Penerjemahan sebagai Media Pekabaran Injil Middelkoop Ditinjau dari Perspektif Hermeneutika Hans Georg Gadamer
No full textThis is paper is a hermeneutical approach to Peter Middelkoop’s Bible translation in West Timor, East Nusa Tenggara. By way of Gadamer’s hermeneutical thought, the author deduced that evangelism is always impacting either the mission activities or the site of mission. Since any achievement of evangelism, which implicated the local languages is not a sole accomplishment of mission institutions, such as Netherland Zending Genotschaf (NZG), but an outcome of the engagement between the missionaries and the existing culture
Initial Handling Of Tuna As Raw Material For Canned Fish
No full textThis study aims to determine histamine levels and organoleptic results from fresh tuna and frozen tuna. The data obtained are presented in the form of histograms and tables are then discussed. The results showed that histamine levels in 3 fresh tuna samples, namely S1, S2, and S3 samples, were below 30 ppm. 3 samples of frozen tuna, namely samples B1, B2, and B3, are also below 30 ppm which is the standard set by the company. This shows that samples from fresh tuna have a lower amount of histamine levels than frozen tuna, so they still meet the export standards of the Food and Drugs Administration (FDA) which is 50 ppm (FDA, 2011) and meet the Indonesian National Standard, SNI 2729: 2013 (BSN, 2013) which is a maximum of 100 ppm. For organoleptic results on 3 samples of fresh tuna and frozen tuna, namely samples 1, 2, and 3 showed organoleptic results from the appearance of the eyes, gills, appearance of body surface mucus, organoleptic results of meat, organ results of odor, organoleptic results of texture have a good value . This shows that samples from fresh tuna and frozen tuna are of good quality and still meet the Indonesian National Standard (SNI 2729:2013) regarding sensory criteria in fish.

Leveraging MobileNet, InceptionV3, and CropNet to Classify Cassava Plant Disease
No full textAbstrakSingkong adalah tanaman yang tumbuh di sub-saharan Africa dan sering dijadikan sumber karbohidrat bagi manusia. Namun, tanaman singkong tersebut memiliki banyak penyakit yang dapat mengancam ketersediaan bahan makanan bagi jutaan orang. Terdapat banyak upaya dan penlitian yang menggunakan kecerdasan buatan dalam bentuk computer vision agar dapat membantu petani mendiagnosa apakah tanaman singkong mereka sehat atau tidak hanya dengan mengambil gambar dari daun tanaman mereka. Pada publikasi ini, penulis melatih tiga jaringan saraf artifisial yang bernama CropNet, MobileNet, dan InceptionV3 untuk dapat mengklasifikasikan gambar-gambar berupa penyakit tanaman singkong. Pembaruan yang dibawa penulis adalah dengan membuat sebuah algoritma gabungan yang mengkombinasikan hasil prediksi dari ketiga jaringan saraf artifisial yang telah dilatih guna mendapatkan hasil prediksi yang lebih akurat. Ternyata, metode penggabungan algoritma ini mampu memberikan nilai akurasi lebih tinggi 6.8% ketimbang nilai rata-rata akurasi dari masing-masing model.Kata kunci: pembelajaran mesin, visi komputer, klasifikasi gambar, jaringan saraf artifisial, kecerdasan buatan, penyakit tanamanAbstractIn sub-Saharan Africa, cassava is widely grown and considered to be a large source of carbohydrates for human food. However, the plant is plagued with diseases which can threaten food supply for millions of people. By using computer vision, researchers attempted to create an image classification model that can tell farmers whether the plant is sick or not by taking pictures of their leaves. In this short paper, the author attempts to train three Convolutional Neural Network: CropNet, MobileNet, and InceptionV3 that can classify cassava plant diseases based on visual data. As a novelty, the author creates an ensemble voting classifier that combines the prediction of CropNet, MobileNet, and InceptionV3 to create a better prediction. Turns out, creating an ensemble voting classifier enables us to achieve an accuracy score which is 6.8% higher than the average individual scores of each model.Keywords: machine learning, computer vision, image classification, convolutional neural network, artificial intelligence, plant disease
Exploring the experiences of Zimbabwean migrant educators teaching in the Western Cape, South Africa
No full textThesis (MA)--Stellenbosch University, 2024.ENGLISH ABSTRACT: This study sought to explore the experiences of Zimbabwean migrant educators teaching in Western Cape, South Africa. A qualitative approach was used to interview 10 Zimbabwean educators. Qualitative thematic analysis was applied to the data and revealed three main
themes: dissatisfaction with bureaucratic processes, unnecessary red tape, and permits; the precariousness of contract work; and the manifestation of otherness anti-migrant sentiments. The themes also revealed the extent of how the lives of migrant educators have become very volatile living in South Africa and this has produced a lot of uncertainty about their future in this country. Their situation is made worse by government bureaucracy pertaining to permits
