Abstract

Abstrak. Nematoda parasit adalah hama dan penyakit yang dapat berdampak pada penurunan kuantitas dan kualitas tanaman.Kalimantan Timur telah mengendalikan nematoda parasit, tetapi tidak menjadi perhatian konselor pertanian dan petani hanyamenggunakan pestisida umum yang dapat mempengaruhi pengendalian nematoda parasit. Penelitian ini didasarkan pada deskriptifdan eksploratif untuk mengetahui keberadaan jamur nematoda pada pupuk kandang. Eksplorasi jamur nematoda menggunakan medialarutan pupuk kandang yang telah diencerkan 10-3 dan telah ditambahkan oleh ± 50 jamur nematoda. Hasil penelitian ini ditemukansembilan genera jamur. Delapan genus jamur dipastikan sebagai nematofag dan satu jamur (Circinella sp) belum diperoleh. Jamursebagai nematofag adalah Dactylella sp .; Arthrobotrys sp .; Gliocladium sp .; Trichoderma sp .; Verticillium sp .; Sarocladium sp.;Aspergillus sp. dan Monacrosporium sp.

Abstract

Penelitian ini dilakukan untuk mengetahui status keragaman nematoda pada lahan reklamasi pasca tambang batubara dan hutan sekunder (pembanding). Penelitian ini dilakukan di Fakultas Pertanian Universitas Mulawarman selama 4(empat) bulan. Pengambilan sampel tanah dilaksanakan di Desa Bangun Rejo Kecamatan Tenggarong Seberang, Kalimantan Timur. Dilanjutkan dengan ekstraksi nematoda menggunakan metode Baermann yang dimodifikasi, dan identifikasi nematoda yang didapatkan sampai tingkat genus berdasarkan ciri morfologinya. Pengamatan nematoda dilakukan di laboratorium Ilmu Hama Penyakit Tumbuhan Fakultas Pertanian Universitas Mulawarman Samarinda. Hasil penelitian menunjukkan bahwa ditemukan 14 genera nematoda, terdiri dari 6 genera nematoda non-paasit dan 8 genera parasit tumbuhan. Genus nematoda yang dominan secara berturut-turut adalah sebagai berikut: Apelenchus, Cephalobus, Dorylaimus, Pratylenchus, dan Rhabditis. Kepadatan populasi nematoda berkisar 30-206 individu 100 gram-1 tanah. Keanekaragaman nematoda pada lahan reklamasi tergolong sedang dengan indeks Shannon-Wienner berkisar 1,22-3,09, sedangkan pada lahan pembanding (hutan sekunder) tergolong tinggi dengan indeks Shannon-Wienner berkisar 3,06 – 3,49. Kata kunci : Lahan Reklamasi Pasca Tambang Batu bara, Keragaman Nematoda, Indikator Biologi.

Abstract

Penyakit blas merupakan salah satu penyakit utama pada tanaman padi yang mampu menimbulkan kerugian besar bagi para petani sehingga petani mengendalikan penyakit ini dengan menggunakan bahan kimia yang merusak lingkungan dan menimbulkan dampak negatif lain. Melihat pentingnya pengendalian penyakit ini maka dibutuhkan alternatif pengendalian dengan menggunakan agens pengendali hayati. Percobaan dilakukan di Kelurahan Sungai Kapih, Kecamatan Sambutan, Kota Samarinda, dari Desember 2020 hingga April 2021. Hasil percobaan disusun dalam Rancangan Acak Kelompok (RAK) faktorial, yang terdiri dari tiga varietas, dengan lima perlakuan dan diulang sebanyak lima kali. Hasil penelitian menunjukkan bahwa varietas Ciherang merupakan varietas yang paling rentan dibandingkan varietas Kambang dan Pandan Ungu. Cendawan endofit yang diaplikasikan terhadap tanaman memberikan pengaruh yang baik untuk pengendalian penyakit Blas dan juga meningkatkan ketahanan tanaman, dalam hal ini cendawan yang memberikan efektivitas terbaik yaitu cendawan Trichoderma sp. yang mampu menekan intensitas serangan penyakit blas lebih dari 85% sehingga dapat digunakan sebagai alternatif pengendalian yang ramah lingkungan.

