PERBANDINGAN PAPAN GIPSUM SERAT DAUN NENAS (ANANAS COMOSUS L. MERR) TERHADAP PAPAN GIPSUM KOMERSIL DILIHAT DARI SIFAT FISIS DAN MEKANIS BERDASARKAN SNI SPESIFIKASI PANEL ATAU PAPAN GIPSUM 03-6384-2000
Get PDFThe use of synthetic fiber gipsum board began to be reduced and replaced with fiber derived from nature, one of the fibers that can be replaced is a pineapple fiber. Therefore, further research on the utilization of pineapple fiber waste as a substitute for synthetic fiber is required. This research is a comparative quantitative research using experimental method by conducting 2 (two) characteristic tests consisting of physical properties test and mechanical properties test with pineapple fiber usage of 5% and 6% as gipsum board fiber. Based on physical and mechanical properties test, it was found that pineapple fiber gipsum board with 6% fiber usage had better value and quality compared to commercial gipsum board. This result can be used as reference of testing about building materials that are environmentally friendly and can be applied as one of the material resources in vocational education.

STUDI KUAT TEKAN BAMBU BETUNG DAN BAMBU HITAM AKIBAT SERANGAN RAYAP TANAH
Get PDFThis study aims to determine betung and black bamboo's compressive strength due to termites attacks. The research was conducted at the materials test lab at Universitas Negeri Jakarta and Bogor Agricultural University from 1st October 2016 until 30th January 2017. This research method based on ISO-22157:2004 was using the direct testing of compressive strength in the materials test lab. This research used two kinds of bamboo, betung and black bamboo, which amounts to 40 samples. Each bamboo has 20 samples. By the position, each from the base and middle section has ten samples. While each for the treatment by termites and with no termites has five samples. Based on the research result, it can be concluded that the average of the compressive strength value for the betung bamboo from the base and the middle section that given termites have decreased rather than the bamboo that not given termites 14% to be 6%. In comparison, the black bamboos in the middle section have the same decrease on the average of the compressive strength value with the betung bamboo 9,2% to be 23%. But, black bamboos on the base section have the otherwise where the average of the compressive strength that given termites greater than the bamboo that not given termites 3,6% to be 0%. That matter can be caused by termites' attack absences on the base section of the black bamboo samples. In terms of losing weight, all samples lost the weight 6,8% to be 5,5%. This matter happened because the termites attacked the bamboo. But, the bamboo that termites do not attack also can lose weight and can be caused by other factors such as weather (heat and rain) and fungus

ANALISIS HUBUNGAN EFIKASI DIRI DAN KEMAMPUAN LITERASI DIGITAL DENGAN HASIL BELAJAR SIMULASI DIGITAL
Get PDFThe research objective was to analyze the positive relationship between self-efficacy and digital literacy skills, both together and independently, with digital simulation learning outcomes. The population in this study were all students of SMK Taman Harapan 1 Bekasi in the 2020/2021 academic year. Sampling was done by random sampling as many as 72 students from four expertise programs. The digital simulation learning outcome instrument uses a test while the self-efficacy instrument and digital literacy skills use a non-test in the form of a Likert scale. The research hypothesis was tested using correlation and multiple regression. The results show that: 1) There is a positive relationship between self-efficacy and digital simulation learning outcomes, 2) there is a positive relationship between digital literacy skills and digital simulation learning outcomes, and 3) there is a positive relationship between self-efficacy and digital literacy together with Digital Simulation learning outcomes. The conclusion of this research is that self-efficacy and digital literacy skills are positively related to Digital Simulation learning outcomes, both together and independently. Thus, the higher the self-efficacy and digital literacy skills of the students, the higher the learning outcomes of digital simulation for students of SMK Taman Harapan 1 Bekasi.

ANALISIS PRODUK ROLLADE AYAM TERHADAP DAYA TERIMA KONSUMEN DAN MASA SIMPAN
Get PDFThe research was to analyzed the effect of chicken rolade product with the addition of vegetables to consumer acceptance and shelf life in terms of organoleptic test on color, aroma, taste and texture aspects. Furthermore, the test of the shelf life of the product. Based on the color aspect most liked the addition of carrots with a percentage of 70% with a value of 4.1. Furthermore, the taste aspect most liked the addition of carrots with a percentage of 50% with a value of 4.17. Then the aroma aspect most liked the addition of carrots with the percentage of 50% and 60% with a value of 3.9. And the texture aspect most liked the addition of carrots with a percentage of 60% with a value of 4.17. The result of variance analysis on the length of rolled storage with the addition of carrot shows that the storage time has significant effect (α = 0.05) to the increase of rollade water content. The value of F arithmetic for the source of the old variance of storage is 157.1 and the value of F table 4.76. F count> F table, then reject H0, it means that storage period has an effect on rollade water content with 50%, 60% and 70% carrot addition.

KAPASITAS PELAT LANTAI METODE HALF-SLAB DAN METODE KONVENSIONAL BERDASARKAN VARIASI KETEBALAN
Get PDFInnovation in floor plate methods has been developing nowadays, one of the methods is the precast method. However, this method cannot behave monolithically with other structures so that the deflection does not meet the permit. To overcome this problem then the half-slab plate innovation comes with a combination of precast and conventional method for the topping. This study discusses the ratio of half-slab and conventional floor plate capacity based on the thickness variation. The capacity analysis covers the bending moment, shear force, deflection and stress due to gravity loads. The total thickness of plate was 120 mm and 130 mm, with the three thickness variations which were the precast is thicker than the topping, the topping is thicker than the precast, and the topping is equal to the precast. The results show that the half-slab plate capacity is 8 to 20 times larger than the conventional plate, due to the lifting and shoring forces. In addition, the variations in the topping and precast thickness affect the value of half-slab capacity, which is the thicker the precast the greater the capacity. Adding thickness every 5 mm could increase the moment capacity by 1,58-7,14%, the shear capacity by 1,61-7,14%, the deflection by 1,69-2,08% and could decrease the normal voltage by 1,76%. So the good variation in the half-slab plate thickness is the plate with the precast thickness which is smaller than the topping thickness. From the two types of plates, plates with a thickness of 130 mm have the capacity 4 to 8 times larger than 120 mm. This is influenced by the lift point placement, shoring plots and a larger 130 mm plate width.
