Creator An entity primarily responsible for making the resource Nanang Susanto Description An account of the resource Ketersediaan pasokan gas bumi menjadi faktor kunci dalam menggerakkan kegiatan operasi berbagai industri. Pemanfaatan gas bumi dalam negeri cenderung meningkat dan diperkirakan akan mengalami defisit pada tahun 2022 jika tidak menemukan sumber gas bumi baru. Berbagai upaya dilakukan oleh pemerintah dalam menghadapi ketersediaan gas dalam negeri, baik mencari sumur-sumur gas baru, maupun mengubah bahan bakar padat batubara menjadi gas. Dalam penelitian ini kajian yang dilakukan adalah proses pirolisis batubara muda Aceh dengan menggunakan pereaksi nitrogen (N2) sebagai gas dasar. Metodologi yang digunakan untuk mengkaji karakteristik dasar pirolisis batubara meliputi penurunan massa dan komposisi gas yang dihasilkan selama pirolisis. Penurunan massa selama pirolisis dikaji dengan dapur pemanas listrik sedangkan komposisi gas dikaji dengan menggunakan gas chromatography (GC). Penelitian ini dilakukan pada temperatur dengan variasi 160 oC, 180 oC, 200 oC, dan 400 oC. Hasil penelitian ini menunjukkan bahwa semakin tinggi temperatur pirolisis maka laju penurunan massa semakin besar. Potensi kandungan senyawa gas H2 tidak terbentuk selama proses pirolisis pada temperatur 160 oC 180 oC, 200 oC, sedangkan pada temperatur 400 oC berpotensi terbentuknya H2 yaitu 1,19%.

INDRA RIAYATSYAH Date A point or period of time associated with an event in the lifecycle of the resource 2013 Description An account of the resource Pemanfaatan energi surya sebagian besar untuk pemanas air. Sistem pemanas air surya sudah umum digunakan namun masih memiliki beberapa hambatan sehingga selalu diperlukan penelitian untuk meningkatkan kinerja sistem pemanas air surya. Pada penelitian ini telah dirancang pemanas air surya yang dapat diandalkan untuk menyediakan air panas pada saat tidak tersedianya energi matahari atau sinar surya dalam jangka pendek. Pemanas air surya yang dirancang dan dibuat berukuran panjang 465 mm x 365 mm x 15 mm. Untuk meningkatkan kinerja sistem digunakan material penyimpan energi panas (PCM) diletakkan didalam kolektor surya yang berbentuk bola-bola. Material yang digunakan untuk penyimpan energi panas yaitu lilin lebah (beeswax). Pengujian sistem pemanas air surya dilakukan dilingkungan Fakultas Teknik Universitas Syiah Kuala dengan kondisi cuaca Kota Banda Aceh. Dari hasil pengujian diperoleh sistem pemanas air surya mampu mencapai 58C, penggunaan material penyimpan energi panas mampu mempertahankan temperatur air yang telah diganti berkisar antara 40C hingga 45C selama 2-3 jam, sedangkan radiasi surya dan temperatur ruang kaca mulai menurun. Dari hasil penelitian ini dapat disimpulkan bahwa menggunakan material berubah fasa (PCM) sebagai material penyimpan energi panas akan mampu meningkatkan dan mempertahankan kinerja sistem pemanas air surya.

After it is donated by the donor, the blood will be stored in a storage cabinet until it is needed by the patient. One of the common ways to preserve and maintain the chemical and structural changes of the blood is to store it in a storage area that has a temperature of between 1-6 °C. Blood storage cabinets that already exist this days, use the vapour compression cycle which is only suitable for the storage of large capacity and is not portable if there is blood demand in remote areas. To answer these problems, in this research will be designed and manufactured portable blood storage cabinet by the size of 30 cm x 30 cm x 30 cm. The heat in the storage is discharged to the air by using a heat pump which works using thermoelectric cooler (Peltier effect). The Peltier effect occurs when two metals or semi-conductors of different materials are connected and energized that there will be a difference in temperature. In order to test the feasibility of the blood storage cabinets technically, the heat transfer study is conducted. The experimental result shows that the expected temperature is achieved.

