Authors: Fu Cheng fang , Lu Mingxu , Zhao Bo 
Published: May 2023

Abstract
The performance stability of the system can be improved by incorporating a solar chimney with a phase-change material (PCM). It is recommended that instead of using the traditional multi-curved trough air collectors for solar greenhouses, a solar phase change thermal storage wall construction system with vertical air channels be employed. Solar thermal utilization of the rear wall. In order to verify feasibility of the construction system, a multi-curved trough air collector test system for solar greenhouse and a phase-change heat storage wall test system with vertical air channels were built respectively. The air velocity in the heater, the air flow parameters (air velocity, air channel spacing, air flow direction) in the sensible heat storage wall layer in the solar greenhouse, etc. The study’s findings indicate that the collector performs at its peak level of total heat absorption when its air velocity is between 1.4 and 1.8 m/s, and that heat absorption rises as solar radiation intensity rises. The suggested system design orientation offers an efficient way to raise the thermal performance of the system with the least amount of work and expense for practical applications.

Abstract
Breakwaters are the structures constructed in the coastal areas to maintain calm inside the port or prevent beach erosion. Semi-circular Breakwater (SCB) is an innovative type of Breakwater made of hollow caisson on a base slab with or without perforations. In this study, the wave overtopping discharge parameter of an SCB is estimated using Artificial Neural Network and Random Forest. The data is collected and used in the current research from an experimental investigation conducted in the Wave Mechanics Laboratory of the Department of Water Resources and Ocean Engineering (WROE), NITK Surathkal. Using this experimental data, the ANN and Random Forest models are developed for the prediction of the wave overtopping discharge parameter of an SCB. The performance of the models is evaluated using different statistical parameters. Data with and without normalisation are used separately to check the effect of normalisation in the prediction of wave overtopping discharge parameter using ANN and Random Forest. From the results, it is found that ANN gives better results when the data is normalised. The performance of Random Forest is independent of the data normalisation.

Published: May 2023

Abstract
The phenomenal strides in the modifications and the use of supplementary cementitious materials in conjunction with superplasticizers and discrete fiber distributions in concrete made it possible to arrive at the structural material termed as “ultra-high performance concretes” (UHPC) or its extension “ultra-high performance fiber reinforced concretes” (UHPFRC). Its development heralded a new era, opening new vistas in structural configurations and forms that could be a serious contender to structural steel constructions. Primarily, the chemistry and physics of concrete constituents and mixture design philosophy have not changed much, though the intricacies that are often neglected were effectively corrected from time to time. The use of materials ranging from the conventional to nanoparticles that could exhibit superior pozzolanic activity along with microfibers resulted in strengths well beyond 200 MPa. This opens up several avenues in structural configurations that are of high strength and durability. However, this isn’t a stipulation of replacing the present-day concrete in all structures with UHPC, but the key is to modulate the structural configurations to suit the needs of the particular application for ensuring sustainability in consonance with the capabilities of UHPC. The paper attempts to look at the possible avenues for such options in materials and structural forms to effectively assure sustainable construction alternates.

