COMPOSTAGEM DE RESÍDUOS DE PODA EM UM CONDOMÍNIO HORIZONTAL
Authors: De Faria Henrique Rodrigues Americano , Pfeiffer Simone Costa
Published: February 2024

Objetivo: Avaliar a compostagem de resíduos de poda realizada em um condomínio horizontal do município de Goiânia, Goiás.
Referencial teórico: Em Goiânia, os condomínios horizontais são considerados grandes geradores e devem assumir o gerenciamento de seus resíduos. Embora a compostagem seja uma forma de aproveitamento dos resíduos orgânicos, diferentes fatores, tais como temperatura, aeração, umidade e pH, interferem no processo e precisam ser acompanhados.
Método: Cinco leiras já formadas foram acompanhadas durante três meses. A temperatura, o pH e a umidade foram medidos em três pontos distintos de cada leira duas vezes por semana. Foi realizada, também, a análise nutricional da leira mais antiga.
Resultados e conclusão: O uso exclusivo de resíduos de poda resultou em um processo demorado e prejudicou a qualidade nutricional do composto. No entanto, a compostagem teve um papel importante na gestão dos resíduos sólidos gerados no condomínio estudado, uma vez que, com a implementação do processo, 1.836 t/ano de massa verde deixaram de ser dispostas no aterro sanitário.
Implicações da pesquisa: Este estudo contribui para a promoção de padrões ambientalmente mais sustentáveis e para o atendimento da legislação pertinente.
Originalidade/valor: Considerando que, em Goiânia, o gerenciamento dos resíduos é de competência dos condomínios horizontais, este estudo apresenta uma alternativa de destinação viável para esses geradores.

Published: February 2024

Purpose: Analyze sustainability in the socio-environmental management of the judiciary, from the perspective of indicators defined by the National Council of Justice (CNJ) and propose a sustainability index for the socio-environmental management of the PJ.
 
Theoretical framework: Indicators are present in everyone's lives, they are everywhere. They are considered a management tool. Models for assessing sustainability through specific indicators and indices have been the subject of study in several studies, from the perspective of different dimensions.
 
Method: Application of the methodology proposed by Calório (1997), combined with Daniel et al (2001), Sobral, Almeida and Gomes (2012), Faccioli and Gomes (2021) and adaptations, with 21 indicators in the environmental, economic and social dimensions in 9 categories defined by the CNJ aligned with the Sustainable Development Goals (SDG). The Sustainability Index, its classification and scenario analysis are obtained.
 
Results and discussion: An index and model aimed at evaluating the socio-environmental sustainability of the judiciary is presented, in which the general sustainability index - IS0-100 was 20.24%, a level considered bad and classified as a pessimistic scenario, pointing out a warning for the economic and environmental dimensions, in the categories: paper, disposable cups, electricity and mineral water, due to expenses/consumption. The indicators consumption of returnable packaging for mineral water (IA9) and expenditure on mineral water in returnable packaging (IE8) presented the highest level of unsustainability (0.0%).
 
Implications of the research: This research demonstrated that the methodology can be applied to the Judiciary sphere, in the Courts of Justice, and that it has implications in the form of monitoring, and can be used as a parameter for evaluating sustainability in socio-environmental management and contribute to decision-making.
 
Originality/value: The literature is silent in relation to socio-environmental management in the judiciary with the SDGs, there is a lack of studies to assess sustainability. Thus, the knowledge developed in this research fills a gap by proposing a Sustainability Index for this sphere of power.

