ANALISIS KETAHANAN TANAMAN-SAYURAN PADA PARUH PERTUMBUHAN AWAL TERHADAP NaCl : SEBAGAI SARAN BUDIDAYA DI LAHAN-PASANG-SURUT-TIPE-B/C

Salah satu cekaman abiotik pada usaha tani sayuran di lahan pasang surut tipe-B/C adalah cekaman salinitas dikarenakan Na-dd dan kejenuhan basa yang relatif tinggi.  Lahan tipe-B/C merupakan lahan tipe B yang beralih menjadi tipe-B/C.  Penelitian ini bertujuan untuk menganalisa toleransi dan ketahanan beberapa jenis tanaman sayuran terhadap cekaman NaCl pada paruh pertumbuhan awalnya.  Pelaksanaan di Laboratorium Botani dan Fisiologi Tanaman Fakultas Pertanian Universitas IBA di Palembang, pada Oktober-Desember 2020.  Rancangan percobaan RALF 2x5 dengan 3 ulangan, sehingga ada 30 satuan percobaan.  Faktor pertama jenis tanaman sayuran (S) yaitu S1 = sawi caisim (Brassica chinensis L.) var. Tosakan dan  S2 = kailan (Brassica oleracea L.) var. Nova.  Faktor kedua konsentrasi garam NaCl (G) : G0 = 0 ppm (air), G1 = 2.500 ppm, G2 = 5.000 ppm, G3 = 7.500 ppm dan G4 = 10.000 ppm.  Hasil penelitian menunjukkan terjadi penurunan kecepatan tumbuh, keserempakan tumbuh-3 hsp, indeks vigor, tinggi tanaman, panjang akar, jumlah daun, panjang epikotil, dan panjang hipokotil pada konsentrasi 5.000, 7.500 dan 10.000 ppm.  Namun secara keseluruhan,  potensi tumbuh maksimum, daya berkecambah dan keserempakan tumbuh-6 hsp benih pada semua konsentrasi NaCl mencapai 100%.   Tanaman sayuran sawi caisim dapat disarankan sebagai bahan tanam pada budidaya sayuran di lahan pasang surut tipe B/C dikarenakan mempunyai toleransi yang lebih baik terhadap cekaman NaCl dibandingkan kaila

COMMUNITY EMPOWERMENT ON UTILIZATIONHUSK WASTE INTO HUSK CHARCOAL BRIQUETTES

The land characteristics of Pemulutan Ilir Village are dominated by swamps, so the people's main agriculture is the cultivation of lowland swamp rice. The existence of extensive rice fields encourages the development of rice milling businesses that produce husk waste.  The husk waste has not been utilized by the community. If processed, rice husk waste will become a more useful product, once is husk charcoal briquettes. This community service activity is the implementation of the Community Partnership Program of the Ministry of Education and Culture of the Republic of Indonesia in 2022 which is carried out by the IBA University team. The participants are the community of Pemulutan Ilir Village. Activities start from May-December 2022.  Activities are carried out in several stages, starting with surveys and field observations to inventory and analyze partner resources and problems, determine problem solutions, conduct training and mentoring partners to utilize husk waste into charcoal biobriquettes. To the community, there has been a transfer of technological innovation for making husk charcoal briquettes, training and assistance in the process of burning to produce husk charcoal, making adhesive dough, briquette dough and printing briquettes. The result is the peoples of Pemulutan Ilir Village have succeeded in absorbing and being able to carry out all stages for making husk charcoal briquettes and have succeeded in making husk charcoal briquettes that are dense, neat and uniform. The community is very motivated to produce husk charcoal briquettes commercially in order to increase their income and improve the family's econom

Studi Komparasi Fase Vegetatif Tanaman Utama Varietas Padi Berpotensi Ratun Tinggi di Lahan Pasang Surut

Rice ratoon system is one solution constraints of tidal rice fields, particularly the season and limitations of agricultural inputs. The ratoon’s quality highly dependent on the quality of main crop’s vegetative phase. The main crop with maximum vegetative phase, is predicted to produce high growth of ratoon. This study is the second phase of the three experimental stages of multi-year research of hibah bersaing. The first phase of the experiment (September 2013-May 2014) aims to give the height of singgang’s cutting to increase vigor vegetative and reproductive phase of ratoon in tidal land. This experiment is to obtain adaptive rice varieties with high potentially of ratoon in tidal rice fields. This experiment used a randomized block design factors, namely rice varieties (Sintanur, Margasari, Mekongga and Batanghari), with three replications, ongoing since March 2014-September 2014, located in experimental farm of Faculty of Agriculture, IBA University, in Palembang. Each treatment consists of 18 units of plant, so totaly contained 216 experimental units. Rice plants grown in soil media of tidal rice fields that brought from Telang Sari village, Tanjung Lago district, Banyu Asin regency, South Sumatera. The vegetative parameters consist plant height, panicle height, number of tillers, number of productive tillers, chlorophyl, flag leaf area and leaf area. The results indicate that the vegetative phase of Sintanur is the best, measured by plant height and panicle being, number of tillers and productive tillers highest, and flag leaf area and the largest leaf area. This experimental results imply that the quality of growth and vigor of Sintanur’s ratoon would be better than Margasari, Mekongga and Batanghari

The Adaptation of Ciherang Rice Variety Roots to Various Levels of Low Nutrient Stress in Tidal Swamp Soils

Rice cultivation in tidal land has many abiotic stresses. One of them is low nutrient stress. This research aims to determine and study the adaptation of rice roots to various levels of low nutrient stress in tidal swamp soil. These research was carried out from September 2016 to May 2017 at the Experimental Garden, Laboratory of Botany and Plant Physiology of Faculty of Agriculture of IBA University in Palembang, South Sumatra Province. These experiment used a Randomized Block Design with three replications and four low nutrient levels. The treatments are: N1 = 40% Fertilization dose (FD, N2 = 50% FD, N3 = 60% FD and N4 = 100% FD. The 100% FD is 300 kg urea. ha-1, 100 kg SP-36.ha-1 and 150 kg KCl.ha-1. These research used Ciherang rice varieties that planted in pots containing 12 kg of tidal swamp soil type B from Bunga Karang Village, Tanjung Lago District, Banyuasin Regency, South Sumatra Province, Indonesia. The results showed that low nutrient stress increased root length, root weight, root length density, root weight density, root weight ratio and number of tillers, but reduced crown weight and panicle weight per clum