required for Zimbabweans in order to live and work in South Africa. These strenuous and often slow bureaucratic procedures often leave Zimbabwean migrants hopeless. This study recounts the experiences of 10 Zimbabwean educators in South Africa. The author of this study is similarly a Zimbabwean migrant educator who teaches in the Western Cape. Her contributions
to the data were made in the form of a personal journal that reflected on her own experiences. These experiences formed part of the analysis presented in this research.AFRIKAANSE OPSOMMING: Hierdie studie het gepoog om die ervarings van Zimbabwiese migrante onderwysers wat skool gee in die Wes-Kaap, Suid-Afrika te verken. 'n Kwalitatiewe benadering is gebruik om onderhoude met 10 Zimbabwiese onderwysers te voer. Kwalitatiewe tematiese analise is op die
data toegepas en het drie hooftemas aan die lig gebring: ontevredenheid met burokratiese prosesse, onnodige rompslomp en permitte; die onsekerheid van kontrakwerk in Suid-Afrika; en die manifestasie van andersheid wat anti-migrant sentimente veroorsaak. Die temas het ook die omvang van hoe wisselvallig die lewens van migrerende onderwysers wat in Suid-Afrika
woon onthul en hoe dit baie onsekerheid oor hul toekoms in hierdie land veroorsaak. Hul situasie word vererger deur regeringsburokrasie met betrekking tot permitte wat nodig is vir Zimbabwiërs om in Suid-Afrika te kan woon en werk. Hierdie strawwe en stadige burokratiese prosedures laat Zimbabwiese migrante dikwels hopeloos. Hierdie studie vertel die ervarings
van 10 Zimbabwiese opvoeders in Suid-Afrika. Die skrywer van hierdie studie is insgelyks 'n Zimbabwiese migrante-onderwyser wat in die Wes-Kaap skool gee. Haar bydraes tot die data is gemaak in die vorm van 'n persoonlike joernaal wat oor haar ervarings reflekteer het. Hierdie ervarings het deel gevorm van die analise wat in die navorsing aangebied word.Master
ANALISIS UNJUK KERJA AIR CONDITIONING (AC) SPLIT 2 PAARDE KRACHT (PK) MENGGUNAKAN REFRIGERANT 22 DENGAN MUSICOOL 22 TERHADAP KONSUMSI LISTRIK
No full textThe total use of electrical energy in a building or structure, one of them is the use of an air conditioning (AC) system. There are still many uses of air conditioning (AC) systems based on halocarbon refrigerants (R-22) in a building or structure. Refrigerant 22 is a type of halocarbon refrigerant that is widely used in Split ACs. The author conducted research on an LG 2 PK AC by replacing the refrigerant which was still based on Refrigerant 22 with the hydrocarbon refrigerant Musicool 22, then the data results were analyzed to determine the performance of the AC. From the results of the refrigerant retrofitting carried out on March 1, 2022, it was 1,715 Watts. After replacing the refrigerant type from refrigerant 22 to Musicool 22 refrigerant, the electric current dropped to 1,305 Watts in April 2022, 1,352 Watts in May 2022 and 1,346 Watts in June. so that the electrical power efficiency was obtained by 369 Watts and the percentage of electrical power savings was 21.51% compared to March 2022. An alternative to replace halocarbon-based refrigerants in the Split air conditioning (AC) system is hydrocarbon refrigerants, this is a solution in terms of using more environmentally friendly refrigerants and a small global warming effect.
3D induction log modelling with integral equation method and domain decomposition preconditioning
No full textThe deployment of electromagnetic (EM) induction tools while drilling is one
of the standard routines for assisting the geosteering decision-making process.
The conductivity distribution obtained through the inversion of the EM
induction log can provide important information about the geological structure
around the borehole. To image the 3D geological structure in the subsurface, 3D
inversion of the EM induction log is required. Because the inversion process is
mainly dependent on forward modelling, the use of fast and accurate forward
modelling is essential. In this paper, we present an improved version of the
integral equation (IE) based modelling technique for general anisotropic media
with domain decomposition preconditioning. The discretised IE after domain
decomposition equals a fixed-point equation that is solved iteratively with
either the block Gauss-Seidel or Jacobi preconditioning. Within each iteration,
the inverse of the block matrix is computed using a Krylov subspace method
instead of a direct solver. An additional reduction in computational time is
obtained by using an adaptive relative residual stopping criterion in the
iterative solver. Numerical experiments show a maximum reduction in
computational time of 35 per cent compared to solving the full-domain IE with a
conventional GMRES solver. Additionally, the reduction of memory requirement
for covering a large area of the induction tool sensitivity enables
acceleration with limited GPU memory. Hence, we conclude that the domain
decomposition method is improving the efficiency of the IE method by reducing
the computation time and memory requirement.Comment: This article is a manuscript submitted to Geophysical Journal
