Abstract

ABSTRACT Petai is a plant that belongs to the MPTS (Multi Purpose Tree Species) plant type which can be used multiple times for both wood and non-wood. Petai also has benefits from an economic perspective (fruit and wood) and ecology (legume plants fertilize the soil) so it needs to be cultivated well. There are several factors that influence the quality of cultivation results, one of which is the planting media. The planting medium used is soil in the sub-soil layer as an alternative to top soil. However, this layer is not as fertile as the top soil layer, so it is necessary to add soil improving materials (Ameliorants), for example organic materials. This research aims to analyze the effect of adding various organic materials to sub-soil planting media on the growth of Petai seedlings and to obtain the best organic material composition to add to sub-soil planting media which can have a real influence on the growth of Petai seedlings. This research was carried out for 3 months using a completely randomized design (CRD) method with 1 factor, namely planting media (M) consisting of 5 treatments, namely m1 (Sub soil + compost 3:1), m2 (Sub soil + husk charcoal 2:1), m3 (Sub soil + Cocopeat 2:1), m4 (Sub soil + Boiler ash 4:1) and m5 (Sub soil + Laying chicken manure + Sand 1:2:1). The best organic material composition to add to the sub soil planting medium is cocopeat (2:1). Keywords: petai, planting media, organic materials. ABSTRAK Petai merupakan tumbuhan yang tergolong dalam jenis tanaman MPTS (Multi Purpose Tree Species) yang dapat dimanfaatkan secara ganda baik kayu maupun non kayunya. Petai juga memiliki manfaat dari segi ekonomi (buah dan kayunya) maupun ekologi (tumbuhan legum menyuburkan tanah) sehingga perlu dibudidayakan dengan baik. Ada beberapa faktor yang mempengaruhi kualitas hasil budidaya salah satunya media tanam. Media tanam yang digunakan adalah tanah pada lapisan sub soil sebagai alternatif pengganti tanah top soil. Namun, lapisan ini tidak sesubur lapisan top soil sehingga diperlukan penambahan bahan pembenah tanah (Amelioran) contohnya bahan organik. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan berbagai bahan organik pada media tanam sub soil terhadap pertumbuhan bibit petai serta untuk mendapatkan komposisi bahan organik terbaik untuk ditambahkan ke media tanam sub soil yang dapat memberikan pegaruh nyata dalam pertumbuhan bibit Petai. Penelitian ini dilaksanakan selama 3 bulan dengan menggunakan metode rancangan acak lengkap (RAL) 1 faktor yaitu media tanam (M) yang terdiri dari 5 perlakuan yaitu m1 (Sub soil + kompos 3:1), m2 (Sub soil + arang sekam 2:1), m3 (Sub soil + Cocopeat 2:1 ), m4 (Sub soil + Abu boiler 4:1 ) dan m5 (Sub soil + Pupuk kandang ayam petelur + Pasir 1:2:1). Komposisi bahan organik terbaik untuk ditambahkan ke dalam media tanam sub soil adalah cocopeat (2:1). Katakunci: petai, media tanam, bahan organik.