Published: February 2024

Aim. To study the possibilities of participation of a clinical pharmacist in complying with modern guidelines for antihypertensive pharmacotherapy using fixed combinations of drugs in the conditions of a pharmacy and determine the directions for improving the work of a clinical pharmacist to improve the quality of hypertension control.
Materials and methods. The analysis of reports on the sale of antihypertensive drugs containing one active substance and fixed combinations of two or three active substances was carried out in a pharmacy at a healthcare institution.
Results. Sales volumes of combined drugs prevailed over sales volumes of drugs that contained one active substance, and fixed combinations of two active substances prevailed over triple combinations. However, the frequency of selling two drugs of different groups as separate drugs was higher than the sale of drugs of two or three pharmacological groups as fixed combinations. At the same time, sales of fixed combinations prevailed for individual active substances among the angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers.
Conclusions. Data on the sale of fixed combinations of two or three active substances in the pharmacy have demonstrated insufficient compliance with current guidelines for antihypertensive pharmacotherapy. One of the ways to improve compliance with modern guidelines for the use of fixed combinations is the active participation of the clinical pharmacist in the selection of drugs for a particular patient, actively interacting with the doctor. Thus, a clinical pharmacist can be an important link in the control of arterial hypertension and the implementation of modern guidelines for the pharmacotherapy of arterial hypertension.

Published: February 2024

The influence of thermal/chemical nonequilibrium on a hydrogen-fueled [Formula: see text] 10 scramjet was analyzed by combining the JF-2 4 s hock tunnel test and improved delayed detached eddy simulation modeling. A remarkable change in flame stabilization mode when incorporating the two-temperature nonequilibrium model was observed. The nonequilibrium heating and cooling effects were analyzed for different sections of the scramjet. The nonequilibrium heating effect facilitates the upstream flame propagation by inducing an early ignition and thickening the inlet boundary layer. The nonequilibrium heating or cooling effect is generally weak in the nearly constant-area isolator and combustor, where the flow is mainly influenced by the chemical nonequilibrium with a variation of 10% in reaction rate. The nonequilibrium cooling effect mainly exists in the expanding nozzle, where [Formula: see text], but the energy replenishment from vibrational mode to trans-rotational mode is nearly frozen when [Formula: see text]. Under both conditions, the final mixing is nearly complete, and net thrust has been achieved. When considering the nonequilibrium effects, the final combustion efficiency increases from 87.68 to 99%, together with a 53.94% rise in peak pressure ratio and a 137.04% rise in specific impulse.
Research and Analysis of Coulomb Friction in Landing Gear Shimmy
Authors: Ruan Shuang , Zhang Ming , Nie Hong
Published: February 2024

Aircraft are subject to small disturbances during taxiing, many of which are accidental and difficult to explain. Although nonlinear factors are considered in traditional analysis, Coulomb friction is generally ignored, and the interaction and common effects of nonlinear factors are mostly not discussed. In this paper, the dynamic model of shimmy is established, and the influence of Coulomb friction on shimmy is studied by using bifurcation theory and the structural mechanics analysis method. The results show that the system with Coulomb friction has subcritical Hopf bifurcation and that the system with square damping has supercritical Hopf bifurcation. Although the two do not change the stability of the system, their cooperation can improve the stability of the system. The Coulomb friction torque of the system has a complex piecewise functional relationship with the stability distance, rake angle, and acceleration. Some combinations will lead to very low Coulomb friction and deteriorate the anti-interference ability of the landing gear. This paper provides theoretical basis and support for the rational design of structural parameter collocation, enhancing the antidisturbance ability of the system during constant-speed or variable-speed taxis and explaining the shimmy phenomenon in the process of variable-speed taxis of some aircraft.
Stream-Surface Iteration-Based Flowfield Calculation Method for Pressure-Controllable Waverider Design
Authors: Sun Weiqiang , Zheng Xiaogang , You Yancheng
Published: February 2024

The performance of waveriders is greatly influenced by the wall pressure distribution. To achieve the goal of designing a waverider based on the complex two-dimensional pressure distribution, this study proposes a methodology called the stream-surface iteration-based flowfield calculation (SIFC) method. This method discretizes the three-dimensional flowfield with curved stream surfaces and approximates the flow around each point with a unique axisymmetric flow. Moreover, this method iteratively solves the shape of each stream surface and the corresponding flowfield to deal with ill-posed problems. To verify its effectiveness, the SIFC method was first applied to inversely solve the two external annular supersonic flowfields. Then, it was used for the waverider design. The computational fluid dynamics results showed that the relative error of the wall pressure was less than 2.6% for the annular supersonic flowfields. The wall pressure determines the geometric shapes and mechanical properties of waveriders. The pressure center of a waverider can be shifted by 12% of the length in the flow direction and 7.4% of the width in the crossflow direction by altering the input wall pressure. This shift will cause the waverider to produce more than 30% extra trim drag when cruising at the design Mach number.

