ABSTRAK Penelitian telah dilakukan pada kotak modifypolystyrene sebagai kotak pengiriman kubis segar menggunakan es kering sebagai media pendingin. Penelitian ini bertujuan untuk menguji kotak yang dimodifikasi untuk mengetahui kotak yang paling cocok dimodifikasi untuk menjaga kesegaran sayuran. Kotak polystyrene yang dimodifikasi dibuat dengan memisahkan kotak menjadi dua kompartemen, satu kompartemen untuk menempatkan es kering sebagai media pendingin, dan kompartemen lain untuk menyimpan kubis segar. Itu dibuat lima jenis kotak dimodifikasi, dua jenis media pendinginan mondar-mandir di bawah sayuran segar, sedangkan jenis sisanya menempatkan media pendingin di atas sayuran. Tes yang dilakukan selama 7 jam terdiri dari suhu di sekitar kotak, suhu di dalam kotak, dan suhu pusat kubis segar. Pengukuran lain yang dilakukan adalah berat es kering yang digunakan selama penyimpanan dingin, penurunan berat kubis segar, pengamatan visual kerusakan kubis segar, dan perhitungan keseimbangan energi. Menempatkan es kering di bawah kubis segar menyebabkan suhu tengah kubis segar jauh di atas suhu penyimpanan yang disarankan, 0oC, sementara menempatkan media pendingin di atas sayuran memberi dampak negatif pada sayuran di mana suhu tengah kubis segar di bawah 0oC untuk dua jenis kotak yang dimodifikasi, kecuali es kering yang ditempatkan di baskom yang terbuat dari piring zink. Berdasarkan perhitungan energi, terungkap bahwa hampir lebih dari 75% energi pendingin digunakan untuk mengatasi beban pendinginan di sekitarnya. Ditemukan bahwa kotak modifikasi yang paling cocok untuk menyimpan kubis segar adalah jenis kelima. ABSTRACT Research had been carried out to modify polystyrene box as fresh cabbage delivery box using dry ice as a cooling medium. The research aims were to find out the most suitable model box to maintain the freshness of the vegetables. Modified polystyrene box was made by separating the box into two compartments, one compartment for placing dry ice, and another compartment for storing the fresh cabbage. The box was modified into five types which consisted of two types of the box where the cooling medium was placed below the fresh vegetable, while for the rest, the cooling medium was placed above the vegetable. The tests were performed for 7 hours with the hourly observation that consisted of the temperature surrounding the model box, temperature inside the box, and temperature of the center of the fresh cabbage. Other conducted measurements were the weight of dry ice used during cold storage, weight loss of fresh cabbage, visual observation on the deterioration of the fresh cabbage, and energy equilibrium calculation. Placing dry ice below the fresh cabbage caused the center temperature of the fresh cabbage to far above the recommended storing temperature, 0oC, while placing the cooling medium above the vegetable gave a negative impact on the vegetable where the center temperature of the fresh cabbage was below 0oC for the two types of model boxes, except for the fifth type box where dry ice was placed in a basin made of zink plate. Based on energy calculation it was revealed that almost more than 75% of cooling energy was used to overcome the surrounding cooling load. It was found that the most suitable model box for storing the fresh cabbage was the fifth type.

Abstrak Peningkatan hasil panen jamur tiram berperan penting dalam upaya memenuhi permintaan pasar dan diharapkan mampu meningkatkan kesejahteraan petani. Penelitian ini dilakukan untuk melihat pengaruh konsentrasi penambahan EM4 pada fermentasi media tanam serta kendali suhu dan kelembaban lingkungan terhadap karakteristik fisik jamur tiram, dan juga interaksi terbaik dari kedua perlakuan. Penelitian menggunakan Rancangan Acak Kelompok faktorial dengan dua faktor perlakuan yaitu penambahan EM4 (tanpa EM4, 2, 4, 6, 8, dan 10 mL/baglog) dan kendali suhu dan kelembaban (lingkungan terkendali secara konvensional dan otomatis). Setiap perlakuan dibuat tiga kali ulangan. Hasil penelitian menunjukkan bahwa perlakuan penambahan EM4 dan kendali suhu dan kelembaban memiliki pengaruh nyata terhadap berat segar badan buah dan panjang tangkai. Interaksi perlakuan penambahan EM4 dan kendali suhu dan kelembaban berpengaruh nyata terhadap panjang tangkai, akan tetapi tidak berpengaruh kepada parameter berat segar badan buah, jumlah badan buah, diameter tudung, dan umur panen pertama. Penambahan EM4 4 ml/baglog dan lingkungan terkendali secara otomatis merupakan interaksi perlakuan yang menghasilkan karakteristik fisik jamur tiram terbaik. Karakteristik fisik yang dihasilkan yaitu berat segar badan buah 125,8 g, jumlah badan buah 21 buah, diameter tudung 6,92 cm, panjang tangkai 7,5 cm, dan umur panen pertama 24 hari. Abstract Increasing the yield of oyster mushrooms plays an important role to meet market demand and is expected to improve the welfare of farmers. This research was conducted to see the effect of the concentration of EM4 addition on the fermentation of the growing media as well as the control of environmental temperature and humidity on the physical characteristics of oyster mushrooms, and also the best interaction between the two treatments. The study used a factorial randomized block design with two treatment factors, namely the addition of EM4 (without EM4, 2, 4, 6, 8, and 10 mL/baglog) and temperature and humidity control (conventional and automatic controlled environment). Each treatment was made three times replication. The results showed that the addition of EM4 treatment and control of temperature and humidity had a significant effect on fresh fruit body weight and stalk length. The interaction of the addition of EM4 treatment and control of temperature and humidity significantly affected stalk length but did not affect the parameters of fresh fruit body weight, number of fruit bodies, hood diameter, and age of the first harvest. The addition of EM4 4 ml/baglog and controlled environment automatically is an interaction treatment that produces the best physical characteristics of oyster mushrooms. The physical characteristics produced were 125.8 g fresh fruit body weight, 21 fruit bodies, 6.92 cm hood diameter, 7.5 cm stalk length, and 24 days of the first harvest.

