Abstract

Sukun (Artocarpus altilis Parkinson ex F.A.Zorn) yang ada di Indonesia umumnya adalah tanpa biji. Sehingga sangat sulit untuk dikembangkan secara generatif dengan biji. Alternatifnya adalah dengan perkembangbiakan secara vegetatif dengan setek. Faktor penting untuk menjamin kelangsungan hidup suatu setek adalah pembentukan tunas dan akar yang dapat dirangsang dengan zat pengatur tumbuh (ZPT). Salah satu ZPT alami yang dapat digunakan utuk merangsang pertumbuhan akar dan setek adalah ekstrak bawang merah. Penelitian ini adalah untuk mengetahui lama perendaman ekstrak bawang merah terhadap pertumbuhan akar dan tunas setek batang sukun Pengambilan bahan setek sukun dilakukan di kawasan Desa Madapolo, Kecamatan Obi, Kabupaten Halmahera Selatan, Provinsi Maluku Utara. Perlakuan yang diterapkan adalah perbedaan lama perendaman bahan setek batang sukun ke dalam larutan ekstrak bawang merah. Lama perendaman yang diterapkan sebanyak 4 perlakuan, yaitu: 0 menit (kontrol), 10 menit, 20 menit, dan 30 menit. Pengamatan pertumbuhan tunas setek dilakukan selama 12 minggu dan pengamatan akar dilakukan pada akhir pengamatan. Hasil pengamatan menunjukkan bahwa lama perendaman ZPT alami ekstrak  bawang merah berpengaruh terhadap pertumbuhan tunas dan akar setek. Jumlah tunas terbanyak pada perlakuan tanpa perendaman ekstrak bawang merah, sedangkan panjang tunas yang tertinggi adalah pada perlakuan perendaman ekstrak bawang merah selama 30 menit, demikian pula untuk jumlah dan panjang akar.

Abstract

Kualitas media berpengaruh terhadap terhadap pertumbuhan tanaman karena dalam media tanam terdapat unsur hara yang mendukung pertumbuhan. Komposisi media tanam yang berbeda diduga juga memberikan pengaruh yang berbeda terhadap pertumbuhan. Penelitian ini bertujuan untuk mengidentifikasi respon pertumbuhan bibit jabon merah pada komposisi media tanam yang berbeda. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan perlakuan perbedaan komposisi media tanam (M1:tanah, M2:tanah dan pasir, M3:tanah, pasir dan kompos, dan M4:tanah, pasir dan pupuk kandang). Variabel pertumbuhan bibit yang diamati adalah tinggi bibit, diameter bibit, jumlah dan luas daun. Adapun parameter pertumbuhan bibit yaitu Nisbah Pucuk Akar (NPA) dan Indeks Mutu Bibit (IMB). Hasil penelitian menunjukkan bahwa media M4 memberikan pertumbuhan yang lebih besar pada tinggi bibit, diameter bibit, jumlah dan luas daun. Adapun M3 memberikan nilai NPA dan IMB yang lebih tinggi. Perbedaan komposisi media tanam berpengaruh nyata pada variabel pertumbuhan luas daun. Komposisi media tanam terbaik untuk pertumbuhan bibit jabon merah yang optimal adalah M4 (tanah, pasir, dan pupuk kandang dengan perbandingan 3:2:1).

Abstract

Guludan technique becomes an alternative for mangrove rehabilitation in the disused fishponds. This technique has been implemented since 2005 on the coast of Jakarta. The wider application of this technique requires several studies in advance to see growth of the mangrove in the already planted guludan. This study aims to measure the growth of mangroves planted by guludan techniques, identify environmental factors that affect their mangrove growth, and analyze their relationship. Measurements were performed on 40 guludan samples which planted by Rhizopora mucronata in 2010 - 2013. Rhizopora mucronata grew well in the guludans, followed by Sonneratia caseolaris that grew naturally. Both were dominated by individuals in sapling phase. Meanwhile, environmental factors affecting mangrove growth were N-total, P, Mg, Ca, Na, clay texture, CEC, soil salinity, soil pH, and water level in the guludan.Keywords: guludan technique, mangrove rehabilitation, Rhizophora mucronata, Sonneratia caseolaris

