One of the limiting conditions for shallot plants to grow optimally is dry land conditions. Indigenous AMF application is one way to overcome this condition. This study aimed to determine the effect of indigenous AMF application on the morpho-physiological characters of two shallot varieties which are sensitive and tolerant to drought stress conditions. The study was carried out for 6 months on a wirehouse and laboratory scale. The Experiment used a completely randomized design with two factors. The first factor was varieties of shallots, i.e. Brebes (Sensitive) and Kuning (Tolerant) varieties of shallots. The second factor was the application of indigenous AMF which consisted of 5 levels i.e. Glomus sp1, Glomus sp2, Glomus sp3, a mixed those three isolates and control treatment (without application of AMF). The morpho-physiological observation parameters included header dry weight, root weight, and leaf proline content. From the observations, it can be concluded that under stressed conditions, the leaf proline content of the sensitive variety accumulated higher in the header than the tolerant variety, because the tolerant variety was better able to produce higher root and header weights when adapting than the sensitive. AMF inoculation did not show significant differences with the treatment without AMF inoculation on leaf proline. However, there was a tendency that inoculation of a mix of AMF isolates (Glomus sp1+Glomus sp2+ Glomus sp3) decrease the proline content in the leaves, both in sensitive and tolerant varieties so that plants are more resistant to drought stress.

Nitrogen and Phosphorus fertilizers are required to enhance the plant growth and yield. The appropriate nitrogen and phosphorus doses on the growth and yield of dragon fruit (Hylocereus polyrhizus) are not well known. A study to evaluate the effect of nitrogen and phosphorus fertilizers on the growth and yield of dragon fruit (Hylocereus polyrhizus) was arranged in a completely randomized block design with two factors and three replications. The treatments consisted of four nitrogen doses (0, 50, 75 and 100 g-1pillar) and four phosphorus doses (0, 50, 75 and 100 g-1pillar). Growth and yield were significantly (p < 0.01) affected by increasing nitrogen and phosphorus doses and showed interaction on the number of shoots, number of flowers, and fruit sets. The number of shoots increased from around 102.98 to 162.10 % at nitrogen dose 100 g and phosphorus doses 50, 75 and 100 g compared with no treatment. Nitrogen dose at 100 g and phosphorus dose at 100 g produced 152.64 % more number of flowers compared to 0 g phosphorus. The fruit set increased by 58.32% at dose of 50 g nitrogen and 50 g phosphorus. Nitrogen applied at 100 g compared with 0 g nitrogen and phosphorus at different phosphorus doses increased in the number of fruits were 139.35 % and 13.56 - 58.15 %. Individual fruit weight among nitrogen doses and TSS among nitrogen and phosphorus doses showed no significant difference. Application of nitrogen fertilizer at 50 g-1pillar and phosphorus at 75 g-1pillar produced maximum yield, respectively, and thus, it should be recommended as optimum doses.

Proper processing of coconut shell charcoal can be highly economically and environmentally valuable. The two most common uses of coconut shell charcoal are activated carbon and briquettes, obtained through carbonization. However, traditional carbonization methods involving kilns can produce excessive smoke, polluting the environment and disrupting human activities. A carbonization kiln that produces less smoke is required to address this issue. In this study, a kiln made from a steel drum with a sealer belt was fabricated to trap burning smoke inside the kiln. The results showed that adding this belt effectively reduced the smoke produced, making it more eco-friendly. Regarding charcoal production efficiency, different weigh coconut shells were burnt to produce charcoal. The result showed that burning 25 kg of coconut shell was optimal, producing a 48% charcoal content.

The residue of thermal power plants is known as coal fly ash and has been considered solid waste pollution worldwide. The characteristic of coal fly ashes showed that it contains several components that could be utilized in several fields. One of the potential utilization is in the agricultural application. This study analyzed the characteristic of two different types of coal fly ashes and their effect on the soil. The x-ray fluorescence (XRF) analysis resulted that SiO2, Al2O3, Fe2O3, CaO dan MgO are the five major components in the soil, and both coal fly ash, CFA A and CFA B. This XRF analysis result concluded that coal fly ashes have great potential to be a substitute for silica fertilizer. Then, the effect of the coal fly ash addition also was studied by the moisture content and nutrient (N, P, and K) content characteristics in the soil and the soil-ash mixture. The findings indicated that the addition of 125 grams of coal fly ash A had a greater impact on the soil compared to fly ash B when 250 grams of soil was used.

