Abstract

The objective of this study was to evaluate the physiological response of the cabbage head caterpillar Crocidolomia pavonana treated with an active fraction of Calophyllum soulattri bark extract. Extraction of the test plant materials were performed with maceration method using methanol, continued by counter-current distribution separation in ethylacetate and water. Methanol fractionation of C. soulattri was performed by vaccuum liquid chromatography and the bioassays were conducted by a leaf-feeding method. The results showed that the dichloromethane fraction of C. soulattri had strong insecticidal activity against C. pavonana larvae, with LC50 of 0.05%. Sublethal treatments with the active fraction at LC15, LC50, and LC85 reduced the relative growth rate of the fourth instars by 48.9-94.1%. The treatments with the fraction at LC15 and LC50 to the fourth instars reduced the activity of invertase and protease enzyme by 20.7-24.1 and 14.4-25.14%, respectively, but increased the activity of trehalase by 26.7-120% as compared with controls. Key words: Physiological response, Crocidolomia pavonana, Calophyllum soulattri, botanical insecticide

Abstract

Research on absorption of gaseous SO2 from factory emissions of nickel ore industry using solution of ammonium hydroxide has been done. Research conducted with variations including concentration, temperature, and time of contact. Variation of the concentration used were 1%, 2%, 3%, 4% and 5%; while variations of the temperature  used were 20oC, 25oC, 30oC, 35oC, and 40oC; and the contact time were 10, 15, 20, 25 and 30 minutes. SO2 gas emissions sampling is done at a time when the factory operates at flow velocity and temperature conditions exhaust gas emissions. Results showed the greater concentration of the solution absorbing the greater the concentration of sulfur dioxide gas absorption, absorption temperature range between 30° C-40° C, and the longer the absorption of the greater number of SO2 absorption. A comparison of the percentage of the results of the average accumulation of absorption between absorbent solution (ammonium hydroxide) and slurry of calcium carbonate to reduce sulfur dioxide emissions to ambient air showed results still under the limestone slurry i.e. absorption capability comparison 95.00%: 62,91%. Difference in SO2 gas that is not absorbed out as emissions are still on top of the raw set quality standard (750 mg/m3). The gas is absorbed to form ammonium sulphate compounds that could be accommodated and packaged for commercialized as a by-product in the form of inorganic fertilizers valued economically. As such, ammonium hydroxide is used as an alternative to allow compound absorbent and produces no side residue so that the result is considered safe for the environment.

Abstract

Literacy education was initially limited to efforts to provide basic reading, writing and numeracy skills. Then it developed into literacy in various ways not just reading and writing but also literacy in various aspects of life. The regulation was made by the government which emphasized that through literacy education in two forms, namely basic literacy education and advanced literacy education in the form of independent business literacy and multi-literacy. In terms of advanced literacy education it is essentially based on the study that with advanced literacy education not necessarily the community-students are able to empower themselves as they deserve. This is related to the problem of continuity of learning activities and achievement motivation. If students after advanced literacy education can carry out continuous learning activities reinforced by the presence of achievement motivation, it is possible for them to strengthen their literacy abilities. It can be concluded that the continuity of learning activities and achievement motivation allows students to empower themselves in literacy. Pendidikan keaksaraan awalnya terbatas pada upaya memberikan kemampuan membaca, menulis dan berhitung dasar. Kemudian berkembang menjadi keaksaraan dalam berbagai hal tidak hanya sekedar baca tulis hitung tetapi juga keaksaraan dalam berbagai aspek kehidupan. Regulasi pun dibuat oleh pemerintah yang menegaskan bahwa melalui pendidikan keaksaraan dengan dua bentuk yaitu pendidikan keaksaraan dasar dan pendidikan keaksaraan lanjutan berupa keaksaraan usaha mandiri dan multikeaksaraan. Dalam hal pendidikan keaksaraan lanjutan secara esensi berdasarkan kajian bahwa dengan pendidikan keaksaraan lanjutan tidak serta merta masyarakat- peserta didik mampu memberdayakan dirinya sebagaimana layaknya. Hal ini terkait dengan persoalan kontinuitas kegiatan belajar dan motivasi berprestasi. Jika peserta didik pasca pendidikan keaksaraan lanjutan dapat melakukan kontinutas kegiatan belajar diperkuat oleh adanya motivasi berprestasi, maka dimungkinkan mereka semakin kuat kemampuan keberaksaraannya. Dapatlah disimpulkan bahwa dengan kontinuitas kegiatan belajar dan motivasi berprestasi memungkinkan peserta didik dapat memberdayakan dirinya dalam keberaksaraan

