Climate change: challenges and limitations in agriculture
Authors: Keutgen A J 
Published: June 2023

Abstract
Climate has always been changing, but the current changes and climate models indicate a significant and rapid increase of temperatures, atmospheric CO2 concentration, shifts in precipitation patterns and consequently a higher frequency, duration and intensity of climate extremes (frost, heat and drought periods, heavy precipitation, hail, storms, floods, storm surges, etc.). Thus, agriculture on the whole but also agro-ecosystems are very susceptible and highly vulnerable to the effects of these changes. The scenarios for climate development in Austria also follow the global trends. Increasing temperatures in combination with more frequent heat waves, water shortage and drought events will be the most serious constraints on growth and quality of many crop plants. However, such changes do not result only in the negative effects. Higher average temperatures accelerate the development of many plants. The increasing CO2 concentration in the atmosphere to a certain extent may stimulate plant growth (fertilization effect) combined with an increased water use efficiency. The cultivation period is longer and the winters milder and wetter, which may allow new cultivation time and forms as well as new species. For agriculture, several adaptive strategies are possible, which include but are not limited to plant breeding, choice of plant species and variety as well as soil and cultivation management. However, the extent to which negative and positive climate impacts will strongly influence the agriculture in the given area is still largely unknown, but will be of crucial importance for the prediction of future crop yields.

Abstract
Pakchoy (Brassica chinensis L. or Brassica rapa subsp. chinensis) experienced a decreased production and productivity. Sustainable agriculture could be the solution using organic fertilizer cow manure and biofrtilizer Bio-ekstrim. The objective of this research was to determinine the contribution of the effect of manure of cow and bio-extrim and their interaction on the performance of Pakchoy. A factorial randomized complete block design with three replications was used at the experimental garden of Agriculture Faculty of Universitas HKBP Nommensen in Medan. Pakchoy seeds of Nauli F1 variety was used. Ripe manure of cow was used at 0, 10, 20, and 30 t/ha. Bio-extreme dosage were of 0, 50, and 100 l/ha. Observed data were plant height, number of leaf, weight of the whole plant on the harvest plot, and selling weight of the plants. The result revealed that the estimated variance component of the blocks, manure of cow, Bio-ekstrim, and error contributed 1.97, 72.50, 0.28, 9.74, and 15.50% to total variation (100%). The combination of manure of cow (30 t/ha) and Bio-ekstrim (50 l/ha) was the best to produce the highest selling weight of the plants i.e 15.14 t/ha.

Abstract
Drought is a common obstacle in crop cultivation. One third of the world’s food land is experiencing drought, which is increasing from year to year. Mitigation measures are needed to maintain national food security. The use of compost and biochar on Ultisol soils can increase crop yields and productivity under drought stress. Research on Jantho Ultisol soil with low fertility using a soil amadement of 10 t. ha−1, compost can increase soil pH from 4.57 to 5.97 at 50% field capacity soil moisture, an increase in sorghum yield from 1.54 t.ha−1 to 3.37 t.ha−1. Application of biochar 10 t.ha−1 increased pH from 4.57 to 5.03 at 50% field capacity soil moisture, an increase in yield from 1.5 4 t.ha−1 to 2.65 t.ha−1 with 600 kg ha−1 NP K fertilization at 50% soil field capacity moisture. The application of compost and biochar was effective in increasing soil pH and sorghum yield on Ultisol soil. This has mitigated the impact of drought and is an opportunity to increase productivity, diversify of food to increase food security towards food sustainability.

Abstract
Palm oil is one of the leading plantation sectors in Indonesia. Palm oil product which consists of crude palm oil and palm kernel oil has a high economic value. Indonesia has an area of 34.18% of the world’s oil palm plantations. Aceh province is recorded to have an area of oil palm reaching 488 thousand hectares in 2020, with an area of oil palm plantations owned by Indonesia, especially Aceh, making a palm oil counting process to calculate the amount of fertilizer used in each tree circumference and calculate the amount of oil palm production into work which takes time and price is quite expensive. The purpose of this study is to counting the number of oil palms by using the template matching method on aerial photo images. The template matching method consists of 3 stages of analysis, that is: Select sample, Generate templates, and Test template. The result of this study obtained 9.558 oil palm trees, but it is still necessary to edit the attribute because there are some trees that are not detected and there are two points on the tree one plant.