Analysis of the epidemiological situation and dynamics of the incidence of sexually transmitted infections in the Russian Federation over a ten-year period (2012–2022)
Authors: Rakhmatulina Margarita R. , Novoselova Elena Yu. , Melekhina Lidia E.
Published: February 2024

Sexually transmitted infections (STIs) are socially significant diseases and require close attention due to the multifactorial causes that influence their spread. In 2012–2022, the Russian Federation maintained a downward trend in the incidence of STIs (from 267.6 to 91.3 cases per 100 thousand population), established since 1998 in all age groups. In 2022, compared to 2012, the incidence rates decreased: syphilis — by 42.7%; gonococcal infection — by 77.7%; trichomoniasis — by 75.8%; chlamydial infections — by 72.1%; anogenital herpetic infection — by 51.2%; anogenital (venereal) warts — by 36.5%. But at the same time, in 2021 and 2022, there was an increase in the incidence of syphilis and gonococcal infection: compared to 2019, the increase in the incidence of syphilis was 25.9%, and that of gonococcal infection — 5.2%. The increase in the incidence of syphilis was largely due to an increase in this indicator in the Central (from 18.1 to 37.3 cases per 100 thousand population) and Northwestern (from 14.5 to 16.2 cases per 100 thousand population) federal districts ( FO). An increase in the incidence of gonococcal infection in 2022 compared to 2019 was observed in the Central (+26.3%), Northwestern (+31.2%) and Ural (+27.6%) Federal Districts.

Objetivo: Relatar um estudo de caso sobre hiperglicinemia não cetótica e o tratamento nutricional prescrito com dieta cetogênica. Detalhamento do caso: Paciente do sexo feminino, com 3 anos de idade, natural de Cajazeiras-PB. Foi admitida num Hospital Universitário (EBSERH) da cidade com quadro de sonolência excessiva, associado a piora do quadro de crises convulsivas. Nos primeiros dias de internamento, a paciente utilizou uma dieta 4:1 semelhante a que estava ingerindo em casa. No quarto dia de reposição de potássio os níveis sanguíneos desse mineral reduziram significativamente mesmo a terapia de reposição não ter sido cessada o que gerou a suspeita de que a dieta cetogênica em 4:1 pudesse estar influenciando o quadro. Assim foi realizada involução da dieta passando para 3:1 e logo em seguida 2:1 e nessa concentração a paciente conseguiu manter os níveis de potássio normais e recebeu alta. Considerações finais: Considera-se que a dieta cetogênica apresentou-se como importante estratégia nutricional no controle das convulsões na hiperglicinemia não cetótica, porém a utilização dessa dieta de modo prolongado, sobretudo nas concentrações de 4g de gordura para 1 g de carboidrato foi relacionada ao desenvolvimento de hipocalemia.

Authors: Jamal Iffat , Jeelani Ahmed Kamran
Published: February 2024

Familial multiple coagulation factor deficiencies are a group of rare inherited disorders that are characterized by the simultaneous decrease in the levels of two or more coagulation factors. Common synchronous deficiencies are factors VIII and IX and combined deficiency of Vitamin K-dependent coagulation factors (factors II, VII, IX, and X). Here, we report a case of synchronous dual deficiency of factor VIII and IX, which is an extremely rare occurrence and no case report has been mentioned so far to the best of our knowledge. Recognizing such a dual deficiency is very important for proper management of patients.
Nobel Prize in physiology or medicine 2023: Development of mRNA therapeutics that paved the path of formulation of COVID-19 vaccine
Authors: Mandal N. C.
Published: February 2024

