Abstract

Biodiesel production from calophyllum inophyllum be obtained via esterification and transesterification, using two continuous reactors with catalyst NaOH at a concentration (0.4 ;0.6,0.8; 1) wt%, calophyllum inophyllum seed oil and reaction temperature (40, 50,60)oC. This research was to determine the effect of catalyst amount and reaction temperature on transesterification of calophyllum inophyllum seed toward yield Fatty Acid Methyl Ester . The last step is analysis yield of Fatty Acid Methyl Ester with Gas Chromatography (GC). The highest yield is obtained on the amount of 1% NaOH catalyst and at a temperature of 60oC with yield of 87.036%.

Abstract

Utilization of rice husks in Indonesia in general is still very limited. Utilization of silica contained in rice husk ash, which has been used, among others, in the manufacture of sodium silicate. Silica compounds themselves can be used in and manufacturing basic materials for electronic and ceramic equipment, glass, rubber, cosmetic products, and pharmaceuticals. The addition of Mg can increase the silica content (SiO2) in rice husk ash. The best results show an effective Mg ratio of Mg addition to increase silica content is 1: 1. produces the highest amount of silica which is 58.12% of the rice husk ash with a size of 140 mesh

Abstract

In an increasingly advanced era, allproperty or home furniture is required to have arenewable innovation and efficiency. This is becauseproperty or home furniture currently has a very largemass or size. Large furniture sizes such as chairs andtables have an average area of 500cm2. Almost 90% ofIndonesian people have tables and chairs as the contentsof their household furniture. Not only functioned athome, in restaurants, cafes, malls, offices, in parks andall places where if there is interaction between humans,there must be chairs and tables as places for interaction.But sometimes the owners of chairs and tables oftencomplain about the size of the tables and chairs, so they need a large enough area to place these two items. Theproblem that exists in society today is the narrowing ofempty land in one place. Sometimes there is homefurniture that is not ergonomic, such as a chair that istoo high, a table that is too low and so on. By using thisanthopometric method, the measurements obtainedinclude a chair along the 95th percentile 25 cm, chairlength 33 cm 95th percentile, table length 68 cm 5thpercentile, chair height 39 cm 5th percentile, table height69 cm 5th percentile, and finally lower surface height. atable of 54 cm on the 95th percentile, and it is hoped thatthe manufacture of a chair flexibility table productdesign can overcome all the problems of land limitationsthat exist in today's society.

Abstract

Mesin parut kelapa adalah salah satu produk mesin dari hasil teknologi yang berfungsi sebagai alat untuk menghancurkan daging buah kelapa menjadi butiran-butiran kecil dengan tujuan untuk memperoleh santan [CH3(CH2)6COOH] yang terkandung di daging buah kelapa. Mesin parut kelapa yang sekarang adalah satu rangkaian dengan mesin selep bumbum yang menggunakan motor bensin sebagai penggerak utamanya, dan mempunyai tiga pulley disetiap poros giliannya sedangkan di mesin motor mempunyai satu pulley, sehingga ketidak efisiensi melepas-pasang v-blet. mesin parut kelapa motor bensin dan mesin parut motor bensin peningkatan efesiensi waktu parut buah kelapa secara signifikan, dengan rata-rata berat buah kelapa 1 kg apabila menggunakan mesin parut motor bensin dapat ditempuh dengan waktu 6.9 menit/kg sedangkan mengunakan mesin parut kelapa motor listrik dapat ditempuh dengan waktu 3.6 menit/kg sehingga didapatkan selisih waktu pelubangan sebesar 3.3 menit/kg.dan perbandingan hasil parutan kelapa yang tercecer antara motor bensin dengan motor listrik didapatkan selilih berat 18,46gram. Kata Kunci : redesain mesin parut, motor listrik, efesiensi.

