Optimalisasi Kombinasi Pupuk Untuk Perencanaan Hasil Panen Padi Menggunakan Metode Fuzzy Goal Programming

Semakin pesatnya perkembangan jumlah penduduk di Indonesia, berpengaruh pada persediaan beras yang harus ditingkatkan dengan cara pengelolaan pertanian yang baik sehingga diperoleh produksi padi yang tinggi. Oleh karena itu,petani membutuhkan kombinasi takaran pupuk yang tepat seperti Nitrogen (N), Phosphorus (P), dan Kalium (K) untuk memperoleh hasil panen yang tinggi dan meminimalkan biaya pengeluaran untuk pupuk. Model kombinasi pupuk dan manajemen hara dengan toleransi berdasarkan pendekatan Hannan (Chih-Sheng dan Ching-Gung, 1997) dengan dua variabel tingkat pencapaian untuk model Fuzzy Goal Programming (FGP) dengan beberapa tujuan, yaitu memaksimalkan hasil panen padi dan meminimalkan biaya pengeluaran pupuk. Tujuan Fuzzy dikonversi ke kendala tujuan yang diperoleh dengan menggunakan hubungan nilai fungsi keanggotaan model fuzzy. Didapatkan hasil panen padi yang maksimal yaitu sebesar 28083,468 kg/ha dalam empat kali masa panen atau dengan kata lain 7020,867 kg/ha sekali panen dengan biaya pupuk dapat diminimalkan sebesar Rp 267.970,6

PERANAN MEDIA PENGAJARAN DALAM MENINGKATKAN PRESTASI BELAJAR MATA PELAJARAN FIQIH DI MADRASAH IBTIDAIYAH NEGERI 1 PESAWARAN

Dalam dunia pendidikan media pengajaran mempunyai peranan yang sangat penting bukan saja untuk memudahkan dalam penerimaan materi yang diajarkan oleh guru selain itu akan mempermudah guru dalam menyampaikan materi pelajaran. Kehadiran media pengajaran dalam proses belajar mengajar tetap memegang peranan penting karena media pengajaran sangat dibutuhkan untuk merangsang, dan memberi fasilitas belajar bagi siswa untuk mencapai tujuan yang diinginkan. Dengan menggunakan media pengajaran secara tepat dan bervariasi, maka dapat diatasi sikap pasif anak-anak didik. Dalam hal ini media pengajaran berguna untuk menimbulkan kegairahan belajar, memberi rangsangan untuk memotivasi siswa, sehingga diharapkan prestasi belajar siswa akan menjadi lebih baik lagi. Untuk itu penulis mencoba untuk mengkaji fenomena yang terjadi di MIN 1 Pesawaran dimana Guru Fiqih telah menggunakan media pembelajaran dengan baik, akan tetapi prestasi belajar siswa mata pelajaran Fiqih masih ada yang belum tuntas hal inilah yang menarik perhatian penulis untuk meneliti lebih lanjut bagaimana peranan Media pengajaran dalam meningkatkan prestasi belajar. Dalam penelitian ini penulis merumuskan masalah sebagai berikut : Bagaimanakah peran Media Pengajaran dalam meningkatkan prestasi belajar Fiqih di MIN 1 Pesawaran? Adapun tujuan dari penelitian ini adalah mengetahui Media Pengajaran apa saja yang digunakan dalam menyampaikan pelajaran Fiqih dan bagaimana prestasi belajar Fiqih di MIN 1 Pesawaran. Penelitian ini termasuk dalam jenis field research atau penelitian lapangan sebagai pendekatan luas dalam penelitian kualitatif, yakni penelitian yang digunakan untuk mencari data yang berasal dari lapangan, juga data hasil wawancara, dokumentasi dan observasi yang diperoleh melalui pencatatan apa adanya tentang kondisi obyektif yakni metode yang digunakan untuk membuat generalisasi, kemudian dianalisa dengan menggunakan metode deskriptif analisis. Dari penelitian yang dilakukan, dapat dijelaskan hal-hal sebagai berikut; Pertama Peran Media pembelajaran dalam meningkatkan prestasi belajara siswa adalah dengan 1) Memperjelas penyajian pesan agar tidak terlalu verbalistis, 2) Mengatasi keterbatasan ruang, waktu dan daya indera dimana objek yang terlalu besar, bisa digantikan dengan gambar; Objek yang kecil-dibantu dengan proyektor mikro; Gerak yang terlalu lambat atau terlalu cepat, dapat dibantu dengan timelapse; Kejadian atau peristiwa yang terjadi di masa lalu bisa ditampilkan lagi lewat rekaman film; Objek yang terlalu kompleks dapat disajikan dengan model, dan Konsep yang terlalu luas dapat di visualkan dalam bentuk film, 3) Menggunakan media pengajaran secara tepat dan bervariasi, maka dapat diatasi sikap pasif anak-anak didik dan 4) Mempersamakan pengalaman, memberi persepsi yang sama dan memberikan rangsangan yang sama. Kedua, prestasi belajar siswa sudah baik karena dari kelas yang penulis teliti yakni kelas III s/d kelas V didapat hasil bahwa siswa yang mendapat nilai baik yakni antara 90 – 100 ada 143 siswa atau 39,72%, mendapat nilai 75 – 90 ada 194 siswa atau 53,89 persen dan hanya 23 siswa atau 6,39% siswa yang mendapat nilai kurang dari 75

