Abstract

The market demand for Cilembu sweet potato is increasing from year to year. Therefore it is necessary to develop Cilembu sweet potato land in other areas to solve this problem, including non-typical Cilembu sweet potato land. Investigations on the distribution of fertile soils are carried out on non-typical agricultural lands so that farmers can assess fertility problems in the soil, which can increase crop productivity. This specialty uses a high-precision agricultural approach to developing geophysical technology, one of which is Electrical Resistivity Tomography (ERT). This research was conducted to determine the characteristics of non-typical Cilembu sweet potato agricultural land in the Cicalengka sub-district. The results show that the resistivity values range from 10 to 800 Ωm, indicating that this area results from weathering of sedimentary rocks. The study results stated that the Cilembu variety of sweet potatoes could be developed on non-typical land in this area by considering the inhibiting factors. Knowing these inhibiting factors is expected to determine the steps in land management as a solution so that non-typical areas can help market demand for the availability of Cilembu sweet potato varieties.

Abstract

Oil palm is one of the plantation crops that provides the largest contribution to Indonesia's foreign exchange with its derivative products in the form of crude palm oil (CPO). The development of CPO consumption as a source of vegetable oil has pushed Indonesia as the largest producer to export CPO to 179 export destination countries in the world and the 10 largest export countries include India, China, Pakistan, the Netherlands, Malaysia, Bangladesh, Egypt, Italy, Spain and Singapore. Indonesia's CPO export volume fluctuates which can disrupt the country's economy. The objectives of this study are: (1) to identify the countries that positively impact Indonesian crude palm oil (CPO) exports among 10 destination countries, namely India, China, Pakistan, the Netherlands, Malaysia, Bangladesh, Egypt, Italy, Spain, and Singapore, (2) to analyse the factors influencing Indonesia's CPO exports to these 10 destination countries, and (3) to examine the impact of geographical distance on Indonesia's CPO exports to these countries. The research was conducted from April to September 2021, using panel data that combines time series and cross-sectional data from 2011 to 2020. The findings indicate that India, China, the Netherlands, and Italy had positive constants, while the remaining six countries had negative constants in terms of Indonesia's CPO exports. The combined effect of Indonesia's gross domestic product (GDP) (X1), geographical distance (X2), and the rupiah exchange rate (X3) significantly increased Indonesia's CPO exports to these 10 destination countries by 73.77%. Geographical distance (X2) had a significant and positive effect, whereas Indonesia's GDP (X1) and the rupiah exchange rate (X3) did not show significant effects and had a negative impact on increasing Indonesia's CPO exports to these destinations

Abstract

The utilization of Jackfruit seeds is still limited as a snack even though it has no less nutritional substances than wheat flour, even the calories and carbohydrate content is lower so it has the potential to be processed into flour and is expected to substitute wheat flour. On the other, public concern about healthy foods with low-fat content has resulted in the need to develop sources of vegetable protein, one of which is oyster mushrooms which are processed into nuggets. This study aims to determine the preference response to oyster mushroom nugget products with jackfruit seed flour substitution The research treatment tested 4 treatment levels of substitution of wheat flour with Jackfruit seed flour, namely P0 (100% Wheat Flour), P1 (80% Wheat Flour + 20% Jackfruit Seed Flour), P2 (60% Wheat Flour + 40% Jackfruit Seed Flour), and P3 (Wheat Flour 40% + Jackfruit Seeds Flour 60%). The results show the substitution of jackfruit seed flour in mushroom nuggets oyster had an effect on the color, aroma, and taste of oyster mushroom nuggets and oyster mushroom nuggets had the best preference in t 20% substitution treatment.

Abstract

Interpretation of geomagnetic anomaly data is challenging, due to the influence of the Earth's dipole magnetic field. In this study, we investigate the significance of employing methods to transform dipole anomalies into monopoles, aiming to enhance the interpretability of the data. Four methods were examined: Reduce to Pole (RTP), Reduce to Equator (RTE), and Pseudo-Gravity. The RTP method was implemented using general equations for RTP, Pseudo-inclination (PI), and Nonlinear thresholding (NTRTP). The computation programs for RTP and RTE were developed using the Matlab programming language. Synthetic models were constructed to investigate the effects of inclination values, object dimensions, and positions on the resulting magnetic anomaly response. The result shows that NTRTP methods give the best result with coefficient correlation >0.9. It can be used in every condition (low or high inclination). The implementation was conducted utilizing magnetic data in the Gunung Pandan geothermal area. The application of the reduced to the pole (RTP) technique on the field data successfully remove the dipole effects, and make interpretation process easier. Based on RTP map, the range of anomaly values spanning from -800 nT to 1000 nT. High anomalies were observed at the Gunung Pandan site, indicative of a probable intrusion of andesitic igneous rock.

Abstract

Bioethanol derived from cassava has the potential as an alternative energy material because cassava plants contain starch, sugar or cellulose which can be used in the process of making alternative and environmentally friendly fuels. This study aims to make bioethanol from cassava starch. This research method starts from material preparation to the process stage consisting of the fermentation process, distillation process, and the final stage, namely testing ethanol content and adding fuel. 5 kg of cassava is used to produce 98 ml of bioethanol distillation with 16% rendition. The combustion test was carried out to obtain a comparison of the calorific value between the fuel mixture - Bioethanol and fuel -Alcohol, Mixing partalalite - Bioethanol 1: 19 (95% partalaite: 5% Bioethanol) and fuel - Alcohol 1: 19 (95% partalite: 5 % alcohol). The results of the research obtained the calorific value of combustion of the partalalite - alcohol mixture: 11,649.48 kcal/kg, while for the partalalite - bioethanol mixture: 11,486.15 kcal/kg. So that the higher the concentration of ethanol mixed in partalite, the higher the calorific value.

Abstract

The city of Bima is an area that produces quite a lot of bricks with favorable natural conditions, most of the area consists of rice fields and has a soil texture suitable for making bricks. Red brick is the most widely produced type of brick with a total of 20,000 bricks per month and its use has a negative impact on the environment because it produces carbon dioxide (CO2) emissions which pollute the air and contribute to the greenhouse effect which causes global warming, also as a result of burning bricks. . Based on this, researchers are trying to conduct research related to building materials in Bima City in the form of brick innovations with more environmentally friendly basic materials. The research was carried out using a true experiment and cross sectional approach using conventional bricks as a standard for quality comparison. Descriptive analysis was chosen as the method of analysis in this study. From the results of brick quality tests, all brick formulas met the requirements for water content (<15%), four of the six formulas met the compressive strength requirements based on SNI. The average compressive strength of the four formulas is >5 MPa and meets the Indonesian national brick breaking strength standard (SNI-0021-78). The most significant advantage seen from brick products without burning is the lower water content than conventional bricks and is more environmentally friendly because it uses natural materials and is obtained at competitive prices
