Authors: Anjani Imas Galuh , Suhartanto Muhammad Rahmad , Purwito Agus
Published: October 2023

Penurunan mutu benih atau deteriorasi merupakan salah satu penghambat dalam produksi benih jagung dan umumnya terjadi selama penyimpanan benih yang ditandai dengan turunnya viabilitas dan vigor benih sehingga mengakibatkan jeleknya pertanaman serta menurunnya hasil. Pengusangan cepat secara kimia merupakan salah satu metode yang digunakan untuk mengetahui percepatan penurunan kualitas benih dengan memanfaatkan kinerja uap etanol. Pengusangan ini dilakukan oleh APC IPB 77-1 MM yang berfungsi melakukan devigorasi benih baik secara fisik dengan uap panas maupun secara kimia dengan etanol. Hasil dari pengujian ini akan digunakan untuk menduga vigor daya simpan (VDS) benih jagung sehingga pemanfaatan dan pengolahan benih jagung dapat dilakukan secara efektif dan efisien. Penelitian dilaksanakan di Laboratorium Biologi dan Biofisika Benih, Laboratorium Penyimpanan dan Pengujian Mutu Benih, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, Institut Pertanian Bogor dari bulan Maret 2019 hingga Agustus 2019. Penelitian ini terdiri dari dua percobaan. Percobaan pertama yaitu metode pengusangan dengan menyimpan benih pada kelembaban 98% dan suhu 40 oC selama 10 hari. Rancangan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) dengan satu faktor yaitu varietas jagung. Percobaan kedua yaitu pengusangan cepat benih jagung secara kimia dengan etanol 96% menggunakan APC IPB 77-1 MM. Rancangan yang digunakan adalah RKLT satu faktor varietas jagung. Hasil percobaan menunjukkan alat pengusangan cepat IPB 77-1 MM dapat digunakan untuk menduga penurunan vigor daya simpan pada benih jagung. Pengujian pengusangan cepat secara kimiawi lebih efektif dan efisien dalam menentukan nilai vigor daya simpan karena membutuhkan waktu yang relatif lebih singkat. Hasil perbandingan secara deskriptif menunjukkan bahwa APC IPB 77-1 MM dapat menunjukkan urutan nilai vigor daya simpan benih kelima varietas jagung yang sama dengan percobaan pengusangan dengan metode penyimpanan pada suhu dan kelembaban tinggi.

Este trabalho delimitou como objetivo realizar uma investigação discursiva sobre os impactos do exercício
físico nas dimensões humanas e os benefícios que ele causa ao ser humano. Para tanto, recorremos aos
pressupostos teórico-metodológicos clássicos de Böhme (1993), Guedes e Guedes (1995), Guimarães (1996),
Daolio (2003) e Medina (1986), configurando assim uma pesquisa exploratória, de cunho bibliográfico e
caráter qualitativo. Inicialmente, realizamos um trajeto histórico em que explicitamos desde uma prática
segregadora a uma proposta de Educação Física holística. Depois, discutimos sobre as multidimensões
humanas e sua importância para integralidade do ser humano. Na terceira seção, analisamos os impactos dos
exercícios físicos nas dimensões humanas. Em conclusão, apontamos que, quando os exercícios físicos
priorizam um trabalho que interaja com as dimensões humanas, a partir de preceitos holísticos, contemplase o ser biopsicossocioespiritualmente, agregando benefícios à vida humana em sociedade.

Authors: Bogado Vera Ovidio Javier
Published: October 2023

El Ministerio de Transporte de Argentina emitió la Resolución N° 625/2022 que establece un costo de peaje para el uso del tramo de navegación sobre la Hidrovía Paraguay-Paraná. El análisis -síntesis normativo, ambiental y de la comisión de la HPP, se realiza basado en el principio jurídico “Ley superior deroga a la Ley inferior” confrontada con el Acuerdo de Santa Cruz de la Sierra, y la Constitución Nacional de la República Argentina. Como resultado se afirma la existencia de antinomia por violar del principio de jerarquía de la norma, pues conforme a la Constitución Argentina y el Acuerdo de Santa Cruz de la Sierra, la Resolución N° 625/22 es inaplicable, además no contempla factores del medio ambiente, ni de la Comisión HPP relacionadas sobre el funcionamiento y gestión. Respecto a la conclusión, se recomienda que Paraguay recurra y aplique el artículo 26 sobre solución de controversia con motivo de la interpretación, aplicación o incumplimiento de las disposiciones del presente acuerdo, para lo cual se sugiere la utilización previamente de los medios alternativos de solución de conflictos “LA MEDIACIÓN VÍA CANCILLERÍA ANTES DEL ARBRITRAJE”. En búsqueda de una salida aceptable para ambas naciones sería la decisión más prudente, pues permitirá mantener el control del proceso para ambas partes del conflicto.

