<![CDATA[NTB has a large zeolite potential with a zeolite content percentage of 190,405 tons. One area that has great potential is the Selong belanak Central Lombok precisely at coordinates 8o51'48.5 "S 116o10'62.0" E mull mullet. Utilization of zeolite Lombok area is only used as a mixture of animal feed because it has not done research on its potential. One potential zeolite is its ability as an absorbent. Alcohol fermentation has not been able to be an alternative as a solution to energy problems. Alcohol fermentation only produces alcohols of less than 30% purity. This is caused by acetic acid byproducts that make microbes in the fermentation process can not breed optimally. From these problems need to be performed zeolite characteristic for optimal utilization. The purpose of this research is to find out the characteristics of natural zeolite of Selong belanak Lombok as an adsorbent in purifying alcohol of fermentation. The method of this research is descriptive with data collecting technique performed by zeolite characterization including cation exchange capacity with Schollenberger method, surface area using methylene blue method, absorption using Iodometry titration method, zeolite water content using gravimetric method and alcohol concentration determined by specific gravity and instrument GC-MS. Based on the result of natural zeolite research, Selong belanak Lombok has characteristic with natural cation zeolite exchange capacity of Selong Belanaq Lombok for 14,0894 meq / 100 gram. The zeolite surface area is 16, 3537 m2 / gram. Absorption zeolite to iodium is relatively low at 2.9357%. water content obtained from natural zeolite Selong Belanaq Lombok is 7.74%. After use of various alcoholic distillate absorbent fermentation alcohol concentration was obtained 81.4%. Based on the findings of natural zeolite researchers mullet tubes need to be activated more optimally to produce alcohols with purity above 99%, as laden mixture material in gasoline. ]]>

<![CDATA[Chemistry investigates interactions and reactions of particles as atom, ion, molecule, and their tendencies. Interactions occurred are so abstract that make them become difficult to be observed and documented. This becomes a problem in learning chemistry. It happens due to the separation of macroscopic and microscopic concepts. In fact, to be able to obtain the concept of chemistry as whole requires learning model which can integrate three aspects namely macroscopic, symbolic-conducted through practicum, and microscopic-conducted through modeling interactive media. This study aimed to developed interactive learning media for fundamental chemistry class. This study belongs to Educational Research and Development. In general, there were three steps conducted by the researcher namely analyzing, designing, and developing. Data obtained from this study was in the form of qualitative data consisted of suggestions and responses in likert scale.

<![CDATA[Mitra pengabdian ini adalah kelompok tani jamur sekecamatan pringgarata. Masalah yang paling banyak dikeluhkan petani jamur khususnya jenis merang dan tiram adalah produksi yang tidak menentu dan kualitas jamur yang sulit dipertahankan. Ada tiga komponen utama yang harus diperhatikan petani jamur untuk dapat menghasilkan panen jamur yang maksimal. Pertama jamur merupakan tumbuhan yang tidak berklorofil sehingga tidak dapat memproduksi makanannya sendiri. Jamur memperoleh maknannya dari media tumbuhnya. Jadi kualitas media tumbuh merupakan kunci untuk mendapatkan jamur dengan jumlah dan kualitas yang diharapkan. Kedua jamur rentan dengan perubahan iklim jadi petani harus mampu menciptakan lingkungan yang ideal untuk tumbuh kembang jamur. Faktor terahir yang biasanya berpengaruh dalam budidaya jamur adalah kontaminan penggangu yang biasanya hadir karena media tanam dan lingkungan yang kurang bersih atau tidak seteril. Ketiga faktor ini masih kurang dipahami oleh klompok tani jamur Desa Taman Indah Kecamatan Pringgarata sehingga hasil panennya masih belum maksimal. Ketiga faktor tersebut yang menjadi fokus tim pengabdian untuk diberikan kepada mitra untuk mendapatkan hasil panen jamur yang maksimal. Target dalam pengabdian ini adalah klompok tani dapat membuat media tanam yang ideal untuk tumbuh kembang jamur. Klompok tani juga mampu membuat larutan formalin untuk sterilisasi lingkungan media tanam jamur. Hasil kegiatan ini petani jadi lebih mehami teknik pengomposan dan kontaminan yang harus diatasi. Petani jamur memiliki keterampilan dalam merekayasa ikilim kumbung jamur untuk dapat menghasilkan produk jamur yang maksimal. Produksi maksimal ekonomi petani jamur terangkat ditengah kondisi ekonomi yang tidak menentu. Iointerprenership Skill Capital Success Post-Covid-19 Pandemic This service partner is a mushroom farmer group in the Pringgarata sub-district. The problem that most mushroom farmers complain about, especially the types of straw and oysters is the erratic production and the quality of the mushrooms that are difficult to maintain. There are three main components that must be considered by mushroom farmers to be able to produce maximum mushroom harvests. First, fungi are plants that do not contain chlorophyll, so they cannot produce their own food. Mushrooms derive their meaning from their growing medium. So the quality of the growing media is the key to getting mushrooms with the expected quantity and quality. Both mushrooms are vulnerable to climate change so farmers must be able to create an ideal environment for mushroom growth. The last factor that usually affects mushroom cultivation is nuisance contaminants which are usually present due to the planting media and an environment that is not clean or not sterile. These three factors are still poorly understood by the mushroom farmer group in Taman Indah Village, Pringgarata District so the harvest is still not optimal. These three factors are the focus of the dedicated team to give to partners to get maximum mushroom yields. The target of this service is that farmer groups can make ideal planting media for mushroom growth. Farmer groups are also able to make formalin solutions for the environmental sterilization of mushroom growing media. As a result of this activity, farmers have a better understanding of composting techniques and the contaminants that must be overcome. Mushroom farmers have skills in engineering the lumbung mushroom climate to be able to produce maximum mushroom products. The maximum economic production of mushroom farmers is raised amid uncertain economic conditions. ]]>