Published: May 2023

Abstract
Filler’s presence in hot-mix asphalt (HMA) is even though minimal but they do affect its durability characteristics. Many natural and waste materials in the form of fillers have been studied for their effectiveness on HMA mix design and performance characteristics. However, in practice, stone dust (SD) is the preferred filler due to its abundance, ease of availability, and cost-effectiveness. Thus, the major objective of this study was to investigate the effect of locally available materials: stone dust (SD)- natural, hydrated lime (HL) – processed, rice-husk ash (RHA) and fly-ash (FHA)-waste materials on HMA properties based on the factors such as availability, field utilization, cost, and sustainability, while at the same time identify the anomalies of those selected fillers on HMA mix if any. A viscosity grade (VG-30) binder was selected and checked for its fundamental consistency characteristics set forth in Indian standards. In this study, aggregate gradation structure specified as bituminous concrete grading 1 (BC1) in India was designed for the preparation and evaluation of four HMA mixes: (a) BC1 with SD (BC1-SD), (b) BC1 with RHA (BC1-RHA), (c) BC1 with FA (BC1-FA), and d) BC1 with HL (BC1-HL). Fillers: RHA, FA, and HL were studied for their physico-chemical properties. The most recommended filler dosage of 4% by weight of mix was selected and kept uniform for the various BC1 mixes. Marshall method of mix design was performed to identify the optimum asphalt content (OAC) of four different BC1 mixes. The test results of methylene blue value (MBV), german filler value (GFV), and fineness modulus (FM) indicated that RHA includes more micron-to-nano sized particles than the other two fillers (HL and FA). The scanning electron microscope coupled with energy dispersive X-ray results showed that the RHA and FA exhibited similar chemical composition, while HL was identified to be a calcium-based compound. The BC1-RHA mix resulted in non-cohesive mix for the binder content ranging from 4.5 to 6.5%. Additionally, for the binder contents in the range of 7 to 9% the BC1-RHA compacted samples failed to yield air voids of 4% required to arrive at the OAC. The BC1- FA mix showed the highest Marshall stability (26.97 KN) followed by BC1-HL (23.97 kN), and BC1-SD (17.9 kN). Also, retained stability test results of all the three different mixes were in close proximity to each other indicative of the affinity of the fillers to asphalt. The resistance to moisture susceptibility results indicated that HL is the better anti-stripping element followed by FA, and SD. Among the three different filler-based BC1 mixes, BC1-HL mix was adjudged as an effective moisture resistant mix followed by BC1-FA, and BC1-SD. However, a single filler that not only tends to improve the various performance parameters of the mix but be available in abundance and cost-effective is yet to be explored.

Abstract
The agricultural sector must receive serious attention today since it faces many challenges such as the small size of land ownership and the low interest of the younger generation for doing this business. Various efforts have been made, including the agricultural technology park program and other programs for increasing production and farmer welfare. All those agricultural programs need to be supported by technology and model to get properly development. This study aims to increase the productivity and income of farmers in the agricultural development area. The research activities include potentials and problems of farm identification by a Forum Group Discussion and research implementation using a factorial randomized completely block design with four new high yield varieties and one existing variety. The results showed that farmers were very enthusiastic and responsive to the use of new high yield varieties which combined with Jajar Legowo Super technology. The highest yields in the first and second planting season were consistently reached by Inpari 30 variety. It was carried out both in Batui and South Batui District and there was an increase in production around 1.7-2 t/ha. Crop yields and farmers’ incomes have increased. The guidance and assistance for farmer groups has not shown best results, however, collaboration between the breeder group and the off taker (PT Pertani) has been formed, while the development of premium rice has not been optimally implemented due to the COVID-19 pandemic.

Abstract
The production of shallots has been decreasing, one of the factors causing it is soil degradation that caused by the continuously use of chemicals. Thus damaging the soil and killing natural enemies. Soil improvement can be done by adding organic material, minerals, and optimizing the function of biological agents. Trichoderma sp is one of the biological agents that has the ability to degrade soil. This study aimed to determine the effect of Trichoderma form and different application methods on the growth and yield of shallots. The location of the research was in Maku village, Sigi district, Central Sulawesi, from November 2020 to January 2021. The research method used a separate plot design with four replications, where the main plot was the form of Trichoderma sp. (T), which consists of three levels, namely, T1 = liquid (60 ml/bed) and T2 = solid (12 g/bed). The size of the bed is 3 m x 1 m while the sub-plot was the application (C), which consists of three levels, namely C0 = without giving; C1 = bulb straight to the ground; C2 = mix with manure. The results showed that the treatment of Trichoderma sp has a significant effect on plant height and number of leaves, but was not significantly different in way of application. While the interaction of the two treatments have a significant effect on the performance parameters. However, in the yield component, the treatment form and way of application did not show a significant difference. Overall, the best treatment combination was Trichoderma sp in solid form mixed with manure.

