Published: February 2022

Abstract
Soybean is the main food crop in Indonesia after rice and corn. Soybean is a raw material for several foods which are a good source of fiber for the human body. Soybean productivity in Indonesia is still low at 15.24 Ku/Ha because farmers are still using a monoculture cropping system, which causes plant physiological processes to be not optimal so that growth and yields are low. One of the efforts to increase soybean growth and yield is by the intercropping system. The potential crop for intercropping with soybeans is corn because it has different physiological and morphological characteristics. This study explained the physiological aspects of plant height and number of leaves, leaf area, plant dry weight, and yield. The treatment tested were monoculture soybean and soybean intercropping with various proportions of corn population. The result showed that soybean and corn intercropping produced higher physio-morphology than monoculture soybeans.

Abstract
The upstream watershed area (DAS) has a function as a buffer zone. The Merawu watershed is one of the upstream parts of the Serayu watershed which is dominated by agricultural land. The declining carrying capacity of the Merawu watershed is indicated by the imbalance between supply and demand for resources in the Merawu watershed. For a long time, it can interfere with the function of the soil as life support. The research objectives are: 1) analyzing the carrying capacity of the Merawu watershed through 3 approaches, namely: ecological footprint (land capacity), water capacity, and land protection capacity. The research method used is to compare supply and demand. And 2) Formulating a recovery strategy in the Merawu watershed based on an analysis of the environmental carrying capacity and focusing on increasing the carrying capacity. The results showed that the Merawu watershed has the carrying capacity of the protection function in the overshoot condition, the water carrying capacity in the conditionally-save condition, and the carrying capacity of the land in the overshoot condition. There are five watershed recovery strategies in the upstream, middle and downstream areas to increase carrying capacity.

Abstract
Earthworms play an important role in mixing soil particles with biochar grains, as well as creating biostructures, and the application of seaweed extract to soil affects the microbes within, as well as plant growth. This study, therefore, aims to investigate the effect of mixing soil, teak leaf biochar, as well as seaweed extract on the arbuscularmycorrhizal fungal (AMF) spores within the biostructures formed, and analyze the effect of applying these biostructures to planting media soil on the growth and yield of local upland rice. Before the experiment, extract stock from Sargassum sp. was diluted with water into five separate concentration levels, 0%, 20%, 40%, 60%, and 80%. Subsequently, 20 individual earthworms were released on the soil surface previously mixed with biochar and seaweed extract in a reactor. The planting media used in this study was soil from the cogongrass area with grain sizes below 4 mm, and about 10% (w/w) of the biostructures formed were added to the media in a polybag, then the mixture was transplanted with upland rice seedlings of local variety Sorawolia.According to the results, the treatment containing had the highest total AMF spores. Furthermore, the addition of biostructures significantly affected plant height, leaf number as well as area, and the number of tillers at 42, 42 to 70, and 70 days after application, respectively. Meanwhile, the highest plant dry weight and panicle length were obtained from the treatments containing 80% and 60% extract stock, respectively. However, there was no significant difference in the spikelet number and percentage of filled spikelets between the biostructures. Therefore, the application of both teak leaf biochar and extract of Sargassum sp. was concluded to be able to improve the performance of earthworms (Pheretima sp.) in creating soil biostructures containing AMF spores, for local upland rice development in conditions of poor soil fertility. However, future studies are required to investigate this application’s potential as a source of inoculum for AMF spores or other beneficial microbes, for application at the smallholder farm level.

Abstract
The response of citrus cultivar on soil fertility under different locations has been known prior to its fertilizer application. The aim of this research was to study the effects of different soil fertility on the growth and development of citrus cultivars under two locations. This research was conducted at Langgam Subdistrict, Pelalawan Regency, Province of Riau, Indonesia from February to June 2020. The three-year-old citrus trees of Siam (Tangerine) cv. Pontianak/SP (C. nobilis) and Keprok (Mandarin) cv. Tejakula/KTJ (C. reticulata Blanco) were used in this study. A statistical comparison (Student’s t-test) was used to compare the growth of two citrus cultivars planted into two locations. The nutrient contents in soil and leaves were determined; the growth parameters and leaf pigments were observed and the correlations were analysed. The results showed that status of soil nutrition in two locations ranged low to medium, with pH of 5.1-6.0. At the first location, SP absorbed elements of Ca, Mg, Fe, Zn and Mn 24.1% higher than KTJ. On the other hand, KTJ could absorb the P, K, Na, S and B elements by 24.4% higher than SP. However, at the second location SP is more adaptive on absorbing the elements of N, Na, Mg, S, Zn and B by 26.9% higher than KTJ, while this cultivar could absorb only 10.3% higher of K and Mn. Status value of chlorophyl a and b of citrus cultivar grown in location I was higher. A positive linear relationship has been found between all growth variables with C organic, EC, CEC, Fe, P2O5, K, Ca, pH, and SO4 of soil. The same relation has been found with increasing trunk cross-sectional area (TCA) for growth of plant height and canopy of both cultivars. In general, the growth and development of Siam Pontianak was better than Mandarin Tejakula. The status of soil nutrition and the initial growth performance of each cultivar can be used as a guideline for the application of balanced fertilizers to produce plants that grow optimally.

Published: February 2022

Abstract
Oil palm is a plantation crop that produces palm oil and palm kernel oil which are Indonesia's main source of foreign exchange from the plantation sector. The practice of monoculture cultivation on oil palm plantations grown on various types of soil in Indonesia, has big challenges in the aspect of cultivation, especially pest and disease control. One of the diseases that cause losses in the cultivation of this commodity is dry frond. This disease has been found in oil palm trees in the plantation of PT Bumitama Gunajaya Agro grown on Quartzpsamments and Haplohemists soils. This pathogen causes the rachis and leaves to dry from the tip to the base of the frond. The spread of this disease is thought to be due to contact between infected to healthy fronds. In this study, 6 isolates were obtain from leaves and 7 isolates from infected rachis. Based on the macroscopic and microscopic characteristics of the isolates, one isolate from Sungai Langir Estate belonged to the genus Thielaviopsis sp. However, the postulate koch test showed that the thirteen isolates could not infect and cause symptoms of dry frond disease on the leaves and rachis of the tested oil palm plants.

Published: February 2022

Abstract
A new methodological approach is proposed to identify the effect of changing conditions on the performance of drilling operations in open pit mining. Drilling is presented as a subsystem of the more general system called a “mine”, the stability of which is affected by multiple factors. This paper describes the first stage of implementing the proposed methodological approach to identify the blasthole drilling factors that govern the transitive processes as necessary reactions of the “drilling operations” subsystem when adapting to the changing operating conditions. The revealed main factors which affect the “drilling operations” subsystem stability at the level of blasthole drilling at the pilot site of a mine are presented.
