Abstract

Drosophila melanogaster or commonly known as the fruit fly, is a type of insect found in rotting fruits or vegetables and plants material around the world with a wide distribution. This study aims at determining the LC50 value of eggs, larvae, pupae and the reproductive potential of adult fruit flies (Drosophila melanogaster) exposed to cypermethrin. The method used was an experiment using a completely randomized design (CRD). The data of mortality from toxicity tests were analyzed by ANOVA and Probit test using the SPSS application, while data on reproductive potential parameters were analyzed using the life table method using Ms. Excel. The results of this study showed that the LC50 value of cypermethrin was different at each development stage. The LC50 value from the lowest to the highest successively starts at the egg development stage, which was 1654,824 ppm, then at the egg stage was 3067,192 ppm, the imago stage was 3155,848 ppm and the pupae stage was 3755,014 ppm. The reproductive potential and population rate of D. melanogaster decreased significantly with increasing concentration, lower than the control. The best concentration that was able to reduce the value of the net reproduction rate (R0) and the ability of the population to multiply (λ) was 266.6 ppm with an average value of 0.22 and 0.86, respectively. Further, the best concentration in reducing the average life period (T) and the population reproductive potential (rm) were a concentration of 250.0 ppm with an average value of each parameter of 9.64 and -0.03.

Abstract

German cockroach (Blattella germanica L.) is one of the important residential pest insects, because of its role as a vector of disease. To reduce its population, it can be used with bait techniques. However, there was a rejection of glucose against German cockroaches against phagostimulant-based commercial bait. Therefore it is necessary to review the phagostimulant as a component of the bait to minimize failure to control German cockroaches based on bait using German cockroaches strain VCRU (Vector Control Research Unit). The first step to formulating the bait is to find the phagostimulant most sought by German cockroaches. The ingredients used as fagostimlan are sugar, durian, erythritol, and banana. The purpose of this study was to determine the behavior of choosing German cockroaches against bait with different phagostimulants and the peak of feeding activity in German cockroaches. This study used an experimental method with a Completely Randomized Design (CRD) consisting of 4 treatments giving phagostimulant and repeated 4 times divided into four test arenas. The treatment consisted of bait which each contained sugar, durian, erythritol, and banana as phagostimulants. Observation of behavior using the method of behavior sampling is recorded in continuous recording for 24 hours using a Closed Circuit Television (CCTV) camera. The parameters measured were latency, frequency, duration, and peak feeding activity of German cockroaches. The data were analyzed with ANOVA at p <0.05. The results showed that the behavior of selecting cockroaches from the VCRU strain on the bait was not significantly different (p<0.05) and was attracted to all feeds provided, but gel bait with sugar phagostimulant was the preferred bait by looking at the three parameters of latency, frequency, and duration. The results of the average latency in the VCRU strain to the durian gel for 17 minutes, the average frequency of most visits to the sugar gel in the VCRU strain by 10 times, the longest average duration of the VCRU strain gel for 1 minute 46 seconds and peak eating activity VCRU strains occur between 17:00 - 20:00.

Abstract

Flood in Indonesia has become familiar to see and to experience in every rainy season. Flood has been national problem so that it needs a special board named Disaster Overcome Board. Flood is a condition where an area is submerged because of water volume increase. To minimize flood disaster so it needs disaster prevention which is called disaster mitigation both structurally and nonstructurully. Mitigation is a the first step of natural disaster privention to minimize and to decrease disaster impact either before, during, or after flood. This model is tried out in Bojonegoro and Sampang Regencies because these both regencies are prone to flooding in East Java. The learning was conducted at the Centers for Teaching and Learning Activity RA. Kartini, Lestari and Nurul Ummah in Bojonegoro Regency and one Center for Teaching and Learning Activity Ibu Pertiwi in Sampang Regency. The purpose of this model is to describe the quality and effectivity of texts about learning model development of flood disaster mitigation in multiliteracy education abd its devices in desaster mitigation learning process at multi literacy education. As for the model products are learning texts, the guide of learning result assessment and the guide of learning media, the simulation of disaster alert and posters which are distributed and as references for institution unit of the Center of Teaching and Learning Activity in carrying out the learning of flood desaster mitigation in multiliteracy education. The process of this model learning conducted by the Center of Teaching and Learning Activity refers to the Standard of Graduate Competency of multiliteracy education which emphasizes on attitude dimention, knowledge dimention, and skill dimention. The approach used in this learning process is andragogy approach and quantum learning in its learning process, followed by 20 persons persons per group, spent 29 sessions each of which takes three hours. Banjir di Indonesia sudah menjadi sesuatu yang lazim dilihat dan dialami setiap musim penghujan. Banjir sudah menjadi masalah nasional sehingga dibentuklah sebuah badan khusus yang disebut Badan Penanggulangan Bencana. Banjir adalah terendamnya suatu daerah karena volume air yang meningkat. Untuk mengurangi bencana banjir maka diperlukan penanggulangan bencana yang disebut mitigasi bencana baik secara struktural maupun nonstruktural. Mitigasi merupakan tahap awal penanggulangan bencana alam untuk mengurangi dan memperkecil dampak bencana baik sebelum, saat dan setelah banjir. Model ini diujicobakan di Kabupaten Bojonegoro dan Kabupaten Sampang, karena kedua kabupaten ini merupakan daerah rawan bencana banjir di Jawa Timur, pembelajaran dilakukan di PKBM RA. Kartini, PKBM Lestari dan PKBM Nurul Ummah Kabupaten Bojonegoro dan satu di PKBM Ibu Pertiwi Kabupaten Sampang. Tujuan model ini adalah untuk Mendeskripsikan kualitas dan kefektifan naskah pengembangan model pembelajaran mitigasi bencana banjir pada pendidikan multikeaksaraan dan perangkatnya didalam proses pembelajaran mitigasi bencana pada pendidikan multikeaksaraan. Adapun produk model ini berupa naskah pembelajaran, panduan penilaian hasil belajar dan panduan media pembelajaran, simulasi beberan tangguh bencana dan poster yang kemudian dijadikan acuan bagi satuan lembaga PKBM dalam penyelenggaraan pembelajaran mitigasi bencana banjir pada pendidikan Multikeaksaraan. Proses Pembelajaran model ini dilakukan oleh PKBM adalah mengacu pada SKL pendidikan multikeaksaraan yang menekankan pada dimensi sikap, dimensi pengetahuan dan keterampilan, pendekatan yang digunakan dalam proses pembelajaran ini adalah pendekatan andragogi dan quantum learning dalam proses pembelajarannya, yang diikuti sebanyak 20 orang perkelompok, dimana jumlah jam pelajaran didalam proses pembelajaran ini adalah sebanyak 29 kali pertemuan dengan 1 kali pertemuan sebanyak 3 jam pelajaran.
