Abstract

This research was carried out in smallholder oil palm plantations in Tebing Tinggi Village, Mara Sebo District, Batanghari Regency from March to June 2021. The purpose of the study was to observe the diseases that exist in oil palm plantations, the percentage and intensity of the disease attacks. This study used a survey method with random sampling at 3 locations of smallholder plantations in Tebing Tinggi village, namely 20 sample plants from each garden. Observe all plants and count how many are symptomatic of the disease. Then calculated the percentage and intensity of disease attacks. Samples of diseased plants were taken and wrapped in damp newspapers for identification at the Unbari Basic Laboratory. The results showed that in Tebing Tinggi village, Mara Sebo Ulu district, the highest percentage of Curvularia leaf spot disease caused by the fungus Curvularia sp was found in P2 area at 40%, Drechslera leaf spot disease attack caused by Drechslera sp fungus was highest in P2 land. by 35%, and the highest attack of crown disease (Crown Disease) caused by the fungus Fusarium sp. was found in P3 land by 20%. The intensity of disease attacks found in Tebing Tinggi Village, namely, the intensity of the attack of Curvularia Leaf Spot disease caused by the fungus Curvularia sp in Tebing Tinggi village was 28.75%, the intensity of Drecshlera Leaf Spot disease caused by Drechslera sp fungus was 26.25% and Crown disease crown disease is 6.6%.

Abstract

Benih kakao tergolong benih rekalsitran dengan kadar air tinggi dan peka terhadap penurunan kadar air. Daya tumbuh cepat menurun sampai benih tersebut mati dalam penyimpanan. Penurunan kadar air di bawah titik kritis merupakan masalah,  benih mudah berkecambah, dan mati bila disimpan pada suhu rendah. Adanya media simpan yang baik diharapkan benih dapat disimpan lebih lama serta mempertahankan daya kecambah dan kekuatan  tumbuh benih. Penelitian bertujuan mendapatkan media yang tepat untuk penyimpanan benih kakao dan secara bersamaan mempertahankan daya kecambah dan kekauatan tumbuhnya. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan satu faktor perlakuan yaitu penggunaan media simpan yang berbeda dengan 4 jenis media yaitu  serbuk gergaji (P1), cocopeat (P2), arang sekam padi (P3), dan serbuk arang kayu (P4), setiap jenis media diulang sebanyak 3 kali sehingga terdapat 12 petak percobaan yang masing- masing berisi 40 benih kakao. Peubah yang diamati adalah : kadar air media simpan, kadar air benih, persentase daya kecambah dalam penyimpanan, persentase benih berjamur, identifikasi jamur, persentase daya kecambah, kecepatan berkecambah, dan panjang kecambah.  Data hasil pengamatan dianalisis dengan uji F dan dilanjutkan uji Duncan pada taraf α 5%. Hasil penelitian menunjukkan bahwa media arang sekam padi dapat mempertahankan kualitas benih kakao dengan indikator benih berjamur selama 12 hari penyimpanan sebesar 0,92%. Setelah 12 hari disimpan, daya kecambah sebesar 64,20%, kecepatan berkecambah  2,1 etmal-1, dan panjang kecambah 6,82 cm. Jamur yang teridentifikasi selama penyimpanan adalah jamur Aspergilus. spp

Abstract

This research was conducted at the Oil Palm Plantation of PT. Inti Indosawit Subur (PT.IIS), Tanjung Benanak, Merlung, Tanjung Jabung Barat from 20 January to 20 March 2021. This study aims to determine the response of oil palm seedling growth to super bionic liquid fertilizer at certain concentrations in the main nursery. This study used a completely randomized design (CRD) with super bionic liquid fertilizer treatment consisting of 5 levels, namely; s0 = control, s1 = 3 cc liter-1 super bionic liquid fertilizer per seedling, s2 = 6 cc liter-1 super bionic liquid fertilizer per seedling, s3 = 9 cc liter-1 super bionic liquid fertilizer per seedling, and s4 = 12 cc liter-1 super bionic liquid fertilizer per seedling. Parameters observed were plant height (cm), stem diameter (cm), shoot dry weight (g), root dry weight (g), and root-shoot ratio at 8 WAP. The research data were analyzed using analysis of variance, if it had a significant effect, then continued with Duncan's Multiple Distance Test (DNMRT) at the 5% level. The results showed that the application of super bionic liquid fertilizer had a significant effect on stem diameter, shoot dry weight, root dry weight and had no significant effect on plant height and root-shoot ratio. The application of super bionic liquid fertilizer with a concentration of 9 cc liter-1 resulted in an increase in plant height of 15.38%, stem diameter 23.78%, shoot dry weight 100%, root dry weight 71.56%, and root-shoot ratio 6.88. % compared to without super bionic liquid fertilizer (control).Keywords ; super bionic liquid fertilizer, palm oil