Since the concept of the vaccine was developed by Edward Jenner in 1796, vaccinology has traveled a long way with gradual improvement toward developing better methods of formulation of vaccines. In this premises in the 1990s, Karikó and Weissman joined their hands and minds aiming at understanding how different RNA species interact with the immune system. During their long journey in this direction, they performed extensive studies involving well-conceived molecular biology-based experiments that resulted in a breakthrough discovery relating to RNA therapeutics in general and messenger RNA (mRNA) therapeutics in particular. In this endeavor, they developed mRNA technology that actually paved the path leading to the development of mRNA vaccine that has many advantages. In December 2019, when the deadly virus SARS-CoV-2 emerged, which, in no time, caused a pandemic as well as an epidemic, thereby throwing a fierce challenge to the total healthcare systems worldwide, it was possible to take care of that challenge through the formulation and manufacturing on a large scale the mRNA vaccine against SARS-CoV-2 using the above technology. Thus, mRNA technology has created a strong platform that has spelled out a great promise toward controlling any pathogen infection and saving human life through the development of mRNA vaccine at a quick pace. In this short review, an attempt will be made to highlight the contributions of Karikó and Weissman and how they led the formulation of a vaccine against COVID-19, which fetched them the Nobel Prize in Medicine or Physiology, 2023.

Published: February 2024

Dynamika oraz złożoność współczesnego świata to ważne wyzwania dla systemów edukacyjnych przygotowujących młodych ludzi do uczestniczenia w otaczającej rzeczywistości i radzenia sobie w niej oraz do aktywnego współtworzenia przyszłości. Przyspieszony postęp technologiczny i globalna konkurencja to czynniki towarzyszące egzystencji współczesnego człowieka i jednocześnie istotne determinanty ścieżki życiowej zmierzającej do uzyskania odpowiedniego statusu społecznego. Priorytetem staje się więc antycypacja przyszłości oraz kształcenie do zmian zachodzących w każdej dziedzinie społecznego funkcjonowania.
Potrzeby te dezaktualizują tradycyjne formy przekazu edukacyjnego i jednocześnie generują konieczność zastąpienia procesu wychowania adaptacyjnego wychowaniem innowacyjnym oraz antycypacyjnym, nastawionym na proces budowy i rozwijania nowych kompetencji. Ważnym zadaniem współczesnej szkoły jest więc otwarcie się na zmiany oraz poszukiwanie adekwatnych, dostosowanych do nowych potrzeb, wzorców pedagogicznego działania. Formułą nowej koncepcji kształcenia staje się preferowanie procesu uczenia się realizowanego w szkole jako organizacji uczącej się – w oparciu o założenia konstruktywistycznego modelu edukacji, zakładającego uznanie aktywności własnej dziecka za główny mechanizm jego zmian rozwojowych.

Trichinellosis is one of the most dangerous zoonosis. The analysis of different methods of prevention in helminthology indicates an increasing attention to such zoonotic diseases as trichinellosis in the World and Russia. Wild animals as a source of infection play the leading role in human infection. The task of present work is diagnostics, prevention of helminthozoonosis and improved monitoring and surveillance of the dissemination of trichinellosis. Practical application of expertise of meat and meat products from hunter’s trophies allows preventing infection of human and domestic animals with dangerous zoonosis. The article considers the influence of low temperatures, and the improvement of the fight against trichinosis in the northern territories. The index and shape of the capsule of trichinella in carnivores have differences. Apparently, these features are due to the peculiarities of parasite-host relationships and differences in the morphology of muscle tissue myosymplasts in various animals, and are species-specific for the host animals of trichinella. The conducted studies confirm the effectiveness of the combination of methods of compressor trichinoscopy and digestion in the artificial gastric juice for postmortem diagnosis of trichinosis of wild animals. When comparing these methods, it was found that the method of digestion in artificial gastric juice is more sensitive compared to compressor trichinoscopy, but it is less effective in detecting dead trichinella. New technologies for disinfection of carcasses and residual muscle mass after hides have been milled have also been developed for mechanical harvesting stations; for this, special refrigerating chambers and solutions of disinfectants have been proposed. Trichinella of the northern territories are more resistant to low temperatures, therefore, disinfection modes should be increased (both temperature and exposure time). So, for example, if pork is frozen at a temperature of -15 oC, and according to the recommendation of the International Commission on Trichinosis, it is necessary to keep the meat for at least 3–4 weeks, and carcasses of wild animals should be frozen for at least 3 weeks at a temperature of less than -20 oC.
Status of coenopopulations of legumes (Fabaceae) on steppe pastures of the Altai Republic

