Oil palm plantations are a potential commodity of Riau Province and the highest contributor to palm oil production in Indonesia. The development of agricultural science and technology, which is disseminated through various media, is a source of information for farmers. However, the availability of information sources does not guarantee that farmers will benefit from the information. This is influenced by media literacy from these farmers. This research aimed at analyzing the media’s literacy of oil palm farmers. The research was conducted in three districts with potential oil palm at Riau Province. They are Pelalawan District, Rokan Hilir District and Rokan Hulu District. The respondents of oil palm farmers were 185 farmers, which were selected by stratified random sampling. This research applied Likert Summated Rating Scale (LSRS) method. The results of this research are: The literacy level of oil palm farmers is in the medium level (average score of 1.72), while for three aspects which are technical skill and critical understanding are in the medium level and communication skill is basic level. Role of government and related parties are needed to help improve the literacy level of oil palm farmers. This is necessary so that the farmers together with extension workers, will be ready to face the challenge of the development of science and technology in the oil palm industry, by utilizing the development of information and communication technologies such as smartphones.
<p>Abstrak: Selama era Reformasi, sistem pendidikan nasional sedang menghadapi sejumlah problem. Dalam aspek tujuan pendidikan nasional, misalnya, lembaga- lembaga pendidikan tampak belum bisa mencapai tujuan pendidikan nasional secara utuh. Pembentukan akhlak mulia dalam diri anak sebagai salah satu bagian dari tujuan pendidikan nasional masih menjadi persoalan. Banyak faktor penyebab problem ini, antara lain adalah kurangnya peran orangtua dan guru dalam membentuk akhlak anak sejak usia dini. Tulisan ini akan menyajikan pandangan Ibn Miskawaih tentang urgensi pembentukan akhlak anak sejak usia dini. Kajian ini menemukan bahwa seorang anak akan mampu menampilkan akhlak mulia manakala pendidik, baik orangtua maupun guru, mampu memahami kejiwaan anak sembari mulai mengajari dan membiasakan anak dengan akhlak mulia sejak kecil, serta memilih lingkungan yang sehat secara moral untuk anak tersebut.</p><p><br />Abstract: Early Childhood Character Building in the View of Ibn Miska- waih. During the reformation era, the national education system is apparently facing some problems. On the goal of national education, for instance, educational institutions have not achieved their goals in the true sense. The noble character building in the child as part of the national education objective has yet become problem. There are a number of factors that led to these problems, some of which are the minor role of the parents and teachers in building child’s character since early childhood. This writing cast some lights on the importance of child character building since early childhood in Ibn Miskawaih’s view. This study finds that a child will be able to be acquainted with noble character when educators, whether parents or teachers, are capable of understanding the child’s psychological state and begin teaching to live with it since childhood. Also contributed to the character building success is choosing healthy environment morally for the child.</p><p><br />Kata Kunci: akhlak, anak usia dini, Ibn Miskawaih</p>
Provinsi Riau memiliki potensi besar pada sektor perkebunan. Dua komoditi yang menjadi andalan adalah kelapa sawit dan keret, dengan pelaku utama dan paling banyak adalah petani swadaya. Salah satu kemampuan petani yang diperlukan saat ini dengan memanfaatkan perkembangan teknologi informasi dan komunikasi adalah kemampuan literasi media. Literasi media merupakan kemampuan petani memanfaatkan teknologi informasi untuk mencari atau mengakses melalui internet, memahami, memanfaatkan informasi dalam usahatani dan mengkomunikasikan informasi tersebut. Tujuan penelitian ini adalah menganalisis tingkat literasi petani pekebun di Provinisi Riau. Penelitian dilakukan di empat kabupaten di Provinisi Riau, dengan jumlah petani responden 240 orang petani. Hasil penelitian menunjukkan bahwa tingkat literasi petani berada pada level basic (skor 2,61), yang dikaji dari tiga aspek yaitu (1) aspek technical skill dengan skor 1,64 pada kategori basic; (2) Aspek critical understanding dengan skor 1,66 masuk pada kategori medium; dan (3) Aspek communication abilities pada kategori basic dengan skor 1,54. Hal ini menggambarkan bahwa masih rendahnya kemampuan petani baik petani kelapa sawit maupun karet dalam memanfaatkan teknologi informasi dan komunikasi seperti handphone (HP) atau smartphone yang mereka miliki untuk kebutuhan usahataninya. Peran penyuluh sangat diperlukan untuk meningkatkan litersi media petani pekebun, sehingga petani dapat memanfaatkan teknologi informasi dan komunikasi dalam mengembangkan usahataninya.
Urban farming adalah salah satu solusi sistem pertanian di kota, karena saat ini terjadi penyempitan lahan kosong akibat pembangunan di perkotaan. Tujuan utama kegiatan pertanian perkotaan adalah untuk menjaga ketahanan pangan keluarga. Kegiatan urban farming dilakukan dalam dua bentuk kegiatan yaitu warung hidup dan budikdamber (budidaya ikan dan tanaman dalam ember). Penerapan dilakukan melalui sosialisasi budikdamber yang terdiri dari ikan lele dan tanaman kangkung serta melalui kegiatan pembuatan warung hidup dengan memanfaatkan perkarangan rumah warga dan yang lebih difokuskan pada tanaman-tanaman yang sering dikonsumsi oleh keluarga dan mudah untuk dibuat dalam bercocok tanam. Masyarakat sangat antusias dalam mengikuti kegiatan ini, dan telah menerapkan membudidayakan sayuran di pekarangan dan membuat budikdamber