Pectin has numerous applications in the food industry because of its gelling capability. Dragon fruit peel is an ideal source of pectin since it contains pectin of around ± 10.8% of the weight. In this research, the extraction of pectin from dragon fruit peels used ultrasonic waves. This study was an experimental research with three independent variables that was a type of acid (HCl and CH3COOH), acid concentration (0.1 N and 0.2 N), and extraction time (30, 60, and 90 minutes). The control sample was pectin extracted by conventional methods, dipped in 0.1 N acids at room temperature for 24 hours. The result showed that the ultrasound-assisted extraction was an effective method to extract pectin from peels of red dragon fruits, whereas the yield was even twice that compared with the control sample. The treatment of 90 minutes of sonication in 0.2 N HCl produced the highest yield (2.71%). The pectin has a yellowish to a white degree of color and a 2.22 g.s/cm viscosity. It has a 902.2 mg equivalent weight, 6.14% methoxyl content, 54.4% galacturonic acid content and 63.8% esterification degree. The value of esterification degree and methoxyl content indicated that pectin from this research is high ester-pectin and low-methoxyl pectin.

Kidney beans and soybeans have the potential to be developed because they contain good nutrient. Kidney beans and soybeans are sources of vegetable protein. One form of development of legume products is composite flour. The aim of this study was to analyze the physical and chemical characteristics of composite flour made of kidney beans and soybeans. The experiment was designed using Completely Randomized Design with nine treatments and each treatment was replicated three times. The factor investigated was formulation of composite flour made from kidney bean and soybean (90%:10%; 80%:20%; 70%:30%; 60%:40%; 50%:50%; 40%:60%; 30%:70%; 20%:80%; and 10%:90%). The swelling power, solubility, color, white degree, moisture content, ash, protein, fat, and carbohydrate content were analyzed. The results showed that the higher percentage of soybean flour caused a decrease on swelling power, white degree, and redness of composite flour, but it increased the value of solubility, lightness and yellowness of composite flour. Composite flour with higher percentage of kidney bean flour had higher carbohydrate level, while composite flour with higher percentage of soybean flour had higher protein and fat content. The moisture contents of composite flour made of kidney bean and soybean were in accordance with the standard for beans flour products.

Cinnamomum burmanii L, a cinnamon plant developed in Indonesia, requires high-quality seeds, yet plant propagation faces challenges due to limited access to quality seeds at the appropriate time. This study aimed to determine the viability of cinnamon seeds from the level of maturity of the seeds and size. The experimental design used in this study was a randomized completed block design with a factorial pattern, with the first-factor treatment being the maturity level of the seeds, namely: 1) K1 (purple) and 2) K2 (purplish-green). The second factor was the size of the seeds, namely: 1) U1 (large size) and 2) U2 (small size) at different storage times, namely at the beginning of storage, 4,7, and 10 days after storage. The observed variables included water and carbohydrate content, germination, and seed vegetative growth (seed height, number of leaves, leaf length, leaf width, roots, and root length). The results showed that the interaction of cinnamon seeds with large size and purple maturity level had the highest viability in all storage periods. Germination reaches 70%, carbohydrate content 15.28%, and moisture content 10.51% ten days after storage.

Soybean seed procurement was challenging due to the quality degradation during the seed storage period. Seed coating is necessary in order to overcome the leakage of seed metabolites. Seed coating has to be supported by a storage package that can protect the seed from temperature and humidity fluctuations in storage. This study aimed to determine the effect of seed coating using antioxidants and storage packaging to maintain the viability and vigor of soybean seeds. The experiment was carried out factorially with the basic pattern of Completely Randomized Design (CRD) and was repetitively replications by three times. The first factor was seed coating, which consisted of 4 levels such as M1=no coating, M2= 3% of Arabic gum + ascorbic acid, M3= 3% of Arabic gum + tocopherol, and M4= 3% of Arabic gum + mangosteen peel extract. The second factor was that the storage package consisted of 3 levels, which were N1= aluminum foil, N2= polyethylene plastic, and N3= plastic sack. The interaction between the seed coating material and storage package on seed moisture content with the best treatment was seed coating using ascorbic acid and aluminum foil package, seed coating treatment carried out the best effect without implementing the seed coating, and the storage package treatment that presented the best effect was aluminum foil package.

