Abstract

Sunflower (Helianthus annus L.) is one of the ornamental plant which is economically. It is potential because of oil contains and has the beautiful flower. Induced mutation is important to get genetic diversity of Sunflower. Mutations are genetic changes in either a single cell or a number of genes or chromosomal changes that can cause somaclonal variations. This research was aimed to find the LD20 and LD50 and to identify genetic diversity of Sunflower with the dosage 0, 150, 200, 250 and 300 Gy. The results showed that the higher LD20 and LD50 was at 158.338 gy and 260.339 gy. The gamma ray iradiation was induce variation and affected significantly toward quantitative character of plant height. Key words: diversity, induced mutation, iradiation, LD20, LD50

Abstract

Brassica juncea is one of vegetable consumed by many people. One of the ways to expand genetic diversity is by inducing the occurrence of mutations. Mutations can be induced by offering chemical mutagens as well as physical mutagens. One of chemical have been successful to induce mutation is colchicine. The aim of this research was to determine effect of colchicine on Brassica growth. This research was conducted in June 2019 in the Experimental Field, Labuhanbatu University. The result show that soaking brassica seeds using colchicine make a decrease in the average plant height, leaf widht and number of leaves compare to control cause abnormal cell division. Keywords: Brassica juncea, Colchicine, Growth response

Abstract

Legume cover crop (Mucuna bracteata L.) is a creeper which is currently often used to increase soil fertility in plantation areas. This plant is a leguminous plant that can fix nitrogen nutrients in the soil. One of the M.bracteata plant breeding programs to increase diversity is mutation using gamma ray radiation. The research objective was to determine the level of radiosensitivity of legume cover crop using gamma ray irradiation. The research was conducted at PAIR BATAN using a Gamma Chamber 4000A irradiator and in agricultural experiment, Labuhanbatu University. The plant material used was M.bracteata seeds with irradiation doses of 0, 200, 250, 300, 350 and 400 Gy. This study uses a curve fit analysis program to calculate the LD50 value (Lethal dose 50). The results showed that the plant radiosensitivity by calculating the LD50 value of M.bracteata at the age of 2 Weeks After Planting) was 348.737 Gy. The higher the radiation dose given, the lower the percentage of growth. Keywords: diversity; leguminous; lethal dosage; mutation; gamma rays

Abstract

Chrysanthemum (Chrysanthemum indicum L.) is an ornamental plant that is included in an important contribution in the ornamental plant business. Related to chrysanthemum buds grown in vitro in culture tubes or bottles with a tightly closed to avoid bacterial and fungal contamination and to protect the humidity of the culture environment. However, this tight cap often affects the composition of the gas in a jar or bottle, which inhibits plant growth. The purpose of this study was to study the effect of photoautotrophic on the growth of chrysanthemum buds in the in vitro culture process and the differences in invitro and exvitro chrysanthemum stomata. This research was conducted in March 2016 to May 2016 in the Microtechnical Laboratory, IPB University. Research results obtained from research on the position given to research conducted on the number of roots, the number of books and the number of shoots. The influence of the environment of exvitro also significantly affects the number of stomata, stomata width and stomata density. Keywords :ex vitro,  in vitro, photoautotrophic

Abstract

Perbaikan kualitas lahan merupakan salah satu teknologi yang penting untuk meningkatkan hasil panen dan pendapatan petani serta bisa digunakan secara berkelanjutan. Penggunaan pupuk organik cair dari limbah pertanian merupakan alternatif yang dapat dijadikan sebagai sumber nutrisi bagi tanaman. Pengabdian ini bertujuan untuk meningkatkan pengetahuan terhadap petani mengenali pentingnya penggunaan bahan organik sebagai amelioran tanah untuk memperbaiki kesuburan tanah dan meningkatkan kemampuan tanah dalam menyerap serta mentransportasikan hara ke tubuh tanaman sehingga menghasilkan panen yang lebih baik dan berkelanjutan. Dari sosialisasi yang dilakukan petani Lestari di Kelurahan Bakaran Batu Kecamatan Rantau Selatan, sebagian besar petani melakukan budidaya hortikultura dan tanaman palawija. Namun, memiliki keterbatasan dalam pengolahan lahan karena memberikan bahan organik segar dari kotoran ayam yang bersifat panas sehingga mengganggu pertumbuhan tanaman dan tanaman cabai yang dibudidaya relatif sedikit. Selanjutnya, permasalahan petani ditemukan pada masa bera tanah yang relatif singkat tanpa pemberian bahan organik sehingga tanah di lahan petani menjadi lebih keras, berwarna cerah dan bersifat masam. Pengabdian di kelompok tani Lestari memberikan solusi berupa pembagian pupuk organik cair dan memberikan pemaparan cara mengolah limbah kotoran ayam menjadi kompos dengan cara inkubasi, masa pengolahan tanah dan pemberian bahan organik pada saat pengolahan. Tindak lanjut dari pengabdian ini direncanakan kerjasama antar petani, penyuluh dan perguruan tinggi untuk melakukan pecobaan demplot di lapangan menggunakan bahan organik dari yang dibuat oleh petani pada saat sosialisasi tahap awal.

Abstract

Pengolahan minyak kelapa sawit menghendaki mutu yang baik secara kualitatif maupun kuantitatif. Proses pengolahan yang kurang cermat mengakibatkan efek samping yang tidak diinginkan seperti menurunkan mutu minyak. PT.HSJ yang berlokasi di Desa Sidomulyo, Kecamatan Bilah Hilir, Kabupaten Labuhan Batu, Provinsi Sumatera Utara merupakan anak perusahaan dari PT. Asian Agri yang bergerak di sektor pengolahan minyak kelapa sawit. Penelitian ini bertujuan untuk mengetahui mutu minyak kelapa sawit mentah di perkebunan PT. Hari Sawit Jaya. Sampel diambil dari keran pipa ex vacuum drier CPO dalam 2 hari yang berbeda. Adapun dalam satu hari pengambilan, sampel diambil sebanyak 5 sampel setiap 2 jam sekali. Parameter penelitian ini adalah kadar asam lemak bebas, kadar air dan zat pengotor. Hasil Penelitian CPO di PT. HSJ telah memenuhi standar yang ditetapkan oleh PT.HSJ dan SNI. Rata-rata kadar asam lemak bebas, kadar air dan kadar zat pengotor pada pengambilan sampel hari pertama adalah 3,06%, 0,20%, 0,022% dan hari kedua dengan rata-rata 3,17%, 0,19%, 0,022%.

Abstract

Most of Kampung Padang resident is a farmer especially as a oil palm and rubber farmer. In the cultivation of oil palm and rubber, there are still a few villagers from Kampung Padang who plant Mucuna between plants as a ground cover crop or Legume Cover Crop, even though Mucuna has many benefits, especially for suppressing weed growth and improving soil chemical properties. The difficulty of obtaining seeds makes people rarely use Mucuna. Some techniques that can be done to induce flowering in plants are using a growth regulator (ZPT) paclobutrazol. Several research results regarding the use of paclobutrazol have succeeded in shortening the length of plant tendrils. Other techniques that can be used to induce flowering in plants are providing water stress, ringing the plants, and pruning the roots of the plants. The response from the people of the Padang village population was very enthusiastic, seen from the many people who asked questions during the event.
