Abstract

The landscape in the Terrace Hill Sentul City area of Bogor Regency is at level + 280 to + 307 above sea level. is a contoured area, planned to be used as a housing area with a Down Hill and Up Hill model. For this reason, it is necessary to carry out land preparation in the form of Excavation (Cutting) and Fill work, while because the condition of the sloping land and the type of soil in the form of silt has the potential to experience landslides, for this reason, slope reinforcement work is needed. This area also borders a residential area so that an evaluation needs to be carried out whether the land preparation work does not interfere with the area owned by local residents. Based on the results of calculations and analysis of slope stability using the Splicing method and the Plaxis program, it was obtained that in the Terrace Hill area, slope stability engineering needs to be carried out. Handling of this housing area can use the construction of retaining walls from stone or concrete cyclops, placement of piles of sacks filled with soil, installation of gabions or using bamboo cerucuk, dolken and bored pile poles

Abstract

Reactive powder concrete is a new type of concrete that has ultra-high compressive strength, the components of which are very fine powders that have high silica content. Reactive powder concrete has high compressive strength and ductility, which has the potential to replace steel materials in construction work, and has a very large opportunity for construction materials in Indonesia. In this study, 3 types of strength tests were carried out, namely compressive strength tests, splitting tensile tests and flexural strength tests. Compressive strength tests were carried out on cubes measuring 5 cm x 5 cm x 5 cm with cylinders measuring 10 cm x 20 cm, and splitting tensile strength on cylinders measuring 10 cm x 20 cm and flexural strength were carried out on reactive powder concrete measuring 4 x 6 x 60 cm and reinforced beams measuring 5 x 9 cm x 140 cm with the addition of 0.5% bendrat fiber from the concrete volume. The treatment of test objects for cubes and cylinders was carried out by curing with ordinary water. From the results of the tests that have been carried out, it was concluded that type II cement can increase the usual compressive strength of 43.9 MPa. For the splitting tensile strength of concrete using type II cement is 3.95 MPa higher than the use of type I cement of 2.23 MPa. The flexural strength of reactive powder concrete with 0.5% bendrat fiber is 23.44 MPa and reinforced concrete with 0.5% bendrat fiber is 61.93 MPa

Abstract

which is in nature both ossifying and closing ground surface, causes the decline of ground water infiltration. Some efforts to enlarge ground water infiltration have already been done, for example, by making infiltration wells and bioporic infiltration holes. Earthworms naturally do some activities which contribute to make ground water infiltrate. Due to this fact, a research needs conducting on bioporic infiltration holes of earthworms. This research was performed in Sukoharjo, Surakarta from September 2007 up to July 2008. The study aimed to search the diameter and amount of width units of bioporic infiltration holes of earthworms. The number of infiltration holes of earthworms was counted on the basis of measurement plots of 50 cm x 50 cm. The plots, 20 in number, were placed on a piece of land randomly. Each hole of earthworms (biopore) in every plot was measured to find its diameter. The result of the research showed that the average diameter of bioporic infiltration holes of earthworms was 4,58 mm, and there were 20 holes found in every square meter of land. The bioporic infiltration holes of earthworm could extend the infiltration area of ground water as many as 873 times.

Abstract

The development of information and communication technology has experienced very rapid development, this also affects the services provided by operators in order to support the speed of development of information and communication technology. Information and communication technology cannot be separated from the existence of BTS (base transceiver station) antennas which are a problem, the construction of too many telecommunications tower infrastructure without planning will cause problems that are not good for the spatial planning and beauty of Bogor City. In determining zoning, data is needed from all telecommunications towers standing in Bogor City, then analyzed using the AHP (Analytical Hierarchy Process) method. In order to make it easier to map telecommunications towers, it is combined with GIS (Geographic information system) with the hope that it can be a recommendation for decision making by the Bogor City government. In determining the zoning, namely by taking into account the distance of the tower and data from the coordinate point where the tower stands. Determination of zoning with a range of 5 km each, so that 4 zones are obtained, namely zone-1 at a distance of 5 km for the Central Bogor City sub-district area, zone 2 at a distance of 5.1 km -10 km for the West, East and North Bogor city areas, Zone-3 at a distance of 10.1-15 km for the South Bogor City and Tanah Sareal areas and Zone-4 at a distance above 15.1 km for parts of the South Bogor City and Tanah Sareal areas.

Abstract

The present study investigates the stimulant and hematological effects of combined beetroot (Beta vulgaris L.) and apple (Malus pumila Mill.) juice on the physical endurance and hemoglobin (Hb) levels of Sprague Dawley rats. Adequate Hb concentration plays a critical role in oxygen transport and energy metabolism during physical activity. Thus, natural stimulant sources rich in bioactive compounds were evaluated as potential alternatives to synthetic energy supplements. Twenty-five male rats were divided into five treatment groups (n = 5): three groups receiving different ratios of beetroot and apple juice (1:1, 2:1, and 1:2), a negative control (CMC-Na 0.5%), and a positive control (caffeine 20 mg/200 g body weight). Stimulant activity was assessed using a rotarod endurance test, while Hb levels were measured by the Sahli method using a hemometer. The results demonstrated that the combined beetroot and apple juice significantly enhanced both endurance duration and hemoglobin concentration compared to the negative control (p 0.05). The optimal stimulant and hematopoietic effects were observed in the 2:1 beetroot-to-apple ratio, corresponding to doses of 5.6 g and 0.63 g per 200 g body weight, respectively. This combination yielded prolonged rotarod retention time and elevated Hb levels up to 18.5 g/dL, exceeding baseline and control values. The observed enhancement is attributed to the synergistic effects of bioactive constituents such as iron, potassium, flavonoids, and vitamin C, which facilitate oxygen transport, neuromuscular coordination, and erythropoiesis. These findings indicate that beetroot–apple juice exerts a physiological stimulant effect while improving hematological parameters without the adverse effects commonly associated with synthetic caffeine-based stimulants. This study highlights the potential of functional plant-based beverages as safe natural ergogenic aids for improving endurance and blood health.

Abstract

Podocarpus blumei is a slow-growing coniferous tree species belonging to the Podocarpaceae family, widely utilized for timber, handicrafts, and traditional medicine in Indonesia. However, its propagation remains limited due to seed dormancy and low germination rates. This study aimed to determine the most effective combination of seed dormancy-breaking techniques and wood vinegar concentrations to optimize seed germination and early seedling growth. The experiment was conducted using a completely randomized design with factorial treatments involving different dormancy-breaking methods—scarification, soaking in coconut water, and hot water—and variations in planting media (soil, cocopeat, and husk charcoal). Subsequent seedling treatments involved applying wood vinegar at four concentrations (0%, 0.1%, 0.2%, and 0.3%) for eleven months. Results showed that P. blumei seeds had an average moisture content of 40.14%, classifying them as recalcitrant. Among the dormancy-breaking treatments, scarification produced the highest germination rate (90%), maximum growth potential (92%), and fastest germination period (51 days) in soil–cocopeat–husk charcoal media. Application of 0.2% wood vinegar significantly increased stem diameter (0.8 mm), leaf number (19), and biomass accumulation, indicating enhanced physiological activity. In contrast, higher concentrations (≥0.3%) did not further improve seedling performance. The findings demonstrate that integrating mechanical scarification and moderate wood vinegar concentration (0.2%) effectively enhances the germination and early vigor of P. blumei seedlings. This study provides a practical propagation approach for conserving and sustainably managing Podocarpus blumei populations, contributing to improved silvicultural practices for native forest species in Indonesia.
