<![CDATA[Goldfish (Cyprinus carpio L) is a very popular type of fish and has been widely known by people throughout Indonesia. Goldfish is one type of consumable fish that includes inland fishery commodities, namely freshwater fisheries that have good prospects. In increasing fishery production efforts, especially freshwater fisheries, what really needs to be considered is the quality of fish fry as well as their mothers. To improve the good and superior quality of fry and broodstock fish, it is necessary to carry out the process of handling fish through the method of chromosome manipulation. This study aims to determine the effect of heat shock time on the triploidization process on egg quality and survival of ika Mas larvae (Cyprinus carpio L). This research was conducted from February 7 to March 5, 2005 at the BPBAT (Freshwater Aquaculture Fish Development Center) laboratory, Marga Sakti Village, Padang Jaya District, North Bengkulu Regency. The method used in this study was an experimental method of Complete Randomized Design (RAL) with 4 treatments and 3 repeats, while the four treatments were treatment A (Heat shock) 1.5 minutes, Treatment B (Heat shock) 2 minutes, Treatment C (Heat shock) 2.5 minutes and Treatment D (Heat shock) 3 minutes. The data from the study were analyzed using Anova fingerprints and the Duncan Multiple Range Test (DMRT) follow-up test to see differences in treatment. At the time of the study after artificial fertilization in the mother carp, the sample eggs were scattered on a glass slab of 12 units according to the predetermined number of eggs then put them into the water temperature of 27O For 3 minutes, after 5 minutes from the fertilization process remove all glass plates simultaneously and give a heat shock into a temperature of 39O According to each treatment. The results showed that the length of heat shock time in the triploidation process had a very noticeable different influence (P<0.05) on the fertilization value (NF), embryo survival (NKHE), egg hatching value (NPT) and seven-day-old larvae (LU7). The best heat shock was given to the C treatment with a duration of 2.5 minutes, resulting in the highest carp egg fertilization value of 82.96%, while the embryo survival value was around 68.67%, the egg hatching value was 62.57% and the seven-day-old larva with a value of 57.33%. ABSTRAK Ikan mas (Cyprinus carpio L) adalah jenis ikan yang sangat popular dan sudah banyak dikenal oleh masyarakat diseluruh Indonesia. Ikan mas merupakan salah satu jenis ikan konsumsi yang termasuk komoditas perikanan darat yaitu perikanan air tawar yang memiliki prospek yang baik. Dalam meningkatkan usaha produksi perikanan khususnya perikanan air tawar yang sangat perlu diperhatikan adalah kualitas benih ikan begitu pula dengan induknya. Untuk memperbaiki kualitas benih dan induk ikan yang baik dan unggul perlu dilakukan proses penanganan ikan dengan melalui metode manipulasi kromosom. Penelitian ini bertujuan mengetahui pengaruh lama waktu kejutan panas (heat shock) pada proses triploidisasi terhadap kualitas telur dan kelangsungan hidup larva ika Mas (Cyprinus carpio L). Penelitian ini dilaksanakan pada tanggal 7 Februari sampai 5 Maret 2005 bertempat di laboratorium BPBAT (Balai Pengembangan Ikan Budidaya Air Tawar) Desa Marga Sakti Kecamatan Padang Jaya Kabupaten Bengkulu Utara. Metode yang digunakan dalam penelitian ini adalah metode eksperimental Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan, adapun ke empat perlakuan tersebut adalah perlakuan A (Kejutan panas) 1,5 menit, Perlakuan B (Kejutan panas) 2 menit, Perlakuan C (Kejutan panas) 2,5 menit dan Perlakuan D (Kejutan panas) 3 menit. Data hasil penelitian di analisis dengan menggunakan sidik ragam Anova dan uji lanjut Duncan Multiple Range Test (DMRT) untuk melihat perbedaan perlakuan. Pada waktu Penelitian setelah pembuahan buatan pada induk ikan mas telur sampel di tebarkan diatas lempengan kaca sebanyak 12 unit sesuai dengan jumlah telur yang sudah ditentukan kemudian masukkan kedalam suhu air 27O Selama 3 menit, setelah 5 menit dari proses pembuahan angkat seluruh lempeng kaca secara bersamaan dan lakukan pemberian kejutan panas kedalam suhu 39O Sesuai dengan masing-masing perlakuan. Hasil penelitian menunjukkan bahwa Lamanya waktu kejutan panas pada proses triploidiasi memberi pengaruh berbeda sangat nyata (P<0,05) terhadap nilai fertilisasi (NF), kelangsungan hidup embrio (NKHE), Nilai penetasan telur (NPT) dan larva umur tujuh hari (LU7). Pemberian kejutan panas terbaik pada perlakuan C dengan lama waktu 2,5 menit, sehingga menghasilkan nilai fertilisasi telur ikan mas tertinggi 82.96 %, sedangkan nilai kelangsungan hidup embrio berkisar 68,67%, nilai penetasan telur 62,57% dan Larva umur tujuh hari dengan nilai 57,33%.]]>

