Este trabalho investigou a caracterização de uma bacia hidrográfica do Semiárido de Pernambuco e os efeitos da estiagem nas condições de uso e ocupação do solo por meio da adoção de geotecnologias aplicadas à gestão dos recursos hídricos. Para tanto, foram obtidas as imagens de altimetria pela Embrapa e realizada análise para caracterização morfométrica com o software QGIS e a extensão Terrain Analysis Using Digital Elevation Models – TauDEM. Além disso, se utilizaram as imagens de uso e ocupação do solo da plataforma do MAPBIOMAS BRASIL referente aos anos de 2011 e 2018 para analisar as modificações ocorridas durante o período de estiagem. A Bacia Hidrográfica do açude Cachoeira II apresenta forma alongada, o que indica uma baixa tendência a enchentes em condições normais de precipitação, baixa sinuosidade ocasionando uma maior velocidade de escoamento da água até o exutório e apresenta predominância das seguintes classes de relevo: suave ondulado e ondulado. Os dados de uso e ocupação demostraram que a maior ocupação da bacia é de formação do bioma Caatinga. A estiagem no período de 2012 a 2017 junto com a diminuição das áreas de caatinga e o aumento das áreas de pastagem favoreceram a ocorrência de erosão e o transporte de sedimentos na bacia, contribuindo para diminuição do açude Cachoeira II. Morphometric characterization and land use and occupation in a watershed in the semiarid of Pernambuco ABSTRACTThis work investigated the characterization of a watershed in the Semiarid of Pernambuco and the effects of the drought on the conditions of use and occupation of the soil through the adoption of geotechnologies applied to the management of water resources. For that, the altimetry images were obtained by Embrapa and an analysis for morphometric characterization was performed with the QGIS software and the Terrain Analysis Using Digital Elevation Models - TauDEM extension. In addition, the images of land use and occupation on the MAPBIOMAS BRASIL platform for the years 2011 and 2018 were used to analyze the changes that occurred during the drought period. The Cachoeira II reservoir watershed has an elongated shape, which indicates a low tendency to flooding under normal precipitation conditions, low sinuosity causing a faster flow of water to the exutory and presents predominance of the following relief classes: smooth undulating and wavy. The use and occupation data showed that the largest occupation of the basin is the formation of the Caatinga biome. The drought in the period from 2012 to 2017 together with the decrease in the caatinga areas and the increase in the pasture areas favored the occurrence of erosion and the transport of sediments in the basin, contributing to the decrease of the Cachoeira II reservoir.Keywords: MAPBIOMAS, QGIS, SRTM

Beberapa penelitian terkait kejadian hujan menggunakan beberapa jenis alat seperti Micro Rain Radar (MRR) dan Disdrometer. Kombinasi kedua instrument tersebut dapat memberikan gambaran yang lebih komprehensif mengenai kejadian hujan mulai dari lapisan atas atmosfer hingga permukaan. Penelitian ini mengamati beberapa kejadian hujan pada puncak musim hujan tahun 2017 dan pergantian tahun 2019/2020 di Kawasan Puspiptek Serpong, Tangerang Selatan dengan menggunakan instrumen MRR dan Disdrometer untuk mengetahui karakteristik distribusi ukuran butir air hujan. Hasil penelitian ini menunjukkan pola sebaran butir air hujan yang berbeda, antara kejadian hujan dengan intensitas sangat lebat dan sangat ringan hingga lebat, baik pada lapisan atas atmosfer maupun permukaan. Selain itu, hasil penelitian ini menunjukkan bahwa kejadian hujan sangat lebat berasal dari kumpulan awan konvektif dengan durasi hujan selama 15-60 menit. Sedangkan, kejadian hujan ringan hingga sedang pada umumnya berasal dari kumpulan awan nimbostratus di level menengah atmosfer dengan durasi hujan sekitar 2-3 jam.
Abstract
Several studies used some equipment types to observe rain events, such as the Micro Rain Radar (MRR) and Disdrometer. Combining the two can provide a more comprehensive picture of rain events from the upper atmosphere to the surface. This study observed several rain events at the peak of the rainy season in 2017 and the turn of the year 2019/2020 in the Puspiptek Serpong Area, South Tangerang, using MRR and Disdrometer instruments to determine the characteristics of the droplet size distribution. This study's results indicate a different droplet size distribution pattern, between the incidence of rain with very heavy intensity and very light to dense, both in the upper atmosphere and surface. Besides, this study's results indicate that the very heavy rain events come from convective clouds with a 15-60 minutes rain duration. Meanwhile, light to moderate rain events generally come from a group of nimbostratus clouds in the medium-level atmosphere with a rain duration of roundabout 2-3 hours.