Abstract

Endemic leaf rust disease always occurs in almost all maize plantations in Indonesia. Furthermore, the development of this disease differs concurrently and is greatly influenced by the ecological conditions of maize cultivation. Therefore, this study fills the epidemiological gap of diseases that has not been conducted against the epidemiology of maize rust. This identifies the causes of leaf rust that attacked the maize plants in two locations, namely Bayur and Muang Dalam, Lempake, Samarinda, Indonesia. This study also analyzed the relationship or model between ecological factors of temperature, humidity, and soil fertility on the intensity of leaf rust and the infection rate of maize leaf rust. Measurement of disease intensity, the rate at which it developed, soil fertility and temperature and humidity of the area are conducted in this study. Meanwhile, soil fertility also influenced disease progression and the nutrient-poor soils in two sites cause leaf rust disease to develop well. The identification results showed that the cause of maize leaf rust was Puccinia sorghi Schw. Therefore, the temperature accompanied by the increased humidity is directly proportional to the development of the leaf rust.

Abstract

Water hyacinth weeds can cause disturbances in the form of silting and increase competition with other plants. On the other hand, water hyacinth has purple flowers, very beautiful when it blooms quite a lot, it can be used as an ornamental plant that refreshes the view and adds aesthetic value. This study aimed to assess the potential of water hyacinth (Monochorea vaginalis) as an ornamental plant and to see the response of water hyacinth to the application of Gandasil D. This study was designed in a t-test that was not given Gandasil D (P0) fertilizer and was given Gandasil D (P) fertilizer. Assessing the potential of rice water as an ornamental plant, a questionnaire was conducted on 20 respondents. Parameters observed for fertilization response were plant height, number of leaves, number of seeds and number of flowers. Data were analyzed using a t-test comparison at the 5% level. The results showed that the color of the rice water flower has a beauty value and has an aesthetic value, so this plant has the potential as an ornamental plant, and it is necessary to protect the rice water plant against plant pest organisms. The application of fertilizer to water hyacinth (Monochoria vaginalis) had no effect on plant height, number of leaves, number of seeds and number of flowers.

Abstract

This research was a solution to free desease banana kepok yellow which was decrease the banana product in East Kalimantan. This research were devided three years and it would be continued. The first years seedling propagation free desease through tissue culture. The second years the seedling derived tissue culture which was planted on the field, until harvesting fruit product. The third years processing fruit product to several kind of industrial product. The aim of the first years research was the highest number shoot regenerated from the explant center of banana corm, which induction several combination treatment of plant growth regulator Benzyl Amino Purine (BAP) and Indole Butyric Acid (IBA). This research conducted at Tissue Culture Laboratory of Agriculture Faculty of Mulawarman University, from March until November 2015. This research was used Randomized Completely Block Design with two factors. The firest factor : BAP consist 3 level consentration were : 2,5; 5 and 10 ppm and the secon factor : IBA consist 3 level consentration were : 0; 1 and 2 ppm. So that all of combination of plant growth  regulator were 9 treatments. Each treatments were replicated ten times. Result of this research showed that all combination of concentration treatment of plant growth regulator BAP and IBA could be induce the growth and differentiation of explant center of banana corm in Murashige and Skoog (MS) media, like : inbibition, developed tissue of explant, callusing and shooting, although the percentage and totality was variation. The colour of callus was yellow and light green. While the structure was hard and compact. The highest average number of shoots induction at VII combination treatments BAP 10 ppm + IBA 0 ppm ware 3.80± 1,76 shoots/explant which was the root un completely development. So that it need sub culture to the rooting induction media with IBA 10 ppm to be formed completely plantlet (seedling), which could be survived on acclimatization processing.
