Abstract

Penelitian ini bertujuan untuk menerapkan Business Intelligence (BI) dalam mengolah data gangguan jaringan massal di PT Telkom Witel Bengkulu agar terstruktur dan dapat dianalisis menggunakan Microsoft Power BI. Permasalahan utama pada penelitian ini adalah pengelolaan data gangguan jaringan yang masih dilakukan secara manual dan terpisah, sehingga data hanya berfungsi sebagai arsip administratif dan belum dimanfaatkan secara optimal untuk analisis. Kondisi ini menyebabkan sulitnya mengidentifikasi pola gangguan, penyebab utama, serta mengevaluasi efektivitas proses perbaikan secara cepat dan akurat.. Metode yang digunakan adalah deskriptif kuantitatif melalui proses Extract, Transform, Load (ETL) terhadap data sekunder periode Januari 2024 hingga Februari 2026.Hasil penelitian menunjukkan terdapat 1.054 gangguan dengan rata-rata durasi perbaikan 4,19 jam serta tingkat kepatuhan Service Level Agreement (SLA) sebesar 88% (comply) dan 12% (not comply). Hasil analisis menunjukkan bahwa gangguan didominasi oleh jenis gangguan infrastruktur kabel dengan penyebab utama berasal dari faktor eksternal, seperti force majeure dan aktivitas pihak ketiga. Pada aktivitas perbaikan, tindakan yang paling sering dilakukan adalah catu PLN up dan sambung kembali. Dashboard interaktif yang dihasilkan mampu mengidentifikasi pola gangguan dan kinerja perbaikan secara real-time, serta memberikan insight strategis bagi manajemen dalam pengambilan keputusan berbasis data. Penerapan Business Intelligence pada penelitian ini dapat meningkatkan efektivitas monitoring, evaluasi, dan pengambilan keputusan untuk mendukung peningkatan kualitas layanan jaringan.

Abstract

Air pollution has become a challenge in recent years due to the rising of atmospheric contaminants. The increase in anthropogenic activities has led to emissions, accelerating this issue and along with environmental degradation and health problems. Researchers have noted driving factors such as energy generation, industrial operations, volcanic eruptions, and wildfires. Consequently, population density drives land use, land cover (LULC) alterations, and waste generation. Nevertheless, these factors are often overlooked when considering their contribution on emissions, which we strive to emphasize in this study. We have examined the impacts of waste, LULC, and population density on sulphur dioxide SO2, carbon monoxide (CO), nitrous dioxide (NO2), and formaldehyde (CH2O) emissions in Jakarta and its auxiliary regions in Indonesia. We gathered data from the Sentinel-2, Sentinel-5, and Copernicus, as well as waste datasets, from 2019 through 2023. Then, we analysed them via the Google Earth Engine (GEE), Excel, ArcGIS 10.8, and Minitab. Our findings indicated that population density, coupled with waste and LULC changes correlated with elevated emissions, except for SO2, which showed no such relation. This study brings out the persuasive necessity for feasible waste disposal, urban greening, reforestation, and family planning to mitigate air quality deterioration and its adverse consequences.

Abstract

Abstrak :Penelitian ini bertujuan untuk mengetahui kamislot pengaruh campuran bahan terhadap char yang dihasilkan, energi aktivasi dan karakteristik pembakarannya (ITVM, ITFC, PT dan BT). Proses pirolisis menggunakan 6 sampel uji yaitu benda uji 1 (100% bambu), benda uji 2 (100% daun pisang), benda uji 3 (100% plastik kemasan), benda uji 4 (50% bambu-50% daun pisang), benda uji 5 ( 50% bambu-50% plastik kemasan) dan benda uji 6 (50% daun pisang-50% plastik kemasan) dengan massa 20 gram. Sampel dipirolisis dengan temperatur akhir 400 oC dengan heating rate 10oC/menit. Temperatur dipertahankan selama 30 menit setelah temperatur sampel mencapai temperatur akhir yang diinginkan. Setelah char hasil pirolisis diperoleh kemudian dilakukan pembriketan sebelum pembakaran. Bahan briket memiliki massa 3 gram, yang terdiri dari 2,4 gram arang (80%) dan 0,6 gram binder (2,86% kanji dan 17,14 % air).Untuk bahan tunggal benda uji 2 ( daun pisang) menghasilkan massa akhir pirolisis tertinggi yaitu 32,8% dengan nilai kalor 3.982 kal/gram.Variasi campuran bahan berpengaruh terhadap massa char yang dihasilkan. Campuran bahan uji 4 (bambu-daun pisang) menghasilkan massa akhir pirolisis tertinggi yaitu 30,3% dengan nilai kalor 5.547 kal/ gram. Nilai kalor tertinggi dihasilkan pada campuran benda uji 6 (daun pisang–plastik kemasan) yaitu 8.360 kal/ gram yang kemungkinan disebabkan oleh uap tar yang terkandung dalam volatile matter akan menjadi reaktif. Uap tar dapat mengalami reaksi sekunder berupa cracking menjadi gas-gas hidrokarbon yang terperangkap di dalam pori-pori partikel arang atau mengalami repolimerisasi menjadi arang. Untuk bahan campuran, benda uji 4 (bambu-daun pisang) memiliki energi aktivasi terendah yaitu 22,923 (kJ/mol).Karakteristik pembakaran pada benda uji 4yaitu ITVM =158oC , ITFC=176 oC, PT =376 oC dan BT =729 oC.Kata kunci : pirolisis, char, thermogravimetry