Abstract
This research is directed to overcome the problem of upland rice seeds that are no longer pure, because they have been mixed with other types of rice seeds, which can result in a decrease in the quality or nature of superior upland rice which is already favorable by the community. Seed purification is needed to restore the purity of the seeds of superior local upland rice lines. Another target of this research is to produce basic seeds of pure local upland rice lines (without mixture), which are needed for further breeding programs, or for the purpose of releasing varieties, as well as for production purposes for consumption. This study aims to select and detect the same/uniform morphological characteristics of local upland rice in each seed lot and to find out which seed lots show high uniformity. The experiment used a Randomized Block Design (RBD) consisting of 20 seed lots as treatment and each seed lot was made into a so-called “grid” (replication) of 3 grids. This research was conducted at the Field Laboratory, Experimental Garden II, Faculty of Agriculture, Halu Oleo University. Observational data were analyzed with variance and qualitative characters were converted to binary data and analyzed by the NTSYS program. If there is a significant effect, then proceed with the Scott Knott group test (α = 0.05). The results showed a very significant effect on the variables of flowering age, productive tillers and flag leaf angle, and no significant effect on the variables of plant height, number of leaves, number of tillers, harvest age, panicle length, flag leaf area, total grain per panicle and percentage of grain. per panicle.

Abstract
Aphids (Aphis gossypii) are the main problem in patchouli plants (Pogostemon cablin). The presence of aphids on patchouli plants is very worried by farmers, because it can damage patchouli plants by feeding the leaf which can reduces plant growth. Therefore, it is neccesary to learn more about biological of A. gossypii on patchouli plants. A gossypii was taken from Nino Park, Syiah Kuala University and Lamteuba, Aceh Besar. The patchouli used was the result of maintaining cuttings for two months to be used as an object of observation. Infestation A gossypii was carried out in 10 observation polybags. Observations were made by looking at the development time of A. gossypii including the nymph phase (instar I-IV) and imago A. gossypii. The experiment showed that the life cycle of A. gossypii lasted for 23.8 ± 4.76 days. A. gossypii had four instar stages, duration time needed each instar is 2 days, it means the duration of nymphal stage A. gossypii on patchouli is 8.8 days. The lifecyle of imago A. gossypii is 15 days. There were two types of imago, winged and wingless aphids imago, caused the population density of aphids on a plant.

Abstract
A study on the potential of rosella flower petal (Hibiscus Sabdariffa L) juice in optimizing the profile of fermented goat’s milk has been conducted at the Science and Technology of Milk Processing Laboratory, Faculty of Agriculture, University of Syiah Kuala Banda Aceh Darussalam. The purpose of this study was to examine the profile of fermented goat’s milk with the addition of rosella flower petal juice. In this case, the lactic acid bacteria used was Lactobacillus plantarum. Furthermore, this study applied a completely randomized research design consisting of 5 (five) treatments, namely P0 = control, P1 = 2.5% rosella petal juice, P2 = 5% rosella petal juice, P3 = 7.5% rosella petal juice, and P4 = 10% rosella petal juice, and each treatment was repeated 4 times. Starter L. plantarum was used with a 5% level. Parameters measured were pH value, lactic acid content, total plate count (TPC), vitamin C content, and the level of syneresis of fermented milk. The results showed that the addition of rosella petal juice with different percentages had a very significant effect (P<0.01) on increasing vitamin C levels, significantly increasing lactic acid levels (P<0.05), and reducing syneresis levels, but had no effect on pH and TPC. The highest levels of Vit C and lactic acid and the lowest levels of syneresis were obtained by adding 10% rosella petal juice. It can be concluded that the results obtained still meet SNI standards and the addition of 10% rosella flower petal juice produced fermented goat’s milk with the best profile.

Abstract
The aim of this study was to determine the effect and level of wet fermented feed containing a combination of maggot flour (Hermetia illucen) and active digestive enzymes on the growth and protein retention of early-phase on hybrid chickens. The experimental design used was Completely Randomized Design consisting of 4 ration treatments and 4 replications. The treatment rations used were: P0 (100% commercial/control feed), P1 (wet fermented feed + 9% maggot flour and 0.5 %), P2 (wet fermented feed + 12% maggot flour and 1% bioresic), P3 (Wet fermented feed). The parameters: ration consumption, weight gain, final body weight, ration conversion and protein retention. The results showed that fermented diet contained maggot flour with different feeding levels and active digestive enzymes had no significant effect (P>0.05) on final body weight, weight gain feed consumption, feed conversion and protein retention of hybrid chickens on 12 weeks of age. However, it had a significant effect (P<0.05) on the weight gain of hybrid chickens on 6 weeks of week. It was concluded that the use of 9-12% maggot flour and 1% active digestive enzymes did not have a negative effect on the growth and protein retention of 12-week-old hybrid chickens and could compensate and replace the role of commercial diet in stimulating the growth in early phase of hybrid chickens.

