Abstract

Air pollution kills about seven million people worldwide every year. In Indonesia itself, especially the city of Jakarta, Jakarta's air quality has been ranked as the tenth worst in the world. The purpose of the research is to design an air pollution monitoring system that can help the community to know the level of pollution in their area. The system development method uses a system development life cycle, namely the waterfall. The evaluation method uses blackbox testing for the system and eight golden rules for the user interface. The result achieved is a system that can monitor IoT-based air pollution with the cloud. This system uses several technologies such as Google cloud platform which consists of IoT Core, Pub Sub, Firestore Database, and Google Cloud Function. The MQ 135 temperature sensor and ESP 32 module are also used to be able to read air pollution conditions and send it to the cloud. The conclusion of this study is that the system created can be easily accessed by users to be able to determine IoT-based air quality.

Abstract

Selada merupakan sayuran yang banyak dikonsumsi di Indonesia. Salah satu cara membudidayakan selada adalah menggunakan hidroponik dengan sistem rakit apung dan pemanfaatan teknologi lebih lanjut untuk mendapatkan hasil yang lebih baik adalah menggunakan paparan medan elektromagnetik. Tujuan dari penelitian ini adalah untuk mendapatkan hasil terbaik dari variasi paparan medan elektromagnetik pada pertumbuhan selada berupa jumlah daun, panjang akar, berat segar, dan berat kering. Penelitian ini menggunakan perangkat solenoida sebagai sumber medan elektromagnetik. Perlakuan pada penelitian ini disajikan sebanyak tiga, yaitu T0 (merupakan variabel tanpa perlakuan medan elektromagnetik), T1 mempunyai medan elektromagnetik 0,00027 Tesla, dan (T2) mempunyai medan elektromagnetik 0,00047 Tesla. Rancangan penelitian yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap dengan 3 perlakuan dan 5 kali ulangan. Data yang diperoleh dianalisis dengan menggunakan ANOVA dan Uji BNT 5%. Perlakuan dengan menggunakan paparan medan elektromagnetik pada pertumbuhan salada dapat berpengaruh nyata pada variabel pengamatan. Hasil yang signifikan didapatkan oleh variabel (T2) yang mendapatkan hasil rata-rata jumlah daun sebanyak 11,7 helai, rata-rata panjang akar sepanjang 35,8 cm, jumlah total berat segar seberat 114,53 gram, dan jumlah total berat kering seberat 12,56 gram. ABSTRACT Lettuce is vegetable that is widely consumed in Indonesia. One way to cultivate lettuce is using hydroponics with floating raft system and further technology utilisation to get better results is using electromagnetic field. The purpose of this study is to get best results from variations in electromagnetic field on lettuce growth in the form of number of leaves, root length, fresh weight, and dry weight. This research uses solenoid as a source of electromagnetic field. The treatments in this study are presented as three, namely (T0) without electromagnetic field, (T1) has an electromagnetic field 0.00027 Tesla, and (T2) has an electromagnetic field 0.00047 Tesla. The research design used in this study was completely randomised design with 3 treatments and 5 replications. The data obtained were analysed using ANOVA and LSD 5% test. Treatment using electromagnetic field on lettuce growth can significantly affect the observation variables. Significant results were obtained by the (T2) which obtained average number of leaves of 11.7 strands, average root length of 35.8 cm, total fresh weight of 114.53 grams, and the total dry weight of 12.56 grams.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh green accounting, carbon emissions disclosure, profitabilitas, dan Environmental Social Governance (ESG) disclosure terhadap nilai perusahaan. Data penelitian yang digunakan adalah data sekunder berupa laporan tahunan dan laporan keberlanjutan perusahaan sektor basic materials yang terdaftar di Bursa Efek Indonesia periode 2021-2024. Metode pengambilan sampel yang digunakan adalah metode purposive sampling. Banyaknya sampel yang digunakan adalah 16 perusahaan. Metode analisis yang digunakan adalah analisis regresi data panel. Hasil penelitian ini menunjukkan bahwa green accounting, profitabilitas, dan ESG disclosure tidak berpengaruh terhadap nilai perusahan, sedangkan carbon emissions disclosure berpengaruh negatif terhadap nilai perusahaan.   This study aims to examine the effect of green accounting, carbon emissions disclosure, profitabilitas, and Environmental Social Governance (ESG) disclosure on firm value. The research data consist of secondary data obtained from the annual reports and sustainability reports of basic materials sector companies listed on the Indonesia Stock Exchange for the period 2021–2024. The purposive sampling method was used to select the sample, resulting in a total of 16 companies. The analysis was conducted using panel data regression. The results indicate that green accounting, profitabilitas, and ESG disclosure have no significant effect on firm value, whereas carbon emissions disclosure has a negative impact on firm value.
