Abstract
This study aims to determine the nutritional values of elephant grass to save critical land and provide forage quality animal feed which decreases due to conversion. This study employed the experimental method using a randomized block design with five types of treatments and four replications (groups). Fungi Mycorrizal Arbuscula (FMA) cv. Glomus manihotis will be inoculated at a dose of 10 grams/clump. The treatments comprise of A = 100% N, P, and K without FMA; B = 100% N, P, and K + FMA; C = 75% N, P, and K + FMA; D = 50% N, P, and K + FMA; E = 25% N, P, and K + FMA. The analysis results show that the treatments on the characteristics of rumen fluid, gas production, and metabolism energy (ME) are not significantly different (P > 0.05). The pH ranges from 6.86 (E) to 6.89 (B); the N-NH3 ranges from 11.20 (A) to 13.60 mg/100 ml (C); the VFA ranges from 93.3 (A) to 130.30 mM (E); gas production ranges from 34.40 (A) to 40.42 (ml/200 mg DM) (E). To conclude, adding 25% N, P, and K Fertilizer + FMA of Glomus manihotis 10 grams is the best process for the characteristics of rumen fluids and gas production.

Mycorrhizal Fungi (AMF) CV. Glomus manihotis on yield, production, and revenue cost ratio (RCR) of Pennisetum purpureum of CV. Taiwan in ultisol soil for the first harvest in West Sumatra, Indonesia. The N, P, and K fertilizers for AMF CV. Glomus manihotis inoculation is used at recommended doses of 100%, 75%, 50%, and 25%. Whereas, AMF is inoculated with a dose of 10 grams/grass plant clump. This research employed Bisozyme DT 1000 type and Bisozyme MK 1000 type. This research was conducted using a randomized group design, four groups, and five variables. The groups were P0 (Manure + Fertilizer N, P, and K), P1 (Bisozyme), P2 (AMF CV. Glomus manihotis), P3 (Bisozyme + AMF CV. Glomus manihotis), and P4 (Bisozyme + AMF CV. Glomus manihotis + N, P, and K). The variables were yield, dry production, and RCR. The results of the statistical analysis have shown that the treatments are not significant (P < 0.05) for yield and dry production. Meanwhile, the RCR of grass is significantly different (P > 0.05). The yield, dry production, and RCR range from 57.50 (P1) to 66.53 (P4) ton/ha/year, from 12.18 (P1) to 14.93 (P4) ton/ha/harvesting, and from 1.54 (P2) to 6.71 (P0). These results conclude that Bisozyme mixed with FMA could be used as organic fertilizers to substitute N, P, and K fertilizers.

Abstract
Plant material conservation for traditional cuisine in a particular ethnicity is very important to preserve their culture for sustainable utilization. Sawahlunto City consists of a multi-ethnic community with various cultures, customs, and traditions. This fact results in a unique variety of food types and diverse materials. Preliminary ethnobotanical research was conducted on two research sites (Talago Gunung and Rantih Village) in Sawahlunto district. This study aimed to investigate the variety of Minangkabau traditional foods in the Sawahlunto district of Indonesia. The data were obtained from sixteen respondents in the research sites through semi-structured interviews. The collected data were analyzed qualitatively and quantitatively. Quantitative analyses included the Use Value (UV) and Cultural Food Significance Index (CFSI) of each plant. The plant materials were identified and deposited at the Herbarium of Universitas Andalas. This study has revealed three main types of traditional foods: ‘ayam bungo jua’, ‘udang kasambi,’ and ‘gulai ayam talanjao.’ These three types of traditional cuisine have different plant diversities and use 18 plants species from 13 families. Shallots (Allium ascalonicum) is a pivotal plant to make the three traditional foods because it provides the highest UV value of 2.06. Another important case shows that culturally important plants with the three highest CFSI values are detected in red chili (Capsicum annuum), shallot (Allium ascalonicum), and garlic (Allium sativum). The detailed plant diversity and their conservation in this research are discussed in this article.

Abstract
Many researchers and industry players are investigating possible uses of natural fibres in order to raise environmental consciousness, preserve nature, and benefit social economy. In the composite business sector, there are several advantageous natural fibre sources open up for a variety of applications. It is worth noting that the performance of natural fibre-reinforced composites may be customized by natural fibre treatment and hybridization. An equilibrium between environmental consequences and desired performance as well as cost-effectiveness may be accomplished by developing composites depending on the product needs. However, some limitations, including their hydrophilic nature and their tendency to absorb moisture during processing, severely restricts natural fibres’ potential for use as reinforcements in polymer composites. Thus, the key discoveries provided in the extant literature are reviewed in this brief overview, with an emphasis on the qualities of natural fibres and their recent progress in several engineering areas.

Abstract
Soil investigation is an effort to obtain underground information for planning civil building foundations. The existence of a soil investigation can determine the bearing capacity of the foundation. One type of foundation that is planned is a caisson foundation. Soil investigation includes, among others, soil drilling, soil sampling, field testing and laboratory testing. A Referring to the technical data, the caisson foundation plan scheme used has a diameter of 60-1000cm, the selection of the most suitable diameter is adjusted to the load plan of the superstructure while the foundation depth is recommended to pass through a bedrock layer of 20-30cm. Technically, the soil layer is sufficient to withstand vertical loads, this is indicated by the value of Qc>150kg/cm2 and NSPT>60, but the location of the building is on sloping land with the distribution of bedrock layers that have a slope following the profile of the soil surface, so the potential for uplift is ) can occur due to lateral forces, this is also supported by the uneven embankment material from the original soil surface profile so that the load acting is uneven on the embankment layer.

