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

Hidroponik NFT (Nutrient Film Technique) merupakan salah satu sistem hidroponik dimana lapisannutrisi yang sangat dangkal disirkulasikan melewati akar tanaman. Sistem hidroponik bergantung pada nutrisianorganik sebagai pemasok unsur hara. Penggunaan pupuk hayati diharapkan dapat mengurangi dosis pupukanorganik yang diaplikasikan pada sistem hidroponik agar lebih efisien. Penelitian ini bertujuan untukmengetahui dosis terbaik kombinasi pupuk hayati dan pupuk anorganik dalam meningkatkan populasi bakteriendofit, kandungan klorofil dan hasil tanaman pakcoy pada hidroponik sistem NFT. Penelitian telahdilaksanakan diLaboratorium Biologi Tanah, Fakultas Pertanian Universitas Padjadjaran, Jatinangor,Sumedang.Percobaan ini menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari empat perlakuanyaitu 100% Pupuk Anorganikdan 100% Pupuk Hayati + Pupuk Anorganik 100%, 75% dan 50%. Variabel yangdiamati adalah tinggi tanaman, populasi bakteri endofit, kandungan klorofil, hasil tanaman. Hasil penelitianmenunjukkan bahwa pemberian 100% pupuk hayati dan 50% pupuk anorganik dapat mengurangi penggunaanpupuk anorganik hingga 50 % dan berpengaruh terhadap peningkatan populasi bakteri endofit, kandunganklorofil dan hasil tanaman pakcoy pada hidroponik sistem NFT.Kata kunci: bakteri endofit, klorofil, pupuk hayati, hidroponik NFT, pakcoyABSTRACTHydroponics NFT (Nutrient Film Technique) is one of the hydroponic systems where superficial layers ofnutrients are circulated through plant roots. Hydroponic system is depended on anorganic nutrient as nutrientssupplier. The use of biofertilizer was expected to reduce the dosage of inorganic nutrient solution on hydroponicsystem. The aims of this research were to find the best dosage combination biofertilizer and inorganic nutrientsolution on the population of endophytic bacteria, chlorophyll content and yield of pakcoy (Brassica rapa L) onhydroponic NFT system. The research has been conducted at Soil Biology Laboratory of Faculty of AgriculturePadjadjaran University, Jatinangor, Sumedang Regency. The design experiment was randomized blockdesignwhich consisted offour combinationthat was 100% inorganic nutrients and 100% biofertilizer + inorganicnutrients 100%, 75% and 50%. The variables observed were plant height, population of endophytic bacteria,chlorophyll content, plant yields. The results showed that 100% biofertilizer and 50% anorganic nutrition canreduce usage inorganic nutrients up to 50% and take effect on population of endophytic bacteria, chlorophyllcontent and yield of pakcoy (Brassica rapa L) on hydroponic NFT system.Keywords: endophytic bacteria, chlorophyll, biofertilizer, NFT hydroponic, pakcoy