Time series forecasting of precipitation patterns over Lucknow region using LSTM
Authors: Devasheesh Krishan  , Amrendra Singh
Published: October 2023

Rainfall forecasting has assumed an important role in recent times due to uncertainities emanating from climate change as a result of environmental phenomenons like El Nino, La Nina, global warming, etc. Agriculture in India is still pretty much dependent upon rains, more so in a state like Uttar Pradesh. So it is imperative that forecasting systems are developed that can analyse the previous trends of rainfall and predict accordingly the future values of rain. The existing statistical models that forecast rain are too complex and also not cost effective. Hence we take the approach of a machine learning model, or to further specify, a deep learning model called Long Short Term Memory (LSTM) to try and predict with some accuracy. This study examines the precipitation patterns over the Lucknow region for a period of 20 years, with the dates ranging from 1st January, 2000 to 31st December, 2019. The accuracy of the LSTM model developed is judged on the basis of Mean Absolute Percentage Error (MAPE), R-square (R2) and Root Mean Squared Error (RMSE) values.

Aedes aegypti mosquito is a vector for Dengue Hemorrhagic Fever. One effort to prevent the spread of the disease is vector control. The use of insecticides is a form of vector control in an effort to control DHF. There are two broad categories of insecticides that are often used as household insecticides, namely insecticides that function to kill insects and insecticides that function to repel insects. Kedondong (Spondias pinnata) which is a family of anacardiaceae which generally grows well in tropical climates. Kedondong bark contains saponins, alkaloids, and flavonoids which are secondary metabolites involved in defense mechanisms against attack by many microorganisms. This study aims to determine the biolarvicidal activity of the ethanol extract of kedondong stem bark in killing Aedes aegypti mosquito larvae. This study used 5 treatments and 3 replications. Each treatment contained 20 Aedes aegypti mosquito larvae. Observations were made for 24 hours with observation times of 0 hours, 6 hours, 12 hours, 18 hours and 24 hours. The time calculation starts after the larvae are inserted into the experimental bottle. The results showed that kedondong bark extract was able to kill Aedes aegypti mosquito larvae. The effective dose of ethanol extract of kedondong stem bark in killing Aedes aegypti mosquito larvae is 20 mg/mL.

Authors: Hitijahubessy Hendro
Published: October 2023

The activated carbon made in this study is activated carbon in the form of powder and granules (a mixture of the two) by a chemical activation process using calcium oxide (CaO). The characterization of activated carbon refers to the Indonesian National Standard 06-3730-1995 concerning technical activated carbon with the indicators tested being moisture content, volatile matter content, total ash content, bound carbon content and iodine adsorption capacity. Based on research on the characterization of activated carbon, nutmeg shells have a moisture content of 0.6979 %, volatile matter content of 3.8781%, total ash content of 8.7323%, bound carbon content of 87.3896 % and iodine adsorption capacity of 325. 0694 mg/g. Iodine adsorption capacity aims to determine the adsorption capacity of activated carbon. Based on the technical quality standard of activated carbon regarding iodine adsorption capacity stipulated by SNI 06-3730-1995, researchers can explain that the pore capacity of nutmeg shell activated carbon is very good for use as an adsorbent. The important use of activated carbon in nutmeg shells as an adsorbent is expected to be utilized for water purification from bacteria, absorption of inorganic materials dissolved in water and cosmetic base ingredients.

