Published: December 2021

Abstract
Soil is the most important and basic element of earth. In India which have more type of soil which have low or high bearing capacity like black cotton soil which have high montmorillonite and kalinite. These are those type of soil which have high shrinkage and swelling property. This type of soil cannot withstand heavy load. So, to overcome such problem treatment of soil is needed to be done using plastic materials or volcanic ash, cement kiln dust(CKD) particles for stabilizing this soil. Soil stabilization is the process which improve the physical effects of soil shearing and bearing capacity which is use of adding the admixture like cement, fly ash, lime volcanic ash CKD. Engineers are develop new technique for soil stabilization. It is really big deal to use these type of waste to stabilization of soil. India is developing country build new building and break the old building. All this process many type of waste are generate and in Indian survey nearly 7.46 million tonnes of hazardous waste is generated in India annually So the engineers are think the all waste are used in soil stabilization This paper write for two reason, one is recycle the waste materials and other one is increase the soil stabilize. Some type of industrial waste are including the gravel and dirt concrete and masonry, oils, metals, industrial waste like gasses or solids and also count vegetables matters from restaurants. In other words the industrials waste is two type one is non-hazardous and 2nd is hazardous

Published: December 2021

Abstract
Behavior of multistory structures during solid seismic tremor relies on the underlying configurations.Irregularities are not avoidable in development of structures in light of the fact that the space accessible for building the structures are restricted consequently the structure with irregularity is built up more, because of these abnormalities in the structure damages are more during earthquake.The effect of lateral load as wind/Earthquakes influences the performance of these constructions significantly. For the stability against seismic forces of multi-celebrated structure, there is need to investigation of seismic examination to plan earthquake opposition structures. It was tracked down that principle reason for failure of RC building is due to irregular circulations of load, plan of the structures, strength, stiffness. In this paper the correlation of seismic behavior of G+15 story structures having plan irregularities was finished utilizing ETAB programming. For this reason different multi-storey structure plans are viewed as that are regular plan without shear wall, regular plan with shear wall, L shape without shear wall, L shape with shear wall, irregular plan of C shape without shear wall, irregular plan of C shape with shear wall structures. For the correlation, boundaries taken are displacement, story float and storey shear. Every one of the six structures was dissected for zone V. The fundamental objective is to contemplate the behavior of both symmetric and Asymmetric structures during seismic tremor having abnormalities in plan but the plan area is same. The another aim of the study is to examine the taken boundaries like storey shear, storey displacements, Maximum storey float of all structures that are build in this paper during seismic tremor and also to study the impact of shear wall on the behavior of different structures.

Abstract
The use of inorganic fertilizers with high doses is not recommended in the sustainable maize production program. The present study aimed to evaluate soil chemical properties and growth of maize plants treated with several types of manure to reduce the use of chemical fertilizers in sandy soil. An experiment was conducted in dryland with pumped deep-well water in Gumantar Village, North Lombok Regency, from May to July 2021. There were three types of manure tested: cow, poultry, and goat manures (20 ton/ha) treated with and without BeKa decomposer. All the manure treatments received 75% of chemical fertilizers applied in the control treatment (500 kg of urea and 380 kg/ha of NPK Phonska). The treatments were arranged in a randomized block design with three replicates. The results showed that the poultry manure treatments, with and without decomposer, increased soil pH significantly. This increase improved soil chemical properties, such as available P and K. Plant height, stem diameter, leaf area index at silking, and total N in leaf tissue, were not significantly different among the treatments. These results showed that the application of manures, with or without decomposer, could substitute 25% of the inorganic fertilizers needed by maize plants grown in sandy soil.

Abstract.Potato plants are grown well in the highlands and have the potential to grow at different altitudes. One of the challenges in growing potatoes is pest attack during plantations, especially during the vegetative phase. The study aims to determine the attack intensity of potato pests on Atlantic variety at three different altitudes. This study was conducted in the Sembalun District, East Lombok, in three different locations, namely Sajang Village (at ca. 900 m asl), SembalunBumbung Village (at ca.1000 m asl), and SembalunLawang Village (at ca.1200 m asl) from March to June 2021. The plantations were maintained according to the standard maintenance of potato plantation farmers in Sembalun, and data was collected on a two-week basis. The research method used was an experimental method based on a Randomized Block Design (RBD). The sampling of potato plants was done using systematic random sampling. The results showed that the highest attack intensity of pests in the vegetative phase was observed nine weeks after planting, where the plants were suitable for the foliar pest. Altogether, potato plantation in SembalunBumbung had the highest attack intensity than in SembalunLawang and Sajang village. Further research is needed to examine the resistance of several varieties of potato in different altitudes and different seasons to attack the intensity of pests.

Abstract
One of the main problems of peanut planting in dry land is a lack of nitrogen and calcium availability. Efforts to increase the nitrogen and calcium availability for peanut farming in dry land is needed and one possible approach is by application of Rhizobium and calcium fertilizers. This research was conducted to determine the effect of the application of Rhizobium (Nodulin) and calcium fertilizers on growth and yield of peanut plants in dry land. Two experiments were conducted, one in a greenhouse using a completely randomized design and another experiment in the field using a randomized block design. The treatments were with the application of Nodulin, without Nodulin, with calcium fertilizer and without calcium fertilizer. The results showed that the application of calcium and Nodulin was able to increase the number of root nodules and peanut growth. Nodulin and calcium fertilizers increased the dry pod weight of 2.177 g per 6 m2 or 3.7 tons.ha-1. The application of Nodulin and calcium was also able to increase the nitrogen and calcium content of leaf tissue up to 18.9% and 20.9%, respectively.