AbstrakElemen seksual dalam novel Saman karya Ayu Utami masih sering dijustifikasi melalui nilai-nilai kesusilaan yang merupakan bagian dari dunia simbol. Penelitian ini merupakan penelitian deskriptif yang membahas karya tersebut dalam perspektif psikoanalisis-historis Slavoj Žižek. Metode psikoanalisis historis digunakan untuk melihat elemen seksual dalam karya Ayu Utami secara berbeda. Data dikumpulkan melalui pembacaan secara teliti dan berulang terhadap novel Saman untuk menemukan frasa, kalimat, paragraf, dan wacana yang memuat kualitas-kualitas subjek dialektis Slavoj Žižek. Data tersebut kemudian direlasikan untuk menentukan posisi subjek sebagai subjek radikal atau sebaliknya berdasarkan konsepsi pembentukan subjek radikal Žižek, yaitu konstruksi dunia simbolik-momen kekosongan-tindakan radikal-terbentuknya subjek radikal. Hasil penelitian ini menunjukkan bahwa tokoh dalam novel Saman, yaitu Laila dan Wisanggeni memiliki hasrat seksual yang lepas dari dominasi simbolik sehingga melakukan tindakan radikal. Melalui aktivitas seksual yang didorong hasrat yang murni tersebut, kedua tokoh tersebut memasuki momen kekosongan. Proses tersebut menyebabkan tokoh Laila dan Wisanggeni menjadi subjek radikal yang telah keluar dari dunia simbolik. Oleh karena itu, keberadaan subjek radikal dalam sebuah novel dapat dikatakan sebagai sebuah retakan dunia simbolik seksualitas yang secara ontologis konsisten. Kata kunci: seksualitas, tindakan radikal, psikoanalisis-historis Abstract The sexual element in “Saman” by Ayu Utami frequently is justified by the value of decency which becomes a part of the symbolic world. This study is descriptive research that discusses the novel from Slavoj Žižek’s historical-psychoanalysis perspective. The historical-psychoanalysis method consents to uncover the sexual element in the novel by Ayu Utami differently. Data collected through reading carefully and respectively of Saman novel are done to find out the phrases, sentences, paragraphs, and discourses that contain qualities of Slavoj Žižek’s dialectic subject. Collected data are then related to determining subject position as the radical subject or otherwise considering the construction of the symbolic world-ex nihilio- radical act-radical subject. The result of this research reveals that Laila and Wisanggeni characters in the novel of Saman have a sexual desire separated from symbolic dominance, and its practice becomes a radical act. Through sexual activity driven by passion, they enter the moment of the void. The process caused the figure of Laila and Wisanggeni to be a radical subject that has been out of the symbolic world. Therefore, the existence of a radical subject in a novel can be said to be a maligned symbolic world of sexuality ontologically consistent. Keywords: sexuality, radical act, historical-psychoanalysis

Published: July 2021

Ikan nila (Oreochromis niloticus) merupakan salah satu komoditas ikan air tawar yang banyak di budidayakan di Indonesia. Permasalahan dalam proses budidaya ikan secara intensif adalah penyediaan pakan komersial yang mencapai 60-70% dari total biaya produksi. Penyebab tingginya biaya penyediaan pakan komersial yaitu karena penggunaan bahan baku pakan ikan secara impor yang berakibat pada tingginya harga pakan ikan. Perlu dilakukan upaya untuk mendapatkan pakan alternatif yang lebih ekonomis dan mudah didapatkan. Upaya yang dilakukan untuk menekan biaya pakan adalah dengan memanfaatkan pakan hijauan, salah satunya yaitu menggunakan Lemna sp. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan efisiensi pakan pada ikan nila yang diberi Lemna sp. segar. Penelitian dilakukan pada Desember – April 2020 di Laboratorium Perikanan PSDKU Unpad di Pangandaran. Metode penelitian meggunakan eksperimental dengan Rancangan Acak Lengkap (RAL) yang terdiri atas empat perlakuan dan empat kali ulangan yaitu perlakuan A (kontrol), perlakuan B (15% Lemna sp.), perlakuan C (20% Lemna sp.) dan perlakuan D (25% Lemna sp.). Parameter uji pada penelitian ini yaitu laju pertumbuhan mutlak, efisiensi pakan dan kualitas air. Kemudian Pengamatan dilakukan selama 50 hari. Berdasarkan hasil penelitian, pemberian Lemna sp. segar dengan tingkat pemberian 20% menghasilkan laju pertumbuhan mutlak sebesar 11,2 g, efisiensi pakan sebesar 21,33% dan kualitas air yang masih dalam kisaran aman untuk pemeliharaan ikan nila.
