Abstract
The involved object of systematic innovation and management is neither a single goal nor a single meth-od. Firstly, the research object is a systematic and organic whole composed of multiple node elements with a certain degree of correlation. Secondly, the research method is multi-dimensional, comprehensive, all round and highly efficient. Innovation should break through the existing thinking framework, change the existing structure, add new components, give new energy and produce new functions. The 5W1H is a questioning approach and a problem-solving method that answers all the basic elements within a problem which are what, who, when, where, why, and how. It aims to view ideas from various perspectives and gain an in-depth understanding of a specific situation. On the basis of 5W1H analysis method, this paper puts forward the 6WHI systematic innovation management method, which increases the query words weather and if of the innovation expansion solution, increases the number of questions from 6 to 8, and expands innovative forward-looking and innovative solutions diversity, with smoother pronunciation, more exciting storm. Furthermore, a systematic innovation method based on 6WHI and total factor analysis is established, and a more general and normative model WIME method is presented. This method can be utilized as a continuous process-improvement technique in an organization. Taking the 17 letters of “if question patents” as the prefix, they are just 17 common key elements in system management and innovation. For each element mentioned above, 8 questions and answers of 6WHI are given to realize systematic management and innovation. The above two types of work are arranged according to the matrix format, and then the weighted evaluation method is introduced to evaluate the above management and innovation work, so as to give a general and standardized systematic management and innovation (WIME) method.

Abstract
In the Arctic, winter soil temperatures exert strong control over mean annual soil temperature and winter CO2 emissions. In tundra ecosystems there is evidence that plant canopy influences on snow accumulation alter winter soil temperatures. By comparison, there has been relatively little research examining the impacts of heterogeneity in boreal forest cover on soil temperatures. Using seven years of data from six sites in northeastern Siberia that vary in stem density we show that snow-depth and forest canopy cover exert equally strong control on cumulative soil freezing degrees days (FDDsoil). Together snow depth and canopy cover explain approximately 75% of the variance in linear models of FDDsoil and freezing n-factors (n
f; calculated as the quotient of FDDsoil and FDDair), across sites and years. Including variables related to air temperature, or antecedent soil temperatures does not substantially improve models. The observed increase in FDDsoil with canopy cover suggests that canopy interception of snow or thermal conduction through trees may be important for winter soil temperature dynamics in forested ecosystems underlain by continuous permafrost. Our results imply that changes in Siberian larch forest cover that arise from climate warming or fire regime changes may have important impacts on winter soil temperature dynamics.

Abstract
Sugarcane is considered one of the most promising crops. The growth of the crop is affected by photosynthesis and toter and nutrient absorption by plants. Biostimulant is a non-nutrient biomaterial that is proven to improve crop growth. Based on this idea, Biostimulant technology can be used as an alternative to enhance sugarcane growth. This research aimed to assess the Biostimulant consortium (Sucrosin, humic acid, and AM fungal) to improve the growth of the sugarcane var. Cenning in a dry land. The study tested two treatments, i.e., control (standard procedures) and Biostimulant Consortium application. Sucrosin was applied on 1, 3, 4, and 5 months after planting (MAP) by using a foliar spray. Application of mycorrhizal fungi was spread around the roots area of sugarcane crops. In contrast, the application of humic acid was sprayed on the ground as a coating agent for inorganic fertilizers. Coating fertilizer is carried out by mixing a humic acid solution with as much as 1% of the fertilizer. The research showed the treatment of the Biostimulant Consortium yielded significant results in the sugarcane growth compared to the control on 8 MAP. Biostimulant Consortium can improve crop height and stem diameter significantly up to 30-40% compared to control. It indicates that the Biostimulant consortium’s treatment can improve sugarcane’s vegetative growth in s dry land.

