description Publicationkeyboard_double_arrow_right Article , Journal 2014Publisher:Lembaga Penelitian dan Pengabdian kepada Masyarakat (LP2M) Authors: Wahyono Hadi; Anindya Prawita Sari;Air sumur merupakan air tanah yang sering kali digunakan masyarakat untuk aktivitas sehari-hari. Air sumur dengan kadar organik dan deterjen tinggi tidak layak dikonsumsi masyarakat karena dapat menyebabkan berbagai macam penyakit. Selain itu, adanya zat organik dan deterjen mempengaruhi warna dan bau air sumur sehingga tidak layak konsumsi. Slow sand filter merupakan unit pengolahan yang mampu meremoval zat organik pada air. Slow sand filter dan rapid sand filter tidak menggunakan bahan kimia dalam proses pengolahan sehingga lebih ekonomis dan efektif. Sedangkan ozon, efektif digunakan untuk meremoval zat organik yang ada dalam air dengan mengubah rantai zat organik menjadi lebih sederhana. Tujuan penelitian ini adalah untuk mengetahui keefektifan penggunaan slow sand filter, ozon generator dan rapid sand filter dalam menyisihkan beban deterjen dan zat organik pada air sumur. Hasil penelitian menunjukkan bahwa efisiensi removal pada unit slow sand filter untuk beban organik dan deterjen sebesar 57,6% dan 60,5 %, pada unit ozonasi sebesar 47,4% dan 17,5%, dan pada unit rapid sand filter sebesar 50,0% dan 50,9 %.

Salah satu permasalahan adalah bagaimana memanfaatkan potensi energi aliran air yang relatif kecil. Maka dari itu guna memanfaatkan dan meningkatkan potensi energi aliran air yang relatif kecil diperlukan penelitian. Pemanfaatan energi air pada penelitian ini adalah pemanfaatan energi kinetik aliran air. Energi mekanik yang merupakan transformasi dari energi kinetik aliran air dimanfaatkan untuk menggerakkan turbin atau kincir. Turbin poros vertikal tipe Savonius ini cocok digunakan untuk memanfaatkan energi aliran air yang relatif kecil. Penelitian dengan judul “Rancang Bangun Turbin Air Sungai Poros Vertikal Tipe Savonius dengan Menggunakan Pemandu Araha Aliran” dilakukan dengan metode eksperimen, dimana hasil dari rancang bangun turbin akan dilakukan pengujian dan pengambilan data. Data pengujian yang diperoleh berdasarkan dari pengaruh variasi kecepatan aliran 0,30 ; 0,57 ; 0,85 dan 1,08 (m/detik) serta pengaruh dari pemandu arah aliran. Performansi diperoleh dari hasil pengujian dan pengukuran. Diperoleh Cp maksimum 0,13 pada TSR 1,53. Kecepatan putar turbin maksimum diperoleh sebesar 162 RPM dan daya keluaran maksimum generator sebesar 2,31 Watt. Penggunaan pemandu arah aliran dapat meningkatkan performansi turbin Savonius diperoleh efisiensi mekanis turbin rata-rata 90,40% dan efisiensi elektris generator rata-rata 90,20%. Sehingga dapat disimpulkan bahwa dengan kecepatan aliran air yang sangat rendah turbin tipe Savonius dapat membangkitkan energi listrik.

