Advanced Beam Estimation for Antennas Via Patterned Coupling-Line Detection Board in Ka-Band
Authors: Hong Seokyeon , Nam Seunggoo , Choi Sehwan , Joo Jihan , Han Jaesub
Published: September 2024

In this research, we present an innovative method for estimating the beams of array antennas. Traditional beam analysis methods rely on placing receiving antennas in the far-field region, which requires moving or rotating the Tx or Rx, and using radiation pattern measurements. However, such methods often demand vast spatial requirements and the use of high-cost network analyzers. In contrast, the technique proposed in this study utilizes a board patterned with coupling lines strategically placed in the antenna's near-field zone. Signals intercepted by these coupling lines undergo conversion into DC voltage via a power detector situated at the line terminus. Interestingly, this method enables beam estimation solely based on the DC voltage level output of the power detector, thus offering a cost-effective and space-efficient solution that represents a significant advancement from traditional beam estimation methods.

La intensificación con el sistema milpa intercalada con árboles frutales (MIAF) está logrando los objetivos planteados: la seguridad alimentaria, el incremento de la eficiencia relativa de la tierra (ERT), la protección del suelo contra la erosión y el incremento significativo del ingreso neto familiar. Sin embargo, también es evidente que existe la necesidad de seguir explorando nuevas alternativas para intensificar aún más el uso de la tierra de labor, de acuerdo a las condiciones climáticas y de suelo específicas de diferentes regiones del país. Por ello, el objetivo de la presente investigación fue estudiar la respuesta del rendimiento de maíz y frijol al método de labranza y al arreglo topológico en un Vertisol. Este estudio se realizó en el campo experimental centro de Chiapas (CECECH) del Instituto Nacional de investigaciones Forestales, Agrícolas y Pecuarias (INIFAP). Los factores estudiados fueron el arreglo topológico (AT) a tres niveles: 1 × 1, 2 × 2 y 2 × 2sa (surco angosto) y método de labranza (MDL) a dos niveles: labranza de conservación (LC) y labranza convencional (LCV), en combinación factorial, bajo un diseño experimental completamente al azar con dos repeticiones. En un año en el que se presentó sequía, se obtuvieron diferencias estadísticas (P ≤ 0.05) entre MDL para el rendimiento de maíz y el más alto se obtuvo en los tratamientos con LC. El rendimiento de frijol fue afectado por la interacción AT × MDL (P ≤ 0.05). La ERT máxima se obtuvo con el tratamiento 2 × 2 LCV. La reducción del ancho del surco aún con una mayor densidad de población y dosis de fertilización por m2 con el AT 2 × 2sa no aumentó significativamente el rendimiento en las condiciones que se llevó a cabo el trabajo.

Published: September 2024

The objectives of this work were to search for and evaluate arbuscular mycorrhizal fungi (AMF) in six crops of agricultural importance in the horticultural region of Tepeaca valley, Puebla, Mexico, where Cambisols type soil predominates since the communities and consortia of AMF and their functionality in various crops of economic importance in Mexico are still unknown. The search for and identification of AMF spores was carried out in dif ferent vegetable crops. Five subsamples were collected from 6 dif ferent crop fields with vegetables (cilantro, cabbage, spinach, parsley, lettuce, and pumpkin); each subsample consisted of soil and roots. Roots 5 mm long were selected and stained using the Phillips-Hayman technique. Spore extractions and physicochemical determinations (soil texture, pH, relative humidity (RH), and electrical conductivity (EC)) were performed from soil. The results obtained from staining showed vesicles and spores in roots except in the pumpkin subsamples; of spore extractions from the soil of the six crops, 9 genera and 14 morphotypes of mycorrhizae were found, highlighting Funneliformis mosseae, Claroideoglomus Claroideum, and Glomus sp. as dominant species. By soil physicochemical characterizations were found: sandy texture, pH between 5.8 to 6.8; RH of 9.4 to 13%, and EC of 0.10 to 0.93 mS cm-1. In conclusion, the analyses of similarity and main components suggested that species of vegetables and soil conditions do not af fect the spore abundance, but they do af fect the richness and composition of AMF species, observing particular mycorrhizal consortia for each crop; therefore, it is suggested to evaluate their ef fectiveness in each of the crops to promote them as biofertilizer in the agricultural region of Tepeaca valley, Puebla, Mexico.

