Abstract

Pembangunan sistem pertanian terpadu telah dilakukan di salah satu lahan pekarangan warga Desa Sei Semayang Kecamatan Sunggal Kabupaten Deli Serdang Sumatera Utara. Di lahan seluas ± 1022 m2 terdapat pohon hutan berupa kombinasi mahoni, dan jati (berumur 11 tahun), serta trembesi, damar, jelutung dan ketapang (berumur 3 tahun), di lahan selanya dipelihara ternak kambing, ikan (kolam tanah untuk ikan lele, nila, patin, dan gurami), unggas (itik dan ayam), serta sebagian lahan ditanami tanaman pertanian (sayuran terong, cabai, rimbang, ubi kayu, dan lain-lain) dengan sistem surjan dan pot yang secara intensif dilakukan sejak Januari 2012 hingga kini. Dari pohon hutan telah dipanen 3 batang pohon mahoni untuk pembuatan kusen pintu dan jendela. Dari kolam telah dipanen ikan lele dumbo dan dari 10 ekor ternak kambing telah berkembang menjadi 14 ekor dalam 1 tahun. Dari 15 ekor induk itik dan ayam dapat dipanen rata-rata 5 butir telur per hari. Dengan demikian, sistem ini telah memberi manfaat tambahan kesejahteraan ekonomi keluarga dan perbaikan ekologi (kesejukan dan peningkatan biodiversitas) di lahan pekarangan. Pengelola sistem pertanian terpadu ini adalah Komunitas Pemuda Peduli Lingkungan (KOPPLING) Pondok Miri Desa Sei Semayang.

Abstract

Paradigma baru pertanian terpadu harus memberdayakan segenap multi-fungsi pertanian terpadu sebagai pemasok utama sandang, pangan, dan papan bagi kehidupan seluruh makluk hidup; juga sebagai gatra lingkungan hidup yang berkelanjutan, penyedia keindahan lingkungan (wisata-agro), penghasil bio-farmaka dan penghasil bio-energi.Gerakan “Jihad Kedaulatan Pangan” (JKP) dalam menumbuh kembangkan kecintaan dalam memproduksi sendiri dan menggunakan produk pangan unggulan lokal secara sungguh-sungguh, tanpa bergantung pada pangan impor lagi. Gerakan ini harus didukung secara sinergi, utuh, terpadu dann yata oleh seluruh pemangku kepentingan agar membentuk jaringan antar ABCG (Academic / akademisi, Business / pedagang swasta, Community / masyarakat, Government / pemerintah) yang erat dan nyata. Kedaulatan Pangan dapat digapai dengan mengaplikasikan konsep Pertanian Terpadu melalui strategi 5A (Agro-produksi, Agri-bisnis, Agro-industry, Agro-teknologi, Agro-wisata) yang memberdayakan seluruh potensi sumber daya alam, air, hayati, lingkungan, SDM dan manajemen secara menyeluruh, terpadu, utuh dan saling sinergis.Konsep ini harus terpadu dari hulu ke hilir untuk masing-masing komoditas unggulan utama sehingga mempunyai nilai tambah di bidang ekonomi, pelestarian lingkungan, sosial dan budaya secara sinergis.Indonesia mempunyai kemampuan, kemauan dan kesempatan untuk mencapai Kedaulatan Pangan, namun komitmen politik dan ekonomi harus dirorong lagi. Dengan perbaikan peraturan, kepemimpinan, pelaksanaan, SDM, teknologi, sinergisme, dan manajemen di seluruh lini 5A ini, maka diharapkan dapat memperbaiki kelemahan utama komoditas pertanian agar mampu memenuhi standart 3K (kuantitas, kualitas dan kontinyuitas) serta bersertifikat halalal thoyiban.Peran pers dan edu-tainment sangat penting untuk meningkatkan image building, kepercayaan, komitmen dan peran nyata seluruh stake holder untuk mendukung program unggulan mendukung Jihad Kedaulatan Pangan.

