Abstract

Salah satu unit pengelolaan Perusahaan Hutan Negara Indonesia (Perhutani) yang mengembangkan hutan jati adalah Kesatuan Pemangku Hutan (KPH) Banyumas Timur. Hutan jati yang dikelola KPH Banyumas Timur terdiri dari berbagai kelompok umur. Umur tegakan berkaitan dengan tutupan tajuk dari pohon di sekitar tumbuhan bawah yang berpengaruh terhadap keanekaragaman tumbuhan bawahnya. Penelitian ini bertujuan untuk menganalisis vegetasi keanekaragaman dan kemerataan jenis tumbuhan bawah pada berbagai umur tegakan Jati (Tectona grandis L.) di KPH Banyumas Timur. Penelitian dilakukan di Hutan jati BKPH Kebasen, KPH Banyumas Timur, dengan tiga kelompok umur tegakan yaitu 16, 20 dan 22 tahun. Hasil penelitian menunjukkan bahwa pada berbagai umur tegakan jati di KPH Banyumas Timur terdapat 34 jenis tumbuhan bawah dari 17 familia. Tegakan jati umur 16 tahun memiliki keragaman tumbuhan tertinggi dengan indek nilai penting tertinggi sebesar 42,77% pada Echinochloa colona (L.) dari familia Poaceae. Keanekaragaman tumbuhan bawah pada tegakan jati dengan umur 16 tahun sebesar 2,12 dengan kemerataan jenis sebesar 0,73. Nilai kesamaan jenis tertinggi sebesar 30,77% dari tegakan jati berumur 20 tahun sedangkan tegakan jati berumur 16 tahun dengan 20 tahun sebesar 25% dan 26,67%. Komposisi dan distribusi serta tinggi rendahnya keanekaragaman tumbuhan bawah pada ketiga tegakan jati umur berbeda, dapat dipengaruhi oleh faktor lingkungan yang terbentuk disekitar tegakan.

Abstract

Pacific Seabream, Acanthopagrus pacificus, is a popular marine fish from the Sparidae family. This species is an economically essential fisheries commodity in the south-coast Java, Indonesia. However, limited studies are available on A. pacificus in Indonesia. Only two studies reported the presence of A. pacificus in South-Coast Java. No study has been carried out on the biology of A. pacificus from south-coast Java. Therefore, biological studies of A. pacificus are needed, including genetic diversity studies. This study aimed to evaluate the genetic diversity of A. pacificus in South-Coast Java using the cytochrome c oxidase gene. Fish samples were bought from Bantul Fishing Harbor, Yogyakarta, Panganadaran Fishing Port, Bojongsalawe Fish Auction Center, West Java, and Binuangeun Fishing Harbor in Lebak Regency, Banten. The genetic marker was processed in PT. Genetika Science Indonesia follows the company procedure. Haplotype and nucleotide diversity were calculated mathematically using Arlequin software. The result showed that polymorphic loci were only 1.3%, indicating low polymorphisms. A. pacificus showed haplotype and nucleotide diversities of 0.511±0.110 and 0.15%±0.12%, respectively. Those values indicated low genetic diversity. This study concluded that the A. pacificus population in South-Coast Java showed low genetic diversity. This study provides the first data about the genetic diversity of A. pacificus in South-Coast Java, which is essential data for fisheries management.

Abstract

Groundwater utilization in Narmada Regency has increased significantly while its availability is decreasing. This requires management to maintain clean water supply. Research on variables that affect groundwater availability and interactions between them therefore needs to be carried out. Firstly, a Focused Group Discussion (FGD) was held to identify the variables considered important in groundwater management. Respondents then filled out a set of questionnaires expressing their perceptions about the importance of these variables. The variables were grouped into four dimensions namely Input, Output, Domestic Output and non-Domestic Output. Next, respondents' responses were analyzed using the MICMAC structural analysis tool to sort out variables regarding their influence and dependence as well as evaluating the interactions that occured between the variables.  The results showed that there are 7 key variables i.e. Central Government Regulations (PPP). Local Government Regulations (PPD), Rainfall (HUJ), Groundwater Basin (CAT), Forest (HUT), Climate (IK), Number of Population (JP) and 1 regulatory variable ie. Geological variable (GEO) in the groundwater availability system in Narmada District. Also, there exist structured and systematic interactions between dimensions in the system. The results of this study are useful as input in making appropriate regulations for sustainable groundwater in the study area.

Abstract

Catastrophic mortality occurred in the fish community at Serayu Movable Dam in 2022. The phenomenon was caused by severe water quality alteration due to sediment flushing from Panglima Besar Soedirman Dam. After the incident, the fish community in the reservoir has never been evaluated. This study aimed to assess the fish community status in the Serayu Movable Dam post-catastrophic mortality in 2022. The study was conducted using a survey method, and fish samples were collected three times at six sampling sites at an interval of two weeks. Fish identification was done using the identification key in the references. Various community and water quality parameters were measured. The data obtained were analyzed descriptively by comparing them with standards in the literature. A total of 27 species were identified with a richness index of 4.564, relative abundance of 0.037, diversity index of 2.111, evenness index of 0.693, and dominance index of 0.259. The data proved that the fish community in Serayu Movable Dam has recovered after two years of catastrophic mortality in 2022. It could be due to the characteristic of the riverine ecosystem that can revert due to the continuous replacement of water from various tributaries that flow into the Serayu River in the upstream part of the Serayu Movable Dam, as shown by good water quality. It can be concluded that high ichthyofauna diversity was observed in the Serayu Moveable Dam post-catastrophic mortality. The data are essential scientific bases for sediment flushing management at P.B. Soedirman Dam and management of freshwater fish community in Serayu Movable Dam.