The influence of grazing on the species of the Fabaceae family in the steppe communities of the Altai Republic was studied. It was found that on the steppe pastures of the middle mountains, there is a wide manifestation of signs of pasture digression, which mainly indicate the presence of intensive grazing of farm animals. The participation of leguminous plants in living aboveground phytomass in emerging transitional communities ranges from 25–50% in meadow steppes to 5–28% in real ones and up to 11–17% in desertified cenoses, which is largely determined by the peculiarities of their adaptation to pasture load and to natural and climatic factors. Under the influence of intensive grazing on the steppe pastures of the Altai Republic, accelerated aging and a decrease in the productivity of the aboveground mass are observed in most legume species. Enhanced grazing negatively affects both the morphometric parameters of all studied species and the ontogenetic structure of their coenopopulations. The degree of resistance to anthropogenic impact of each species is largely determined by its belonging to a particular life form and its lability. The least resistant to grazing and mowing were long-shoot caudex perennials, which are found only in the initial stages of herbage suppression, since with regular alienation of shoots they do not form seeds and quickly fall out of the herbage. Rhizomatous (Medicago falcata, Astragalus tibetanus) species can be kept in communities in the absence of seed renewal. Semi-rosette (Astragalus austrosibiricus, Hedysarum gmelinii) and rosette (Astragalus laguroides, A. testiculatus, A. dilutus, Gueldenstaedtia monophylla, Oxytropis pumila) tap-rooted perennials are capable of restoring cenopopulations after cessation of pasture load due to renewal buds remaining on perennial parts of the caudex. When growing conditions change (temporary cessation or reduction of pasture load, good moisture), adaptive reactions are activated aimed at the rapid growth of shoots after the removal of the negative factor.

One of the consequences of a special military operation to demilitarize and denazify the territories of Ukraine adjacent to the borders of the Russian Federation is the severe environmental consequences associated with the destruction of the natural landscape, close to the state of collapse – the irreversible loss of its biological productivity. It is necessary to develop and approve a federal target program to bring the territories where a special military operation was carried out into an ecologically safe state suitable for human life, as well as for representatives of the flora and fauna. The implementation of this federal target program will require an integrated approach to ensure the restoration of disturbed lands and their return to use for their intended purpose. It is quite natural that the restoration of degraded lands will have to be carried out with the obligatory consideration of the potential of plant-microbial complexes (natural or artificially created) in the course of soil bioremediation. The totality of theoretical and experimental data gives grounds to believe that the relevant designs are ready and possible to be introduced into the practice of bioremediation of degraded lands.

Comment on room temperature colossal superparamagnetic order in aminoferrocene–graphene molecular magnets
Authors: Athavan Gayathri , Coudert François-Xavier , Bedford Robin
Published: February 2024

A re-examination of recent claims of room temperature colossal superparamagnetic behaviour of a material based on graphene oxide (GO) modified by well-known aminoferrocene has been undertaken. The synthetic claims of the well-known and commercially available aminoferrocene do not bear scrutiny, neither from new data obtained nor from the data presented in the original paper. The density functional theory-derived model developed to describe the apparent magnetic properties of the material is based on an artefact that occurs through poor choice of the starting model for the GO.
How much sun is too much for surface oxygen vacancy rich-CeO2(0.3)/ZnO(0.7)@β-cyclodextrin quantum dots composites as smart sunscreen active ingredients: broadband UV shielding, cascade antioxidant, and biosafe