Published: May 2023

Abstract
An effort to solve sex-determining problems in nutmeg cultivation is using shoot grafted seeds of known sex parental tree through epicotyl grafting. However, constraint in nutmeg grafting has a relatively high grafted shoot mortality rate due to suboptimal microclimates. Therefore, the study aimed to increase grafted-nutmeg seeds’ viability and plant vigor in the field through micro-clipping and microclimate optimization. The experiment was arranged in a Randomized Block Design, factorial pattern, repeated three times. The first factor was the origin of the scion (Bogor and South Lampung), the second factor was the way of seeds hooding (individual plastic hood; mass hood; individual + mass hood), and the third factor was watering (without fogging and fogging). The results showed that the highest success rate of grafting before separation was obtained using scions from Bogor, which were covered massively without being fogged (85.71%) and being fogged (82.74%). Further, the success rate of grafting after separation was obtained using scion from Bogor, which were covered up massively without being fogged (83.33%) and fogged (79.76%). Therefore, epicotyl grafting in nutmeg can be massively covered either without fogging or fogging. This circumstance implied that epicotyl grafting can increase the availability of nutmeg seeds.

Published: May 2023

Abstract
The use of rootstocks provides choices to growers to increase fruit quality and yield, obtain high-density planting, avoid juvenility, and control tree size. The choice of rootstock for a citrus orchard was an important consideration. The aim of the study was to evaluate the effects of citrus rootstocks on leaf mineral composition and leaf physiology of the citrus commercial cultivars (‘Pontianak’ tangerine, ‘Pamindo’ pamelo and ‘Montaji’ lemon). For this purpose, the citrus commercial cultivars were budded onto Japansche citroen (JC) and Citrumelo rootstocks and then leaf mineral composition (total nitrogen, phosphor and kalium concentration) and leaf physiology (chlorophyll index, respiration rate, stomatal conductance and photosynthetic rate) of each scion were measured. Results showed that rootstock type had different influence on leaf mineral composition and leaf physiology in leaf of each scion. For total nitrogen, total kalium and stomatal conductance variables, rootstocks had no effect. For total phosphor variable, JC rootstock induced higher value than Citrumelo in all scion. For chlorophyll Index variable, Citrumelo induced higher value on ‘Pamindo’ and lower value on ‘Montaji’ than JC but had no effect on ‘Pontianak’ tangerine. For respiration rate and photosynthetic rate variable, Citrumelo induced higher value than JC in ‘Pamindo’ but had no effect on ‘Pontianak’ tangerine and ‘Montaji’. Therefore, ‘Pamindo’ was better to be budded on Citrumelo, ‘Montaji’ and ‘Pontianak’ tangerine were better to be budded on JC.

Abstract
Liberika Tungkal Komposit (Libtukom) coffee is a specific Liberica coffee in the peatlands of Tanjung Jabung Barat Regency, Jambi. The main pest problem in Libtukom coffee is Hypothenemus hampei (Coffee Berry Borer/CBB). This study aims to control H. hampei on Libtukom coffee using a trap with pheromone and technical culture. The study consists of four treatments: technical culture, only traps, technical culture + traps, and without treatment (as control). The traps are made of plastic and the attractant used is Hypotan 50 SL. Traps with attractants were installed at a height of 1.5 m from the ground as much as 24 traps/ha. The technical culture has been carried out by pruning, sanitizing, and “lelesan”. The number of trapped insects is calculated monthly until the end of the study. The intensity of fruit attacks was observed at the beginning and end of the study. Data were analyzed descriptively and the analysis of variance. The results showed that the intensity of H. hampei attack on Libtukom coffee decreased at the end of the study in the treatment and was different without treatment. The number of trapped H. hampei insects decreased at the end of the study. H. hampei control treatment using trap technology and technical culture or a combination can reduce the intensity of H. hampei attacks and the number of H. hampei trapped. The use of traps and technical culture can be applied while supporting environmentally friendly agriculture.