Yapay sinir ağ mimarisi olarak ileri beslemeli geri yayılımlı yapay sinir ağı kullanılmıştır. Ölçüm hassaslığından dolayı performans parametreleri modellenmesine rağmen egzoz emisyonları modellenememiştir. Püskürtme avansı için optimizasyonlar hafif (yokuş aşağı); ortalama hız (1600 d/dk), düşük tork (200 Nm) çalışma şartı, normal (düz yol); ortalama hız (1600 d/dk), ortalama tork (1000 Nm) çalışma şartı, ağır (yokuş yukarı); maksimum hız (2200 d/dk), yüksek tork (1800 Nm) çalışma şartı şeklinde koşullar tanımlanarak optimizasyonlar bu şartlara göre en yüksek performans elde edilecek şekilde yapılmıştır. Bu çalışma şartları için optimum avans değerleri (üst ölü nokta 0o'yi ifade etmek üzere) sırası ile -2o, -10o, -14o olarak bulunmuştur.Benzinli motorda alkol (etanol ve metanol) kullanımı için optimizasyonlar maksimum tork, maksimum güç, minimum özgül yakıt tüketimi (BSFC) değerleri için yapılmıştır. Yapılan modelleme ve optimizasyonlar doğrultusunda; performans dikkate alındığında, %11 metanol, %1 etanol içeren benzin karışımı, yakıt tüketimi dikkate alındığında ise %2 metanol içeren benzin karışımının kullanımının daha iyi sonuçlar verdiği tespit edilmiştir. Ayrıca çalışma sonucunda yeterli hassaslığa sahip deney verileri kullanılması durumunda YSA'nın içten yanmalı motorlara başarılı bir şekilde uygulanabileceği kanısına varılmıştır. In this study, the influence of injection timing to performance and exhaust emissions on a diesel engine and the influence of using alcohol to performance on a gasoline engine were investigated with the aid of Artificial Neural Network (ANN). Feed forward back propagation network was used as ANN architecture. Despite of the performance parameters were modelled, the exhaust emissions could not been modelled due to measurement uncertainity. Easy (downhill); medium speed (1600rpm), low torque (200Nm) work condition, normal (straight road); medium speed (1600 rpm), medium torque (1000Nm) work condition and hard (uphill); maximum speed(2200rpm), high torque (1800Nm) work conditions were described and the injection timing was optimized to obtain maximum performance in this conditions. Optimum injection timing values were identified as -2o, -10o, -14o (0o as the top dead center) respectively.For usage of alcohol on spark ignition engines, the rate of alcohols (ethanol and methanol) were optimizated to obtain maximum torque, maximum effective power and minimum brake specific fuel consumption. According to the modelled and optimized results, %11 methanol and %1 ethanol mixed gasoline has more efficient results take into motor performance. Moreover, the minimum fuel consumption has been observed by using %2 methanol mixed gasoline. The results revealed that, the ANN can be successively applied for modelling the internal combustion engine by using experimental data with sufficent precision. 130

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type 2020Publisher:UIN Ar-Raniry Authors: Hemi Faradila;Act Number 4 of 2009 about Mineral and Coal Mining allows latitude in exploiting natural resources. However, the act tends to claim ‘resource used oriented law’. The purpose of this research is to devise whether Act Number 4 of 2009 about Mineral and Coal has accommodated the aspect of environmental’s protection and the principles of environmental’s management following Act Number 32 of 2009 about Environmental’s Protection and Management as known as UUPPLH, especially over licensing of mineral and coal as preventive juridical. This research is based on prescriptive analysis by descriptive and juridical normative approaches. A principle that is implemented in this research is the Principle of State Responsibility and Principle of Sustainable Development and Environmental Concept. The result of this research concludes that Act Number 4 of 2009 about Mineral and Coal Mining has not accommodated optimally yet regarding environmental’s protection over mineral and coal mining business. Based on this fact, mineral and coal mining projects cause pollution and environmental damages sustainably. Whereas, based on a substantial law system, the rule of the law normatively has autonomous force as an idea that determines public interest in economic and environmental aspects. The contribution of this research will be recommended to the development of environmental law and environmental sustainability.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article , Other literature type 2020Publisher:UIN Ar-Raniry Authors: Hemi Faradila;Act Number 4 of 2009 about Mineral and Coal Mining allows latitude in exploiting natural resources. However, the act tends to claim ‘resource used oriented law’. The purpose of this research is to devise whether Act Number 4 of 2009 about Mineral and Coal has accommodated the aspect of environmental’s protection and the principles of environmental’s management following Act Number 32 of 2009 about Environmental’s Protection and Management as known as UUPPLH, especially over licensing of mineral and coal as preventive juridical. This research is based on prescriptive analysis by descriptive and juridical normative approaches. A principle that is implemented in this research is the Principle of State Responsibility and Principle of Sustainable Development and Environmental Concept. The result of this research concludes that Act Number 4 of 2009 about Mineral and Coal Mining has not accommodated optimally yet regarding environmental’s protection over mineral and coal mining business. Based on this fact, mineral and coal mining projects cause pollution and environmental damages sustainably. Whereas, based on a substantial law system, the rule of the law normatively has autonomous force as an idea that determines public interest in economic and environmental aspects. The contribution of this research will be recommended to the development of environmental law and environmental sustainability.

Dalam percobaan ini, ekstraksi reaksi dipakai untuk menghasilkan bodiesel dari mesokarp buah sawit menggunakan dimetil karbonat dan novozym 435 sebagai katalis secara enzimatis. Metanol tidak digunakan sebagai pelarut karena dipercaya dapat menghambat kerja enzim. Variabel yang dipelajari meliputi suhu reaksi sekitar 65 OC waktu reaksi yang dilakukan secara kontinu(4,8,12,16,20,24 jam). Hasil kadar biodiesel yang di dapat sebesar 88,1324%, kadar monodigliserida 0,3132%, kadar digliserida 1,7565%, dan trigliserida2,3212 % membuat biodiesel yang didapat cukup besar. Reactive extraction can be used as a method of making biodiesel with the acquisition of high yield levels , low production costs , the reaction time efficiency and reduce the use of excess reagent , thus producing biodiesel pretty good . In this experiment , the extraction reaction is used to generate bodiesel of mesocarp oil using dimethyl carbonate and 435 novozym as enzymatic catalysts .

