“…Salah satu pengaruh nilai produktivitas primer perairan yaitu aktivitas organisme perairan dalam memasok oksigen terlarut dan menggunakan oksigen terlarut tersebut. Tingginya densitas fitoplankton yang menyebabkan fitoplankton mendominasi di perairan tersebut akan menghasilkan oksigen dari proses fotosintesis sehingga akan berpengaruh terhadap produktivitas primer perairan (Sunaryo, 2017). Hasil oksigen terlarut Waduk Jatibarang berkisar antara 6,01 mg/l -6,94 mg/l.…”

Jatibarang Reservoir is a reservoir located in Semarang City, Central Java which has various benefits for the community and the surrounding area such as a water resource, flood control, tourist attractions, and a hydroelectric power plant. The development of human activities in the Jatibarang Reservoir will affect water quality and water fertility. Therefore, it is necessary to manage water quality through monitoring the primary productivity of the Jatibarang Reservoir. This research aims to determine the primary productivity of the Jatibarang Reservoir through the dark bottle and light bottle method approaches. The research was carried out in July 2020. The research method used is descriptive non-experimental method and the determination of the sampling point using purposive sampling method. Sampling was carried out at five stations with two repetitions. Analysis of primary productivity data using dark bottle and light bottle method. The results showed that the primary productivity of Jatibarang Reservoir ranged from 249,96-1.250.04 mg C/m3/day. Based on the results of the primary productivity, the fertility of the Jatibarang Reservoir is mesotrophic-eutrophic. ABSTRAK Waduk Jatibarang merupakan waduk yang berada di Kota Semarang, Jawa Tengah yang memiliki berbagai manfaat untuk masyarakat dan daerah sekitar seperti sebagai sumber air, pengendali banjir, tempat wisata, dan Pembangkit Listrik Tenaga Air (PLTA). Berkembangnya aktivitas manusia di Waduk Jatibarang akan mempengaruhi kualitas air dan kesuburan perairan. Oleh karena itu, dibutuhkan pengelolaan kualitas air melalui monitoring produktivitas primer Waduk Jatibarang. Penelitan ini bertujuan untuk mengetahui produktivitas primer Waduk Jatibarang melalui pendekatan metode botol gelap dan botol terang. Penelitian dilaksanakan pada bulan Juli 2020. Metode penelitian yang digunakan yaitu metode deskriptif non-eksperimental dan penentuan titik pengambilan sampel menggunakan metode purposive sampling. Pengambilan sampel dilakukan di lima stasiun dengan dua kali pengulangan. Analisa data produktivitas primer menggunakan metode botol gelap dan botol terang. Hasil penelitian menunjukkan bahwa produktivitas primer Waduk Jatibarang berkisar antara 249,96-1.250,04 mg C/m3/hari. Berdasarkan hasil produktivitas primer tersebut, kesuburan Waduk Jatibarang yaitu mesotrofik-eutrofik.

“…Primary productivity is the rate of production and storage of energy received through sunlight by autotrophic organisms. The resulting net primary productivity value can later be classified into three classes including [4] Several variables influence the productivity rate of water including chlorophyll-a, light, temperature, nutrients, rainfall, turbidity, currents, and water depth. The distribution of primary productivity also differs from ecosystem to ecosystem with near-coastal areas that are closely related to the strong distribution of nutrients from land via rivers having higher values than the open sea.…”

Ecosystems carry out internal activities, one of which is by carrying out production which is the process of inputting and storing energy from sunlight as a primary energy source called primary productivity. The development of wider coastal areas is a major factor in the importance of assessing the quality of water fertility as a measure of ecosystem change. The aim of this research is to predict the value of primary productivity in Banten Bay and the Java Sea seasonally from 2005-2020 based on MODIS Fluorescence satellite image data and processed using the Vertically Generalized Production Model (VGPM). Net Primary Productivity results obtained in Banten Bay in the West Season 148.23 mgC.m−3.d−1; Transitional Season I 148.06 mgC.m−3.d−1. East Season with 154.05 mgC.m−3.d−1; Transitional Season II 170.10 mgC.m−3.d−1 while in the Java Sea in the West Season 100.05 mgC.m−3.d−1; Transitional Season I 82.20 mgC.m−3.d−1; East Season 110.84 mgC.m−3.d−1; Transitional Season II 95.97 mgC.m−3.d−1 which decreased in value from 2005 to 2020 in both regions. Water fertility in Banten Bay and the Java Sea is higher in the nearshore area than the open sea which is influenced by chlorophyll-a, PAR availability, day length, temperature, maximum carbon fixation, euphotic zone depth, and area. Trophic status in each season in Banten Bay is included in the Oligotrophic class while in the Java Sea it is included in the Oligotrophic and Mesotrophic classes. NPP has a positive correlation with the overall capture of small pelagic fish species of 0.654 (average).

Productivity is one of the materials studied in ecology courses. As a result of the interview, many students still have difficulty in understanding this material and lecturers also have difficulty designing learning that connects context with the environment. Therefore, student learning activities need to be designed with a STEM approach. The research aims to produce a learning trajectory to help students on productivity materials using STEM approaches. The method used in this research is a design research type validation study consisting of three stages: preparing for the experiment, experiment in the classroom (pilot experiment & Teaching experiment), and restrospective analysis. The research subjects were 6 students and 3 lecturers. Research instruments in the form of interview sheets for students and lecturers and using student metacognitive questionnaires. The results of this study show that through a series of activities that have been done, learning using STEM can help students understand productivity materials and become a starting point in the learning process
