Pengembangan Perkebunan Inti Rakyat (PIR) Kelapa Sawit yang Berdayasaing di Kabupaten Pasaman Barat

Pengembangan sub-sektor perkebunan diharapkan mendorong pertumbuhan, pemerataan, dinamika ekonomi dan meningkatkan kesejahteraan masyarakat dipedesaan khususnya perkebunan kelapa sawit. Upaya yang dilakukan dengan mensinergikan antara perusahan perkebunan negara, perusahaan perkebunan swasta sebagai inti dan perkebunan rakyat sebagai plasma dalam Pola Perkebunan Inti Rakyat (PIR). Efisiensi perkebunan rakyat terjadi jika tingkat penggunaan sumber daya dalam suatu proses produksinya semakin sedikit. Penelitian ini bertujuan untuk mengukur keuntungan Aglomerasi Perkebunan Pola PIR kelapa sawit; menganalisis pengaruh keuntungan aglomerasi terhadap tingkat efisiensi dan daya saing dan merumuskan implikasi kebijakan terhadap pengembangan perkebunan Pola PIR di Kabupaten Pasaman Barat Penelitian dilaksanakan pada Bulan November sampai dengan Bulan Desember 2016. Lokasi penelitian di Kecamatan Sungai Aur Kabupaten Pasaman Barat Propinsi Sumatera Barat. Data yang digunakan dalam penelitian ini meliputi data primer dan data sekunder. Populasi pada penelitian ini adalah seluruh anggota kelompok pengelola perkebunan di Kecamatan Sungai Aua Pasaman Barat. Sampel diambil secara Proportionate Stratified Random Sampling, dengan menggunakan rumus slovin sampel untuk Petani PIR dan Non PIR masing-masing diambil sebanyak 99 orang. Data dan informasi diolah secara kuantitatif melalui pengukuran keuntungan Aglomerasi dan untuk melihat tingkat efisiensi dengan aglomerasi dengan analisis regresi linear berganda. Hasil pengukuran keuntungan aglomerasi (keuntungan Skala Besar (SE) keuntungan Lokalisasi (LE), dan keuntungan Urbanisasi (UE)) menunjukkan bahwa petani PIR masih lebih efisien dibandingkan dengan petani Non PIR. Hasil analisis linear berganda diperoleh formulasi regresi Y = 229,400 + 0,254 SE + 0,494 LE + 1,801 UE. Uji t menunjukkan secara parsial masing-masing variable berpengaruh secara signifikan terhadap efisiensi harga. Uji F pada model regresi dapat dikatakan bahwa SE, LE dan UE secara bersama-sama berpengaruh terhadap efisiensi harga. Dapat disimpulkan bahwa keuntungan aglomerasi yang terdapat dalam sistem perkebunan pola PIR ternyata mempengaruhi efisiensi harga yang selanjutnya menentukan daya saing produk kelapa sawit. Keuntungan skala besar, keuntungan lokalisasi dan keuntungan urbanisasi baik secara parsial maupun bersama mempengaruhi efisiensi harga secara signifikan. Penelitian ini menutup kelemahan penelitian terdahulu dengan melihat pengaruh keuntungan aglomerasi terhadap efisiensi dan daya saing. Penelitian ini menekankan pada pengaruh masing-masing komponen keuntungan aglomerasi terhadap efisiensi harga yang merupakan kekuatan daya saing usaha. Kata kunci: Keuntungan Aglomerasi, PIR, Efisiensi dan Daya sain