Berdasarkan hasil analisis ultimate dan proximate, batubara memiliki nilai kalor 5349 Kkal/kg dan Ubi karet (biomassa) memiliki nilai kalor 3319 Kkal/kg. Bahan ubi karet memiliki nilai kalor rendah dan tidak termasuk ke dalam bahan makanan karena mengandung unsur kimia asam sianida yang bersifat racun. Penelitian ini dilakukan untuk memanfaatkan biomassa menjadi biobriket yang memiliki nilai tambah , dan menjadi energi padat yang ramah lingkungan. Ada dua faktor untuk menentukan kualitas biobriket yaitu pengaruh variasi rasio pencampuran, pengaruh tekanan pengepresan dan ukuran partikel. Pembuatan biobriket meliputi penghancuran, pengeringan, pengecilan ukuran, pengayakan, pencampuran, pencetakan dan pengujian. Biobriket yang dihasilkan berbentuk silinder memiliki diameter 3 cm dengan tekanan pengepresan 7 metrik ton. Analisis biobriket meliputi uji kuat tekan, uji densitas dan relaksasi, uji kadar air, kadar abu, uji zat terbang, uji karbon tetap dan uji nilai kalor. Hasil yang diharapkan dalam penelitian ini ialah memberikan nilai jual yang tinggi pada batubara tingkat rendah dan menjadi salah satu alternatif produk bahan bakar padat dan ramah lingkungan yang dapat digunakan oleh masyarakat untuk keperluan memasak. Berdasarkan hasil pengujian, biobriket terbaik memiliki ukuran partikel 60 mesh. Hasil yang diperoleh menunjukkan bahwa ukuran partikel terbaik berada pada pencampuran batubara dan ubi karet dengan rasio 9 : 1, jumlah nilai kalor tertinggi mencapai 5146 Kkal/kg.Kata kunci: batubara, biobriket, biomassa, uji mekanik, uji sifat fisik

description Publicationkeyboard_double_arrow_right Article , Journal 2014Publisher:Lembaga Penelitian dan Pengabdian kepada Masyarakat (LP2M) Authors: Wahyono Hadi; Anindya Prawita Sari;Air sumur merupakan air tanah yang sering kali digunakan masyarakat untuk aktivitas sehari-hari. Air sumur dengan kadar organik dan deterjen tinggi tidak layak dikonsumsi masyarakat karena dapat menyebabkan berbagai macam penyakit. Selain itu, adanya zat organik dan deterjen mempengaruhi warna dan bau air sumur sehingga tidak layak konsumsi. Slow sand filter merupakan unit pengolahan yang mampu meremoval zat organik pada air. Slow sand filter dan rapid sand filter tidak menggunakan bahan kimia dalam proses pengolahan sehingga lebih ekonomis dan efektif. Sedangkan ozon, efektif digunakan untuk meremoval zat organik yang ada dalam air dengan mengubah rantai zat organik menjadi lebih sederhana. Tujuan penelitian ini adalah untuk mengetahui keefektifan penggunaan slow sand filter, ozon generator dan rapid sand filter dalam menyisihkan beban deterjen dan zat organik pada air sumur. Hasil penelitian menunjukkan bahwa efisiensi removal pada unit slow sand filter untuk beban organik dan deterjen sebesar 57,6% dan 60,5 %, pada unit ozonasi sebesar 47,4% dan 17,5%, dan pada unit rapid sand filter sebesar 50,0% dan 50,9 %.

Sedangkan ozon, efektif digunakan untuk meremoval zat organik yang ada dalam air dengan mengubah rantai zat organik menjadi lebih sederhana. Tujuan penelitian ini adalah untuk mengetahui keefektifan penggunaan slow sand filter, ozon generator dan rapid sand filter dalam menyisihkan beban deterjen dan zat organik pada air sumur. Hasil penelitian menunjukkan bahwa efisiensi removal pada unit slow sand filter untuk beban organik dan deterjen sebesar 57,6% dan 60,5 %, pada unit ozonasi sebesar 47,4% dan 17,5%, dan pada unit rapid sand filter sebesar 50,0% dan 50,9 %.