La solución del suelo (SS) constituye el volumen de donde las raíces de las plantas extraen los nutrientes disueltos. A pesar de su importancia, el impacto de su composición por la aplicación de enmiendas orgánicas se encuentra relativamente poco estudiado. El objetivo de esta investigación fue estudiar el impacto de los ácidos húmicos (AH) y quitosán (Cs) sobre la concentración de los minerales en la SS, así como su efecto en el rendimiento del cultivo de col (Brassica oleracea L.). En condiciones de invernadero con suelo calcáreo se aplicaron dos dosis de AH (200 y 500 kg ha-1), así como 50 y 150 kg ha-1 de Cs de forma dirigida. De la SS se tomaron 22 muestras en forma no destructiva de la zona de la raíz una vez por semana. Los resultados del contenido mineral en la solución del suelo y del contenido mineral en la biomasa no presentaron diferencias significativas, no obstante, se apreció que el tratamiento Cs50 estimuló 41% la biomasa vegetal superior al testigo (P ≤ 0.5, Tukey). Se concluye que el Cs y AH no impactan significativamente el contenido iónico de la SS ni el contenido mineral de la biomasa, aunque si estimulan el rendimiento.

Los bioestimulantes como el quitosano en la agricultura tradicional han demostrado su eficacia para promover el crecimiento y desarrollo de las plantas, así como protegerlas de enfermedades, sin embargo, en sistemas de producción acuapónicos su efecto no está documentado, por ello el objetivo del presente trabajo fue determinar el efecto de la concentración de quitosano (0, 500 y 1000 mg.L) en tres variedades de lechuga (Grandes Lagos, Regina 500 y Red Rock), sobre los parámetros de producción de lechuga y la presencia de enfermedades en un sistema circular de acuaponia. Bajo un arreglo factorial de 3x3 el quitosano fue aplicado mediante aspersión a los 10 y 45 días después del trasplante. Se utilizó una análisis de varianza y comparación de medias con la prueba de Tukey para el efecto de la variedad, y polinomios ortogonales para el efecto de la concentración de quitosano, y un análisis de correlación y regresión para determinar la relación entre el rendimiento y la altura y el número y longitud de las hojas.  Los resultados demuestran que las variables número de hojas, longitud de la raíz, peso de la planta, longitud de la hoja, altura de la planta y rendimiento, se incrementan conforme se aumenta la dosis de quitosano. La variedad Red Rock superó a las variedades Regina 500 y Grandes Lagos. No se detectó la presencia de insectos ni enfermedades. Se concluye que el quitosano favorece el crecimiento, desarrollo y rendimiento de la planta de lechuga en un sistema circular de acuaponía, sobre todo con dosis de 1000 mg.L de quitosano, y que respecto a estas mismas variables, la variedad Red Rock supera a las variedades  Regina 500 y Grandes Lagos.

