OPTIMASI KAPASITAS PRODUKSI UKM DENGAN GOAL PROGRAMMING
Authors: Sugianto Welly 
Published: May 2020

UKM Jovelyn is a small medium enterprise (SME) that engaged in the field of bakery production. Until now, they produce cakes and cookies. They sell products throughout the Batam area which includes (Tiban market, aviari market, mitra market and puja bahari market), shops, school canteens and so on. The SME targets several things such as profit per month, number of hours worked, number of overtime hours, machine utilities, labor utilities and so forth. Until now, the SME has not been able to reach the targets because the UKM has not determined the production amount based on the appropriate calculation. The number of products made is determined only on an intuitive basis. Determination of the amount of production cannot be determined by the usual simplex method because the objective function in the usual simplex method contains a target. Problem solving is done by using goal programming. The results of the calculation analysis show that to achieve the optimal value, the SME must produce coconut root cookies, butter cookies, nastar cookies, snow princess cookies and peanut cookies respectively 11.89 kg, 22.43 kg, 24.96 kg , 1.97kg and 0 kg. Sensitivity analysis is carried out after there are changes in conditions that result in changes in the linear program matrix, so the number of products that must be made also changes which include coconut root cookies as much as 12.8 kg, as much as 16.91 kg of butter cookies, nastar cookies as much as 25.7 and the last is 3.39 kg of nut cookies which in the initial calculation, nut cookies were not produced. The sensitivity analysis is not done by recalculation but rather by modifying the matrix and completing iteration with primal dual.

Bu araştırma, imam hatip lisesi öğrencilerinin bu okulları tercih sebepleri, hedefleri, okullarından beklentileri ve memnuniyetleri ile öğrenci ve imam hatip lisesi mezunlarının çeşitli konulardaki görüşlerini belirlemek amacıyla karma yöntemle yürütülmüştür. Araştırmada İmam Hatip Lisesi Öğrencilerinin Bu Okulları Tercih Nedenleri, Okuldan Beklentileri ve Memnuniyetleri Anketi, İmam Hatip Lisesi Öğrencilerinin Çeşitli Konulardaki Görüşleri Görüşme Formu ve İmam Hatip Lisesi Mezunlarına Göre İmam Hatip Liselerinin Dünü, Bugünü ve Yarını Anketi olmak üzere üç farklı veri toplama aracı öğrenci ve mezunlardan oluşan üç farklı çalışma grubuna uygulanmıştır. Verilerin analizinde frekans, ortalama ve yüzdelik gibi nicel betimsel analizler ile içerik analizi kullanılmıştır. 2017-2018 eğitim-öğretim yılında yürütülen araştırmanın sonuçlarına göre, öğrenciler imam hatip liselerini ailelerinin yönlendirmesi neticesinde tercih etmişlerdir. Bunun yanında, imam hatip liselerini tercih sebeplerine, istediği okula yerleşememe olarak ifade edilebilecek bir sebep eklenmiştir. Öğrencilerin beklentileri dinî bilgileri edinmeye yöneliktir. Aldığı eğitim sonrasında din görevlisi/ilahiyatçı olmak isteyen öğrenciler ise azınlıkta kalmıştır. Eğitim-öğretimin kalitesinin artırılması gerektiğini belirten öğrenciler, imkânları olsa bu okulu tercih etmeyeceklerini ve yönetim uygulamalarında çeşitli değişiklikler olması gerektiğini belirtmişlerdir. Öğrencilerin imam hatip lisesinde okumayı dinî/millî/manevî değerler çerçevesinde ifade ettikleri görülmüştür. Öğrenciler, imam hatip liselerinin dinî eğitim görmek anlamına geldiğini düşünmektedir. İmam hatipli olduklarını toplum içerisinde ifade edebildiklerini belirten öğrenciler, toplumun kendilerinden beklentilerinin olumlu yönde olduğunu düşünmekte, dinî/millî/manevî değerleri temsil eden şahsiyetleri örnek/rehber olarak görmektedirler. Onlara göre, dünya sorunları içerisinde çözülmesi gereken öncelikli sorunlar dinî/ahlâkî sorunlar ile insanî sorunlardır. Mezunların kendi öğrencilik dönemlerini olumlu kavramlarla, günümüzü ise daha olumsuz kavramlarla ifade ettikleri, geleceğe dair daha ümitli oldukları görülmektedir.

