Judul: Instrumen Pembayaran Jasa Lingkungan dalam Mendukung Penataan Ruang DAS Ciliwung
Abstrak: Daerah Aliran Sungai (DAS) Ciliwung merupakan DAS yang memiliki nilai sangat strategis karena melintasi Provinsi Jawa Barat dan DKI Jakarta. Salah satu dampak pembangunan yang sangat pesat di DAS Ciliwung adalah bencana banjir akibat kurangnya daerah resapan air. Hingga saat ini kebijakan pengendalian banjir lebih didominasi oleh kebijakan struktural (fisik). Kebijakan non-struktural diperlukan untuk perbaikan dalam jangka panjang. Penataan ruang merupakan salah satu pendekatan non struktural dalam pengelolaan banjir, namun implementasinya seringkali tidak sejalan karena pola penggunaan lahan yang bernilai ekonomi tinggi menjadi pilihan masyarakat. Pembayaran jasa lingkungan atau Payment for Environmental Services (PES) merupakan mekanisme yang dapat memberikan insentif kepada masyarakat sehingga konservasi menjadi menarik bagi pemilik lahan. Implementasi PES di Indonesia secara formal didasarkan pada UU PPLH Nomor 32 Tahun 2009, namun definisi operasional dalam bentuk peraturan di bawahnya belum ada. Penelitian ini bertujuan (1) menganalisis implementasi PES, yang terdiri dari penentuan penyedia jasa lingkungan, besaran pembayaran jasa lingkungan dan mekanisme implementasi PES (2) menganalisis alokasi ruang yang optimal dengan melibatkan besaran PES, dan (3) menganalisis mekanisme kelembagaan PES untuk mendukung penataan ruang di DAS Ciliwung. Metode yang digunakan dalam penelitian ini terdiri dari beberapa metode. Penyedia jasa lingkungan menggunakan pendekatan spasial. Penentuan besaran jasa lingkungan menggunakan Contingent Valuation Method (CVM) berdasarkan Willingness to Pay (WTP). Mekanisme implementasi PES menggunakan pendekatan Ostrom Institutional Analysis Development (IAD). Analisis kontribusi PES dalam model tata ruang optimal menggunakan pendekatan spasial dan dinamik. Analisis spasial dilakukan untuk mengetahui pola perubahan ruang dan arah perubahan dari pola ruang DAS Ciliwung Tahun 1989, 2000, 2010 dan 2015. Analisis dinamik dilakukan dengan menggunakan nilai besaran PES dan pola dan arah perubahan ruang hasil analisis sebelumnya. Mekanisme kelembagaan PES untuk mendukung penataan ruang di DAS Ciliwung dianalisis menggunakan IAD Ostrom...dst

Judul: Peran pembayaran jasa lingkungan (PJL) hutan terhadap sifat hidrologi lahan di DAS Cidanau, Banten
Abstrak: Payment for Environmental Services (PES) in Cidanau watershed is the payment for environmental services of Forest Ecosystem to control the water yield in Cidanau watershed. This PES is driven by issue of water yield decreasing, suggested due to forest encroachment of Rawa Danau. The role of PES for water yield control is approached through its role for the soil hydraulic properties. The research aim to analyze the difference of soil hydraulic properties managed with and without PES incentives. The research includes analysis of land use changes, infiltration rate and soil hydraulic properties of land with and without PES, and simulation of water flow as the response of rainfall. Implementation of PES in Cidanau watershed is able to maintain the good condition of forest. Soil hydraulic properties of land with PES is relatively better. The infiltration rate of land with PES is higher than without PES. Gravitational and available water is higher in land of without PES whereas the soil hydraulic condactivity is higher in land of with PES. Kostiakov and Horton models both are able to predict the rate of infiltration. Kostiakov is better than Horton model relatively. Log Normal Kosugi model was able to predict a soil-water retension curve and unsaturated hydraulic conductivity. One dimensional vertical flow simulation shown the higher flow in land with PES than without PES.

Judul: Kandungan Kolesterol dan Vitamin A Ayam Arab yang Diberi Jamu Ternak Melalui Air Minum
Abstrak: Egg as one source of protein needed by the body contains high amount of essential amino acids, however in reality there is a constraint factor in consuming the eggs which is the high level cholesterol in an egg. Nowadays the cholesterol content of eggs is feared by most of the public in relation to its effect. Excess cholesterol can cause health problems, but on the other hand the yolks contain vitamin A which is good for the body. This research was aimed to study the cholesterol and vitamin A content of Arab chicken egg yolks with addition of herbs through drinking water it is expected to reduce the cholesterol level and increase the amount of vitamin A in egg yolks. This experiment was conducted in poultry house in block C of Animal Science Faculty, Bogor Agricultural Institute, it lasted from June to August 2011. Chicken used in this study was 48 arab hens by age 19 weeks. Research procedures include the preparation of cages and equipment, maintenance and provisions of herbal medicine. The design used in this study was a completely randomized design (CRD). The content of cholesterol during 5 weeks of herbal medicine with level of 5 ml per head and 10 ml per head was 535.28 mg/100 g up to 563.51 mg/ 100 g. The addition of herbal medicine for 3 consecutive days (per week) are mixed in hens drinking. The level differences does not affect the content of cholesterol in egg yolk, but the existence of different herbal medicine addition level provides different amount of vitamin A. The content of vitamin A in egg yolks for a treatment P0 (without herbs) amounted to 596.787 μg/ 100 g, P1 (herbs 5 ml/head/day) : 700.034 μg/ 100 g and P2 (10 ml/head/day) : 800.962 μg/ 100 g.
