Patrol Ship Design to Guard the Natuna Seas
Get PDFNatuna is one of the regencies in the Riau Archipelago Province, the area of Natuna Regency is 224,684.59 km2 with a land area of 2,000.85 km2 and an ocean area of 222,683.74 km2. According to the Ministry of Maritime Affairs and Fisheries, Natuna occupies the first position for the purpose of exporting fishery products from the SKPT location (Integrated Marine and Fishery Centers in Small Islands and Border Areas), namely marine fisheries resources reaching more than 1 million tons per year. The extent of Natuna waters and the large potential of existing capture fisheries resources cause the Natuna waters to be included in the Fisheries Management Area (WPP 711) which is prone to illegal fishing activities. It has been proven recently that in the waters of North Natuna there are coast guard ships from foreign countries escorting fishing vessels belonging to their countries that are carrying out illegal, unreported, and unregulated fishing activities. The purpose of this research is to design a patrol ship to carry out security missions around the Natuna waters. The method used in this design is the Parent Design Approach method. This method is known in designing ships, namely by taking a comparison ship that has the same characteristics as the ship to be designed. The main dimensions of the ship obtained in this final project are Lwl = 50.2 m, B = 9.32 m, H = 4.45 m, T = 3.5 m, Vs (max) = 25 Knots, Crew = 40 Indonesian navy. Armaments used on this ship are Oto-Melara 76/62SR 76 mm, Oerlikon Millennium 35 mm, RWS Machine Gun, and SS1-V1 Kal hand rifle. 5.56 mm

Based on data obtained from the Central Statistics Agency of South Sulawesi Province, there was a significant increase from 2010 to 2021, for example, household consumption expenditure in 2010 was 100 and in 2021 it rose to 167 and that applies to all components of expenditure. This type of research uses a quantitative research approach. The data used is secular data obtained from the BPS publication of South Sulawesi Province, where the object of research is Gross Regional Domestic Product by expenditure with 8 sectors for the last 12 years, namely from 2010-2021. All expenditure component variables are eligible for factor analysis because they have met the data adequacy test and the data freedom test, and only 1 factor is formed. The expenditure component in GRDP has a very strong relationship because it has a value > 0.5 which can be said that the Expenditure Component consists of Household Consumption, LNPRT Consumption, Government Expenditure, Gross Fixed Capital Formation, Changes in Inventory, Foreign Exports, Foreign Imports, Inter-regional Net Exports affect the economic growth rate of South Sulawesi Province. The most dominant variable is Gross Fixed Capital Formation because it has a greater correlation value among other variables

Adaptive Assessment and Guessing Detection Implementation
Get PDFComputerized adaptive testing (CAT) is a context-based adaptive assessment. However, the assessment result may not be valid because the examinee might cheat or guess the answers. Although there are many guessing detection methods, there are not many discussions about their implementation into CAT. Therefore, this paper presents an example of a modification of an existing software so the newly modified software can detect guessed answers and be able to select questions adaptively. The system can detect assuming behavior by recording the examinee’s answer time. Also, the designed system can like questions adaptively by connecting Fuzzy logic, which calculates what level the question should select for the next iteration. The system is responded well by elementary and college students. A total of 56.6% felt the system was straightforward to use. The detection methods can detect guessing behavior of about 73%. However, the system’s sensitivity is low if the method is forced to classify answers which answered in a long response time / general guessing. Nevertheless, when we limit the data classified within 10s response time (rapid-guessing), the method’s sensitivity rises to 68.78%
Simple Investigation on the Optical Properties of Carbon Nanodots Using Lasers and a Lux Meter
Get PDFCarbon nanodots (Cdots) have excellent optical properties. This study aims to investigate scattering and absorption of Cdots via simple exposure of ultraviolet (UV)/violet, red, and green lasers. The experiment was conducted by preparing the Cdots from cajuput oil distillation wastes as the precursor. The solid wastes were dried under the sun, grounded into powder, filtered, and carbonized inside an oven at 250 oC for one hour. The carbonized powder was then mixed with distilled water, left for a night, and then filtered again so that the Cdots solution was obtained. Here, the mass of the precursor was varied. The Cdots samples were characterized using ultraviolet-visible (UV-Vis) and photoluminescence (PL) spectroscopies, and also particle size analyzer (PSA). The lasers were directly exposed to the Cdots samples. A digital lux-meter was used to measure the intensity of the lasers transmitted from the sample. The angle of the lux-meter was varied on a circular track. The sample was on the center of the track. The UV-Vis characterization showed two peaks at 217 nm and 270 nm, and a tail extending to the visible region. The PL characterization showed an intensity peak at 509.57 nm, which confirms the cyan luminescence of the Cdots. The PSA characterization indicated that the size of the Cdots was 1.04 nm. Moreover, at an angle of 0o, the UV wavelength was strongly absorbed by the Cdots in accordance with the UV-Vis characterization result. The intensity of the green laser also dominates as it was less absorbed and strongly scattered by the Cdots