Measures of weed control by means of environmentally friendly technologies in summer-autumn period
Authors: Kurdiukova O. , Tyshchuk O. 
Published: May 2020

Goal. To select criteria for optimal solutions for calculating techniques of effective control of weeds in the summer-autumn period, taking into account their biological groups, the level of weed infestation and harmfulness.
Methods. The experiments were carried out in a stationary field crop rotation, laid down in 2010. Carrying out the experiment and determining weed infestation was performed according to generally accepted methods. To process data and criteria for optimal combinations of weed control methods, the calculation method was used.
Results. The essence of the optimal solution for controlling weeds in the summer-autumn period is as follows. The period of time, during which effective control of weeds can be carried out is determined. This is the period from harvesting the crop to the end of the weed growing season. The number of possible agro-technical technique of control is taken into account. It is assumed that for the emergence of annual seedlings or the restoration of the organs of vegetative propagation of perennial weeds, an average of 15 days is required. The possible harm in the given field of various biological groups of weeds is calculated in points by multiplying the actual weed infestation in points by the value of their harmfulness by rank. A table is compiled of the ranks of the effectiveness of agro-technical control techniques for each biological group of weeds. The most effective individual weed control techniques or their combination are selected. Each technique or combination thereof is evaluated and summing up the results; effective methods for controlling weeds are determined by indicators of the least residual damage. In order to determine the reasonability of increasing the number of agricultural practices, the conditional weed harm score is calculated by dividing the sum of the results by the square of the number of techniques. A decrease in the conditional score with an increase in the number of agro-technical measures shows that a further increase in the number of weed control methods is impractical.
Conclusions. In the system of ecologically safe farming, the main attention in the weed control system belongs to summer-autumn agro-technical techniques. Calculation of such weed control in specific soil and climatic conditions can significantly increase the effectiveness of both individual agricultural methods and their combinations.

Authors: Nychkaliuk G. 
Published: May 2020

Goal. Paulownia felines — Paulownia tomentosa L., a promising bioenergy crop for our country. In the early stages of organogenesis (juvenile and immature), young plants of the peacock sprout easily suppress weeds. Therefore, young plantations of such a promising bioenergy crop need reliable and effective protection against the adverse effects of weeds. Method. Weeding processes for young peacock plantations in the small field experiments were conducted in 2018—2019. on the experimental lands of the Yaltushk SSS IBEK and the Central Bank of NAAS The area of the plots is 36 m2, the area of the plot is 25 m2. Repeat studies — 4 times. Placement of sites is regular in two tiers. Seeds and young plants (seedlings) of Clone 112 were used for growing on the plots. Results and Discussion. Contamination of plantations was mixed. The records, carried out on 01.06, recorded the presence of seedlings of Echinochloa crus-galli (L.) Pal Beauv, Setaria glauca (L.) Pal.Beauv, Chenopodium album L., Sinapis arvensis L., Thlaspy arvense L., Polygonum scabrum Moench., mustard beetle, Polygonum convolvulus L, Solanum nigrum L. The number of weeds averaged 89.5 pcs/m2. The largest number of seedlings was recorded in millet rooster 12.4pcs/m2, mouse gray — 10.3 pcs/m2, white swans — 8.7 pcs/m2, bear­ded birch — 7.3 pcs/ m2, talaban field — 7.1 pcs/m2. By the third decade of August, their number had increased to 134.0 pieces/ m2. Conclusions. Under the conditions of co-vegetation of young peacock-planted plants with weeds, the height of their plants by the second decade of September averaged 23.6.cm. The height of crop plants that vegetated without adversely affecting the presence of weed plantations (4 consecutive manual weeding) averaged 63.8 cm or 2.7 times greater. Such a negative impact requires the implementation of protection measures for young plants.

