Abstract

East Java Province supplies one third of the national peanut production. The farmland of peanut production centers in the region is a coastal area prone to salinity. The use of variety adaptive to salinity stress is an effective strategy to cope sainity problem and to optimize the use of salt-affected land. The aim of the research was to evaluate the adaptability of peanut varieties to salinity stress.The research was conducted in the 2018 dry season in the saline paddy field in Gesikharjo Village, Palang Sub District, Tuban Regency with EC 14.54 dS/m. The treatments consisted of seven groundnut varieties (Singa, Singa, Kancil, Takar 2, Bison, Hypoma 2, Tuban, and Jerapah), using a randomized complete design, four replications. Observations consisted of growth parameters, yield and yield components, proline and macro nutrient (N, P, K) content. The results showed that high salinity stress reduced seed germination, plant growth, yield components and yields of all varieties tested. Based on the ability to survive and yield, Singa variety have showing higher tolerance to salinity stress or more adaptive than other varieties, while the lowest one was found in Jerapah variety. The salinity tolerance of Singa variety did not indicate to be associated with high proline content, but it seem more related to the ability to absorb higher N, and keep K high to reduce negative effect of Na.

Abstract

The glow of corruption criminal in this country is extroudinary over limit so it needs some efforts to fight against it totally and finished. Although there are regulations for corruption act, but it doesn’t abolish yet or over come this problem, this, because the corruption has become a culturre system and rooted also become life style of the nation. So it’s rather difficult to abolish the corruption criminal via regulations.Therefore it’s need to reconstruct a nation mind set, life style, and moral by digging up the value of Pancasila as the cristalization of caracter, behaviour and personality for early Indonesian people.It is very urgent to revitalize the value of Pancasila when the nation has been suffered from bad moral, because the revitalization is real effort to reconstruct and replace the nation morality in right position as it has moved far from nation morality value that is Pancasila.A Pancasila revitalizasion is process to revitalize aboth function and occupation of Pancasila as philosophy of noble family and state. As well as make it as resource of all law resources in Indonesia country. So that Pancasila as standard, for Indonesian people in a noble family and state life.Keyword: Revitalisasi, Norma Hukum, Korupsi, Pancasila.

Abstract

The productivity of cassava in acid dryland is generally still low. Fertilization, land amelioration, and superior varieties are the main solutions for increasing cassava productivity. This research aimed to determine the response of high-yielding varieties and fertilization technology packages to the growth and yield of cassava in acid dryland of Sukaharja Village, Warung Kiara District, Sukabumi Regency, West Java. The contents of organic carbon, nitrogen, and magnesium of the soil is below the minimum threshold, so the application of N fertilizer, organic matter, and ameliorant is expected to increase plant growth. The research consisted of two treatment factors: two cassava varieties and three fertilization technologies. The treatments were arranged in a completely randomized split-plot experimental design with three replications with variety as the main plot and fertilization technology package as the subplots. The treatment effect was observed on the character of plant height, wet biomass weight, stem diameter, number of tubers, tuber length, tuber diameter, tuber weight (large and small) per plant, and tuber yield per plot to be converted per ha. Tuber quality was observed by observing water content, percent dry matter, and starch yield. The results showed that the fertilization technology package increased plant height, fresh biomass weight, stem diameter, large tuber weight per plant, and yield per hectare in both varieties. Differences in varieties and fertilization technology packages have no effect on starch levels.

Abstract

Aluminum Detoxification by Humic Substance Extracted from Compost of Organic Wastes (S Winarso, E Handayanto and A Taufiq):  Humic substance could control the activity of metal as well as exchangeable aluminum (Alexch) on acid soil. The humic substance extracted from compost of agricultural waste is rarely conducted. The objective of research was to evaluate the effect of humic substance concentration and sources to pH and Al suspension. The research had been conducted in the Soil Laboratory of Agricultural Faculty of Jember University from April to July 2009. The humic substance used in these researches was extracted from compost of rice straw (RS), soybean straw (SS), cassava starch solid waste (CSSW), and empty bunch of oil palm tree (EBOPT). The humic substance concentration treatments were 0, 10, 20, 30, 40, 50, 75, 100, 150, 200, 250, and 300 ppm. Result of the analysis showed that characteristic of humic substance was difference depending on the source material used. The humic substance extracted from SS contain total base cations (K, Na, Ca, Mg) higher (1.17%) compared with CSSW (1.07%), OPT  (0.87%), and RS (0.69%). While the humic substances extracted from RS contain total organic acid (Acetic, Fumeric, cetoglutamic, Sucsinic, Propionic, Butiric, Ocsalic, and sitric acid) higher (157 ppm) compared with EBOPT (129 ppm), SS (115%), and CSSW (108%). Among these organic acids, acetic acid was highest concentration (> 34.51% of total acid). The addition of humic substance increased pH and decreased aluminum concentration of the suspension. The higher pH increment and Al concentration reduction took placed in the suspension treated with humic substance from SS compost. The correlation between decreasing Al concentration with humic substance concentration which explained chelation was higher (r = 0.97) than decreasing Al concentration with increasing pH which explained precipitation (r = 0.93). Based on these research results, it can be concluded that humic substance extracted from agricultural waste have a good prospect as a soil ameliorant to increase soil pH, detoxify soil aluminum, and increase soil P availability on acid soil.

