 100% polyester (PES) fabrics were made as the comparator. All fabrics were also varied into low and high-density. Tactile comfort characteristics were evaluated using a fabric touch tester (FTT). The test results show that based on the criteria for the value of the primary sensory index (PSI), knitted fabrics with high-density construction can produce better smoothness, softness, and total tactile comfort values than low density. MB knitted fabric with a mixed composition of 50% biduri fiber and 50% polyester microfiber has the potential to produce better tactile comfort and softness characteristics than other fabrics, including 100% cotton and polyester. All high-density biduri knitted fabrics had higher warmness values than cotton and 100% polyester as comparator. TB knitted fabric with a mixed composition of 50% biduri fiber and 50% thermolite has the best warmness value compared to other fabrics.
单面针织布的性能是提高纺织品质量的关键因素。在这项研究中，单面针织衫的各种面料（如：热塑性聚酯纤维（TB）50%:50%、微聚酯纤维（MB）50%:50%、聚酯纤维（EB）50%:50%）的面料性能，与100%聚酯纤维（K）和100%聚醚砜（PES）的面料性能相匹配。这两项指标的比例分别为 100%（K）和 100%（PES）。通过布料触感测试仪（FTT）可对织物进行测试。通过对织物触感测试仪（FTT）进行评估，可以得出织物的平滑度（kehalusan permukaan）、柔软度（kelembutan）和总的触感舒适度（kenyamanan taktil total yang lebih baik dibanding kerapatan ABSTRACT 触觉舒适度是决定衣物整体舒适度的一个方面。这项工作的重点是研究单面针织物的触感舒适性能。织物由三种纤维混纺而成，包括：热涤纶-涤纶（TB）50%:50%、微涤纶-涤纶（MB）50%:50% 和涤纶-涤纶（EB）50%:50%。100%棉（K）和 100%涤纶（PES）织物作为对比。所有织物还分为低密度和高密度两种。使用织物触感测试仪（FTT）对触感舒适性进行了评估。测试结果表明，根据初级感官指数（PSI）值的标准，高密度结构的针织织物比低密度织物能产生更好的平滑度、柔软度和总体触感舒适度值。与其他织物（包括 100%棉和聚酯纤维）相比，混合 50%biduri 纤维和 50%聚酯超细纤维的 MB 针织织物有可能产生更好的触感舒适度和柔软度特性。所有高密度 biduri 针织物的保暖值都高于棉和 100%涤纶织物。与其他面料相比，由 50%比杜里纤维和 50%热石混合制成的 TB 针织面料具有最佳的保暖值。
