Published: November 2022

Banjir merupakan kondisi dimana air tidak dapat ditampung di sebuah saluran atau sumbatan aliran air di saluran pembuangan. Tingginya curah hujan dan disertai perubahan sIstem tataguna lahan dapat meningkatkan permukaan air limpasan yang mengalir dengan cepat, sehingga menyebabkan banjir. Daerah Aliran Sungai (DAS) Jeroan, termasuk dalam wilayah Kabupaten Madiun, Provinsi Jawa Timur. Sungai Jeroan merupakan anak dari Sungai Bengawan Solo, hulu Sungai Jeroan terletak di Kecamatan Saradan dan hilirnya terletak di Desa Balerejo, yang bertemu dengan Sungai Bengawan Solo. Panjang Sungai Jeroan ± 34,84 km dan mempunyai luas DAS 314,34 km2. Debit yang dapat ditampung sungai adalah sebesar 179,73 m3/dt. Selanjutnya direncanakan normalisasi, sepanjang STA 276–232 dengan b = 15 m, h = 8 m dan m = 1 serta normalisasi sepanjang STA 228–0 dengan b = 20 m, h = 8 m dan m = 1 dengan debit yang mampu ditampung sungai sebesar 226,82 m3/dt. Setelah dilakukan normalisasi, debit yang melewati sungai tersebut masih belum tertampung seluruhnya ke dalam sungai, berdasarkan perhitungan dengan menggunakan metode HSS Nakayashu, didapatkan debit dengan kala ulang 25 tahun sebesar 461,20 m3 untuk DAS Jeroan. Selanjutnya dilakukan penanganan dengan 2 buah kolam retensi, direncanakan kolam retensi dengan kapasitas sebesar 839.310,12 m3 untuk kolam retensi 1 dan 535.096,03 m3 untuk kolam retensi 2, dengan luas area kolam retensi sebesar 111.908 m2 untuk kolam retensi 1 dan 76.442 m2 untuk kolam retensi 2. Sedangkan untuk pintu air yang direncanakan menggunakan pintu bendung sebanyak 2-unit pada tiap kolam retensi dengan debit yang tereduksi dengan penanganan kolam retensi adalah sebesar 80,16 m3/dt atau sekitar 17%.

Serbuk hasil isolasi diidentifikasi rendemennya, diukur densitasnya, analisis gugus fungsi yang terbentuk dengan FTIR, dan menghitung kemampuan dalam mengadsorbsi zat warna metilen blue dengan Uv-Vis. Hasil penelitian menunjukkan bahwa kitosan yang dihasilkan berbentuk serbuk berwarna putih keabuan, rendemen 33,71%, densitas curah kitosan sebesar 1,21 gr/, serta didapat derajat deasetilasi dari kitosan sebesar 57,50 %. Efisiensi penyerapan zat warna Metilen biru oleh kitosan di setiap konsentrasi rata-rata bernilai 90 %. Oleh karena itu, biopolimer kitosansangat efektif dalam mengadsorbsi zat warna metilen blue. Kata kunci: deasetilasi bertahap; efisiensi penyerapan; karakteristik kitosan. ABSTRACTChitosan biopolymer has many applications including as a biosorbent, scaffold, fish preservative, and antimicrobial in food. In several studies, chitosan was very effective in adsorption of methylene blue dye ions. The purpose of this study was to identify the characteristics of chitosan isolated from pearl shells. The process of isolation of chitosan biopolymer uses the stepwise deacetylation method. Where the isolation process is carried out by three processes, namely deproteination, demineralization, and deacetylation. The isolated powder was identified its yield, measured its density, analyzed the functional groups formed by FTIR, and calculated the ability to adsorb methylene blue dye with UV-Vis. The results show that the chitosan is a grayish-white powder, the yield is 33.71%, the bulk density of chitosan is 1.21 gr/cm3, and the degree of deacetylation of chitosan is 57.50%. The absorption efficiency of methylene blue dye by chitosan at each concentration averaged 90%. Therefore, chitosan biopolymer is very effective in adsorbing methylene blue dye.

