Abstract

Large scale exploitation of Jatropha curcas for biofuelproduction is restrained by low productivity henceeconomically not protable. One of the main constraintsis due to limited number of female owers in aninorescence which eventually develop into fruits thatbear seed. Investigation on oral biology andreproductive potential of the species had been carriedout, but seems to vary among sites. The research wasconducted to study reproductive success and thecompatibility among Indonesian Jatropha accessions.The research was set up in two experiments. The rstexperiment was conducted at the Jatropha seedorchard, Pakuwon, Sukabumi, West Java from April toJuly 2007 using four-year- old trees of accessions fromLampung, Banten, West Java, and Central Java. Thesecond experiment was conducted at LeuwikopoExperimental Station of Bogor Agricultural Universityfrom April to July 2008 using one-year-old trees ofaccessions from Lampung, Bengkulu, Palembang, andKediri. Flowers were obtained from controlled self andcross-pollinated as well as left for open-pollination. Theresult showed that reproductive success varied amongaccessions; the greatest success was 0.73 obtainedfrom aWest Java accession and the least was 0.53 fromBanten accession. The Jatropha accessions werecategorized as partially self-incompatible as indicatedby index of self-incompatibility (ISI) that ranged 0.93-0.99. Banten accession produced highly viable andvigorous seeds regardless of pollination methods;accessions of Central Java produced higher viabilityseeds when cross-pollinated within accession, whereasthose from West Java and Lampung produced higherviability seeds when self-pollinated.Keywords: accessions, Jatropha curcas, selfpollination,self-incompatibility, seedviability

Abstract

Karst ecosystem in Bogor is currently threatened by mining activities. Restoration of the disturbed karst areas is urgently required. Seed banks are considered as an important potential seed sources for restoration. This study was conducted to quantify the composition and species diversity of the aboveground vegetation and the seed bank. The study determined the correspondence between the seed bank with the aboveground vegetation in relation with ecosystem restoration. Twenty 6 m × 6 m vegetation plots were established. A total of sixty soil samples were taken from the study sites. The seed bank was studied using germination experiment. All plant species in the vegetation plots and seedlings growing from all soil samples were identified and the number was counted to determine the composition, index of diversity, and index of similarity. There were 80 species from 41 families found in the seed bank in Mt. Nyungcung, dominated by Clidemia hirta (Melastomataceae), whereas 50 species from 29 families found in Mt. Kapur with Cecropia peltata (Urticaceae) dominated the site. Diversity index of Mt. Nyungcung and Mt. Kapur seed banks were 2.09 ± 0.21 and 1.78 ± 0.47 respectively. The similarity index between seed bank and the aboveground vegetation in the two study sites were 32.86% and 27.66% respectively. Mt. Nyungcung seed bank was more diverse than Mt. Kapur. The similarity between the seed bank with the aboveground vegetation in the two study sites were low. Further assessment is needed to determine the role of the seed bank of Mt. Nyungcung and Mt. Kapur in the restoration of the ecosystems.

Abstract

Deteriorasi merupakan hal yang tidak dapat dihindari meski penyimpanan benih dilaksanakan pada kondisi penyimpanan terbaik. Benih kelapa sawit tergolong sebagai benih intermediat yang hanya dapat disimpan pada periode sekitar satu tahun. Penelitian ditujukan untuk melihat pengaruh matriconditioning terhadap viabilitas dan vigor benih kelapa sawit, khususnya yang telah disimpan lebih dari 1 tahun. Percobaan dilaksanakan dengan menggunakan rancangan acak lengkap faktorial. Faktor pertama adalah lot benih yaitu benih yang telah disimpan pada penyimpanan terkendali kurang dari 12 bulan (tiga ulangan, masing-masing telah tersimpan pada penyimpanan terkendali selama 3, 4, dan 9 bulan) dan benih yang telah disimpan pada penyimpanan terkendali lebih dari 12 bulan (tiga ulangan, masing-masing telah tersimpan pada penyimpanan terkendali selama 13, 14, dan 41 bulan). Faktor kedua adalah matriconditioning yang terdiri atas dua belas taraf yang merupakan kombinasi antara tiga media (zeolit, vermikulit, dan arang sekam) dengan empat larutan matriconditioning (emulsi Trichoderma sp., 2% KNO3, 2% KH2PO4, dan air). Perlakuan matriconditioning meningkatkan kelembapan udara (relative humidity, RH) secara nyata (98,3-99,9%) dibanding RH pada kontrol (75,33%), dan meningkatkan kadar air benih dari 15,7% (kontrol) menjadi 16,13-16,48% yang sesuai untuk tahap pematahan dormansi. Tidak terjadi peningkatan daya berkecambah (DB) yang signifikan pada perlakuan matriconditioning dibanding kontrol, namun peningkatan DB yang terjadi (4,3-12,6%) pada perlakuan matriconditioning menunjukkan aplikasi ini dapat diterapkan pada pengecambahan benih kelapa sawit yang telah disimpan lebih dari satu tahun. Penelitian ini juga menunjukkan bahwa penggunaan air dinilai cukup untuk aplikasi matriconditioning.

Abstract

The Community Engagement Program (PPM) organized by the Seed Industry Technology Study Program, Vocational School of IPB University, aims to address the challenges faced by the Women Farmers Group (Kelompok Wanita Tani, KWT) Ciharashas in Mulyaharja Village through training on vertical hydroponic techniques. This program encompasses problem identification, training, and optimizing greenhouse facilities. Problem identification revealed key issues such as greenhouse facility damage and the limited knowledge of KWT members regarding modern cultivation techniques. The training focused on vertical hydroponic system installation, nutrient management, and plant maintenance, emphasizing the efficient use of limited land. The greenhouse was repaired to support sustainable production and serve as a training hub. The training outcomes showed significant improvements in the understanding and skills of KWT members, as evidenced by pre-test and post-test results. Members are now capable of optimizing their yards, producing high-quality harvests, and increasing income through better marketing strategies. Post-training monitoring indicated the sustainability of the vertical hydroponic activities, with KWT members actively continuing the project independently. This program successfully created long-term positive impacts, including community empowerment, increased productivity, and sustainable agricultural solutions relevant to urban communities.

