Abstract
Over the last few decades, steel has seen a sharp increase in utilisation. Non-destructive testing (NDT) methods still face difficulties when attempting to identify corrosion behind coatings. One of these difficulties is the lift-off that complex structures bring. Because of the structure’s obstruction, corrosion goes undetected and can cause catastrophic breakdown. Additionally, lift-off effects lessen the sensitivity. On this paper the effect of coating thickness was measure by using metallic coating at carbon steel and stainless steel plates. The effect of coating thickness being identify based on measurement changes with different layer of coating thickness. From here the absolute and differential probe were used in measuring the lift-off because of coating thickness and the defect value. According on the result show that the Length of the crack at Toe, Root and Heat Affected Zone (HAZ) will reduce from 2.6% until 38.5% for carbon steel and 2.6% until 48.7% for stainless steel when the thickness of coating was increased. It different with Datum measurement where on carbon steel it increases from 0% until 11.5% and stainless steel 0.7% until 6%. Lastly the effect of coating thickness more effecting on defect measurement either carbon steel or stainless steel and artificial intelligent should be apply on each measurement for finding the right data getting in measurement as recommended.
Development of a radiation detector using a silicon photomultiplier and large Ce-doped Gd-Al-Ga-grant scintillator for gamma spectroscopy observations of radioactivation in a linear accelerator

Abstract
In this study, a radiation detector based on a silicon
photomultiplier (SiPM) and large Ce-doped Gd-Al-Ga-grant (Ce:GAGG)
scintillator was developed for the gamma spectroscopy observations
of radioactivation from linear accelerators (LINACs). The
calibration of the detector demonstrated a high energy resolution of
15.89% at 122 keV (gamma-ray emission energy of Co-57), 7.04% at
356 keV (gamma-ray emission energy of 133Ba), 6.17% at
511 keV (gamma-ray emission energy of Na-22), and 5.39% at
662 keV (gamma-ray emission energy of Cs-137). These results
indicate that the detector employing a larger Ce:GAGG scintillator
provides a higher detection efficiency while maintaining superior
energy resolution compared to conventional radiation detectors that
use smaller Ce:GAGG scintillators. Furthermore, the energy spectrum
measurement of the LINAC revealed detection of neutron and gamma
peaks of W-187 and Mn-56, as well as annihilation peaks. Although
the energy resolution of the detector was inferior compared to an
HPGe detector, it was able to measure similar energy
peaks. Therefore, the radiation detector developed in this study,
which is characterized by its low cost, decent energy resolution,
and high detection efficiency, may be useful for obtaining radiation
measurements during the disposal of LINACs.

Published: May 2023

Abstract
Swampland is one of the potential agroecosystems of rice production in Indonesia, but it is classified as marginal in terms of unpredictable inundation, primarily due to global climate change impact. Submergence-resistant variety’s high-yielding and efficient input are one of the efforts to overcome these constraints. The review aims to explore information on the availability and potentiality of immersion-resistant varieties, the efficiency of cultivation technology, and the availability and potentiality of local rice as a source of genes in creating immersion-resistant varieties. The review method is a reference study of different research results. The review results show that five varieties of swampland rice are mainly assembled to withstand immersion in all vegetative phases, namely for six days (Inpara 3) and fourteen days (Inpara 4-5, Inpari 29-30). Based on the Relative Agronomic Efficiency (RAE) parameter, cultivation technology is available. However, information on the research results and its implementation on these five varieties and other high-yielding rice varieties in the swampland is still limited. Sixteen local accessions of inundation tolerance have been identified. Further research is needed on different varieties of immersion resistance, RAE parameters-based cultivation technology, and new immersion-resistant varieties using available local varietal gene donors. This way the availability of effective technology and its dissemination efforts will have the opportunity to be adopted by the stakeholders, thus increasing their productivity and income.

