Abstract

Human activities that produce carbon dioxide emissions and are called carbon footprints or carbon footprints have a big role in global warming. As part of its contribution to climate change mitigation efforts and environmental preservation, Faculty of Mathematics and Natural Science Universitas Negeri Semarang (FMIPA UNNES) has been actively developing conservation policies. The programs developed as an effort to mitigate climate change have been running for a long time. However, so far it is not certain how much CO2 emissions are produced and minimized by FMIPA UNNES. The purpose of this study was to analyze the amount of CO2 emissions produced in the FMIPA environment, to map the carbon footprint (CO2) produced from activities on the Unnes campus, to identify what factors influence CO2 emissions resulting from activities in FMIPA. The research was conducted from May to October 2020. The data obtained were obtained from primary data and secondary data. Primary data were obtained through field surveys, while secondary data were obtained from existing data. The carbon footprint that will be taken is obtained from electronic measurements, waste and transportation. The data instrument was converted into carbon footprint units (grams CO2-ek) using a carbon footprint calculator (Ver 2) developed by IESR. The results showed that the carbon footprint generated from campus activities at FMIPA in 2020 before the Covid-19 pandemic outbreak was 10,670.25 ton CO2-eq / month. This carbon footprint decreased during the pandemic to 4,312.27 ton CO2-eq / month. This total carbon footprint consists of scope one in the form of transportation activities by operational vehicles and use of LPG, scope two of electricity spending activities, scope three in the form of transportation activities by lecturers, staff, and students, use of paper, and waste disposal.

Abstract

This experiment was conducted to study the effect of probiotic bacteria SKT-b Vibrio addition at different developmental stages on survival rates of tiger shrimp Penaeus monodon larva.  Main activity of this experiment consisted of tiger shrimp rearing started from nauplius stage until Pl10 and addition of 106 CFU/ml SKT-b Vibrio probiotic bacteria at various developmental stages namely at early nauplius stage, early zoea zoea stage, early mysis stage, early postlarva (Pl) stage, every developmental stage changes, everyday, and control (without probiotic bacteria addition). Results showed that survival rates of shrimp larva ranged at 24,17%-35,83% with the higest value in the treatment of probiotic bacteria addition at every developmental stage changes namely 35,83%, whereas the lowest was found at control (without probiotic bacteria addition) namely 24,17%.  No significantly different was found in term of shrimp growth rate among control and treatment. Growth rate in length of tiger shrimp larva ranged 18,64%-19,09% for SKT-b Vibrio addition and 18,47% for control. Key word: Probiotic bacteria, SKT-b Vibrio, Penaeus monodon, shrimp larvae stages   ABSTRAK Penelitian ini dilakukan untuk mempelajari pengaruh pemberian bakteri probiotik Vibrio SKT-b pada stadia yang berbeda terhadap kelangsungan hidup larva udang windu Penaeus monodon. Kegiatan utama dari penelitian ini adalah pemeliharaan udang windu yang dimulai dari stadia nauplius sampai Pl10 dan diberi bakteri probiotik Vibrio SKT-b dengan dosis 106 CFU/ml pada waktu yang berbeda yaitu pada awal stadia nauplius, awal stadia zoea, awal stadia mysis, awal stadia postlarva (Pl), setiap pergantian stadia, setiap hari, dan kontrol (tanpa pemberian bakteri probiotik). Hasil penelitian yang diperoleh menunjukkan bahwa tingkat kelangsungan hidup larva udang berkisar antara 24,17%-35,83% dengan nilai tertinggi terdapat pada perlakuan pemberian bakteri probiotik pada setiap pergantian stadia yaitu sebesar 35,83%, sedangkan terendah pada perlakuan kontrol (tanpa pemberian bakteri probiotik) yaitu 24,17%.  Sedangkan terhadap pertumbuhan tidak terdapat perbedaan yang signifikan antara kontrol dengan perlakuan. Nilai laju pertumbuhan panjang larva udang windu dengan penambahan bakteri probiotik Vibrio SKT-b berkisar antara 18,64%-19,09% dan kontrol sebesar 18,47%. Kata kunci: Probiotik, Vibrio SKT-b, Penaeus monodon, stadia larva udang