Authors: Laratmase Nia , Nindatu Maria
Published: October 2023

This research is laboratory experimental in nature and was analyzed using Analysis of Variance and continued with Duncan's test, with 95% confidence (α=0.05) using SAS software. The results showed that giving clove leaf steeping could reduce uric acid levels in the blood of Rattus norvegicus rats. Clove leaf infusion (Syzygium aromaticum L.) contains flavonoids which have xanthine oxidase inhibitory activity, including luteolin, apigenin, kaemferol, and quercetin. In addition, Vitamin C can reduce oxidative stress and inflammation which affect the decrease in uric acid synthesis. Other compounds, namely tannins, alkaloids, and saponins have the same role as flavonoids, namely reducing the activity of the enzyme xanthine oxidase in serum and increasing the concentration of uric acid in the urine, as well as binding free radicals during the conversion of purines into uric acid. Infusion of clove leaves doses of 0.09g, 0.18g and 0.36g can reduce uric acid levels in the blood of rats (Rattus norvegicus) with an effective dose of 0.36g.

Published: October 2023

Processing of black cassava has the possibility of microbial contamination because the fermentation process is carried out in the open, black cassava in the open, at room temperature, allowing microbes such as bacteria to grow. The aim of this research is to determine the length of time for boiling cassava and the presence of bacteria, and to determine the appropriate boiling time that can inhibit the presence of bacteria. From the results of observations of cassava samples containing bacteria before boiling, this shows that fresh cassava used as raw material naturally contains a number of bacteria. Observing the colony characteristics of all bacterial isolates counted and uncounted, it was found that there were similarities and differences in properties, where the results of the analysis showed that the long boiling time treatment had a great influence on the morphology of the bacteria, namely round and wrinkled, with smooth and grooved edges, raised elevations, flat and thick. The color of the bacteria on black cassava is the same, namely white, with treatment times of 10, 20, 30 minutes. The boiling time treatment has a very significant effect on the shape, edges and elevation in the presence of bacteria. The presence of bacteria in black cassava before boiling shows that it naturally contains a number of bacteria, with long boiling treatment the number of bacteria increases.

One of the waste that is often found is organic waste. The existence of this waste needs to be handled so that it does not pollute the environment and has more use value. Through proper processing, organic waste can be used as organic fertilizer and biogas. One of the techniques used for this processing is to use the submarine bioreactor technique. This study aims to explore the processing of organic waste in Ngemplak Kidul Margoyoso Pati Village using the submarine bioreactor technique. This research is a field research with a qualitative approach and then analyzed descriptively. The stages of processing organic waste with the submarine bioreactor technique are enumeration, then the stage of producing decomposers, the stage of producing fertilizer and the stage of producing biogas. The advantage of this submarine bioreactor technique is that if a leak occurs it can be detected and can distribute gas over long distances and is safe in its use. Even though it takes a long time and costs a lot, this bioreactor is proven to be able to produce effective fertilizer and biogas for large quantities of plants. After this research, it is hoped that it will provide an overview of waste processing using the submarine bioreactor technique and can become a reference for village governments or other institutions to implement in their area as a solution for organic waste processing.

Gandaria leaves (Boea macrophylla Griff) have potential as antibacterial. The ability to inhibit bacterial growth is inseparable from the role of active compounds, namely flavonoids, tannins, quinones and triterpenoids. Growth by microbes needs to be controlled, namely by inhibiting microorganisms, one way is by using chemicals, namely antiseptics. This study aims to determine the effectiveness of antiseptics made from gandaria leaves against the growth of S. aureus and E. coli bacteria. The concentrations of the ethanol extract of gandaria leaves used were 5%, 15% and 25% and betadine (+) and aquades (-) were used as controls. Antiseptic effectiveness test against S. aureus and E. coli bacteria using disc diffusion method. The test results showed that the antiseptic based on gandaria leaves had the ability to inhibit the growth of S. aureus with a concentration of 15% at 2.00 mm and 25% at 4.00 mm. Meanwhile, for E. coli bacteria, antiseptic made from gandaria leaves has an inhibition zone at a concentration of 15% at 1.00 mm. In accordance with the criteria for antiseptic power according to Davis Stout, gandaria leaves which are used as basic ingredients for antiseptics are included in the criteria for very weak antiseptic power (≤5). Therefore, the antiseptic based on gandaria leaves in this study was less effective in inhibiting the growth of S. aureus and E. coli bacteria.