Abstract

Komisi Pemilihan Umum (KPU) telah menetapkan pasangan calon serta mengundi nomor urut masing-masing kontestan yang akan berlaga. Sesuai tahapan Pilkada sebagaimana diatur dalam PKPU Nomor 5 Tahun 2020, tahapan kampanye dimulai 26 September hingga 5 Desember 2020. Masyarakat sebagai pemilih mesti mengetahui proses yang bakal dilalui para pasangan calon. Hal demikian penting, guna meyakinkan betul siapa yang layak dipilih guna mengisi kursi kepemimpinan berikutnya. Dalam Pilkada ada tahapan-tahapan yang harus dilalui oleh para calon peserta Pilkada. Selain para calon peserta Pilkada yang perlu mengetahui tahapan-tahapannya, masyarakat pun juga perlu untuk mengetahui tahapan-tahapan tersebut agar mereka mengetahui proses demokrasi yang sedang berlangsung tersebut. Namun dalam kondisi pandemi Covid-19 ini bisa dibilang Pilkada yang dilakukan ini, akan beresiko menambah kluster Covid-19 ini pada masa kampanye Pilkada, kita mengetahui bahwa dalam peserta demokrasi seperti Pilkada agak susah untuk menertibkan para peserta Pilkada untuk tidak melakukan pengerahan massa dalam melakukan kampanye, karena kampanye adalah salah satu cara bagi para calon Kepala Daerah untuk meraup suara para pemilihnya agar bisa memenangkan Pilkada ini. Perlu adanya solusi yang tepat untuk mencegah menyebarnya Covid 19 ini pada masa Pilkada kali ini, pemerintah dan masyarakat harus bersatu untuk masing-masing menjalankan perannya agar penyebaran Covid 19 tidak semakin parah dalam masa Pilkada. Perlu adanya pemahaman dan sosialisasi yang disampaikan oleh pemerintah dalam hal ini Komisi Pemilihan Umum dan juga Kementerian Kesehatan agar masyarakat tetap menjalankan protokol Kesehatan selama masa Kampanye dan juga pada saat pencoblosan, agar penyebaran Covid 19 ini tidak semakin menyebar dengan adanya pesta demokrasi yang dilakukan diberbagai daerah di Indonesia.

