Abstract

[SPATIAL ANALYSIS OF MATERIAL DISTRIBUTION AND CHEMICAL PROPERTIES OF VOLCANIC ASH FROM THE ERUPTION OF MT. SINABUNG IN 2019]. Mount Sinabung, located in Karo Regency, North Sumatra, first erupted in August 2010 and continued from 2013 to 2022. As one of the parent materials for fertile soil, volcanic ash reserves large amount of nutrients. The research was aimed to determine the chemical characteristics of volcanic ash and to map the distribution of volcanic ash from Mt. Sinabung eruption material in 2019. This study examines 22 samples of the of volcanic ash collected based on a terrestrial survey with the grid method. The results showed that volcanic ash within a radius of 3-5 km from the center of the eruption (total area 1,402.83 ha) have a pH-H2O ranged from 5.30 to 6.27 (acid to slightly acid), Mg > Na > Ca > K, in order of base cations, with moderate to very high criteria, available P ranged from 35 – 165.96 mg/kg (very high), and CEC ranged from 12.92 – 21.78 cmol/kg considered low to moderate. Therefore, the volcanic ash deposits can provide a significant quantity of nutrients for future soil fertility in agricultural areas affected by eruptions.

Abstract

[HUMIC COMPOUND APPLICATION FOR SOIL QUALITY IMPROVEMENT AND ENHANCEMENT OF PEPPER GROWTH]. Pepper (Capsicum Annum) is a strategic commodity that contributes to Indonesia's economy. The price of pepper fluctuates due to the instability of pepper production, which is influenced by multiple factors such as decreasing of soil fertility. Soil conditioner can help to improve soil fertility. The purpose of this research was to determine the effect of humic compounds application on pepper cultivation to improve soil fertility and increase the growth and yield of pepper. The research was conducted from February to August 2021 at the IPB Pasir Sarongge Experimental Field in Cianjur, West Java. The study was conducted using a Completely Randomized Group Design (CRGD) with one factor, humic compound solution concentrations of 0, 2.5, 5, 7.5, 10, and 12.5 mL/L, with each level repeated four times. Duncan's Multiple Range Test (DMRT) was used to separate the mean of the data after variance analysis. The result showed that humic compound application can improve soil fertility, growth and yield of pepper plants as indicated by increasing the value of Cation Exchange Capacity (CEC), decreasing potassium leaching rate and increasing all growth and yield characters except the yield per plant character. The application of 12.5 mL/L humic compounds increased CEC, decreased potassium leaching rate to 0%, increased plant height (37.40%), number of branches (56.72%) and number of fruits (57.81%). The application of humic compounds at 10 mL/L   increases the weight of 10 fruits (30.78%), yield per plant (27.56%), yield per plot and predicted yield per hectare (47.58%).

Abstract

[BIO-COMPOSTING OF SOLID OIL PALM WASTE WITH DIFFERENT DECOMPOSERS AND PHYSICOCHEMICAL CRITERIA FOR COMPOST QUALITY ASSESSMENT] The quantity of produced wastes by oil palm industry is increasing and may lead to significant environmental concerns and the use of these wastes as compost is considered to overcome their negative impacts. However, very few studies have been conducted to develop an effective composting process of the biomass waste using different decomposers. Therefore, the objective of this study was to assess the different physicochemical and biological quality of compost produced by bio-composting of solid oil palm waste with three different commercial decomposers. This study was conducted from September 2021 to November 2021 at the Compost House, Faculty of Agriculture, University of Lambung Mangkurat. A certain period of bio-decomposition process was employed by using commercial bio-decomposers. Physicochemical and biological analyses of the composted solid waste were conducted after decomposer application. The experiment consisted of four treatments (i.e., solid oil palm waste + chicken manure, solid oil palm waste + chicken manure + EM4, solid oil palm waste + chicken manure + M21, and solid oil palm waste + chicken manure + Tangguh) and they were arranged in completely randomized design with three replicates. Results showed that quality of all compost met the SNI 400 standard except for pH, organic-C, and C/N ratio for the treatment without bio-decomposer,  pH and C/N ratio for the treatment EM4 bio-decomposer, water content, pH, organic-C, and C/N ratio for M21 bio-decomposer, and pH, organic-C, and C/N ratio for the treatment with Tangguh bio-decomposer, respectively. The maximum germination test obtained was recorded at 70%, 80%, 94%, and 86% in compost media without bio-decomposer, with EM4, 94% with M21, and with Tangguh, respectively. The maximum number of microbes were recorded at 3.2 x 106 µg/g, 2.9 x 105 µg/g, 1.3 x 106 µg/g, and 8.0 x 105 µg/g for compost without bio-decomposer, with EM4, with M21, and with Tangguh bio-decomposer, respectively.