Abstract
Corn is the second-largest agricultural product after rice in Indonesia. The main problem faced in corn production is pests. This study aims to identify and learn the percentage of damage and lost production by the new invasive pest attack on maize in West Sumatera, Indonesia. The location took place in Padang Pariaman and Solok Districts. A survey was used in this research. The results exposed a severe attack of a new invasive pest, S. frugiperda. This pest was found in Padang Pariaman and Solok Districts. The percentage of damage by S. frugiperda in Padang Pariaman (0.71 larvae population per stem) was higher than in Solok District (0.52 larvae population per stem). Then, the population fluctuation of S. frugiperda in Padang Pariaman District was higher than in Solok district. The correlation between the population of S. frugiperda and the production of maize was carried out by regression analysis. The regression model is logarithmic, with a formula y= 380.87 ln(x) + 28 and a value R2= 1 for Batang Anai Subdistrict, and y = 213.52 ln(x) + 35 and a value R2= 1 for Kampung Dalam Subdistrict, Padang Pariaman. Then a formula y= 474.65ln(x) + 11 with a value R2= 1 for Tanah Garam Subdistrict, Solok, and y= 367.89ln(x) + 12 with a value R2= 1 for Tikalak Subdistrict, Solok. S. frugiperda is a new invasive pest, and the vegetative phase is susceptible to S. frugiperda on maize. This pest can cause lost production. If this pest is controlled too late, it can reduce the production of maize. Therefore, farmers must know the right time to control this pest.

Abstract
Ecological engineering has become a promising strategy for restoring paddy field biodiversity and enhancing yield. This study aims to evaluate the effectiveness of refuge plants and cropping systems on the population of useful arthropods and rice production. The study was conducted on a paddy field in Central Sulawesi, Indonesia, using a Split Plot Design. The main plots were refuge plants with four treatments, namely rice without refuge crops, rice crops with wild Cosmos (C. caudatus), marigold (Tagetes erecta), and both flower plants as the refuges, whereas two cropping systems, i.e., the jajar legowo system (JLS) of 2:1 and the symmetries system (SS) was set up as a sub-plot. Direct observation and collection of the arthropods were carried out using yellow-pan traps and a sweep net. The parasitoid eggs were reared at the laboratory. In addition, rice growth and yields were measured. The refuge plants and cropping system had no significant effects on the overall arthropods population but changed their diversity and community structure and increased the proportion of useful arthropods as well. Meanwhile, rice production in the JLS (5.16 tons GKG ha−1) was significantly higher than those of the SS (4.10 tons GKG ha−1), and this was in line with the differences in the panicles number in both cropping systems. The study highlighted the importance of the implementation of ecological engineering at the paddy fields by using the flower plants as the refuge and food sources for the beneficial organisms combined by JLS for enhancing the rice yields.
On the home-visiting dragons: a year-round observation of dragonflies (Insecta: Odonata) entering an urban residence

Abstract
Wildlife intrusion into human settlement and residency has long been viewed as a disturbance rather than regarded from other perspectives, such as wildlife welfare or conservation. Insects were part of that wildlife that were considered as pests or nuisances whenever their existence intersected with human livelihood. In this study, we documented a year-round (August 2019 to August 2020) observation of dragonflies intruding into a residence in the densely populated urban area in Padang City, West Sumatra, Indonesia. The study used the descriptive method, where the data was recorded from any occasion an individual or more dragonflies entered the house. The observation recorded the date and time of entry, species identification, and sex which was later analyzed. During the observation, we recorded 41 individuals entering the residence. They were classified into two damselfly species (Zygoptera) and ten valid dragonfly species (Anisoptera). Orthetrum sabina, Tholymis tillarga and Gynacantha dorhni became the most recorded species with 8, 7, and 7 total individuals, respectively. With 12 individuals recorded in a month, February 2020 was the most dragonfly-intruded period, much higher than the intrusion rate of 2.8 individuals per month. Dragonflies were observed entering the residence at midday (10 individuals), afternoon (12 individuals), evening (11 individuals) or night (8 individuals); this might suggest that night lighting might be what caused them to get into the residence. Both sexes were equal (18 females, 20 males, and three unsexed). The availability of tiny prey insects within the settlement area is another causative factor in this phenomenon. This intrusion should be alarming that the urbanization processes need to be reconsidered to be more ecological-friendly.

