Abstract

Street vendor (Pedagang Kaki Lima - PKL) is the most incarnation of the informal economy with the biggest role even at the state level. Unfortunately, PKL is blamed as the source of problems and is surrounded by the threat of eviction, which still happened in DKI Jakarta, as the symbol and magnet of development in Indonesia. This study aims to reveal the vulnerability of the PKL in the Golden Triangle of Jakarta and the defensive strategies they carry out. The qualitative method with a case study strengthened by life history for revealing the vulnerability and survival strategy of the PKL household is applied in this study. The result shows the unforeseeable fact that PKL in Triangle Gold of DKI Jakarta potentially can reach an income as same as the regional minimum wage in DKI Jakarta. At the same time, the eviction and number of customers are the PKL’s vulnerability factors. Social capital is essential to start a new job or business as PKL, while strengthened by push and pulling factors to migrate from rural to city. Bridging and bonding with stakeholders through adaptation to the changing rule are the PKL’s main strategies to survive; besides, preserving the identity and norms of PKL boosts the PKL community's adhesion to encounter hard times. Beyond that, resignation value to God and effort for growing are determinant aspects that differ between PKL who have more or less revenue.

Abstract

ABSTRAKSattelite Derived Bathymetry (SDB) merupakan suatu metode di bidang penginderaan jauh yang digunakan untuk mendapatkan nilai kedalaman perairan dengan perhitungan suatu algoritma. Beberapa algoritma telah dikembangkan dalam upaya menghasilkan nilai kedalaman menggunakan metode SDB ini, salah satunya adalah algoritma Stumpf. Algoritma Stumpf memiliki prinsip penyederhanaan operasi hitungan dalam mengekstraksi nilai kedalaman air menggunakan perbandingan dua faktor reflektansi air pada band biru dan band hijau yang memiliki kemampuan tingkat penyerapan terhadap badan air yang berbeda. Prinsip tingkat penyerapan pada tiap band yang berbeda ini menghasilkan perbedaan rasio antar band yang akan mengalami perubahan ketika kedalaman berubah. Namun banyak faktor yang mengakibatkan kesalahan dalam proses pengolahan SDB ini salah satunya pengaruh sifat optis air berupa kekeruhan air. Penelitian ini menganalisis lebih lanjut tentang pengaruh nilai kekeruhan air terhadap akurasi yang dihasilkan dari pengolahan SDB menggunakan perhitungan algoritma Stumpf dengan sumber data citra Landsat-8 OLI/TIRS. Hasil dari pengolahan SDB tersebut kemudian dibandingkan dengan hasil pengolahan SDB yang telah ditambahkan dengan variabel kekeruhan air dari proses uji koefisien regresi terhadap nilai simpangan kedalaman dan nilai kekeruhan air. Pengolahan SDB dapat memetakan kedalaman perairan dengan rata-rata ketelitian (RMSE) yang dihasilkan sebesar 1,531 meter. Dengan menambahkan variabel kekeruhan air, hasil pengolahan SDB memiliki akurasi yang lebih baik dan dapat memetakan kedalaman perairan dengan rata-rata ketelitian (RMSE) yang dihasilkan sebesar 1,462 meter.

Abstract

Fatigue Surgeon merupakan kelelahan yang dialami oleh semua dokter dalam karir bedah. Dalam melakukan operasi, dokter bedah harus melakukan proses bedah dengan berdiri selama beberapa jam, hal ini menyebabkan otot otot pada kaki, punggung, serta leher dokter bedah mendapatkan pembebanan yang kontinyu yang menyebabkan otot otot tersebut kontraksi dan mengalami kekakuan. Kekakuan pada otot kaki ini berdampak jangka panjang pada dokter bedah ditambah dengan pola tidur dokter bedah yang terbatas karena memiliki jam terbang operasi yang tinggi, pola makan, serta terbatasnya waktu untuk olahraga. Pada kasus ini kami berfokus pada dokter bedah laparoskopi yang melakukan operasi selama 2 sampai 4 jam. Hal ini menyebabkan dokter bedah laparoskopi rawan mengalami Fatigue Surgeon. Untuk mengurangi dampak kelelahan ini, dokter bedah laparoskopi menggunakan kursi untuk duduk sambil melakukan operasi, namun kursi yang digunakan merupakan kursi konvensional yang masih kurang nyaman serta minim fitur untuk menunjang kenyamanan dokter bedah. Oleh karena itu dilakukan penelitian ini untuk menganalisis struktur kursi yang telah dirancang yaitu Surgery Smart Chair. Dengan analisis menggunakan solidwork ini akan diketahui apakah struktur kursi sudah cukup kuat bukan hanya dalam proses manufaktur namun juga saat digunakan langsung oleh dokter bedah laparoskopi.

