Lengkuas (Alpinia galanga) adalah salah satu tanaman penting bagi masyarakat Indonesia. Tanaman ini dapat digunakan untuk bumbu masakan dan obat herbal. Tujuan kajian ini adalah untuk menduga umur simpan lengkuas segar dengan menggunakan model Arrhenius. Lengkuas segar yang baru dipanen dibersihkan dan dipotong-potong dengan ukuran 2cm, kemudian disimpan pada suhu 5, 10 dan 28°C. Evaluasi dilakukan oleh 25 orang panelis dengan menggunakan skala hedonic dari sangat suka sampai sangat tidak suka terhadap warna, kesegaran, aroma dan tekstur. Parameter yang diamati adalah kadar air dan kadar sari larut dalam air. Parameter tersebut diamati dalam interval 3 hari selama 21 hari atau sampai sampel dinyatakan tidak disukai oleh panelis pada salah satu kriteria hedoniknya. Hasil penelitian menunjukkan bahwa pad asuhu 28°C, lengkuas dapat disimpan selama 3 hari, sedangkan pada suhu 10 dan 5°C, lengkuas dapat disimpan selama 12 dan 21 hari. Energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar sari larut dalam air lebih besar dari energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar air lengkuas. Namun demikian, kedua parameter tersebut tidak tepat digunakan untuk menduga umur simpan lengkuas. Shelf-Life Prediction of Galanga by Using Arrhenius Model Based on Its Moisture and Water Soluble Extract Content Abstract. Galanga (Alpinia galanga) is one of important plants for Indonesian people. It can be used as spices and also as herbal medicine. The aim of this study is to predict the shelf-life of fresh galanga by using Arrhenius model. Fresh harvested galanga, which was cleaned and chopped at width about 2 cm, was stored at temperatures 5, 10, and 28°C. The evaluation was done by 25 respondents by using hedonic scale from the range of like very much until dislike very much. This hedonic evaluation was assessed, based on colour, freshness, aroma, and texture. Parameters observed were moisture and water soluble extract content. These parameters observed at interval 3 days for 21 days or until the samples were rejected by respondents for at least one of hedonic factors. Results showed that at temperature 28°C, galangal can be stored for 3 days. However, at temperature 10 and 5 °C, galangal can be stored for 12 and 21 days, respectively. The energy act ivation (EA) and the rate of quality change (Q10) due to water soluble extract were higher than those of water content. Nevertheless, these two parameters cannot be used in prediction the shelf-life of fresh galanga.

Interception of rain is the retention of rainwater on surface vegetation before it evaporates back into the atmosphere. Research relating to the interception is still lacking, so it is necessary to study the interception on some types of plants. Although the interception had a little value, and sometimes overlooked, but in some plants have a considerable effect. The purpose of this study was to determine the magnitude of interception in Mahogany and Pine trees, as well as to determine the relationship between rainfall and interception. In this study, samples taken at the Mahogany and Pine trees by the number of 3 samples of each tree. There were two approaches to measure the amount of interception, the first approach was the Volume Balance Approach and the second approach was the Energy Balance Approach. In this study, the volume balance approach, with measurements of rainfall, throughfall, stemflow and interception for ten days of rainfall. The average amount of interception Mahogany obtained 15.5 mm (7.31%) of the total amount of rainfall and the correlation coefficient (r) was at 0.554. While the average number of interception Pinus acquired 87.23 mm (41.15%) of the total amount of rainfall and the correlation coefficient (r) was at 0.505. The size of the interception was influenced by wind speed, density and canopy shape. The research obtained that the interception for pine trees was higher than Mahogany trees. The results also showed that the higher percentage of rainfall, the smaller interception. This was due to the canopy conditions and climatic factors.   Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RTP/article/view/235 10.17969/rtp.v5i2.235 Language A language of the resource eng Publisher An entity responsible for making the resource available Program Studi Teknik Pertanian, Fakultas Pertanian, Universitas Syiah Kuala Relation A related resource http://jurnal.unsyiah.ac.id/RTP/article/view/235/221 Source A related resource from which the described resource is derived Rona Teknik Pertanian; Vol 5, No 2 (2012): Volume 5, No. 2, Oktober 2012; 368-372 2085-2614 2085-2614 Subject The topic of the resource interception; rainfall, throughfall; stemflow; Mahogany; Pine trees Title A name given to the resource Perbandingan Nilai Intersepsi Pohon Mahoni (Swietania mahagoni) dan Pohon Pinus (Casuarina cunninghamia) Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Model hidrologi Soil and Water Assessment Tool (SWAT) telah digunakan untuk mensimulasikan debit Sub DAS Krueng Meulesong yang terletak di