KAPASITAS POTENSI PARASITISME Trichogramma sp. (Hymenoptera: Trichogrammatidae) TERHADAP Corcyra sp.
Get PDFParasitism research Trichogramma sp. (Hymenoptera: Trichogrammatidae) has been carried out with the aim of studying the functional response of the parasitoid Trichogramma sp. Functional response is one measure to determine the effectiveness of a predator or parasitoid as an agent in biological control, so that it can express a change in the number of preys attacked by individual predators. Temperature is one of the most important host-parasitoid interactions in functional responses. The method used in the parasitoid parasitism Trichogramma sp. on the host Corcyra sp. using four levels of egg density Corcyra sp. with two different temperature treatments (27OC and room temperature). The results show the functional response model of the parasitoid Trichogramma sp. against its host Corcyra sp. described in the type I model. Parasitization level of Trichogramma sp. showed the same results for both temperature treatments, however, it also shows differences in the speed of predation. It also showed linearity between the parasitoids Trichogramma sp. with the host Corcyra sp. Parasitism rates are still increasing, along with an increase in host density. This research can be a starting point to improve the control of Corcyra sp. using the parasitoid Trichogramma sp. in the field
Rancang Bangun Alat Parut Modifikasi sebagai Teknologi Tepat Guna
Get PDFCoconut meat is one type of raw material that is most often used in the small food catering industry, where coconut processing is done by grating it. The process of grating coconut is sufficient to be done manually with a simple grater board if there are only a few, to produce a good grater, the speed of a manual grater requires approximately 3000 grating movements every hour. A coconut grater is a tool product for household needs that functions as a tool to crush coconuts into small granules, with the aim of obtaining the coconut milk contained in the coconut flesh. This study aims to design an appropriate technology in the form of a more ergonomic mid-scale modified coconut grater. From the test results obtained, the higher the rotational speed of the cylinder or the cutting speed of the grating knife, the higher the grating capacity. This is because the faster the cutting speed of the grating knife, the faster the cycle or frequency of grating.Daging buah kelapa merupakan salah satu jenis bahan baku yang paling sering digunakan indutri kecil catering makanan, dimana kelapa proses pengolahannya dilakukan dengan cara diparut. Proses pemarutan kelapa cukup dilakukan dengan manual dengan papan parut sederhana jika berjumlah sedikit, untuk menghasilkan parutan bagus, kecepatan parutan manual yang dibutuhkan kurang lebih 3000 gerakan parut setiap jam. Alat pemarut kelapa adalah salah satu produk alat untuk kebutuhan rumah tangga yang berfungsi sebagai alat untuk menghancurkan buah kelapa menjadi butiran-butiran kecil, dengan tujuan untuk memperoleh santan yang terkandung di daging buah kelapa. Penelitian ini bertujuan untuk merancang teknologi tepat guna berupa alat parut kelapa modifikasi skala menengah yang lebih ergonomis. Dari hasil pengujian yang diperoleh semakin tinggi kecepatan putar silinder atau kecepatan potong pisau parut maka semakin tinggi kapasitas pemarutan. Hal ini disebabkan karena semakin cepat kecepatan potong pisau parut maka siklus atau frekuensi pemarutan berlangsung lebih cepat

AKTIVITAS ANTIJAMUR PELAPUK KAYU NANOPARTIKEL KITOSAN-EKSTRAK N-HEKSAN DAGING BUAH KAYU GADIS (Cinnamomum parthenoxylon)
