Stingless bees (Hymenoptera: Apidae) are widely distributed in tropics and subtropics areas. Now these bees are farmed by the human because they produce honey and propolis. Natural enemies can disturb the colony that affects to nest structure and productivity of these bees. This study aimed to study the common nest structure and additional nest structure of stingless bees which caused by natural enemies. This research was conducted from August to November 2015. Samples were taken from three locations, i.e, Pasuruan (East Java), Tasikmalaya (West Java), and Rangkasbitung (Banten). Descriptive analysis was used to compare the structure and composition of the nest in bamboo and additional nest structures in relation with natural enemies. Generally, the structure and composition of the nest of stingless bees in bamboo consist of nest entrance, storage pots (honey and pollen), and brood cells. We didn’t found natural enemies of stingless bees in Pasuruan and Tasikmalaya and these colonies did not create additional nest structures. In contrast, the colonies in Rangkasbitung created additional nest structures i.e. the inner entrance covered by batumen and cerumen and also build a root-like structure. Natural enemies found in the colony at Rangkasbitung were cockroaches (Blattodea: Blattidae), histerid beetles, Platysoma leconti (Coleoptera: Histeridae), nitidulid beetles, Carphophilus sp. (Coleoptera: Nitidulidae), and ants, Pheidole sp. (Hymenoptera: Formicidae).

Abstract. The aspects of diplomacy, total defense strategy, and irregular warfare are important aspects which, if combined correctly, will be effective in the strategy of winning the war, including fighting quelling uprisings that threaten the disintegration of the Unitary State of the Republic of Indonesia (Negara Kesatuan Republik Indonesia/NKRI). This paper presents a comparison of the application of the above aspects in three cases of rebellion in Indonesia, namely Darul Islam/ Tentara Islam Indonesia (DI/TII) in West Java, the Fretilin group in East Timor, and the Free Aceh Movement (Gerakan Aceh Merdeka/GAM) in Aceh. Descriptive comparisons refer to the use of library materials to describe the common thread of differences and similarities of the three movements. As a result, exposure to differences and similarities from the application of aspects of diplomacy, total defense strategy, and irregular warfare in the three cases above. Even though the time constraints and understanding of descriptive analysis may have been a limitation in this paper, the comparative presentation presented can be subject to further study, especially regarding the case of war to quell the rebellion in Indonesia. Abstrak.

Abstract. Asmara IY, Garnida D, Partasasmita R. 2020. Crowing characteristics of Pelung chickens at different age and body weight. Biodiversitas 21: 4339-4344. Crowing characteristics such as duration, frequency, and intensity are important factors to consider in determining a good Pelung. Age and body weight are among other factors being assumed to affect crowing characteristics. The study was conducted to determine the crowing characteristics of different age and body weight. A survey was carried out in Bandung, Cianjur, and Sukabumi Districts, West Java Province, Indonesia in which a total of 98 birds was selected using a purposive technique. The observed parameters were the duration, frequency, and intensity of crowing. The duration was the length of crowing measured by seconds. Frequency is several crowing in a particular time measured by times. Intensity is the magnitude of crowing measured by decibel. The crowing was recorded from 7 AM-2 PM. Data were analyzed using descriptive analysis and Mann-Whitney U Test to compare data differences between research areas. The study found that the crowing duration of Pelung roosters tends to increase in older birds, but the decrease in heavier birds. Crowing frequency increase along with age and body weight. Crowing intensity is similar in different age groups, while the intensity tends to decrease in the heavier group. The results provide evidence that age and body weight of chickens are an important aspect in Pelung contest and age should be considered as a new category in Pelung contest.

Iskandar J, Iskandar BS, Partasasmita R. 2016.The Local knowledge of the rural people on species, role, and hunting of birds: case study in Karangwangi village, Cidaun, West Java, Indonesia. Biodiversitas 17: 435-446. Based on the ecological history, in the past many villages of in Indonesia including in West Java had a high diversity of birds. Nowadays, however, the diversity of birds in some villages of West Java has tended to decrease due to many factors, namely habitat loss, the use of pesticides, and intensive illegal bird hunting. The objective of this paper is to elucidate the local knowledge of Karangwangi village, West Java on species, role, and hunting of birds. Method used in this study is the qualitative and ethnoornithological approach with descriptive analysis. Results of study show that the Karangwangi people have a very good knowledge on bird species, particularly on level species/specific. Various bird species are traditionally classified into nine local categories (folk classification), namely based on distinctive voice/vocalization, morphological characteristic, special color, distinctive behavior, time activity, special common habitat, migrant, nest characteristics, and role in the ecosystem. Based on the rural people perception, the role of birds can be divided into two categories, namely notorious and beneficial birds. The diversity of rural birds has tended decrease over time due to various factors, including illegal bird hunting for various purposes of the village people, such as keep a bird in cages and bird trading. The study suggests the perception of rural people on birds have changed caused of socio-economic and cultural changes. Nowadays the bird hunting in the rural area has tended to shift from a purely subsistence form towards a more commercial form and, thus, to conserve bird species the study on ethnoornithology considered as a very important, and socio-economic and cultural rural people aspects might be integrated to national as well as international bird conservation programs.
