Abstract

[THE EFFECT OF LIGHT EMITTING DIODE (LED) IRRADIATION DURATION ON THE GROWTH OF SUNFLOWER (Helianthus annuus L.) MICROGREENS PLANT ON VARIOUS PLANTING MEDIA]. The conversion of agricultural land into residential and office buildings causes a decrease in agricultural land every year so the development of indoor plant cultivation with the concept of urban farming, such as microgreens. Microgreens are plants in the period after germination, usually between 7-14 days. Microgreens have a nutrient content of at least 40 times higher than when they are fully grown. Sunflower plants are one of the plants that have been developed as microgreens. Sunflower (Helianthus annuus L.) is an introduced plant from America. This flower is bright yellow with a large flower head with a diameter of up to 30 cm. LED light is used to help the plant growth process that is carried out indoors. This research was conducted indoors is located in Bratang Wetan 1 No. 19c, Wonokromo, Surabaya from March 2021 to May 2021. The method used in this research is a Completely Randomized Design (CRD) system consisting of 2 factors with 3 replications. The first factor is the length of irradiation which consists of 4 levels of treatment and the second factor is the type of planting media which consists of 3 levels of treatment. The results showed that the combination of 16 hours irradiation time with soil planting medium was able to increase the growth of Sunflower microgreens plants on the variables of cotyledon width, wet weight, dry weight, and chlorophyll test.

Abstract

[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe  and the quality of the  produced fruit when  the application were made only at planting and 23 days after planting.

Abstract

[PHOSPHOROUS AVAILABILITY, ITS UPTAKE AND YIELD OF SWEET CORN UNDER THE APPLICATION OF UREA AND PK FERTILIZERS IN JATINANGOR INCEPTISOLS]. Maize is one of the staple foods cultivated in Indonesia. Low soil fertility causes the low production of maize. Sweet corn requires sufficient nutrients to grow and produce optimally. The application of a combination of Urea fertilizers and PK on sweet corn plants is expected to increase the availability of nutrients and sweet corn crop production. The objective of this study was to determine the effect of Urea fertilizer and PK application on available P, P uptake, and yield of sweet corn (Zea mays saccharata Sturt) on Jatinangor Inceptisols. This research used the Randomized Block Design (RBD) experiment model, consisting of 9 treatments of 1 control treatment (without treatment), 1 standard recommendation of N, P, K fertilizer treatment, and 7 treatments combination of Urea fertilizer and PK. Each treatment was repeated three times. The results revealed that available-P, P uptake, and yield of sweet corn on Jatinangor Inceptisols were affected by the combination of Urea fertilizer and PK. The combination of 300 kg/ha of urea with 215 kg/ha of PK fertilizer increased the available P value until 23,78 ppm, P uptake (0,67 %), and fresh weight of the corncobs (480,27 g plant-1) on Jatinangor Inceptisols.

Abstract

[GROWTH AND PRODUCTIVITY OF THE COMPANION CROP SYSTEM OF SWEET POTATO AND ODOT GRASS AT DIFFERENT SPACINGS]. Odot grass cultivation still has a fairly wide space between the clumps of plants. The companion crop systems with sweet potato plants are an alternative to the use this space. The research was carried out from April 2021 to September 2021 in Kalongan Village, East Ungaran District, Semarang Regency, Central Java Province. The study was conducted in completely randomized block design (CRBD) with 2 factors and 3 replications. The first factor is spacing of the odot grasses with 2 levels, namely 90 cm x 60 cm and 90 cm x 45 cm.  The second factor is spacing of sweet potato with 4 levels, namely 90 cm x 30 cm, 90 x 40 cm, 90 cm x 50 cm, dan 90 cm x 60 cm. The results of statistical analysis showed that there was no significant effect of the spacing between odot grass and sweet potato on the growth and production. However, the effect of the distance between the grass hoppers was significant (P<0.05) on the variable of the tillers and the number of sweet potato branches. The average value results showed that the number of tillers and the number of sweet potato branches between the spacing of the grasshoppers 90 cm x 60 cm was significantly higher than 90 cm x 45 cm. Odot grass can be planted together with sweet potatoes with a spacing of 90 cm between rows, 60 cm in a row of sweet potatoes, and 60 cm in a row of sweet potatoes.

