Abstract
Fishery is an agricultural sub-sector that plays a very important role in the development of the national economy. Fishery resources in Indonesia are very diverse and have the potential that include fish farming. Fish farming aims to produce higher biomass compared to natural fishing. Aquaponics is a cultivation technology that combines the maintenance of fish and plants that are more environmentally friendly and conserves water use. Aquaponics can reduce the accumulation of ammonia, nitrate and nitrite by fish feed residues and fish metabolism with plants and biofilter media to absorb these compounds. Tests were carried out with two installations with different components, namely bioball and activated charcoal (1:1) and control with only bioball components. Testing the effectiveness of the biofilter component was carried out by conducting research designs, preparing tools and materials, cultivation processes, observing and collecting data on red lettuce plant growth, red lettuce plant biomass productivity, tilapia growth, water quality, environmental conditions and data processing and analysis. It was found that the effect of adding activated charcoal biofilter media on the growth of leaf number and chlorophyll content was different, with better average results in activated charcoal installations (1:1), but lower growth in plant height, leaf width, and leaf area (p< 0.05). The growth of leaf area and chlorophyll content affected the treatment position as indicated by the best leaf area at position 8, while the best chlorophyll content was in treatment 2. The addition of activated charcoal biofilter media to dry weight was significantly different (p<0.05) better in the activated charcoal installation compared to the control installation, but with a lower Shoot-Root Ratio. Activated charcoal installation (1:1) also shows better average fish growth with more fish survival and better water quality maintenance.

Published: August 2024

Abstract
Biomass is a promising renewable energy source with great potential. Gasification converts biomass into economically viable energy. Identifying, developing, and optimizing biomass gasification technology requires mathematical models. This article critically evaluates gasification modelling. We investigated thermodynamic equilibrium, kinetics, computational fluid dynamics (CFD), and artificial neural network (ANN) models. This examination will evaluate the advantages and disadvantages of the four models. The assessment results should enable the building of models for bigger reactors, improving gasification. Developing reaction equilibrium constant correction factors makes the thermodynamic equilibrium model better for integrated systems analysis. Future kinetic model development will include simulation tools to build the reactor. The CFD model’s main advantage is its ability to scale up the gasification reactor for better syngas. 3-D CFD models model particle size and feed location, making model construction challenging. The ANN model, despite its excellent predictions, faces limitations due to its reliance on input. This limitation can make ANN model development difficult.

Abstract
Oil palm plays a crucial role in Indonesia’s economy through the increased production and export of oil palm. However, managing and predicting productivity in expanding oil palm plantations presents significant challenges. Current estimation methods are resource-intensive and time-consuming. This study advocates the application of remote sensing techniques, particularly through Google Earth Engine and Landsat 8 satellite imagery, for efficient oil palm productivity estimation. Using a multilinear regression model that integrates the Normalized Difference Vegetation Index (NDVI) and rainfall data from the CHIRPS dataset, historical productivity data is also incorporated using the Holt-Winter exponential smoothing approach. The research aims to enhance oil palm plantation management by harnessing remote sensing technology and weather data analysis. The research results revealed that multilinear regression for the universal model with annual data accumulation using the 12-month shifting rainfall dataset achieves an R2 of 0.855, RMSE of 14,283 tons/ha, and MAPE of 0.975% and the AK12_M3 was the best combination to build a model for each block Meanwhile, the Holt-Winter method for universal mode as well as each block model, using a 4-month seasonal approach produces the best results. With an R2 of 0.83, RMSE of 6,256 tons/ha, and MAPE of 7.501%.

Published: August 2024

Abstract
Chili plants (Capsicum annuum L.) are a high-value horticultural commodity but are very susceptible to disease. Therefore, early detection of chili disease is essential to minimize the potential loss in chili farming. This research aims to develop a prototype for early detection of chili diseases before they become apparent to the human eye. In response to pathogens, chili plants produce substances that actively absorb and reflect ultraviolet light, while near-infrared images can reveal leaf cell structure damage. By considering these plant defense systems, the prototype system, developed with a closed growth chamber, focuses on capturing NIR and NUV images to detect plant diseases. It uses light reflectance in the near-ultraviolet and near-infrared spectrum as input for detecting diseases, coupled with image and pattern analysis for plants affected by viruses and fungi. The primary method of image analysis was texture analysis of NIR and NUV images, specifically image entropy analysis. The system was tested on plants with virus infection (Gemini virus), fungal infection (anthracnose), and under normal conditions. The results showed distinct differences in the image entropy values between virus-infected, fungal-infected, and non-infected leaves, especially from NUV images. This indicates that the system effectively utilizes NIR and NUV imaging to detect diseases, with texture and image entropy analysis serving as reliable metrics. Notably, the system is more effective at early detection of fungal infections (such as anthracnose) than virus infections (such as Gemini virus), with NUV imaging proving more effective than NIR for this purpose.