Abstract

Pemanfaatan lahan pekarangan termasuk di Kota Padang relatif masih terbatas, sehingga pengembangan berbagai inovasi yang terkait dengan lahan pekarangan belum banyak berkembang. Untuk menentukan profil pertanian lahan pekarangan ditinjau dari aspek budidaya di Kota Padang maka selama bulan Januari 2013 telah dilakukan studi Pemahaman Pedesaan dalam Waktu Singkat (Rapid Rural Appraisal/RRA). Hasil studi menunjukan bahwa ibu rumah tangga yang melaksanakan usahatani lahan pekarangan terdiri dari berbagai golongan umur dan tingkat pendidikan. Di wilayah berpenduduk cukup padat latar belakang pekerjaan mereka adalah PNS, pegawai swasta dan buruh sedangkan di wilayah berpenduduk agak jarang adalah petani. Lahan pekarangan di wilayah berpenduduk cukup padat berkisar dari 20 m2 (sangat sempit) hingga 100 m2 (sedang). Selanjutnya pada wilayah berpenduduk agak jarang > 170 m2 (luas). Komoditas pertanian yang banyak dijumpai pada wilayah berpenduduk cukup padat antara lain: Cabe Merah, Cabe Rawit, Saledri, Keladi, Mangga, Jeruk Nipis, Jambu, Pepaya, Kunyit, Pandan, Ruku-ruku, dan ayam buras. Sedangkan di wilayah berpenduduk agak jarang dijumpai komoditas, seperti Ubi Kayu, Ubi Jalar, Talas, Rimbang, Cabe Merah, Cabe Rawit, Keladi, Mangga, Jeruk, Jambu Biji, Pepaya, Pisang, Kunyit, Sereh, Ruku-ruku, Kelapa, Pinang, Kakao dan ayam buras. Budidaya pada lahan pekarangan umumnya masih dilakukan secara tradisional sehingga hasilnya belum optimal.

Abstract

Evaluation of agricultural programs is necessary to determine the level of success of an agriculturalprogram. The objective is to evaluate the research in the integrated farming program implemented infive villages in the District of Pulau Sebuku and to create a better and sustainable alternative model ofthe integrated farming application. The evaluation uses a multicriteria analysis method to make thecriteria and indicators of integrated farming principles. It can be concluded that not all of thecriteria can be accepted. Out of 10 criteria, one criterion namely environmental goals can beaccepted (with score ≥ 3) in the five villages. Two criteria namely the economic purpose and landmanagement can be accepted in four villages. The next two criteria namely social objectives andmarketing support can be accepted in two villages. Two other criteria, namely waste managementand climate/weather management can only be accepted by one village. Three criteria have notbeen acceptable to all villages, namely crop management, cattle management, and institutionalmanagement. The analysis indicates a lack of institutional function, knowledge, and technology inintegrated farming among community. Efforts to improve the program by establishing agriculturalinstitutions, human resource development as well as ease of access to saprodi and marketingfacilities. The involvement of all parties including the community, the government, the private sectorand NGOs is needed to achieve the expected success of integrated farming.

Abstract

The objective of this research was to obtain a genotype of selected putative mutant withgood agronomic traits and high yielding on the optimum condition and its adaptability todrought stress in M3 generation. The study result showed that there were differences in thegrowth and production of each population as a result of irradiation in optimum conditions anddrought stress conditions. The population as a result of irradiation at 150 Gy and 200 Gy had a highermean value for the plant height trait, the number of productive branches, the number of productivenodes and the number of productive pods compared to irradiation population of 50 Gy, 100 Gy andthe control population of Argomulyo at optimum conditions. The decrease in the growth anddevelopment happened to all the characters observed in the irradiation population in droughtconditions compared to when grown in optimum conditions. The decrease can be seen in thecharacters of plant height, the number of pods and seed weight per plant. The growth and developmentof the population irradiation of 150 Gy and 200 Gy were more influenced by drought conditionscompared to other irradiation populations. The selection in the optimum conditions produced 291high yielding genotypes and the selection in drought conditions generated 202 genotypes andadapted to drought environments.