Published: September 2024

La higuerilla (Ricinus communis L.) es una planta que tiene diferentes beneficios, como la producción de biodiesel y la biorremediación de suelo. Debido a lo anterior, se evaluó la capacidad de la higuerilla para extraer arsénico (As). Para ello, se realizó un diseño experimental de bloques al azar con cuatro repeticiones. Los tratamientos evaluados consistieron en dos tipos de biosólidos (biosólidos de lagunas de oxidación (BLO) y biosólidos de lodos activados (BLA) y cuatro dosis de As (0, 25, 50, 100 mg kg-1), bajo condiciones de invernadero. La concentración de As se determinó por espectrometría de masas por plasma acoplado inductivamente (ICP-MS). A partir de la cuantificación de As se estimó el factor de translocación (FT) y el factor de bioacumulación (FB). El contenido de nitrógeno (N) total se cuantifico por el método de combustión. El fósforo (P) se analizó por colorimetría por el método de metavanadato, y el contenido de potasio (K), calcio (Ca), magnesio (Mg), cobre (Cu), manganeso (Mn), hierro (Fe) y zinc (Zn) que se cuantificaron por absorción atómica. Para porcentaje de aceite en la semilla se utilizó el método Soxhlet. La altura de planta y el peso seco de biomasa no variaron por efecto de tratamiento (P ≤ 0.05). El Factor de translocación (FT) y el Factor de bioconcentración (FBC) registraron rangos de 0.20 - 0.63 y 0.28 - 0.75, respectivamente. Las dosis aplicadas de As no afectaron la biomasa y absorción de nutrientes en la planta de higuerilla, lo cual indica que esta especie vegetal es tolerante a la toxicidad con potencial productivo en suelos contaminados con este elemento, en concentraciones hasta de 100 mg kg-1.

El tomate (Solanum lycopersicum L.) por su alta demanda y producción es la hortaliza más importante en el mundo aunado a esto es un alimento funcional por su contenido de antioxidantes. Este cultivo se produce bajo un sistema protegido con una fuente de fertilización inorgánica sintética, lo cual incrementa los costos de producción. Es importante encontrar una fuente alternativa de fertilización y un manejo agronómico que incremente los rendimientos, mejore la calidad comercial y nutraceútica de este cultivo. El objetivo del estudio fue comprobar el efecto sobre la calidad comercial y los compuestos bioactivos de tomate, con dosis de estiércol bovino solarizado y el número de tallos bajo un sistema protegido, así como evaluar el efecto de la fertilización orgánica en el suelo. La investigación se desarrolló durante el ciclo primavera-verano 2021. Se obtuvieron ocho tratamientos (factorial 4×2) originados de la combinación de cuatro dosis de fertilización (0, 40, 60 Mg ha-1 de estiércol solarizado y fertilizante químico [Urea (46-0-0) y MAP (11-52-0)] con dos números de tallos (uno y dos tallos) por planta. La calidad comercial fue superior organolépticamente con el tratamiento de 60 Mg ha-1 y con un solo tallo encontrándose superior a los 4.8 °Brix. El mayor rendimiento se obtuvo con la dosis de 60 Mg ha-1 de estiércol bovino siendo estadísticamente similar a la fertilización química. El contenido de compuestos bioactivos (licopeno y la capacidad antioxidante) se incrementó un 36% con el efecto de la interacción de 60 Mg ha-1 de estiércol y un tallo en comparación con el tratamiento químico. El contenido de MO, NO3-, NH4+y PO4-3 en el suelo se incrementó con las dosis de estiércol, por lo que se ve reflejado uno de los beneficios del uso de este abono orgánico.

In the Mexican southeast, hydrocarbon spills and their residues af fect various agricultural sites. A specific case is spills of oil production or congenital waters that cause soil salinization. When soil is contaminated, restorations are regularly carried out based on regulatory limits, but many regions still do not consider the pedological classification, so restorations are not entirely ef fective and, in the case of agricultural soils, reduce your productivity. For these reasons, this study evaluated the cation exchange with CaO applied to four soils contaminated with congenital waters and determined if there are dif ferences in the treatment behavior according to the properties of each soil. It will be found that sandy soils require less treatment time, but have greater ef fects on their properties compared to clay soils, mainly in field capacity, pH, and porosity. Furthermore, it was found that contaminant removal times vary with respect to the type of soil and that this could be related to the amount and type of clay. In the case of congenital water spills, clay soils show a greater increase in electrical conductivity (EC) compared to sandy soils. When remediated with CaO, clay soils needed longer treatment times to reduce EC, but presented fewer changes in their physical and chemical properties. In addition, it was found that, although washing with drinking water is carried out, the treatment with CaO adds alkalinity to the soils, so they must be managed according to the crop to be developed. It is concluded that soils have dif ferent physical and chemical properties, this influences the response they have to an external agent, both when contaminated and when remediated.