Abstract
The productivity of Arabica coffee at Andisols in West Java is still relatively low. Andisols are soils with a high P retention capacity. One of the inputs to solve the problem is the application of phosphate-solubilizing microbes. This study aims to evaluate the efficacy of biofertilizers in increasing the productivity of Arabica coffee in Andisols. The study used a randomized block design by the 10 treatments and 3 replications. Treatments consisted of control, solid form B1/microbial consortium 1 in zeolite+compost (30, 60, 90 g/tree), liquid form B2/microbial consortium 2 in PDB+molasses (30, 60, 90 ml/tree), and solid form B3/microbial consortium 2 in compost+biochar (30, 60, 90 g/tree). Microbial consortium 1 consisted of Rhodococcus qingshengii, Burkholderia ambifaria, and Aspergillus niger, while microbial consortium 2 consisted of Burkholderia cepacia, Pseudomonas migulae, Delftia lacustris, and Aspergillus sp. The results showed that formulas B1, B2, and B3 at a dose of 30 g or ml/tree significantly increase fruits weight and green coffee bean production, with an increase in green coffee bean production of 64, 62, and 55% respectively from the control. The three biofertilizer formulas have the potential to be used in Arabica coffee cultivation in Andisols.

Abstract
Parasitic nematodes that cause yield loss up to 32% on black pepper are Radopholus similis and Meloidogyne incognita. Continued application of chemical pesticides causes environmental damage and health issues. Organic fertilizers and biological agents can reduce infections, increase plant resistance, and improve soil fertility. The study aims to study the influence of fertilizer and biological control applications on parasitic nematodes and black pepper production. The research was conducted in a black pepper field in the Tanggamus district, Lampung province, Indonesia, using a Block Randomized Design with 5 treatments and 6 replications. The treatments were organic+inorganic fertilizer, organic+inorganic+biofertilizer, organic+inorganic fertilizer+biological agents, organic+ inorganic+biofertilizer+biological agent, and control (farmers technology). Organic and biofertilizers applied in the early rainy season at 25 g/tree and 3 kg/tree, then the biological agent was a month after at 100 ml/tree. The result showed inorganic and organic fertilizers, biofertilizers, and biological agents suppress the population of Meloidogyne sp. in the roots and soils at 53,90% and 65,88%, respectively. While in productivity, the longest vines were 9,27 cm, the most vines were 8,53 vines and the heaviest peppercorn was 15,97 g. These values were significantly different from the control at 7,8 cm, 4,3 vines, and 8,94 g, respectively.

Published: August 2024

Abstract
Hypersonic flight presents several difficulties linked to the important viscous dissipation of kinetic energy on the surface of a vehicle which causes the need for relevant Thermal Protection Systems, reduces communication efficiency due to air ionization and creates an important pressure load due to the stagnation point on the fuselage. Those effects are enlarged by the presence of a shock wave with its strength growing in the case of a blunt body-shaped vehicle. The aim of this work is to study the effectiveness of the static device called “Aerospike” to reduce the effects induced by the hypersonic flight of a blunt body, in particular with respect to the average surface temperature, the pressure load and drag coefficient. After having studied a base case, an optimization process to define an optimal shape both for the aerospike and the aerodisk are presented.
A convergence study simulating regular waves using the k-ω SST turbulence model in OpenFOAM®
Authors: Xu Xihang , Salauddin Md , Keenahan Jennifer 
Published: August 2024

Abstract
OpenFOAM® has been widely used in coastal engineering to visualise and analyse wave-structure interaction and evaluate the effectiveness of innovative coastal protection structures. To study the influence of an eco-retrofitted seawall on the wave overtopping process, a 2D numerical wave tank with a k-ω SST turbulence model is developed to recreate previously completed experiments. Results of wave structure interactions at a plain vertical seawall subjected to regular waves using OpenFOAM® are presented, considering various configurations of time steps and grid resolutions. Both deep water (near the wave maker) and shallow water (near the structure) wave structure interactions are analysed. Results indicate that a finer mesh density is required in shallow water regions compared with deep water regions due to the dynamics of the wave-breaking process in the wave reflection area. Results also indicate that mesh density has a more significant influence than the time step. Overall, this paper showcases the entire process of establishing two-phase flow CFD (computational fluid dynamics) simulations in OpenFOAM® and provides a reference model for future research on studying the effectiveness of eco-retrofitting approaches on wave attenuation.
Goods and Services
Authors: Vale Gina 
Published: August 2024

