Abstract

This study aims to determine the effect of fertilizing nutrients that can increase the growth and yield of cucumber (Cucumis sativus L.) with hydroponic techniques. The research was conducted at the screen house of the Biotechnology Lab Research and Development Division of PT East West Seed Indonesia, in Benteng Village, Campaka District, Purwakarta Regency. This research was conducted in December 2017 until March 2018. This study used a randomized block design (RBD) with 9 replications. Planting factor is a nutrient solution consisting of N1 enza nutrition, N2 alfesindo nutrition, and N3 ewindo nutrition. Parameters observed were plant height, plant dry weight, fruit length, fruit diameter, number of planted fruit and crop fruit weight. The media used in this study was roasted husk charcoal. The results showed that the response of nutrient solutions was significantly different from observations of plant height, whereas the response of nutrient solutions to observations of dry weight, fruit length, fruit diameter, number of fruit plantations and fruit weight of plantations were not significantly different. The results showed that the best nutritional solution was ewindo nutritional solution.

Abstract

Produktivitas ternak dilahan kering sepenuhnya bergantung pada ketersediaan pakan dan musim menjadi salah satu penentu ketersediaan pakan. Kelompok Wanita Tani (KWT) Mawar Desa Kuaken TTU-NTT turut merasakan kondisi yang sama. Kegiatan peternakan yang dilakukan oleh KWT adalah penggemukan sapi dan pembibitan sapi serta mendapat bantuan perguliran dari pemerintah setempat. Masalah utamanya adalah ketersediaan pakan yang sangat terbatas sehingga sebagian anggota kelompok melepas ternak berkeliaran, sebagian harus berjalan berkilo-kilometer bahkan memanjat pohon yang tinggi untuk mencari pakan. Untuk itu diperlukan teknologi pengolahan pakan seperti silase. Silase adalah teknik pengawetan pakan pada suasana anaerob pada tempat yang disebut silo. Tujuan dari kegiatan program kemitraan masyarakat di KWT Mawar adalah melatih mitra untuk terampil dalam meningkatkan produktivitas ternaknya melalui penyediaan pakan yang berkualitas sepanjang musim. Metode pelaksanaan yang digunakan adalah participatory action research, dimana KWT dan tim pelaksana secara bersama-sama ikut terlibat dalam kegiatan pelatihan pembuatan silase komplit dan dibantu oleh mahasiswa. Umumnya silase komplit dibuat seperti silase bahan tunggal lainnya perbedaannya terletak pada penggunaan bahan dan aditif yang lebih komplit. Silase komplit yang dihasilkanpun tergolong berkualitas seperti warna hijau alami/hijau kekuningan, beraroma asam, bertekstur padat dan tidak menghasilkan jamur. Kandungan nutrisi silase komplit tergolong berkualitas dengan kandungan bahan kering 43,08%, bahan organik 80,15%/BK, protein kasar 13,33%/BK, lemak kasar 7,12%/BK, serat kasar 12,50%/BK, BETN 45,35%/BK dan EM 3.112, 81 Kkal/BK dengan palatabilitas ternak yang dikategorikan tinggi. Disimpulkan bahwa silase komplit yang dilakukan oleh tim pengabdian dan KWT Mawar dapat berlangsung dengan baik dan menghasilkan silase komplit.

Abstract

Corn (Zea mays L.) is one of the agricultural products whose seeds are used for food. Therefore, a good storage method is needed in order to increase the percentage of seed quality. Storage is one of a series of activities carried out after harvest which aims to reduce or reduce seed moisture content and can also increase the vigor resistance and viability of seeds to the environment. There are two types of storage methods, namely traditional storage methods and modern storage methods. The modern storage method is a development of the traditional development method, only the tools and materials used are different. the lowest percentage germination rate of the six parameters observed was the traditional storage method in jerry cans. This means that the percentage of seed germination rates from the four methods with increased germination rate (>) is in accordance with the observed data even though the seed storage period is at the same time, namely from May to September.

Abstract

Research aimed at knowing the influence of biochar and compost tea level with different levels to increase the growth and yield of peanut plants in Entisol dry land. This research was conducted on 13 July 2019 in experimental Land of the Faculty of Agriculture University of Timor, village of Sasi, Kefamenanu-Timor Tengah Utara, East Nusa Tenggara. Research using the 3 x 3 factorial randomized block design (RBD) with three repeated. The first factor is doses Biochar which is based on 3 (three) levels: without Biochar 0 t/ha, Biochar 5 t/ha, Biochar 10 t/ha. The second factor is the Compost tea Level which is based on 3 (three) levels: no compost tea, 50 mL of Compost tea, 150 mL of Compost tea. Each was repeated 3 times so that there were 27 units of experiments. Interaction of Administration without biochar and compost tea level 150 ml/plant affects the ground temperature 21 HST While the combination treatment of biochar 10 t/ha and compost tea level 150 ml/plant interact positively (P < 0.005) in influencing the number of cropping pods and weight of one hundred seeds. Combination of 10 t/ha biochar and compost tea level 150 ml/plant is the best treatment and average does not give noticeable effect on each treatment level.

Abstract

The composition of the growing media and the frequency of watering can be used as a way to increase the productivity of pakcoy plants. A study was conducted to determine the effect of planting media composition and frequency of watering on the growth and yield of pakcoy (Brassica Rapa L.) on entisol soil in the greenhouse of the Faculty of Agriculture, the University of Timor in April to August 2021 using a factorial completely randomized design consisting of two factors which were repeated 4 times. The first factor consisted of 3 levels, namely soil without biochar compost (K0), 50% biochar compost + 50% entisol soil, (K1), and 75% biochar compost + 25% entisol soil (K2). The second factor consisted of 3 levels, namely the frequency of routine watering in the morning and evening (F0), the frequency of watering every 2 days in the morning and evening (F1), watering every 4 days in the morning and evening (F2). The results showed that the treatment of planting media and the frequency of watering had a significant effect on each parameter and positively interacted with the parameters of the degree of soil acidity. Treatment of planting media dose of 50% biochar compost + 50% entisol soil was the best treatment in increasing the growth and yield of pakcoy plants. The frequency of watering for 4 days in the morning and afternoon was the best treatment in increasing the growth and yield of pakcoy plants.

Abstract

Introduction: This study aimed to determine the growth of pakcoy at the time of fertigation and the composition of the verticulture system planting media with different spacing of planting holes and their interactions on dry land. Methods: The method used is an experiment using a Split Plot Design using 3 plots. The main plot is the spacing of the planting holes consisting of 15 cm, 20 cm, and 25 cm. The subplot is the composition of the growing media consisting of soil:sand, soil:biochar; sand:biochar; and soil:sand:biochar. The sub-sub plot is fertigation time which consists of 60 seconds, 90 seconds, and 120 seconds. A total of 36 treatments were repeated 2 times for a total of 72 treatments. Results: Results: The results of this study showed that the interaction of fertigation time significantly affected the growth of plant height, number of leaves and fresh weight of crown with the best combination treatment of 120 seconds of fertigation time with soil:biochar growing media. Fertigation time has a significant effect on all observation parameters, with the best treatment being fertigation for 120 seconds. The composition of the growing media had a significant effect on the observations of plant height, the number of leaves, and the fresh weight of the crown with the best results found in soil: biochar growing media (1:1). Conclusion: The best combination result is a fermentation time of 120 seconds and the composition of soil and biochar (W3M2).
