Abstract

One of the challenges in construction activities is occupational safety. Every work process often involves the use of heavy equipment, heavy and dangerous building materials, and the height of the building structure, which can increase the risk of work accidents. The number of work accidents in the last five years shows a reasonably high increase, with 32% of work accidents in Indonesia coming from the construction sector. This study aims to identify potential hazards and risks of work accidents, conduct risk assessments, and provide control efforts for the dangers in the Al-Bakrie Grand Mosque construction project in Bandar Lampung. The method used is HIRADC (Hazard Identification, Risk Assessment, and Determining Control). The hazard identification is based on literature studies, field observations, and interviews. Risk assessments are carried out to determine how high the risk is by filling out questionnaires by respondents, namely the frequency level questionnaire and the severity level questionnaire. The questionnaire was then processed using the severity index method and risk matrix sourced from PUPR Regulation No. 10 of 2021. The results of the analysis show that 35 hazard variables have the potential to cause work accidents. The risk assessment results obtained a low-risk category of 31 (88%) and a medium-risk category of 4 (12%). Control efforts must be carried out to eliminate or even reduce the risk of work accidents in the project by the control hierarchy, namely elimination, substitution, technical control, administrative control, and personal protective equipment (PPE).

Abstract

Penggunaan varietas unggul merupakan salah satu strategi untuk meningkatkan produktivitas tanaman bawang merah. Varietas merupakan salah satu faktor kunci yang mempengaruhi pertumbuhan bawang merah. Suatu varietas dikatakan adaptif terhadap kondisi lingkungannya apabila pertumbuhan dan produktivitasnya tidak menunjukkan perbedaan yang nyata dibandingkan dengan kinerjanya di daerah penanaman asalnya. Penelitian ini bertujuan untuk mengevaluasi potensi hasil beberapa varietas bawang merah di Kabupaten Sleman. Penelitian dilaksanakan pada bulan April sampai dengan Juli 2024 di Kecamatan Kalasa, Kabupaten Sleman, Daerah Istimewa Yogyakarta. Metode yang digunakan adalah Rancangan Acak Kelompok Lengkap (RAL) dengan enam perlakuan varietas (V): V1 = Katumi, V2 = Kuning, V3 = Pikatan, V4 = Gempita Agrihorti, V5 = Kramat 1, dan enam kali ulangan, sehingga diperoleh total 30 satuan percobaan. Hasil penelitian menunjukkan bahwa varietas Gempita Agrihorti (V4) menunjukkan parameter pertumbuhan tinggi tanaman tertinggi pada umur 1-2 minggu setelah tanam (MST). Sementara itu, varietas Katumi (V1) secara konsisten menunjukkan kinerja terbaik pada beberapa parameter, meliputi bobot daun segar per rumpun, bobot biomassa segar per rumpun, bobot biomassa kering per rumpun, dan total padatan terlarut. Penelitian lebih lanjut diperlukan untuk mengeksplorasi penggunaan varietas adaptif lain dan jenis pupuk yang cocok untuk budidaya di dataran rendah, seperti di Kabupaten Sleman.

Abstract

The morphological similarity of bulb characteristics among shallot varieties can determine the genetic relatedness between them, which is valuable for selecting potential parent varieties in plant breeding programs. This study utilized eight qualitative and three quantitative bulb morphological characteristics to analyze the relatedness of eleven elite shallot varieties in Indonesia. The aim of this research was to determine the genetic relatedness of eleven shallot varieties (Kuning, Gempita, Pikatan, Kramat-1, Pancasona, Katumi, Bima Brebes, Trisula, Violetta 1, Maja Cipanas, and Ambassador 2) based on the identification of eleven morphological bulb characteristics using the UPOV (2008. Relatedness analysis was conducted using cluster analysis with OriginPro 2022 software to determine similarity values that aid in data grouping. The results showed that at 0 - 25% morphological similarity, there were two main clusters; at 50% morphological similarity, there were seven sub-clusters; and at 75% morphological similarity, there were eleven clusters, each consisting of a single variety. Among the eleven shallot varieties, some exhibited high similarity values ranging from 61% to 71%, such as Gempita Agrihorti and Ambassador 2 Agrihorti, Violetta 1 Agrihorti, and Kramat 1. This high similarity may be due to the use of the same parent varieties, Maja Cipanas and Trisula, in the breeding process. Kata kunci: bawang merah, kekerabatan, karakter morfologi umbi.
