Get PDFABSTRAK Memanfaatkan air yang higiene sanitasi mutlak diperlukan agar terhindar dari dampak negatif yang tidak diinginkan. Penelitian ini dilaksanakan dengan mengambil empat titik sampel (stasiun) air sumur gali di Kampung Yamta Arso Kabupaten Keerom Papua pada bulan Agustus sampai Oktober 2022. Penelitian ini bertujuan untuk mengetahui status mutu air dengan metode indeks pencemaran. Parameter pencemaran air yakni: parameter fisika (kekeruhan, warna, TDS dan suhu, rasa dan bau), parameter kimia (pH, besi, flourida, kesadahan, mangan, nitrat, nitrit, sianida, detergen dan pestisida total) serta parameter biologi (coliform total dan Escherichia coli). Hasil penelitian menunjukkan bahwa status mutu air sumur gali pada stasiun 2 dan 3 diperoleh indeks pencemaran berturut-turut sebesar 2,00 dan 2,67 tergolong tercemar ringan, sedangkan pada stasiun 1 dan 4 diperoleh indeks pencemaran berturut-turut sebesar 0,65 dan 0,69 termasuk kategori baik (memenuhi baku mutu). Parameter yang tidak memenuhi baku mutu air adalah kekeruhan, pH, besi, detergen dan Escherichia coli. Hal ini dikarenakan melebihi baku mutu. Rancangan pengendalian air yang cocok agar memenuhi persyaratan baku mutu perlu dilakukan filtrasi dengan media zeolite, pasir, ijuk dan karbon aktif (karang tempurung kelapa) dan menambahkan sedikit klorin (kaporit) dan atau tawas pada bak penampung sebelum filtrasi. Kata kunci: Mutu, Air, indeks, Sumur, Yamta.  ABSTRACT Utilizing water that is hygienic and sanitary is absolutely necessary to avoid unwanted negative impacts. This research was carried out by taking four sample points (stations) of dug well water in Yamta Village, Arso District, Keerom Regency, Papua from August to October 2022. The aim of this research was to determine the status of water quality using the pollution index method. The Water pollution parameters were: physical parameters (turbidity, color, TDS and temperature, taste and smell), chemical parameters (pH, iron, fluoride, hardness, manganese, nitrate, nitrite, cyanide, detergent and total pesticides) and biological parameters (coliform total and Escherichia coli). The results of the research showed that the water quality status of dug wells at stations 2 and 3 obtained a pollution index of 2.00 and 2.67, respectively, which was classified as lightly polluted, while at stations 1 and 4, pollution indices were obtained, respectively, of 0.65 and 0.69 was included in the good category (met the quality standards). Parameters that did not meet water quality standard were turbidity, pH, iron, detergent and Escherichia coli. This is because it exceeded the quality standards.  A suitable water control design to meet quality standard requirements requires filtration using zeolite, sand, palm fiber, and activated carbon (coconut shell coral) media and adding a little chlorine (chlorine) and/or alum to the holding tank before filtration. Keywords: Quality, Water, Index, Well, Yamt

Air Quality Monitoring in Briquette Industrial Environments through Air Particle Detection Systems
Get PDFAir is the most basic need for the survival of living things, especially humans. Briquetting plants are one of the industries that produce airborne particles harmful to human health and the surrounding environment. These particles can cause respiratory problems and serious illnesses if not properly detected and controlled. Therefore, an air particle detection system is indispensable for monitoring air quality in the factory environment. PT Arkelindo Bara Sejahtera, as a company engaged in the manufacture of briquettes, has a negative impact on the environment, especially air pollution due to the carbonization process that produces smoke and dust. The implementation of this community service activity aims to improve air quality in the briquette industry environment through the implementation of an air particle detection system. This activity includes socialization about the dangers of air particles, training on the use of detection devices, and filling out questionnaires to evaluate participants' understanding. The results of this activity show that the air quality in the factory environment is still poor with high Air Quality Index (AQI) values, mainly caused by the carbonization process. However, this activity succeeded in raising the awareness of the factory staff on the importance of air quality monitoring and providing concrete recommendations to reduce particle emissions, including the use of cleaner fuels and improving the efficiency of the carbonization process.