Abstract
Asiaticoside is an active constituent for anti-leprosy, wound healing, increasing vitality, and memory in overcoming dementia. Centella asiatica contains asiaticoside, that is widely used as a medicinal simplicia. Inceptisol Ngipiksari is a type of soil on the southern slopes of Mount Merapi which rich in weathered minerals and nutrients K, Ca, Na and Mg which are necessary for the growth and continuity of Centella asiatica cultivation. The purpose of this study was to determine the effect of SP-36 fertilizer dose and soil moisture conditions on the contents and production of asiaticoside. The experiment used a factorial Completely Randomized Block Design with 3 replications. The factors tested were the dose of SP-36 fertilizer (4 levels: 0, 75, 150 and 225 kg SP-36 ha−1), and soil moisture conditions (2 levels: 50% of field capacity conditions and field capacity conditions). The results showed that the soil CEC significantly positively correlated with asiaticoside contents. The number of leaves, secondary vines, tillers, fresh and dry shoots weight, fresh and dry root weight, available P after fertilization, P absorption by plant, and asiaticoside contents were significantly positively correlated with the asiaticoside production with a moderate to very strong relationship. Watering at field capacity can increase asiaticoside production as 276.6%. The application of SP-36 fertilizer was able to increase asiaticoside contents as 39.1–101.6%. This shows that SP-36 fertilization can increase the asiaticoside content, and control of soil moisture at field capacity can increase the asiaticoside production of Centella asiatica as medicinal simplicia.

Published: May 2023

AbstractThe use of artificial chemical fertilizers that are very intensive and not in accordance with the availability of soil nutrients, has a negative impact on decreasing agricultural soil fertility and vegetable productivity. The aim of this experiment was to obtain an effective and efficient dose of compound fertilizer (Ca and N) for potato plants in Andisol soil type, Lembang. The experiment was carried out at Margahayu Experimental Field of Indonesian Vegetable Research Institute (IVEGRI) (1250 m asl), from June to November 2021. A randomized block design was used with 8 treatments and 4 replications. The treatments consisted of without N fertilizer, standard N single fertilizer, and 6 doses of compound fertilizer (33% Ca and 17% N). The results showed that, in general, CaN compound fertilizers increase the growth of potato plants. The application of compound fertilizer at 75% of N standard (300 kg/ha of CaN fertilizer) was the most effective dose for fertilizing potato plants on Andisol soil type in Lembang. This dose can save the use of N by 25% with a Relative Agronomic Effectiveness (RAE) value of 140%. This study showed that the use of CaN compound fertilizers at a dose of 300 kg/ha can not only reduce fertilizer input into the soil, but also increase potato yields.

Abstract
Granola L. is one of potato variety that is very popular in Indonesia and is currently difficult to replace by other varieties. One of the efforts to maintain the genetic purity of the Granola L. variety can be done through biotechnology technique using molecular markers. This research aimed to obtain molecular markers for the Granola L variety. The selection of molecular markers was carried out at the Molecular Biology Laboratory and screenhouse of Indonesian Vegetable Research Institute (IVEGRI) from March to October 2020. The treatments consisted of DNA of Granola L variety from Source Seed Management Unit (UPBS) - IVEGRI, 8 DNA genotypes/germplasm collections which were assumed to be Granola or has a Granola background (Granola BPBK, GM-05, G2, G8, G-771, G-772, GC21, Papita), and 2 DNA genotypes that do not have Granola background (non-Granola) namely Spudi and Amabil varieties. The molecular markers used in this study were 17 SSR primers (Simple Sequence Repeats) from Indonesian Agricultural Genome Center. The results showed that 11 primers were monomorphic and 6 primers were polymorphic. These polymorphic primers still cannot specifically distinguish between Granola L. and non-Granola L. varieties. There is one primer that can distinguish Granola and non-Granola in terms of the band size formed. Further research is needed to find molecular markers that can distinguish Granola L from varieties/genotypes/germplasm collections that are assumed to be Granola L. or having the Granola L. genetic background.

Abstract
Application of different forms of silicon sources may influence rice production and quality. It is believed that properties of nanosized particles may differ significantly from those of the original bulk material. This study aimed to investigate effects of application of silica nanoparticles extracted from rice husk ash, called nanobiosilica (NBS), on the rice growth, productivity, and milling quality as compared to those of rice husk ash (RHA), sodium silicate solution (SDS), and two control treatments. NBS was produced by the sol-gel method. The five treatments were arranged on a randomized complete block design with four replicates. Application of NBS (20-50nm) and SDS significantly produced the highest stem strength, lodging tolerance, number of productive tillers, grain per-clump, and rice productivity (7.30-7.32t/ha). NBS produced better yield performances than RHA, the initial bulk material. The treatments did not influence brown rice and milled rice yield. However, the highest percentage of head rice was observed following NBS and RHA treatments. The results suggested that production of NBS from RH and its application to paddy field could be a viable strategy for supporting sustainable rice production, producing better quality of milled rice, increasing benefit of rice processors/farmers, and reducing environmental issues of underutilized rice husk.

