Ada 292 sekolah dasar yang terdapat di Surakarta baik sekolah dasar negeri maupun sekolah dasar swasta. Sekolah tersebut tidak hanya didominasi oleh siswa yang berasal dari kota Surakarta saja, namun juga terdapat siswa dari luar kota Surakarta. Kondisi itulah yang memunculkan adanya bisnis layanan antar jemput bagi siswa. Salah satu faktor yang menjadi pertimbangan dalam bisnis kendaraan antar jemput adalah biaya. Beberapa pihak pengelola mengalami kesulitan dalam menentukan besarnya biaya layanan antar jemput dikarenakan penentuan biaya yang sudah ada hanya menggunakan jarak terdekat dan terjauh. Oleh karena itu, untuk mengetahui kelayakan bisnis dan besarnya potensi layanan antar jemput perlu diadakan evaluasi. Evaluasi pada penelitian ini menggunakan studi kelayakan bisnis yaitu dengan menggunakan payback period, net present value dan IRR. Tahap awal evaluasi potensi bisnis ini adalah mengidentifikasi jumlah siswa yang menggunakan layanan antar jemput dan biaya layanan antar jemput. Tahap kedua adalah memetakan sebaran siswa layanan antar jemput dengan menggunakan GIS untuk mengetahui estimasi jarak tempuh. Kemudian, menghitung biaya per km sebagai dasar perhitungan kelayakan bisnis layanan antar jemput. Tahap terakhir adalah mengevaluasi kelayakan bisnis. Hasil evaluasi kelayakan bisnis layanan antar jemput berdasarkan studi kelayakan investasi diperoleh hasil untuk payback period sebesar 3 tahun 8 bulan lebih rendah dibandingkan ketentuan umur ekonomis 8 tahun. Net Present Value sebesar Rp 71.155.644 lebih dari 0. Nilai IRR sebesar 41% lebih tinggi dibandingkan suku bunga bank 12,38%

Instalasi pengolahan air limbah (IPAL) diperlukan oleh industri tahu-tempe agar bisa mengurangi dampak lingkungan. Bagi industri-industri kecil dan menengah (IKM) tahu-tempe, instalasi tersebut lebih baik dibangun secara komunal untuk mengoptimalkan biaya pembuatan dan kapasitas. Permasalahan yang kemudian timbul adalah berapa jumlah kebutuhan IPAL dan di lokasi mana saja instalasi tersebut dibangun. Permasalahan inilah yang dihadapi oleh Pemerintah Kota Surakarta ketika merencanakan pembangunan beberapa IPAL di kawasan industri tahu-tempe Mojosongo, Kota Surakarta. Oleh karena itu, penelitian ini bertujuan memilih alternatif lokasi IPAL komunal dengan mempertimbangkan sejumlah kriteria objektif dan subjektif. Kriteria-kriteria tersebut dikelompokkan menjadi kriteria teknis, administratif dan kriteria sosial. Metode fuzzy TOPSIS digunakan dalam memilih alternatif lokasi yang optimal. Hasil penelitian memberikan rekomendasi bagi pemerintah Kota Surakarta untuk membangun empat titik lokasi IPAL komunal yang dapat digunakan untuk empat puluh satu IKM tahu-tempe di kawasan Mojosongo, Kota Surakarta

Oil palm smallholders require knowledge of fertilization because the fertilization is an influential factor in the productivity of fresh fruit bunches. On the other hand, the oil palm smallholders generally don’t have fertilizer expertise and they face a difficulty in determining good fertilization (good in type, dosage, time and manner) based on various literatures. Therefore, a simple application that can provide recommendations for palm oil fertilization is developed. The recommendations are based on expert knowledge that have been written in various literatures. Like an expert system, the application is designed by compiling knowledge base, constructing an inference engine and creating a prototype. The knowledge bases, that are facts and rules, are prepared using rule-based reasoning approach, the inference engine is compiled using forward chaining methods and the prototype is made using a visual basic application in a spreadsheet application. The application design uses facts of plant varieties, phases or age of plants, soil types, nutrient deficiency in soil and plants, rainfall, fertilizer content, and nutrient properties (synergies or antagonist) on fertilizers. The Applications made capable of providing fertilization recommendations by conducting forward chaining based on data-given facts and rules that have been made on the knowledge base.
