Pink bollworm, P. gossypiella, is a main pest of cotton that causes boll damage up to 70%. Recommended IPM has not effectively control this pest. The use of parasitoids of this pest is one of strategy to manage this pest population as using chemical control is expensive and caused secondary pest. This research objective is to study some biological aspects of pink bollworm parasitoids by doing exploration of the parasitoids in cotton growing areas and testing the potential candidates as biocontrol agents. The activity was conducted from April - December 2001. The research was conducted in two steps: survey and laboratory tests. The survey was conducted in East Java (Asembagus and Lamongan), Central Java (Brebes) and South Sulawesi (Bone) by collecting pink bollworm eggs and identifying the emerged parasitoids. Laboratory tests were done in Biological Control Laboratory of ITFCRI, Malang, consists of reproductive performance aspects. We found two and five species of egg and larval parasitoids, respectively. Parasitism level of egg was 81% by Tichogrammatoidea spp. and that of larva was 24% by Apanteles sp. These two parasitoids are predominant and found in all cotton growing areas. Tichogrammatoidea spp. have opportunity to be used as biocontrol agent in release program, while Apanteles sp. would have valuable role in conservation approach.

Ikan pari merupakan salah satu jenis ikan yang banyak didaratkan berasal dari Selatan Jawa. Salah satu jenis ikanpari yang belum banyak dilakukan penelitian adalah ikan pari lampengan (Mobula japanica). Tujuan penelitian ini adalah untuk mengetahui tentang perikanan dan aspek biologi jenis ikan tersebut di perairan Selatan Jawa sebagai informasi dasar bagi penentuan kebijakan pengelolaan perikanan Elasmobranchii. Penelitian menggunakan metode survei yang berlangsung dari Januari hingga Desember 2010 di Pelabuhan Perikanan Samudera Cilacap-Jawa Tengah. Sejumlah 165 ikan pari yang tertangkap oleh jaring insang diamati tingkat kematangan seksual, tingkat kematangan gonad, jenis kelamin dan ukuran lebar cawannya.Wawancara dilakukan terhadap para nelayan dan nahkoda kapal yang menangkap ikan pari lampengen tersebut secara langsung dan atau oleh enumerator. Hasil penelitian menunjukkan bahwa tangkapan per satuan usaha (CPUE) ikan pari lampengan bervariasi, yakni tertinggi pada bulan Juli (22,6 kg/ hari) dan terendah pada bulan Oktober (6,6 kg/hari). Frekuensi lebar tubuh ikan pari lempengen terendah terdapat pada ukuran antara 100-140 cmdenganmodus 120 cmyang termasuk kelompokmuda, sedangkan ukuran antara 150- 200 cm dengan modus 170 cm, termasuk kelompok dewasa. Frekuensi lebar tubuh tertinggi terdapat pada ukuran antara 200-260 cmdenganmodus 230 cm. Ikan pari lempengen sedikitnya terdiri atas 3 kelompok umur dengan modus sebaran lebar tubuh masing-masing 120, 170, dan 230 cm. Hubungan lebar tubuh (y) dan panjang klasper (x)mengikuti persamaan y=0,3784e0,0131x (r2=0,85), semakin bertambah lebar tubuh semakin bertambah panjang klaspernya.Perbandingan kelamin jantan dan betina adalah tidak seimbang (1,5:1). Sebagian besar kelompok umur ikan pari lampengan yang tertangkap tergolong usia muda, yang belummencapai pertumbuhan optimum(growth over fishing). Stingray is one of the species of fish that many landed came from the South of Java. One of the species that have not many research is JapaneseDevilray (Mobula japanica). The purpose of this study was to determine fisheries and biological aspects of Japanese Devilray, Mobula japanica in Indian Ocean as basic information for managing the elasmobranches fisheries. This study was conducted from January to December 2010 in the Ocean Fishing Port of Cilacap, Central Java. A total number of 165 individu of M. japanica caught by seine net and tuna longline were observed during the sampling periods. Body wide, sex, and gonadmaturation of those fishes were analyzed. Interviewswere also done to the fisherman and fishing master. The results showed that the body width of stingrays, M. japanica had the lowest frequency between 100-140 cm with mode of 120 cm,and grouped as young fish.Other groups has body width between 150-200 cm with mode 170 cm, and grouped as adult fishes. While the frequency of the highest body width was between 200-260 cm and 230 cmmode. At least, there were 3 cohorts ofM. japanica found in this study with the body width mode of 120, 170 and 230 cm. Exponential relationship between body width (y) and claspers’ length (x) was observed forM. japanica, that expressed by equation: y=0.3784e 0.0131x (r2=0.85), that mean the more width fish body, the more increase claspers’ length. Unbalance sex ratio of 1.5:1 was observed for this fish. CPUE for M. japanica were varied between 6,6 kg/day during October and 22,6 kg/day 0n July. Most of fish caught were young fishes under their maturity stages that indicated a tendency of growth over fishing.

Abstract The provision of agricultural machinery in the Modern Agriculture Program is to overcome labor shortages. However, the utilization of agricultural machinery aid is underutilized. This study aims to analyze the optimization of the use of agricultural machinery in enhancing the implementation of modern agricultural programs. West Sumatera, Central Java, Banten, Bali, and South Sulawesi were purposively chosen as the study areas. The study was conducted in 2017. Respondents of this research were policymakers from central to local institutions, key informants, extension agents, agricultural machinery service providers (UPJA), and farmers. The method used was descriptive explanatory and financial analysis. The results showed that the utilization of agricultural machinery in the Modern Agricultural Program was still not optimal. It was still underutilized. There were several obstacles, both from economic and social aspects. The utilization of 4-wheel tractors and rice transplanters has not been economically managed. As a result, they cannot generate funds for equipment maintenance and the development and UPJA’s sustainability. Not all types of agricultural machinery are socially suitable for farmers’ needs. There is a competition between agricultural machinery uses and workers. Moreover, not all local governments fully supports agricultural machinery uses. To optimize and succeed on the modern agriculture program implementation, agricultural extension workers with certification as UPJA Facilitators are required.

Oktaviani D, Faizah R, Nugroho D. 2018. Biological aspects of Longfin Mojarra (Pentaprion longimanus, Cantor 1849) in north coast of Central Java, Indonesia. Biodiversitas 19: 683-689. Longfin Mojarra (Pentaprion longimanus) locally named as rengganis, is a demersal fish species that is commonly caught in Scottish seine fisheries off the north coast of Java. The fisheries are in heavily harvest level since decades. The aim of this study was to observe the biological aspects of this species. Observations were made between August 2014-July 2015 from Tegal fishing port, western part of north coast central Java. General life-history parameters were measured, i.e., monthly length frequency for 1876 fishes, among them 573 specimens were observed for length-weight relationship, including 541 specimens for sex ratio and maturity stages. Fulton index, Gonadosomatic index, sex ratio and estimated length at first mature were analyzed. The result showed fish size ranged between 7.4 to 15.3 cmFL with the average length of 11.2+1.75 cmFL. We found that length-weight relationship tends to be isometric which statistically the body growth coefficient (b) is equal to 3 (tc = 0.53 < tab; p<0.05) . Monthly Fulton indexes ranged between 1.05-2.87 with an average of 1.90 + 0.17. Sex ratio during observation was not significantly different (p<0.05) from the expected ratio of 1: 1. Mature females occurred year-round with the highest percentage observed from January to April 2015. The estimated length at first maturity was 13.04 cm FL. These biological parameters will be used to support the population study of the future demersal fish species to improve conservation and management measures.