Authors: Elmas Özlem , Keser Şahin Havva Hande , Keskin Emrah , Apsar Başaran Özlem
Published: September 2024

Objective: The spinal cord is often involved in radiotherapy to treat malignancies and is considered as one of the most critical dose-limiting organs. Histopathological changes of radiation-induced spinal cord injury include gliosis, demyelination, and necrosis in the white matter, as well as vascular changes in both white and gray matter. All aerial parts of Annona muricata (AM) are used in traditional medicine practices, and previous studies revealed that AM leaf extract has radioprotective effect against gamma- irradiation. This study aimed to evaluate the possible protective effect of AM leaf extract against ionizing radiation spinal cord injury.
Methods: A total of 37 adult female Wistar Albino rats were divided into 4 groups (1 control and 3 intervention groups): Group 1 (control) received 0.01 mL/kg of distilled water by oral gavage once a day for 7 days, group 2 (AM group) received 300 mg/kg of AM leaf extract by oral gavage once a day for 7 days, group 3 (IR group) received a single dose of spinal cord radiation (20 Gy) after a 7-day treatment with 0.01 mL/kg of physiologic serum (saline), and group 4 (AM + IR group) received 300 mg/kg of AM leaf extract by oral gavage once a day for 7 days, with spinal cord radiation (20 Gy) applied 1 hour after the last gavage. After the sacrificing, spinal cords were dissected out, embedded in paraffin, and stained with Hematoxylin-Eosin, and 11 parameters were microscopically examined and scored.
Results: AM administration prior to irradiation (IR) lowered the histopathological scores for all parameters that were verified in the IR group at most severe levels: inflammatory cells infiltration, edema, neuron swelling, gliocytes hyperplasia, spinal cord cavitation (loosened tissue structure), pyknotic nuclei, vacuolar denaturation, and loss of Nissls substance. Necrosis was present in IR group and was higher compared to Control and AM treated groups. We noticed that necrosis was present in the AM group too and was higher compared to the control.
Conclusion: The data of our study suggest that pretreatment with 300 mg/kg of AM leaf extract prior to IR reduce inflammatory cells infiltration, edema, and neuron swelling. This supports the fact that AM-proposed anti-inflammatory property may contribute to neuroprotection. Similarly, AM was documented to have efficient protection on neural cells from apoptosis or necrosis.
Amyand’s Hernia: A Case Report
Authors: Köroğlu Ahmet Orçun , Taflan Sıtkı Safa
Published: September 2024

Amyand's hernia is defined as the presence of the appendix vermiformis (inflamed or non-inflamed) within the inguinal hernia sac. It is seen in approximately 1% of inguinal hernia cases. This extremely rare condition is often diagnosed conventionally, at surgery. However, with the increasing use of computed tomography (CT) and ultrasonography (US) examinations, preoperative diagnosis is also possible. The treatment approach varies depending on whether the appendix inside the hernia sac is inflamed or not. For this reason, imaging examinations are of great importance in making a diagnosis and directing treatment. As a result of imaging examinations in an elderly patient in our clinic, colon, small intestine segments, omentum and appendix were detected in the right inguinal canal. Since the appendix was also located within the hernia sac, the case was called Amyand's hernia. In this article, we wanted to draw attention to Amyand's hernia in general and the place of radiological examination in diagnosis and treatment of this disease.

