Judul: Pertumbuhan Vegetatif Tanaman Cabai Merah (Capsicum  annuum L.) dengan Pemberian Pupuk Kandang Kotoran Ayam di  Lahan Gambut
Abstrak: Budidaya tanaman cabai merah (Capsicum annuum L.) mempunyai beberapa kendala jika budidaya dilakukan di tanah gambut, seperti kondisi tanah yang asam dan ketersediaan unsur hara yang rendah. Salah satu cara untuk mengatasi hal tersebut adalah dengan memberikan pupuk kandang. Penelitian tentang pengaruh pupuk kandang terhadap pertumbuhan tanaman cabai sudah banyak dilakukan. Akan tetapi, penelitian tentang pengaruh pupuk kandang khususnya dari kotoran ayam terhadap pertumbuhan tanaman cabai di tanah gambut belum banyak dilakukan. Penelitian ini bertujuan menganalisis pengaruh pupuk kandang kotoran ayam terhadap pertumbuhan vegetatif tanaman cabai merah (Capsicum annuum L.) di lahan gambut. Rancangan penelitian yang digunakan adalah rancangan acak kelompok dengan 3 perlakuan dan masing-masing perlakuan dilakukan 10 ulangan. Perlakuan yang diberikan yaitu P1 (kontrol), P2 (pupuk kandang kotoran ayam), dan P3 (pupuk kandang kotoran ayam dan pupuk TSP). Pengamatan dilakukan selama 28 hari setelah tanam (HST) setelah tanaman dipindahkan ke bedengan. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang kotoran ayam berpengaruh nyata terhadap pertumbuhan vegetatif tanaman cabai merah di lahan gambut di Kecamatan Bengkalis, Kabupaten. Bengkalis, Riau. Kata kunci: Cabai merah, pertumbuhan vegetatif, pupuk kandang ayam, tanah gambut

Judul: Pemanfaatan Kitosan dan Media Organik untuk Pertumbuhan dan Produktivitas Tanaman Cabai Merah (Capsicum annum L.) di Screenhouse
Abstrak: Indonesian farmer incapable of fulfilling chili demands due to low productivity. Chitosan are capable of increasing productivity and inducing disease resistance against various pathogens. This research conducted to meet the best concentration of chitosan when combined with soil and manure as fertilizer. The combinations of soil and manure were 70%:30% (P1), 50%:50% (P2), and 30%:70% (P3), and the plants were sprayed with variation of chitosan concentration (0, 2, 4, 6, and 8 ml/L). The measured parameters were plant heights, number of leaves, stem diameters, number of flowers and fruits, and fruit weights. Only number of flowers and fruits, and fruit weights showed significant results based on Duncan test 5%. The combination of P2 medium with 2 ml/L of chitosan was the best combination for increasing flowers in week 13th (10) and fruit in week 15th (24.33) significantly. The combination of P2 medium with 4 ml/L of chitosan was the best combination for increasing fruit weights in week 18th (75.67 gr) significantly. Chitosan can also increase plant recovery time when damaged by disease.

Abstrak: At an emergency unit of a hospital are generally posted several physicians for 24 hours for each and every day. The management unit of an emergency room usually has to deal with schedulling problem of physicians with time constraint of availability. This scheduling problem can be modeled as an integer linear programming (ILP) problem. ILP is an optimization problem with linear objective function, linear constraints, and integer variables. Scheduling problem is formulated in an optimization model, where the objective function is to minimize the operational cost of emergency room with the following constraints: (i) the time availability of physicians, (ii) the balanced work load for every physicians, (iii) holiday and dayoff determination of each physician. This paper discusses the schedulling of an emergency room’s physicians problem in the form of ILP, with a case study at Emergency Unit of Cipto Mangunkusumo Hospital (RSCM), Jakarta. The model is solved using Lingo 8.0 software. The solution obtained using ILP scheduling method is found to be more balanced than the corresponding solution using conventional method.