Abstract

Macrotermes gilvus (subterranean termite) can play dual roles as decomposers of natural wood and pest in plantations and urban area. The damages caused by termites in the urban area reaches 35% and in the wood industry can reach 40%. Nowadays, termite control is still carried out by the application of synthetic termiticide. In termites’ case, environmental pollution issue is more important than the resistance of termite to termiticide, so it’s necessary to find alternative termiticide from natural materials. This study examined the potential of clove essential oils to control M. gilvus with two methods. The test methods were oil residue on filter paper and soil in a glass tube H. Clove essential oil on filter paper was applied and dried for one minute, after that put in the petri dish. For soil treatment, the soil was soaked with clove essential oil for one hour and dried for one day, after that the soil treatment put into the bridge tube. Each method was infested by 50 termites with ratio 90% workers and 10% soldiers. Termite mortality on treated filter paper was observed after 72 hours, and on treated soil were observed daily until 7 days. The result showed that clove essential oils caused mortality of M. gilvus more than 90% after consumed and contacted on treated filter paper and contacted on treated soil with concentration 0.80% and 1.20%, respectively. Based on the results, clove essential oil has the potential to be developed and can be used as an alternative against termites, that was environmentally friendly.

Abstract

[EFFECT OF LEAF WASTE PROPORTION AND TYPES OF LOCAL MIKROORGANISM ON THE QUALITY OF BOKASHI]. The purpose of this study was to get a combination of the treatment of the leaf waste proportion and local microorganism (MOL) type to the quality of bokashi. The use of specific MOL as a bioactivator is expected to produce a good bokashi. The production of bokashi was conducted at the Garbage Collection Center of Syiah Kuala University, Banda Aceh, Indonesia. The experimental design was a completely randomized design (CRD) with 2 factors including the proportion of leaves (D) and the type of MOL (M). The first factor consisted of two levels (50% and 70% leaf) and the second factor consisted of 4 levels (rice MOL, soil MOL, bokashi MOL, and leaf waste MOL). The quality of bokashi was measured based on the total cell counts of microbes, pH, C/N ratio, descriptive test (texture, aroma, and colour), and plant growth tests on corn. The results showed that all bokashi have complied with SNI 19-7030- 2004. The best bokasi was obtained from the combination between 50% leaf waste proportion and MOL type of rice. This bokashi had a total microbes of 4.1 x 108 CFU/g, pH value of 7.4, C/N ratio of 10.2, with organoleptic characteristics of loose texture and slightly moisture, slightly soil-scented, blackish color and the hight of test plant of 61 cm. The main advantage of this bokashi compared to others was in the highest number of microbes total and the best texture.

Abstract

[RESPONSE OF THE NUTRITION LEVELS OF SUGARCANE IN THREE ORDERS OF SOIL DUE TO SUGARCANE MONOCULTURE CULTIVATION]. Monoculture cultivation will have an influence not only on soil conditions but also on plant growth, nutrient levels in plant tissues, and yields. The purpose of this study was (1)  to determine the effect of monoculture sugarcane cultivation on nutrient levels of the roots, stalks, and leaves of sugarcane plants, (2) to determine the relationship between nutrient levels in sugarcane tissue and sugarcane productivity, and yield in three different soil orders. This research had two factors, namely soil order (Entisol, Inceptisol, and Vertisol) and sugarcane monoculture period (1–10, 11–20, and 21–30 years). The sugar cane used was the ratoon of two sugarcane. Parameters observed included nutrient levels of N, P, K, B, and Zn in roots, stalks, and leaves of sugarcane, and productivity of plants. Data analysis was performed with ANOVA at 5% level and regression correlation analysis. The results showed that the levels of N (leaves, stalks, and roots), levels of P (leaves, stalks, and roots), levels of leaf K, levels of B (leaves and roots), and level of Zn of sugarcane roots were influenced by the interaction between soil order and sugarcane monoculture period. Zn and K levels in sugarcane leaves had a strong and significant correlation with sugarcane productivity (r=0.778* and r=0.699*), while sugarcane yields had a strong and significant correlation with N content of root (r=0.752*). This result indicates that the soil order and the mass of sugarcane monoculture have an effect on the nutrient content in the plant and this nutrient content affects the productivity and yield. The availability of macro and micronutrients needs to be considered in monoculture sugarcane planting techniques to obtain optimal and sustainable sugarcane yields.
