Abstract

Weed control must use the right dose of herbicide so as not to leave a residual effect on cultivated plants and soil. This study ains to obtain the most appropriate dose of herbicide. Herbicide used in this study were methyl methulfuron and acetic acid combined. This study used a randomized block design (RCBD) witch 2 factors, factor A was asetic acid and factor B was methyl methulfuron and there were 12 treatment combinations with 3 replications. This research was conducted in the practicum of the Departement of Plantation Plant Cultivation, Lampung State Polytechnic. The total research plot was 36 experimentals units. The dosage levels levels of methyl methulfuron tested in this study were: 0%, 55%, 75%, and 105%. While the dose of acetic acid is: 0%, 50%, and 70%. Observations made in this study were weed vegetation analysis, weed cover percent, weed dry weight, Summed Dominance Ratio (SDR), and Community Coefficient Value (C). SDR values indicate that Panicum dicotomyflorum weed, Ricardia brasiliensis, Euphorbia heterophyla, and Cyperus rotundus are the dominant weeds. The results of this study indicate that there is no effect on the dose of methyl methulfuron herbicide, acetic acid, and interactions on methyl methulfuron herbicide and acetic acid on weed control in sugarcane fields (Saccharum officinarum L.).

Abstract

Manure is a fertilizer derived from animal manure, which can improve the structure of peat soil and provide nutrients for lettuce plants (Lactuca sativa L.). Peat soil is a type of soil that has many obstacles in cultivation including acidic pH, low nutrient availability such as N, P, and K. Manure can be used in solid and liquid forms. This study aims to determine the dosage and the appropriate way of giving chicken manure to the yield of lettuce and the nature of the soil after being given chicken manure. This research has been carried out from April to June 2018 on experimental land, Agronomy Laboratory. This study used a Completely Randomized Design (CRD) with 7 treatments namely without fertilizer application (control), 37.5 g solid fertilizer of chicken manure, 75 g solid fertilizer of chicken manure, 112.5 g solid fertilizer of chicken manure, 37.5 g of solid fertilizer thawed chicken manure,75 g of solid fertilizer thawed chicken manure, 112.5 g of solid fertilizer thawed chicken manure. The results showed that 112.5 g  solid manure from chicken manure was the appropriate dose to increase the growth of lettuce plants, namely plant height (15.48 cm), leaf width (11.60 cm), number of leaves (11.00 strands), weight plant (37.83 g), weight root plant (3.48 g), and increasing the total N content of the soil (0.40%).

Abstract

Indonesia is one of the centers of durian diversity in the world and one of the regions that makes durian a superior local fruit crop is Jember and Banyuwangi. Clustering is useful to facilitate the search for certain features of the type of durian. This study aims to determine the durian grouping in two districts namely Jember and Banyuwangi. The materials used were local superior durian fruit and characterization questionnaire. Research using descriptive methods. Characterization data will be analyzed using NTSYS software.The results showed that local superior durian fruit were grouped into 2 groups based on morphological characters. Cluster 1 consists of 4 durians namely Klemben, Hijau, Bajul, and Lambau. Cluster 2 only consists of durian Musang King. Based on the chemical content of durian fruit, durian Lambau from Jember has the highest water content of 75.52%, Musang King from Banyuwangi has a fat content (2.29%), Bajul from Jember has the highest fiber content (11.89%), and Hijau from Banyuwangi has the highest protein (3.14%) and sugar (26.08%) content. Based on PCA showed that Musang King and Hijau have similirity on some morphological characters and chemical fruit contents. The results of correlation analysis of morphological characters and chemical content of durian fruit showed that leaf length was positively correlated with leaf width and protein content. Leaf width is positively correlated with sugar content. Fruit weight is positively correlated with water content.

Abstract

This research aims to determine the resistance of variance of soybean (Glycine max L) varieties to Lamprosema indicata in the field. This research was conducted in Banyumas Village, Stabat sub-district, Langkat Regency, North of Sumatra, from March 2019 until May 2019. This research used by a descriptive method with observational techniques consisting of 15 plots and 225 sample plants. The results of the study showed the resistance and intensity of attacks larvae of L. indicataon leaf of each variety, namely the Dena (average of 10.33 larvae and 24%); followed by Dega consists of 8.17 larvae and 18%, then Detap showed of 6.00 larvae which 12%. Meanwhile, Devon (7.83 larvae and 14%) and Anjasmoro with an average of 7.67 larvae and 13%.Variety of soybean of Data was resilience of attack of L. indicate in the field, while Dena is very susceptible to attack of L. indicate.

Abstract

This unlicensed gold mining activity (PETI) can have a positive impact on the economy of the community, in the form of increased incomes so that it can improve the welfare of the community. However, besides having a positive impact, PETI's activities will harm the environment around the mining area. The negative impact caused by mining activities is environmental damage in the form of a decrease in land quality as indicated by a decrease in physical, chemical and biological soil quality. The purpose of this study was to determine the nutrient content and the total of microbes in former PETI soils in sub-districts of the Kuantan Singingi Regency. The parameters observed were analysis of nutrient content consisting of analysis of sand, dust, clay, soil pH, C-organic, N-total, P2O5, K2O, interchangeable cations, CEC, a saturation of bases, Aluminum Saturation, and analysis of total soil microbes. The results showed that the Singingi sub-district, Central Kuantan sub-district, Sentoja sub-district, and Logas Tanah Darat sub-district has the texture of sand soil clay to sand, the content of pH H2O Land classified as fertility is very sour, C-Organic (%), Ca-dd, Nitrogen-Total (%), Mg-dd and CEC with very low fertility criteria, C/N Ratio with low to very low fertility criteria, K-dd content with low criteria, Na-dd with moderate to very high criteria, aluminum saturation is very high with wet saturation the fertility criteria are low. The total microbes in the Sub-district of Sentoja Raya and Logas Tanah Darat Sub-district are much higher than Singingi Sub-district and Central Kuantan Sub-district.

Abstract

Rice is a cereal crop that belongs to the graminae family of high economic value, and is the main food for more than a portion of the world's population. This study aims to determine the relationship genetic of rice in Kampar by RAPD marker. Eight genotypes of rice from district in Kampar were amplified using eight primers (OPA 5, OPB 7, OPC 19, OPD 2, OPD 3, OPD 8, OPD 11, and OPD 13). The analysis of molecular data was performed by using NTSys pc -2.02 and GenAlex 6.1 . The results of the amplification of rice produced 48 loci with DNA band sizes obtained ranging from 350-1700 bp. The average percentage of polymorphic loci of the eight primers was 49.80%, where the highest percentage of polymorphic loci produced by OPA-7 primer was 75%, while the lowest polymorphic locus percentage was observed in OPD-13 primer which was 14.28%. The value of genetic distance between rice from Kampar in this study is in the range of 0.06 - 0.37. At a genetic distance of 0.79, rice plants can be grouped into two groups, namely the first group consisting of sokan and coku. The second group consisted of suntiong, korean , cupak putio, kuniong, jangguik, and cupak tenggi. The results of this study are expected to be taken into consideration in developing rice breeding strategies in the future.
