Abstract

Yasar et al, 2017. Prediction of Ground Water Potential for Optimization of Rainfed Rice Field in Supporting Food Security. JLSO 6(2):170-175.In Simeulue Island, that has the existed paddy field and generally of that is  rainfed. Recently, to irrigate the paddy field with that percentage is expected enough by natural meet of the necessity of paddy field by receiving the potential precipitation. However, rising of the climate change has caused paddy field activity is not fully runned by only utilizing the precipitation and utilizing the surface water, as irrigatiom water resource is not possible because of geological difficulty. This article aims to find a breakthrough related to the problem of irrigation water insufficiency through utilization of natural resource potency in Simeuleu Island. Presenting is descriptively done using primary data by way of field measurement and literature review to obtain a beneficiary of groundwater as irrigation water resource. Data acquiring in this research uses geoelectrical method by setting the Wanner-Schlumberger configuration of Resistiviti meter ARES. Data were obtained from one spread that was east-west oriented by having 460 m spread length and 20 m spacing interval. The coordinate of spread is at initial point N 02°25’14.2”/E 96°18’12.2” and at final point N 02°25’43.9”/E 96°18’27.1. Based on the 2D resistivity cross section shows that Situbok village (STB) is generally obtained a low resistivity value which is 2-100 Ωm in range and dominantly expected as alluvium. Low resistivity value can be estimated as a conductive layer (aquifer) which commonly consists of groundwater. On the cross section of resistivity value, the conductive layer is the layer which has the resistivity value less than 16 Ωm and laterally and vertically is existed at 240-360 m and 45-94 m, respectively.

Abstract

The backwardness of Muslims civilization today support to reflection in an attempt to find a way towards a revival. One was taken to the efforts is reinterpretation of Islamic texts (Koran) in accordance with the spirit of this time. Efforts are being made to the hermeneutic method is commonly called contextualization, complement some of the approaches that have been there before. In this paper the authors conclude that the tradition of critical thinking, creative and innovative to do with getting rid of prejudice and negative assumptions, and rationality. Therefore, efforts to understand the Qur'an with various new methodological approaches should be developed and should not stop at one point.

Abstract

Pantai Lhok Seudu terletak pada perlintasan jalan raya Banda Aceh - Meulaboh yangberjarak ±20 km jika ditempuh dari Kota Banda Aceh. Pantai Lhok Seudu terletak diKecamatan Leupung Kabupaten Aceh Besar. Letak strategis pantai Lhok Seudu yang beradadi perlintasan Barat-Selatan Aceh dengan Timur-Utara Aceh merupakan suatu potensi besaruntuk pengembangan sektor ekonomi. Potensi lain, Lhok Seudu secara umum merupakansalah satu destinasi wisata yang indah di Provinsi Aceh. Pengolahan ikan selama iniumumnya dengan metode pengeringan alami. Permasalahan yang dihadapi dengan sistempengeringan konvensional antara lain; sangat tergantung pada cuaca, ketika cuaca mendungdan musim penghujan, pengeringan tidak bisa dilakukan sehingga produk olahanterbengkalai. Pengeringan dengan sistem terbuka juga seringkali mendapat gangguan sepertiburung, kucing dan selanjutnya kontaminasi debu juga tid ak dapat dihindari, sehinggaproduk yang dihasilkan kurang higienis. Solusi yang tepat dari permasalahan tersebut adalahpenggunaan alat pengering tipe efek rumah kaca yang telah dinamakan dengan GHE Vent.dryer (Green House Effect Ventilator dryer). Tujuan penelitian ini adalah mengaplikasikandan evaluasi performansi alat pengering ikan GHE Vent. dryer pada proses pengeringan ikansebagai produk unggulan daerah Pantai Lhok Seudu Kecamatan Leupung Kabupaten Aceh Besar.Metode pelaksanaan kegiatan penelitian ini dilakukan dengan pendekatan eksperimen yangdiawali dengan persiapan alat dan bahan (GHE Vent. dryer dan ikan), kemudian diikutidengan proses pengeringan ikan secara konvensional dan penggunaan GHE Vent. dryer.Selanjutnya, kegiatan dilanjutkan dengan pengamatan waktu dan kapasitas pengeringan.Hasil kajian menunjukkan bahwa pengeringan menggunakan GHE Vent. dryer dapatmempersingkat waktu pengeringan dan produk yang dihasilkan lebih hiegenis.