Get PDFThis study aims to synthesize chitosan nanoparticles - n-hexane extract of Cinnamomum parthenoxylon (CP) fruit using the ionic gelation method, to characterize them, and to determine their antifungal activity against the wood-rotting fungi Trametes versicolor and Fomitopsis palustris. Chitosan-CP extract nanoparticles were formulated with chitosan:Na-TPP:CP extract ratio of 1:1:0.5. Particle size and polydispersity index were determined using a particle size analyzer (PSA), and particles morphology was observed using a scanning electron microscope (SEM), and antifungal activity was measured using agar media. The results revealed that the average size of chitosan nanoparticles (base) was 276.9 nm, while the average size of chitosan-CP extract nanoparticles was 807.6 nm. The polydispersity index (PI) of both nanoparticles was greater than 0.7. Observations of the nanoparticles' morphology revealed that aggregation/agglomeration formed in the resulting particles. Both nanoparticles chitosan (base) and chitosan-CP extract inhibited the growth of white rot fungi (T. versicolor) more than brown rot fungi (F. palustris), as measured by the inhibitory zone
AKTIVITAS MASYARAKAT DAN PENGARUHNYA TERHADAP FENOMENA ALAM ABRASI TERINTEGRASI PEMBELAJARAN FISIKA SEKOLAH
Get PDFAbrasi merupakan proses alami berupa pengikisan tanah di daerah pantai yang disebabkan oleh gelombang dan arus laut yang merusak, kadang disebut juga erosi pantai. Kerusakan pantai tersebut salah satunya dapat disebabkan oleh terganggunya keseimbangan alam wilayah pesisir. Keausan umumnya disebabkan oleh fenomena alam, tetapi banyak tindakan manusia juga berkontribusi terhadap keausan pantai. Secara sederhana, abrasi adalah pengikisan wilayah pesisir oleh gelombang dan arus yang merusak. Adapun akibat yang ditimbulkan abrasi yaitu penyusutan garis atau area pantai, kerusakan hutan mangrove, permasalahan sampah dan pergeseran mata pencaharian masyarakat sekitar. Dibalik akibat yang ditimbul, ada beberapa hal yang dapat dilakukan dalam mitigasi (upaya) pencegahan dan pengurangan resiko abrasi. Mitigasi terbagi menjadi mitigasi struktural dan mitigasi non-struktural, untuk mitigasi struktural contohnya yaitu penanaman hutan mangrove dan membangun pemecah gelombang dan mitigasi non-struktural menekankan pada aspek perencanaan guna lahan, insentif pemerintah, pelatihan dan pendidikan bagi masyarakat, kesadaran publik. Upaya tersebut tentunya dapat dilakukan oleh pemerintah dan masyarakat sekitar. Termasuk warga sekolah yang berada di pesisir pantai. Guru dapat memberikan pembelajaran mitigasi bencana abrasi dengn mengintegrasikannya kedalam materi Gelombang fisika kelas XI
UJI DENSITAS DAN POROSITAS SERTA KARAKTERISASI BATU ANDESIT LETUSAN GUNUNG SEMERU DI DESA SUMBERULUH KECAMATAN CANDIPURO KABUPATEN LUMAJANG
Get PDFDensity and porosity tests are used to test and determine the quality of andesite stone resulting from the eruption of Mount Semeru. Andesite stone is used as an asphalt mixture in the PG Jatiroto area. The easy collapse of the asphalt road is the main factor of this research. The results of the density and porosity tests that have been carried out show quite good results. Where the results of the density test are in accordance with the indicator values on igneous rock. This means that the stone is sturdy enough to be used as an asphalt mixture. While the results of the andsit porosity test also showed good results. Therefore, these two tests can help researchers to find out the quality of the andesite stones used in the Jatiroto PG area. This andesite stone has a smooth texture. The size of the mineral grains is small and the distance is not too tight. The cavities are not too big so that there is still fluid to be absorbed into it.
Uji densitas dan porositas digunakan untuk menguji serta mengetahui kualitas batu andesit hasil letusan Gunung Semeru. Batu andesit digunakan sebagai bahan campuran aspal di kawasan PG Jatiroto. Mudah amblasnya jalanan aspal tersebut menjadi faktor utama penelitian ini. Hasil uji densitas dan porositas yang telah dilakukan menunjukkan hasil yang cukup baik. Dimana hasil uji densitas nilainya sesuai dengan nilai indikator pada batu beku. Artinya batu trsebut cukup kokoh untuk digunakan bahan campuran aspal. Sedangkan hasil uji porositas batu andsit juga menunjukkan hasil yang baik. Oleh karena itu kedua uji tersebut dapat membantu peneliti untuk mengetahui bagaimana kualitas batu andesit yang digunakan di kawasan PG Jatiroto. Batu andesit ini memiliki tekstur yang halus. Ukuran butir mineralnya yang kecil dan juga jaraknya yang tidak terlalu rapat. Rongga-rongganya yang tidak terlalu besar sehingga memungkinkan masih adanya fluida yang akan terserap ke dalamnya.