Kabupaten Aceh Besar menggunakan data klimatologi aktual dan data klimatologi prediksi. Data klimatologi aktual diperoleh dari stasiun klimatologi terdekat sedangkan data prediksi merupakan data hasil perkiraan dari Climate Forecast System Reanalysis (CFSR) yang dilaksanakan oleh National Centers for Environmental Prediction/Environmental Modeling Center (NCEP/EMC) yang tersedia di 4 stasiun di sekitar Sub DAS. Pada awalnya model mensimulasikan debit dari Sub DAS menggunakan input data klimatologi aktual yang hasilnya dikalibrasikan dengan data debit tercatat pada pos duga air. Model dengan parameter terbaik kemudian digunakan untuk mensimulasikan tiga skenario simulasi menggunakan data input klimatologi hasil prediksi, adapun skenarioskenario tersebut adalah (1) data dari satu stasiun terdekat, (2) data dari dua stasiun terdekat dan (3) data dari empat stasiun terdekat. Hasil kalibrasi model menunjukkan bahwa model memiliki kinerja cukup baik dengan nilai koefisien determinasi 0.67 dan koefisien Nash-Sutcliffe 0.37. Aplikasi data klimatologi hasil prediksi menunjukkan bahwa, data prediksi dari satu stasiun terdekat menghasilkan kinerja model yang lebih baik. Sementara itu semakin banyak stasiun yang digunakan sebagai input data akan menghasilkan hasil simulasi yang semakin mendekati hasil simulasi dengan menggunakan data aktual.SWAT Model Application To Simulate Discharge From Krueng Meulesong Sub Watershed Using The Actual And Predicted Climatological DataABSTRACT. The Soil and Water Assessment Tool (SWAT) hydrological model was used to simulate discharge from Krueng Meulesong subwatershed located in Aceh Besar District using actual and predicted climatological data. The actual data were collected from the nearest local meteorological station while the predicted data was the results of Climate Forecast System Reanalysis (CFSR) completed by National Centers for Environmental Prediction/Environmental Modeling Center (NCEP/EMC) through four stations located around the subwatershed. The model was initially developed using actual data and then calibrated with observed streamflow data. The best model then was rerun using 3 scenarios of predicted data i.e. (1) data from the nearest station, (2) data from average of the two nearest stations and (3) data from average of four nearest stations. The model performance was categorized into satisfactory with determination and Nash-Sutcliffe coefficients were 0.67 and 0.37, respectively. Comparing the model performance resulted from predicted data suggested that using the nearest station data would produce a better model performance. Meanwhile, incorporating more predicted data stations around subwatershed would cause the model to produce simulated streamflow similar to the streamflow using the actual data.

Drying is one of the most important process in producing a good quality of rosella tea. The study was aimed to evaluate the drying efficiency of rosella tea by using a cabinet dryer. The source of energy for the dryer was from the burning of charcoal. The charcoal was prepared from the coconut shell since it was abundant biomass product. About 7.5 kg of fresh rosella flower was dried for 17 hours. The total of charcoal consumed was 17 kg. The moisture content of rosella flower was reduced from 90 to 12 %. The analysis showed that the total of energy produced from the burning of 17 kg charcoal was 309.4 MJ, whilst the total energy needed to dry the flower was 15,72 MJ. Therefore, the drying efficiency was still low about 4.58%. Further study is recommended to improve the drying efficiency for example by the use of deeper depth of dried products between 2 and 6 cm as well as by improving the system of hot air circulation.  Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RTP/article/view/234 10.17969/rtp.v5i2.234 Language A language of the resource eng Publisher An entity responsible for making the resource available Program Studi Teknik Pertanian, Fakultas Pertanian, Universitas Syiah Kuala Relation A related resource http://jurnal.unsyiah.ac.id/RTP/article/view/234/220 Source A related resource from which the described resource is derived Rona Teknik Pertanian; Vol 5, No 2 (2012): Volume 5, No. 2, Oktober 2012; 364-367 2085-2614 2085-2614 Subject The topic of the resource cabinet dryer; drying, efficiency; rosella Title A name given to the resource Analisis Efisiensi Pada Sistem Pengeringan Bunga Rosella (Hibiscus sabdariffa L) Menggunakan Alat Pengering Tipe Lemari Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Penelitian ini bertujuan untuk: (1) mengevaluasi kesesuaian alokasi ruang RTRW Kabupaten Aceh Barat tahun 2012- 2031 dengan alokasi penetapan kawasan hutan Kabupaten Aceh Barat berdasarkan SK Menhutbun No. 170/Kpts- II/2000, dan (2) mengevaluasi penyimpangan penggunaan lahan eksisting Kabupaten Aceh Barat tahun 2012 dengan RTRW Kabupaten Aceh Barat tahun 2012-2031 dan (3) membahas secara umum penyebab dari penyimpangan penggunaan lahan dan dampak yang ditimbulkannya. Penelitian ini dilaksanakan dari bulan Maret 2012 hingga