EFEK PEMBERIAN ORGANIK TITHONIA DAN PUPUK UREA TERHADAP RESPON PERTUMBUHAN BIBIT KELAPA SAWIT

Seedlings which look prima is a prerequisite for the success of oil palm cultivation. Besides, because of the factors in the pre-nursery genetic, the provision of nutrients in early growth seedlings has an important role performance determine the appearance of the seedlings thoroughly. This study aims to determine the influence of the growth of oil palm seedlings at each concentration of organic fertilizer tithonia and fertilizer of urea for pre-nursery. The experiment was carried out from Oktober 2023 to April  2024 in the Experimental Garden of the Faculty of Science and Technology, the University of Labuhanbatu Rantauprapat with a height of 13 meters above sea level. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The experimental design used was a Randomized Block Design with a factorial pattern that is repeated three times. The first factor includes the dose of Organic Fertilizer Tithonia (ton/ha) comprising of three standards, namely T0 = 0 ton/ha, T1 = 10 ton/ha, T2 = 20 tons/ha and the second factor was fertilizer dosage Uera which consists of four levels, namely U0 = 0 kg/ha, U1 = 100 kg/ha, T2 = 200 kg/ha, U3 = 300 kg/ha. The experimental results show that there are significant interactions of organic fertilizer Tithonia with fertilizers urea on plant height (cm) and leaf area of oil palm seedlings (cm2). Treatment of organic fertilizer tithonia 20 tons/ha with fertilizer urea 300 kg/ha yield plant height and leaf area of oil palm seedlings the best for pre-nursery

Assessment the Role of Basic Science Courses in Dentistry Capability Based on Opinion of Dentistry Students of Babol Medical Science University

Curriculums need a correct cognition of students' requirements in order to train the qualified people. Current study is designed and conducted to assess the role of basic science courses on dentistry ability of Dentistry Students of Babol Medical Science University. This cross-sectional study is conducted on dentistry students studying in the last two semesters at Babol University of Medical Sciences admitted in 2007 and 2008 and by using a questionnaires 38 questions about 9 competencies of dentistry. The answers were classified into five grades from zero to four with scores including Not at all = 0, A little = 1, Somehow = 2, Very = 3, and Very much = 4. The required information was extracted from information recording forms and was calculated and analyzed by using SPSs.V.18 software and in terms of frequency of answers, frequency percentage and average marks. Among 60 contestants (23 males and 37 females), the highest competency score was related to effective communication (% 63), using basic sciences in direction of patient, diagnosis, treatment and prevention (%61) and solving the problem (%61). The lowest score of competency is related respectively to the community and social grounds for healthcare (%42) and preliminary clinical qualifications (%45).As commented by students, basic science courses are not effective on training of professional dentists. Thus some changes are needed to conduct on basic science curriculums to train dentists with high competency

The impact of farmer partnerships on arabica coffee farming in Simalungun Regency, North Sumatra Province, Indonesia

Coffee is one of Indonesia's main economic activities for foreign exchange. An increase in exports of 8.11%, and a decline in imports of 58% in 2019, opened up export opportunities and large domestic markets. The government has implemented efforts to improve coffee farmers' welfare, one of which is agricultural business partnerships that can solve smallholder problems in developing countries and expand subsistence or traditional agriculture to high production value and export-oriented. This research aimed to analyze (1) the factors influencing coffee farmers' participation in agricultural partnerships and (2) the impact of the agricultural partnership on coffee farmers' performance in Simalungun Regency, North Sumatra Province. The Propensity Score Matching (PSM) technique analyzed the partnership's influence on coffee farming and agricultural income, productivity, and prices.  The results showed that number of dependents  household members and land area influence farmers' partnership participation. Participation increases coffee farming and agricultural income, productivity, and prices

Design a methodology to model – reference control of first order delays system

Design a nonlinear controller for second order nonlinear uncertain dynamical systems is one of the most important challenging works. This research focuses on the design, and analysis of a model-reference sliding mode controller for first order delay system, in presence of uncertainties. In order to provide high performance nonlinear methodology, model-reference sliding mode controller is selected. Pure sliding mode controller can be used to control of partly known nonlinear dynamic parameters. Conversely, pure sliding mode controller is used in many applications; it has an important drawback namely; chattering phenomenon. To attenuation the chattering, new filter based high speed control technique is introduced. In this technique, two type derivative techniques are used to improve the rate of delay as well stability, robustness and chattering attenuation. This technique cased to improve the rate of delay compare with conventional PID controller and conventional sliding mode controller
