Abstract

PT.Pertani bergerak salah satunya di bidang produksi dan distribusi benih. Berdasarkan benih yangdipasarkannya, ada dua jenis konsumen benih padi PT. Pertani yaitu konsumen benih bersubsidi dan non subsidi.Penelitian ini dilakukan untuk menentukan kualitas bauran pemasaran benih padi bersertifikat non subsidiberdasarkan kepuasan petani padi sebagai konsumen benih. Penelitian dilakukan dengan teknik deskriptifkuantitatif yang mengidentifikasi tingkat kesesuaian antara kepentingan dan pelaksanaan bauran pemasaran yangdirasakan oleh petani padi, prioritas perbaikan bauran pemasaran, serta tingkat kepuasan petani. Terdapat tujuhatribut bauran pemasaran yang dinilai berdasarkan prinsip bauran pemasaran 7P dan dianalisis dengan metodeImportance-Performance Analysis (IPA) dan Customer Satisfaction Index (CSI). Penelitian dilakukan di empatdesa yang berada di wilayah Kios Tani Ramah, Kabupaten Karawang. Alasan pemilihan Kios Tani Ramah adalahkarena kios ini adalah pemasar benih padi bersertifikat terbesar dari PT. Pertani Cabang Karawang, dimana PT.Pertani sendiri merupakan satu dari dua BUMN yang memproduksi benih padi bersertifikat. Variabel yang akanditeliti pada penelitian ini adalah bauran pemasaran 7P (Product, Price, Place, Promotion, People, Process, danPhysical Evidence). Hasil penelitian menunjukkan bahwa yang menjadi prioritas untuk ditingkatkan ialah atributketahanan hama, penyakit, kesesuaian harga dengan kualitas, promosi word of mouth, dan kebersihan kios. Tingkatkepuasan petani berdasarkan penilaian CSI yaitu 75,20% atau 0,752 yang berarti ada pada kriteria puas, karenaberada diantara 0,66 – 0,80.Kata kunci: kepuasan petani, bauran pemasaran, benih padi bersertifikat, non subsidi, IPAABSTRACTOne of PT.Pertani’s business branch is seed production and distribution. Based on the seeds market, thereare two types of consumers of PT. Pertani. Those are, subsidized and non-subsidized seed consumers. Thisresearch was conducted to determine the quality of marketing mix of certified rice seeds based on the satisfactionof the rice farmers as seed consumers. The research was conducted with quantitative descriptive analysis methodthat identifies the level of conformity between the importance and the implementation of the marketing mixperceived by the rice farmers, the priority of the marketing mix improvement, and the level of farmer satisfaction.There are seven marketing mix attributes that are judged by the 7P marketing mix principle and analyzed byImportance-Performace Analysis (IPA) and Customer Satisfaction Index (CSI) method. The study was conductedin four villages located in Kios Tani Ramah area, Karawang Regency. The reason for choosing Tani Ramah Kioskis because this kiosk is the largest certified rice seeds marketer from PT. Pertani Karawang Branch, where PT.Pertani itself is one of two state-owned enterprises that produce certified rice seeds. The variables to be sold inthis study are 7P marketing mix (Product, Price, Place, Promotion, People, Process, dan Physical Evidence). Theresults showed that the priorities to be improved are the attribute of pest resistance, disease, price conformity withthe quality, word of mouth promotion, and the kiosk's hygiene. The level of farmer satisfaction based on the CSIassessment is 75.20% or 0.752 which means it is within the "satisfied" criteria, because it is between 0.66 - 0.80.Keywords: farmer satisfaction, marketing mix, certified rice seed, non subsidized, IPA