Abstract
Taro genetic improvement through polyploidy induction is expected to be tolerant to abiotic stress. Several studies have shown that polyploidy plants have a higher adaptability to dry environments. In vitro selection technique for evaluation of plant tolerance to drought stress can be done by applying polyethylene glycol (PEG) as a selection agent. The aim of the research was to investigate the growth response of diploid and tetraploid taro shoot culture to drought stress using PEG. The experiment was conducted using a completely randomized design with two factors. The first factor was the concentration of PEG at 0, 5, 10, 15 and 20%. The second factor was Bentul taro clones which were 1 diploid clone and 2 tetraploid clones (clones 4.6.3 and 5.4.4). PEG was added to liquid MS medium containing 2 mg/l BAP. Observations of growth variables were carried out every week until the six weeks of culture. Fresh and dry weights, mortality percentage and proline content were determined at six weeks of culture. The results showed that the addition of PEG in liquid medium significantly affected the number of leaves, petiole length, number of roots, fresh and dry weights, as well as shoot mortality percentage. Differences in clones significantly affected the number of leaves, fresh and dry weights. The two factors tested (PEG and clones), gave an interaction on the number of leaves, fresh and dry weights. The proline content in all diploid and tetraploid clones showed an increase with increasing PEG concentration. The LC50 value in diploid clones was 9.82%, in tetraploid clones 4.6.3 and 5.4.4 were 14.14 and 15.45%, respectively. The results showed that PEG at 10% and 15% could be used for in vitro selection to drought stress both for diploid and tetraploid taro.

Published: December 2021

Abstract
The agricultural sector produces solid waste biomass abundantly. However, this biomass potential has not been utilized optimally. Indonesia as the world’s number one producer of oil palm plantations produces enormous biomass potential. Oil palm empty fruit bunches (EFB) are the largest solid waste with a fraction of around 20-23% of fresh fruit bunches. Conventionally, it is only used as plant mulch in plantations areas. However, this biomass can still provide added value to bioenergy products through thermochemical pyrolysis conversion. The study was conducted with EFB raw materials that have been chopped with a size of <2mm, heating rate of 10C/minute with temperature variations of 350°C, 400°C, 450°C, 500°C, and 550°C. The results showed that the EFB pyrolysis at low temperatures produced biochar products, and at high temperatures, it produced maximum product in the form of bio-oil. In the EFB pyrolysis process, biochar with an optimum yield of 36.92% was produced at 350°C, and bio-oil with an optimum yield of 46.60% was produced at a temperature of 550°C.

Abstract
Plastic waste is one of the primary environmental pollutants; in addition to being very large in number, it is also complicated to be degraded by microbes. One of the efforts to overcome plastic pollution is to develop biodegradable thermoplastic (bio-thermoplastic), namely plastic that is easy to form and melts at high temperatures and is easily degraded. This study aims to determine the effect of the type and concentration of thermoplastic forming materials (glycerol and castor oil) on bioplastic composites made from cassava starch with carrageenan. Another goal is to get the best characteristics of the treatment. This study used a randomized block design with 12 treatments derived from 2 types (glycerol and castor oil) and six concentrations (1, 2, 3, 4, 5, 6%) of thermoplastic forming materials. The treatments were grouped into two based on the time of the research. The data obtained were analyzed for diversity, and if it had a significant effect, it was continued with Duncan’s multiple comparison test. The observed variables included mechanical properties, swelling, WVTR, and biodegradation. The results showed that the type and concentration of the thermostatic forming material had a significant effect on tensile strength, elongation, elasticity, WVTR and had no effect on swelling and biodegradation. The bio-thermoplastic composite with the best characteristics was made from starch and carrageenan in a ratio of 25:75 using 1% glycerol with a tensile strength of 33.98 MPa and 1% castor oil with a tensile strength of 35.71 MPa.

Abstract
As a primary source of glucomannan, porang (Amorphophallus oncophyllus Prain) has a decisive role in the food and non-food industry development. However, the naturally high calcium oxalate content in the corm is one obstacle why it is not safe as a food material. This paper describes and discusses the optimizing process to reduce the level of calcium oxalate content and improve the quality of the flour of porang locally grown in Lombok. Porang samples were obtained from the center of growing area in North Lombok. Series of trials were carried out, including treatment using a salt solution, blanching, and fermentation technology. The parameters observed in this study were the calcium oxalate content, moisture content, and the color of porang flour. The results from these trials indicated that soaking in salt solution and blanching technology significantly reduced the calcium oxalate concentration in the flour. However, the oxalate levels in the flour were slightly higher than the quality standard requirement. In contrast, fermentation treatment was not effective in reducing the oxalate level. In general, all treatments significantly reduced the flour-moisture content. Further research is required in order to produce quality local porang flour that meets quality standards.
