Abstract

In order to support Zum-zum Island as a tourism development area in Morotai Island Regency, a well - defined planning for developing basic infrastructure is required. Foundation is a construction base of a building structure which transmits the load from the top to the layer below it. This research was conducted at Zum - Zum Beach using CPT (Cone Penetration Test). An analysis was carried out on the bearing capacity and settlement of the footing and pile foundations. The results of the analysis show that the bearing capacity of the footing foundation has a varying value depending on the width of the foundation. The greater the width of the foundation with the same type and depth, the greater the bearing capacity of the foundation permit. Meanwhile, the bearing capacity of the pile foundation permit depends on the end resistance of the foundation and diameter of the pile. The immediate settlement of the foundation on sandy soil for the largest shallow foundation is 10.24 cm with a foundation width of 0.7 m. As for the depth foundation, the magnitude of the settlement is 0.40 cm on the pile with a diameter of 0.4 m.

Abstract

CV. Eja Nursery merupakan salah satu industri pembibitan dan perkebunan karet yang terdapat di Kutai Kartanegara, tepatnya di Jalan Poros Samarinda – Bontang Km 71. Berdasarkan hasil observasi awal didapatkan bahwa terdapat beberapa postur kerja yang tidak ergonomis pada saat petani karet melakukan pekerjaannya yaitu membungkuk pada saat proses penyadapan dan proses pengangkutan getah karet. Postur kerja yang tidak ergonomis ini dapat menyebabkan petani karet mengalami keluhan musculoskeletal disorders (MSDs) yang tinggi. Berdasarkan permasalahan tersebut perlu dilakukan penelitian ergonomic assessment untuk menilai postur kerja pada aktivitas-aktivitas kerja petani karet khususnya di CV Eja Nursery, sehingga nantinya para petani dapat mengetahui tingkat risiko dari postur kerja yang dilakukannya tersebut sehingga dapat diberikan rekomendasi perbaikan sehingga risiko cedera dapat diminimalkan. Metode yang digunakan dalam penelitian ini adalah OWAS. Dari perhitungan menggunakan OWAS dapat disimpulkan bahwa, sebanyak 71% postur kerja berada pada kategori 2 yaitu postur kerja berbahaya bagi sistem muskuloskeletal dan diperlukan perbaikan di masa yang akan datang, 21% postur kerja berada pada kategori 3 yaitu postur kerja berbahaya bagi sistem muskuloskeletal dan diperlukan perbaikan segera mungkin dan 7% postur kerja berada pada kategori 1 yang berarti tidak ada masalah pada sistem muskuloskeletal. Hal ini berarti  postur kerja petani karet di CV. Eja Nursery dari tahap persiapan, pemanenan, pengangkutan hingga pemanenan masih kurang ergonomis. Perbaikan diperlukan adalah menyediakan alat bantu seperti meja dan kursi, perancangan alat bantu sadap, dan kereta dorong.

Abstract

Indonesia has many historical and cultural heritages in the form of ancient documents written in Arabic, Malay, or Jawi. There are six additional letters in Jawi, namely ca, nya, nga, pa, ga, and va to form Jawi’s vocabulary. This ancient Jawi document has suffered many quality degradations such as uneven lighting, varying contrast, blurred ink and writing, black spots, smudges, and several other glitches. Research on handwritten word recognition systems has been done extensively for Arabic scripts and various other writings. Most of the previous research focused on character level, word level, and document level. However, it still uses publicly available datasets such as IFN/ENIT, CVL dataset, IAM, and several other datasets with similar characteristics. Meanwhile, the Jawi dataset at the word level is still not available at this time. Therefore, this study examines the handwriting recognition system at the word level. The purpose of this study is to propose a new dataset (word Jawi dataset). It is hoped that this new dataset can become a more representative dataset. The process of creating a new dataset is carried out using a manual and semi�automatic approach. Furthermore, the document said Jawi will determine the Ground Truth (GT). This research produces a special dataset of words Jawi as many as 2,310 words.