Abstract
Ciherang is the most extensively planted rice variety in the Indonesia. Ciherang was released as a rice variety in 2000 and successfully replaced IR 64 as the most dominant variety. The wide adoption of Ciherang is because of its acceptable to farmers’ preferences including high yield, resistance to major diseases and good grain quality. Recently, Ciherang become vulnerable to pest and diseases and get low yield due to more occurrence the abiotic stress. The Rice breeding program to develop the Ciherang reborn has been conducted in Indonesian Center for Rice Research. The research aimed to select lines based on yield, morphological performance, and resistant to main pest and diseases for next evaluation of a multilocation yield trial for releasing variety. The materials used were 56 rice genotypes that evaluated yield, agronomic characters, and evaluated to brown planthopper and bacterial left blight. Ten promising lines was selected, derivative from Ciherang or similar ideotype with Ciherang, high yielding, more resistant to main pest and diseases than Ciherang. These promising lines was evaluated in multilocation yield trials for releasing variety.

Published: May 2023

Abstract
Sheath rot disease is one of the critical problems limiting rice production. Fusarium spp. is one of the pathogens that cause sheath rot disease and produce various mycotoxins. The study of mycotoxins detection using specific primers and their association to pathogenicity is important in order to comprehend the types of mycotoxins that may occur in this disease. The objectives of this study are to investigate potential pathogen-related mycotoxins and their relation to pathogenicity. This study included a total of 44 Fusarium spp. isolates from 11 species with five primer pairs of mycotoxins biosynthesis encoding gene. The pathogenicity test was conducted on Ciherang rice variety aged eight-weeks after transplanting. Trichodiene synthase encoding gene only amplified on certain Fusarium bubalinum isolates, while fumonisin biosynthesis encoding gene only amplified on certain F. proliferatum isolates. Beauvericin biosynthesis encoding gene was amplified on F. fujikuroi, F. grosmichelii, F. tanahbumbuense, certain isolates of F. proliferatum, and certain isolates of F. pseudocircinatum. The F. hainanense, F. sulawesiense, F. andiyazi, F. sacchari, several isolates of F. proliferatum, several isolates of F. pseudocircinatum and a species within the F. solani species complex were not amplified on all primer tested. The pathogenicity test results showed that the isolates detected for mycotoxins had no relation with the severity of the disease, the necrosis area in the leaf sheath and the AUDPC. Nonetheless, because mycotoxins have an influence on human health, the findings of this study can be used to enhance pathogen control in order to increase food security in sustainable agriculture.

Abstract
Yellow leaf curl disease caused by pepper yellow leaf curl virus (PepYLCV) and transmitted by the whitefly (Bemisia tabaci), becomes the main problem in major horticultural crops, including chili pepper. The control of the insect vector is crucial to overwhelm the diseases. The experiment was designed to verify the efficacy of integrated vector and virus control focused on barrier crops and healthy seedling techniques on chili pepper to reduce whitefly crowdedness, the prevalence of the virus, and crop yield. This experiment used a randomized block design. The treatments were two kinds of seedlings, with and without seedling cover, combined with four kinds of borders i.e., maize, Sunn–hemp, screen (chiffon), and control (non-border). The result indicated that the use of protected seedlings was able to defend against the attack of B. tabaci and delay virus infection for about 2 weeks. The use of protected seedlings together with barrier crops (maize and sunn-hemp) reduced the number of pests, and PepYLCV damage up to 49.94 – 50.80%, and gave the highest yields. The positive correlation (r) between the population of B. tabaci and disease incidence was 0.925, whereas the correlation between disease incidence and yield crop was negative (r = -0.8886). These results will provide an advance of more valuable and practical methods for safeguarding chili pepper production.