Abstract

Pada masa ini, kemajuan Ilmu pengetahuan dan Ilmu teknologi sangat pesat sehingga memudahkan masyarakat dalam mengakses segala hal salah satunya informasi. Seiring perkembangannya, kemajuan teknologi ini tidak hanya memberikan dampak positif tetapi juga memberikan dampak negatif. Dalam mengakses informasi saat ini, penyampaian akan informasi sangat mudah dan  cepat. Dimana seseorang dengan sangat mudah memproduksi informasi dan membagikannya lewat media sosial seperti Facebook, Twitter, Instagram, Google, Youtube ataupun pesan genggam seperti WhatsApp, LINE, BBM (Blackberry Messenger) dan lain sebagainya yang tidak dapat disaring dengan baik.Media sosial merupakan media bersifat Online Tools yang memfasilitasi interaksi antar penggunanya dengan cara pertukaran informasi, pendapat dan permintaan. Melalui media sosial dan alat elektronik seperti Smartphone, informasi  yang dikeluarkan oleh perseorangan maupun badan usaha sangat mudah tersebar dan dibaca oleh banyak orang. Informasi yang telah dibaca dapat mempengaruhi emosi, perasaan, pikiran bahkan tindakan baik individu maupun kelompok. Sangat disayangkan apabila media sosial digunakan untuk memperoleh dan memberikan informasi yang tidak akurat apalagi sampai menjadikan media sosial sebagai alat penyebaran berita bohong (hoax) dengan menggunakan judul yang sangat memprovokasi untuk mengarahkan para pembaca kepada opini publik yang negative. Hoax adalah usaha untuk menipu atau mengakali pembaca/pendengarnya untuk mempercayai sesuatu, padahal sang pencipta berita palsu tersebut tahu bahwa berita tersebut adalah palsu. Salah satu contoh pemberitaan palsu yang paling umum adalah mengklaim sesuatu barang atau kejadian dengan suatu sebutan yang berbeda dengan barang/kejadian sejatinya. Suatu pemberitaan palsu berbeda dengan misalnya pertunjukan sulap; dalam pemberitaan palsu, pendengar/penonton tidak sadar sedang dibohongi, sedangkan pada suatu pertunjukan sulap, penonton justru mengharapkan supaya ditipu. Berita bohong (hoax) perlu mendapatkan perhatian serius pada saat ini karena hoax sendiri adalah “Tindakan komunikasi yang dilakukan oleh suatu individu atau kelompok dalam bentuk provokasi, hasutan, ataupun hinaan kepada individu atau kelompok yang lain untuk membuat keadaan menjadi tidak teratur dan memicu pertengkaran, perdebatan serta perpecahan bagi seseorang, kelompok ataupun bangsa dan negara. Hal ini dilakukan oleh orang-orang yang tidak bertanggung jawab untuk mendapatkan keuntungan baik secara psikologis maupun keuntungan finansial.