<![CDATA[Lingkungan, kualitas media, teknik inokulasi bibit dan kualitas bibit menjadi beberapa faktor yang mempengaruhi produktivitas jamur merang. Kondisi lingkungan menjadi salah satu faktor utama. Kondisi lingkungan ideal harus terus dijaga petani jamur merang, produksi jamur merang tetap setabil. Suhu ruangan menjadi faktor yang harus diperhatikan untuk menjaga tumbuh kembang jamur merang. Suhu ruangan bisa ideal jika kondisi kumbung dan kualitas media terjaga. Peneliti ini bertujuan menganilsa produktivitas kumbung selama satu tahun pertama produksi. Produktivitas diukur melalui lama produksi dan massa jamur merang yang diperoleh. Produksi jamur merang rata-rata dalam setiap bulannya sebesar 103,7 Kg dengan lama produksi rata-rata 30 hari. Korelasi anatara jumlah produksi dan lama panen berkorelasi positif ini dibuktikan dengan nilai R hitung 0,978>R tabel 0, 4575. Berdasarkan kajian lapangan dan analisis data diperoleh jumlah produksi berkorelasi positif dengan lama panen dan produksi jamur dan akan menurun seiring bertambahnya usia kumbung. Menurunnya produktivitas diakibatnya karena menurunnya kualitas media tanam. Kontaminan dan sulitnya merekayasa iklim kumbung menjadi faktor lain yang berpengaruh terhadap menurunnya jumlah dan lama produksi jamur merang. Analysis of the Length of Use of Kumbung on the Productivity of Straw Mushrooms (Volvariella volvaceae) Abstract The environment, the quality of the media, the inoculation technique of seedlings and the quality of seedlings are some of the factors that affect the productivity of the straw mushrooms. Environmental conditions are one of the main factors. Ideal environmental conditions must be maintained by straw mushroom farmers, the production of straw mushrooms remains as stable as possible. Room temperature is a factor that must be considered to maintain the growth and development of straw mushrooms. Room temperature can be ideal if the condition of the kumbung and the quality of the media are maintained. This researcher aims to analyze the productivity of the kumbung during the first year of production. Productivity is measured through the length of production and the mass of the acquired straw mushroom. The average production of straw mushrooms in each month is 103.7 Kg with an average production duration of 30 days. The correlation between the amount of production and the duration of harvest is positively correlated with the calculated R value of 0.978>R table 0.4575. Based on field studies and data analysis, the amount of production is positively correlated with the length of harvest and mushroom production and will decrease with age. The decline in productivity is due to the decline in the quality of the growing media. Contaminants and the difficulty of engineering a continuous climate are other factors that influence the decrease in the number and duration of straw mushroom production.]]>
