Increasing consumer awareness of the authenticity of products has led to a demand for rapid measurement methods to support the traceability of high‐value commodities. In this research, a front‐face method was used to obtain fluorescence excitation–emission matrix fingerprints of patchouli oil samples from different geographical origins in Indonesia. Principal component analysis (PCA) was then used to explore the excitation–emission matrix (EEM) data structure of the samples, and 3D eigenvector value thresholding was used to discriminate important variables. It was found that there were five important EEM regions representing the sample variation. A decision‐tree model with a subset of two important regions, i.e. regions 1 and 3, was then developed for the classification of patchouli oils from different Indonesian islands. These results show that front‐face fluorescence spectroscopy has the potential to be used as a supporting tool for the discrimination of the geographical origin of patchouli oils.

The limited land owned by the community in urban areas such as RT 04 and 06 RW 07 in the Tegalrejo village in Salatiga makes the Family Medicinal Cultivation Facility (SABDA TOGA) one of the solutions so that the com-munity can continue to grow crops that can be used for daily needs. Through community service (PM), training on how to apply aquaponics planting technology, herbal plants in sacks (taherlarung) and fermentation of organic liquid fertilizer as a TOGA planting model in urban communities. The method used is making demonstration plots for the application of organic aquaponics planting media technology, taherlarung, and fermentation of or-ganic liquid fertilizer for TOGA plants in the partner environment, carrying out data collection on TOGA plants in the community, and conducting socialization in the community. The results of this dedication show that aqua-ponics planting media technology can be combined with a fish pond so that it can produce organic TOGA. Aqua-ponics technology can be automated and can also take advantage of the people's narrow land with a vertical media arrangement pattern. TOGA planting in taherlarung can be increased to become an alternative way of decorating the road. While liquid organic fertilizer is very potential to be produced in large quantities because it utilizes household organic waste with a fermentation period of approximately 1 month. Some people already have TOGA plants but do not know the benefits and how to use them. This PM activity shows that aquaponics, taherlarung and fermentation of organic liquid fertilizer are suitable for TOGA weaving in urban communities. Some urban community groups tend to not know and utilize TOGA.

Non Linear Frequency Modulation (NLFM) method can suppress the peak sidelobe level without additional windowing function. NLFM doesn’t require any weighting function because it has inbuilt one. NLFM has a variable frequency deviation function due to the relation between frequency and time of the signal which is not linear so that it is possible to suppress of peak sidelobe level. This paper studies the characteristic of various NLFM waveform, such as NLFM Tri Stage Piece Wise (TSPW), NLFM S, and NLFM Taylor. The study of Pulse Compression of NLFM waveform consists of three aspects. First, analysis of pulse compression performance. Second, analysis of background noise. Last, analysis of Doppler effects. The simulation is done using Matlab software. The lowest value Peak Sidelobe Level (PSL)of NLFM TSPW is about -20 dB while NLFM S and NLFM Taylor are about -32 dB and -39 dB. Additive White Gaussian Noise (AWGN) and Doppler Effect influenced the value of PSL for each NLFM waveform. NLFM Taylor has the best NLFM waveform when the Doppler Effect and AWGN cause the value of PSL become high. Comparison between NLFM Taylor and Linear Frequency Modulation(LFM) is done in radar surveillance applications to analyze the detectability performance where the condition of Radar Cross Section (RCS) for each target has different significant value. The three targets are commercial airplanes, helicopter and fighter. For detectability performance, NLFM Taylor can detect more clearly than LFM conventional.

Earthquakes are events of the movement of the earth due to the sudden release of energy in the earth which is marked by the breaking of the rock layers in the earth’s crust. Indonesia is located in an earthquake-prone area where three tectonic plates meet, namely the Indo-Australian plate, the Eurasian plate and the Pacific plate. Realizing the threat of an earthquake that could occur at any time, the Indonesian government took the initiative to take measures to prevent the risk of damage to infrastructure that could occur due to an earthquake. This paper presents an analysis of the earthquake resistance of a lecture building at an educational institution in the city of Yogyakarta with the equivalent static method and the dynamic response spectrum method. The purpose of this paper is to provide an overview of whether construction projects that have been implemented using SNI 1726-2012 are analyzed and compared with the latest standards, namely SNI 1726-2019, whether the building construction still meets earthquake resistance. The results of the comparative analysis of the equivalent static method and the dynamic response spectrum method show that the building under study does not meet the strength and resistance to earthquakes based on SNI 1726-2019, so it is necessary to strengthen the structure of the building under study.

Continuous exposure to an area with a sound above the threshold level is one of the triggers for noise pollution in public spaces. Public spaces are spaces where people of all ages gather for leisure activities, recreation, etc. The purpose of this study was to find the average dBA value of noise, community perceptions regarding the comfort of sound in coastal public spaces, and the relationship between the dBA value and the existing sound comfort standards. The focus of this research is to contribute to a public space that is free from noise pollution.

The results found noise numbers in the range 77.4 – 80.2 dBA, this value has exceeded the required standard of 50 dBA, and the results of the perception are also supportive, which is dominant in public perception. It means that coastal public spaces in the Boboca monument area have been exposed to noise pollution.