Salah satu permasalahan adalah bagaimana memanfaatkan potensi energi aliran air yang relatif kecil. Maka dari itu guna memanfaatkan dan meningkatkan potensi energi aliran air yang relatif kecil diperlukan penelitian. Pemanfaatan energi air pada penelitian ini adalah pemanfaatan energi kinetik aliran air. Energi mekanik yang merupakan transformasi dari energi kinetik aliran air dimanfaatkan untuk menggerakkan turbin atau kincir. Turbin poros vertikal tipe Savonius ini cocok digunakan untuk memanfaatkan energi aliran air yang relatif kecil. Penelitian dengan judul “Rancang Bangun Turbin Air Sungai Poros Vertikal Tipe Savonius dengan Menggunakan Pemandu Araha Aliran” dilakukan dengan metode eksperimen, dimana hasil dari rancang bangun turbin akan dilakukan pengujian dan pengambilan data. Data pengujian yang diperoleh berdasarkan dari pengaruh variasi kecepatan aliran 0,30 ; 0,57 ; 0,85 dan 1,08 (m/detik) serta pengaruh dari pemandu arah aliran. Performansi diperoleh dari hasil pengujian dan pengukuran. Diperoleh Cp maksimum 0,13 pada TSR 1,53. Kecepatan putar turbin maksimum diperoleh sebesar 162 RPM dan daya keluaran maksimum generator sebesar 2,31 Watt. Penggunaan pemandu arah aliran dapat meningkatkan performansi turbin Savonius diperoleh efisiensi mekanis turbin rata-rata 90,40% dan efisiensi elektris generator rata-rata 90,20%. Sehingga dapat disimpulkan bahwa dengan kecepatan aliran air yang sangat rendah turbin tipe Savonius dapat membangkitkan energi listrik.

Yapay sinir ağ mimarisi olarak ileri beslemeli geri yayılımlı yapay sinir ağı kullanılmıştır. Ölçüm hassaslığından dolayı performans parametreleri modellenmesine rağmen egzoz emisyonları modellenememiştir. Püskürtme avansı için optimizasyonlar hafif (yokuş aşağı); ortalama hız (1600 d/dk), düşük tork (200 Nm) çalışma şartı, normal (düz yol); ortalama hız (1600 d/dk), ortalama tork (1000 Nm) çalışma şartı, ağır (yokuş yukarı); maksimum hız (2200 d/dk), yüksek tork (1800 Nm) çalışma şartı şeklinde koşullar tanımlanarak optimizasyonlar bu şartlara göre en yüksek performans elde edilecek şekilde yapılmıştır. Bu çalışma şartları için optimum avans değerleri (üst ölü nokta 0o'yi ifade etmek üzere) sırası ile -2o, -10o, -14o olarak bulunmuştur.Benzinli motorda alkol (etanol ve metanol) kullanımı için optimizasyonlar maksimum tork, maksimum güç, minimum özgül yakıt tüketimi (BSFC) değerleri için yapılmıştır. Yapılan modelleme ve optimizasyonlar doğrultusunda; performans dikkate alındığında, %11 metanol, %1 etanol içeren benzin karışımı, yakıt tüketimi dikkate alındığında ise %2 metanol içeren benzin karışımının kullanımının daha iyi sonuçlar verdiği tespit edilmiştir. Ayrıca çalışma sonucunda yeterli hassaslığa sahip deney verileri kullanılması durumunda YSA'nın içten yanmalı motorlara başarılı bir şekilde uygulanabileceği kanısına varılmıştır. In this study, the influence of injection timing to performance and exhaust emissions on a diesel engine and the influence of using alcohol to performance on a gasoline engine were investigated with the aid of Artificial Neural Network (ANN). Feed forward back propagation network was used as ANN architecture. Despite of the performance parameters were modelled, the exhaust emissions could not been modelled due to measurement uncertainity. Easy (downhill); medium speed (1600rpm), low torque (200Nm) work condition, normal (straight road); medium speed (1600 rpm), medium torque (1000Nm) work condition and hard (uphill); maximum speed(2200rpm), high torque (1800Nm) work conditions were described and the injection timing was optimized to obtain maximum performance in this conditions. Optimum injection timing values were identified as -2o, -10o, -14o (0o as the top dead center) respectively.For usage of alcohol on spark ignition engines, the rate of alcohols (ethanol and methanol) were optimizated to obtain maximum torque, maximum effective power and minimum brake specific fuel consumption. According to the modelled and optimized results, %11 methanol and %1 ethanol mixed gasoline has more efficient results take into motor performance. Moreover, the minimum fuel consumption has been observed by using %2 methanol mixed gasoline. The results revealed that, the ANN can be successively applied for modelling the internal combustion engine by using experimental data with sufficent precision. 130

