Abstract

This study was aimed at analyzing risk factors of nutritional anemia among new students of Bogor Agricultural University (IPB). A logistic regression model for 1907 new students’ record data matched with health record data was selected and applied on anemia risk factors analysis. The result showed that 10.9% and 21.4% of the students were suffering from nutritional anemia and proteinuria respectively. The risk factors of nutritional anemia among the new students of IPB are sex, age, family income and proteinuria status. The nutritional anemia risk is higher among female students (OR = 1.36); among younger age (age < 18 year); among students from low income family (OR = 1.70); and students suffered from proteinuria (OR = 1.49). This implies that the regular monitoring and controlling of both anemia and proteinuria among the students by Polyclinic of IPB are urgently required.   Keywords: risk factors, nutritional anemia, proteinuria

Abstract

This research was aimed to examine the perception of vegetable farmers on land conservation and investigating the impact of their perception and behavior toward land conservation on production. This research was conducted in Rejang Lebong District. On this research one hundred fifteen of respondents were selected as sample. Data collected by using stratified random sampling technique based on their land slope. Analytical descriptive method and double log models were used to analyze data which gathered from face to face interview guided by questionnaire. The result of the research showed that vegetable farmers had positive perception on land conservation. Their positive perception were reflected by their action in conserving their land, whether by bench terrace development or growing cover trees. The research also found that all variables included in the model had an expected sign, i.e., positive, except for cover trees growing and seed application that had negative sign. However, not all of these variables were different from zero. Only the cost of terrace development variable, fertilizer usage, land area, education, and farmer motivation to conserve their land had significant factors in influencing vegetable production, while farmers perception were not influenced.

Abstract

Sistem Pakar Penentuan Metode Statistika pada Peubah Tunggal dikembangkan untuk membantu pengguna dalam menentukan metode statistika yang sesuai untuk diterapkan dalam penelitiannya. Aspek keahlian dalam ilmu statistika menjadi alasan utama dipilihnya pengembangan sistem pakar dibandingkan dengan pengembangan perangkat lunak biasa. Adapun tahapan-tahapan yang dilakukan meliputi analisis dan identifikasi faktor-faktor yang mendasari pemilihan metode statistika, merancang model penentuan metode statistika dari faktor-faktor yang didapat, dan mengimplementasikan model penentuan tersebut menjadi Sistem Pakar Penentuan Metode Statistika. Dari segi substansi ilmu statistika, penelitian ini hanya dibatasi pada analisis data univariate saja. Dalam pengembangan sistem pakar ini, basis pengetahuan yang diperoleh dari tahap akuisisi pengetahuan direpresentasikan dengan metode kaidah produksi biasa (simple rule-based Method). Mekanisme inferensinya dibuat dengan strategi penalaran pasti (Exact Reasoning Mechanism) yang dikendalikan strategi pengendalian forward chaining dengan menetapkan nilai default sebagai solusi dari setiap kondisi. Adapun teknik penelusuran yang digunakan untuk mendukung implementasi dari strategi pengendalian tersebut adalah teknik penelusuran horizontal atau yang lebih dikenal dengan breadth-first search. Kata kunci: Sistem pakar, metode statistika, representasi pengetahuan, kaidah produksi, dan strategi penalaran pasti (Exact Reasoning Mechanism).

Abstract

Penambahan lapis perkerasan diatas lapis perkerasan lama (overlay) sebagai tindakan peremajaan lapis perkerasan dinilai kurang efektif karena hal tersebut dapat merusak lapisan pondasi dibawahnya serta memerlukan dana yang tidak sedikit. Diperlukan inovasi dalam pemeliharaan jalan yang ekonomis, efektif, dan ramah lingkungan. Recycling (daur ulang) merupakan metode yang dapat menjadi alternatif untuk permasalahan tersebut.  Pada penelitian ini menggunakan pencampuran perkerasan jalan dengan metode cold mix. Dalam metode cold mix diperlukan  bahan peremaja agar aspal yang terkadung didalamnya dapat diguanakan kembali. Pada campuran aspal daur ulang ini digunakan peremaja berupa oli bekas dan solar sebagai bahan peremjanya dengan perbandingan 0 : 100, 25 : 75, 50 : 50, 75 : 25, dan 100 : 0, kadar peremaja yang digunakan 2%, 4%, 6%, 8% dan 10% dan kadar asbuton yang digunakan adalah 3%, 6%, 9%, dan 12% dengan waktu pereman selam 4 hari. Dari penelitian ini menghasilkan kadar peremaja optimum pada kadar 2,93 %  proporsi peremajanya pada komposisi 75 : 25 ( oli bekas : solar ) dengan hasil nilai stabilitas maksimumnya 236,17 kg. Namun nilai stabilitas rata – rata dari komposisi peremaja 75 : 25 mengalami penurunan nilai stabilitas 81,93 % dari hasil core drill. Sehingga benda uji pada penelitian ini tidak memenuhi kriteria stabilitas untuk lalu lintas berat yaitu 800 kg. Namun, beberapa dari nilai stabilitas benda uji masuk kriteria untuk LATASIR yaitu 200 kg. Hal ini dapat dikatakan bahwa penelitian ini dapat dijadikan alternatif sebagai pengganti LATASIR.