Februari 2013 di Kabupaten Aceh Barat dan di Laboratorium Penginderaan Jauh dan Kartografi Fakultas Pertanian Universitas Syiah Kuala. Penelitian ini menggunakan metode deskriptif dengan mengumpulkan berbagai data sekunder dan primer yang diperlukan dan analisis tumpang tindih peta (overlay) serta cek lapangan (ground check) penggunaan lahan terkini. Hasil penelitian menunjukkan terjadi penyimpangan alokasi ruang RTRW Kabupaten Aceh Barat tahun 2012-2031 terhadap kawasan hutan Kabupaten Aceh Barat yang ditetapkan dalam SK Menhutbun No. 170/Kpts- II/2000 seluas 6.663,45 ha (2,41%). Penggunaan lahan eksisting Kabupaten Aceh Barat tahun 2012 juga menunjukkan terjadi penyimpangan terhadap alokasi ruang RTRW Kabupaten Aceh Barat tahun 2012-2031 yaitu seluas 25.319,21 ha (9,16%). Secara umum faktor penyebab terjadinya penyimpangan penggunaan lahan adalah pemekaran kabupaten/kota, pengembangan infrastruktur wilayah, pengembangan usaha perkebunan dan pertambangan. Penyimpangan penggunaan lahan tersebut berdampak kepada semakin luasnya deforestasi, meningkatnya koefisien limpasan dan frekuensi banjir.Deviation of Land Use Based on Spatial Planning of West Aceh DistrictAbstract. This study aimed to: (1) evaluate the suitability of spatial allocation of space in West Aceh district from 2012 to 2031 with the allocation of forest establishment of West Aceh by Decree of Menhutbun No. 170/Kpts-II/2000, (2) evaluate the deviation of the existing land use of West Aceh district in 2012 with the Spatial West Aceh district of 2012-2031, and (3) discuss generally the cause of the deviation and the impact of land use. This study was conducted from March 2012 to February 2013 in the West Aceh district, and at the Laboratory of Remote Sensing and Cartography, Faculty of Agriculture, Kuala University. This research used descriptive method by collecting a variety of secondary and primary data necessary, analysis of overlap maps and ground check for evaluating the current land use. The results showed deviations spatial space allocation of West Aceh District of 2012-2031 to West Aceh forests set out by Decree of Menhutbun No.170/Kpts-II/2000 was 6,663.45 Ha (2.41%). Furthermore, the deviation of existing land use of West Aceh district in 2012 to the spatial allocation of the West Aceh district of 2012-2031 was 25,319.21 Ha (9.16%). In general, the causes of deviation were the division of districts, development of region infrastructure, plantation and mining development. The land use deviations would affect the extent of deforestation, the increasing of runoff coefficients and frequency of floods.

Ubi kayu merupakan salah satu tanaman yang mengandung karbohidrat. Ubi kayu dapat dikeringkan untuk mendapatkan produk olahan contohnya pembuatan tepung dan gaplek. Pada penelitian ini dilakukan modifikasi pengering surya dengan menambahkan kincir angin savonius sebagai penggerak kipas pada pengering tersebut yang bertujuan untuk memaksimalkan sirkulasi udara didalam ruang pengering. Parameter yang dilakukan diantaranya pengukuran kecepatan udara, distribusi temperatur, kelembaban relatif, iradiasi surya dan pengukuran kadar air. Dengan penambahan kincir angin savonius, kecepatan udara di dalam pengering surya lebih stabil bila dibandingkan dengan kecepatan udara di lingkungan. Temperatur di dalam ruang pengering lebih tinggi dari pada temperatur lingkungan, sedangkan kelembaban relatif di dalam pengering lebih rendah dibandingkan dengan di lingkungan. Hal ini menyebabkan proses pengeringan berlangsung cepat. Nilai iradiasi surya yang didapat berfluktuasi. Iradiasi tertinggi diperoleh pada hari kedua penelitian yaitu 595 W/m2. Kadar air awal ubi kayu yaitu 61,7 %. Kadar air akhir yang diperoleh rak A5 yaitu sebesar 11,7% dan rak B1 yaitu sebesar 12,9% sudah mendekati kadar air yang diharapkan untuk  pembuatan tepung yaitu 12%. Performance of Solar Dryer by Using Savonius Windmill for Cassava (Manihot esculenta) DryingAbstract. Cassava is one of the plants that contain carbohydrates. Cassava can be dried to produce processed products such as cassava flour and “gaplek”. In this research, the solar dryer was modified by adding a savonius windmill as fan drive which aims to maximize the air circulation inside the drying chamber. The observed parameters include air velocity, the distribution of temperature, relative humidity, solar irradiation and the water content. The addition of savonius windmill caused the air velocity in the solar dryer was more stable when compared to the speed of the air in the environment. Moreover, the temperature in the drying chamber was higher than the ambient temperature, while the relative humidity in the dryer was lower than in the environment. As a result, it caused rapid drying process. Solar irradiation values obtained fluctuate. The highest irradiation was obtained on the second day of the study (595 W / m2). The moisture content of the cassava decreased from  61.7% to 11.7% (at A5 rack) and 12.9% (at B1 rack). Those values was approaching the expected flour water content (12% ).