Authors: Cengil Osman , Keçeci Mete
Published: September 2024

Acute respiratory distress syndrome (ARDS) is a serious pulmonary reaction with well-defined clinical parameters in humans triggered by many causes besides bacterial and viral pneumonia. However, there is no definitive definition of ARDS parameters in the experimental animal model. With its 2010 workshop report, the American Thoracic Society defined the main histopathological features that determine the presence of ARDS in laboratory animals, such as changes in parenchymal tissue, altered integrity of the alveolar capillary barrier, inflammation, and abnormal lung function. Understanding these parameters, scoring tissue lesions is used to convert observational pathological data into semi-quantitative or quantitative data for statistical analysis and improved precision.

Impact of Crude Oil Pollution on some Geotechnical Characteristics of North Rumaila Soils in the Southern Iraqi Province of Basrah Governorate
Authors: Al-Nimah Ahmed K. , Mahmood Raid A.
Published: September 2024

Background:
Pollution affects the soil and results in a change in its natural, chemical, or organic characteristics and properties, which directly or indirectly affect the geotechnical properties of the soil and make it unsuitable for engineering use. The aim of the study is to determine how adding various amounts of crude oil to the study area's soil affects the soil's geotechnical characteristics, including soil shear resistance, compaction coefficients, and California bearing capacity.
Materials and Methods:
The North Rumaila site was chosen for the study. At a depth of one meter, natural, pollution-free soil was extracted, and weight percentages of 2%, 4%, 6%, 8%, and 10% of crude oil were added. Grain size analysis, moisture content, direct shear, compaction, and Californian bearing tests were conducted.
Results:
The findings indicate that the soil at the North Rumaila site has a moisture content of 6.45% and is mostly silty sand with small amounts of clay and gravel. Crude oil was added to the soil, which caused the Californian to lose some of its bearing capacity, the optimal moisture content to raise, the angle of internal friction to decrease, and the bearing capacity of the soil to decrease.
Conclusion:
Pollution by crude oil effects negatively impacted the soil's geotechnical qualities.
Improving The Geotechnical Properties of Cohesive Soils Using Portland Cement and Some Composite Polymers in A Selected Location in The City of Tanumah / Basrah Governorate – Southern Iraq
Authors: Al-Subaie Tuqa Amer , Mahmood Raid Aziz , Jaber Muhammad Ali
Published: September 2024

Background:
The purpose of this research is to ascertain how adding Portland cement and composite polymers, as well as the ideal ratios between them, will affect cohesive soils' geotechnical characteristics.
 Materials and Methods:
A composite polymer was created by combining three polymers—isocyanide, unsaturated polyester, polyvinyl acetate, and thinner—as well as a solvent. Portland cement was added to the soil at a rate of 5% of the sample weight. Different percentages of the weight of the cement supplied to the sample—5, 10, 15, 20, and 25%—were utilized as the composite polymer. Several geotechnical tests were carried out, including compaction, unconfined compressive strength, California bearing ratio, absorption, and Atterberg's limits, to ascertain the ideal amount of polymer for the aim of improvement.
Results:
The findings show that adding cement at a rate of 5% by weight of the sample and a polymeric mixture at a rate of 15% by weight of cement can improve the cohesive soil's engineering properties. It was found that the maximum dry density, unconfined compressive strength, and California bearing ratio had increased while the values of the optimal moisture content, absorption rate, liquid limit values, and plasticity index had decreased.
Conclusion:
The composite polymer used in soil improvement not only improves the geotechnical properties and resistance of the soil, but it also efficiently enhances and activates the effectiveness of cement. When 15% of the sample's weight of cement was composed of composite polymers, the soil's engineering attributes increased the most.
How Do Grice and Strawson End Up in a Rabbit Hole?
Authors: Aydemir Yunus
Published: September 2024

Since Kant’s usage of analytic and synthetic to divide propositions into two categories, there have been many different philosophers who have used the same distinction over time. However, this does not necessarily mean that every philosopher
who uses this distinction for their philosophical purposes actually favors it. The most important of all is unquestionably Willard Van Orman Quine. He defines the existence of the distinction as an unempirical dogma of empiricists
or a metaphysical article of faith. To him such a distinction does not exist. He believes he offers enough proofs for this claim in his Two Dogmas of Empiricism. Alternatively, Grice and Strawson strongly believe in the distinction.
Therefore, they write an article, namely In Defense of a Dogma, to refute Quine’s claims. The main objective in this study is to demonstrate that the response by Grice and Strawson does not work at all.