Abstract

[RESPONSE OF IN VITRO SHOOT INDUCTION ON VANILLA PLANTS (Vanilla planifolia) TO THE CONCENTRATION OF BAP AND 2,4-D]. The seeds of V. planifolia A. are plantation product that can be used as food scent and industrial ingredient. On its progression, vanilla farmers propagate by cuttings. The process of vanilla cutting has ben anobstacle in terms of pathogen attack and slow grow, and cuttings propagation is considered unable to meet the demand for seedlings. Tissue culture is a technology that can overcome problems in the vanilla propagation process. The research took place from January to June 2022 at the University of Jember, Bondowoso Campus.  The research  aims to determine the response of shoot induction to the addition of hormones. The completely randomized design (CRD)  was used with 2 factors,the BAP at concentration of 0 , 0.5  and 1 ppm combined with 2,4-D at concentrations of 0.5 , 1 and 1.5 ppm. The data were analyzed using ANOVA with a significant level of 5% and continued with the DMRT test with a significant level of 5%. The results showed that there was an interaction between concentration BAP and 2,4-D in vitro vanilla culture. The treatment without hormones showed a longer shoot formation and the combination of 2,4-D with a higher concentration caused an inhibition in shoot elongation. The combination treatment of 0.5 ppm BAP and 0.5 ppm 2,4-D also 1 ppm BAP and 0.5 ppm 2,4-D had the best response indicated by the highest shoot length and faster shoot formation.

Abstract

[THE EFFECT OF MICRO-COMPOUND FERTILIZER AND HUMIC ACID ON AVAILABILITY OF P AND  UPLAND RICE YIELD IN COASTAL LAND] Indonesia’s coastal areas are potential  for the  agriculture. However, coastal areas have poor physical, chemical and biological soil properties that unfavorable  to the growth and yield of plants. Upland rice is a food crop that can be developed on coastal land using  humic acid technology and micro-compound fertilizers. This study aims to determinate the effect  of micro-compound fertilizers and humic acid on phosphor availability and upland rice yields on coastal land. This research was conducted from August to December 2021 in Beringin Raya Sub-District Muara Bangka Hulu, Bengkulu City. Soil and plant analysis was carried out in the Soil Science Laboratory, Faculty of Agriculture, Bengkulu University. This research was organized in  Randomized Completely Block Design (RCBD) with 2 factors. The first factor is micro-compound fertilizer which consists of 3 levels, namely 0, 70 and 140 g/ha and the second factor is humic acid which consists of 2 levels, namely 0  and 8 L/ha. Each treatment combination was reploicated 4 times. The results showed that there was no interaction between humic acid and micronutrient fertilizer on the observed variables. The application of humic acid at 8 L/ha  increased phosphor available by 27.55%, the root colonization by 20.65%, the population of microorganisms by 14.77%, the number of productive tillers of 15.72% and the weight of the pithy grain per plant by 31.50% as compared to control. Also, the application of micronutrient fertilizer at 140 g/ha increased the  weight of 1000 seeds, the number of productive tillers, the pithy grains by 7.22, 18.53, and 27.77% respectively as compared control. It is recommended that the upland rice variety can cultivate in coastal land with the application of 140 g/ha micronutrient fertilizer combined with 8 L/ha of humic acid.

Abstract

[PHYSIOLOGICAL RESPONSES AND YIELDS OF FOUR LOCAL GOGO RICE CULTIVARS OF CENTRAL SULAWESI TO DROUGHT STRESS]. Rice is the most important staple food for Indonesians and can be grown in dry land agroecosystems as an upland rice. The research was conducted to study the physiological mechanisms related to drought resistant schemes on four local upland rice cultivars of Central Sulawesi. Field research was carried out using factorial Completely Randomized Block Design (CRBD) with two factors and three blocks as replication. The first factor was four cultivars of upland rice, i.e., Habo, Hiwanggu, Sunggul, and Lambara; while watering intervals of once in one, two, four and eight days was considered as second factor. The observed variables of this experiment were soil moisture, relative water content of leaf, stomatal conductance, concentration of leaf carbon dioxide, transpiration rate, photosynthesis rate, and yield of grain per grove. The collected data were analyzed with regression using independent variables of soil moisture and dependent variables of relative water content on leaf, stomatal conductance, concentration of carbon dioxide on leaf, transpiration rate, photosynthesis rate and yield of grain per grove. The relationship among observed variables was determined using correlation analysis. The results showed that drought resistant upland rice cultivars (Habo and Sunggul) required less optimum soil moisture than those of non-drought resistant cultivars (Hiwanggu and Lambara) to maximize relative water content, stomatal conductance, carbon dioxide, transpiration rate and photosynthesis rate. Soil moisture contributions to maximum yield of grain per grove on Habo, Sunggul, Hiwanggu and Lambara cultivars were 23.41%, 23.00%, 27.14% and 26.67%, respectively.

Abstract

[CHANGES IN SOIL CHEMICAL PROPERTIES AND MUNG BEAN (Vigna radiata L.) YIELD IN INCEPTISOLS, NORTH MORAMO AS AFFECTED BY APPLICATION OF SAGO WASTE COMPOST]. Inceptisols are one of the most widespread soil types in Southeast Sulawesi with an acreage of ​​around 2,280,567 ha (62.07%) and potential for agriculture development. The primary drawback of Inceptisols developed for cultivating mung bean includes a highly acid soil reaction with low soil pH. The polybag experiment was conducted with the objective to determine changes in the chemical properties of the soil after being amended with sago waste compost and its effects on mung bean yield. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Halu Oleo University. This study used a randomized block design consisting of five levels of sago pulp compost (i.e., 0, 100, 200, 300, and 400 g/polybag) with three replications. The results showed that the application of 400 g/polybag of sago pulp compost increased soil pH and organic C by 5.02 and 2.23%, respectively. Increases were also observed in total-N (0.24%), available-P (19.85 ppm), available-K (0.24 me/100g), and CEC (11.99 me/100g). The application of 300 g/polybag of sago pulp compost resulted in the highest number of pods (11.33 pods) and the weight of 100 green bean seeds (9.39 g).