Abstract

Humic substance (HS) extracted from composted agricultural waste contains organic acids that potential for an acid soil amandement. Functional group of COOH and OH in synthetically organic acid is higher than in HS originated from composted agricultural waste. Addition of synthetically organic acid to the HS may increase its functional group and therefore it will increase effectiveness in detoxifying aluminum (Al) and desorpting phosphorus (P) from an acid soil. Objective of reseach was to determine effect of synthetic organic acid addition to HS extracted from composted organic matter in desorpting P and detoxify Al. Research was conducted at Soil Laboratory of Agricultural Faculty of Jember University from February to May 2010. Treatment consisted of combination of four levels of HS concentration extracted from composted rice straw (0; 1,000; 2,000; and 5,000 mg kg-1) with two kind of synthetic organic acid: ethylenediaminetetraacetic acid (EDTA) and acetic acid (CH3COOH) at concentration of 5 mM. The treatment laid out in a randomized complete by design with three replications. Ultisol collected from Kentrong Banten was used in this reseach. Observation consisted of pH, Al and P concentration in the suspension at 0, 1, 2, 3, and 4 weeks after incubation. The result showed that EDTA or acetic acid treatment at concentration of 5 mM effectively increased soil pH and decreased exchangeable Al (exch-Al). However, EDTA was more reactive and having higher capability in increasing pH and detoxifying exch-Al than acetic acid. Humic substance extracted from composted rice straw at concentration of 1,000 to 5,000 mg kg-1 also effectively increased soil pH, decreased exch-Al, and increased P availability during a 4 week incubation period. The HS effect in Al detoxification and P desorption in acid soil could be boosted by addition of EDTA or acetic acid synthetic

Abstract

Acidic dry land in Lampung is potential for soybean development area. Low soybean yield in farmer level is one of factor causing its’ low competitiveness. Soil fertility is the main constrain related to low yield of soybean. Objective of the research was to diagnose a cause of poor soybean growth on dry land Ultisol at Sukadana sub District, East Lampung District. Soil and soybean plant samples were collected from farmers’ field at Sukadana ilir village during planting season April – July year 2010. Plant and soil samples were taken when soybean at R1 stage (starting to bloom) using stratified random sampling method. The result showed that variability of soybean growth on Ultisol at Sukadana, East Lampung related to variability of soil pH, exchangeable Al, exchangeable K, Ca, and Mg. The poor soybean growth was due to low soil pH, high exchangeable Al, low exchangeable K, Ca, and Mg.

Abstract

The acidic soil is generally less productive due to soil pH ranging from 3.1 to 5.0. However, it could be solved through soil amelioration, planting tolerant varieties to acidic soil condition, and a combination of both. Twenty peanut genotypes including two check varieties (Jerapah and Talam 1) were evaluated on dolomite-ameliorated and non ameliorated soil. In the greenhouse, the treatments were laid out in factorial design with four replications, while in the field using strip plot design with three replications. Assessment of tolerance was using Stressed Tolerance Index (STI) according to Fernandez (1992). Results showed that dolomite application at dose equivalent to 0.5 x exchangeable Al was optimal in improving peanut growth, and peanut yield on acidic soil. Lines of GH3 (G/92088/92088-02-B-2-8-1) and GH 4 (G/92088/ 92088-02-B-2-8-2) genotypes had high STI with average yield of 2.47 tha-1 and 2.62 t ha-1 of dry pods and potential yield of 4.05 t ha-1 and 3.73 t ha-1 of dry pods, respectively as well as check varieties (Jerapah and Talam-1). It is concluded that peanut genotype of G/92088//92088-02-B-2-8-1 and G/92088//920 88- 02-B-2-8-2 were adaptable and tolerance to acidic, and tolerance of peanuts on acidic soil condition were probably controlled by the buffering mechanisms. Keywords: peanut, acidic soil, tolerance