ABSTRAK Berkurangnya ketersediaan air irigasi dapat disebabkan oleh debit air sungai yang turun pada musim kemarau, hilangnya air pada saluran irigasi, dan evaporasi. Dengan demikian, upaya-upaya penghematan perlu dilakukan seperti sistem pergiliran dalam pemberian air irigasi dan proposi dalam ditribusi air irigasi pada setiap subak. Penelitian dilakukan untuk mengetahui persentase pengehematan air irigasi yang ada pada suatu subak dan proposi pemberian air irigasi pada saat kurangnya ketersediaan air. Perolehan data primer dilakukan dengan metode wawancara, pengamatan, dan pengukuran sedangkan data sekunder diperoleh dari BMKG Wilayah III Denpasar. Data yang dikumpulkan selanjutnya akann dianalisis untuk mencari persentase pengehematan yang terjadi pada saat kekurangan air dan proposi distribusi air irigasi. Hasil penelitian menunjukan metode pergiliran dilakukan pada saat debit air tersedia tidak bisa memenuhi kebutuhan air irigasi. Metode pergiliran dilakukan pada subak bagian tengah dan subak bagian hulu pada bulan April sampai Mei. Metode pergiliran dilakukan dengan menurunkan jumlah kebutuhan air irigasi dan memberikan air irigasi sesuai dengan debit tersedia dengan rentang waktu setiap dua hari. Subak bagian hulu tidak terjadi penghematan karena proses pergiliran tidak berjalan, penghematan air irigasi pada subak bagian tengah rata-rata sebesar 28,3 persen dan subak bagian hilir sebesar 24 persen. Dengan penerapan metode pergiliran pada saat kekurangan air irigasi kebutuhan air irigasi bisa terpenuhi oleh debit air yang tersedia. Untuk mencapai proposional penghemtan air irigasi pada bulan April sampai Mei, pada subak bagian hulu air irigasi diturunkan sebesar 17,46 persen, subak tengah dinaikan 13,37 persen, dan subak hilir dinaikan 9,84 persen. ABSTRACT Availability of irrigation water can be influenced by the discharge of river water that drops in the dry season, loss of water in irrigation channels and evaporation. Thus, austerity measures need to be made such as a system of turns in irrigation water and balanced in the attribution of irrigation water on each subak. Research was conducted to determine the percentage of irrigation water storage present in a subak and the proportion of irrigation water at a time of lack of water availability. The acquisition of primary data is done by interviewing, observation, and measurement methods while secondary data is obtained from BMKG Region III Denpasar. The data collected will then be analyzed to look for the percentage of storage that occurs during water shortages and the balanced of irrigation water distribution. The results showed the method of turns was carried out when the discharge of available water could not meet the needs of irrigation water. The turns method occurs in the middle and upper subak from April to May. The method of turns is carried out by lowering the amount of irrigation water needs and providing irrigation water according to the discharge available with a time span every two days. The upstream subak does not have any savings because the rotating process is not running, irrigation water savings in the central subak averaged 28,3 percent and downstream subak by 24 percent. Water rotational method can be used when there is a shortage of irrigation water, therefor water needs can be met by the discharge of available water. To achieve the proportional irrigation water supply in April to May, the upper subak of irrigation water was lowered by 17,46 percent, the central subak was increased by 13,37 percent, and the downstream subak was increased by 9,84.