Abstract

The social forestry program aims to provide access to community-based forest management. One of the social forestry schemes is the Village Forest. Fakfak Regency has 15 village forests that have received management licenses since 2018. However, there are various management obstacles. This research was conducted to analyze the sustainability status of 15 village forests in Fakfak Regency, to formulate appropriate management strategies. This study employed RapPForest analysis with the MDS (Multidimensional Scaling) method to evaluate the sustainability status of three dimensions and 22 attributes. Based on the analysis results, the ecological dimension has a very sustainable value (73.14), the economic dimension has a moderately sustainable status (50.01), and the social dimension is on a less sustainable index (45.79). In the ecological dimension, there are five village forests with a highly sustainable status; in the economic dimension, there are six village forests with a fairly sustainable status; in the social dimension, there are three village forests with a fairly sustainable status. The conclusion of this research is to develop recommendations for village forest management strategies that focus on achieving goals from the ecological, economic, and social dimensions.

Abstract

Cassava (Manihot esculenta Crantz), also known as tapioca or cassava, is one of the main tuber crops cultivated in humid tropical regions. In addition to being a staple food source, cassava is also used to produce tapioca flour and cassava chips through a shredding process. Cassava shredding can be done manually with traditional tools or made easier by using technology in the form of a shredding machine. However, the use of shredding machines still faces obstacles such as relatively long time and uneven shredded results. This machine is designed to increase the quantity and quality of shredded results. Horizontal knives and spring-shaped pushers are used in the machine. The way this machine works is by rotating the blade using a 125 watt electric motor, using 2 blades and machine dimensions of 60 cm long x 30 cm wide x 40 cm high. The results of this study were carried out 3 times, obtaining an average yield of 886 grams and an average time of 80.41 seconds with a production capacity of 40.636 kg / hour and a production efficiency of 88.6%.

Abstract

One of the factors influencing the performance of the can-pressing machine is the motor speed. This study aimed to determine the effect of machine rotational speed variations on the final height of compressed aluminum cans and the pressing time required. The experiments were conducted using a can-pressing machine powered by a 1 HP electric motor with rotational speed variations of 1200 rpm, 1300 rpm, and 1400 rpm. Each rotational speed was tested in three trials using 10 used aluminum cans as test specimens. The observed parameters were the final height of the cans after pressing and the time required for the pressing process. The results showed that the machine rotational speed significantly affected both the compression height and the pressing time. At 1200 rpm, the average final can height was 18.87 mm with an average pressing time of 36.67 seconds. At 1300 rpm, the average final can height decreased to 17.47 mm with an average pressing time of 20.67 seconds. Meanwhile, at 1400 rpm, the average final can height was 17.02 mm with an average pressing time of 16.67 seconds. These findings indicate that increasing the machine rotational speed results in a lower final can height and a shorter pressing time. Compared with the manual pressing method, which produced a final can height of approximately 30 mm and required about 70 seconds, the machine-assisted pressing process proved to be more effective and efficient. Based on the results of this study, it can be concluded that a rotational speed of 1400 rpm is the optimal operating condition, as it produced the smallest final can height and the shortest pressing time. Therefore, increasing the machine rotational speed within the tested range can improve the quality of the compression results and enhance the efficiency of the used aluminum can pressing process.
