Abstract

AbstrakBalok adalah komponen struktur lentur yang memikul beban gravitasi, beban gravitasi ini berupa beban mati danbeban hidup yang bekerja tegak lurus dengan sumbu longitudinal balok. Salah satu bentuk balok yang efisienadalah balok profil I yang dibentuk dengan pengelasan atau yang dikenal dengan sebutan balok baja I built-up. Dalam penelitian eksperimental ini, balok baja dibuat dengan memotong lembaran pelat baja menjadi elemenelemenpelat sayap dan pelat badan dengan menggunakan pengelasan sehingga membentuk suatu balok bajaprofil I (balok baja I built-up). Sedangkan konstruksi balok yang digunakan adalah konstruksi balok sederhana(simple beam) dengan beban terpusat di tengah bentang. Penelitian ini bertujuan menganalisis kapasitas lenturdan mengetahui perilaku tekuk balok baja I built-up. Hasil dari ekeperimen ini dibandingkan dengan perhitungansesuai SNI 03-1729-2002 dan validasi dengan menggunakan software ANSYS. Dari penelitian ini didapatkan kapasitas lentur beradasarkan eksperimen lebih tinggi dibanding dengan SNI 031729-2002danANSYS.Sedangkankeruntuhanyangterjadiadalahkeruntuhantekuktorsilateral.Katakunci:built-up,momenkapasitas,tekuktorsilateralAbstract Beam is a structural member that carries a dead load or live load that works perpendicular to its longitudinal axisis beam. One form of an efficient beam is a beam profile I which is formed by welding or known as I built-upbeam.In this experimental study, the steel beam is made by cutting the sheet of steel plate into wing plate elements andbody plate by using welding to form a steel profile I (steel beam I built-up). The construction of beam is used asimple beam with concentrated load in the middle of the span. This study aims to obtain bending capacity andknow the buckling behavior of I built-up steel beam. The result of this experiment is compared with thecalculation according to SNI 03-1729-2002 and validation using ANSYS software.From this research, the bending capacity based on experiments is higher than that of SNI 03-1729-2002 andANSYS. While the collapse that occurs is the collapse of lateral torsional buckling.Keywords : built-up, bending capacity, lateral torsional buckling

Abstract

AbstrakBerdasarkan data jumlah tangkap ikan di Pelabuhan Perikanan Nusantara (PPN) Brondong, menunjukkanbahwa rata-rata jumlah tangkap ikan selama 11 tahun terakhir sejumlah 65017 ton pertahun. Pada tahun2016 jumlah tangkap ikan sebesar 66179 ton dan terjadi kenaikan yang sangat signifikan pada tahun 2017sejumlah 130742 ton. Data tersebut jelas sangat mengkhawatirkan, karena terjadi overfishing yang dapatmengakibatkan populasi ikan semakin berkurang. Pada penelitian ini dilakukan prediksi jumlah tangkapikan yang ada di Pelabuhan Perikanan Nusantara (PPN) Brondong guna mengontrol jumlah tangkap ikan,untuk membantu program pemerintah dalam mengelola hasil laut. Pada penelitian ini menggunakanmetode fuzzy time series model Chen, karena data tangkap ikan terkait dengan musim. Hasil prediksimenunjukkan tingkat error sebesar 28%.Kata Kunci: Pelabuhan Perikanan Nusantara Brondong, Prediksi Jumlah Tangkap Ikan, Fuzzy TimeSeries Model ChenAbstractBased on the data of Brondong National Fishing Port, the average number of fish caught for the last 11years is 65017 tons per year.

Ruang dalam kompor dilapisi dengan beton dari cor semen denganketebalan mencapai 5 cm. Kompor ini menggunakan tambahan teknologi blower dari kipas angin untukmembantu proses nyala api, pembakaran dan arah api. Hasilnya kompor biomassa ini mampu digunakanuntuk memasak dodol mencapai 5 jam.Kata Kunci: Kompor Biomassa; Bahan Bakar Kayu, Plat Besi, Blower. Abstract Wood-based biomass stoves had been made to be used by UKM entrepreneurs engaged in the seaweedprocessing into variety of snacks. The stove was made of 2 mm iron plate with dimensions of 30 cm x 30cm x 40 cm so that it can accommodate a lot of fuel and is not easy to run out. The space in the stove wascoated with concrete from a cement which is up to 5 cm thick. This stove used additional blowertechnology from the fan in order to help the flaming process, combustion and the direction of fire. Theresult is that this biomass stove can be used to cook dodol for up to 5 hours.Keywords: Biomass Stove; Wood Fuel, Iron Plate, Blower.

Abstract

Quality improvement activities can help companies maintain and improve the quality of their products bymaking improvements to the level of being broken product to zero damage. PT. Gemilang Inti Sukses is aProfit-oriented Chicken Porong Home Industry engaged in the agribusiness sector, in the process of cuttingchickens there are several obstacles that can affect the level of quality of chicken slaughtered products,Therefore this study aims to determine the quality problems of chicken slaughter and increase the resultsproduct quality at PT. Gemilang Inti Sukses. The method that will be used in this research is the Six Sigmamethod on the DMAIC (Define, Measure, Analyze, Improve, Control) concept. The results showed that ofthe 20 days sample that was 6,540 tails, it was found that the number of slaughtered chickens was 2,230chickens with the details of bruised chicken heads, broken chicken wings, bruised chicken body parts, lessclean feather extraction, and internal taking. not clean enough. While the company's performancemeasurement is at Sigma 3.85 level with a 9.292 DMPO value, which means that in 1 million pieces ofchicken there are 9,292 chickens that are deformed. From the Pareto diagram, it is known that 80% of thedefects are broken chicken wings and bruised chicken parts. Then from the cause and effect diagram it isknown that human resource factors are the main cause of broken chicken wing flaws and bruised chickenbody parts, therefore from the results of this study the company needs to improve quality with morediscipline towards human resource operational standards and conduct supervision and evaluation ofemployee performance.
