Judul: Pre-Design Study of Coconut Shell-Based Product Processing Industy into Charcoal, Briquettes Charcoal and Activated Charcoal
Abstrak: Pemanfaatan tempurung kelapa menjadi produk arang, briket arang, dan arang aktif merupakan usaha prospektif dalam upaya memberikan nilai tambah terhadap komoditas kelapa Indonesia. Tujuan dari penelitian ini adalah mengkaji potensi tempurung kelapa, mengetahui potensi pasar impor dan ekspor, mengkaji kelayakan perancangan usaha berbasis tempurung kelapa berdasarkan aspek finansial, serta merancang usaha berbasis tempurung kelapa. Ruang lingkup penelitian meliputi analisis pasar dan pemasaran, teknis dan teknologi, manajemen dan organisasi, serta analisis finansial. Perancangan industri ditempatkan di provinsi Riau dengan total ketersediaan tempurung kelapa sebesar 0,04 juta ton/tahun dan membutuhkan 3% tempurung kelapa untuk di produksi menjadi arang, briket arang, dan arang aktif. Kapasitas produksi yang dirancang sebesar 1441,93 kg/hari arang; 320,62 kg/hari briket arang; dan 282,11 kg/hari arang aktif. Proses produksi arang akan menghasilkan limbah padat dan gas yang dapat dimanfaatkan menjadi produk turunan dari proses produksi arang. Berdasarkan analisis aspek finansial produk arang, briket arang, dan arang aktif menunjukkan nilai kelayakan secara finansial dengan nilai NPV, IRR, Net B/C, dan PBP yang memenuhi kriteria., Charcoal, briquette, and activated charcoal is a prospective product to provide added value to Indonesian coconut commodities. The purpose of this research is to study the potential of coconut shells, to find the potential import and export markets, to study the feasibility of designing a coconut shell based on financial aspect, to design a coconut shell business. The research scope includes market and marketing analysis, technical and technology, management and organization, and financial. The design is placed in Riau province with 0.04 million tons / year and requires 3% coconut shell to be produced . The designed production capacity is 1441.93 kg / day of charcoal; 320.62 kg / day charcoal briquettes; and 282.11 kg / day of activated charcoal. The charcoal production process will produce solid waste and gas which can be used as a byproduct of the charcoal production process. Based on the analysis of the financial aspects of the products of charcoal, charcoal briquettes, and activated charcoal, it shows the value of financial feasibility with NPV, IRR, Net B / C, and PBP values that meet the criteria.

Judul: Strategi Pemasaran Agroindustri Briket Arang Tempurung Kelapa
Abstrak: Indonesia merupakan salah satu negara penghasil kelapa terbesar di dunia dengan total produksi 18,3 juta ton per tahun. Ketersediaan tempurung kelapa yang melimpah ini dimanfaatkan untuk dijadikan briket arang tempurung kelapa sebagai bentuk energi terbarukan. Briket arang tempurung kelapa menguasai ekspor pasar Mesir, Nigeria, Brazil, Rusia, Ukraina, Moldova, hingga Turki. Penelitian ini bertujuan untuk mengetahui faktor internal dan eksternal yang memengaruhi strategi pemasaran produk agroindustri arang tempurung kelapa serta merumuskan formulasi pemasaran paling tepat untuk produk agroindustri briket arang tempurung kelapa. Penelitian ini menggunakan SWOT, matriks IFE dan EFE, matriks IE, matriks SWOT, serta matriks QSP. Hasil penelitian menunjukkan bahwa dari sisi internal, kekuatan (strength) yang dimiliki industri briket arang tempurung kelapa indonesia memiliki bahan baku dan lahan yang melimpah, jumlah tenaga kerja yang melimpah, proses produksi tidak sulit serta pemasaran yang mudah melalui media digital. Kelemahan (weakness) yang dimiliki ialah permodalan terbatas, tingkat pendidikan pekerja relatif rendah dan infrastruktur yang kurang memadai. Sisi eksternal, peluang (opportunities) yang dimiliki ialah permintaan ekspor yang cenderung meningkat, belum banyak pesaing dalam negeri, adanya dukungan pemerintah dan potensi membuka lapangan kerja baru. Sedangkan ancaman (threat) yang dimiliki ialah adanya ekspor kelapa utuh sebagai bahan baku, persaingan dari negara lain dengan kualitas lebih baik serta kebijakan pemerintah yang berubah-ubah. Alternatif strategi pemasaran hasil dari penelitian ini ialah mengkatkan kualitas produk, meningkatkan kualitas SDM, melakukan revitalisasi perkebunan kelapa, melakukan pembenahan organisasi UMKM, memperluas jangkauan promosi, menjalin kemitraan dengan negara lain, dan memanfaatkan SDA yang tersedia untuk meningkatkan nilai tambah. Indonesia is one of the largest coconut-producing countries in the world with a total production of 18.3 million tons per year. The abundant availability of coconut shells is used to make coconut shell charcoal briquettes as a form of renewable energy. Coconut shell charcoal briquettes dominate the export markets of Egypt, Nigeria, Brazil, Russia, Ukraine, Moldova, to Turkey. This study aims to determine the internal and external factors that influence the marketing strategy of coconut shell charcoal agro-industrial products and to formulate the most appropriate marketing formulation for coconut shell charcoal briquette agroindustrial products. This study uses SWOT, IFE and EFE matrices, IE matrix, SWOT matrix, and QSP matrix. The results showed that from the internal side, the strength of the Indonesian coconut shell charcoal briquette industry has abundant raw materials and land, an abundant number of workers, the production process is not difficult and marketing is easy through digital media. Weaknesses are limited capital, relatively low level of education of workers, and inadequate infrastructure. On the external side, the opportunities that are owned are export demand which tends to increase, there are not many domestic competitors, government support, and the potential to open new jobs. Meanwhile, the threats they have are the export of whole coconuts as raw materials, competition from other countries with better quality, and changing government policies. Alternative marketing strategies as a result of this research are improving product quality, improving the quality of human resources, revitalizing coconut plantations, reforming micro, small and medium enterprises organizations, expanding promotional reach, establishing partnerships with other countries, and utilizing available natural resources to increase productivity. value-added.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