The problem of diagnosing primary hyperaldosteronism remains relevant. A rare manifestation of primary hyperaldosteronism is secondary hypokalemic myoplegia, which may be the initial manifestation and cause difficulties in diagnosing primary hyperaldosteronism. It is expedient to describe new cases of primary hyperaldosteronism with an analysis of clinical features, possible diagnostic errors and difficulties. A clinical case of a patient with hypokalemic myopathic syndrome is presented. The level of potassium, aldosterone, renin in blood plasma was studied, and the aldosterone-renin ratio was determined. Adrenal adenoma was con-firmed by multispiral computed tomography and histology. Clinical observation demonstrates differential diagnostic difficulties of primary hyperaldosteronism, which were associated with a variety of clinical manifestations, nonspecificity of symptoms, dependence on the presence of hypokalemia, and erroneous diagnoses in anamnesis. Attention is drawn to the longterm normocaliemic course of primary hyperaldosteronism with arterial hypertension, which was regarded as a hypertensive disease. Primary hyperaldosteronism was suspected when myopathic syndrome appeared and dominated the clinical picture of the disease. Primary hyperaldosteronism, determining the occurrence of secondary hypokalemic myoplegia, presents significant differential diagnostic difficulties and requires physicians to be aware of the features of the clinical manifestations of primary hyperaldosteronism, alertness to the adrenal tumor, adequate assessment of the clinical picture, the use of a modern complex of diagnostic tools, internosological diagnostics and a multidisciplinary approach to therapy.

Pembakaran adalah metode konversi energi dengan mereaksikan bahan bakar dan oksigen untuk menghasilkan panas. Saat ini batubara masih mendominasi sumber energi di Indonesia yang menyumbang lebih dari 50% emisi CO2 global. Upaya mengurangi emisi ini salah satunya dengan penggunaan energi terbarukan seperti biomassa, dimana energi biomassa yang sedang berpotensi saat ini adalah produk biomassa tanaman energi seperti kayu gamal dan sengon. Penggunaan tanaman energi tersebut sebagai penyedia termal melalui proses pembakaran masih belum pernah dikaji, sehingga paper ini akan membahas karakteristik termal pembakaran kayu gamal dan sengon secara teoritis melalui simulasi numerik pembakaran. Simulasi menggunakan model kesetimbangan pembakaran pada tungku adiabatik dengan kondisi stoikiometri, kelebihan udara (excess air), dan kelebihan bahan bakar (excess fuel) dengan perhitungan – perhitungan termodinamika yang nantinya akan divalidasi dengan data eksperimental. Hasil simulasi menunjukkan karakteristik termal pembakaran gamal lebih unggul dibandingkan sengon. Penambahan dan pengurangan udara dari kondisi optimum dapat mengurangi kualitas pembakaran, namun secara aktual penggunaan udara berlebih diperlukan untuk mengantisipasi faktor lingkungan yang mengganggu pembakaran stoikiometri teoritis.  Kondisi optimum pembakaran dicapai pada saat rasio ekuivalen gamal dan sengon masing-masing 1,3. Hasil validasi menggunakan MAPE menunjukkan nilai error yang rendah (8,55%) sehingga model pembakaran yang digunakan mampu memprediksi karakteristik termal dengan sangat baik.