Abstract
The avocado plant is cross-pollinated; thus, each plant has a different genetic fashion. This research was carried out in 2020 in Luhak Nan Duo District, West Pasaman Regency. The research aimed to obtain information about the morphological characteristics and describe the diversity of avocado plants in Nagari Giri Maju, the center of avocado production in Luhak Nan Duo District, West Pasaman Regency. The research used a survey method with purposive sampling as a sample collecting design. Morphological characterization was carried out on avocado fruit. Exploration and characterization conducted successfully identified 238 accessions of avocado that showed variability in fruit shape, ripe fruit skin color, ripe fruit flesh color, fruit flesh texture, and fibrous within fruit flesh. Wide variability was detected only for fruit weight. Ten potential avocado accessions were obtained from the characterization with the following characteristics, i.e., oval fruit shape, grade A fruit weight, green color of ripe fruit peel, and buttery and non-fibrous fruit flesh texture. Hence, the accessions can be recommended for new potential avocado varieties. Based on qualitative traits, cluster analysis resulted in seven groups with a 38% degree of similarity.

Published: April 2024

Abstract
Macrochelidae is known as one of the acarine biocontrol agents which target agricultural pests. In this article, we conducted a literature review of the species of Macrochelidae (Acari: Mesostigmata) in Sumatra, Indonesia. The association between Macrochelid mite and insects and their potential use are also discussed. Most of the Macrochelid mites were collected from the surface body of dung beetles Scarabaeidae, captured by baited pitfall trap (human dung trap). Twenty-two species of Macrochelidae belonging to 5 genera are found in Sumatra. None of them is endemic, and there have been no reports of the use of Macrochelid for the agricultural system on this island so far. Therefore, intensive research on Macrochelidae on Sumatra Island is needed.

Abstract
Sesame has high nutritional value, sesame seeds contain oil, protein, sugar, water, ash, and two kinds of oleic acid and linoleic acid; sesame is commonly used in the diet or as a vegetable oil. Sesame is grown in many tropical countries, and the optimum temperature for sesame growth is 25-30 °C. Due to climate change, the temperature is increasing, in the Mekong Delta of Vietnam, the temperature in summer can reach nearly 35 °C. The research question is whether high air temperature affects sesame growth and yield. To answer the above question, the study was conducted in greenhouse conditions in An Giang province with different temperature conditions, including 3 extreme chambers from 32.7, 32.9, and 34°C; automatic fan and a misting system for to control temperature. Black sesame plants were grown in 42 pot (34 x 28 x 28cm), each chamber with 4 plants per pot. All pots were filled with the same amount of alluvial soil (Fluvi Mollic Gleysols). Results showed that accumulated growing degree days in chambers 1, 2, and 3 were 2115, 2019, and 1994 GDDs, respectively. At 2115 GDDs gave the highest value of fresh biomass (1417g/pot), dry biomass (276 g/pot), dry weight capsule (109 g/pot), and dry seeds (51 g/pot). Regarding harvest index, chamber 3 with 1994 GDDs gave the highest harvest index of 0.22; the other chambers were in the range of harvest index of 0.18-0.20. In conclusion, under greenhouse conditions with 2115 GDDs is ideal for the growth and yield performance of black sesame.

Published: April 2024

Abstract
Located in the Southwest of the Mekong Delta in Vietnam, An Giang province is an important center of agricultural production, especially rice cultivation. Climate change impacts are one of several man-made factors affecting water resource availability for agriculture in the province. It is recognized that new solutions are crucial to adapt to the present and future conditions of a scarcer water supply. This paper explores climate factors affecting water resource availability in agriculture and some recent adaptations being adopted by farmers in one district of An Giang province. Hydro-meteorological data was collected together with in-depth interviews as a tool to point to proximate changes in water status and availability and to evaluate local inhabitants’ awareness of climate risks and adaptive strategies. The results noted that climate factors (temperature, humidity, annual rainfall) have altered over time, causing decreased availability of water supplies for agriculture. Recognizing this situation, both structural adaptation and non-structural solutions may occur simultaneously to maintain agricultural production efficiency. The types of crops, tolerant varieties, and irrigation projects suitable for various geographical areas were considered for more adaptive agriculture production locally. To address some of the problems that farmers face, water-saving technologies are an essential part of a range of potential solutions to maintain agricultural production and protect the environment in the future.