Abstract
Investment in and management of public welfare were integral to Islamic State’s (IS) aspirations, branding, and pragmatic legitimacy as a governing actor. Yet, this chapter reveals that access and quality of these goods and services were neither universal nor guaranteed. In particular, civilian women’s differing eligibility for IS ‘citizenship’ and its associated benefits serve to shatter the veneer of the group’s ‘inclusive’ service provision and employment opportunities. Adding to studies of IS’s governance, the testimonies of local Iraqi, Syrian, and Kurdish women shed light on undocumented impacts and aspects of the group’s public institutions, including the strict policy of sex segregation. Complicating the public–private divide, the creation of semi-public women-only spaces was a double-edged sword. While the exclusion of men provided a layer of protection and freedom, it also brought previously private and feminine spaces under surveillance and control by pro-IS women, exposing the parameters of the group’s intra-female hierarchy.

Published: August 2024

Abstract
Insulinomas represent &lt;10% of pancreatic tumors. It is a functional neuroendocrine tumor that can cause recurrent and severe episodes of loss of consciousness due to hypoglycemia. Surgical removal is the only curative treatment. The selection of the optimal surgical technique must be individualized for each patient. Currently, there are emerging innovations in less invasive techniques that reduce morbidity. We present the case of a 23-year-old woman who underwent enucleation of an insulinoma localized at the tip of the pancreatic tail after laparoscopic surgery, with a focus on vascular and splenic preservation. The tumor was safely identified during surgery and enucleated without injury to the spleen and adjacent vascular structures or postoperative complications.

Published: August 2024

Background:
A total of 42 cases of moderate and severe breast ptosis were treated with sequential liposuction modified double ring areola incision surgery (experimental group), and 45 cases were treated with traditional double ring areola incision alone surgery (control group).

Methods:
They were followed up for 6 months after the operation. The scar formation and breast ptosis repair were observed, and postoperative complications and patient satisfaction were monitored.

Results:
Better results such as improved postoperative breast appearance were achieved in the sequential liposuction modified double ring areola incision group compared with the double ring areola incision alone group. After treatment, the distance between the midpoint of the inframammary fold and the nipple, the distance between the suprasternal fossa, and the nipple of the two groups were lower than those before treatment. The distance between the midpoint of the inframammary fold and the nipple showed no difference between the two experimental groups. The distance between the suprasternal fossa and the nipple of the experimental group were lower compared with the control group. Lower complication rates and higher satisfaction rates were observed in patients treated with sequential liposuction modified double ring areola incision. The patients in the experimental group were more satisfied with breast symmetry, breast shape, and breast size than those in the control group.

Conclusions:
The treatment with sequential liposuction modified double ring areola incision was effective and safe compared with double ring areola incision alone. It could improve the breast shape of patients, improve the satisfaction of patients, and reduce the occurrence of complications.
Efficacy and Safety of Standard Triple Therapy for Helicobacter pylori Eradication in Latin America
Authors: Díaz-Rodríguez Dahiana M. , Bustamante-Rengifo Javier A. , García-Perdomo Herney A. 
Published: August 2024

Goals:
To evaluate the efficacy and safety of standard triple therapy (STT) in Latin America.

Background:

Helicobacter pylori infection affects more than 50% of the Latin Americans and leads to gastric mucosa damage. Scarce data on effective therapeutic approaches in the region underscores the need for comprehensive information.

Study:
The analysis included Randomized Controlled Trials published up to the year 2020, comparing STT with other treatments. Cumulative relative risks (RR) were estimated, with 95% CI, according to intention-to-treat (ITT) and per protocol (PP) analysis.

Results:
Eleven studies (clinical trials conducted between 1995 and 2013), revealed cumulative eradication rates of 78.31–90.63% (ITT) and 76.71–93.55% (PP). The eradication with the STT was superior to sequential therapy (ITT—RR: 10.6, 95% CI: 1.01 to 1.12) (PP—RR: 10.6, 95% CI: 1.02-1.11) and dual therapy (ITT—RR: 1.61, 95% CI: 1.13-2.30) (PP—RR: 1.72, 95% CI: 1.25-2.37), but is less effective than other triple therapies (PP—RR: 0.85, 95% CI: 0.78-092). Regarding adverse effects, diarrhea, metallic taste, nausea, vomiting, and headache were the most common symptoms across treatments. Abdominal pain was associated with STT (ITT—RR: 1.75, 95% CI: 1.07-2.86).

Conclusion:
STT was a safe regimen but with acceptable efficacy (most eradication rates <90%). Due to rising clarithromycin resistance, the study suggests avoiding STT as a first-line treatment. These results must be considered with caution due to the low representativeness of several Latin American countries and the lack of recent high-quality randomized studies.
