Judul: The Guidance for Coastal Region Development of Rembang Regency Based on Salt Commodities
Abstrak: Garam adalah komoditas strategis yang memiliki kegunaan penting bagi manusia, terutama untuk memenuhi kebutuhan rumah tangga dan industri. Kebutuhan garam Indonesia saat ini belum dapat dipenuhi oleh produksi dalam negeri, bahkan separuh dari kebutuhan garam tersebut dipenuhi dari impor garam. Kabupaten Rembang sebagai salah satu sentra produksi garam nasional memiliki potensi untuk ditingkatkan produksi garamnya. Lokasi penelitian ini difokuskan di wilayah pesisir Kabupaten Rembang dengan tujuan sebagai berikut: 1) menganalisis kesesuaian lahan untuk tambak garam, 2) menganalisis kelayakan usaha tambak garam, 3) menganalisis keselarasan lahan potensial tambak garam terhadap RTRW Kabupaten Rembang, 4) menganalisis implikasi sosial dan ekonomi dari pemanfaatan lahan potensial tambak garam di pesisir Kabupaten Rembang untuk produksi garam, dan 5) menyusun arahan pengembangan wilayah pesisir Kabupaten Rembang berbasis komoditas garam. Penentuan lokasi yang sesuai untuk pengembangan tambak garam perlu mempertimbangkan hasil evaluasi kesesuaian lahan dan kelayakan usaha. Kelayakan usaha dievaluasi berdasarkan keuntungan atau kerugian yang akan didapatkan jika lahan tersebut dimanfaatkan untuk usaha produksi garam. Peta kesesuaian lahan hasil analisis selanjutnya di-overlay dengan peta penggunaan lahan dan peta RTRW Kabupaten Rembang 2011-2031 untuk mengetahui lokasi lahan pengembangan tambak garam yang selaras terhadap peruntukan kawasan. Berdasarkan hasil penelitian, lahan yang memiliki kategori kesesuaian lahan S1 luasnya adalah 10.325 hektar atau 28,45% dari luas seluruh lahan di pesisir Kabupaten Rembang, lahan S2 luasnya adalah 5.687 hektar atau 15,67%, lahan S3 luasnya adalah 2.471 hektar atau 6,81%, sedangkan lahan yang tidak sesuai untuk tambak garam (N) luasnya adalah 17.813 hektar atau 49,08%. Lahan yang tersedia untuk tambak garam luasnya adalah 3.560 hektar. Berdasarkan hasil analisis ekonomi diketahui bahwa lahan dengan kategori S1, S2, dan S3 dapat menghasilkan keuntungan jika dimanfaatkan untuk usaha produksi garam. Area lahan potensial untuk pengembangan tambak garam yang selaras terhadap RTRW luasnya adalah 2.484 hektar. Implikasi terhadap aspek sosial dan ekonomi atas pemanfaatan seluruh lahan potensial untuk tambak garam adalah terciptanya peluang kerja pergaraman sebanyak 5.894 orang dan diperolehnya potensial produksi garam sebesar Rp. 66,9 miliar per tahun yang sanggup memberikan kontribusi sebesar 0,26% terhadap total PDRB tahun 2025. Pengembangan wilayah pesisir Kabupaten Rembang diarahkan ke dalam 3 (tiga) kategori arahan, yaitu wilayah yang diarahkan untuk dipertahankan produktivitasnya seluas 1.366 hektar, wilayah yang diarahkan untuk ekstensifikasi lahan seluas 931 hektar, dan sisanya dengan luas sebesar 187 hektar diarahkan untuk intensifikasi lahan., Salt is a strategic commodity that has essential uses for humans to meet household and industrial needs. Domestic production cannot meet Indonesia's current salt needs, even half is completed from imported salt. Salt production in Rembang Regency as one of the national salt production centers can be increased. The location of this research is focused on the coastal region of Rembang Regency with the following objectives: 1) analyze the land suitability for salt ponds, 2) analyze the business feasibility of a salt pond, 3) analyze the alignment of potential land for salt ponds with the RTRW of Rembang Regency, 4) analyze the social and economic implications of utilizing the potential land of salt ponds on the Rembang Regency coast for salt production, and 5) arrange development direction of the coastal region of Rembang Regency of based on

Judul: Analisis Pendapatan Usaha Garam Rakyat Berdasarkan Status Lahan dan Penggunaan Zat Aditif (Studi Kasus: Desa Santing, Kecamatan Losarang, Kabupaten Indramayu)
Abstrak: Indonesia is a maritime country with a variety of marine and fishery resources of wealth. One that can be utilized is sea water as a raw material for producing salt. Although it has abundant marine wealth, Indonesia still remains a substantial importer of salt annually. Since 2006 – 2010, the Government of Indonesia imports amounted to 1.731.309 tons, 4, on average per year. Santing village is one of the largest salt manufacturer in Indramayu Regency, while Indramayu Regency is the largest salt producer in West Java. Therefore base on the potential of the area, Indramayu Regency is expected to optimize more the production of salt. Production propotionally compares to income, so the farmers have to increase the production of salt by optimizing the input that is used as a factor of production in order to improve their income. The additives substance named ramsol is used as additional inputs in producing salt by some farmers in the village of Santing and it is good to improve the quality and output of salt, from the results of interviews with 100 respondent, 62 respondents use additives as additional inputs to their salt production, and the rest, 38 respondents do not use additives. The factors that affect the production of salt are the number of windmills, land area, labor and additives. But in a season of 2011 salt farmers who use additives caan improve their salt production on average 85.053,76 kg per ha, while the farmers who do not use additives is only 71.903 .51 kg per ha. The analysis of people’s salt revenues is differed based on the status of the land and the use of additives. Status of land is divided into two categories, first the farmers’s production sharing land (penyakap) and the second is the farmers on the leased land. The highest income will be obtained by the farmers who use additives on their own land. The lowest income will be gained by the farmers whoo do not use additives and they produce on the production sharing land status.

Judul: Comparison of HIV Model with and without Time Delay
Abstrak: Acquired immunodeficiency syndrome (AIDS) is the reduction of the human immune system. AIDS is caused by human immunodeficiency virus (HIV). No medicine has been found for this desease until recently. An AIDS therapy is usually performed with highly active antiretroviral therapy, namely reverse transcriptase inhibitors, protease inhibitors and combination of both. Various models have been developed to explain the immune system of patients with AIDS, namely the HIV, response and the time delay model. This paper discusses the comparison between the dynamics of the HIV virus, the dynamic response of protease inhibitors and dynamics of time delay. The dynamics model of HIV is influenced by the level of white blood cells produced and the rate of its death. Dynamics of protease inhibitors on the response and the time delay model is influenced by the death rate of infected white blood cells and the failure rate of treatment.