This research is located in Batang Mahat Lima Puluh Kota Regency, about 9.26 km2 from the narrowing location at Batu Kisok to the upstream, prone to flood. Due to several flooding events in Batang Mahat, various assumptions and hypotheses have emerged regarding the causes of Batang Mahat flooding. This research analyses the causes of flooding in Batang Mahat using Steady Flow simulation in HEC-RAS 6.2 software. The result implies that two factors caused the flood: (1) The channel capacity is insufficient to accommodate flood water discharge, where the simulation results shown at the Q50 discharge (2003.07 m3/s) flood inundated several areas in cross-sections upstream and tributary. (2) The impact of the narrowing location at the river channel in Batu Kisok, which is shown by the simulation of a decrease in water elevation at eight cross-sections at the upstream and two cross-sections at the tributary after the cross-sections in Batu Kisok are widened from ±30 m to ±45 m (50%), ±60 m (100%), and ±75 m (150%).
本研究位于Batang Mahat Lima Puluh Kota Regency，从Batu Kisok狭窄的位置到上游约9.26 km2，容易发生洪水。由于Batang Mahat的几次洪水事件，关于Batang Mahat洪水的原因出现了各种假设和假设。本研究利用HEC-RAS 6.2软件中的定流模拟分析了巴塘马哈特洪水的成因。结果表明:(1)河道容量不足以容纳洪水泄洪，其中模拟结果显示，Q50流量(2003.07 m3/s)洪水淹没了上游和支流断面的多个区域。(2)巴图基苏克河道位置变窄的影响，通过模拟巴图基苏克河道从±30 m加宽到±45 m(50%)、±60 m(100%)和±75 m(150%)后，上游8个断面和支流2个断面的水位下降来体现。

Due to several flooding events in Batang Mahat, various assumptions and hypotheses have emerged regarding the causes of Batang Mahat flooding. This research analyses the causes of flooding in Batang Mahat using Steady Flow simulation in HEC-RAS 6.2 software. The result implies that two factors caused the flood: (1) The channel capacity is insufficient to accommodate flood water discharge, where the simulation results shown at the Q50 discharge (2003.07 m3/s) flood inundated several areas in cross-sections upstream and tributary. (2) The impact of the narrowing location at the river channel in Batu Kisok, which is shown by the simulation of a decrease in water elevation at eight cross-sections at the upstream and two cross-sections at the tributary after the cross-sections in Batu Kisok are widened from ±30 m to ±45 m (50%), ±60 m (100%), and ±75 m (150%).","PeriodicalId":33922,"journal":{"name":"Journal of Applied Agricultural Science and Technology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89119732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Tree nuts and groundnuts nowadays are gaining popularity due to their health benefits. Nut kernels that can be eaten raw or roasted are becoming increasingly popular in healthy diet, including canarium nut. Therefore, it should be used into a variety of food compositions, including butter, to promote a healthy diet and lifestyle. The objective of the research was to determine the exact sugar concentration in the production of canarium nut butter. A completely randomized experimental design with four levels of sugar concentrations i.e. 0%, 20%, 40%, and 60% was applied in this research. Chemical and sensory properties were analysed. Results showed that the sugar concentration of 40% was the exact concentration for producing canarium nut butter. The canarium nut butter at 40% sugar concentration had a moisture content of 17.70%, an ash content of 2.68%, a protein content of 6.19%, a fat content of 32.69%, and a reducing sugar content of 25.31%. Canarium nut butter at 40% sugar was also more liked on taste, texture, and its overall likeness; it was only slightly liked on aroma. This butter was rated as sweet, having a nutty aroma, smooth, and very easy to spread.