Dalam percobaan ini, ekstraksi reaksi dipakai untuk menghasilkan bodiesel dari mesokarp buah sawit menggunakan dimetil karbonat dan novozym 435 sebagai katalis secara enzimatis. Metanol tidak digunakan sebagai pelarut karena dipercaya dapat menghambat kerja enzim. Variabel yang dipelajari meliputi suhu reaksi sekitar 65 OC waktu reaksi yang dilakukan secara kontinu(4,8,12,16,20,24 jam). Hasil kadar biodiesel yang di dapat sebesar 88,1324%, kadar monodigliserida 0,3132%, kadar digliserida 1,7565%, dan trigliserida2,3212 % membuat biodiesel yang didapat cukup besar. Reactive extraction can be used as a method of making biodiesel with the acquisition of high yield levels , low production costs , the reaction time efficiency and reduce the use of excess reagent , thus producing biodiesel pretty good . In this experiment , the extraction reaction is used to generate bodiesel of mesocarp oil using dimethyl carbonate and 435 novozym as enzymatic catalysts . Methanol is not used as a solvent because it is believed to inhibit the enzyme . The variables studied include a reaction temperature of about 65 OC reaction time is done continuously ( 4,8,12,16,20,24 hours ) . Results biodiesel content in a can of 88.1324 % , 0.3132 % monodigliserida levels , the levels of 1.7565 % diglycerides and triglycerides 2,3212 %make biodiesel obtained quite large .

Berdasarkan hasil analisis ultimate dan proximate, batubara memiliki nilai kalor 5349 Kkal/kg dan Ubi karet (biomassa) memiliki nilai kalor 3319 Kkal/kg. Bahan ubi karet memiliki nilai kalor rendah dan tidak termasuk ke dalam bahan makanan karena mengandung unsur kimia asam sianida yang bersifat racun. Penelitian ini dilakukan untuk memanfaatkan biomassa menjadi biobriket yang memiliki nilai tambah , dan menjadi energi padat yang ramah lingkungan. Ada dua faktor untuk menentukan kualitas biobriket yaitu pengaruh variasi rasio pencampuran, pengaruh tekanan pengepresan dan ukuran partikel. Pembuatan biobriket meliputi penghancuran, pengeringan, pengecilan ukuran, pengayakan, pencampuran, pencetakan dan pengujian. Biobriket yang dihasilkan berbentuk silinder memiliki diameter 3 cm dengan tekanan pengepresan 7 metrik ton. Analisis biobriket meliputi uji kuat tekan, uji densitas dan relaksasi, uji kadar air, kadar abu, uji zat terbang, uji karbon tetap dan uji nilai kalor. Hasil yang diharapkan dalam penelitian ini ialah memberikan nilai jual yang tinggi pada batubara tingkat rendah dan menjadi salah satu alternatif produk bahan bakar padat dan ramah lingkungan yang dapat digunakan oleh masyarakat untuk keperluan memasak. Berdasarkan hasil pengujian, biobriket terbaik memiliki ukuran partikel 60 mesh. Hasil yang diperoleh menunjukkan bahwa ukuran partikel terbaik berada pada pencampuran batubara dan ubi karet dengan rasio 9 : 1, jumlah nilai kalor tertinggi mencapai 5146 Kkal/kg.Kata kunci: batubara, biobriket, biomassa, uji mekanik, uji sifat fisik

Maka pada penelitian ini, karakteristik perpindahan panas akan dianalisis dengan membandingkan antara tube bank inline dan tube bank stagger dan digunakan pendekatan secara numerik dua dimensi dengan bantuan software ansys fluent. Penyelesaian secara numerik dilakukan dengan menggunakan metode elemen hingga atau finite elemen method, dan disimulasikan dengan menggunakan model K-Omega SST. Hasil simulasi menunjukkan visualisasi berupa kontur kecepatan dan distribusi temperatur dan grafik perbandingan temperatur dan kecepatan antara tube bank inline dan tube bank stagger untuk mempermudah pengamatan karakteristik perpindahan panas. Hasil penelitian menunjukkan temperatur output rata-rata tube bank inline memiliki nilai sebesar 1235,670C dan tube bank stagger sebesar 1170,70C. Nilai kecepatan rata-rata tube bank inline sebesar 72,87 m/s dan tube bank stagger sebesar 59,15 m/s.maka dapat disimpulkan bahwa tube bank stagger mengalami perpindahan panas yang lebih maksimal bila dibandingkan dengan tube bank inline.
