Abstract

The use of polybags and topsoil planting media often causes the development of seedlings is not maximal because the topsoil is too dense. As well as continuous inorganic fertilization is not balanced with the provision of organic fertilizers cause the planting media to become dense. One of the efforts in overcoming this is by providing compost. Compost can improve soil fertility and can improve soil structure. This research was conducted with the aim to find out how the influence of banana stem compost fertilizer on the growth of rubber seedlings (Hevea brasiliensis Muell.Arg.) Clone PB 260 one umbrella. The design used in this research is Randomized Block Design (RAK) with one factor, namely banana stem compost with 5 levels that is without composting banana stems (k0), 250 g / polybag (k1), 500 g / polybag (k2), 750 g / polybag (k3) and 1000 g / polybag (k4) with 5 group. The observed variables are the increase in the length of grafting buds (cm), the increase in the number of leaf strands (strands), the increase in the diameter of the graft buds (mm), the time of the appearance of the second umbrella bud (day), the dry weight of the header (g) and the dry weight of the roots (g) of rubber seedlings. The results showed that the influence of the treatment of banana stem compost fertilizer does not differ noticeable to the growth of rubber seedling clones PB 260 one umbrella on all parameters observations.

Abstract

The aim of this study was to test several endophytic fungi isolates with high antagonistic power against seed borne fungi in vitro and their effect on the growth of chili (Capsicum annuum L.) seedlings in vivo. This research was conducted at the Plant Disease Laboratory and Greenhouse Faculty of Agriculture, Riau University from October 2018 to February 2019. This research was conducted experimentally using a completely randomized design (CRD) consisting of 5 treatments and 4 replications. The treatment of endophytic fungi was applied using the seed immersion method. The results showed that giving the endophytic fungi Rhizictonia sp., Cephaloporium sp., T. virens from oil palm roots and T. virens from oil palm stems were able to suppress the incidence of seed-borne pathogenic fungi Fusarium sp., Colletotrichum sp. and Aspergillus sp.. Provision of endophytic fungus T. virens from oil palm roots can increase seed germination capacity by 14%, number of live seeds by 17% and increase seedling height and leaf number.

Abstract

Until now, Indonesia's rice production has not been able to meet all the needs of the community. In the evaluation of seeds there are often seeds that are still abnormal and have not germinated. From the description above, the researcher is interested in examining "Test of immersion time and biolemi POC dosage on the growth of rice seeds of Inpari 32 (Oryza sativa L.) variety". This research was conducted in Perbaungan Village, Bilah Hulu District, South Labuhanbatu Regency, North Sumatra Province. This research used inpari 32 rice varieties with factorial randomized block design (RAK) method, with two factors, namely soaking time and biolemy POC. Soaking time affects the growth of rice seedlings on the parameters of seedling height, germination and root length. The application of biolemy liquid organic fertilizer had no significant effect on all parameters. The interaction of immersion time with the application of biolemy liquid organic fertilizer gave no significant effect on all observation parameters.

Abstract

The research objective was to analyze the supply chain of the sago industry in the Meranti Islands Regency. Case Study PT. Nasional Sago Prima (PT. NSP). The research was carried out in March - October 2020. The research method was a survey. The analysis used: qualitative and quantitative. Qualitative analysis to describe the mechanism and flow pattern of the supply chain for the sago industry. Meanwhile, quantitative analysis is used to analyze components and supply chain activities. The results showed: 1). The supply chain mechanism for the sago industry that occurs is the creation of collaboration and coordination between supply chain actors from upstream to downstream. The flow pattern of the supply chain, which consists of raw material flow, product flow, financial flow and information flow, went smoothly. 2). The resistance of the supply chain for the sago flour industry are: A). 70% of the raw material for sago tual is supplied from outside the company, because the nucleus plantations have not yet entered the full harvest period. B). Inefficient processing costs due to: the cost of using electricity and the high cost of water filtration processes.

Abstract

Purun is one of the endemic plants that naturally grows wild in peat and swamp areas. Purun is commonly found in peat and swamp areas in Indonesia, including in East Kalimantan, especially in Kabupaten Kutai Kertanegara. Purun belongs to the Cyperaceae family. This plant is a typical plant in swamp land. Swamp land is land for a long time during the year is always saturated with water or inundated. Purun is a plant that lives in the wild naturally in areas of peat swamp, tidal swamp and river areas that are acidic sulphate.There are three types of purun known in Kalimantan, namely purun danau, purun tikus and purun bajang. The purun danau (Lepironia articulata Retz. Domin.) has a fundamental difference when compared to the purun tikus and the purun bajang, which is much larger in size than the purun tikus and the purun bajang and has leaves that are tougher like woody and more clearly lined than other. Purun danau also has a cavity that is similar to a bamboo stick. The objectives of the study were to 1. determine the character of purun danau plants in the natural humid tropics habitat; and 2. Knowing the characteristics of purun danau plant habitat. The research design used in this research is descriptive or descriptive research. The results showed that: 1. the morphological character of the purun danau was in the form of a cylindrical stem like a pipe that grew elongated with a tapered tip, had thin partitions that filled the inside, the bulkhead was solid at the base and the stem was shiny green. The outer part of the base is white and covered with leaves shaped like a reddish brown sheath. The tapered end of the stem then grows into a compound flower which will contain many seeds in the generative phase. Purun danau flowers are compound flowers and are located at the end of the stem. The roots of purun danau are fibrous and grow with the stolons. 2. The purun danau habitat is characterized by the presence of water, either always stagnant or flowing water with varying heights (between 100 cm to 300 cm). In addition to the presence of water, purun habitat is also characterized by acidic soil pH conditions (4.10-5.20) and open land without shade. In addition to adapting well in acid sulphate soils, purun danau are also able to absorb heavy metal elements such as Pb, Cd and Zn.

Abstract

Banana (Musa sp.) is a fruit plant that commonly cultivated in the tropics.  Indonesia has a variety of banana cultivars, each cultivar may a different susceptibility to pests and diseases. This study aims to identify the damage intensity of banana scab moth (Nacoleia octasema Meyrick) on some banana cultivars. The Survey was conducted on banana plantation, while the sample was selected using random sampling. Six banana cultivars were observed, namely Kepok, Raja Nangka, Raja Bulu, Raja Tawi and Mas Kirana. The research variables were the damage intensity of banana scab moth and the physical character of the fruit. The damage intensity recorded the bananas fruit showing the symptoms of scab moth. The result were analyzed by using t test and presented in table or/ and graph. The results showed that the damage of banana scab moth was recorded on all banana cultivars. So, there were not banana cultivars absolutely resistant to N. octasema. The cultivars of Kepok and Raja Nangka were preferred, while Mas Kirana was less preferred by N. octasema. The attack of N. octasema larvae began from the first hand position, whila the highest damage was recorded in the last hand position of banana bunch. The damage intensity of N. octasema on the lowerside of each hand position of banana bunch was significantly higher than the upperside, that even no damage
