Abstract

The solution to going out from nature fuel crisis, Indonesian government has decided policy of development and utilization of biofuel. There are four patterns of biofuel development, that are: Activity of Village People Pattern, Micro and Middle Labours Pattern, Development by Industry, and Commercial Development by Large Estate Crops. Resources of energy alternative development of biofuel in national mainly from: palm oil, Jastropha curcas, Cassava and Sugar cane. Biofuel from coconut oil has a good potential and prospect in coastal areas, because the coconut palms are be there, where are copra price is low in that place, contrary the price of nature fuel is usually very expensive, and sometime not available. And the, most of coconut farmers has duplicated job as fisherman, and they need fuel for their motorboat for fishing or local transportation. Then usually, the electric is not available or limited in that areas, therefore biofuel could be used for genset, processing engine, or household industries. Thus, all of these activities which are relating to each other will be open the new labour in the villages level or isolated islands. The ICOPRI and Bandung Technology Institute have succed to produce the Coco-Biodiesel Processing Unit, which has a 100 liters capacity.   RINGKASAN Untuk mengatasi masalah krisis bahan bakar minyak (BBM), maka pemerintah telah menetapkan kebijakan pengembangan dan pemanfaatan Bahan Bakar Nabati (BBN). Pola pengembangan BBN dikemukakan ada empat, yaitu: Pola Kegiatan Rakyat Desa, Pola Usaha Mikro Kecil dan Menengah, Pengembangan oleh Perusahaan-Perusahaan Besar, dan Pengembangan Komersial oleh Perkebunan Besar. Sumber pengembangan energi alternatif dari BBN secara nasional adalah kelapa sawit, jarak pagar, singkong dan tetes tebu. BBN dari minyak kelapa memiliki potensi dan prospek yang baik bagi daerah-daerah yang sudah ada tanaman kelapa, yang letaknya terpencil, harga kopra sangat murah, sebaliknya harga BBM sangat mahal, dan sering tidak tersedia. Disamping itu sebagian besar petani kelapa, merangkap pekerjaan sebagai nelayan yang sangat membutuhkan bahan bakar untuk mesin perahunya ke laut, ataupun transportasi lokal. Listrik juga sering belum tersedia atau terbatas, sehingga BBN ini dapat dimanfaatkan untuk mesin genset, menggerakan alat-alat pengolahan tingkat desa, maupun industri rumah tangga. Dengan demikian, semua kegiatan yang saling terkait ini akan membuka lapangan kerja baru di pedesaan/pulau-pulau terpencil. Balitka yang bekerjasama dengan ITB telah berhasil merakit alat pengolahan Coco-Biodiesel dengan kapasitas olah sekitar 100 liter per hari.

Abstract

Identification of Phytophthora Isolates from Coconut Origin Wite Amplification Fragment Length Polymorphic (AFLP)Coconut Bud rot and nutfall caused by  fungus are the major anddangerous diseases of coconut palm. Nutfall of nuts and death of the palms leading to the reduction of coconut production are some of the consequences of the diseases. Morphologically identification of the causal agents is very limited and need certain skill. Molecular analysis is a good method to accurately identify characterize the disease causing pathogens especially Phytophthora originated from coconut palm. AFLP is one the accurate reproducible methods providing uniformnity results. The research aimed to identify and characterize Phytophthora isolate causing but rot a nutfall diseases. A total of 14 isolates was tested by its AFLP and then by AFLP with specific primers. The identification results showed that the 14 tested isolates with ITS1/ITS4 had band profile on the size of 900 base pairs (bp) which is a specific band profile for P. Palmivora. Of the 16 combinations specific primer of AFLP, indicated primers eg E, H, and Q gave accurate and homolog results that is good for AFLP analysis. AFLP analyses for 14 isolates of  gave accurate results of the band diversity.

Abstract

AbstrakProses penggorengan akan menyebabkan perubahan mutu minyak akibat reaksi hidrolisis, oksidasi dan proses termal. Penelitian ini bertujuan untuk mengetahui perubahan mutu  minyak kelapa dan minyak sawit selama penggorengan. Minyak kelapa dan minyak sawit masing-masing digunakan untuk menggoreng kentang pada suhu 170°C selama 15 menit. Minyak tersebut digunakan untuk 3 kali penggorengan. Pada akhir penggorengan dilakukan pengambilan sampel minyak untuk dievaluasi kadar air, kadar asam lemak bebas, bilangan peroksida dan bilangan TBA (Tiobarbituric acid). Hasil penelitian menunjukkan bahwa sebelum penggorengan minyak kelapa dan minyak sawit memiliki kadar air yang hampir sama, tetapi kadar asam lemak bebas, angka peroksida dan TBA minyak kelapa lebih rendah dibanding minyak sawit. Selama penggorengan minyak kelapa dan minyak sawit menunjukkan pola perubahan kadar air yang hampir sama. Pada 1 kali dan 2 kali penggorengan kadar asam lemak bebas, angka peroksida dan angka TBA minyak kelapa dan minyak sawit cenderung berfluktuasi. Pada 3 kali penggorengan minyak kelapa memiliki kadar asam lemak bebas,  angka  peroksida  dan  angka  TBA  yang  lebih  rendah  dibandingkan  minyak  sawit.  Hasil  yang  diperoleh menunjukkan   bahwa   minyak   kelapa  lebih   stabil   terhadap   reaksi   oksidasi   dibanding   minyak   sawit   selama penggorengan. Pattern of Coconut Oil and Palm Oil Quality During FryingABSTRACT Frying was a process which affected the quality of oil due to hydrolysis, oxidation and thermal reactions. The aim of the research was to study the quality pattern of coconut oil and palm oil quality during frying. The oils were utilized to fry french fries at 170°C for 15 minutes and then used in frying process for 3 times. Samples of oil were taken at the end of each frying period and analyzed for its moisture, free fatty acid, peroxide and TBA (tiobarbituric acid) values. The results showed that, coconut oil and palm oil having similary moisture content before and during frying. Otherwise free fatty acid, peroxide and TBA values at coconut oil lower then palm oil. During 1 and 2 times of frying period these two oils showed fluctuation in free fatty acid, peroxide and TBA values. During 3 times of frying, coconut oil contained free fatty acid, peroxide and TBA value lower than palm oi. Thus, we consider that coconut oil was more stable to oxidation compared to palm oil during frying