PREDICTION OF HIGHER HEATING VALUE OF VARIOUS BIOMASSES USING THE EQUATION FOR THE HYDROTHERMAL CARBONIZATION METHOD ON BANANA BUNCHES
Get PDFWhen designing many variables influence the thermal conversion system for homogeneous biomass and heterogeneous biomass. The factor that can have an important influence is the higher the calorific value (HHV). Many correlation models have been developed to estimate the HHV of homogeneous and heterogeneous biomass to reduce analysis costs. Unfortunately, the correlation model for predicting biomass HHV still has shortcomings when predicting biomass data from different thermal conversion processes and different types of biomass. In this study, four new correlations based on proximate and ultimate analysis of homogeneous biomass with the hydrothermal carbonization (HTC) method used for HHV prediction are presented. The multiple linear regression method is used to produce correlations from homogeneous biomass data then compare biomass models from open literature and compare correlation accuracy for data from the literature. It was found that the correlation obtained from proximate analysis (HHV =967.171 -8.684Ash -9.299VM -9.913FC) was more accurate than that obtained from proximate

Optimasi Uji Tegangan Tarik Pengelasan Tungsten Inert Gas pada Penggabungan Beda Material Baja Galvanish (SGCC) dengan Baja Karbon Rendah (SPCC-SD)
Get PDFPengelasan adalah salah satu proses utama dalam industri manufaktur yang digunakan untuk menggabungkan dua atau lebih material logam. Salah satu metode pengelasan yang umum digunakan adalah Tungsten Inert Gas (TIG) welding. TIG welding merupakan teknik pengelasan dimana terjadi pembentukan busur listrik antara elektroda yang tidak meleleh dengan material kerja. Pengelasan TIG antara baja galvanis (SGCC) dan baja karbon rendah (SPCC-SD) sering digunakan pada industri otomotif karena kedua material tersebut memiliki karakteristik yang berbeda sehingga bisa digunakan pada kondisi operasional yang berbeda. Penelitian ini menggunakan metode Taguchi dengan tiga tingkat percobaan dan tiga faktor yang berbeda, yaitu Arus listrik, Laju aliran gas argon, dan diameter kampuh las. Hasil penelitian menunjukan bahwa flowrate adalah parameter yang paling penting karena memiliki perbedaan nilai S/N ratio yang paling besar. Hal ini menunjukan flowrate memiliki nilai yang signifikan lebih tinggi daripada arus dan diameter kampuh las sehingga berperan penting dalam menentukan kualitas kekuatan sambungan pengelasan TIG pada material SGCC dan SPCC-SD terhadap tegangan tariknya. Hasil analisis rasio S/N menunjukkan bahwa parameter yang paling optimal adalah arus listrik 55 A, laju aliran gas 18 lpm, dan diameter las 5 mm. Sementara itu, analisis ANOVA menunjukkan bahwa laju aliran gas memiliki kontribusi paling signifikan dalam mempengaruhi beban tarik pada pengelasan TIG bahan SPCC-SD (JIS 3141) dengan SGCC (JIS 3302) yaitu sebesar 23,24%. Selanjutnya disusul oleh diameter kampuh las dan arus pengelasan masing-masing memberikan kontribusi sebesar 19,82% dan 8,34%

Dengan menggunakan 1031 data, didapatkan sentimen positif (bukan buzzer) sebesar 63.69%, sentimen negatif (buzzer politik) sebesar 31.94%, dan sentimen netral sebesar 4.37%. Sehingga disimpulkan bahwa model lexicon-based mampu menjelaskan sentimen X.Kata Kunci: Analisis sentimen, Lexicon-based, Buzzer, X, PemiluABSTRACTElection is a moment where people have a role to participate in the government. Social media, especially X social media, is one of the most popular ways to disseminate information. Information that is spread in large quantities is very difficult for the public to filter properly. Influencing public opinion by using harsh words, manipulating information, and creating negative content is the role of political buzzers in social media. So a tool is needed to filter public sentiment that is circulating. The tool used is sentiment analysis. The research aims to classify the sentiment of political buzzers in social media X using a lexicon-based model that is enhanced by the dictionary according to the case study conducted (corpus-based). By using 1031 data, positive sentiment (not buzzer) is 63.69%, negative sentiment (political buzzer) is 31.94%, and neutral sentiment is 4.37%. So it is concluded that the lexicon-based model is able to explain X sentiment.Keywords: Sentimen analyzed, Lexicon-based, Buzzer, X , Electio
