Setiawati T, Susilawati A, Mutaqin AZ, Nurzaman M, Annisa, Partasasmita R, Karyono. 2018. Morpho-anatomy and physiology of red galangal (Alpinia purpurata) and white galangal (Alpinia galanga) under some salinity stress levels. Biodiversitas 19: 809-815. Soil salinity is one of the most urgent issues in agriculture as it can reduce plant growth and productivity. Efforts on development of galangal plant on saline soils are still encountering some obstacles such as lack of information on the galangal types that are tolerant to saline condition. The purpose of this study was to determine morpho-anatomical and physiological responses of red galangal (Alpinia purpurata (Vieill.) K. Schum.) and white galangal (Alpinia galanga (L.) Willd.) to salinity stress treatments. This research used a Randomized Block Design (RBD) assigned in a factorial treatment design of two factors, i.e., (i) species of galangal consisting of two levels i.e., red galangal and white galangal, (ii) NaCl concentration consisting of five levels, i.e., 0‰, 3‰, 6‰, 9‰ and 12‰. Each treatment was three replicates. Observation was done on the growth parameters when the plants showed wilting symptoms. The observed data were subjected to Analysis of Variance (ANOVA), followed by a post hoc Duncan Multiple Range Test (DMRT) at ? 5% when the treatment effect was significant. The results showed that salinity stress treatment significantly reduced the plant height increase, leaf area, dry weight, stomata density, chlorophyll content and increased thickness of root epidermis, and proline content in both species of galangal. Red galangal was more tolerant than white galangal.

Manik H, Yurmiaty H, Asmara IY, Handarto, Iskandar J, Partasasmita R. 2018. Wattled Brushturkey hunting system in the Sigim and Sinaitousi communities in the buffer zone of the Arfak Mountain Nature Reserve, West Papua, Indonesia. Biodiversitas 19: 849-856. Illegal hunting is still the cause of the decline of wildlife populations in nature. This is particularly the case with protected wildlife and endemic species, such as the Wattled Brushturkey in Palau West Papuan. Thus, research needs to be done on the hunting system at the site. The aim of this research was to know Wattled Brushturkey (Aepypodius arfakianus) hunting system by Sigim and Sinaitousi villagers, Arfak Mountains of West Papua. The research used descriptive method with field observation technique and semi-structured interviews. The results showed that the main purpose of hunting Wattled Brushturkey conducted by the Sigim and Sinaitousi communities is to consume the meat, while a part of egg hunting is for sale. The hunting by the two villagers was generally done in groups. The frequency of hunting depends on needs and demand. Hunting is done using snares, dogs, and combinations of snares and dogs. The tools used are snares, machetes, air rifles, arrows nad bows. The modern tools such as gun have been used in both villages. The hunting of Wattled Brushturkey begins in the morning and continues until late afternoon. The location of hunting is usually primary forest, secondary forest of former garden and river basin.

Abstract

Choir IR, Iskandar J, Parikesit, Partasasmita R, Husodo T, Kumoro J, Megantara EN. 2018. The local management and sustainability of swidden farming in the Villages of Bojongsalam and Sukaresmi, Upper Cisokan Watershed, West Java, Indonesia. Biodiversitas 19: 1054-1065. In the past, the swidden farming (huma or ladang) system had been predominantly practiced by village people of West Java. Nowadays, however, the huma farming has rarely been practiced by the village people of West Java due to the government policy, and environmental and socioeconomic changes. The local community who reside in the Villages of Bojongsalam and Sukaresmi, the upper stream of Cisokan, West Java, Indonesia, has still practiced both the wet rice field (sawah) and the huma farming in the private land, production forest of a state-owned forest company (Perhutani), and a state-owned electric company (PLN) project land. Recently some areas of the huma land have been used for the project of the Hydroelectric Power Plant of the Upper Cisokan Pumped Storage (UCPS). As a result, the sustainability of huma system of the local people of Bojongsalam and Sukaresmi has been seriously disturbed. The aims of this study were to elucidate the local management of the huma farming systems that are undertaken by local people of Bojongsalam and Sukaresmi Villages, and to analyze the sustainability of the huma farming of local people of Bojongsalam and Sukaresmi Villages as affected by the UCPS Hydroelectric Power Plant project. The qualitative method was used, while several techniques of collecting the primary data, namely observation and in-depth interviews with informants were applied in this study. The results of study showed that the local management of the huma farming has been annually undertaken by the local people of Bojongsalam and Sukaresmi, including deciding the location of huma plot, preparing the land (cutting shrubs and burning vegetation biomass), planting rice (ngaseuk) and other annual crops, weeding (ngored) and providing chemical fertilizers (mupuk), controlling pests, harvesting rice (dibuat), and fallowing land. Based on analysis of the emergent properties of the agroecosystem of huma farming, it can be predicted that productivity, stability, equitability, and sustainability of the huma farming systems of Bojongsalam and Sukaresmi Villages tend to be low in the near future due to the impact of UCPS Hydroelectric Power Plant project.