Abstract

Eksploitasi tanaman liar yang bernilai ekonomi seperti Alocasia jacklyn sp dari hutan secara terus-menerus tanpa diikuti usaha konservasi dan budidaya akan menyebabkan kepunahan. Metode perbanyakan dengan teknik kultur jaringan pada A. jacklyn sampai saat ini belum dilaporkan. Penelitian ini bertujuan mengetahui metode mikropropagasi A. jacklyn melalui optimasi jenis dan konsentrasi zat pengatur tumbuh (hormon) penginduksi tunas dan akar. Pada tahap pertama dilakukan multiplikasi tunas dengan perlakuan variasi konsentrasi benziladenin (BA), yaitu 0; 2; 5; 10 mg.L-1. Pada tahap kedua dilakukan induksi akar pada tunas yang telah diperoleh dengan perlakuan variasi konsentrasi Indole 3 Butirit Acid (IBA), yaitu 0; 1; 2; 3; 4 mg.L-1. Kultur induksi tunas dikultivasi selama 4 minggu dan pada kultur induksi akar selama 6 minggu. Kedua kultur menggunakan medium Murashige dan Skoog tersuplementasi sukrosa 3% (w/v). Hasil observasi pada akhir kultur menunjukkan bahwa perlakuan BA dan IBA secara terpisah berdampak positif pada multiplikasi tunas dan pertumbuhan akar. Aplikasi BA dan IBA secara terpisah tidak berpengaruh signifikan pada pertumbuhan tunas dan jumlah akar. Jumlah dan tinggi tunas optimal pada penelitian ini dicapai pada 2 mg.L-1 BA, selanjutnya panjang akar optimal dicapai pada 2 mg.L-1 IBA.

Abstract

In this study we compared the synthesis of nickel hydroxide nanoparticles using two different solutions, namely tween 20 and PEG (Polyethylene Glycol) 400, the electrolysis method used 0.3 M sodium citrate with the addition of tween 20 and PEG 400, using a potential of 25 Volts for 30 minutes. Obtained nickel hydroxide nanoparticles. Scanning electron microscopy (SEM) is used for morphological characterization of the product. Nickel hydroxide nanoparticles added with tween 20 were in the form of nanoflowers, while nickel hydroxide nanoparticles added with PEG 400 were in a spherical shape.

Abstract

Biobriquette can be used as an alternative fuel because it is made from inexpensive materials and uses simple technology, and it is expected to help overcome the energy (fossil) crisis. The problem is determining how to boost the calorific value of briquettes made from waste biomass materials. Cabbage contains approximately 18.80% fiber, so there is cellulose content that can be processed into high-value products such as briquettes, and using rice husks as fuel can increase the calorific value. The goal of this study is to determine the best calorific value of biobriquettes by varying the method of adding coconut oil and the composition of rice husks and cabbage. The stages of making cabbage and rice husk biobriquettes are raw material preparation, carbonization, adhesive manufacture, briquetting, and quality testing. The variables used are variations in the composition of rice husks: cabbage in ratios of 40:60, 50:50, 60:40, 70:30, and 80:20, as well as the variable method of giving palm oil by mixing with ingredients and dyeing after it becomes briquettes. According to the findings of this study, the best biobriquette mixing ratio resulted in the highest calorific value found in a mixture of 40% rice husk and 60% cabbage with the method of adding palm oil by dipping, with a calorific value of 6.283 kcal/g, a combustion rate of 0.0616 g/minute, and the duration of the flame is 60.26 minutes.

Abstract

In making ceramics, several materials are needed, namely feldspar, silica, clay, and talc and go through several processes that are milling, casting, drying, dry body inspection, glazing and calcination. In order to get good rheology results, we must get quality ingredients. In the Lapindo mudflow, it is often likened to just a natural disaster and very few think about how to manage the mud. Lapindo mud there is a large amount of silica which might be used for making ceramics. To get pure silica in Lapindo mud it is necessary to carry out an extraction process.

Abstract

PT. XYZ is an industry in East Java that produces products made from animal skins as raw materials. The product produced by this industry is loafers. So far, this industry has had problems with leather raw materials which often experience excess supply requiring high investment, although at certain times they also experience shortages which result in not fulfilling consumer demand. MRP is a system specifically designed to ensure the availability of materials, items or components when needed to meet production schedules and ensure the availability of finished products for consumers in situations of surging demand. MRP can answer exactly what material, how much, and when (what, how much and when) is needed so that the production process can run according to schedule. The results of this study indicate that the Material Requirement Planning (MRP) method has a total raw material inventory control cost of Rp. 189,646,600 and by using the company's method, the raw material control value is Rp. 323,325,500 Savings in raw material control costs that can be obtained by applying the MRP method are Rp. 17,416,700 or about 0.94%.