Authors: Makuch Y. , Moshkivska S. , Smih V. 
Published: May 2020

Goal. Search and evaluate the effectiveness of herbicides and their compositions in chickpea crops. On the basis of research to prepare a comprehensive system of protection of chickpea crops from the presence of weeds, which ensures high yields and is economically and environmentally feasible in the conditions of the Right-bank Forest-Steppe of Ukraine.
Methods. The experiments were based on the following scheme: Factor A (weed protection): 1. Net control; 2. Harsh control; 3. Fabian, D.Sc. 0.1 kg/ha; 4. Bazagran, bp — 2.5 l/ha; 5. Reiser, k.e. 2.0 l/ha. Factor B (seeding rate): Seeding rate, thousand pieces / ha —500; 600; 700.
Results. One way to increase the competition of chickpea plants with weeds can be to increase the stocking density of cultivated plants. It is also known that the combination of several methods of crop care contributes to the overall increase of their effect. By identifying a critical period of competitive interaction between chickpeas and weeds, it is possible to take action on the latter before they cause significant damage to the crop. Competitive reciprocity and harmfulness of weeds in chickpea crops is observed throughout the entire period of crop development. A significant decrease in productivity is observed in the presence of 10 weed plants per square meter. Increased weed density of up to 25 pc/m2 showed a 23.7% decrease in crop yield.
Conclusions. On the basis of the conducted researches it is possible to make a generalization that in the conditions of humus soils of the Right-Bank Forest-Steppe of Ukraine, when applying herbicides on chickpea crops, the best results in weed control were obtained with the introduction of Fabian, dr. application rate of 0.1 kg/ha and Bazagran, pp. 2.5 l/ha.

Published: May 2020

Goal. Is to determine the species composition of weeds in Miscanthus giganteus plantings, their impact on biomass productivity and the development of an effective protection system. Methods. Field experiments, laboratory agrochemical studies, mathematical and statistical — to evaluate the reliability of the obtained data. Results. At the beginning of the first year of vegetation in the miscanthus crops, the type of weed was mixed, with a large predominance of annual monocotyledonous species 91.1—93.6%. But in the second (70.1—85.3%) and the third (51.1—79.8%) years of vegetation, dicotyledonous species prevailed, while in the fourth, the monocotyledonous species (55.6—64.8%) had a slight advantage. In the first year of vegetation the weed was quite high and amounted to 1156 p./m2, in the second year — 873 p./m2, it decreased to 380—386 p./ m2. On the variants of application of herbicides for the second and next years, a decrease in the number of weeds by 41.3—64.5% compared with the weed pollution control and depending on the year of vegetation was observed. In the conditions of co-vegetation of weed plants with the weeds, the largest mass was formed by the Chenopodium album L. (930 g/m2 in the first year and 93 g/ m2 in the fourth year), Amaranthus retroflexus L. (455 g/ m2 and 60.6 g/ m2), Artemisia annua L. (280 g/m2 and 29.1 g/m2) and annual monocotyledonous Echinochloa crus-galli (L.) Pal. Beauv. (225 g/ m2 and 17 g/ m2) and Setaria glauca (L.) Pal. Beauv (360 g/ m2 and 15.4 g/ m2). Weed pollution control on miscanthus crops helped to increase the biomass yield in the first year of vegetation to 2.6—2.7 t/ha of wet weight, to the fourth — up to 36.3—37.4 t/ ha. In the Weed pollution control, only 0.5 t/ha were obtained in the first year of vegetation, while in the fourth year it was 22.1 t/ ha. Conclusions. A mixed type of weed was found on the landing of Miscanthus giganteus, with 19 species from 12 families. Application of herbicides Task Extra and Master Power weed pollution reduction by 83.3—99.2%, which made it possible to improve the conditions of growing and development of Miscanthus giganteus plants and to obtain a dry biomass yield of 20.0 t/ha for the fourth year of vegetation.