Abstract

Salah satu faktor penentu keberhasilan budidaya pertanian di lahan rawa pasang surut adalah waktu tanam.Waktu tanam tanaman pangan terutama padi mempunyai peranan yang sangat penting pada produksi akhir hasilpertanian. Di Indonesia saat ini dikenal 3 Musim Tanam, yaitu musim hujan, antara bulan November-Pebruari,musim kemarau I, antara bulan Maret-Juni; dan musim kemarau II, antara bulan Juli-Oktober. Akan tetapi,dinamika perubahan iklim seperti kekeringan (El Nino) dan kebasahan (La Nina) yang tidak menentu, berimbaspada pergeseran awal dan akhir musim tanam serta berdampak negatif bagi produktivitas tanaman padi. Adanyahal tersebut, analisis tentang waktu tanam padi di lahan rawa pasang surut Pulau Kalimantan perlu dilakukan.Waktu tanam di lahan pasang surut dimulai setelah jumlah air hujan mencukupi untuk melarutkan kadar besi yangada di dalam air. Realisasi tanam di Provinsi Kalimantan Barat umumnya terjadi pada Dasarian 28 (Oktober),Kalimantan Timur pada Dasarian 31 (November), serta Kalimantan Selatan dan Kalimantan Tengah pada Dasarian7 (Maret). Waktu tanam di lahan rawa pasang surut menunjukkan tingkat kekukuhan yang tinggi terhadapperubahan iklim, dimana waktu tanam tidak terlalu berubah selama 10 tahun pada kondisi iklim yang berbeda.Kata kunci: dasarian, luapan, air hujan, kekukuhanABSTRACTOne of the critical factors for agricultural cultivation in tidal swamp land is cropping time. Paddy croppingtime has a very important role in the final production of agricultural cultivation. Currently, there are 3 croppingtime in Indonesia, in the rainy season (November to February), first of dry season (March to June), and second ofdry season, (July to October). However, the climate change dynamic such as drought (El Nino) and wetness (LaNina), shifting the cropping time and resulting a negative impact on the productivity of paddy rice. Therefore, ananalysis of the rice cropping time needs to be done on Kalimantan tidal swampland area. Cropping time in thetidal swampland area began after the amount of rain was sufficient to dissolve the levels of iron in water. In WestKalimantan, the cropping time realization generally occurs in Dasarian 28 (October), while East Kalimantan onDasarian 31 (November), and South Kalimantan and Central Kalimantan on Dasarian 7 (March). Cropping timein tidal swamp land showed a high level of resistance to climate change, in which planting time did not changefor 10 years in different climatic conditions.Key words: decadal, tidal, rainwater, substantiality

Abstract

Padi di Kabupaten Jember mengalami penurunan produksi, salah satunya disebabkan oleh organismepengganggu tanaman. Aplikasi PHT (Pengendalian Hama Terpadu) dengan memanfaatkan musuh alami dapatditerapkan agar ekosistem pertanaman padi seimbang. Penggunaan refugia bagi hama padi diharapkan efektifuntuk mengurangi populasi dan serangan hama. Penelitian dilakukan dari Agustus hingga Oktober 2017 di DesaSuren, Kecamatan Ledokombo, Kabupaten Jember. Refugia yang digunakan adalah kenikir (Cosmos caudatus)dan bunga kertas (Zinnia elegans). Pengambilan sampel acak adalah sistematis (pola zig-zag). Variabel yangdiamati adalah investasi dan klasifikasi populasi serangga. Prosedur pengumpulan data menggunakan metodepengumpulan data primer. Populasi hama padi tertinggi diketahui pada perlakuan yang tidak berada pada tanamanrefugia di pinggir sawah dan hama yang paling dominan adalah wereng hijau poppy atau Nipothetix spp denganjumlah populasi rata-rata 12 ekor. Pengamatan tanaman padi yang diolah dan ditanami tanaman refugia di pinggirsawah, diketahui populasi tertinggi pada umur 4 MST dan serangga yang diidentifikasi adalah hama. Total musuhalami pada tanaman padi tanpa tanaman refugia sebanyak 305 ekor, tanaman padi dengan tanaman refugiasebanyak 438 ekor. Populasi serangga musuh alami lebih besar pada tanaman padi dengan tanaman refugia. Halini disebabkan sepanjang sawah ditumbuhi gulma dan tanaman refugia.Kata kunci: Cosmos caudatus, Nipothetix spp, Zinnia elegansABSTRACTRice is the staple food commodity of Indonesian society.
