Riparian merupakan vegetasi yang tumbuh di tepi perairan dan berpotensi sebagai habitat dan sumber makanan bagi ekosistem perairan. Penelitian ini bertujuan untuk mengetahui struktur vegetasi riparian dan pengaruhnya terhadap keanekaragaman makrozoobentos di Situ Gintung. Titik pengambilan sampel terdiri dari 8 stasiun dengan 3 kali pengulangan. Analisis hubungan vegetasi riparian dengan makrozoobentos diuji dengan regresi linier sederhana dan korelasi Pearson. Hasil penelitian menunjukkan bahwa vegetasi riparian yang terdapat pada 8 stasiun terdiri dari 2 kelas (Magnoliopsida dan Liliopsida), 11 spesies dengan nilai indeks keanekaragaman (H') sebesar 1,517. Makrozoobentos yang ditemukan terdiri dari 2 kelas (Gastropoda dan Crustacea) 7 spesies dengan nilai indeks keanekaragaman (H') sebesar 1,112. Hasil analisis regresi menunjukkan adanya korelasi antara vegetasi riparian dengan kepadatan makrozoobentos yang tergolong sempurna (0,972). Hal ini menunjukkan bahwa vegetasi riparian di Situ Gintung berkorelasi positif dengan keanekaragaman makrozoobentos.AbstractSitu Gintung is an aquatic ecosystem that is very important in water conservation in the Campus 2 Area of UIN Syarif Hidayatullah Jakarta. Riparian is vegetation that grows at the edge of water and has the potential to serve as habitat and food source for aquatic ecosystems. This research aims to determine the structure of riparian vegetation and its influence on macrozoobenthos diversity in Situ Gintung. The sampling point consists of 8 stations with 3 repetitions. Analysis of the relationship between riparian vegetation and macrozoobenthos was tested using simple linear regression and Pearson correlation. The research results showed that the riparian vegetation was found at 8 stations consisting of 2 classes (Magnoliopsida and Liliopsida), 11 species with a diversity index (H') value of 1.517. The macrozoobenthos found consisted of 2 classes (Gastropoda and Crustacea) 7 species with a diversity index (H') value of 1.112. The results of the regression analysis showed that there was a correlation between riparian vegetation and macrozoobenthos density which was classified as perfect (0.972). This shows that riparian vegetation in Situ Gintung is positively correlated with macrozoobenthos.","PeriodicalId":505278,"journal":{"name":"Al-Kauniyah: Jurnal Biologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139174365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Penelitian ini bertujuan untuk menganalisis respon pertumbuhan dan produksi tanaman kale terhadap penambahan POC pada sistem hidroponik Deep Flow Technique (DFT). Penelitian menggunakan Rancangan Acak Kelompok dengan 5 perlakuan, yaitu dosis POC (0; 10; 20; 30; dan 40 mL/L). POC disemprotkan ke daun setiap minggu sejak hari ke-0 sampai 35 hari setelah tanaman.

Penambahan POC berpengaruh nyata pada pertumbuhan tanaman kale (P <0,05), yaitu POC konsentrasi 10 mL/L dapat meningkatkan panjang akar tanaman (41,25 cm) dan berpengaruh tidak nyata terhadap parameter lainnya seperti tinggi tanaman, jumlah daun, diameter batang, berat basah, dan kering tanaman serta berat layak konsumsi. Namun, tanaman kale yang disemprot POC memiliki nilai rata-rata semua parameter lebih tinggi dari kontrol (0 mL/L).

Kale can be cultivated hydroponically using AB mix as fertilizer, but the nutrients often settle at the bottom of the tub and are difficult for the roots to absorb. The addition of Liquid Organic Fertilizer (POC) which is sprayed through the leaves is expected to provide additional nutrition for plants. This research aims to analyze the growth and production response of kale plants to the addition of POC in the Deep Flow Technique (DFT) hydroponic system. The study used a randomized block design with 5 treatments, namely POC doses (0; 10; 20; 30; and 40 mL/L). POC is sprayed on the leaves every week from day 0 to 35 days after planting. Data analysis used analysis of variance (ANOVA) and further DMRT test at the 5% level. The addition of POC has a significant effect on the growth of kale plants (P <0.05), namely POC concentration of 10 mL/L can increase plant root length (41.25 cm) and has no significant effect on other parameters such as plant height, number of leaves, stem diameter. , wet and dry weight of the plant and weight suitable for consumption. However, kale plants sprayed with POC had an average value of all parameters higher than the control (0 mL/L).

Upaya konservasi Lutung Jawa antara lain dengan sistem ex-situ di Kebun Binatang Gembira Loka, Yogyakarta. Pemberian jenis pakan yang disesuaikan dengan pakan alami Lutung Jawa menjadi salah satu upaya untuk mencapai kesejahteraan hewan konservasi. Oleh karena itu, penelitian ini dilakukan untuk mengamati komposisi pakan populasi Lutung Jawa di Kebun Binatang Gembira Loka dengan total waktu 480 jam melalui metode scan sampling. Komposisi pakan Lutung Jawa yang diberikan oleh Kebun Binatang Gembira Loka terdiri adalah daun (7%), buah dan sayur (92%), dan suplemen (4%), Jenis pakan yang paling banyak dikonsumsi oleh Lutung Jawa di Kebun Binatang Gembira Loka adalah buah dan sayur.

The choice of food type for animals is very dependent on the availability of food in their habitat and morphological adaptations, especially the animal's digestive organs. Trachypithecus auratus is a primate endemic to the islands of Java, Bali and Lombok which is listed as vulnerable by IUCN (vulnerable) and CITES (Appendix II). Javanese langur conservation efforts include an ex-situ system at the Gembira Loka Zoo, Yogyakarta. Providing types of feed that are compatible with the natural diet of Javan langurs is one of the efforts to achieve the welfare of conservation animals. Therefore, this research was conducted to observe the food composition of the Javan langur population at Gembira Loka Zoo for a total of 480 hours using the scan sampling method. The composition of the Javanese langur feed provided by the Gembira Loka Zoo consists of leaves (7%), fruit and vegetables (92%), and supplements (4%), where fruit and vegetable feed has the highest percentage of consumption by each individual. Apart from that, the group of food consumed was compared with wild populations from the results of research that has been carried out, where Javan langurs at the Gembira Loka Zoo consume more fruit and vegetables. This shows that the eating behavior of Javan langurs at Gembira Loka Zoo is different from their natural eating behavior, namely leaf eating (folivor), so it is necessary to adjust the food composition of Javan langurs at Gembira Loka Zoo, Yogyakarta.","PeriodicalId":505278,"journal":{"name":"Al-Kauniyah: Jurnal Biologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139175607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
