Abstract

The presence of groundwater on the mine slopes can disturb the stability of the slope. High groundwater can increase pore pressure which affects the amount of load on the mine slope. In order to lower the groundwater level, it is necessary to have drainage holes to drain water naturally. This study aims to design a horizontal drain installation so that it can lower the groundwater table. The results of this study indicate the existence of an aquifer in the form of sandstones. In this aquifer horizontal drains will be installed. The results of this study are in the form of horizontal drains installation design, namely, the location of the installation of the horizontal drain, the diameter of the boreholes, the distance between the boreholes, the length of the horizontal drains installation pipe, and the angle of inclination of the installation of the horizontal drains.

Abstract

This study aimed to determine the resistance and yield of accessionized determinate hybrid tomatoes (F1) against Tomato Yellow Leaf Curl Virus (TYLCV), and to obtain accessions of determinate tomatoes that are resistant to TYLCV and have high yields.This research method used Completely Randomized Design (CRD) to test the resistance of tomato accessions from TYLCV attack. The second stage of the experiment used a Completely Randomized Block Design (CRBD) to test the yield of  tomato accession at the tolerance level forTYLCV resistance. The treatments consisted of 7 F1 tomato hybrids, namely T-26, T-41, T-121, T-122, T-165, T-175, T-187, and 3 control hybrid namely T-90, Liontin and Betavila. The data obtained were analyzed using analysis of variance (ANOVA) then followed by DMRT (Duncan's Multiple Range Test) at a significance level of 5%. The results showed that the control hybrid T-90 was resistant and the T-122 hybrid was moderately resistant to TYLCV (Experiments stages I and II). The seven hybrids tested (T-26, T-41, T-121, T-122, T-165, T-175, and T-187) had the same weight of fruits as the TYLCV resistant control hybrid (T-90). The superior hybrids on the parameters of weight of fruits, weight per fruits, number of fruit, and fruit diameter were T-122 and T-175. Hybrid (F1) which has resistance to TYLCV and high yield is T-122.

Abstract

Chili (Capsicum annuum L.) is one of the horticultural commodities that have high economic value which is used as vegetables or cooking spices, industrial raw materials, and has export opportunities. The development of superior chili varieties requires a large variety of germplasm that can be used as parents to be crossed with each other to obtain new superior traits. One of the efforts to determine the diversity of plants is to characterize the morphology and production. The purpose of this study was to obtain distinguishing characters among ten genotypes of large chilies, to determine the value of genetic parameter estimators for several genotypes of large chilies and to identify important characters that influence the yield of large chili genotypes. The study was a single factor field experiment in the form of 10 large chili genotypes arranged in a Randomized Completely Block Design (RCBD) with 3 blocks as replication. Genotypes of large chili are: Pilar, Arimbi, Baja, Panex, Forever, Columbus, Gada, Dewa, Rengku, Beautiful. Observation variables are plant height, stem diameter, number of leaves, width of leaves,  leng of leaves, flowering age, harvest age,  fruit length,   fruit weight per plant, fruit diameter, and weight of fruit.. Chili characters that show high genetic diversity are leaf width, while high phenotypic diversity is in fruit weight parameters. High heritability values were found in the characters of flowering age, harvest age, and fruit diameter.

Abstract

SRIKANDI is an information system managed by LPPM that manages research and lecturer service within the UPN "Veteran" Yogyakarta. SRKANDI in its implementation has never been evaluated, therefore in this reserach SRIKANDI was evaluated. The evaluation was carried out using the DeLone & McLean IS Success Model with 150 data obtained from distributing questionnaires to lecturers who had used SRIKANDI. The approach used in this research is quantitative by using regression analysis to test the twelve hypotheses that exist with the successful implementation of SRIKANDI as an information system.

Abstract

Problems related to the sustainability of water resources often occur, both from the impact of the erratic change of seasons, the reduction in water catchment areas, to the many cases of water pollution in Indonesia. However, the main problem of all that lies in the community itself where awareness of the importance of conservation and management of water resources is still low. The selected study was located in Sengi Village, Dukun District, Magelang Regency, Central Java Province. The local community utilizes springs as the main water supply source, but the water management carried out by the community is still classified as less than optimal. Therefore, there is a need for conservation efforts so that the sustainability and function of these springs can be maintained properly. The results of the study showed that spring conservation was carried out by constructing a spring reservoir with a volume of 2 m3 for spring 1 and a spring reservoir with a volume of 5 m3 for spring 2. In addition, a social approach to the community in the local area regarding the preservation of the condition of the springs was also carried out. affixed area

Abstract

The Meratus Mountain in South Kalimantan Province have many geosites variations as geodiversity of National Meratus Mountain Geopark with theme the oldes ofiolite in Indonesia. Meratus Mountain was formed since 200-150ma from collision interaction of eastern part of Sunda Land with Pasternoster Continent who striking towards NE-SW in South Kalimantan Province. This mountain bordered Asam-asam Basin inthe eastern and Barito Basin in the western. The process of multideformation process formed the Meratus Mountain and exposed the ofiolite complex in Indonesia, aged between 200-150 million year ago. This rocks include : dunite, peridotite, pyroxenite, gabro, pillow basalt and chert.

Abstract

This paper describes of three things. First, the Kriging estimation on gold grade which is distributed in the vein. The empirical variogram method based on Matheron classical and robust of Cressie-Hawkins. The two empirical fitting on variogram theory of spherical and exponential equations of weighted least squares and ordinary least squares used. The predictions of six sizes block-Kriging respectively, 15×15, 25×25, 35×35, 50×50, 75×75 and 100×100 based on four variographic models. Second, determine the priority of 24 prediction combinations based on TOPSIS method. Finally, the multiple criterion decision making method namely, 15×15 block Kriging based on a robust empirical variogram of exponential weighted least squares model represents as the best result.

Abstract

Antibacterial bath soap is one of the liquid cleansing preparations made from basic ingredients and is used to clean the skin with the main benefit of effectively killing bacteria and other types of microorganisms so as to minimize skin irritation. Durian fruit skin contains alkaloids, flavonoids, steroids, triterpenoids, and tannins as antibacterial compounds and saponins that can produce foam in water. The main objective of this research is to formulate antibacterial bath soap from durian fruit peel extract. This type of research is an experiment, carried out by Soxhlet extraction of durian skin using 20%, 40%, 60%, 80%, and 96% methanol as solvent. The antibacterial bath soap formula was made at a concentration of 25% durian skin extract including formulas F, G, H, I, and J using a differentiating ingredient, namely the durian skin extract, and was tested for physical and chemical evaluations including organoleptic, homogeneity, pH, foam height, and irritation test. For the results of the remaining durian skin extract, organoleptic tests will be carried out which include  texture, color, and the presence or absence of fungi on the storage time of durian skin extract. The results showed that antibacterial bath soap from durian peel extract had met the requirements for a stable physical-chemical evaluation test which included pH, foam height, and irritation test as well as organoleptic and homogeneity tests for formula F.