Abstract
Huanglongbing (HLB) disease, causes a 60-95% decline in Indonesia citrus production in almost all production centers. The use of suitable citrus interstocks can increase fruit production and quality, improve compatibility, and can also increase tolerance to HLB with tolerant interstocks. Potential interstock, providing an alternative for citrus farmers to be able to save their plants from the destruction of HLB. The purpose of this study was to determine the effect of several interstocks in inhibiting the development of HLB disease and the growth of citrus plants. Eight interstock combination treatments (JC, JC+Rough lemon, JC+Carrizo citrange, JC+citrumelo, JC+Poncirus trifoliata, JC+Volkamer lemon, JC+Troyer citrange and JC+ Kanci kumquat) on 3 commercial citrus varieties (C. reticulata var. Batu 55, C. nobilis var. Pontianak and C. aurantifolia var. Nimas Agrihorti). The combination of interstock affects plant tolerance to HLB. In the three upper limit varieties tested, the mildest symptoms of HLB and the healthiest was found in the combination of interstock JC+P.trifoliata, and Candidatus Liberibacter asiaticus were detected after inoculation using conventional PCR amplification in the second test. Based on the PCR index and the severity of the symptoms, the combination of interstock JC+P. trifoliata was classified as mild severity and the healthiest against CLas infection in the 3 scion varieties tested (C. reticulata var. Batu 55, C. nobilis var. Pontianak and C. aurantifolia var. Nimas Agrihorti). Vegetative growth was found to be varied, and almost all of them could grow well except shoot growth which was stagnant at 5-6 months after inoculation.

Published: May 2023

Abstract
Soil-borne diseases in shallots are the main diseases that can cause weight loss, especially for seeds. One of the biological agents that can control the disease is Trichoderma sp. So far, the use of Trichoderma often does not seem effective because the application time is not right. Trichoderma already exists and grows outside and inside plant tissues. This is due to the nature and character of Trichoderma for its antagonistic fungus that competent to colonize the rhizosphere quickly and protect roots from pathogen attack. This study aims to determine the interaction between the application time of Trichoderma sp and varieties on growth and disease development for seed production. The research was carried out at the Margahayu Experimental Garden, Institute Vegetable Research Indonesian (1,250 m.asl), from September to December 2021. The experiment used was a factorial randomized block with two factors and three replications. The first factor is the time of application of Trichoderma (without Trichoderma, before planting, before planting + 2 weeks after planting, and before planting + 2, 4 weeks after planting). The second factor is several varieties of shallots (Violetta, Ambassador, Maja Cipanas, Bima and Trisula). The results showed that there was no interaction between application time and variety on growth, disease attack, and yield of shallot bulbs for seed. However, application time and varieties affected the intensity of the disease of Stemphylium vesicarium and Peronospora destructor. Maja Cipanas showed the highest plant growth (plant height, number of leaves and number of tillers) with dry weight, weight of one month of storage and weight of two months of storage per clump each of 60.19 g; 50.27 g and 39.49 g.

Published: May 2023

Abstract
Sweet potato are potential to be utilized as replacer or substitution agent for rice for Indonesian. It provides some good nutrients to maintain healthy degree. It has a high energy content, protein, fat, and a considerable dietary fiber. Four of sweet potato varieties (i.e. Beta 1, Beta 2, Antin 2, Antin 3) contain bioactive compounds such as anthocyanin and beta-carotene. Beta 1 sweet potato had more beta carotene (13.01±1.73 mg/100g) than Beta 2 (5.96±0.44 mg/100g), while Antin 2 had less anthocyanin (32.18±0.01mg/100g) than Antin 3 (35.24±0.1 mg/100g). Nevertheless, Antin 2 contained highest protein (0.81±0.02%) among others. Moreover, Antin 2 and Antin 3 contained higher calories and dietary fiber compared to Beta 1. The lower content of these compounds in Beta variety might be attributed to the higher moisture content of Beta 1 (80.11±0.14%) and Beta 2 (77.40±0.45%), while the moisture content of Antin 2 and Antin 3 were 71.40±0.08% and 70.25±0.25%, respectively. In terms of sweet potato flour, Beta 1 had also more beta carotene (29.41±0.06 mg/100g) than Beta 2 (27.26±0.13 mg/100g), and Antin 3 contained more anthocyanin (47.66±0.05 mg/100g) than Antin 2 (29.04±0.01mg/100g). As for food product, macaroni had been made from flour and pasta of sweet potato. The sensory evaluation demonstrated that the products were well-accepted by the panelists in terms of color, flavor, taste, texture, and overall acceptability, indicating that sweet potato have a potential as food raw material and further utilization to support sustainable agriculture.