Abstract

ABSTRACT Sunlight plays a crucial role in the process of photosynthesis because it provides the energy source that plants need. The intensity of light received by plants greatly affects their growth and the efficiency of photosynthesis. The rate of photosynthesis in plants is also greatly influenced by the intensity of sunlight, where if there is sufficient light intensity, adequate amounts of water and carbon dioxide, and appropriate temperatures, photosynthesis will usually reach its peak. The purpose of this research is to observe the rate of photosynthesis in Tanjung (Mimusops elengi Linn.) and Merbau darat (Intsia palembanica) plants with various treatments such as the addition of topsoil, subsoil, rice husk charcoal, cocopeat, sand, cow dung fertilizer, and NPK fertilizer using a plant photosynthesis meter. The research was conducted at the Educational Forest and Nursery Laboratory of the Forestry Department, Faculty of Agiculture, Jambi University. The results of this study indicate that Tanjung with the treatment of topsoil, rice husk charcoal, and 5 g of NPK is the best fertilizer application, as evidenced by the highest photosynthesis rate of 31.7 µmolCO2 m-2s-1. Meanwhile, for the merbau darat seedlings, the treatment with topsoil, sand, and 2 g of NPK fertilizer yielded the highest results for the photosynthesis rate.   Keywords: photosynthesis rate, NPK fertilizer, merbau darat, tanjung, subsoil   ABSTRACT Cahaya matahari sangat berperan dalam proses fotosintesis karena dapat memberikan sumber energi yang sangat dibutuhkan oleh tanaman. Intensitas cahaya yang diterima tanaman sangat mempengaruhi pertumbuhan dan efisiensi fotosintesis. Laju fotosintesis pada tanaman juga sangat di pengaruhi oleh intensitas cahaya matahari, dimana jika intensitas cahaya yang cukup, jumlah air dan karbon dioksida yang cukup serta suhu yang sesuai, fotosintesis biasanya akan mencapai puncaknya. Tujuan dari penelitian ini adalah untuk melihat seberapa tinggi laju fotosintesis pada tanaman Tanjung (Mimusops elengi Linn.) dan Merbau darat (Intsia palembanica) dengan berbagai perlakuan seperti penambahan media topsoil, subsoil, arang sekam, cocopeat, pasir, pupuk kotoran sapi dan pupuk NPK dengan alat plant photosyntesis meter. Penelitian dilakukan di Laboratorium Hutan Pendidikan dan Pembibitan Jurusan Kehutanan, Fakultas Pertanian Universitas Jambi. Hasil penelitian ini menunjukan bahwa tanaman Tanjung dengan pemberian perlakuan topsoil, arang sekam dan NPK 5 g merupakan pemberian pupuk terbaik dengan hasil laju fotosintesis tertinggi yaitu 31,7 µmolCO2m-2s-1. Sedangkan pada bibit merbau darat dengan pemberian perlakuan topsoil, pasir dan pupuk NPK 2 g mendapatlan hasil tertinggi untuk laju fotosintesisnya.   Kata kunci: laju fotosintesis, merbau darat, pupuk NPK, tanjung, subsoil

Abstract

ABSTRACT Red caliandra (Calliandra calothyrsus Meissn) is a plant that belongs to the Fabaceae family. Callindra has a rapid growth rate, reaching a height of 3-5 meters in the first year on suitable land. The planting medium commonly used for seedlings includes ultisol soil, which generally has sensitive aeration pores and low stability index, causing the soil to easily become compacted. The growth of quality calliandra seedlings in the nursery is influenced by soil fertility; therefore, additional treatment in the form of fertilizer is necessary to ensure sufficient nutrient content. One of the fertilizers that can be used is the NPK compound fertilizer. This fertilizer is one of the inorganic fertilizers that is very efficient in increasing the availability of macro nutrients N, P, and K. This research was conducted in the Forest Cultivation Laboratory of the Faculty of Agriculture, Jambi University, using the Completely Randomized Design (CRD) method with one factor, namely the NPK fertilizer 15:15:15. The treatments given were: P0 (without treatment), P1 (NPK 1 grams), P2 (NPK 2 grams), P3 (NPK 3 grams), P4 (NPK 4 grams), and P5 (NPK 5 grams). Observation parameters include height increase, diameter, leaf count, root dry weight, and shoot dry weight. Based on the research results, it can be concluded that the application of NPK fertilizer has no significant effect on the growth of calliandra seedlings in ultisol media, as observed in all parameters. The application of NPK at certain doses does not yield optimal results in the growth of callindra seedlings.   Keywords: NPK, red calliandra, ultisol ABSTRAK Kaliandra merah (Calliandra calothyrsus Meissn) merupakan tanaman yang termasuk ke dalam famili fabaceae. Kaliandra merah memiliki pertumbuhan yang cepat, ditahun pertama tingginya dapat mencapai 3-5m pada lahan yang memadai. Media tanam bibit yang banyak digunakan diantaranya adalah tanah ultisol yang umumnya peka memiliki pori aerasi dan indeks stabilitas rendah sehingga menyebabkan tanah mudah menjadi padat. Pertumbuhan bibit kaliandra yang berkualitas di persemaian dipengaruhi oleh kesuburan tanah, dengan demikian perlu perlakuan tambahan berupa pupuk agar unsur hara mencukupi. Salah satu pupuk yang dapat digunakan adalah pupuk majemuk NPK. Pupuk ini merupakan salah satu pupuk anorganik yang sangat efisien dalam meningkatkan ketersediaan unsur hara makro N, P, dan K. Penelitian ini dilaksanakan di Laboratorium Budidaya Hutan Fakultas Pertanian Universitas Jambi dengan menggunakan metode Rancangan Acak Lengkap (RAL) 1 faktor yaitu pupuk NPK 15:15:15. Perlakuan yang diberikan yaitu: P0 (tanpa perlakuan), P1 (NPK 1 gram), P2 (NPK 2 gram), P3 (NPK 3 gram), P4 (NPK 4 gram), dan P5 (NPK 5 gram). Parameter pengamatan berupa pertambahan tinggi, diameter, jumlah daun, berat kering akar, dan berat kering tajuk. Berdasarkan hasil penelitan, dapat disimpulkan bahwa pemberian pupuk NPK berpengaruh tidak nyata terhadap pertumbuhan bibit kaliandra merah pada media ultisol yang terlihat pada semua parameter. Pemberian NPK dengan dosis tertentu tidak memberikan hasil optimal pada pertumbuhan bibit kaliandra merah.   Kata kunci: NPK, kaliandra merah, ultisol

