The purpose of this qualitative descriptive study was to find out the types of pathogenic fungi that caused rotten cacao fruits based on morphological characteristics in Tumba village. Fungi isolation was performed by employing the moist chamber method with the PDA medium. Moreover, the identification of pathogenic fungal isolates followed the morphological characteristics mentioned earlier. The results showed that four fungal isolates contributed to the rotting of cacao fruits in the site area. Fungal isolate Tumba 1 (T1) had morphological characteristics of a white colony with smooth surface, and oval sporangium with a bulge on its tip; fungal isolate Tumba 2 (T2) consisted of morphological characteristics of a white colony with a pink circle in the middle, and having a sickle-shaped and oval macroconidia; fungal isolate Tumba 3 (T3) comprised morphological characteristics of a dark black colony with irregular shape, uneven edge, and having a long conidiophore with a big conidial head; fungal isolate Tumba 4 (T4) had morphological characteristics of a black colony with a white circle in the middle, uneven edge, and having a tube-shaped conidium. As based on the morphological characteristics, it was assumed that the four fungal isolates causing the rotten cacao fruit were similar to the types of fungi, i.e., Phytopthora palmivora, Fusarium sp, Aspergilus niger, and Gloeosprorium sp.

Flies are the most commonly used insects in forensic entomology, namely as an indicator for determining the duration of death or PMI (Post Mortem Interval). The flies that usually come first and colonize carcasses are the Muscidae, Sarcophagidae, and Calliphoridae families. The purpose of this study was to determine the species of flies found in the carcass of Syrian Hamster (Mesocricetus auratus Waterhause) with different euthanasia outdoors, and to see which types of flies were abundant and not abundant in each treatment. The research was conducted in Bedoyo Village, Ponjong, Gunung Kidul, Yogyakarta Special Region, from September to March. The sample consisted of 9 male Syrian Hamsters (M. auratus) divided into 3 groups of euthanasia, namely dislocation by pulling the body and neck, burning on firewood for 30 seconds, and poisoning with 2.5 ml of liquid mosquito repellent. The hamster carcass was then placed on the ground covering an area of 504 m2 with a distance between the carcasses of 2.5 m. The collection of fly larvae is carried out every 2 days for 6 days or until the carcass is decomposed. Data analysis was performed using descriptive analysis to describe the types of flies found in hamster carcasses and inferential to calculate the correlation between abiotic factors and the abundance of fly larvae in the three treatments. The fly species found were Chrysomya megachepala in euthanasia dislocation 1 larvae and Sarcophaga haemorrhoidalis in euthanasia dislocation 14, poisoned 16 and burned 25 larvae. The presence and abundance of C. megacephala and S. haemorrhoidalis in carcasses did not correlate with the measured abiotics. The conclusion of this study is the type of treatment can affect the type and abundance of flies found on the carcass.
苍蝇是法医昆虫学中最常用的昆虫，即作为确定死亡持续时间或PMI(验尸间隔)的指标。通常最先到达并定居在尸体上的苍蝇是蝇科、麻蝇科和蝇科。本研究的目的是确定不同室外安乐死处理的叙利亚仓鼠(Mesocricetus auratus Waterhause)尸体中蝇类的种类，并观察每种处理下哪些蝇类数量较多，哪些蝇类数量较少。该研究于9月至3月在日惹特别行政区的Ponjong, Gunung Kidul的Bedoyo村进行。以9只雄性叙利亚仓鼠(M. auratus)为研究对象，将其分为3组安乐死，分别为拔身拔颈脱臼、柴火灼烧30秒、驱蚊液2.5 ml中毒。然后将仓鼠尸体放置在504 m2的地面上，尸体之间的距离为2.5 m。每2天采集蝇幼虫一次，持续6天或直至胴体腐烂。采用描述性分析方法描述仓鼠尸体中蝇类的种类，采用推理分析方法计算三种处理中非生物因素与蝇类幼虫丰度的相关性。在安乐死错位1号幼虫中发现巨型金蝇，在安乐死错位14号幼虫中发现痔疮石蛉，中毒16只，烧伤25只。巨头锥虫和痔疮锥虫在尸体中的存在和丰度与测量的非生物制剂无关。本研究的结论是处理方式会影响尸体上蝇类的种类和丰度。

Entomopathogen is one of the biological agents that infects the insects and can damage the body's metabolic system of insects. This objective of the study were to determine the entomopathogenic activity of S. marcescens on mortality of coconut leaf beetles larvae (B. longissima), and the time needed to reach LT50. The study used an experimental method with 6 treatments of varying S.marcescens volumes, consisting of A (distilled water as a control), B (5 ml), C (7.5 ml), D (10 ml), E (12.5 ml), and F (15 ml) with 4 replications. The data were analyzed using ANOVA and Probit LT50 test. The results showed that the volume of S.marcescens had an effect on mortality of coconut leaf beetle B. longissimi larvae. The best mortality rate at treatment E is 78% with the value of LT50 in treatment F is 42.15 hours. S.marcescens has entomopathogenic activity in coconut leaf beetles (B. longissima) Gestro larvae.

The research was aimed at explaining the morphometric ratio of fiddler crab ( Uca sp.) based on the difference among the population in Tanjung Panjang Nature Preserve. The technique of data collection was exploration with quantitative descriptive approach. The data analysis test applied average test and T- test. Findings revealed that the variation of the characteristics of morphometric of the two population was different on the characteristics of major claws propondus (2,55±0,16 mm) with the highest variation was found in station II (0,75±0,09 mm). The morphometric characteristic variations which were significantly different between the two population were carapace, major claws, and mouth. The variations among the population were clearly, seen through carapace posterior width, major claws propondus, major claws dactylus major claws and mouth length.

Analysis of Mangrove Ecosystem Potential as Carbon Absorbent, For Development of Textbook Material On Ecology Course". Thesis of Graduate Program of State University of Gorontalo (UNG). The principal supervisor was. Prof. Dr. Ramli, Utina, M.Pd. and the co-supervisor was Dr. Elya Nusantari, M.Pd. This study aims To determine the quality of textbooks based on research for the development of teaching materials on the subject of ecology subject matter and energy. Development of research-based learning tools of subject matter and Energy using R & D model through 10 steps of development then simplified on three stages, namely (1) exploration stage, (2) prototype development stage, and (3) product validation stage, As for the products produced in this study is a textbook. The resulting product development is then validated by material experts, design experts, and students. The result of the research shows that (1) textbook based on research according to the material expert from the whole aspect of assessment for the validation of textbook is 93.75% including excellent quality, because it is in the range of 81% to 100%, (2) For the validation of textbook design is 91.67%, including excellent quality, because it is in the range of 81% to 100%, (3) student response to the overall quality of textbook aspect is at 94% percentage where this value belongs to very good category because it is In the range of 81 to 100%.