Abstract
Brown planthopper (BPH) Nilaparvata lugens Stall is a major pest of rice that often causes outbreaks in several rice production centers in Indonesia. The use of insecticides is still the choice of farmers to control attacks due to weak mitigation efforts in an area. Continuous use of insecticides can increase the resistance and resurgence of BPH. The purpose of this study was to determine the level of sensitivity of the BPH population to the pimetrozine insecticide. The research was conducted at Assesment and Research Instalation of Agricultural Technology Ungaran, Assesment Institute of Agricultural Technology Central Java, Semarang Regency, Central Java, Indonesia from October 2019 to June 2020. The BPH population was collected from five regions, namely Jaten and Bolong Districts, Sukoharo District, and Bendosari, Mojolaban and Pulokarto Districts, Karanganyar District. The method of sensitivity test of BPH to insecticides was carried out according to the IRAC method number 005. Observations were made on the percentage of BPH mortality. The data was processed using Probit analysis to determine the LC50 value. The LC50 value was used to determine the resistance factor (RF). The results showed that the population of BPH Bolong Karanganyar was the most sensitive to the insecticide pymetrozine with an LC50 value of 13.44 ppm. The populations of BPH Jaten, Bolong, Bendosari, Mojolaban and Pulokarto were not resistant to pymetrozine insecticide due to the level of RF was ≤4. The population of BPH Pulokarto Sukoharjo with an RF value of 2.47 has the potential to become more resistant to the insecticide pymetrozine. It is necessary to periodically monitor the resistance of BPH to pymetrozine insecticides in the Karanganyar and Sukoharjo areas to prevent further resistance development.

Abstract
Inceptisol is one of the soil types covering the Langkat Regency. Unfortunately, the soil has low chemical fertility and is characterized by a small part of macronutrients. To support the maize growth in inceptisol, nitrogen, phosphorus, and potassium are the primary required nutrients. Hence, applying inorganic fertilizer is one of the strategies to solve this issue. This study was conducted at Sei Bingai District, Langkat Regency, from July to November 2021. This study aims to analyze the effect of phosphorus and potassium on the maize growth and production of inceptisol. This study was arranged by Non-Factorial Randomize Complete Block Design with seven treatments and four replications. These treatments are consist of: PK 0 (control), PK 1 (standard fertilization), PK 2 (50 % PK plus dose + 75 % standard fertilization), PK 3 (100 % PK plus dose + 75 % standard fertilization), PK 4 (150 % PK plus dose + 75% standard fertilization), PK 5 (100 % PK plus dose + 50 % standard fertilization), PK 6 (150 % PK plus dose + 50 % standard fertilization). The results show that the PK 5 and PK 6 treatments contribute to the highest maize production by 9.300 kg/ha and the highest Relative Agronomy Effectiveness (RAE) value, 147 %. Fertilization dose of 10 kg ha−1 PK Plus + 50 % standard fertilization is recommended for corn cultivation and is very economically feasible.

Published: May 2023

Abstract
Soybean productivity in Indonesia was greatly affected by low soil fertility due to the excessive use of chemical fertilizers. Applying organic fertilizer or compost such as palm bagasse could be a potential source of organic matter to improve soil fertility and crop productivity. An effective compost should be rich in fiber and high C/N ratio. Therefore, compost is recommended to be mixed with other low C/N ratio materials to accelerate the composting and increase N content. This study was aimed to determine the mixture ratio of palm bagasse compost (PBC) with other materials, such as Azolla, Gliricidia leaves, tofu dreg waste. This study was conducted in Completely Randomized Block Design with two factors. The first factor was type of mixing ingredients such as Azolla, Gliricidia leaves, tofu dreg waste. The second factor was the dose (%) of PBC in combination with Urea (%), namely 0, 25, 50, 75, 100%. Each treatment was repeated in blocks. Results showed that the mixture of PBC with all organic N sources was promising to substitute Urea. Moreover, application of 100% PBC exhibited the highest soybean yield, suggesting that PBC could provide sufficient nutrients for soybean growth. This present study emphasized the potential of soybean production optimization with low dependence on chemical fertilizers, thus highlighting the potency of more sustainable soybean cultivation using organic fertilizer.