Abstract

Abstrak. Green house effect (GHE) vent dryer adalah alat pengering dengan memanfaatkan energi surya sebagai sumber energi pengeringan. Namun radiasi matahari terbatas pada waktu tertentu sehingga mengganggu prases pengeringan. Penambahan lilin sebagai media penyimpan panas adalah salah satu solusi agar alat  green house effect (GHE) vent dryer dapat beroperasi pada saat energi surya sudah meredup. Tujuan penelitian ini untuk menguji kinerja GHE Vent Dryer dengan menggunakan lilin sebagai media penyimpan panas. Data yang diukur dalam penelitian ini berupa suhu di dalam  ruang pengering (ruang 1, ruang 2 dan ruang 3), ruang absorber, suhu lingkungan dan kecepatan udara. Pengukuran dimulai dari pukul 08.00 WIB sampai sahu didalam ruangan menyamai suhu lingkungan, proses pengukuran dilakukan setiap 60 menit. Hasil penelitian ini didapatkan bahwa rata-rata suhu absorber menggunakan lilin sebagai media penyimpan panas berkisar 31 ºC sampai 71 ºC dengan temperatur lingkungan yang di hasilkan 27 ºC sampai 35 ºC dan untuk terperatur dalam alat pengering sekitar 27 ºC sampai 58 ºC. Hasil pengukuran kecepatan udara pada penelitian ini berkisar 0,3 m/s sampai 1,5 m/s. Dapat disimpulkan bahwa penggunaan batu serpihan sebagai media penyimpan panas pada alat GHE vent Dryer mampu mempertahankan panas pada ruang pengering selama 4 sampai 5 jam saat tidak ada radiasi matahari. Performance Of Ghe Vent Dryer By Using Wax As Heat StorageAbstract. Green house effect (GHE) vent dryer is a dryer that uses solar energy as a drying energy source. However, solar radiation is limited to a certain time so that it interferes with the drying process. The addition of wax as a heat storage medium is one solution so that the green house effect (GHE) vent dryer can operate when the solar energy has dimmed. The purpose of this study was to test the performance of the GHE Vent Dryer using wax as a heat storage medium. The data measured in this study were the temperature in the drying chamber (room 1, room 2 and room 3), absorber chamber, ambient temperature and air velocity. The measurement starts from 08.00 WIB until the temperature in the room equals the ambient temperature, the measurement process is carried out every 60 minutes. The results of this study found that the average temperature of the absorber using wax as a heat storage medium ranged from 31 C to 71 C with an ambient temperature of 27 C to 35 C and for a temperature setting in the dryer it was around 27 C to 58 C. The results of air velocity measurements in this study ranged from 0.3 m/s to 1.5 m/s. It can be concluded that the use of crushed stone as

Abstract

Tanah adalah media dan sumber daya alam terpenting untuk pertumbuhan dan perkembangan tanaman. Tanaman dapat tumbuh ketika tanah dengan kondisi baik, sehat dan subur. Tujuan penelitian ini adalah mengkaji karakteristik sifat elektro-optik dari tanah berdasarkan spektrum near infrared agar menghasilkan informasi panjang gelombang relevan dengan nutrisi atau properties kimia tanah. Hasil penelitian menunjukkan bahwa rentang panjang gelombang relevan untuk menggambarkan properties dan nutrisi tanah seperti ikatan O-H yang terdapat pada panjang gelombang 5250 – 5261 Cm-1, 5843 – 5854 Cm-1, C-H pada panjang gelombang 5696– 5715 Cm-1 , 7443 – 7509 Cm-1.Analysis of Soil Spectrum Characteristics Based on Near Infrared SpectroscopySoil is the most important medium and natural resource for plant growth and development. Plants can grow when the soil is in good, healthy and fertile conditions. The purpose of this study was to examine the characteristics of the electro-optical properties of the soil based on the near infrared spectrum in order to produce wavelength information relevant to the nutrient or chemical properties of the soil. The results showed that the wavelength range is relevant to describe soil properties and nutrients such as O-H bonds found at wavelength 5250 – 5261 Cm-1, 5843 – 5854 Cm-1, C-H at wavelength 5696 – 5715 Cm-1 , 7443 – 7509 Cm-1