Abstract
Gayo horse is one of the livestock commodities developed in Southeast Aceh. This is supported by the Decree of the Minister of Agriculture of the Republic o f Indonesia. number 1054/Kpts/SR.120/10/2014 which stipulates the gayo horse as an animal genetic resource for the local Indonesian horse family with distribution in the d i s t r i c t s of Central Aceh, Bener Meriah, Gayo Lues and Southeast Aceh. This study aims to determine the role of the existence of the gayo horse for the Alas tribe that has cultural value and is prospective and to determine the strategy for developing the gayo horse in the area of Southeast A c e h Regency. Collecting data using survey method. The research location was determined using purposive sampling technique. Data was collected through in-depth interviews with 30 respondents of Gayo horse breeders based on the research instrument. Data analysis used descriptive statistics. The results showed that the characteristics of breeders were male with the highest average in the age group of 45-65 years, the lack of breeders in the productive age range was influenced by the influence of outside culture which was very fast in eroding the noble values of the area. The average number of breeders in the research location has experience of raising horses for 10–20 years (17%) and the number of horse ownership under 5 has the highest percentage (36%) 40% have high school education, and 88% are breeder’s horses have never attended technical training in the field of animal husbandry, 92% o f breeders keep gayo horses as a means of cultural ceremonies. The prospect of gayo horses in Southeast Aceh Regency is very high because it is very closely related to community activities that are still closely related to cultural activities that also use horses as mounts during traditional events such as pemamanan, turun mandi and antat takhuh with an average of ceremonial activities reaching 15-40 times per month for 11 months per year. Through the approach of cultural values, it is one of the efforts to maintain and maintain the existence of the gayo horse species in Southeast Aceh Regency.

Abstract
Studies on identifying numerous algae species to study the digestibility of the rumen have yet to be widely reported, especially with the numerous algae from tropical oceans. This experimentation was created to assess the gas production of four tropical algae species from Kelapa beach, Tuban, East Java, in vitro. The study used a randomized block design with four treatments (four algae species: Laminaria sp., Padina australis, Eucheuma cottonii, and Gracilaria sp.) and four replicas. The variables kept included gas production (measurement at 2, 4, 6, 12, 24, 48, 72 h, from an easily degraded fraction (a), from a potentially degraded fraction (b), rate of gas production of b fraction, and total fraction degraded and fermented (a+b fraction). Data was applied operating Analysis of Variance (ANOVA) for the significantly different data, and DMRT was applied to compare the treatments’ means. Laminaria sp. resulted in the highest gas production at 2, 4, 6, 12, 24, 48, and 72 hours of incubation time, highest total gas production, easily degraded fraction, potentially degraded fraction, and total fraction degraded and fermented than others, in difference with Gracilaria sp. resulted in the lowest of the parameters. It is supposed that the brown algae (Laminaria sp. and Padina australis) had more prospects of being degraded in the rumen than red algae (Eucheuma cottonii and Gracilaria sp.)

Published: June 2023

Abstract
Red chili is an agricultural commodity with high economic value. National red chili production is still low and often does not meet the needs of the Indonesian people. One of the causes is anthracnose disorder. Red chili anthracnose caused by the fungus Colletotrichum capsici is characterized by symptoms of small black spots that can widen, dry out and shrink and the fruit can fall off. The aim of the study was to determine the effectiveness of extracts of several types of weeds with distilled water at different temperatures against anthracnose disease, growth, and yield of red chili plants. The study was a field experiment using a two-factor Completely Randomized Design (CRD). Factor 1 Types of weeds consist of: bandotan, kirinyuh, teki. Factor 2 Aquades Solvents with Different Temperatures consist of: room temperature, 50°C, 90°C. The variables observed were the intensity of anthracnose disease, plant height, number of healthy fruit, healthy fruit weight, number of sick fruit, phytotoxicity test and phytochemical screening test. The process of spraying botanical extracts is carried out once a week. The results showed that the type of weed extract treatment had a significant effect on the intensity of anthracnose disease and the number of sick fruits and had no significant effect on the number of healthy fruit, healthy fruit weight, and plant height. The treatment of distilled water with different temperatures did not significantly affect all observed variables. The interaction between the type of extract and the temperature of the solvent had a significant effect on the number of sick fruits. Bandotan extract treated with distilled water at room temperature produced the least number of sick fruits, namely 3.4 fruit/plant. The solvent temperature of 50°C produced more phytochemical compounds than the 3 types of weeds extracted. Red chili plants do not show any phytotoxic symptoms.