Abstract

Totodoku Village in East Wasilei District is inhabited by people from the Tobelo Dalam Tribe. This community was a tribal community from the forest and still uses medicinal plants from the forest. Unfortunately, knowledge about medicinal plants can change when there is excessive land exploitation or interaction with people from other tribes. Its application will change if it is not passed on to the modern younger generation. This study aims to identify the diversity of medicinal plants and their uses in Totodoku Village. This research was conducted in October - December 2020. Data were collected by surveying medicinal plants in 4 transects and interviewing the community regarding the use of medicinal plants. The data were analyzed to obtain the Important Value Index (IVI) and describe its uses. There were 29 species of medicinal plants from 21 families. The dominant species were kirinyuh (Chromolaena odorata) which is used to treat cysts, diabetes and ulcers; and awar-awar (Ficus septica) as a medicine to strenthen joints and has anti-inflammatory effects. The seedling and sapling phases were dominated by Chromolaena odorata, the IVI values were 41.60% and 55.9%, respectively. The pole phase was dominated by Ficus septica with IVI of 39.08 The species diversity index was in the medium category (H’=2.605), while the species evenness index is fairly evenly distributed (E=0.77). Utilizations of medicinal plants is done by drinking them (26 species) and sticking them on the sick body parts (3 species).

Abstract

Jelutung is a tree species of the family Apocynaceae that is famous for its latex use as material for chewing gum. In Indonesia there are two species, namely jelutung land (Dyera costulata) and jelutung swamp (Dyera polyphylla). Until now, information on the differences in the two types of jelutung morphology is still very limited. There is therefore the need for a study on the variation of both types cultivated. This study was conducted to estimate variations in leaf morphology for land and swamp jelutung to assess 14 variables of its leaf morphology. Results of multivariate analysis (PCA, MCA, and CDA) showed that jelutung can be classified into two groups: D. costulata and D. polyphylla. PCA and MCA showed three variables that most distinguishes the two types of jelutung consecutive leaf length (PL), Roving Leaf (KL) and the shape of apex (AS). The CDA variables that play a major role in the classification of Dyera are the shape of apex (AS), the form of the base of the leaf (BS), leaf vein angle (SD).

Abstract

Sengon is commonly developed by community forest farmers because it is a fast-growing species and the demand for wood is quite high. The development of sengon is constrained by the attack of gall rust disease caused by the fungus Uromycladium falcatarium. Efforts to obtain disease-resistant plants can be done through mutation breeding, one of which is using gamma rays. This study aims to assess the resistance of M1 generation sengon to gall rust disease. Sengon seeds were irradiated using gamma rays at doses of 0, 25, 75, 125, and 175 Gy. Sengon seeds that had been irradiated were germinated and sown for up to 2 months of age. Inoculation of U. falcatarium fungus was carried out on sengon seedlings M1 (1st generation mutant) and M0 (control) generations, at 2 months old. The number of seeds used in each dose was five seeds with four replications. This study used a randomized block design (RBD). Observation on seedlings were disease severity, mortality rate, and resistance of seedlings to gall rust disease. Data were analyzed using analysis of variance (ANOVA) and then analysis of the least significant difference (LSD) was carried out at a level of 5%. The results showed that the dose of gamma irradiation had a significant effect on the severity of gall rust disease at 17, 27, and 37 days after isolation (DAI). The resistance levels of the M0 and M1 generations of sengon seedlings (doses of 25, 75, and 125 Gy) from 7 – 37 DAI were in the very resistant-moderately susceptible category, while the M1 seedlings with a dose of 175 Gy tended to be very resistant-resistant.Keywords: gall rust, gamma irradiation, mutation breeding. AbstrakSengon umum dikembangkan petani hutan rakyat karena termasuk jenis cepat tumbuh dan permintaan kayunya cukup tinggi. Pengembangan sengon terkendala dengan adanya serangan penyakit karat tumor yang disebabkan oleh jamur Uromycladium falcatarium. Upaya untuk memperoleh tanaman yang tahan penyakit dapat dilakukan melalui pemuliaan mutasi, salah satunya dengan sinar gamma. Penelitian ini bertujuan untuk mengaji ketahanan sengon generasi M1 terhadap penyakit karat tumor. Benih sengon diiradiasi menggunakan sinar gamma dengan dosis 0, 25, 75, 125, dan 175 Gy. Benih sengon yang telah diiradiasi dikecambahkan dan dipelihara hingga umur 2 bulan.