Directions for improvement of the herbicide assortment in Russia at the beginning of the 21st century
Authors: Golubev A. S. 
Published: November 2022

Changes in herbicides recommended for the use in Russian Federation between 2000 and 2022 are analyzed. The main
directions of iimproving chemical control of weeds are identified based on the integration of domestic market with the world
market. Only a limited number of active ingredients was introduced in Russia during the last decade, including pinoxaden,
thiencarbazone-methyl, piroxulam, sodium flucarbazone, topramezone, diclosulam, tembotrione, and metamifop.
Improved formulations of herbicides such as colloidal solution concentrate with increased penetrability due to the particle
size reduced by an order of magnitude became widely available. Premix herbicides were developed based on tribenuronmethyl, metsulfuron-methyl, florasulam, clopiralid, picloram, imazamox, imazapyr, imazethapyr, etc.Parameters for
herbicide application were optimized to consider phenology of weeds. Novel technologies were implemented, such as
growing hybrids resistant to certain active ingredients to allow their application during crop vegetation.

Authors: López Cárcamo Brenda Regina 
Published: November 2022

Introducción: Las Buenas Prácticas de manufactura-BPM- tienen relevancia al momento de seleccionar las materias primas para la preparación de alimentos; además considerando que el que manipula los alimentos debe estar muy bien capacitado para seleccionar dichas materias primas y con ello evitar la contaminación alimentaria; por ello este artículo permitirá indicar si en los establecimientos de una Universidad Pública logran evitar la contaminación alimentaria. Objetivos: El objetivo de este artículo es demostrar y contribuir que las muestras de alimentos obtenidas en establecimientos de alimentos cumplen con inocuidad alimentaria y por otro lado se pretende comparar e interpretar que, si hay microorganismos frecuentes, estos pueden ser aislados de los alimentos obtenidos de establecimientos de alimentos, pero que con capacitación en buenas prácticas de manufactura logren mejorar la selección de materias primas. Metodología: Se consideró 455 resultados obtenidos en el laboratorio de control microbiológico de alimentos, de la Universidad Pública de Guatemala y se les realizó el análisis frecuente de indicador de contaminación fecal, la cual es la Escherichia coli; posteriormente se realizó un segundo vigilancia de microorganismos patógenos presentes en los alimentos, a los cuales a más de un alimento se le realizó dos o más patógenos, según el alimento procesado y con ello compararlo a los valores de aceptabilidad del Reglamento Centroamericano-RTCA-. Por último, se realizaron 18 capacitaciones de -BPM-; por último, para su análisis se aplicó el programa de Excel para la Interpretación de resultados. Resultados: De las 455 muestras analizadas tuvieron Escherichia coli como indicador de contaminación fecal; por lo que se llevó a cabo un segundo muestreo para determinar microorganismos patógenos indicando que fueron 215 alimentos y se realizó de un mismo alimento, entre 1 y 3 patógenos más frecuentes que se concentran en dicha materia prima; para lo cual fue un total de 600 análisis microbiológicos; de dichos resultados se presentaron dentro de un rango fuera del parámetro de aceptabilidad, el 14.12 % (12) presentó Grupo Coliforme, 98.82 % (84) E. coli, 96.49 % (110) Mohos y levaduras y 75 % (78) Recuento Aeróbico Total. Conclusiones: Se debe implementar en los establecimientos Buenas Prácticas de Manufactura -BPM-, así como mínimo capacitar dos veces al año a los manipuladores; con el fin de lograr incrementar la higiene e inocuidad alimentaria y con ello mantener los límites de inocuidad alimentaria en dichos establecimientos.

Local chicken is one of the Indonesia native chickens that potential to be developed. It could be found in all the provinces from the city to the rural area though have the various weather and climate condition. Feed as one of the three main factors in animal field affect the improvement of animal production in fulfilling the animal protein needs of human. One of the alternatives to eliminate feed cost is utilizing local resources as protein sources for animal by using sea remis flour. This study aimed to understand the effectivity of sea remis flour addition on local chicken productivity. Research method used was completely randomized design consists of 4 treatments and 5 replications by using 40 laying phase local chickens raised intensively for 32 days in battery cages filled 2 chickens per cage unit. Treatment rations were concentrate substitution toward 0% of sea remis flour (R0), concentrate substitution toward 1.5 % of sea remis flour (R1), concentrate substitution toward 3% of sea remis flour (R2), concentrate substitution toward 4.5% of sea remis flour (R3). Based on result of the study, it could be stated that addition of 3% of sea remis flour in ration affect feed consumption, egg production, feed conversion, and egg weight.