Abstract

Eucalyptus pellita is a type of fast-growing plant (fast-growing species). The advantage of this plant is that it is a short rotation or fast-growing plant, with fewer disease attacks. The benefits of the plant are quite numerous and it has high economic value. Considering that the optimal light intensity for eucalyptus seedling growth is not yet known, it is necessary to test the effects of various light intensities using shade in the form of paranet. This research was conducted using a factorial Completely Randomized Design (CRD) with a split-plot experimental pattern consisting of 4 treatment levels. Each treatment was repeated 3 times, The results of the study on the effect of NPK fertilizer and light intensity on the growth of eucalyptus seedlings indicate that the interaction of 5g NPK fertilizer per seedling and 100% light intensity is a better treatment compared to other treatments. This is suspected because eucalyptus is a plant that requires sufficient light intensity to experience the growth of eucalyptus seedlings. The growth of eucalyptus seedlings is influenced by light intensity, which supports the increase in height, stem diameter, and number of leaves. Based on the results of this study, it can be concluded that the treatment with NPK fertilizer and light intensity has a significant effect on increasing stem diameter. In the treatment P2C0, which is NPK fertilizer 7g/seedling and light intensity 100%, there is no significant difference compared to treatments P1C0 and P3C0, which are NPK fertilizers 5g and 9g/seedling at 100% light intensity.

Abstract

Calliandra (Calliandra sp.) is a shrub with multiple benefits, including its use as firewood and as a high-protein livestock feed. Sengon (Paraserianthes falcataria) is a fast-growing tree species widely cultivated to support the timber industry. To enhance seedling growth and productivity, environmental manipulation through shading and fertilization is necessary. This study aims to evaluate the effects of shading and NPK fertilizer doses on the growth of Calliandra calothyrsus and Sengon seedlings in the context of industrial forest plantation management. Using a completely randomized design, this study tested four shading levels (no shading, 25%, 50%, and 75%) and four NPK fertilizer doses (0, 1, 2, and 3 g per seedling). Each treatment was repeated twice, resulting in a total of 248 seedlings per species. The observed variables included height, diameter, and leaf count. The results showed that Calliandra exhibited no significant differences in height growth across shading levels. However, the best growth was observed under 25% shading, with a height increase of 11.84 cm and a diameter of 1.55 mm, and at an NPK dose of 2 g, with a height of 10.75 cm and a diameter of 1.54 mm. Meanwhile, Sengon showed the best height growth under 75% shading with an NPK dose of 1 g per seedling. The optimal diameter growth for Calliandra was achieved under 25% shading with an NPK dose of 1 g, while Sengon exhibited the best diameter growth without shading and with an NPK dose of 3 g.