Abstract

Khairun University Campus IV is currently being developed as an educational tourism location. One form of activity is developing agricultural land. The problem there is that the land is still not very fertile. Efforts that can be made are by developing ectomycorrhizal inoculants to increase soil fertility. Community service activities are directed at providing training to the community around Campus IV Unkhair in producing ectomycorrhizal inoculants. Ectomycorrhiza has several benefits for plants, namely being able to increase the uptake of P and N nutrients. The series of service activities carried out are providing training and practice in exploring ectomycorrhiza in the forest around the Unkhair campus IV area, training in the production of ectomycorrhizal inoculants, and training in applying ectomycorrhizal inoculants on agricultural land.

Abstract

Infeksi cendawan terbawa benih merupakan salah satu faktor pembatas dalam pengembangan hutan tanaman sengon. Cendawan yang terbawa benih bisa menjadi penyebab penyakit dan dapat menurunkan produktivitas. Penelitian ini bertujuan untuk mengkaji pengaruh iradiasi sinar gama terhadap kesehatan benih sengon. Benih sengon diradiasi sinar gama dengan dosis 0, 25, 75, 125, dan 175 Gy. Uji kesehatan benih sengon dilakukan dengan menggunakan metode blotter test. Cendawan yang muncul pada benih diidentifikasi berdasarkan ciri morfologi. Hasil penelitian menunjukkan bahwa terdapat delapan jenis cendawan patogen terbawa benih yang teridentifikasi pada benih kontrol dan yang diiradiasi sinar gama, yaitu Aspergillus flavus, Aspergillus niger, Cladosporium sp., Penicillium sp., Phoma sp., Rhizopus sp., Pythium sp., dan Culvularia sp. Jenis Cladosporium sp., Penicillium sp., dan Phoma sp., mendominasi infeksi dan kontaminasi benih sengon pada setiap dosis iradiasi sinar gama. Perlakuan iradiasi sinar gama dengan dosis hingga 175 Gy belum efektif menurunkan nilai persentase infeksi cendawan terbawa benih sengon.

Abstract

Arboretum is an artificial forest that collects various types of plants for educational purposes and plant preservation. The development of an arboretum requires basic information on environmental conditions and tree species suitable for planting. Therefore, this study was carried out with the aim of selecting tree species for the development of the arboretum at Campus IV, Khairun University. The research was carried out at Campus IV of Khairun University which included a study of land conditions, a literature review of local tree species, and tree species selection. A potential location for an arboretum is the triangular park at the campus entrance. This location was planted with the Angsana species (Pterocarpus indicus) in 2019, which has now grown to the pole and tree stage with an average height of 6 m and an average crown diameter of 4.1 m. The soil has a clay texture with a pH of 5.2 and humidity of 55%. Thus, the location can be planted with intolerant tree species on the edges and tolerant species in the middle which has been shaded by angsana vegetation. The tree species selected for species enrichment in the arboretum are local species in the Wallacea region, namely Canarium indicum, Palaquium spp., Syzygium malaccense, Vitex cofassus and Diospyros celebica; timber wood-producing species, namely Swietenia macrophylla and Ochroma pyramidale; producer of gaharu NTFPs, namely Aquilaria malaccensis; and shade-tree for aesthetics, namely Tabebuia rosea.