Abstract

The availability of a safe food supply for the community is a right that must be fulfilled. One of the food supplies is dairy products such as milk. Milk can be processed into various types of products, including ice cream. On 8 July 2022, the European Union Rapid Alert System for Food and Feed (RASFF) reported a case of Ethylene oxide (EO) contamination in French Häagen-Dazs brand vanilla ice cream with levels exceeding quality standards (maximum of 20 mg/kg). This study aims to disseminate information about chemical contamination of ethylene oxide in ice cream and how the Indonesian authorities respond in to prevent and control the spread of contamination. The Previous case reports on 6 July 2022, authorities in France through RappelConso, and on 7 July 2022, Food Standards Australia New Zealand (FSANZ) published public information regarding the voluntary recall of Häagen-Dazs vanilla flavor ice cream by the manufacturer because it contains EO. Meanwhile, on 8 July 2022, the Singapore Food Agency (SFA) ordered importers to recall the product. In 19 July 2022, The Indonesian government through the Badan Pengawas Obat dan Makanan (BPOM) has withdrawn the vanilla flavored Haagen Dazs ice cream product circulating in Indonesia. The hypothesis that can be formulated on Ethylene oxide contamination in ice cream is the use of pesticides containing EO on vanilla flowers (the raw material for making Häagen-Dazs ice cream with vanilla flavor) leaving a high residue. The Häagen-Dazs ice cream industry must implement a good HACCP system, including a sound and safe selection of raw materials

Abstract

Terbinafine hydrochloride is a synthetic allylamine drug with a broad spectrum of antifungal properties. The purpose of this study was to identify terbinafine hydrochloride in whitening cosmetic products using High Performance Liquid Chromatography (HPLC). The first stage starts with dissolving cosmetic samples (A, B, C) and blanks, diluted with 25 ml of methanol. Then the solution was vortexed for 2 and centrifuged for 10 minutes at 4000 rpm. The supernatant layer formed was filtered through a 0.45 m membrane filter. Then the filtrate obtained was tested by the HPLC method. Based on the results of the system suitability test of the sample and blank, the concentration was 16????????/ml, the average retention time was 8.934 minutes and the average area was 2163340. The standard deviation of the relative retention time was 0.3098% and the area was 0.0721%. The follow-up factor and theoretical plate obtained automatically from the HPLC tool obtained an average follow-up factor value of 0.9515 and an average theoretical plate value of 217.7531. The results of the HPLC system suitability test and the terbinafine hydrochloride blank were identical, but the retention time was different, obtained from each different sample. All cosmetic samples contained Terbinafine hydrochloride as they did not meet the requirements. Regulation of the Minister of Health of the Republic of Indonesia Number 3 of 2021.

Abstract

Lembang District is one of the sub-districts in West Bandung Regency with the largest population of dairy cattle in West Java. an increase in the population of dairy cows will cause an increase in emissions that cause global warming. Methane is one of the greenhouse gas emissions produced from dairy cattle. Methane emissions from dairy cattle are produced when cattle burp and fart. In this study, the estimation of methane emissions from enteric fermentation uses the IPCC 2019 reference guidelines using tier 1 and tier 2. The results of calculations using tier 1 show that the highest methane emission from enteric fermentation is Sukajaya Village 8.0939 Gg CO2-eq/year and the highest is Sukajaya Village 8.0939 Gg CO2-eq/year. the lowest was Pangerwangi Village at 0.7057 Gg CO2-eq/year. Then the results of calculations using tier 2 based on local emission factors and development of emission factors show that the highest emission is Sukajaya Village at 4.8231 Gg CO2-eq/year using local emission factors, and 53.9276 Gg CO2-eq/year using development factors. emission. Meanwhile, the lowest methane emission is Pagerwangi Village at 0.0408 Gg CO2-eq/year using local emission factors. However, in the low calculation using the development of emission factors, the village that produces the lowest methane emissions is Wangunharja Village with emissions of 0.0495 Gg CO2-eq/year.

Abstract

Pest attacks that result in reduced crop yields require alternative control that is able to prevent damage to agricultural land. Organic pesticides are environmentally friendly pesticides because the materials used are derived from natural ingredients, one of which is liquid smoke, namely liquid smoke made from natural ingredients containing cellulose, hemicellulose, and lignin. This study was to determine the effect of giving liquid smoke of siwalan peel waste as an organic pesticide. Liquid smoke is obtained from the combustion process with a little oxygen at a certain temperature. The content of compounds in liquid smoke was analyzed using GCMS. Pyrolysis results obtained dark brown liquid smoke, clear, has a smoke-like odor (sangit), and has a watery texture which is used as an organic pesticide on spodoptera litura with varying concentrations of 5%, 7%, 9%, 11%, and 13%. The results of the GCMS analysis found 18 components of the liquid smoke of siwalan rind waste, among the compounds that function as organic pesticides are phenol, furfuran, acetone, and palimitic acid. The results of the analysis of the mortality of spodoptera litura sequentially showed the average value of mortality in 2 repetitions, namely 5%, 10%, 15%, 20%, and 35%. The greater the concentration of liquid smoke, the higher the mortality value. However, it is less effective to kill spodoptera litura quickly, even mortality at a maximum concentration of only 35% or has not reached the death rate of 50% of test animals.
