Abstract

Sugarcane is one of the most widely cultivated plant commodities in Indonesia. The need for sugar consumption in Indonesia is very high, in 2021 it required 3.2 million tons of sugar consumption. Sugar productivity is strongly influenced by the physical condition of the sugarcane plant which can be influenced by nature, be it weather, temperature, and humidity and the effect of sugarcane plant care in providing plant nutrition and so on. Therefore, an analysis of the health of sugarcane was carried out using the time series comparison method of Landsat-8 satellite imagery with a case study in Pakis District, Malang Regency. In 2017, Pakis Subdistrict contributed 89,793 tons of sugarcane production from a total of 4,001,879 tons of sugarcane production. The productivity level is the age and health of sugarcane. Based on the results obtained using vegetation indices such as the Normalized Different Vegetation Index and Normalized Different Moisture Index and using the Land Surface Temperature parameter, it can be seen that the highest NDVI (Normalized Difference Vegetation Index) and NDMI (Normalized Difference Moisture Index) values occur in February 2022 and the lowest in August 2021 while the highest soil surface temperature occurred in August 2021 and the lowest in February 2022. The sugarcane plants studied had NDVI values ranging from 0.392 to 0.726 and NDMI values ranging from 0 to 0.4. The index value is included in the category of healthy sugar cane. So, if there is a point area outside this value, then there is unhealthy sugar cane. This value is associated with the Pearson correlation so that NDVI and NDMI are very strongly correlated, while the correlation between LST-NDMI and LST-NDVI has a moderate to very strong correlation. However, these parameters need validation in the field to determine the original conditions and the accuracy of the results obtained.

The evaluation of the safety of mining roads is based on three parameters, namely road grade, road width, and road turn angle. Planning for the evaluation of the mine road was carried out through the data collection stage through an aerial photo survey on July 12, 2022, and data processing using Agisoft Metashape and ArcGIS. The output in data processing is in the form of a mine road safety map per parameter. Based on the results obtained in the classification of road grade values, a grouping was carried out with 4 classes, namely the very safe class, the safe class, the warning class, and the hazard class. For road grade parameters, 31% of mining roads at pit A site Alhasanie PT Equalindo are included in the dangerous category. In the width parameter of the mining road, 70% of the status is safe and has been in accordance with the Decree of the Minister of Energy and Mineral Resources No. 1827 K/30/MEM/2018. In the parameters of the turning angle of the mining road, 73% of the status is safe and has been in accordance with the Decree of the Minister of Energy and Mineral Resources No. 1827 K /30/MEM/2018.

Abstract

The rapid development of technology has given rise to innovations and new ways of solving problems. One of them is measuring the situation of surface coal mines. So far, measurements have been made using a Laser Scanner. However, now the Unmanned Aerial Vehicle (UAV) can replace it by considering the aspects of work safety, effectiveness, and efficiency in the field. This study analyzes the influence of the distribution of Ground Control Points (GCP). It compares the measurement method using a Laser Scanner with a UAV in a surface coal mine situation. In addition, this study aims to determine the exact parameters regarding the distribution and number of control points in using UAVs to measure surface coal mining situations. The results showed that the UAV could be used to measure the situation of surface coal with the results of the acquisition parameter research following the 1:1000 PERBIG scale tolerance map, with a tolerance value of <10 cm and the volume difference between the Laser Scanner and UAV is 0.131%. Regarding time analysis and work safety, measurements using UAVs can measure surface mining situations for ± 40 minutes. In addition, personnel do not need to approach the measurement object, so it is better than measurements using a Laser Scanner.

Abstract

Coal is one of the important energy source commodities to carry out industrial activities, which require supporting infrastructure that uses shipping lanes as a means of activity in the delivery of coal from producers to consumers. PT XYZ, in this case as a coal producer, has allocated one of the areas used for coal loading facilities from one of the coal mining located in Gurimbang Village, Sambaliung District, Berau Regency, East Kalimantan Province by using the Berau river channel to the transshipment location in Muara Pantai, Pulau Derawan District, Berau Regency. PT XYZ has obtained a Terminal Permit for Own Interests in the Working Environment and Interest Areas of Tanjung Redeb Port to Support Business Activities in the Coal Mining Sector PT XYZ “TUKS” through the Decree of the Director General of Sea Transportation Number: BX-144/PP 008 concerning Approval Terminal Management for Own Interests in the Work Environment Area and Interest Area of Tanjung Redeb Port to Support Business Activities in the Coal Mining Sector with a capacity of 5,000 DWT. Based on the results of the study of the TUKS flow plan, the position of the general shipping lane, the bathymetry survey of the barge path, the depth of the TUKS pool, the planned loading and unloading volume, the dimensions of the ship that will dock and unload, the frequency of ship visits, the availability of Shipping Navigation Assistance Facilities (SBNP), as well as observations at several points that will become obstacles in shipping navigation, it can be concluded that the development/increase of the DWT TUKS Gurimbang capacity of PT XYZ to support operational activities is still safe enough to be increased to a payload capacity of 8,000 MT with a maximum draft of submerged ships/barges at a depth of -4.70 meters. Therefore, this research can be continued for the preparation of technical review documents as a requirement to fulfill PM 89 of 2018 concerning Norms, Standards, Procedures, and Criteria for Electronically Integrated Business Licensing for the Transportation Sector in the Sea Sector in the process of adjusting DWT (Dead Weight Tonnage) at the Terminal for Self Interest/TUKS PT XYZ in Gurimbang Village.

Abstract

The World Health Organization reports that cataracts are responsible for up to 77.7% of visually impaired individuals in Southeast Asia, with Indonesia having the largest population of such individuals. Cataracts can grow faster in areas exposed to much exposure to ultraviolet rays, such as the Nusa Tenggara Islands, which cover 3 provinces, namely Bali, West Nusa Tenggara (NTB), and East Nusa Tenggara (NTT). The availability of ophthalmologists in NTB and NTT is still lacking. One ophthalmologist serves 261,969 people in NTB and 871,510 people in NTT. This condition contrasts the target distribution of ophthalmologists according to the 2017-2030 Roadmap for Management of Visual Impairment in Indonesia. The development of the shipping industry has had a negative impact on world carbon dioxide (CO2) emissions. The use of a multi-energy hybrid system is believed to be able to effectively reduce energy consumption and emissions from ships. So, in this study, an innovation in the design of an Eye Clinic Vessel with a hybrid electric energy source was designed using the Spiral Design method. This paper aims to obtain operational patterns, payload, main dimensions, technical calculations, lines plan, general arrangements, safety plans, and 3D models. The ship will serve 14 areas with a ratio of ophthalmologists with a population of more than 1:250,000. Two ships will be built, which will be divided into 2 routes, namely the North Route and the South Route. Each area will be served for one week, so 1 round trip of the Eye Clinic Ship takes around 52 days. This ship has a payload in the form of a minimum deck area for clinical facilities of 228.2 m2 and can accommodate 25 patients with a length overall (Loa) of 38.27 m; Width (B) 10 m; Height (H) 3 m; Draft (T) 1.8 m; and Service Speed (Vs) 13 knots. The ship uses 86 units of solar panels with 120 batteries to store electrical energy. This solar panel can save fuel usage up to 54%.
