Abstract

Kaligarang River Semarang City is one of the rivers with various activities around it. The purpose of this study was to analyze the quality of the waters of the Kaligarang River and the diversity of fish species as bio-indicators in the Kaligarang River, Semarang City. The method of this research was exploration by taking samples at five stations using a fishing net and fishing line. Fish obtained were identified species and counted the number of each species. Kaligarang waters quality is done by testing the parameters of temperature, pH, COD, current speed, and substrate base. The data obtained were analyzed by Margalef Wealth Index (Dmg), Shannon-Wiener diversity (H '), evenness index (E) and Simpson dominance index (C). Water quality measurements are carried out together when sampling. The results showed that there were five species of fish caught namely Oreochromis niloticus (nila), Cichlasoma labiatus (red devil), Barbodes schwanenfeldii (bader), Rasbora agryrataenia (wader), Pterygolichthys pardalis (sapu-sapu). The diversity index of fish species in the Semarang City Kaligarang River is below 3.5 (H '<3.5) and there is a predominant species, Oreochromis niloticus (nila) throughout the observation station. Water quality is within safe limits for temperature and pH parameters, while dissolved oxygen and COD parameters still below the limit Sungai Kaligarang Kota Semarang merupakan salah satu sungai dengan beragam aktivitas di sekitarnya. Tujuan penelitian adalah menganalisis kualitas perairan Sungai Kaligarang dan keanekaragaman spesies ikan sebagai bioindikator di Sungai Kaligarang Kota Semarang. Metode dalam penelitian ini adalah eksplorasi dengan pengambilan sampel di lima stasiun menggunakan jala tebar dan alat pancing. Ikan yang diperoleh diidentifikasi jenis serta dihitung jumlah individunya. Kualitas perairan Kaligarang dilakukan dengan pengujian parameter suhu, pH, COD, kecepatan arus, dan substrat dasar. Data yang diperoleh dianalisis dengan indeks Kekayaan Jenis Margalef (Dmg), keanekaragaman Shannon-Wiener (H’), indeks kemerataan (E) dan indeks dominansi Simpson (C). Pengukuran kualitas perairan dilakukan bersama saat pengambilan sampel. Hasil penelitian menunjukkan ikan yang tertangkap ada lima spesies yaitu Oreochromis niloticus (nila), Cichlasoma labiatus (red devil), Barbodes schwanenfeldii (bader), Rasbora agryrataenia (wader), Pterygolichthys pardalis (sapu-sapu).

Abstract

Wreathed Hornbill (Rhyticeros undulates) is known to build nests in three cavities where they managed to live and breed. This edifice is predicted to contain various molds needed to maintain micro-environmental steadiness. This study was aimed to identify molds diversity in the Wreathed Hornbill’s nest, using samples collected from empty structure with no bird activity. The samples were obtained from the Kalisidi and Nglimut observation stations on two occasions, i.e., in 2016 and 2017. Furthermore, the samples comprised cover soil, wood and inner material, which were collected aseptically and placed in sterile Ziplock plastic bags. These samples were then diluted in sterilized distilled water to attain 10-3 mg/ mL, and subsequently inoculated on Potato Dextrose Agar (PDA), Malt Extract Agar (MEA) and Czapek Dox Agar (CDA). The inoculants were incubated at 37 °C, followed by the observation of mold colony after the 11th day. The results identified seven and nine species of molds in the Kalisidi and Nglimut observation stations, respectively. The most abundant species was Penicillium sp. which was found in composted nest materials for the whole observation periods.

Abstract

Abstract Gempol Village is a village on Mount Ungaran that has made efforts to preserve orchid species. Through mentoring and training from the UNNES Research Team which began in 2011, as well as greenhouse facilitation from PT Indonesia Power, the Gempol village community who are members of the Omah Sawah Community began to make efforts to conserve orchid species. The results of the identification of the problems experienced by community groups as foster partners can be grouped into three aspects, namely knowledge and skills of acclimatization of orchids from plant tissue culture, post-acclimatization management/care, and supporting infrastructure for acclimatization of tissue cultured orchids, where these three aspects are interrelated. The methods used include lecture and question and answer activities, practice, and mentoring. The result achieved is that the orchid species acclimatization activity in Gempol Hamlet, Ngesrepbalong Village has been carried out with satisfactory results. Activities are carried out through training and assistance to community groups who are members of Omah Sawah. The results of the evaluation of the participants showed that the participants' understanding and skills improved after this activity was carried out, even providing ideas for participants to apply to cultivated orchids. The result is enough to generate economic income for the participants, because some of their cultivated orchids are sold. Abstrak Dusun Gempol adalah satu dusun di Gunung Ungaran yang telah melakukan upaya pelestarian anggrek species hutan . Melalui pendampingan dan pelatihan dari Tim Peneliti UNNES yang dimulai pada tahun 201, serta fasilitasi greenhouse dari PT Indonesia Power, masyarakat Dusun Gempol yang tergabung dalam Komunitas Omah Sawah mulai melakukan upaya pelestarian anggrek species. Hasil identifikasi terhadap permasalahan yang dialami kelompok masyarakat sebagai mitra binaan dapat dikelompokkan menjadi tiga aspek, yaitu pengetahuan dan keterampilan aklimatisasi anggrek hasil kultur jaringan tanaman, pengelolaan/ perawatan pasca aklimatisasi, dan sarana prasarana penunjang aklimatisasi anggrek hasil kutur jaringan, dimana ke tiga aspek ini salingterkait. Metode yang dilakukan, meliputi kegiatan ceramah dan tanya jawab, praktik, dan pendampingan. Hasil yang dicapai adalah kegiatan aklimatisasi anggrek species di Dusun Gempol Desa Ngesrepbalong telah dilaksanakan dengan hasil yang memuaskan. Kegiatan dilaksanakan melalui pelatihan dan pendampingan terhadap kelompok masyarakat yang tergabung di Omah Sawah.
