Identification is an activity to obtain information about an organism. Predatory insects are organisms that live freely and eat or prey on insect pests on plants. This research aimed to analyze the types of predatory insects on rice plants (Oryza sativa) in the rice fields of Malinau Kota Village and their implementation in biology learning for class X secondary school. The method used in this research was descriptive-exploratory with a qualitative approach. Sampling was taken using the roaming method using a swing net and then identified using the insect determination key book. In this study, six species of predatory insects were found. such as Gerris argentatus, Ishnura prognata, Orthetum sabina Drury, Macrodiplax cora, Micraspis crocea, and Tenodera aridifolia. Implementation of research results on predatory insects was in Learning Objective Flow 10.6., identifying the level of biodiversity by presenting reports from observations in the surrounding environment and as a teaching module for the classification of living things as well

Tanaman kangkung merupakan salah satu tanaman yang dibudidayakan oleh kelompok tani Sinar Harapan Tarakan Timur. Kehadiran gulma pada tanaman budidaya menjadi salah satu faktor penyebab penurunan hasil akibat dari perebutan unsur hara. Untuk mengetahui jenis spesies gulma dan spesies gulma yang dominan sebelum pemupukan kedua dan masa panen pada tanaman kangkung (Ipomoea reptans L.) di lahan kelompok tani Sinar Harapan Tarakan Timur maka dilakukan identifikasi. Penelitian ini dilaksanakan pada bulan November hingga Desember 2021, di lahan budidaya tanaman sayuran Kelurahan Kp 6 Kecamatan Tarakan Timur. Pengambilan sampel menggunakan metode kuadrat secara acak dengan ukuran 1 x 1 m sebanyak 30 sampel. Hasil penelitian diperoleh 19 spesies gulma dari 3 golongan gulma yaitu daun lebar sebanyak 12 spesies, rerumputan sebanyak 6 spesies, dan tekian sebanyak 1 spesies sebelum pemupukan kedua dan masa panen. Gulma yang dominan tumbuh sebelum pemupukan kedua dan masa panen yaitu dari spesies Cyperus compressus dengan nilai SDR sebelum pemupukan kedua 32,07% dan masa panen 23,35%.

Udang windu di Kota Tarakan mempunyai potensi sumberdaya perikanan yang cukup besar, sehingga menjadikan kota Tarakan sebagai salah satu sentra produksi udang windu di Indonesia. Penelitian ini bertujuan untuk mengetahui kontaminasi bakteri pada udang windu (Penaeus monodon ) di Hatchery Kota Tarakan. Penelitian ini dilaksanakan pada bulan Mei – Juni 2021. di Labolatorium Balai Karantina Ikan, Pengendalian Mutu dan Keamanan Hasil Perikanan Tarakan ( BKIPM Tarakan ) dengan sampel udang windu (Peneus monodon) yang meliputi Sterilisasi alat dan bahan, Isolasi bakteri, identifikasi bakteri dan analisis data. Metode yang digunakan pada penelitian ini yaitu dengan studi observasional untuk memberikan gambaran mengenai penelitian yang dilakukan dengan mengamati kondisi – kondisi yang terjadi melalui observasi secara langsung. Hasil penelitian dengan melakukan analisis karakterisasi bakteri dengan uji biokimia pewarnaan gram negatif, katalase positif, oksidase positif, OF tanpa paraffin fermentatif, motility positif, indol negatif, ornitin positif, TSA tegak dan miring asam. Dapat disimpulkan hasil karakterisasi bakteri dan uji biokimia bahwa terdapat 16 isolat bakteri yang mengkontaminasi udang windu pada hatchery di kota Tarakan. Tiger prawns in Tarakan City have a large enough potential for fishery resources, making the city of Tarakan as one of the centers for tiger shrimp production in Indonesia. This study aims to determine the bacterial contamination of Vibrio spp. on tiger prawns (Penaeus monodon) in the Tarakan City Hatchery. This research was conducted in May – June 2021. at the Laboratory of the Fish Quarantine, Quality Control and Safety of Fishery Products Tarakan (BKIPM Tarakan) with samples of tiger shrimp (Peneus monodon) which includes sterilization of tools and materials, isolation of Vibrio bacteria, Vibrio bacteria and analysis data. The method used in this research is with observational studies to provide an overview of the research conducted by observing the conditions through direct observation. The results of the study were carried out by analyzing the characterization of bacteria with gram negative staining tests, positive catalase, positive oxidase, OF without fermentative paraffin, positive motility, negative indole, positive ornithine, upright TSA and acid skew. Can lock the results of bacterial characterization and biochemical tests that there are 16 isolates of Vibrio spp. which contaminate tiger prawns in hatcheries in the city of Tarakan.

Morpho-meristic characteristics of layur fish (Superfamili Trihiuroidea) using trawl fishing gear in marine waters is very rarely done because fatherly is known for the length and weight of fish caught using trawling. The purpose of the research was to know the morphology of species of layur fish (Superfamili Trihiuroidea) caught in trawl fisheries in marine waters, describe the size and weight distribution of laying fish, analyze and explain the long fish weight relationship. This research was conducted from December 2018 to March 2019. The method of taking data was purposive random sampling. Data analysis included fish identification, long frequency distribution, and long weight relationship. Analysis of fish identification takes reference from the 1993 FAO book, fish species identified in Juata Laut of the Kota Tarakan, Lepturacanthus savala. The result showed distribution of long and heavy frequencies shows that during the study layur fish were caught with a length range of 32.1-37.3 cm and a weight ranging from 15.9-22.7. The relationship between the length of the first week is negative allometric with a value of b = 1.947 and the second week is negative allometric with a value of b = 2.3262 while the relationship of the length of the third week is a positive allometric with a value of b = 3.1028.