Minyak goreng umumnya digunakan untuk menggoreng bahan pangan terutama dalam metode deep-fat frying pada tekanan atmosfer. Variasi pada hasil gorengan disebabkan oleh berbagai faktor, di antaranya jenis bahan makanan, jenis minyak goreng, durasi penggorengan, temperatur minyak goreng, dan frekuensi penggorengan. Penelitian ini bertujuan untuk mengkaji pengaruh variasi suhu dan frekuensi penggorengan terhadap kualitas kentang goreng yang digoreng menggunakan minyak kelapa hasil produksi sendiri.  Minyak kelapa dibuat dari santan yang dipretreatment dimana santan sebelum diolah disimpan pada suhu dingin. Kentang digoreng dengan perlakuan suhu 140 °C, 160 °C, 180 °C, dan 200 °C, proses frekuensi dilakukan berulang sebanyak 9 kali dengan penggorengan berturut-turut. Pengamatan kandungan air, tekstur, dan warna kentang goreng dievaluasi pada akhir penggorengan ke-3, ke-5, ke-7, dan ke-9 pada masing – masing suhu penggorengan. Hasil penelitian menunjukkan bahwa perlakuan suhu pada setiap frekuensi penggorengan tidak berpengaruh nyata dan semakin tinggi suhu kadar air semakin rendah, tekstur semakin tinggi suhu nilai tekstur semakin tinggi (0,3467 kgf - 0,8067 kgf), dan perubahan warna terbesar pada perlakuan suhu 200°C, Berdasarkan hasil penelitian, disarankan untuk menggoreng kentang pada suhu maksimal 180 °C dan dengan frekuensi penggorengan tidak lebih dari 9 kali untuk mendapatkan produk kentang goreng dengan kualitas yang baik, renyah, dan aman dikonsumsi.

Phyllanthus niruri is traditionally used to treat intestinal worms. The content of flavonoids in Phyllanthus niruri has the potential as an anthelmintic. The aims of study are to identify flavonoid compounds of the ethanolic extract of Phyllanthus niruri and determine the anthelmintic activity against Paramphistomum spp. Paramphistomum spp. grouped into positive control (Albendazole 10% w/v), negative control (CMC-Na 0.5% w/v), ethanolic extract of Phyllanthus niruri 1.25%, 2.5%, and 5% w/v. For 5 hours, the time and quantity of dead worms were counted every 15 minutes. The average time of death and percentage of worm mortality were then calculate. Differences in average time of death were analyzed with Kruskal-Wallis and Mann Whitney. The results of the test tube and TLC showed the content of flavonoid compounds. Percentage of mortality of Paramphistomum spp. obtained by 100%. Average death time of Paramphistomum spp. at 50, 275, 155, 140, and 115 minutes respectively. Ethanolic extract of Phyllanthus niruri contained flavonoid compounds and has anthelmintic activity with an optimum concentration of 5% w/v although lower than Albendazole 10% w/v (p<0.05).

Anti-dandruff shampoo on the market still uses zinc pyriton which has the side effect of causing hair loss. Pomegranate leaves have strong antifungal activity against dandruff-causing fungi. This research aims to determine the optimum formula and physical properties of pomegranate leaf shampoo preparations with variations of SLS and cocamide DEA. The ethanol extract of pomegranate leaves was extracted by soxhletation and carried out in a tube test. Eight shampoo formula designs were determined using the SLD method. The shampoo was tested for foam height, pH, and viscosity to obtain the optimum formula. The optimum shampoo preparation was tested for physical properties, including organoleptic tests, homogeneity, foam stability, foam height, pH, and viscosity. The results of the test for the physical properties of the optimum shampoo preparation were verified using the SPSS application with the one-sample t-test method. Pomegranate leaf ethanol extract positively contains alkaloids, flavonoids, tannins, and saponins. The optimization results obtained the optimum shampoo formula, namely a combination of SLS 5.5% and cocamide DEA 15.5%. Optimum formula shampoo has a black color, menthol odor, gel form, ingredients mixed homogeneously, foam stability 81.83%, foam height 9.30 ± 0.26 cm, pH 5.91 ± 0.45, and viscosity 1646.66 ± 220.23 cP.