Abstract

This work is an analysis of international political economy studies. This study discusses Indonesia's efforts to increase coffee exports to Japan in the period 2013-2017. The export of Indonesian coffee to Japan is the biggest opportunity for Indonesia in the Asian region. The problem with Indonesian coffee lies in the unstable quality of coffee, this is because 95% of Indonesian coffee plantations are held by the people so that it is difficult to equalize the standard of good quality coffee.            This research uses a liberalism perspective, and is supported by the theory of international trade. This research uses qualitative methods with descriptive analysis. The data collection technique in this research is to conduct library research. Namely analyzing data relating to the problem, with data collection techniques from literature in the form of  books, magazines, newspapers and visits to internet sites and other sources that support research.            This research shows that the efforts that have been made by Indonesia can be divided into two, namely  internal and external efforts. Internal efforts refer to improving the quality, productivity and production of Indonesian coffee with the issuance of the Minister of Agriculture Regulation No. 88 year 2017, the making of ISCoffee, and the 2013-2017 National Coffee Development Activities. External efforts that have been made include efforts to increase coffee exports to Japan through the IJEPA, remove non-tariff barriers to coffee exports to Japan in the case of carbaryl, and promotion of Indonesian coffee exports to Japan. Keywords:International Trade,  Export, Coffee, IJEPA

Abstract

The stability analysis in this mathematical model was related to the infection of the Coronavirus Disease 2019 (Covid-19). In this mathematical model there were two balance points, namely the point of balance free from Covid-19 and the one infected with Covid-19. The stability of the equilibrium point was influenced by all parameters, i.e. target cells die during each cycle, number of target cells at  = 0, target cells infected during each cycle based on virion unit density, effective surface area of the network, the ratio of the number of virus particles to the number of virions, infected cells die during each cycle, the number of virus particles produced by each infected cell during each cycle, and virus particles die during each cycle. In the simulation model, immunity is divided into high, medium and low immunity. For high, moderate and low immunity, respectively, the highest number of target cells is in high, medium and low immunity, whereas for the number of infected cells and the number of Covid-19, it is in the opposite sequence of the number of target cells.

Abstract

Daily activities and occupation can significantly influence health conditions, so a health assessment related to occupational factors is essential to reduce the risk of the disease. One of the leading causes of mortality from cardiovascular disease worldwide is hypertension. This study aims to determine the correlation between the type of occupation toward blood pressure and cholesterol levels in individuals with hypertension. This paper was an analytical observational study with a cross-sectional approach. The population was individuals with hypertension at Depok 2 Public Health Centre, Sleman Regency, Special Region of Yogyakarta. In addition, the sample was 121 respondents with consecutive sampling. The independent variable was the type of occupation, and the dependent variables were blood pressure and cholesterol levels. Instruments were a questionnaire to evaluate the characteristics of respondents and the type of occupation, a digital sphygmomanometer to examine blood pressure, and cholesterol test kits to assess cholesterol levels. The data analysis used the Chi-Square test with α=0.05. Most respondents were female (59.5%) and aged 60-69 years old (47.1%). They worked in the informal sector (81.2%). In addition, they had grade 1 hypertension (52.1%). There was no significant correlation between the type of occupation and blood pressure in individuals with hypertension (p=0.248). In addition, most respondents had high cholesterol levels (50.4%). Furthermore, there was no significant association between the type of occupation and cholesterol levels in individuals with hypertension (p=0.128). In conclusion, the type of occupation is not a risk factor for increased blood pressure and cholesterol levels in individuals with hypertension.

Abstract

Shopee is one of the most frequently visited online buying and selling sites and has a high number of downloads on the play store. However, in the last two years, Shopee has experienced a decrease in the average number of monthly visitors. The purpose of this research is to understand the quality of service provided by Shopee on its website or application. The E-Servqual method is used to measure the gap between attributes and customer service expectations and the Kano model is used to classify attributes and determine the extent to which service attributes meet customer satisfaction. The results of calculations using the E-Servqual method show that the quality of services provided has not met customer expectations, because all attributes have negative gap values. And the results of calculations using the Kano model identify 11 attributes that must be prioritized, due to a linear relationship between attribute performance and customer satisfaction, 11 attributes that need to be maintained, because an increase in attribute performance will result in a very high level of satisfaction and five attributes that need to be improved in order to maximize satisfaction towards customers. Keywords— Service Quality, Customer Satisfaction, Shopee E-Commerce, E-Servqual, Canoe