Dalam kehidupan manusia tidak terlepas dari adanya Gas karbon monoxida, Gas CO, Gas Karbondioksida CO2,dan Gas Metana yaitu hidrokarbon CH4. Gas CO yang tidak berbau sangat berbahaya bagi manusia yang menghirup udara secara langsung karena kekurangan oksigen dan menyebakan lemas karena pengaruh gas beracun. Metana (Methane) adalah hidrokarbon paling sederhana yang berbentuk gas. Metana murni tidak berbau, tidak berwarna, extremely flammable (sangat mudah terbakar) , asphyxian (mampu menggeser oxygen), non toxic dan non corrosive. Pembakaran satu molekul metana dengan oksigen akan melepaskan satu molekul CO2 (karbondioksida). Gas CO2 bersifat asphyxiant yaitu pada konsentrasi yang tinggi dapat menggantikan oxygen di udara, dan menimbulkan sesak napas dan rasa tercekik. Bahaya Gas Metana adalah salah satu gas rumah kaca atau (greenhouse gas) disingkat GHG dan merupakan penyebab terbesar pemanasan global dalam beberapa tahun terakhir. Dari fenomena diatas pada penelitian ini bagaimana perancangan alat yang digunakan untuk mendeteksi besar kandungan dari gas CO, CO2, dan CH4 di udara pada suatu ruangan tertutup. Alat ini menggunakan sensor gas MQ 135 dengan tipe berbeda berdasarkan sentivitas dari ketiga gas tersebut. Pengendali utama alat dengan mikrokontroler ATMEGA 8535 yang digunakan memonitor kadas gas yaitu output tampilan LCD,indikator LED dan blower sebagai netralisir udara bersih dari polutan gas berbahaya. Dari hasil pengujian alat dengan menggunakan sensor MQ 135 terhadap kandungan gas CO, CO2 dan CH4 data yang diterima oleh sensor masih dalam satuan ppm dan dikonversi dalam bentuk persen berdasarkan maksimum ppm detection range oleh masing-masing sensor. Sensor CO dengan maksimum range 2000 ppm, CO2 dengan maksimum range 10000 ppm, dan CH4 dengan maksimum range 20000 ppm. Hasil dari lima kali pengujian masing-masing kadar gas pengukuran sensor CO, CO2, dan CH4 menunjukan nilai rata-rata untuk gas CO 0.0562 % dengan nilai tegangan 0.428 Volt, untuk Gas CO2 nilai rata-rata 0.0127 % dengan nilai tegangan 0.476 Volt, dan nilai rata-rata untuk gas CH4 0.00488 % dengan nilai tegangan 0.364 Volt. Dari data hasil pengukuran sensor CO, CO2, dan CH4 dapat disimpulkan bahwa tegangan yang didapat dari hasil pengukuran dipengaruhi oleh jumlah kadar gas berbahaya. Semakin tinggi kadar gas maka semakin tinggi pula tegangan yang diperoleh masing-masing sensor. Kata kunci: Sensor Gas MQ 135, mikrokontroler ATMEGA 8535, Gas CO, CO2, CH4.

Pumice Breccia is a natural material which is available in a vast deposit of volume in Indonesia, especially in Yogyakarta area.

The results of this study are to produce elections held with the District E-Voting.

The precision agricultural development paradigm leads to the effort of controlling environmental parameters based on the suitability of needs, responses, and shallot crop performance. The distribution of temperature and air flow pattern have been required for growing. Furthermore, the temperatures less than 20°C is suitable or comfort for flowering initiation of shallot. Therefore, CFD simulation has been applied to compute temperature distribution and pattern with two alternate positions of air conditioners. The simulated domain is a chamber from container 40 ft with dimension of 672 × 212 × 261 cm. The room is equipped with 6 planting media shelves in the form of a substrate with a drip irrigation system. Each layer of the plant shelf is equipped with 4 units LED @ 20 W. The cooling source in the cultivation room comes from 2 AC units with a capacity of 2 pk. The position of the AC is placed on the front and rear walls with two different combinations, namely the top-top and top-center. Numerical approach was carried out to verify the results of the calculation, which used the grid convergence index with the number of cells around 1.7 million and the result of simulated air velocity value reached 0.27-0.30 ms-1. The air inside the chamber was cooled until the air temperature reaches 16-18 ° C by using 2 standard AC units. The top-top AC position was the best position with an air temperature uniformity of more than 99.5% for the entire shelf layer.

K-means a fairly simple and commonly used cluster of clusters to partition datasets into multiple clusters. Distance calculations are used to find similar data objects that lead to developing powerful algorithms for datamining such as classification and grouping. Some studies apply k-means algorithms using distance calculations such as Euclidean, Manhattan and Minkowski. The study used datasets from gynecological patients with a total of 401 patients examined and as many as 205 patients detected cervical cancer, while 196 other patients did not have cervical cancer. The results were shown with the help of confusion matrix and ROC curve, accuracy value obtained by 79.30% with ROC 79.17% on K-Means Euclidean Metric while K-Means Manhattan Metric by 67.83% with ROC 65.94%. Thus it can be concluded that the Euclidean method is the best method to be applied in the K-Means Clustering algorithm on cervical cancer datasets.

From an economic perspective, rice is an important crop. The System of Rice Intensification (SRI) is known as a rice production technology with a high economic value. The economic value varies depending on different implementations of water level in the SRI paddy field. This study was conducted to determine the best water level for SRI paddy cultivation based on its economic value regarding paddy field ecosystem service. In this study, SRI paddy rice was cultivated in experimental pots, and the water levels were regulated at -12, -7, -5, -3, 0 and +2 cm from the soil surface by using Mariotte tubes. The economic value can be calculated using the Total Economic Value (TEV) framework, namely, by considering the amount of irrigation water used, the reduction of greenhouse gas emissions and the yields. The value is then optimized by Excel solver to maximize the balance in economic value as the objective. The water level was set as a changing value with the constraint not less than -12 and not more than +2. This analysis found that the best water level for SRI paddy cultivation is -5.88 cm from the soil surface based on its economic value (49.708 million IDR per hectare).