Abstract

Salinity has become a serious problem in the production of food crops in Indonesia, especially in coastal areas. Mungbeans is one of commodities which can be grown in coastal areas during the dry season. Research to evaluate tolerance of mungbean genotypes to salinity stress was conducted on saline soil (EC 11.4 dS m-1) at Lohgung Village, Brondong Sub District, Lamongan District during dry season May-July in 2016. A 100 of mungbean genotypes were evaluated using a randomized block design, replicated twice. The majority of the genotypes (82%) were categorized between sensitive to very sensitive to salinity stress. All of the genotypes grew normally to generative phase and produced 2-9 pods per plant with seed yield ranged 0.04-0.60 ton ha-1. The tolerant genotypes had higher plant height, stover weight, and yield than the sensitive genotypes. Six genotypes indicated as very tolerant to salinity stress (EC: 9.24 to 15.06 dS m-1) i.e., MLG 1065/Vima1-279, MMC 464c-gt-4-0-3, MMC 678-8c-gt-5, Vima 1/MLG 1065-286, MLG 1065/Vima1-276 and Vima1/Sampeong//Vima1-249. Seven genotypes indicated as tolerant to salinity stress i.e., Vima1/MLG1065-290, MLG1065/Vima1-272,  MLG1065/Vima1-274, Vima1/MLG 1065-287, Vima1/MLG 1065-276, MMC 267c-mn-1-1-11, and VIMA 1/MLG 1065-288. These selected genotypes were potential to be developed into new mungbean variety tolerant to salinity.Keywords: electrical conductivity, growth, yield, selection, Vigna radiata

Abstract

Agricultural lands affected by salt facing complex problems associated with soil salinity and the toxicity effects of Na cation. Soil amelioration and mulching is an alternative to alleviate negative effect of salinity. Objective of research was to identify effective ameliorant, and effect of mulching in improving growth and yield of groundnut on saline soil. The research had been conducted on saline soil (soil EC 12 dS/m) in Lamongan during dry season of 2016, using Hypoma 2 cultivar. Treatments that consisted of two factors were arranged in a split plot design with three replicates. The main plot was mulching (without mulching and mulching with 3.5 t/ha of rice straw), and the sub plot was soil ameliorations (control, 120 kg/ha K2O, 750 kg/ha S, 5 t/ha gypsum, 5 t/ha manure, and 1.5 t/ha of gypsum + 5 t/ha manure). Results showed that mulching, and amelioration with 120 kg/ha K2O, 750 kg/ha S, 5 t/ha gypsum decreased soil EC, but could not improve groundnut growth and could not retard chlorophyll degradation because the soil was EC still high (12.5 dS/m). The higher yield (1.49 t/ha dry pods) can be obtained by amelioration with 750 kg sulphur/ha combined with mulching

Abstract

Agriculture lands in coastal areas face the risk of increasing salinity due to the influence of sea water. Salinity poses complex problems for plants at all growth stages which are difficult to be addressed. Trichoderma is a microorganism known to promote plant growth and to induce plant tolerance to abiotic stresses including salinity. The research aimed to evaluate effective Trichoderma for improving groundnut growth and yield in a saline environment. The research was conducted on saline soil (EC >8 dS/m) at Gesikharjo Village, Palang Sub District, Tuban District from July to October 2019. Treatments were combinations between N and P fertilization, and four Trichoderma strains and these treatments were arranged in a randomized completely block design with six replicates, using Hypoma 1 groundnut cultivar.  Soil fertility and salinity, growth, yield and yield components were recorded as observed parameters. The results showed that NP fertilization on high salinity soils (ECs of 8.80-15.91 dS/m) with low N and high P had no significant effect on all variables compared to those of N fertilization. Applications of Trichoderma increased plant height and minimized plant death as indicated by a higher percentage of plant population at harvest compared to that of without inoculation. Among the four Trichoderma strains, Trichoderma #3 and Trichoderma #4 showed more effective than the other two strains in improving plant growth based on the shoot dry weight at the R1 phase, plant height and percentage of plant population at harvest. The positive effect of Trichoderma #3 and #4 could be due to the ability to promote plant growth as well as to induce plant resistance against salinity stress. The results suggested that Trichoderma was effective to alleviate salinity stress on groundnut crops. This research was the first trial carried out in the field and therefore needs to be further investigated, including Trichoderma formulations and application techniques.
