The injection molding process is a manufacturing process that is often used in the production of plastic products. Using software with predetermined parameters, injection mold simulation of a predetermined product is carried out on the carabiner design. The parameters used are then assessed with quality prediction based on the best simulation results. If there is a product that does not meet the quality prediction value given (i.e. the value is less than optimal), improvements are made by changing the injection mold design or mold design. Three runner layout designs were made in such a way as to assess which of the runner layout designs for the carabiner mold had the highest quality prediction value. Then, from each runner layout design, variations in gate diameter sizes of 2 mm, 4 mm and 6 mm were made. Based on the simulation results that have been carried out, the best runner and gate layout is obtained in Design 1 with a gate diameter of 4 mm, whose quality prediction value reaches 100%. Then, the lowest quality prediction was obtained in Design 1 with a gate diameter of 6 mm.","PeriodicalId":402840,"journal":{"name":"Techno (Jurnal Fakultas Teknik, Universitas Muhammadiyah Purwokerto)","volume":" 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141129377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pada jamur tiram terdapat kandungan asam amino, kandungan tertinggi pada jamur tiram yaitu asam glutamat. Asam glutamat adalah asam amino non esensial. Asam amino memiliki sifat yang mudah rusak dalam kondisi tertentu. Faktor yang memiliki peran penting dalam proses ekstraksi senyawa asam glutamat yaitu suhu dan waktu ektraksi. Pada proses ekstraksi juga membutuhkan pengoptimalan untuk memperoleh senyawa asam glutamat yang optimum dari jamur tiram. Tujuan dari penelitian ini adalah mengetahui pengaruh faktor suhu dan waktu ekstraksi senyawa asam glutamat pada jamur tiram dengan metode ekstraksi perebusan dengan menggunakan metode faktorial design. Penelitian ini menunjukkan bahwa suhu ekstraksi berpengaruh (signifikan) terhadap nilai kadar asam glutamat, sedangkan waktu ekstraksi tidak berpengaruh (tidak siginfikan). Kondisi optimum ekstraksi adalah suhu 90 oC dan waktu ekstraksi 30 menit. Kondisi optimum ini menghasilkan nilai kadar asam glutamat sebesar 2598.88 mg/L ABSTRACT Oyster mushrooms (Pleurotus ostreatus) are a type of wood mushroom that is easy to cultivate. Oyster mushrooms contain amino acids, the highest content in oyster mushrooms is glutamic acid. Glutamic acid is a non-essential amino acid. Amino acids have the property of being easily damaged under certain conditions. Factors that have an important role in the extraction process of glutamic acid compounds are temperature and extraction time. The extraction process also requires optimization to obtain optimum glutamic acid compounds from oyster mushrooms. The aim of this research is to determine the influence of temperature and time factors for the extraction of glutamic acid compounds on oyster mushrooms using the boiling extraction method using factorial design. This research shows that the extraction temperature has an effect (significant) on the value of Glutamic Acid levels, while the extraction time has no effect (not significant). The optimum extraction conditions are a temperature of 90 oC and an extraction time of 30 minutes. This optimum condition produces a glutamic acid level of 2598.88mg/L.","PeriodicalId":402840,"journal":{"name":"Techno (Jurnal Fakultas Teknik, Universitas Muhammadiyah Purwokerto)","volume":" 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141129287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dalam rangka mengurangi potensi pencemaran limbah kulit singkong maka digali potensi yang terkandung di dalamnya. Berdasarkan analisis yang telah dilakukan pada penelitian sebelumnya diketahui bahwa kulit singkong dapat mengandung selulosa hingga 33%. Adanya kondisi tersebut menyebabkan terbukanya peluang kebermanfaatan kulit singkong sebagai sumber selulosa yang dapat dikembangkan lebih lanjut menjadi material biopolymer ramah lingkungan. Tantangan pengembangan material berbasis selulosa dari limbah pertanian adalah adanya struktur lignoselulosa yang menghambat penetrasi reagen kimia. Oleh karenanya perlu dilakukan proses delignifikasi untuk memecah struktur lignoselulosa, sehingga menurunkan kadar lignin. Pada penelitian ini proses delignifikasi dilakukan dengan metode alkali dengan basa NaOH. Optimasi proses dengan melibatkan variabel terikat berupa konsentrasi NaOH (%), rasio solid/liquid(S/L), waktu (menit) dan suhu (°C) dilakukan dengan metode Response Surface Methodology (RSM) model Central Composite Design. Hasil analisis desirability mendapatkan kondisi optimum delignifikasi kulit singkong dengan pelarut basa NaOH, yaitu: konsentrasi NaOH 8.14%, rasio S/L 6.6, suhu reaksi sebesar 90°C dan lama reaksi selama 111 menit.

With the rapid development of the internet, the availability of IPv4 is increasingly limited, to overcome this problem, IPv6 allocation is used on the web server because it has a larger number of addresses and better security. In this study, the web server performance is tested with the test parameters, namely Time Taken for Tests, Request Per Second, Transfer Rate (Kb/s), Time per Request (ms), and Memory Usage. Testing with Apache Bench is done by providing client requests with varying amounts, with the number of requests from 500 to 500000 requests.

Penelitian ini bertujuan untuk meningkatkan pemahaman tentang sifat-sifat aspal mekanik serta mengembangkan metode yang lebih efektif dalam meningkatkan stabilitasnya. Dalam jurnal ini, akan dibahas beberapa aspek penting terkait stabilitas aspal, termasuk pengaruh komposisi aspal, faktor lingkungan, dan metode pengujian yang digunakan untuk menilai stabilitasnya. Metode pengujian juga merupakan komponen penting dalam penilaian stabilitas aspal. Beberapa metode umum yang digunakan termasuk uji Marshall dan uji stabilitas-dengan-batas. Pada penelitian dapat disimpulkan bahwa stabilitas aspal memiliki peran penting dalam memastikan kekuatan dan daya tahan campuran aspal dalam menghadapi beban lalu lintas dan perubahan cuaca. Stabilitas aspal dapat dipengaruhi oleh beberapa faktor, seperti jenis aspal yang digunakan, komposisi aspal dan agregat dalam campuran, serta proses produksi dan pengolahan campuran aspal. Faktor-faktor tersebut diuji melalui pengukuran kepadatan, stabilitas, dan keausan campuran aspal untuk memverifikasi bahwa campuran aspal dapat mengatasi berbagai beban lalu lintas dan kondisi cuaca.