Published: February 2024

Ozone depletion has augmented photo-aging and sunburn caused by over-exposure to ultraviolet radiation (UVR). Widely used conventional sunscreens consisting of nanostructured inorganic UV filters – ZnO and TiO2, are potentially phototoxic and cause UV-induced DNA damage. This has led to new design considerations for active ingredients, emphasizing low cost, safety, and multi-functionality. In this study, broad-spectrum UV attenuation (250 nm-400 nm) and long-lasting photostability (> 5 h) are achieved in β-cyclodextrin functionalized, oxygen vacancy rich-ZnO/CeO2 quantum dots composites (VO●-CeO2(x)/ZnO(1-x)@β-CD QDs composite). The kinetically-driven synthesis exacerbates surface VO● concentration, modulating the band gap and facilitating enhanced molar absorptivity through photogenerated electron-hole separation. Additionally, surface VO● confers the nanocomposites with a self-cascading antioxidant effect, notably scavenging 62.8% of ●OH radicals. Endogenous O2 generation from H2O2 scavenging accelerated by Ce3+/Ce4+ couple benefits skin revitalization. The nanocomposites demonstrate remarkable cell viability (≥90%) and efficacy in alleviating sunburn, ageing, and ROS-induced skin ailments. Incorporating VO●-CeO2(0.3)/ZnO(0.7)@β-CD QDs composites as active ingredients in commercial sunscreens unveiled a substantial enhancement in the overall efficacy of sun protection. Thus, it is envisioned that VO●-CeO2(x)/ZnO(1-x)@β-CD QDs composites hold promise for developing newer, safe, efficacious, and economical sunscreen formulations, contributing to sustainable development goals.

Published: February 2024

We present four open-source datasets that provide results of density functional theory (DFT) calculations of ground-state properties of refractory solid solution binary alloys niobium-tantalum (NbTa), niobium-vanadium (NbV), tantalum-vanadium (TaV), and ternary alloys NbTaV ordered in body-centered-cubic (BCC) structures with 128 Bravais lattice sites. The first-principles code used to run the calculations is the Vienna Ab-Initio Simulation Package. The calculations have been collected by uniformly sampling chemical compositions across the entire compositional range. For each chemical composition, the calculations have been run for 100 randomized arrangements of the constituents on the BCC lattice sites. This sampling methodology resulted in running DFT simulations for a total of 3,100 randomized atomic configurations over 31 chemical compositions for each of the three binary alloys Nb-Ta, Nb-V, Ta-V, and a total of 10,500 randomized atomic structures over 105 chemical compositions for the ternary alloys Nb-Ta-V. For each atomic configuration, geometry optimization has been performed, and the data released contains information about each step of geometry optimization for each atomic configuration.
CdS Quantum Dot Gels as a Direct Hydrogen Atom Transfer Photocatalyst for C-H Functionalization
Authors: Liu Daohua , Hazra Atanu , Liu Xiaolong , Maity Rajendra , Tan Ting , Luo Long
Published: February 2024

Here, we report CdS quantum dot (QD) gels, a three-dimensional network of interconnected CdS QDs, as a new type of direct hydrogen atom transfer (d-HAT) photocatalyst for C-H functionalization. We discovered that the photoexcited CdS QD gel could generate various neutral radicals, including α-amido, heterocyclic, acyl, and benzylic radicals, from their correspond-ing stable molecular substrates, including amides, thio/ethers, aldehydes, and benzylic compounds. Its C-H activation ability imparts a broad substrate and reaction scope. The mechanistic study reveals that this reactivity is intrinsic to CdS materials, and the neutral radical generation did not proceed via the conventional sequential electron transfer and proton transfer pathway. Instead, the C-H bonds are activated by the photoexcited CdS QD gel via a d-HAT mechanism. This d-HAT mechanism is supported by the linear correlation between the logarithm of the C-H bond activation rate constant and the C-H bond dissociation energy with a Brønsted slope α = 0.5. Our findings expand the currently limited direct hydrogen atom transfer photocatalysis toolbox and provide new possibilities for photocatalytic C-H functionalization.