Abstract

ABSTRAK  Pentingnya kesadaran mewujudkan pertahanan dan keamanan bangsa di era revolusi industri bagi generasi muda dalam menjaga kedaulatan bangsa. Sebagai warga negara memiliki hak dan kewajiban dalam upaya bela negara dan upaya pertahanan keamanan (pasal 27 ayat 3 dan pasal 30 ayat (1) UUD 1945). Diatur lebih rinci lagi dalam Undang-Undang Nomor 20 Tahun 1982, tentang Ketentuan-Ketentuan Pokok Pertahanan Keamanan Negara Republik Indonesia. Globalisasi yang begitu pesatnya membuat semakin derasnya beragam kebudayaan asing, yang menjadi kendala ketika generasi muda tidak memiliki pegangan dalam menerima semua informasi yang masuk sehingga tidak menyaring mana yang patut dijadikan pengetahuan dan mana yang harus disingkirkan karena tidak sesuai dengan kepribadian bangsa. Generasi muda salah satunya siswa kelas XI Madrasah Aliyah Daarul Hikmah sudah terbiasa memegang gadget sejak kecil. Pengenalan teknologi dan dunia maya membuat mereka sering berselancar di media sosial sehingga terjadi interaksi dengan beragam karakter orang tanpa ada batasan ruang dan waktu ini sangat berpengaruh pada perkembangan kehidupan dan kepribadian. Jika digunakan secara bijak justru adanya media sosial ini bisa digunakan sebagai sarana menggalang persatuan anak muda bangsa untuk menjalin komunikasi, bertukar pikiran, mengenalkan kebudayaan bangsa ke negara lain yang memiliki keindahan alam di dalamnya untuk kemajuan bangsa dengan beragam keberagaman budaya yang dimiliki justru bukan mempermudah perpecahan. Namun, berdasarkan hasil observasi yang dilakukan, ditemukan bahwa peserta didik: Kurang bijak dalam mengatur waktu dalam menggunakan media sosial, Ketertarikan terhadap budaya asing yang tidak sesuai dengan kepribadian bangsa, Menurunnya rasa nasionalisme, dan Rendahnya etika bermedia sosial. Oleh sebab itu, tim Pengabdian kepada Masyarakat memutuskan terjun dan menawarkan solusi permasalahan dengan memberikan sosialisasi terhadap siswa kelas XII Madrasah Aliyah Daarul Hikmah tentang pentingnya mewujudkan pertahanan dan keamanan bagi generasi Z di era media sosial. Sosialisasi menggunakan metode ceramah interaktif yang bertujuan meningkatkan kreatifitas dan keaktifan siswa dengan adanya diskusi serta sesi tanya jawab. Para siswa akan diberikan penjabaran terkait karakteristik generasi Z yang dekat dengan media sosial, dampak positif dan negative dari media sosial, menggunakan media sosial sebagai sarana meningkatkan rasa nasionalisme sehinga memiliki kesadaran pentingnya meningkatkan kontribusi dalam pertahanan dan keamanan. Kata-kata Kunci: Keamanan, Media Sosial, Pertahanan  ABSTRACT  The importance of awareness of realizing the defense and security of the nation in the era of the industrial revolution for the younger generation in maintaining the sovereignty of the nation. As citizens have rights and obligations in efforts to defend the state and defense efforts for security (article 27 paragraph 3 and article 30 paragraph (1) of the 1945 Constitution). It is regulated in more detail in Law Number 20 of 1982, concerning the Basic Provisions of State Security Defense of the Republic of Indonesia. Such rapid globalization has made the influx of various foreign cultures, which becomes an obstacle when the younger generation does not have a handle in receiving all incoming information so that it does not filter out which ones should be used as knowledge and which ones should be removed because they are not in accordance with the personality of the nation. The younger generation, one of which is a class XI student of Madrasah Aliyah Daarul Hikmah, has been accustomed to holding gadgets since childhood. The introduction of technology and cyberspace makes them often surf social media so that there is interaction with various characters of people without any restrictions on time and space, this greatly affects the development of life and personality. If used wisely, the existence of social media can be used as a means of rallying the unity of the nation's youth to establish communication, exchange ideas, introduce the nation's culture to other countries that have natural beauty in it for the progress of the nation with a variety of cultural diversity that is owned instead of facilitating division. However, based on the results of observations made, it was found that students: Lack of wisdom in managing time in using social media, Interest in foreign cultures that do not match the personality of the nation, Decreased sense of nationalism, and Low ethics of social media. Therefore, the Community Service team decided to jump in and offer solutions to problems by providing socialization to class XII students of Madrasah Aliyah Daarul Hikmah about the importance of realizing defense and security for generation Z in the era of social media. Socialization uses an interactive lecture method that aims to increase student creativity and activity with discussions and question and answer sessions. Students will be given an explanation of the characteristics of generation Z who are close to social media, the positive and negative impact of social media, using social media as a means of increasing the sense of nationalism so as to have an awareness of the importance of increasing contributions in defense and security. Keywords: Security, Social Media, Defense

Abstract

This study aims to describe the implementation of academic supervision at STIKes Budi Luhur Cimahi and analyze its influence on improving lecturers' performance and competence. Academic supervision is an important part in supporting the implementation of the Tridharma of Higher Education, especially in the fields of teaching, research, and community service. This study uses a qualitative descriptive approach with data collection techniques through in-depth interviews, direct observation, and analysis of academic documents. The results of the study indicate that academic supervision at STIKes Budi Luhur Cimahi is carried out in a structured manner through the Quality Assurance Unit (UPM) with a focus on class observation, student surveys, and evaluation of learning documents. Supervision has a positive impact on improving lecturers' competence, especially in designing practice-based learning strategies that are relevant to the needs of the world of work in the health sector. However, the implementation of supervision still faces obstacles such as limited supporting facilities, lack of training for supervisors, and lecturers' resistance to the supervision process. This study concludes that effective academic supervision is not only an evaluation tool, but also an instrument to support the continuous professional development of lecturers. Strategic recommendations include improving learning facilities, routine training for lecturers and supervisors, and a more collaborative supervision approach. With these steps, STIKes Budi Luhur Cimahi can continue to improve the quality of education and produce competent graduates in the health sector.