Identifikasi Kenyamanan Termal Bangunan (Studi Kasus: Ruang Kuliah Kampus Ipb Baranangsiang Dan Darmaga Bogor)identification of Building Thermal Comfort (Case Study: Classrooms in Ipb Banangsiang and Darmaga Campuses)

Housing development, well-planned or not well-planned, has changed urban view and its thermal environment. Many researchers have claimed that the worse quality of urban thermal environment is proportional to physical development of the city. Physical development in urban areas has caused various environmental problems, one of them is the change in quality of thermal environment by which the city becomes hotter than the surrounding areas. The purpose of this research was to identify thermal comfort either in classrooms at Darmaga or Baranangsiang campuses of Bogor Agricultural University. PMV (Predicted Mean Vote), using the boundary Effective Temperature (TE), THI (Temperature Humidity Index), and the last method is respondent test. PMVs (Predicted Mean Votes) in the classrooms at Baranangsiang campuses are thermally neutral to slightly warm, while that in classrooms in Darmaga campus are warmer. Effective Temperature which is resulted in the both of lecture halls are comfortable warm conditions. In addition, for respondents test, the thermal impression in IPB campus of Baranangsiang prefers to choose the slightly warm conditions, but for a lecture hall in campus of IPB Darmaga is more dominated by warm and slightly warm conditions. The questionnaire has been appropiated to the range of PMV index. So, the lecture halls that have been studied in both of campus can be concluded as slightly warm condition, because the thermal impressions felt by the respondents are also in the range of neutral to slightly . The value of THI for both of campus environment is in the range of moderate or neutral.Housing development, well-planned or not well-planned, has changed urban view and its thermal environment.

Pemanfataan Data Equatorial Atmosphere Radar (Ear) Dalam Mengkaji Terjadinya Monsun Di Kawasan Barat Indonesia(the Valuable of Equatorial Atmosphere Radar (Ear) Data to Study Monsoon in the West Area Indonesia)

Kototabang, Padang Panjang and Sicincin city are area in the West part of Indonesia and they are relative in the equator line. Otherwise, three of these cities have difference of behaviors of rainfall for Monsoon. In this study, we were used EAR Data, which were including the rainfall Kototabang, Padangpanjang, and Sicincin. Base on this data (i.e EAR data) in Kototabang, there is monsoon in 8-18 km layer and the higher monsoon is in 14 km layer during the April 2002-April 2006 period. Analisis Power Spectral Density (PSD) and Transformasi wavelet were shown that Monsoon oscillation around 12 months. While vertical profile was presented that the stronger monsoon will be in the wet weather on January. The domination of wind in Kototabang city is South Wind, it is because the wind took water vapor mass from South to North. According to analysis of rainfall in Kototabang, Padangpanjang and Sicincin City, meridional wind in the the Sicincin has rainfall pattern the same as with monsoon. Its was indicated that there were local indicator which can cause the monsoon. From the cross correlation between meridionial wind speed with rainfall in Kototabang, Pontianak and Sicincin, they were shown that three of these cities have significant correlation

Model Kecelakaan Sepeda Motor Pada Ruas Jalan Dengan Menggunakan Pendekatan Glm

In this study, traffic accidents occurred on roads in Batu, East Java, were observed. Based on these traffic accident data, a model was built to relate the number of motorcycle accidents with the availability of road shoulders, traffic flow, and traffic speed. The results indicate that the availability of road shoulders potentially reduce the number of motorcycle accidents. Conversely, increasing the speed and traffic flow potentially increase the number of motorcycle traffic accidents on the roads in Batu

Variasi Spasial Dan Temporal Hujan Konvektif Di Pulau Jawa Berdasarkan Citra Satelit(spatial and Temporal Variation of Convective Rain in Java Island Based on Citra Images)

Convective rain is one of precipitation types that usually occur in Indonesia, result by convective process. This convective rain brings heavy rainfall in short period and could reach a higher intensity than common monsoon rain. Convective process may have a variation with time and location. This research have determined spatial and temporal variation of convective rain in Java island by using the black body temperature (TBB) gradient method based on the GMS-6 (MTSAT-1R) images. As a result, the seasonal convective rain generally occurred in similar period i.e. in the morning from 07.00 to 11.00 LT (local time) and in the evening from 18.00 LT until 05.00 LT. The maximum event occurred from 18.00 LT until mid night. There were different locations between the seasonal convective event. In the seasonal convective rain, there were two spatial patterns. In wet season (DJF) and transitional season from wet to dry (MAM) convective rain spread from east to west Java. While in dry season (JJA) and transitional season from dry to wet (SON), convective rain mostly occurred only in west Java