An experimental unit consisted of data acquisition, the heat exchanger shell and tube were used to improve heat transfer. The fluid heat pipe was designed in longitudinal fin and radial fin. Paraffin wax was used as a thermal storage medium. The characteristics of heat transfer from fluid to paraffin wax is investigated in different heat flux conditions. The experimental results show that the heat transfer characteristics show similarities to the heat exchanger tubes. In the preheating process, it is dominated by conduction, but at the melting temperature of the heat transfer, it is dominated by convection. The use of longitudinal finned pipe has been able to increase the heat transfer rate.

Creator An entity primarily responsible for making the resource Herry Fahriza Juardi Description An account of the resource Kemampuan tanaman merupakan kemampuan penyerapan emisi gas CO2 dan panas matahari untuk mengurangi dampak pemanasan global. Pemanasan global merupakan meningkatnya temperatur rata-rata atmosfer bumi yang berdampak pada perubahan iklim, mencairnya es di Kutub, serta naiknya permukaan air laut. Penyebab terjadinya pemanasan global ini adalah terhambatnya transfer panas dari permukaan bumi ke ruang angkasa yang sering dianalogikan seperti efek rumah kaca. Terjadinya efek rumah kaca dikarenakan adanya gas rumah kaca karbon dioksida (CO2) dan gas lainnya di atmosfer bumi. Dengan meningkatnya konsentrasi gas salah satunya CO2, semakin banyak pula panas yang terperangkap dibawahnya. Peningkatan konsentrasi CO2 terjadi karena tidak seimbangnya antara peningkatan dengan penyerapan CO2 di atmosfer, hal ini disebabkan meningkatnya pemakaian energi fosil dan terus berkurangnya hutan-hutan penyerap CO2 akibat penebangan, pembakaran, dan alih fungsi lahan. Untuk mengurangi peningkatan gas CO2, salah satu upaya yang dapat dilakukan yaitu memperbanyak tanaman penyerap CO2, karena tanaman mampu menyerap CO2, mengubahnya menjadi oksigen dan glukosa dengan memanfaatkan panas matahari. Tujuan penelitian ini adalah untuk mengetahui kemampuan penyerapan CO2 dari beberapa jenis tanaman. Pengujian dilakukan menggunakan 2 ruang uji tertutup dengan dimensi 100 cm x 50 cm x 50 cm, dimana ruang I digunakan untuk penyimpanan emisi gas buang CO2 sebanyak 0.5%, sedangkan ruang II sebagai tempat tanaman yang akan diuji. Pengaliran gas ke ruang II, dilakukan dengan bantuan fan selama 300 menit, dan pengambilan data dilakukan setiap 60 menit. Dari hasil penelitian, dapat diurutkan kemampuan tanaman menyerap CO2 terbaik yaitu: palem ekor tupai: 0.25 milligram/m2.jam, kemudian trembesi: 0.243 milligram/m2.jam, mahoni: 0.2 milligram/m2.jam, jeruk purut: 0.177 milligram/m2.jam, mangga: 0.166 milligram/m2.jam dan tanjung: 0.166 milligram/m2.jam.

Dalam pembuatan kertas saat ini umumnya bahan baku yang digunakan berupa bambu, kenaf, dan lain lain. Tetapi lahan untuk menanam pohon yang menghasilkan bahan baku kertas tersebut semakin menipis disebabkan oleh banyaknya lahan yang dialih fungsikan menjadi perkebunan sawit, perkebunan karet perumahan dan pembalakan liar (Illegal logging). Tujuan penelitian ini, membuat kertas alternatif dari alga merah (Gracilaria sp) dengan penambahan serat batang rubik (C. Gigantea) untuk mengatasi menipisnya ketersedian bahan baku bambu, kenaf, dan lain-lain sebagai bahan baku pembuatan kertas serta mengkaji sifat termal dari kertas tersebut. Kertas dibuat dengan mengekstraksi serat batang rubik, membuat pulp dengan memvariasikan jumlah persentase serat dengan alga (0%, 2%, 4%, 6%, 8%), membuat kertas dalam cetakan 25 cm x 30 cm. Hasil penelitian menunjukkan nilai optimun konduktivitas termal diperoleh pada variasi serat batang 6%. Namun hasil konduktivitas termal yang paling tinggi terletak pada variasi 0% serat batang rubik, sedangkan paling kecil adalah pada variasi 4% serat batang rubik karena perbedaan temperatur yang besar. Semakin besar perbedaan temperatur maka semakin rendah nilai konduktivitas termalnya dan sebaliknya.Kata Kunci : Kertas, Alga Merah, Serat Batang Rubik, Konduktivitas Termal.
