Abstract

Sugar palm is one of local plants spesies that may potential for reclamation program because can be planted under the stands of forest crops. Forest crops can be shade seedlings sugar palm from direct sunlight because the growth of sugar palm is relatively slow. Sugar palm can be useful even without cutting down the trees. Previously, sugar palm had been planted at PT Berau Coal and had produced fruit. The research was conducted at coal post-mining land of PT Bukit Asam, Tanjung Enim, South Sumatera. The research using combination of AMF and liming treatment is as follows, ie MaK0 (control), Mak1 (seedling with AMF without inoculation; liming 30 g plant-1), MiK0 (AMF indigenous seedling inoculation; without liming), MiK2 (AMF indigenous seedling inoculation, liming 60 g plant-1), MmK0 (AMF mycofer seedling inoculation; without liming), and MmK3 (AMF mycofer seedling inoculation, liming 120 g plant-1). The results showed that sugar palm could be grown in the coal post-mining land. The combination of AMF and liming treatment did not significant effect on observed variables of plant height, rachis length, diameter, leaves number, number of spore and root cholonization. Sugar palm seedlings that have been infected with AMF could be grown and provide a good growth response even without liming.Keywords : Arbuscular Mycorrhizal Fungi (AMF), marginal land, sugar palm

Abstract

Aluminium (Al) phosphotoxicity is the most common constraint in acidic soil. Information on potential Al phytotoxicity is required in revegetation planning, monitoring of this information is generally done through laboratory analysis procedure in the laboratory that requires high cost and time. The purposes of this study were to test the method of quick detection of Al phytotoxicity with sorghum bioassay. Soil samples taken from post-gold mining land in Bolaang Mongondow Regency of North Sulawesi Province were analyzed for soil physical and chemical properties then planted with numbu varieties of sorghum with complete randomized design, sorghum growth performance response and its correlation with soluble Al and pH were analyzed and then the symptoms occured from Al-toxicity on sorghum were observed. Sorgum responds to Al-toxicity by showing symptoms of shortening and thickening of the roots and stunted growth performance. Sorghum growth performance has significant negative correlation with soluble Al concentration on soil, and soil acidity showed a stronger correlation. Al-phytotoxicity symptom in sorghum at pH below 3.7 begins to be clearly visible and easily observed, this distinct appearance difference makes sorghum potential to be used as bioindicator to detect Al- phytotoxicity on the soil.Keywords: Aluminium phytotoxicity, sorghum, post-mining revegetation

Abstract

Gosale (Syzygium malaccense (L.) Merr. & L.M.Perry) that belongs to the Myrtaceae family is one of the leading local plant species grown in Halmahera, North Maluku. Some problems in gosale breeding such as limited seed availability, low seed production due to seasonal fruiting and the nature of seeds that can not be stored for a long period (recalcitrant), suggest an alternative new production technique through a vegetative propagation (shoot cutting). Moreover, Improved seedling quality can be attempted by AMF inoculation, in which AMF at shoot cuttings play a role in initiating the formation of adventive roots. This study was conducted for 9 months using completely randomized design (CRD) with indigenous AMF inoculation treatment. The results showed that gosale cuttings that planted with indigenous AMF inoculation were effective at all observed variables. Inoculum AMF inoculated without the addition of host plant Pueria javanica at gosale shoot cuttings suggested the best treatment. The treatment of inoculum AMF from Kusumadehe (M1) obtained the best result in the variable of plant height increase, dry weight of shoot, dry weight of root, root shoot ratio), and seedling quality index. While the treatment of Inoculum AMF from Soakonora revealed the highest result in the variable of plant diameter increase and AMF colonization.Keywords: gosale, shoot cuttings, AMF, Pueraria javanica, West Halmahera

Abstract

The rubber tree stump is a source of white root fungus inoculums and as a source of infection that causes the death of rubber plant. The emergence of this disease is closely related to the cleanliness of the land such as leftover trees or stumps, shrubs and bushes which stacked or still in the ground. One of the symbionts organisms found in gut of termite and play a role in the decomposition of cellulose, are bacteria. Termite are social insects that are efficiently decompose lignocelluloses with the aid of their associated microbial symbionts located in termite gut. The purpose of this study was to obtain cellulolytic bacterial isolates are derived from gut of termite and getting an cellulolytic which showed the best ability in decomposing rubber tree stumps. The result termite samples from oil palm, rubber, and dry wood contain cellulolytic bacteria characterized by clear zones around bacterial colonies. Bacterial isolates showing the ability to degrade cellulose are 31 isolates and five isolates are safe for plants, animals, or mammals. The three bacterial isolates (NK 4, NS 4, and NS 5) used in the test on rubber tree stumps able to decompose rubber tree stump. Bacterial isolates were each obtained NK 4 13.52%, NS 4 18.40% and NS 5 17.88%.Keywords: bacteria cellulolytic, rubber tree stumps, termite

Abstract

Continuous mining activities of limestone operation may cause negative impact such as environmental damage and reduction of soil quality (physically, chemistry, or biological). Revegetation is the process to increasing productivity of postmining limestose land. Acacia mangium is one of fast growing species that can grow in marginal land, symbitotic with rhizobium bacteria, and high economic value. The purpose of this research are to test the response of coconut shell charcoal and cow feces (bokashi) addition to the growth of akasia (Acacia mangium) seedling on postmining limestone soil and to find out the optimum dose of coconut shell charcoal and cow feces (bokashi) addition. This research used a complete randomized design factorial with two factors, each factor have four degree. First factor is addition of coconut shell charcoal and second factors is addition of cow feces (bokashi). The result of this research showed that coconut shell charcoal and cow feces (bokashi) addition on postmining limestone soil gives positive influence towards the amount of root nodule. But not affect other parameters such as height, diameter, total wet weight, total dry weight, and root tops ratio. The interaction between addition 10 g of coconut shell charcoal and 20 g of cow feces (bokashi) is the best composition for a significant effect in improving the amount of root nodule of A. mangium seedling by 78.58%. Very high levels of Ca in the soil medium will be toxic to the acacia plant.Keywords: Acacia mangium, bokashi cow feces, coconut shell charcoal, limestone mining