Abstract

Informasi tentang sistem penyerbukan pada suatu tanaman sangat penting dalam persilangan untuk menghasilkan varietas unggul. Pada tanaman pinang, agens penyerbuk masih belum pasti; ada yang menyatakan dilakukan melalui angin atau serangga. Tujuan penelitian adalah mengidentifikasi agens penyerbuk pada tanaman pinang. Penelitian dilakukan pada koleksi dua varietas pinang, yaitu Mongkonai dan Huntu di Kebun Percobaan Kayuwatu, Manado. Kegiatan mulai dilakukan pada awal musim penghujan yaitu bulan September sampai bulan Oktober 2013. Jumlah sampel tanaman pinang sebanyak 12 pohon setiap aksesi yang berumur 10 tahun. Identifikasi agens penyerbuk dilakukan dengan dua cara, yaitu pengamatan kunjungan serangga pada tandan bunga pinang dan perangkap serbuk sari menggunakan media agar yang diletakkan di bawah malai bunga betina. Hasil penelitian menunjukkan kunjungan serangga penyerbuk pada bunga pinang sangat sedikit (8 sampai 13 jenis dan rata-rata jumlah serangga antara 0,2-261,8 serangga per pohon) dibanding dengan kunjungan serangga pada bunga kelapa (14 jenis dengan rata-rata jumlah antara 0,2-901 serangga per pohon). Selama masa anthesis bunga betina, tidak terjadi kunjungan serangga hal ini disebabkan bunga betina pinang tidak menghasilkan nektar. Jumlah polen yang terperangkap dalam media yang pemasangannya selama 24 jam hanya berkisar antara 4-6 polen pada posisi media tegak, sedangkan media yang dipasang tertelungkup polen yang terperangkap sedikit sekali, yaitu hanya 1-2 polen. Ini menggambarkan sekalipun posisi bunga betina tertelungkup serbuk sari masih bisa diserbuki oleh angin. Jumlah polen yang terperangkap selama 144 jam (hari ke enam) bertambah antara 144-174 polen untuk pemasangan media perangkap dengan posisi tegak dan 54-82 polen untuk pemasangan media dengan posisi tertelungkup. Hasil penelitian menunjukkan bahwa agens penyerbuk pada tanaman pinang adalah angin. Bunga pinang tidak disukai oleh serangga penyerbuk karena jumlah serbuk sari yang sedikit dan tidak menghasilkan nektar.Kata kunci: Pinang, agens polinasi, serangga penyerbuk, angin, serbuk sari, bunga betina. ABSTRACTIdentification of Pollination Agen on Arecanut (Areca catechu L.)Information about pollination system on a crop is very important in hybridization to produce superior varieties. In arenut crop, pollinators agens is still uncertain; there are states carried by wind or insects. The purpose of the study is to identify the agents of pollinators on arecanut.The study was conducted on two varieties of arecanut collection, namely Mongkonai and Huntu at the Kayuwatu Experiment Garden, Manado. Activity began in the early rainy season is September to October 2013. The number of samples as many as 12 tree for each accession of 10 years old. Identification of agents pollinators done in two ways, namely observation of insects visit the flower cluster nut and pollen traps using media that is put under the female flower bunches.The results showed pollinating insects visit the flower of arecanut very little (8 to 13 types and number of insects between 0,2-261,8 insects per palm) compared with insects visit the flowers of coconut (14 species with a number between 0,2-901 insects per palm). During the period of female flower anthesis, no insects visit, this occurs due to the female flowers do not produce nectar. This illustrates the female flowers with down position at bunches, can still be pollinated by wind. Total pollen trapped in the installation media for 24 hours only range between 4-6 pollen on media vertical position, while media with headlong position pollen trapped that is only 1-2.Total pollen trapped for 144 hours (six days) increased between 144-174 pollen traps for the installation media to the vertical position and 54-82 pollen trapped for installation media with headlong position. The research showed that the pollinating agent in arecanut is the wind. Arecanut flowers are not favored by insect pollinators for pollen counts are few and do not produce nectar.Keywords: Arecanut, pollination agents, insect pollinators, wind, pollen grain, female flower.