Abstract

Abstract            This research was conducted at Jl. Lintas Jambi - Muaro Bulian Kel. Pijoan Kec. Jaluko Kab. Muaro Jambi, which lasted for 3 months. This study aims to determine the response of oil palm seedlings (Elaeis guineensis Jacq) of multi embryo origin in the main breeding.             Oil palm seedlings used type Multi Embrio that has been 4.5 months. The medium used is black soil, fertilizer npk brand Lao Ying (16:16:16) and polybag size 5 kg. The design used in this study was Completely Randomized Design (RAL) with the treatment of npk laoying time with 4 treatment levels F1 5 days 2.5 g, F2 10 days 5.0 g, F3 15 days 7.5 g, F4 20 day 10 g. Each treatment was repeated 4 times, so there were 16 units of experimental unit, each plot consisting of 3 oil palm seedlings, bringing the total of 48 polybags. Each plot was taken 2 plants used as sample. The parameters observed were seed height (cm), stem diameter (mm), dry weight of crown (g), root dry weight (g), and quality index (IK).             Based on the research objectives, the results and discussion, it can be concluded that the NPK (16:16:16) with the frequency of different feeding time on oil palm seed planting medium gives no significant effect on plant height and stem diameter but significantly different to the weight dried canopy, root dry weight and seed quality index of multi-embryo palm oil. The F1 treatment also gives the highest index value of quality (IK) indicating that the seedlings are most ready to be transported. Abstrak            Penelitian ini dilaksanakan di Jl. Lintas Jambi – Muaro Bulian Kel. Pijoan Kec. Jaluko Kab. Muaro Jambi, yang berlangsung selama 3 bulan. Penelitian ini bertujuan untuk mengetahui respon bibit kelapa sawit ( Elaeis guineensis Jacq ) asal multi embrio di pembibitan utama.             Bibit kelapa sawit yang digunakan jenis Multi Embrio yang telah berumur 4,5 bulan. Media yang digunakan adalah tanah hitam, pupuk npk merk Lao Ying (16:16:16) dan polybag ukuran 5 kg. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan perlakuan frekuensi waktu pemberian npk lao ying dengan 4 taraf perlakuan F1 5 hari 2,5 g, F2 10 hari 5,0 g, F3 15 hari 7,5 g, F4 20 hari 10 g. Setiap perlakuan diulang 4 kali, sehingga terdapat 16 unit satuan percobaan, yang masing-masing petak terdiri dari 3 bibit kelapa sawit, sehingga jumlah 48 polybag. Setiap petak diambil 2 tanaman yang digunakan sebagai sampel. Parameter yang         diamati adalah tinggi bibit (cm), diameter batang (mm), berat kering tajuk (g), berat kering akar (g), dan indeks kualitas (IK).            Berdasarkan tujuan penelitian, hasil dan pembahasan, maka dapat disimpulkan bahwa pemberian NPK (16:16:16) dengan frekuensi waktu pemberian yang berbeda pada media tanam bibit kelapa sawit memberikan pengaruh yang tidak nyata terhadap tinggi tanaman dan diameter batang, tapi berbeda nyata terhadap berat kering tajuk, berat kering akar dan indeks kualitas bibit kelapa sawit asal multi embrio. Perlakuan F1 juga memberikan nilai indeks kualitas (IK) tertinggi yang mengindikasikan bibit tersebut paling siap dipindahkan kelapangan.
