[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%).
[腐殖质复合肥在改善土壤质量和促进辣椒生长中的应用]。辣椒(Capsicum Annum)是一种对印尼经济做出贡献的战略商品。由于辣椒生产的不稳定性,辣椒价格的波动受土壤肥力下降等多种因素的影响。土壤改良剂有助于提高土壤肥力。研究了在辣椒栽培中施用腐殖质化合物对提高土壤肥力、促进辣椒生长和产量的影响。该研究于2021年2月至8月在西爪哇Cianjur的IPB Pasir Sarongge试验场进行。研究采用完全随机分组设计(CRGD),单因素,腐殖质化合物溶液浓度分别为0、2.5、5、7.5、10和12.5 mL/L,每个水平重复4次。方差分析后,采用Duncan’s Multiple Range Test (DMRT)对数据的均值进行分离。结果表明,施用腐殖质复合肥料可提高土壤阳离子交换容量(CEC)值,降低钾淋失率,提高除单株产量外的所有生长和产量性状,提高土壤肥力,促进辣椒生长和产量。施用12.5 mL/L腐殖质化合物可提高CEC,使钾浸出率降至0%,提高株高(37.40%)、枝数(56.72%)和果数(57.81%)。施用10 mL/L的腐殖质化合物可提高10果重(30.78%)、单株产量(27.56%)、单田产量和每公顷预测产量(47.58%)。

[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.

[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.

[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.

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.

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.

[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.

[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.
