Abstract

Morphometric and Meristic research on the types of fish of the order Perciformes in the Banyuasin River Estuary, Banyuasin Regency, South Sumatra Province, was carried out in March-April 2021. Sampling was carried out using the purposive sampling method by following fishermen exploring water areas where there were estimated to be a lot of fish. The fishing gear used is nets, fishing rods, fishing rods and traps. The fish obtained were photographed and preserved in a coolbox with 10% formalin. Fish were identified and classified in the Biology laboratory of PGRI Palembang University. The types of fish of the order Perciformes obtained consisted of Familia Latidae species Lates calcarifer, family Scatophagidae species Scatophagus argus, family Serranidae species Epinephelus coiodes, familia Polynemidae species Eleutheronema tetradactylum.Keywords: Perciformes, Morphometric, Meristic, Banyuasin River Estuary.

Abstract

Penelitian uji mortalitas kumbang beras (Sitophilus oryzae) dengan pengendalian hayati jamur Beauveria basianna. Tujuan penelitian untuk menganalisis kemampuan mortalitas S. oryzae terhadap B. basianna yang dilakukan pada bulan Maret  hingga Mei 2021 di Laboratorium Mikrobiologi dan Bioteknologi Fakultas Sains dan Teknologi universitas PGRI Palembang.  Penelitian menggunakan RAL yaitu pemberian B. basianna dengan konsentrasi yang berbeda-beda yang terdiri dari 5 perlakuan dan 4 ulangan yaitu P0 (kontrol), P1 ( konidia cfu/ml), P2 ( konidia cfu/ml), P3 ( konidia cfu/ml), P4 ( konidia cfu/ml), P5 ( konidia cfu/ml). Hasil penelitian menunjukkan adanya pengaruh konsentrasi perlakuan terhadap mortalitas S.oryzae. Perlakuan P5 ( konidia cfu/ml) menghasilkan persentase mortalitas tertinggi dengan rata-rata sebesar 28,75%.

Abstract

Research on the Order of Diptera on Melon Plant (Cucumis melo L.) was conducted in April - May 2022.”The purpose of the study was to examine the interest of insects in melon plants to various colors in the agrotorism of the Kenten Laut melon garden. This study uses a purposive sampling method, namely by color traps using 4 colors, namely, yellow, green,blue, and red. Observation parameters include the number of insects contained in each trap, color and type of head, mouth apparatus, limbs, antennae, and wings. The results obtained 70 insects fromthe order Diptera. The types of insects found were, Bactrocera dorsalis., Lucilia sp.,”Hermetia illucens, Musca domestica., the insects collected had different morphological types.

Abstract

Research on the morphology of insects attracted to color traps was carried out in April-June 2023, aiming to study the interest of insects to color and their morphology in red chili plantations, Pedu Village, Jejawi Sub-district, OKI District. This study used a survey method. Sampling by purposive sampling. The color traps used are red, yellow, green and blue. The observation parameter is the number of trapped insect species. Many insects are housed both in the number of species and in the number of individuals of each species. The results of the study found 11 insect species namely, Bactrocera dorsalis, Epilachna sp, Periplanetta americana, Bemisia tabaci, Nezara viridula, Valanga nigriconis, Odontomachus sp., Musca domestica, Agelastica alni, Oxya chinensis, Polistes sp. scattered in red 8 species, yellow 8 species, green 8 species, and blue 1 species. Mouth morphology types include chewing, sucking, piercing-sucking, biting-sucking, and biting-chewing. Head morphology types include hypognathus, prognathus, and opistrorincus types. Antenna morphology types include filiform, clavate, pectinate, aristale, and geniculate types. Wing morphology types include membrane, elytra, halter, and tegmina types. The morphological types of insect violations include cursorial, saltatorial, raptatorial, and natatorial types. 81% of pests, 9% of saprophagus and 9% of pollinators get the role of insects.

Abstract

ABSTRACT Research on the growth patterns and eating habits of bearded fish (Esomus metallicus) in the Ogan River was carried out in April-May 2024. This research aims to study the growth patterns of bearded fish and analyze the types of food of bearded fish that live in the Ogan River, Palembang City. The research uses a survey method. Sampling was carried out at 3 stations. Station I is around water vegetation or is a natural habitat for fish, station II is around residential areas and station III is around a rubber factory. The fish obtained were taken as samples from 5 individuals each from each station. Each fish was measured for total length and weight. The sample was then dissected, the stomach was taken. The contents of the stomach are examined to see the composition of the types of food, and measure the total volume of food eaten and the volume of each type of food to determine the largest type of food (Index of Preponderance). The research results showed that the composition of the jangut fish's food was phytoplankton (44.39%), leaf debris (27.26%), zooplankton (0.26%) and unidentified (28.07%). The growth pattern of beard fish is negative allometric or growth in length is faster than growth in weight. Keywords: Esomus metallicus, Index of Preponderance, allometric

Abstract

Research on the morphological structure of porang plants growing in Sribunga Village, Buay Pemuka Bangsa Raja District, East Oku Regency was carried out in This research was carried out from March to June 2024. The porang plants (Amorphophallus muelleri) studied were taken from community plantations in Sribunga Village, Buay District Leaders of the Raja Nation of East Oku Regency. Examination of morphological characteristics was carried out at the Biology Laboratory, Faculty of Science and Technology, PGRI University, Palembang. The research uses a survey method. Data analysis includes the basic structure of plants, namely roots, leaves, stems and plant modifications. The morphology of the porang plant (Amorpophallus muellery) has a fibrous root system (radix adventitia). The stem (caulis) has a false stem which is modified into a root tuber. The leaves (folium) are finger-shaped compound leaves. The flowers (flos) are compound cob flowers (spadix) with large reddish bracts (spatha).

Abstract

Research of Analysis of Weeds in Rice Plantations (Oryza sativa) was conducted in April - June 2025, located in Wanasari Village, Semendawai Timur District, East OKU Regency. The purpose of the study was to analyze weed vegetation in rice plantations (Oryza sativa). This study uses survey methods. Sampling using on the plot which is carried out based on a rectangular plot measuring 2 m x 2 m with a total of 5 plots is placed systematically. The results of the study found 9 species from 7 genera and 7 families. The nine species are Scoparia dulcis, Ophiopogon japonicus, Ludwigia peploides, Ludwugia octovalvis, Ageratum conyzoides, Fimbristilys littoralis, Cyperus kyllingia, Cynodon dactylon, and Sida rhombifolia. The highest weed density calculation was in the Cynodon dactylon species with a value of 7.8 ind/m2 and the lowest in the Scoporia dulcius species with a value of 2.65 ind/m2. The highest important value index (INP) was Cynodon dactylon with an important value index value of 25.73%. While the lowest important value index was the Scoparia dulcis weed type with an important value index of 16.08%. Diversity index is included in the moderate category with a value of  2,13.