Abstract
Bubil is one of the materials needed for porang plant propagation. Bubil is a vegetative propagation material that is found on each meeting of the stem and takes three to four months to germinate. The length of time for bubil germination is often a problem in the cultivation of porang plants. One of the efforts made to speed up germination time is to use growth regulator treatments. The purpose of this study is to determine the best duration for the soaking of shallot extract on the germination of the bubil porang plant. This study used a completely randomized design (CRD) consisting of four treatments and three replications. The treatments used were B0 = 1 hour, B1 = 2 hours, B2 = 3 hours, and B3 = 4 hours. The research data were analyzed using the Anova table, if the F count is greater than the F table of 5%, then a further test is carried out with the Tukey test at a 5% significance level. The observed variables were the time of the emergence of plumules, the height of the seedlings, the number of leaf blades, and the width of the leaf blades. The results of the analysis of the Anova table showed that the duration of soaking the onion extract on the germination of the Bubil porang plants showed significantly different results with respect to the time of the emergence of plumules and plant height, but not significantly different to the number of leaves and leaf width. Out of the four treatments used, a soaking time of 4 hours gave the best results on the time of emergence of plumules (77 days after sowing) and the height of the seedlings (23.50 cm).

Published: October 2022

Abstract
We have evaluated the process of watersplitting into hydrogen gas. Electrolysis-photocatalysis reactor is used to harvest hydrogen gas through water splitting, a combination of electrolysis and photocatalysis reactions. The concentration of hydrogen gas (H2) is detected by the MQ-8 sensor and the number of bubbles is calculated. Evaluation of watersplitting is done by varying the DC voltage source (3V, 6V, 9V, 12V). We found the highest concentration of H2 gas was produced at 12 volts 616300 ppm for 600 seconds, The largest increase from the photocatalyst-electrolysis reaction combination was found to be 182017 ppm. Here we observe a linear increase in hydrogen with increasing voltage which results in a faster electrolysis process. But what is most interesting is the increase in H2 during the simultaneous electrolysis-photocatalysis process. the combined reaction has increased the amount of hydrogen greater than the sum of the photocatalytic and electrolysis reactions taking place separately. It is most likely that a mutually reinforcing reaction occurs so that the overall activation energy of the system becomes smaller in the process of dissociating water into hydrogen.

With a flood control capacity of 41 million m3 with an initial capacity of 347.82 million cubic to 239.76 million cubic due to increased sediment in the reservoir so that if there is high rainfall it has the potential to cause flooding. The research entitled “Inflow Analysis to Bili-Bili Reservoir”, has a problem formulation of how the relationship between rainfall and inflow (discharge) entering the reservoir and how the comparison between inflow based on rainfall data and AWLR (Automatic Water Level Recorder). The purpose of this study was to analyze the relationship between rainfall and inflow discharge into the reservoir and to compare the inflow discharge based on the results of rainfall analysis with the inflow based on AWLR. This study uses secondary data from the Pompengan Jeneberang River Basin Center (BBWS). The regional average rainfall analysis used the Thiessen method, while the Synthetic Unit Hydrograph (HSS) Gama I method was used for flood discharge analysis. For flood discharge analysis, the maximum annual rainfall was selected according to the maximum inflow recorded at the Bilibili Dam AWLR. From the calculation of the HSS Gama 1 parameter, the rise time is 2.72 hours and the peak ordinate is 10.290 m3/second. When compared with the inflow (discharge) data on the Bili-Bili AWLR, the results of the calculation of the discharge with HSS Gama I are smaller in value with a difference of 20.50% to 31.46%.

Abstract
Microclimate control is increasingly widespread in limited agricultural environments. This is especially important for the cultivation of plants that tolerate significantly different thermal and hygrometric conditions. Nevertheless, there is much to be done in automation and control technology in this area to achieve the best results in both quantitative and qualitative terms of the product. This applies especially to horticultural crops that are sensitive to the cultivation environment and microclimate. This work aims to characterize the microclimate parameters in a confined agricultural environment with perforated ducts for air conditioning supply. For this work, a microclimate control unit was used instead of a lettuce crop. It was placed into a confined agricultural environment at different locations in the space to obtain the main microclimate parameters. After setting the input of the microclimate environment, the instrument measured a series of physical quantities (temperature, radiant temperature, humidity, and air velocity). Tests were carried out by taking the optimum day temperature constant for growing lettuce and by varying the supply airflow rate by setting the fan speed at 30%, 50%, and 80%. The results of these tests are essential for performing real-time control of the microclimate environment and for managing parameters for optimization of the entire system. In addition, the air velocity test showed adequate velocity reduction and good air mixing. The values obtained are generally acceptable for indoor cultivation and the conditions created are suitable for growing plants in such an environment. Light is an essential need for plants so that plants can carry out the photosynthesis process properly. In indoor DWC hydroponics system, the source of UV light is LED lights for plants. Some of the advantages of using LED light include a small light spectrum, less heat production, low power consumption, and wavelengths of 660 m and 450 m that are needed by plants. This research project aims to create a DWC hydroponic system for growing red lettuce in an indoor hydroponics and see the effect of LED grow light on the growth of red lettuce. DWC hydroponics uses AB-Mix nutrients that are channeled through inch PVC pipes using pump power. The hydroponic rack used has a height of 1.7 m and a width of 40 cm and has 3 shelves, where each shelf has 9 nutrient containers. The red lettuce plants in the DWC system were provided with different light treatments by installing shading nets with different percentages of light penetration, namely, 75%, 50%, and 0%. From the results of these treatments, the average yield of red lettuce was 300 grams on the top shelf, 400 grams on the middle shelf, and 600 grams on the bottom shelf.