Abstract

Seed quality testing involves the evaluation of germination capacity under a standardized moisture content. However, limited reports have been found for seed testing methodology, especially for Amorphophallus muelleri. Standardizing the seed testing method for A. muelleri is essential to ensure repeatability, reproducibility, and reliable seed germination results. This study aimed to develop procedures for assessing seed moisture content and germination tests. Three seed lots were used for seed moisture content determination. The necessity for seed cutting and efficacy of high-temperature oven methods (133°C for 4, 5, and 6 h) were compared to low-temperature oven methods (103°C for 17 h). Five lots of seeds of different ages were used for the seed germination test using the between-paper method in a constant temperature germinator of 25 and 30 °C. There was no significant difference in the moisture content between the uncut/whole and the seeds cut. The high temperature of 133°C for four hours is an alternative to the low temperature. Germination rates at 25 and 30°C had no significant difference, i.e., 84 to 97% and 83 to 99%, respectively. However, at 30°C, it was shorter to 50% germination (T50) and germination period. Preheating the seeds for four weeks using the dry heat method shortened the seed germination time from 57 to 37 days. Seed lot exposed to dry heat had half the time required to reach T50, or 16.4 to 31.9 days after treatment, with a germination period of 37 to 52 days. The first count of germination at 25°C without preheating was 47 days after planting, and the final count was 73 days after planting, whereas at 30OC, it was 37 and 57 days after planting. The first and final count for germination with preheating treatment at both temperatures was 20 DAP and 37 DAP.

Abstract

The availability of seeds with known sex types is one of the obstacles in nutmeg cultivation. Epicotyl grafting using rootstocks aged 20–30 days is one of the solutions to overcome this issue. The objective of this study is to determine the optimal stage/age of rootstocks and the number of leaves of the scion to improve the success rate of nutmeg through epicotyl grafting. The experimental design used is a Randomized Block Design (RBD) with factorial pattern, repeated three times. The first factor is the stage of rootstock age, categorized as: 1 month (without leaves), 2 months (2 leaves), 3 months (3 leaves), and 4 months (4 leaves). The second factor is the number of leaves on the scion : 2 leaves cut in half, 2 leaves, and 3 leaves. Variables observation i.e. : a) C/N ratio in the rootstock and scion before grafting, b) plant morphology (Number of leaves, shoot length, shoot diameter, number of branches, and plant height.), and c) plant physiology (grafting success rate, graft union length, photosynthesis rate, and leaf chlorophyll content). The results showed that all rootstock stages and scion leaf number could be used for nutmeg grafting, with a 67-100% success rate. The best recommendation treatments are rootstocks with two leaves grafted to scions with two leaves, and rootstocks with four leaves grafted to scions with three leaves.

Abstract

​​Physical fitness is an essential factor in maintaining health and enhancing students' productivity. Nutritional status and physical activity play a significant role in determining an individual's level of physical fitness. This study aims to analyze the relationship between nutritional status and physical activity with physical fitness among students at Universitas Awal Bros. This research employs a cross-sectional design with a quantitative approach. The sample consists of students from Universitas Awal Bros selected using the purposive sampling method. Nutritional status was measured using the Body Mass Index (BMI), physical activity was assessed through a physical activity questionnaire, and physical fitness was evaluated using the Indonesian Physical Fitness Test (TKJI). Data analysis was conducted using statistical correlation tests to determine the relationships between the study variables.mThe results showed a significant relationship between nutritional status and physical activity with students' physical fitness levels (p < 0.05). Students with normal nutritional status and higher physical activity levels exhibited better physical fitness compared to those who were less active or had non-ideal nutritional status. Therefore, maintaining a balanced diet and engaging in regular physical activity is crucial for improving students' physical fitness.

Abstract

Soybean seeds deteriorate rapidly, especially under humid tropics. An effective method for boosting seed germination is invigoration, which is applied as a pre-planting seed treatment to stimulate the metabolic activity in the seed. The research aimed to compare the effectiveness of vermicompost priming with other invigoration methods in improving the physiological quality of soybean seeds. The experiment was arranged in a split-plot, randomized design. The main plots were seed lots based on low, medium, and high germination of three soybean varieties (“Argomulyo”, “Detap 1”, and “Devon 1”). Subplot, invigoration method: control, matriconditioning with rice husk charcoal, a ratio of seed (g): rice husk charcoal (g): water (mL) 9:6:7 for 12 hours; osmoconditioning with 15% PEG 6000 solution, a ratio of seed (g): solution (mL) was 1:2 for 12 hours, and vermicompost priming with a ratio of seed (g): vermicompost (g): water (mL) 12:14:12 for 18 hours. Each experimental unit used 120 g of seeds. The invigoration treatment was conducted in a room with a temperature of 25 ± 2°C and a relative humidity (RH) of 65-70%. The results showed that invigoration treatment can be used on soybean seeds with moderate viability (germination rate of 70-79%). In “Argomulyo” and “Detap 1”, the seed physiological quality increased with vermicompost priming, and in “Devon 1”, it increased with matriconditioning. The enhanced physiological quality of soybean seeds may be attributed to the complete nutrient and phytohormone content in vermicompost.