Problems affecting the foundation of a bridge are always difficult to see because the structure is on the ground or covered by water flow. Scouring around piers and abutments can lead to unpredictable consequences that can result in sudden collapse of the structure. In this paper, the effect of foundation stiffness (before and after the bridge repair works} on the dynamic response of the bridge structure is investigated. The results will help to diagnose the bridge foundation in the future. Based on the results of span monitoring before and after repair works combined with numerical model analysis on a bridge in Vietnam, the effects of scouring at the bridge piers are determined. The research results reveal that the dynamic responses of the structure make it possible to detect damage to the foundation and determine whether scour is likely to occur in the vicinity of the bridge foundations.

Medium composition affects the productivity of oyster mushroom. Nutritious ingredient may increase the mushroom productivity. Peanut shell as a leguminous plant is rich in protein content than zea mays bran a common supplement for the medium. This research ach aims to see the influence of peanut shell supplementation at different concentration on productivity of oyster mushroom in comparison to zea mays bran. The concentration used were 0; 3 and 6% of peanut shell or zea mays bran. The parameter observed were the time of primordial pin head appearance; the pin head number, fresh weigh and dry weight of oyster mushroom. The data obtained were analyzed using ONE WAY ANOVA followed by Least Significant Different Test for the significance. The result showed that medium with Zea mays did not show a significant different from control in all parameters used. The peanut shell increased the dray weight of oyster mushroom, the dray weight increase was higher at supplementation of 3% peanut shell than that of 6%. The fresh weight and number fruiting body were not significantly different among all the treatments, however, the average of the fresh weigh and the number of pin-head, were higher found on medium supplemented with peanut shell that others. Three percentage of peanut shell was better than that of 6%.

Lisong tuna (Auxis rochei) is one of high economic potential value of fish because of its abundance and often found in the fish market in Ampenan. Evaluating the impact of fishing to the growth pattern of length-weight of tuna is needed to ensure the sustainability of lisong tuna population. It is feared that the high intensity of tuna (A. rochei) fishing can cause growth disturbances and a decrease in local tuna populations. This study aimed to determine the relationship between the weight and length of lisong tuna (A. rochei) to their growth patterns in the fish market of Ampenan. Thirty individuals of lisong tuna were collected from two fish markets, Bintaro and Kebon Roek, in Ampenan. The equation of Linear Allometric Model is used to evaluate the length and weight relationship in growth patterns of lisong tuna. This study resulted in the positive allometric growth pattern of lisong tuna with slope value more than 3 (b=3.79). It indicated that the lisong tuna which were collected in Bintaro and Kebon Roek markets have a weight growth rate faster than their length growth rate. It means that the lisong tuna sold in Ampenan markets is quite fleshy and has a good growth rate.

Banana peel waste is one of the contributors to organic waste in Indonesia. By using banana peels as fertilizer, it is hoped that organic waste can be reduced. This research aims to determine the effect of Liquid Organic Fertilizer (LOF) from kepok banana peel (Musa acuminata) on the growth of mustard greens (Brassica juncea), using an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments with 4 replications, namely P0: control group (without banana peel waste LOF), P1 = 25 ml LOF, P2 = 50 ml LOF, P3 = 75 ml LOF, and P4 = 100 ml LOF. The parameters observed were plant height, number of leaves, and wet weight. The research data were analyzed using the ANOVA test with a significance level of 5% followed by the DMRT/Duncan test to determine the differences in effects between treatments. Giving 75 ml of banana peel LOF had the most effective effect with an average plant height of 16.75 cm, an average number of leaves of 7, and an average wet weight of 2.25 gr. From the results of the ANOVA test, the plant height was 7.95, the number of leaves was 1.17, and the wet weight was 16.00. From the three parameters, it was found that Fcount>Ftable (2.87) so it was concluded that giving 75 ml LOF of kepok banana peel had a significant effect on the vegetative growth of mustard plants compared to other treatments, especially on the parameters of plant height and fresh weight.
