Macroinvertebrates are one of the bioindicators in aquatic ecosystems. The diversity and distribution patterns of functional groups of macroinvertebrate communities are assessed to determine water quality. The objective of this research was to figure out the abundance and distribution of macroinvertebrates in Watu Lumbung Beach, Gunungkidul, Yogyakarta. This study was conducted in May 2022 with the quadrat transect method using 1×1 m quadrats along Watu Lumbung Beach, Gunungkidul, Yogyakarta. Sampling was conducted at two randomly determined stations from the lowest low tide to the middle of the sea. The first station is located near Watu Lumbung reef, which has a distance of 50 m, while the second station is 250 m from the reef, so the distance between stations is 200 m. The Shannon-Weiner diversity index (H') was calculated by analyzing the data. The data obtained in this study are the results of the inventory of macroinvertebrate species at each sampling point and the number of individuals of each species. The results showed the abundance of macroinvertebrates on Watu Lumbung beach found as many as 16 species belonging to 13 families and classified into nine classes (Polychaeta, Malacostraca, Anthozoa, Echinoidea, Ophiuridae, Gastropoda, Polyplacophora, Pilidiophora and Demospongia). The family Ophiocomidae (Ophiocoma erinaceus and Ophiocoma scolopendrina) were the most abundant species at both observation stations. The diversity index is 1.94, which shows that the diversity of macroinvertebrates on Watu Lumbung Beach is categorized as moderate.

Achatina fulica termasuk ke dalam kategori hama di bidang pertanian dan perkebunan yang dapat diambil manfaatnya sebagai bahan pangan, pakan, dan obat. Dibutuhkan pemahaman terhadap perilaku untuk dapat melakukan penanganan terhadap bekicot sebagai hama tanaman. Penelitian ini bertujuan untuk mengetahui perilaku harian bekicot (A. fulica) dan dilakukan di Kebun Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Yogyakarta, Yogyakarta, Indonesia. Terpilih empat individu bekicot yang ditemukan di area kebun biologi untuk diamati perilaku hariannya. Pengamatan dilaksanakan dengan menggunakan tiga metode yaitu ad libitum, focal sampling, dan behaviour sampling. Data dianalisis secara deskriptif terkait aktivitas harian bekicot di lapangan baik secara keseluruhan maupun secara individu. Berdasarkan hasil pengamatan, didapatkan bahwa aktivitas utama yang dilakukan bekicot pada pukul 08.23 hingga 15.23 WIB adalah diam atau istirahat yang menunjukkan persentase 68,91%. Hal tersebut disebabkan karena meningkatnya intensitas cahaya sehingga aktivitas A. fulica berkurang. Aktivitas lainnya ialah investigate yang menunjukkan hasil persentase sebanyak 20,73%, lokomosi yang memiliki hasil persentase sejumlah 10,08%, dan mengeluarkan kotoran dengan persentase 0,28%. Penelitian ini memberikan manfaat untuk pengembangan strategi pengendalian populasi dan teknik budidaya bekicot secara efektif. serta menjadi landasan untuk penelitian lanjutan. Achatina fulica belongs to the category of pests in agriculture and plantations that can be utilized as food, feed, and medicine. It takes an understanding of behavior to be able to handle snails as plant pests. This study aimed to determine the daily behavior of snails (A. fulica) and was conducted at the Biology Garden, Faculty of Mathematics and Natural Sciences, Yogyakarta State University, Yogyakarta, Indonesia. Four individual snails found in the biology garden area were selected to observe their daily behavior. Observations were carried out using three methods, namely ad libitum, focal sampling, and behavior sampling. Data were analyzed descriptively related to the daily activities of snails in the field both as a whole and individually. Based on the results of observations, it was found that the main activity carried out by snails at 08.23 to 15.23 WIB was silence or rest, which showed a percentage of 68.91%. This is due to the increasing light intensity, which decreases the activity of A. fulica. Other activities are investigation, which shows a percentage of 20.73%; locomotion, which has a percentage of 10.08%; and excreting, with a percentage of 0.28%. This research provides benefits for the development of population control strategies and effective snail cultivation techniques, as well as a foundation for further research.

Fruit flies are important pests of citrus crops. Identifying fruit fly species is very important to make the appropriate conclusions in determining controlling methods. This study was intended to establish the dominant species, diversity index, and identification of fruit fly species in Siam citrus (Citrus nobilis Lour.) orchards in Dau District, Malang Regency, Indonesia. This study was conducted in two habitat types: close and far from residential areas. Six petrogenol-treated traps were placed at each location from December 2022 to February 2023, and every two weeks, the fruit flies caught in the traps were counted as part of the survey. The results showed that three species, namely B. dorsalis, B. carambolae, and B. umbrosa, were found in locations close to residential areas, while B. umbrosa was not found in locations far from residential areas. The dominant species was B. dorsalis in both locations. The diversity index of Bactrocera spp. in orchards close to residential areas was 1.14 (moderate), and Spearman's analysis (0.913) showed a more substantial influence than in orchards far from residential areas. Climatic factors of air humidity, air pressure, and host availability play an essential role in the presence of fruit flies.

The hydroponic technique is a solution for agricultural activities that do not require a large area of land because it does not require soil as a growing medium but uses water. Rockwool is a commonly used seedling medium in hydroponics. Organic waste has the potential to be used as seedling media because it contains many substances and microorganisms that are beneficial for plant growth. This study aimed to determine the effectiveness of banana fronds, sugarcane stalks, and orange peel waste as seedling media for lettuce (Lactuca sativa L.) plants that are environmentally friendly in hydroponics. This study used a Non-Factorial Completely Randomized Design (CRD) with five treatments and four replications, where each replication consisted of 20 samples. The results of DMRT analysis showed that various compositions and types of seedling media had different effects on each characteristic, namely seedling height, number of leaf blades, germination percentage, water absorption, and the level of consistency of the mash. Banana fronds, sugarcane stalks, and orange peel waste in the ratio of 1:2:1 have the potential to be an environmentally friendly seedling media for hydroponic lettuce cultivation.
