ABSTRAK Buah melon yang telah mengalami pengolahan minimal memiliki sifat mudah rusak (perishable) dengan masa simpan yang relative singkat. Penelitian ini bertujuan untuk mengatahui pengaruh pelapisan gel lidah buaya dengan campuran asam askorbat dan kalium sorbat terhadap susut bobot, pH dan organoleptik buah melon potong segar atau proses minimal. Penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri dari dua faktor perlakuan yaitu konsentrasi asam askorbat (0%, 1.5% dan 3%) dan kalium sorbat (0%, 0.2% dan 0.4%). Percobaan ini diulang sebanyak tiga kali dengan suhu penyimpanan 5±2?C. Hasil penelitian menunjukkan asam askorbat dan kalium sorbat berpengaruh nyata terhadap nilai susut bobot, pH dan atribut organoleptik buah melon potong segar. Asam askorbat dan kalium sorbat mampu menghambat kehilangan bobot, mempertahankan nilai organoleptik dan menurunkan nilai pH sehingga aktivitas pertumbuhan jamur dan kapang terhambat pada buah potong tersebut. Gel lidah buaya dengan penambahan asam askorbat 3% dan kalium sorbat 0,2% merupakan perlakuan yang memberikan nilai atribut organoleptik terbaik selama penyimpanan. Kombinasi ini mampu mempertahankan nilai warna dan tekstur hingga hari ke 14 serta mempertahankan aroma hingga hari ke 10. ABSTRACT Melon fruit which is undergone a minimal process is easy to damage (perishable) with short shelf life.  This study aims to determine the effect of coating aloe vera gel with a mixture of ascorbic acid and potassium sorbate on weight loss, pH, and organoleptic of fresh-cut melons. This study using a completely randomized design (CRD consisted of two treatment factors, namely ascorbic acid (0%, 1.5%, and 3%) and potassium sorbate (0%, 0.2% and 0.4%)). The experiment was replicated three times with a storage temperature of 5 ± 2?C. The results showed that ascorbic acid and potassium sorbate significantly affected the weight loss, pH, and organoleptic values ??of fresh-cut melons. Ascorbic acid and potassium sorbate can inhibit weight loss, maintain organoleptic values ??, and reduce the pH value of fresh-cut melons so that the activity of fungal and mold growth is inhibited. Aloe vera gel with the addition of 3% ascorbic acid and 0.2% potassium sorbate was the treatment that gave the best organoleptic value during storage. This combination can maintain the value of color and texture up to day 14 and maintain aroma until day 10.

Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik.

Abstract Rhynchophorus palmarum (L.) (Coleoptera: Dryophthoridae) is an important pest in oil palm plantations, and its populations are monitored through rhynchophorol pheromone-baited traps. To optimize the release of rhynchophorol in high-density polyethylene diffusers, five calibers (2, 3, 4, 5, and 6) were evaluated. The experiment was conducted under a completely randomized design with 15 repetitions, recording daily weight loss of pheromones. Release rate of pheromone under laboratory conditions (30.2 ± 0.1°C; 70.8 ± 0.8% relative humidity [RH]) varied between 2.2 and 10.4 mg/day. Three diffusers with 2.4 ± 0.4, 3.6 ± 0.9, and 8.5 ± 1.3 mg/day of release rates, were selected for testing in three palm-growing zones. Adults of R. palmarum captured in traps with different diffusers were counted as well as pheromone weight loss. In two of three plantations, statistical differences were found in the capture of R. palmarum adults among the diffusers that presented different pheromone release rates (Eastern: F = 8.27; df = 2, 9; P = 0.0028; Central: F = 10.79; df = 2, 9; P = 0.0008; Southwestern F= 2.20; df = 2, 9; P= 0.1402). The diffuser with the release rate of 2.4 mg/day was selected because, after remaining 4 mo in the field, the traps with this diffuser registered catches statistically equal to those that had traps with newly installed diffusers. We concluded that the release rate of the pheromone of 2.4 mg/day is optimal for the capture of adults of R. palmarum during a period of 4 mo.

Biopore infiltration hole are hole made for run-off flow which if allowed to cause erosion and can remove the topsoil, causing soil fertility to be reduced. The use of biopori infiltration holes can be maximized by adding organic matters into the hope that in addition to absorbing water it can increase soil fertility. The liquid waste of tofu and meranti litter is an organic matters are used in this study, by adding organic matters to the biopori hole. This study aims to look at the effect of providing organic matters in the biopore hole derived from tofu and litter liquid waste on the value of pH, C-Organic, and post-mining CEC. This study was an experimental study in the field using a completely randomized design of one factor, namely organic matters with six levels, namely without organic matters and using 25 g, 50 g, 75 g, and 100 gr organic matters given to the biopori hole in incubation for one month later Soil samples taken were analyzed for pH, C-organic, and CEC. The results showed that the treatment only affected the soil's pH value. Organic material provided in the biopori hole is thought to have not completely decomposed, causing the soil around the biopori infiltration hole to remain acidic. The acidity of the soil is due to the gases produced during the decomposition process. Changes in soil pH ranged from 4.36 to 4.65 by administering 75g of organic matters from tofu liquid waste and meranti litter. This research is useful in post-mining land reclamation in increasing soil fertility, with the improvement of soil chemical properties such as pH will slowly improve the physical and biological properties of the soil so that it can be used as cultivation land.