Abstract
At the present time, climate change causing increasing temperature, dryness and CO2 has exposed negative impacts on crops. In this study, four independent chambers were built to establish the expectation of different temperatures between the chambers. The experiment was carried out from January to March 2021 at An Giang University experimental area. Corn variety “Gold 58” was grown in 42 pots (34x28x28cm) in a chamber, 2 plants/pot. Temperature and CO2 were hourly recorded. Plant height, leaf number, stover biomass were measured every 10 days period. The results showed that days to maturity in 4 chambers ranged from 62 to 67 days and accumulated temperature from transplanting or sowing to maturity (Tsum) varied from 1976 to 2077 0C d. The average of CO2 concentration of 10 days period in the chambers varied from 527.5 to 558.3 ppm at daytime and 626.1 to 744.4 ppm at night-time (highest in chamber 1). Plant height at harvest in chamber 1 was 306.7 ± 11.5 cm, while it was decreased by 6.1%; 11.7% in chambers 3 and 4. Total biomass above the ground in chamber 2, 3, 4 also significantly declined by 25.2%; 31.6% and 36.4% at harvest, respectively. Fruit yield also reduced by 14.3%, 34.9% and 34.1% respectively compared to chamber 1. Observed versus simulated comparison by our crop-model (based on R language programing) resulted in RRMSE value less than 8.2%. NSE index (Nash Sutcliffe Efficiency) of the models greater than 0.75 show that the models have high reliability.

Published: April 2024

Abstract
Volcanic ash and pumice are products of volcanic eruptions characterized by a high amount of amorphous silica and alumina. They can potentially serve as a source of raw materials for the production of geopolymers. Geopolymers are more environmentally friendly compared to conventional cement. However, there is a requirement for aluminosilicate for creating geopolymers. This study aims to identify the mineralogical composition and chemical properties of the volcanic ashes and pumices that are potentially used as geopolymers precursor materials. Tephra and pumice samples were collected from several volcanoes in Indonesia. The samples include two tephras from recently erupted volcanoes in Java and one pumice material from West Sumatra. Tephras were collected one week after the eruptions of Mt. Tangkuban Perahu (26th July 2019). Another source of tephra was collected from Mt. Kelud, which erupted on 13th February 2014. Pumice samples of Mt. Maninjau were collected at Sungai Limau district, 30 km from the Maninjau caldera, a product of the Holocene (52K) volcanic eruption of Mt. Maninjau. Mineralogy of the tephra and pumice samples was identified with XRF and XRD. Chemical properties characterized include pH, exchangeable cations, cation exchange capacity (CEC), potential-P, and available-P. Results showed that crystalline feldspar minerals and amorphous volcanic glass dominated volcanic ash and pumice. The SiO2 content is higher in pumice, followed by tephras from Mt. Tangkuban Perahu and Mt. Kelud (74.97%-60.28%). But the Al2O3 content is higher in Mt. Kelud compared to pumice and Mt. Tangkuban Perahu (23.57%-4.03%). The pH is very acidic to slightly acidic (2.35–6.1). Mg is higher than Ca, Na, and K. The potential-P and available-P were considered very low. Among the samples, Mt. Kelud volcanic ash has the highest available P compared to Tangkuban Perahu volcanic ash and pumice. The SiO2/Al2O3 ratio are 4.35, 8.00, and 26.38 for samples of Mt. Kelud, Mt. Maninjau pumice, and Mt. Tangkuban Perahu, respectively. The optimum ratio of geopolymer is between 2.5–5; thus, volcanic ash Mt. Kelud is the most suitable option. Nevertheless, the exchangeable basic cations of volcanic ash and pumice indicated that they are more suitable for plant nutrition.