<![CDATA[Empat Lawang Regency is one of the regencies in South Sumatra which is known for its pretty good geotourism potential. The location of Empat Lawang Regency which is in the South Sumatra basin, with the influence of tectonic control and sedimentation which tends to be diverse and dominant, makes the research location contain forms and landscapes with a variety of beauty and uniqueness, one of which is karst and waterfalls. Thus, research conducted with the aim of knowing the potential of geotourism in depth is very interesting to do. In more detail, this research was carried out in several stages, namely primary and secondary data collection, processing based on Kubalíková's (2013) quantitative value consisting of intrinsic and scientific value, educational value, economic value, conservation value, and additional value, stages of studio work , to the last stage in the form of report preparation. Based on the results of observations that have been made, there are 8 locations that have the potential as geosite areas. However, after an analysis of Kubalíková's (2013) assessment, it turned out that only 5 sites contained an assessment percentage of more than 50% or could be said to be priority sites for development into geotourism areas. These priority sites are contained in a geotrack map consisting of 2 travel destination lines. Geotrack 1 contains the Sanghe Waterfall Puyang Berang Sane Statue - Serunting Sakti River. Meanwhile, the Geotrack 2 route contains the Black Pool and Mekarjaya Cave.]]>

<![CDATA[This study aims to see how much influence inflation, trade, and farmer exchange rates have on economic growth in Lampung Province. The method used is a descriptive-analytical method with a quantitative approach with multiple regression analysis tests. The data used is secondary data from the Central Statistics Agency (BPS) from 2018-2021. The results of the study showed that simultaneously there was no significant influence between inflation, trade, and farmer exchange rates on economic growth. The three indicators of economic growth that have a significant effect are inflation, the higher the inflation, the lower the economic growth, while the lower the inflation, the more positive the economic growth will be. Partial testing, inflation does not have a positive effect on economic growth, but hurts economic growth, meaning that decreasing inflation will have a positive impact on economic growth and conversely increasing inflation will not have a positive effect on economic growth. . Trade does not have a positive impact on economic growth, meaning that increasing trade will not have a positive effect on economic growth. The Farmer's Exchange Rate does not have a positive effect on Economic Growth, meaning that the greater the Farmer's Exchange Rate, it will not have a positive effect on Economic Growth.]]>

<![CDATA[Orangutans (Pongo spp.) are currently found only on the islands of Sumatra and Borneo. Bornean orangutan (Pongo pygmaeus) face a high risk of extinction due to almost 80% of the distribution of orangutans in Kalimantan occurs outside of conservation areas. Orangutans are also found in the Coal Mining Rehabilitation Area called ARPB in Sangatta, East Kutai, East Kalimantan. The objective of this research was to estimate the orangutan population living in ARPB in Sangatta. Data collection used direct observation to orangutan found in ARPB. This study has found 41 orangutans in ten ARPBs covering an area of 912.29 ha, from November 2013 to January 2015. The orangutans found consists of 17.07% of adult males, 39.02% of adult females, 12.20% of juveniles, 9.76% of children, and 21.95% of infants. This was an indication of the success of orangutans’ adaptation in the coal mining area, especially in ARPB. The fact about population and demographic structure of orangutans in ARPB leads to indications of the success of orangutans in adapted in ARPB.]]>
