Abstract

Pengembangan singkong Jarak Towo meningkatkan ketersediaan bahan baku olahan pangan dan pendapatan petani. Hal ini karena keunggulan rasa dan tekstur halus dengan harga mencapai 3 sampai 4 kali lipat dari varietas lain. Sebagai bahan baku industri pengolahan pangan, harus didukung dengan kandungan gizi yang berkualitas. Penelitian ini bertujuan untuk mengetahui produktivitas, parameter pertumbuhan, kandungan gizi singkong Jarak Towo dengan perlakuan dosis pupuk P dan K serta ketinggian tempat yang berbeda. Penelitian ini menggunakan percobaan rancangan acak kelompok lengkap dengan faktorial kombinasi dosis pupuk P dan K. Dosis pupuk P tiga level berupa SP36 yaitu 0 kg ha-1, 100 kg ha-1, dan 200 kg ha-1, sedangkan dosis pupuk K berupa KCl tiga level yaitu 0 kg ha-1, 150 kg ha-1, 300 kg ha-1 sehingga diperoleh sembilan kombinasi perlakuan yang diulang di tiga lokasi yaitu Desa Kemuning, Sepanjang, dan Wonorejo pada ketinggian 700 mdpl, 927 mdpl, and 1034 mdpl. Hasil penelitian menunjukkan bahwa singkong Jarak Towo yang dibudidayakan di Desa Kemuning memiliki kadar air dan lemak tertinggi 54,28 ± 2,76% dan 0,78 ± 0,21%. Kandungan karbohidrat dan protein tertinggi diperoleh di Desa Wonorejo 15,74 ± 4,25% dan 2,42 ± 0,23%. Perlakuan pupuk P dan K tidak berpengaruh signifikan terhadap parameter pertumbuhan, produktivitas dan nutrisi dalam singkong Jarak Towo.ABSTRACTThe development of Jarak Towo cassava increases the availability of processed food raw materials and farmers' income. This is because of the superiority of taste and smooth texture with prices reaching 3 to 4 times that of other varieties. As a raw material for the food processing industry, it must be supported by quality nutritional content. This study aimed to determine productivity, the growth parameters, nutritional content of Jarak Towo cassava with different doses of P and K fertilizers and altitudes. This research used a completely randomized block design trial with a factorial combination of P and K fertilizer doses. The dose of P fertilizer at three levels in the form of SP36 was 0 kg ha-1, 100 kg ha-1, and 200kg ha-1, while the dose of K fertilizer in the form of KCl 3 levels was 0 kg ha-1, 150 kg ha-1, 300 kg ha-1 in order to obtain nine treatment combinations repeated in three locations, namely Kemuning, Sepanjang, and Wonorejo Villages at an altitude of 700 masl, 927 masl, and 1034 masl. The results showed that Jarak Towo cassava cultivated in Kemuning Village had the highest water content and fat content of 54.28 ± 2.76% and 0.78 ± 0.21%. The highest carbohydrate and protein content were obtained in Wonorejo Village 15.74 ± 4.25% and 2.42 ± 0.23%. The treatment of P and K fertilizers had no significant effect on the growth parameters, productivity and nutrition in Jarak Towo cassava.

Abstract

Padi merupakan komoditas pangan yang memiliki peranan terpenting dalam memenuhi kebutuhan pokok masyarakat Indonesia. Ekstensifikasi produksi padi dapat dilakukan dengan memanfaatkan lahan marjinal seperti lahan salin. Lahan salin merupakan lahan yang memiliki kadar kadar garam tinggi akibat intrusi air laut maupun tingginya laju evaporasi. Pengembangan budidaya padi di lahan salin memiliki kendala berupa serangan patogen busuk pelepah (Rhizoctonia solani). Alternatif pengendalian patogen selain menggunakan pestsida kimia, dapat dilakukan menggunakan Plant Growth Promoting Rhizobacteria (PGPR), seperti kelompok bakteri diazotrof. Penelitian ini bertujuan untuk mengetahui potensi bakteri diazotrof lahan salin dalam meningkatkan ketahanan tanaman padi serta kemampuannya dalam memacu pertumbuhan padi yang terinfeksi R. solani. Penelitian dilaksanakan di Experimental Farm dan Laboratorium Agronomi & Hortikultura, Fakultas Pertanian Unsoed pada bulan Oktober 2021 - Februari 2022. Rancangan yang digunakan adalah Rancangan Acak Kelompok Lengkap (RAKL) dengan 11 perlakuan dan diulang tiga kali, meliputi kontrol tanpa inokulasi bakteri diazotrof dan inokulasi isolat Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn dan K3. Semua tanaman juga dinokulasi dengan Rhizoctonia solani. Hasil penelitian menunjukkan bahwa inokulasi bakteri diazotrof dapat meningkatkan ketahanan padi yang terinfeksi jamur R. solani, ditandai dengan penurunan intensitas penyakit hingga 70%, peningkatan kandungan saponin, tanin dan hidrokuinon, serta peningkatkan pertumbuhan tinggi tanaman dan panjang akar total padi.ABSTRACTRice is the most important  food commodity that supply the basic needs of the Indonesian people. The development of rice cultivation in salin land has obstacles in the form of attacks by sheat blight pathogen (Rhizoctonia solani). Alternative to controlling pathogens other than using chemical pesticides is by using Plant Growth Promoting Rhizobacteria (PGPR), such as diazotroph bacteria. This research aimed to determine the potential of diazotrof bacteria in increasing rice resistance and its ability to stimulate the growth of rice infected with R. solani. The research was carried out at Experimental Farm and Agrohorti Laboratory, Faculty of Agriculture Unsoed in October 2021 - February 2022. The design used was Randomized Completely Block Design (RCBD) with 11 treatments and repeated three times, including controls without inoculation of diazotroph bacteria and inoculation of isolates Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn and K3. All plants were also inoculated with R. solani. The results showed that inoculation with diazotrof bacteria could increase the rice resistance towards attack of sheath blight pathogen (R. solani) that characterized by a decrease disease intensity up to 70%, increase saponins, tannins and hydroquinones content, also increase growth of plant height and total root length of rice.
